development and the development of modern glass exterior of the car is closely related. As early as 40 years ago, car windshield has a single-piece curved windscreen, and gradually abandoned planar windshield. Today’s car windshields are generally made of a type of large overall surface type, up and down has a certain arc. Such curved glass, whether from the process or from a mating set into perspective, is a very high technical requirements of the product, as it relates to vehicles, strength, insulation and assembly problems.

1. The windshield classification
As early as 80 years ago, the glass has been widely installed in the T-car Ford plant produced, flat glass was installed in the cabin so that motorists exempt from the wind and rain of pain. From among the next few years, the glass industry gradually get involved in the automotive industry, to create a variety of safety glass: laminated glass, tempered glass and tempered glass and other regional varieties, which greatly improved the performance of automotive glass.
Laminated glass is used in a transparent plastic film may be attached to the adhesive between the two or three layers of glass, the strong plasticToughness and hardness of the glass together, increased resistance to crushing capacity glass. Tempered glass is ordinary glass quenching refers to the internal stress of a certain tissue, such that the enhanced strength of the glass, when broken by the impact, the glass will be split into small pieces with a blunt edge, and not harm the occupant. The glass area is a new breed of tempered glass, which is specially treated, can break upon impact, which can crack the glass still maintain a certain clarity to ensure that the driver’s field of vision area is not affected. Currently before the car windshield with laminated glass and laminated glass area-based, can withstand strong impact. .
2 Maintenance
the rational use of water glass
now glass of water the type sold in the domestic market a wide range, but mainly divided into three types: summer Glass water, winter frost glass of water and antifreeze glass of water effects. Wherein the water glass is mainly used to remove a summer flies residue on the mirror surface.
Among the usual glass maintenance process, to select a suitable glass of water depending on the circumstances of the weather and the season. When the windshield glass surface blur found when cleaning will be much brighter with a suitable water glass. And identify problems at night chaos reflective glass, a glass can be wiped with water. Also in the case of high-speed running or dusty, with a glass of water would be very fast, but also pay attention to immediate injection of new glass of water.
Some owners that only glass cleaning decontamination wash it, so instead of glass with a detergent or a detergent water; FIG some owners more expensive, instead of directly with water, the presence of theseRisks. Detergents and other chemical detergents has some precipitate a long time easily corroded rubber tube, and will plug the spout, severe cases can damage the motor. General corrosion detergent rubber tube will continue to accelerate the curing catalyst wiper strip. Hardening of the strip when scratched windshield, will accelerate the windshield surface being shaved scratches. If you replace the wiper, to pay the costs will be several times the price of a glass of water.
Although the ordinary water is very clean, but the chemical residue which is also very much over time can also lead to blockage of the spout spray impact. If long-term use will increase the friction mirror, easy to make minor scratches left wiper cleaning a mirror surface.
The use of water glass
The so-called water glass is commonly known in the automotive windshield washer fluid, are used in automotive consumables. In general, the glass of water on our goods retail market can be divided into three: one summer commonly used in the cleaning solution in addition to increasing the shellac component, you can quickly remove the residue on the insects hit the windshield; a designed as a kind of antifreeze glass cleaning liquid for winter use, to ensure that when the outside temperature is below minus 20 ℃, still will not freeze frozen car facilities; one is the effects of antifreeze to ensure that still does not freeze at minus 40 ℃, for the most northern part of our country’s cold regions.
When you feel the car’s front windshield poor transparency, and this time sprays glass of water, you will be able to give a “clear and bright” vision. Especially when driving at night, glass dust may scatter light, this time need sprays water glass, so that the transparent windshield in the best state. In addition, in dusty environments, and run in the rain when the highway, glass water consumption will be very fast.
Some owners believe that washing the front windshield glass of water, as long as it can stain removal cleaning, usually with water, detergent, detergent having this effect, so will detergent, washed agents, detergents and other against a little water to replace the special glass of water, I feel so cheap and peace of mind; and some owners to replace the direct use of water glass of water. In fact, this practice there are certain risks.
For example, the water against water detergent washing powder have some precipitate a long time, not only will corrode rubber tube, and will plug the spout, severe cases can damage the motor. Usually alkaline detergents were tested, there will be some rubber corrosive catalyst acceleratesOf the wiper strip hardening, hardening of the tape scratch windshield, it will accelerate the windshield surface is shaved scratches. If you replace the wiper, to pay the costs will be several times the price of a glass of water.
Some water instead of water glass risk is relatively small. However, important to note that the same ordinary tap water containing impurities, a long time, impurities may be attached to the inner rubber tube, affecting the normal water. Long-term use may cause increased friction between the surface of the glass and wipers, glass scratches. Master said cleaning water can simply dust, dirt adhering to the window, dead insects, and no ability to thoroughly cleaned.
window to paste insulation film
summer, a thin layer of insulation films can play a big role, not only can withstand the hot sun, but also heat, UV protection. Insiders pointed out that thermal insulation is one of the important reasons for consumers to choose the film, in addition, the light transmittance insulation film, UV index is content consumers must be concerned about. However, there are many many consumers buy for errors insulation film.
automotive insulation film having a divided front, rear and side wind wind the film of the film. Wherein the insulation film on the front windshield is the most demanding. In accordance with the provisions of the State Ministry of Public Security Traffic Safety regulations, transmittance of the front windscreen must be greater than 70 percentage so as not to affect traffic safety as a precondition. The most taboo attached to the front windshield dark window film. In addition, when selecting insulation film UV index, the higher the better, because it can protect the console components, and prevent premature aging long-term sun exposure.
side windshield insulation film aspect, likewise does not affect the observation mirror the premise owner. Alternatively the windshield side insulation film is more flexible, changeable color comparison. If the owners prefer bluish insulation film.
insulation effect color shades insulation film and not directly related, insulating film coating process is a key factor in determining the heat insulating effect. The higher rate of heat insulation film, the more powerful reflectors. If the car is equipped with GPS navigation systems, car owners should choose non-metallic film products currently on the market because most of the explosion-proof film is still a metal film, for GPS signal does cause interference.
on the glass insurance
risk of glass breakage alone, i.e., the insurance company liable insured vehicle during use, the vehicle alone and broken glass of a commercial insurance lossrisk. Alone and broken glass, only refers to breakage of the insured vehicle windshield and window glass (not including lamps, mirrors glass) appears. If the importing glass insurance rates, insurance companies, according to the price of imported glass compensation; If you choose China-made glass insurance rates, the insurance company for compensation according to the price of domestic glass. To buy car insurance on the glass, can effectively ensure the safety glass, the owner can be assured drove.
