Building glass on how to avoid the tempered glass blew?
1, the choice of ultra-white original film;
2, hot dip treatment;
3, the appropriate control of single-chip glass weight, to avoid monolithic glass too heavy too heavy.
What is the rate of blasting?
Due to the existence of polished glass this objective phenomenon. According to statistics at home and abroad, the general situation every 4 tons of glass there is an example of "blew", into a conventional glass specific number, is the industry's 3 ‰ -5 ‰. From the engineering practice, the quality of the original film, the size of the glass layout, the control of the deep processing technology has a greater impact on the probability of blew.
The influence of the quality of the original film on the probability of blew is decisive. (1) The nickel-iron alloy linings used in the production of sand, furnish, fuel, and even crusher together determine the material base of nickel sulfide; (2) raw material management, melting and molding in the process of float production Process management, erosion of refractories, etc., determines the original glass of stones, bubbles and other impurities in the number. ③ Float production process in the cold end of the detection of impurities and treatment methods also determine the flow of deep processing plant to the original film quality.
The factors that affect the probability of blemish during deep processing are as follows: (1) the quality of the edge treatment; the microcracks at the edge of the glass directly affect the bleaching of the steel during the process. While the edge of the rough processing of the glass, there are also installed in the installation of the edge of the crack propagation and glass blew the situation. ② the higher the steel stress, the higher the probability of tempered glass blew.
How does the tempered glass blew?
The difference between the steel blew and the tempered glass external force crushing is mainly due to the difference of "starting point". Tempered glass blews generally in the center of the glass. Initiation point of the center there are obvious fragments were butterfly-like, commonly known as: "Butterfly spot."
Tempered glass external impact crushing generally visible in the crushing point traces, no butterfly spot. The glass is broken from the impact point of the radioactive distribution.
Tempered glass blew small knowledge, you get it?
Tempered glass blew is the automatic cracking of tempered glass in the absence of direct mechanical external force. There are many reasons to produce blew, simply sum up the following: ①, glass stones, impurities, bubbles: glass impurities are tempered glass is weak, but also stress concentration. In particular, if the stone in the tempered glass tensile area is an important factor leading to burst. ②, glass containing nickel sulfide crystals, nickel sulfide crystal phase change caused by changes in the tempered glass blew. ③, the glass surface due to processing or improper operation caused by scratches, fried mouth, deep burst edge and other defects, easy to cause stress concentration or lead to tempered glass blew. ④, the uneven distribution of stress in the tempered glass, offset or stress caused by high.
In general, the glass of the steel processing process occurs from the cause of blew to the situation ③, ④ mostly; glass factory blew after the situation ①, ② mostly; glass installation is often completed after the case is the most typical.

High-iron glass: four secrets you do not know
Secret one: why do not look out the window does not stare the scene is not deformed?
Glass refractive index of the same train damping performance is good
High-iron car front window glass is a hyperboloid structure, the glass itself has a lot of layers, between layers and layers to maintain a high degree of consistency, this will not affect the optical effect of glass to see things not deformed. High-caliber side window glass visual effect is excellent, improve the glass in the thickness, flatness on the error, and do the glass material composition of the full homogenization, to ensure that the same refractive index, see the scene will not be deformed, and no glass Visual effects, looks comfortable, not dazzling.
The ordinary glass due to the existence of a certain optical distortion, through the glass to see the scene will produce deformation, at the same time, for high-speed movement of the scene will produce the speed of superposition, resulting in dazzling, bring a sense of dizzy. High-speed EMU train shock absorption performance is good, irregular bumps reduced, the scene shaking smaller, running very smooth, quiet, to the passengers with a slow feeling, the passengers sit there will not have a sense of dizzy.
Secret II: high-speed rail operation in the process of encounter small stones will be broken it?
The window can not be urged to withstand the speed of 355 km of aluminum bomb impact!
The current high-speed rail train running speed of 380 km / h, high speed also means that high-risk, high-speed train will be around the air compression, air resistance greatly improved, which makes the train in the process of moving through a road Brick wall, the resistance can be imagined. Therefore, in order to ensure the safety of the train, the most vulnerable windshield in the train must be hard to remind.
High - iron glass impact test
The above video is the impact test of high-iron glass, 1kg heavy aluminum bombs at a speed of 355 km per hour to the high-speed rail train on the glass, although the floor is broken glass, the window was aluminum bombs hit a pit, but the glass And was not penetrated and off the box, the window and no glass slag splash, hand hit the impact area is still very strong.
High-speed rail special attention to high-speed impact of glass material performance, which is the glass processing enterprises in the production of a threshold. Take the CRH380A EMU as an example, which requires the front windshield to withstand 1kg of aluminum bombs at a speed of 540km / h and can not be penetrated. Side window glass requires good visual performance, safety performance, energy saving performance and environmental performance.
Your windshield is not clean? A solution to solve
Glass rust
Mentioned glass rust some people think that glass is not how the metal may rust, but many people will appear on the glass glass rust. This is really difficult to clean, I believe many people used toothpaste, washing spirit, washing powder, etc., these are useless. In fact, there are ways, as long as the first wipe with a damp cloth, and then use a dry cloth stained with alcohol to wipe the windshield, will soon be able to see the effect.
