In today's society, there are many car lovers. Everyone cares about the various parts of the vehicle. However, many people ignore the maintenance of glass. Although the car glass does not need to be replaced regularly like some wearing parts, it is especially important to check regularly and repair after the damage.
Type of car glass: At present, the glass on the car is mainly divided into two materials, laminated glass and tempered glass.
Laminated glass is a layer of colloidal film between the two layers of glass that does not completely crack and spread when damage occurs. Even in the event of a severe impact, relying on the middle of the adhesive film can ensure that the glass will not fall off and partially scatter under severe damage, and still maintain relative integrity. Because of this characteristic, laminated glass is required to be used on the front windshield in order to ensure that the driver is allowed to achieve complete and safety as much as possible after the impact.
After being damaged, tempered glass will quickly diffuse into numerous small particles, and it is easy to fall off. It can be easily escaped in a critical situation, and the probability of stone impact on the side and back of the car is less than that of the front windshield. Therefore, tempered glass is widely used in Other than the front windshield.
Only the windshield can be replenished: Based on the above mentioned characteristics, the windshield used in the front windshield of the current model is laminated glass, and cracks can be repaired.
In addition to the front block, the tempered glass at the surrounding windows will quickly spread or even fall off due to damage, so it cannot be repaired. So the so-called glass repair is for the front windshield service.
What kind of crack is recommended to be repaired: Under normal circumstances, the damage caused by glass is nothing more than the pebbles rolled up by the high-speed driving. Although the stones are not big, but the speed is fast and the shape is irregular, the glass can often be shot out of the pieces in an instant. .
However, the range of cracks cracked by pebbles is usually small, and the diameter will generally be about 5mm. In this case, the owner should go to a professional maintenance store for glass repair as soon as possible. The earlier the time. However, if the main body of the damage exceeds 20mm, the repair effect will be poor, and the general store will recommend replacing the glass.
Isn’t the glass that is not recommended for repair really repaired?
Many friends will ask, a windshield is usually not low value, many people do not insure the glass alone to break the risk, a little larger damage is recommended to replace it is not too wasteful, if I will use it?
In fact, beyond the range of 20mm, as long as it is not exaggerated, it can be repaired, but the strength after repair can not be guaranteed. When the high-speed wind resistance is increased, or the car wash, rain, snow, sand and other windshields are frequently stressed, The strength of the glass is not guaranteed, and there are certain safety hazards. Here, our suggestion is not to repair more than 2cm, replace the new windshield as soon as possible, to avoid the use of glass to produce larger cracks.
What kind of damage is easy to repair
Since the damage is caused by the rolled up stones, the damage area is generally not large, but since the surface of the stone is irregular and the impact trajectory is not regular, the shape of the damage point is various. According to the professional, if the broken part shows a round outline, the damage is easier to repair and the repair effect is good, because the round broken contour can support the surrounding complete glass, compared with those that spread a lot of cracks. For wounds, it is easier to be repaired.
What happens if you don’t fix it?
Usually the glass breaks, the maintenance staff will recommend repairing as soon as possible, many friends will ask, since the wound has appeared, simply do it, and have time to repair it. In fact, this method is not correct. With the change of temperature during the day, the deformation of the glass will cause deformation of the glass, and the continued wind resistance will further erode the damage, and it will continue to bring pressure, and the damage may be amplified. If you miss the area of ​​the best repair, the repair effect will be greatly reduced, so it is recommended to find that the window is broken and should be repaired as soon as possible.
Is there any trace after repair?
Many friends will care, the broken points are clearly visible, and where can the repair be done? Through our personal experience, the damage that meets the best repair range, through professional maintenance, can reduce the irregular damage to a The white glue spots are definitely visible to the naked eye, but they are almost negligible.
Diligent inspection: In daily life, glass is fragile, and glassware in the home must be extra careful. However, many people use the car glass, because they know that their strength is high, they will not be easily broken. In the long run, the protection of the glass will be taken lightly. In fact, the car glass is also fragile. It is necessary to check frequently. It is necessary to carry out the damage in time. deal with.
Glass repair trouble? In order to better display the effect, we found a worn windshield. In actual operation, the glass repair does not need to remove the windshield. The whole repair time is about half an hour.
Glass repair expensive: due to the difference in technology, all kinds of glue are also varied, there is no relatively uniform price suggestion on the market, tens to hundreds of dollars are possible, relatively regular repair shop repair glass is generally 200 yuan Even higher.
Is there a time limit for glass repair? There has been a saying that the glass is damaged and repaired within a certain period of time. After this period of time, it cannot be repaired. We also consulted relevant experts. When the glass is damaged, it should be repaired as soon as possible, otherwise the wound will gradually expand, and some dirt will also enter the wound, affecting the repair effect. However, there is no strict time limit at present, and more is based on the wound condition during maintenance, so it is necessary to find the problem as soon as possible.
Be careful when changing the wiper: The staff in the store introduced that many of the owners who came to repair the glass were accidentally smashing the glass when cleaning the wiper themselves, so everyone should take extra care when checking the wiper blades to avoid scratching the glass. Happening.
Insured glass insurance: Some friends think that glass is not as easy to scratch or even damage as the body, so it will not buy special glass insurance, but here I still recommend that you buy this insurance, ready, in case the glass is If you break down, don't you use it?
There are many parts in the car. Everyone is accustomed to paying attention to those aspects that are directly related to driving safety, but ignores the maintenance and inspection of the glass. In fact, the window is one of the important parts of the vehicle, and it is of equal importance to the safety of driving. Therefore, it is very important to check the window.
Commonly used distance measurement methods include tape measure distance and photoelectric distance measurement. The measuring distance of a tape measure is measured along the ground using a tape-like ruler that can be rolled up, which is a direct measuring distance. Photoelectric ranging is to use an instrument to transmit and receive modulated light waves between two points, and measure the distance according to its propagation speed and time. It belongs to electronic physical ranging. Photoelectric ranging is indirect ranging.
