To make a correct and relaxed driving is important to have a good visibility.
Problems like glass wear, impacts and prevent chipping have adequate perception. Some of these damages are solved by repairing the glass surface with the use of new technologies.
The cars leave the terminal with laminated windscreen made of two layers of glass house inside a plastic sheet. When impacted, it absorbs energy, thus it is called up.
However, if the glass is hit a mark or cracking may occur. There begins to damage the windshield and breaks much more if exposed to a sudden temperature change or is subjected to strong vibration.
The most sensitive area of a windshield crack is located near the edges (10 cm band around them), since a small sliver can become a crack; is slit to the edge first and then towards the center, motion transmitting body.
Among the most frequent damage there are two large groups according to the form they take on the crystal surface: porthole, circular shapes, and star.
How is repaired
There are several ways to make the settlement of the windshield. One is done with computerized machines that determine the type of stroke, as well as remove all traces of broken glass and dirt that has been admitted to the outer layer of the windshield. Then injected into the hole left by the punch a resin having the same optical and strength characteristics than glass.
This product is forged with ultraviolet light and is recovered between 80 and 95% glass aesthetics. Due to the pressure of the machine, the liquid access to the ends and at the end the area is covered with a sheet that is dried and solidified to give the glass an appearance of original part.
Another process is manual, from the point of impact pierces the first layer of glass with a lathe without touching the plastic, then the air is extracted content with a tool that makes vacuum on the break and the resin is injected.
When there are long cracks a tool that presses from within the glass and opened a cut on the surface is used. With an applicator, the crack is filled; by capillarity, viscous liquid column is displacing air. No additional holes are made to fill the cut, preserving the aesthetics.
It is advisable that the repair is made immediately after the blow suffered since the break grows over time, and inside particles of dirt, dust and soot, which are more costly.
The value depends on the damage repair; on impacts, can cost between 30 and 60 dollars, and if the cracks between 120 and 150 dollars.
Intensive care: immediate care to ensure working
Immediately following the settlement note:
- Do not use the air conditioning or heating for 24 hours, since temperature differences can occur with the outside and crack the glass.
- Leave the windows open slightly to allow entry of outside air.
- Wash the windshield after 24 hours.
- Try not circular stones or irregular terrain.
- If possible, leave the car in the open air to accelerate the drying of the resin.
