The difference between hot-dip galvanized steel pipe and cold-galvanized steel pipe

The difference between hot-dip galvanized steel pipe and cold-galvanized steel pipe, hot-dip galvanized steel pipe and cold-galvanized steel pipe are called galvanized steel pipe, galvanized steel pipe is divided into two kinds, one is hot-dip galvanized steel pipe, one is Cold-galvanized steel pipe, cold-galvanized steel pipe is electro-galvanized steel pipe, the content of galvanizing is very small, only about 10 grams to 20 grams per square meter, its corrosion resistance is very poor compared with hot-dip galvanized steel pipe, hot-dip galvanized 4×4 square steel tubing The corrosion resistance is dozens of times that of cold-galvanized steel pipes. Let’s take a look at the differences between hot-dip galvanized steel pipes and cold-galvanized steel pipes.

Hot-dip galvanized pipes are galvanized for general steel pipes in order to improve the corrosion resistance of steel pipes. The galvanized steel pipe is divided into two types: hot-dip galvanizing and electro-galvanizing. The hot-dip galvanizing layer is thick, the cost of electro-galvanizing is low, and the surface smoothness is reduced.

The difference between hot-dip galvanized steel pipe and cold-galvanized steel pipe

The first type: cold-galvanized pipe and hot-dip galvanized pipe have a big difference in the way of operation. Zinc in hot-dip galvanizing is zinc obtained at 450 degrees Celsius to 480 degrees Celsius, and zinc in cold-galvanized steel pipes is zinc obtained by electroplating at normal temperature.

The second type: cold galvanized pipe and hot-dip galvanized pipe have a great difference in the thickness of the galvanized layer. The thickness of zinc in the hot-dip galvanized steel pipe is much thicker than the thickness of the zinc in the cold-galvanized steel pipe.

The third type: cold-galvanized pipe and hot-dip galvanized pipe have great difference in surface smoothness. The surface of cold-galvanized steel pipe is much rougher than that of hot-dip galvanized steel pipe.

The fourth type: cold-galvanized pipe and hot-dip galvanized pipe also have great differences in price. Hot-dip galvanized steel pipes are produced by regular galvanized pipe manufacturers. In order to ensure the quality of galvanized pipes, they generally In the case of galvanizing, the galvanizing method is not used, and those with relatively old equipment and small scales mostly adopt the mode of electro-galvanizing seamless steel line pipe. Naturally, cold-galvanized steel pipes are much cheaper than hot-dip galvanized steel pipes.

The fifth type: the cold-galvanized steel pipe is only one side of the galvanized steel pipe, and the hot-dip galvanized steel pipe is to be fully galvanized.

Sixth: Cold-galvanized pipe and hot-dip galvanized pipe also have great differences in adhesion. The adhesion of cold-galvanized steel pipe is much worse than that of hot-dip galvanized steel pipe because of the cold-galvanized steel pipe. The matrix and the zinc layer are independent, the zinc layer is very thin, and it is simply attached to the steel pipe base, so the cold-galvanized steel pipe is easy to fall off.

The cold-galvanized steel pipe adopts an electroplating process and is only galvanized on the outer wall of the steel pipe, and the inner wall of the steel pipe is not galvanized; the hot-dip galvanized steel pipe adopts a hot dip galvanizing process, and the inner and outer walls of the steel pipe have a zinc layer.

The difference between the hot-dip galvanized steel pipe and the cold-galvanized steel pipe shared today is here. The difference between the two is in addition to the above, the biggest difference is the corrosion resistance. The cold-galvanized steel pipe has very little galvanizing. 10-50g/m2, hot-dip galvanizing is several times higher, obviously safer.

The intensity of PV module

The intensity of each PV module is unique, contingent upon the procedure and quality control, obviously, the higher procedure and quality control items Steel Omega profiles, the cost is normally higher. On account of fixed item decisions, it is important to consider the accompanying angles to expand control age:

1.dust evacuation framework, this ought to be a minimal effort, great impact framework, after the parts are tidied, the characteristic power age is diminished, straightforward residue expulsion can be washed with water, this should be possible physically.