Oil film
Many people say that their own windshield appeared on a layer of something similar to oil, how to wash are not clean.
1, with the kitchen clean the oil stains on the glass, and then wipe back and forth with a wiper to clean the water.
2, with toothpaste and sponge, the toothpaste applied to the windshield in the car, try to smear evenly.
3, a professional oil film cleaning agent, preferably with flooding agent better Oh!
4, the use of ammonia to wipe, only need to add a small amount of water in the water on the line, so you can make the owner of the car glass becomes very bright.
Spots
The spot can be directly washed with glass of water, if not can also use toothpaste, these spots are generally rain stains, clean up or very simple.
Floating dust
Dust is easy to deal with, the windshield of the windshield of the wind when the first time you gently rub with a cloth, and then use glass water can be cleaned. If the wiper is not clean, the wiper is aging or the wiper has an angle. If it is a wiper angle problems can adjust their own, you can also adjust the distance of the spring.
The front of the windshield clean or not in addition to affecting the aesthetic will affect the safety of driving, after all, when the rain is not high visibility, coupled with their own front windshield is not clear even more dangerous. So be sure to pay attention to the above aspects, in the rainy season before the arrival of the wiper to check Oh!

How to maintain glass What glass can be maintained
Glass is like a person's eyes, which determines the safety of people looking at things. Glass can not get immediate conservation will bring people all kinds of trouble, some people in the maintenance of glass, only to some of the big trouble for maintenance, in fact, there are many small details have not been dealt with, it is easy to ignore the glass , If those who will be careful to clean the glass clean, but also bring their own look very clean, the mood will be better.
1, usually do not force the collision glass surface, for the anti-glass surface scratches, the best shop on the tablecloth. When you put things on the glass furniture, to gently, avoid collision.
2, daily cleaning, wipe with a wet towel or newspaper can be, in case of stains can be towel dipped in beer or warm vinegar to erase, you can also use the market to sell glass cleaning agent, avoid acidity Strong solution is clean. Winter glass surface easy to frost, can be dipped in salt water or white wine to wipe, the effect is very good.
3, a pattern of wool glass once dirty, can be dipped in a toothbrush with detergent, along the pattern can be removed to remove the circular wipe. In addition, you can also drop the kerosene on the glass or with chalk ash and gypsum powder dipped in water on the glass to dry, and then wipe with a clean cloth or cotton, so that the glass is clean and bright.
4, the best glass furniture placed in a more fixed place, do not arbitrarily move back and forth; to place objects smoothly, heavy objects should be placed at the bottom of glass furniture to prevent the furniture center of gravity caused by instability. In addition, to avoid moisture, away from the stove, with acid, alkali and other chemical reagents isolated to prevent corrosion deterioration.
5, the use of plastic wrap and sprayed with a wet cloth can also be so often stained with oil glass "regain new life." First of all, the glass was completely sprayed with detergent, and then paste the plastic wrap, so that the solidification of the oil softening, after ten minutes, tear off the plastic wrap, and then wipe with a damp cloth. In order to keep the glass bright and clean, you must always hands clean, glass if there is a handwriting, can be used rubber water immersion friction, and then wipe with a damp cloth; glass if the paint, cotton can be dipped in vinegar scrub; clean with a dry cloth dipped in alcohol glass , Can make it bright as crystal.
There are five precautions:
1, in the transport process in order to avoid unnecessary losses, we must pay attention to fixed and soft pad. It is generally recommended to use an upright method of transport. Vehicles should also be kept steady and slow.
2, the other side of the glass installation is closed, pay attention to clean the surface before installation. It is best to use a dedicated glass cleaner, and to be dry after confirming that there is no stains before installation, the installation of the best use of clean building gloves.
3, the installation of glass, to use silicone sealant for fixed, in the windows and other installation, but also with the rubber seal with the use.
4, after the completion of construction, we should pay attention to stickers anti-collision warning signs, generally can not use stickers, color electrical tape, etc. to be prompted.
5, do not use sharp objects collision.
Wipe the glass
1, wipe the glass: first with a towel to wipe the glass frame, and then stained with glass after the dilution of the glass aqueous solution, even from top to bottom smear the glass, and then repeat the above process, with a glass scraping from scratch to clean, Dry towel to clean the water marks left on the box, the water marks on the glass must be wiped clean with glass, otherwise it will leave a trail on the glass.
2, the vinegar and water by 1: 2 ratio of harmony, into the spray, spray on the glass and then wipe, you can polish very clean.
3, in the basin by adding 5% of the Ammonia solution or gasoline, with its cleaning glass, until the glass is dry and then wipe clean with a dry cloth, the glass can be spotless, bright and transparent. In the wipe of the glass, you can use the different models with a different window to see whether it is double glass or double glass. Use the wiping window to facilitate, effort and safety.
4, such as glass surface moldy phenomenon, can be hydrofluoric acid (HF) and water 1: 8 ratio of reconciliation (Note: more than 1: 8, will cause damage to the hand), wipe the glass. Note: must do a good job of corrosion protection work, the skin can not contact HF, otherwise it will be serious corrosion! Wipe the glass, wipe with water again, and finally the glass dry.
