automotive glass repair - this is probably one of the most popular services at the station.This is not surprising, since this part of the machine is the most vulnerable to damage.Most often, it is exposed to a variety of small stones, which are emitted from the wheels of an oncoming car.Also, chips, cracks on the windshield can occur due to high temperature differences.For example, if the street -30, and you include the heater on full power.In any of these cases, an urgent need to go to the service station for repairs.In today's article we will discuss how to stop the crack on the windshield and why repair is more profitable than a complete replacement.
design features
To begin, we note that the wind element is very different from their side "brothers."The fact that the side and rear windows are a type of single-layer (Stalin), but because when struck suddenly crumble into many pieces.Front glass - a triplex.It consists of several layers of coatings (usually three).In the middle is a plastic element, and on the sides - from the outside and the inside - is coated with glass.This is done to give the member a higher strength.The main function of such a design - protection, as in contact with the surface of stone or other object, it does not disintegrate into a plurality of particles and a crack.
Cracks and law
Under Russian law, such deformations as cracks and chips are allowed only on the passenger side.If the defect is located in the driver's wiper operation, it is necessary to repair or replace the entire windshield.Of course, for such a failure you will not be fined, but to pass inspection with her you just do not succeed.
But the troubles did not end with cracks.The fact that this strain has a property blikovat, especially on a bright sunny day.And at night, it refracts headlights of oncoming cars, thereby distracting you from the path and obstructed the normal review.
Also note that in Western European countries is strictly forbidden to leave with chips and cracks, even if they are from the passenger seat.
repair or replacement?
Replace cracked glass is not cheap.This is especially true athermal elements and details of heating.It is worth noting that the purchase of this item is very easy to confuse the original with a fake.Replacing the original cracked glass on the Chinese equivalent is dangerous because it is less protected from damage and is more vulnerable to scratches that can be formed at the first wash.
But it all depends on the degree of damage.Substitution is meaningful only if the area is too large damage.If it is chipped, cracked windshield, the most reasonable to repair it.First, it is cheaper, and secondly, you have preserved the original windscreen.
By the way, in the United States is the main indicator of the repair the crack length.If she is more than 6 centimeters, this glass must be replaced.
How to stop the crack on the windshield?Repair technology
This process is very time-consuming, so it is not recommended to do with their hands.Below we describe the details of technology of repair and restore the damaged windshield.
So, initially the surface is cleaned of dust, dirt and grease.Next, the damaged area of glass is glued special piece of Scotch tape.Through a crack in it will not be engraved dust.
most simple repairs - is the restoration of chipped glass.To do this, the service station clean the surface of the sediments by means of the injector and injected into the liquid polymer.Last its composition under pressure fills chips.Further, the injector is removed, and the damaged area of glass glued to a piece of film.This is to ensure that the polymer is not leaked outside.Then the surface is dried, which is made using a UV lamp.At the end of repair and recovery process deletes all the excess film and the polymer with a sharp blade.After that, specialists produce polishing the site remediation.At this all ends.
Regarding the cracks, then with them, things are different.Remove this type of damage is very difficult.This requires a lot of experience, skill and special tools.The essence of the restoration work is to use a special diamond drill.With this tool, you can Drill crack on the windshield, having made small holes in the end of it.This is to reduce the stress in the current point on the surface of the element.
Price
repair How much does a repair cracks on the windshield?Price recovery operations depends on the type and size of the lesions.The cheapest is the removal of chips (from 600 rubles).Repair cracks expensive.For every centimeter has to pay 50 rubles.At first glance, the amount is small.However, if this "strip" stretched around the perimeter of the glass, which is more than half a meter, repair of cracks on the windshield and could reach 2.5 thousand rubles.Stop the development of this strain can be for 400 rubles.Trim the edges of the cracked windshield costs about 200 rubles.

Where to drill the glass?This should be done once a crack, pre-defined layer, which has been engaged.Depending on whether it is an external or internal, drill the crack from the street or the interior.When affected all layers, a hole was drilled through.
Next sticking glass defects obscuring polymer composition.Note that there are two types of glue.This liquid polymer (for microcracks) and thick.Last suitable for plugging holes by drilling.In the next step the surface is subjected to polishing.For starters, she carefully washed, then treated with a special compound (this can be quartz sand and fine-grained sandpaper).Then the glass is polished by means of nozzles.The latter should have a different degree of abrasiveness.Through this method, it can be restored to 95 percent of the initial transparent glass.On this question of "how to stop the crack on the windshield with his hands" can be considered closed.However, remember that this method can be applied only if the particular expertise and tools.Otherwise, the result will disappoint you.