The most effective method to build the measure of power created by photovoltaic frameworks

2.concentrating framework, practice has demonstrated that including concentrating framework the part can build the power age by in excess of multiple times. This innovation isn’t prevalent in local application. It exists in the concentrating and won’t overheat because of parts. What’s more, diminish the life, excessively exact, staggering expense and other details.Steel Profile providers

3.Chasing the Japanese framework, the establishment of shabby segments, the segments are fixed, which normally can’t boost the light fascination. Practice has demonstrated that a decent pursuing framework can significantly build the unit control age. Normally, the framework increments. It is likewise an expansion in establishment cost.

A few kinds of transformer determination procedures usually utilized in photovoltaic frameworks in medium and huge scale ventures?

1.Electrical separation: The essential and optional of the segregation transformer are fueled by attractive circuit. The segments are electrically secluded from the framework, which can counteract the DC segment and spillage flow from entering the lattice. It is appropriate for the part negative establishing framework.

2.matching voltage: Some nations’ framework voltage is unique in relation to that in China. For instance, the US is single-stage 110V, three-stage 220V, and a transformer can be added behind the inverter to coordinate the voltage of the entrance nation.

3.In the concealment segment PID arrangement, the detachment transformer is associated behind the inverter, and after that the capability of the N-post of the photovoltaic framework is raised, and the capability of the negative shaft of the part is in a roundabout way raised to accomplish the reason for stifling the segment PID.

Disney’s resistance rises

Although the media guests did not complete the process, the drills provided were surprising. When the group left the ship after being captured by the first command, an audible gasp sounded. Waiting for more than 30 stormtroopers in huge hangers, all attracted attention.

Even without electronic animation or expansive music, this scene is awesome. Photography in this space is prohibited, and the media requires that their mobile phones and video equipment be packed before entering the space. Disney is keen to keep most of the surprises and secrets of this ride until fans can experience it themselves.

Disney's resistance rises

However, Chapek and Trowbridge did provide some insights into the journey of innovation. In the pre-show preview video, Vi Moradi is a new character created for the park and appeared in a newly released novel called “The Milky Way: Black Spire”. The heroes are welcome to resist but warn them of the danger ahead.

The large AT-AT vessel was fired on an eight-passenger vehicle driven by an R5 robot. The stormtroopers stared at the newly captured prisoner and a red light sword knife attempted to tear the ceiling of the transport ship.

Trowbridge said that the last moment of “kicking” appeared at the last moment. Once the capture of the resistance member and the cat-and-mouse game between the first sequence ends, the trackless vehicle enters the escape capsule and enters space.

“Rise of Resistance” has more than one riding system, and both Chapek and Trowbridge are joking on Tuesday. Parked vehicles parked throughout the journey actually travel to many other vehicles to achieve different types of motion.

“This will hit people’s minds,” said the visionary Chris Beatty. “This is unique and completely different, unlike anything we have developed so far.”

Beatty said that no matter how immersed in the legend of Star Wars, and it is both exciting and family-friendly, park visitors will be able to enjoy cycling.

“People will leave and go, ‘How did they do it?’” he said.

Although the Orlando version is expected to be operational on December 5th, its California model will open on January 17. Disney initially expected two parking spaces to be open by the end of 2019.

Although some speculate that the ride will be open later, because it includes the spoiler of “Star Wars: The Rise of the Skywalker”, released in Orlando in early December – a few weeks before the film’s December 20 release date – seems to refute That statement.

Other rumors focus on driving that may have technical difficulties. When asked about the opportunity, Chapek said that Disney wants to ensure the reliability of the ride and prepare for the guests.

“The secret is that we don’t plan to line up,” he said. “The focus is on building capacity. The ten-hour route is not successful… we are trying to avoid this.”

