In Russia, there are hardly any amateur autoenthusiasts who have never experienced cracks in the windshield. Although the problem is quite common, few know that in most cases, the replacement of the windshield is an alternative to expensive replacements. Where are the cracks in the windshield coming from?
Where are the cracks in the windshield coming from?
To begin with, it is worth noting that the windshield, or as it is sometimes called, the windshield is very different from the rest. Side and rear glazing are usually single-layer, hardened. The impact of the attack is on many smaller shacks. This is done for safety, so that in the event of an accident, not to traumatize the driver and passengers.
An ordinary windshield consists of three layers. There is a plastic layer in the middle, and the interior is made of glass. This is done to make the windshield strong. It is, above all, one of the superpower elements of the body. But the main function of this windshield design is defensive. For example, if a stone is hit, it is not broken as a side or back, but it is just cracking.
In many countries, there are certain standards that determine whether the replacement of the windscreen is possible or necessary
By the way, the main cause of the appearance of bevels and cracks in the windshield is the entry of stones from the wheels of the associated or oncoming transport. The second place is a temperature drop. Usually the cracks are formed in the cold when the motorists, so as to quickly melt the ice on the windshield, the maximum includes the heater and direct the airflow to the glass. Such cracks tend to be long and are located in the lower part of the windscreen.
The replacement of the broken glass is expensive, especially if it is thermal or heated. In this case, the alternative is to repair it. True, if the cracks are large or too many, the specialists may recommend replacement, because the amount of recovery may be close to the cost of the new glass. It is not worth forgetting that large cracks, even after repairs, weaken the glass. Therefore, in many countries there are certain standards that determine whether repair is possible or is necessary to replace the windscreen. For example, in the US, the length of the crack is the measure: repair is allowed if it is not more than 6 centimeters.
How to repair the cracks in the windshield
The first thing to do with the appearance of bevels or cracks is to reliably isolate them from the dirt. It is enough to put a piece of transparent scotch on the damaged portion to the crack or to the extent of the dust. The less it is in the damaged section, the higher the quality will be repaired.
The simplest and cheapest operation is the repair of a simple, free rift. To do this, the service flushes the glass and, with the help of a special injector, introduces a liquid polymer which, under pressure, fills out the glass. The injector is then removed and taped to the damaged portion of the film to ensure that the polymer is not forced out. The repair will then be dried by a UV lamp. The final phase is the removal of the film and the surplus polymer by means of the blade and polishing of the repaired area.
With cracks, the process becomes more complicated. You must first stop the possibility of further distribution. For this service, the Services using a rough diamond or hard-smooth drill are drilling down small holes at the very end of the crack. This is done to remove the voltage at this point in the glass.
Then a liquid polymer is injected into the crack with the help of the injector, which fills it in its entirety. Further operations are identical to the repair of bevels.
According to Russian legislation, the cracking of the windshield is permitted only on the passenger's side.
In principle, small cracks and how to repair themselves, repair kits are sold in almost any major spare parts store. However, in the absence of experience and skills, the result may be different from what is expected. Therefore, independent repair of cracking of the windshield can only be carried out at its own risk.
Why repair the cracks in the windshield?
According to the Russian legislation, the cracking of the windscreen is permitted only on the passenger side. If the fracture is in the driver's wiper area, it must be repaired or replaced as a whole. It is not forbidden to ride with such a crack, but it is not legal to pass a technical inspection.
But that's not the point. First of all, the rift shacks, obstructs the review, and at night refractive the headlights of the oncoming car. This is not the best way for us to be safe.
It should also be remembered that if you have scheduled a trip to Western Europe, the "wound" on the windshield will not be empty. Therefore, if the windshield of your car has even small cracks, take care of them in advance.
The alternative of repair of complex fractures or skulls is to replace the windshield on a Russian or Chinese analogue. But a lot of people are against it. The fact is that for the most part these analogues are inferior to the originals, except for prices. They are quicker to wiper the wiper blade wiper, do not have sufficient strength, and are worse off against any new cracks.