What kind of exercise is good for our body

When it comes to sports, for some people, it is not too tired, and for others, it is prohibitive. In fact, exercise is not so difficult. Exercise requires a spirit of perseverance, and continuous efforts can ensure the health of our body. The benefits of sports are numerous, let us take action and actively participate in the sport! But what kind of exercise is good for our body?

Swim.

Swimming is a good way to exercise and loved by many friends. It not only avoids the fatigue consumption of sweating, but also can effectively play the role of fitness shaping. If you are afraid of the sweaty exercise, then choose to swim to exercise! It’s easy to swim in the water like a fish, and it’s easy to say.

What kind of exercise is good for our body

Yoga.

Yoga is a relatively soothing exercise. Yoga has no age and gender requirements, so you can participate as long as you are passionate about yoga. Seemingly simple yoga movements, if you really want to do the action in place, it is not a day’s work. In addition, yoga can very well hone people’s temperament and train the body’s flexibility. It is also a good way to exercise.

Tai Ji.

Tai Chi, soft and soft, just as soft and gentle, has been loved by many elderly friends. The movement of Tai Chi is also relatively soothing, especially suitable for old friends to practice. Taijiquan has a long history and can be passed down from ancient times to the present. It must have its advantages. Interested elderly friends can try to insist on playing Tai Chi is very beneficial to the body.

jogging.

Jogging is also a good sport. Jogging is the training of endurance. Only by breaking through the limit can you stick to it better. Although jogging can be a bit boring, but to know any kind of exercise, for a long time, there will be a sense of boring, relying on confidence and perseverance to last forever, if you like to jog this way of movement, whether it is The gym is still in the big playground of the school. You can wear headphones and listen to music while jogging. You won’t feel bored.

Sit-ups.

Sit-ups can work well on the abdominal muscles without any limitation, and can be done in the bed. However, it should be noted that the bed should not be too soft, and the soft bed can not achieve the effect of exercise. If you want to have a flat stomach, you can’t do it overnight, so sit-ups are also expensive.

Is it hard to find a good movie

It’s hard to find a movie to watch. A recent Netflix study showed that we spent 18 minutes a day looking for a movie – which may not include Catholics, who also have a potentially harmful content behind their thoughts. It is worth seeing.

Most of the movies that appear every year are not worth seeing because they are of poor quality and there are still a lot of bad things: nudity, language, violence, and so on.

So what is a Catholic? Do we want to avoid any movies with offensive content? This didn’t leave us too much – in fact it is harmful to most of the high quality movies that appear every year.

Is it hard to find a good movie

It turns out that São Paulo did give us some thoughts when we were spending.

In Philippians 4:8, he said: “The last brother, whatever is true, what is glorious, what is right, what is pure, what is lovely, what is a good reputation, if Have any excellence and anything worthy of praise, talk about these things.”

If there is anything good, beautiful or true – those are worth something. If a film has these qualities, it is worth seeing because it involves God in a very small way.

But this does not mean that it must explicitly involve God.

Don Woznicki, director of New Ethos, is an advocate for collecting films that reflect truth, beauty and kindness. He told the Catholic News Agency that films of these qualities are about transformation and transformation.

“The new spirit is not just to support the film and entertainment media, because Catholics created it,” Father Woznicki told CNA. “Would you fly in the air because of the Catholic voice? Quality is the rule. Christ constantly calls us to change, hope and transform into his image.

“The new national spirit film is not to promote the disinfection of Christianity, but to transform, hope and change.”

So how can you see which movies or shows are worth seeing? First, I always look at the IMDB’s Parent Guide section, which describes any sexual content, embarrassment or violence, so I have a better understanding of what I am entering.

Two basic types of sleep

Sleep is an important part of your daily life – you spend about a third of your time doing it. Good sleep – get enough sleep at the right time – essential for food and water survival. Without sleep, you can’t form or maintain pathways in your brain, let you learn and create new memories, and it’s harder to focus and react quickly.

Sleep is important for many brain functions, including how nerve cells (neurons) communicate with each other. In fact, your brain and body stay very active while you sleep. Recent research has shown that sleep acts as a housekeeper and removes toxins from the brain that accumulate when you are awake.

Two basic types of sleep

Everyone needs to sleep, but its biological purpose is still a mystery. Sleep affects almost all types of tissues and systems in the body – from the brain, heart and lungs to metabolism, immune function, mood and disease resistance. Studies have shown that long-term lack of sleep or poor sleep quality increases the risk of high blood pressure, cardiovascular disease, diabetes, depression and obesity.

Sleep is a complex and dynamic process that affects how scientists now begin to understand. This booklet describes how your sleep needs are regulated and what happens in your brain during sleep.

There are two basic types of sleep: rapid eye movement (REM) sleep and non-rapid eye movement sleep (in three different stages). Each is associated with specific brain waves and neuronal activity. On a typical night, you can cycle several times in all phases of non-REM and REM sleep, and in the morning there is a longer, deeper REM cycle.

Stage 1 non-REM sleep is a shift from awakening to sleep. During this relatively light sleep (for a few minutes), your heartbeat, breathing and eye movements slow down and your muscles relax during occasional convulsions. Your brainwaves start to slow down from the awake mode during the day.

Stage 2 non-REM sleep is a mild sleep before entering deep sleep. Your heartbeat and breathing are slow and your muscles are further relaxed. Your body temperature drops and your eye movements stop. Brainwave activity slows but is characterized by transient electrical activity. In Stage 2 sleep, you spend more repetitive sleep cycles than other sleep stages.

Stage 3 non-REM sleep is a deep sleep period that you need to feel refreshed in the morning. It happened in the longer period of the last half of the night. Your heartbeat and breathing will be reduced to a minimum when you sleep. Your muscles are very relaxed and it may be difficult to wake you up. Brain waves become slower.

REM sleep first occurs about 90 minutes after sleep. Your eyes move quickly from one side to the other behind the closed eyelids. Mixed-frequency brainwave activity becomes closer to what is seen in waking. Your breathing becomes faster and more irregular, and your heart rate and blood pressure increase to near-awake levels. Most of your dreams occur during REM sleep, although some may occur in non-REM sleep. Your arm and leg muscles are temporarily paralyzed, which will prevent you from showing your dreams. As you get older, your sleep time in REM sleep will decrease. Memory integration is most likely to require non-REM and REM sleep.

Six steps to help you be stronger

You don’t need fancy fitness equipment to get a strong engraved back. All you need is a set of dumbbells, 15 minutes, and some motivation. To help you achieve your back build and posture goals, Celebrity Fitness Coach and “Revenge Body” star Lacestone provide you with the best dumbbell back movements.

Choose the following steps. For each move, perform 20 repetitions and proceed to the next step. The entire three times of moving circuits are repeated three times in total.

Six steps to help you be stronger

1.Underhand Bent-Over Row:
How to: Grab a pair of dumbbells, stand with your feet apart, and bend your knees slightly. Hinged forward from the hips, lowering the chest toward the floor, arms hanging directly on the shoulders, palms facing away from you. Support your core, then pull the weight toward the chest and squeeze the shoulder blades together. Pause, then lower the start. That is a representative. Do 20 times.One-arm bending line:
How to: Take a dumbbell with your left hand, stand with your feet apart, and bend your knees slightly. Hinged forward from the buttocks, lowering the chest to the floor, letting the left arm hang directly on the shoulder, and the right hand on the hip pocket, facing the midline of the body. Support your core, then pull the dumbbells into the chest and squeeze the shoulder blades together. Pause, then lower the start. That is a representative. Do 20 times on each side.

2.One-legged line:
How to: Hold the dumbbell in your left hand and palm toward the center line. Tilt forward, as you lower your torso and raise your left leg until your chest and legs are parallel to the floor, let the weight hang directly under the shoulder. This is your starting point. Pull the dumbbell to the chest; pause, then slowly lower it back to start. That is a representative. Do 20 times on each side.

3.One-arm rear lift:
How to: Grab the dumbbell with one hand, bend the hip forward, and place the other hand on a stable surface. Let the dumbbells straight down from the shoulders with the palms facing forward. With your torso moving, straighten your arms back until you are consistent with your body. Pause, then slowly return to the starting position. That is a representative. Do 20 times on each side.

4.Alternate reverse flight:
How to: Grab a pair of dumbbells, stand with your feet apart and bend your knees. Roll your hips forward, let your arms go straight down from your shoulders, and your palms face your body. When squeezing the shoulder blades together, lift one arm to the sides. Go back to the beginning. That is a representative. Do 20 times on each side.

5.Alternate reverse flight:
How to: Grab a pair of dumbbells, stand with your feet apart and bend your knees. Roll your hips forward, let your arms go straight down from your shoulders, and your palms face your body. When squeezing the shoulder blades together, lift one arm to the sides. Go back to the beginning. That is a representative. Do 20 times on each side.

6.Renegade Row:
How to: Assume that the hands are placed on the weights, the arms are stretched, the palms face each other, the wrists are not creased, and the feet are slightly wider than the hip width. Bend one arm and raise the dumbbell to the chest level, keeping the hips and shoulders level. Lower the weight of the floor and repeat the movement by swiping another dumbbell. That is a representative. Do 20 times.

You should keep relax

When you encounter something you fell very anxiety or pissed off,in this time,you should keep relax,because if you always keep anxiety or pissed off in your deep,it will serious damage to your health.Now,let’s learn some ways to relax together.

How to make yourself relax?If you always fell very anxiety or pissed off,you can try:

You should keep relax

1.Positive psychological suggestion.we should as much as possible forget all of negative thinking activity,think more positive and expected things,so that we can finally succeed.

2.Hear some music.we can choose a song with a strong sense of rhythm and a cheerful atmosphere,use those kind of music to help “waking up” our emotional state and energy levels.

3.Adequate preparation. The expressor can reinforce and reinforce the confidence and eliminate the inner tension. Global speech champion Craig said: When I was standing there facing thousands of eyes, I was already in my own home, in the mirror, and made more than a thousand times to my family and friends. So, when I really stood under the spotlight and started speaking, I felt very comfortable and relaxed, just like I was at home.

4.Take a deep breath. When you close your eyes and take a deep breath, because you concentrate all your attention, you can gradually eliminate all distractions and achieve the effect of eliminating tension and self-relaxation. Here we recommend the “Russian Breathing Method”: when you exhale, you don’t need a nose to call, but the teeth close together, and slowly exhale with your mouth. When the airflow passes through the teeth, it emits a “beep” like a rattlesnake. sound.

5.Having snack. The text only recommends that the speaker eat a small packet of almonds 10 to 15 minutes before the opening. Because when you are in a state of threat or tension, people will find that they are always dry, because in this state, our brain is running at a high speed, thinking about how to effectively deal with external threats. At this time, the mouth will stop secreting saliva.So, before you start speaking, eat a small packet of almonds, one for your own energy, and more importantly, let the mouth fully release saliva, which in turn will send a signal to your brain, I am now in a safe state.

6.Facing friendly. When you start, you should never look for those who have a cold face and a serious look. And go find those friendly, kind, smiling listeners. You can even find one or two”childcare” and let them actively cooperate. This can also help us overcome tensions.

The above is a brief introduction to the methods of relieving anxiety and anger. When you are in a bad mood, you may wish to try like those. You will find that nothing is worthy of excessive anxiety and anger, and you will feel very relaxed.Also because of this, there will be no physical discomfort caused by poor mood.
