The headlight glass should not be scratched, how can there be scratches

The material of glass is made up of three main parts: the basic raw material, the flux and the colorant, as well as the decolorizer, the clarifier and the emulsion.

The basic raw material for glass making.

Silica is the most important raw material for glass production. The reserves of silica on the earth are very large. Silica is the main raw material for stone and the main raw material for making glass.

The silicon content of different stones is different. These materials are the most common in our lives.

flux. The melting point of silica is very high, and it is very limited to achieve this honor. The ancients tried to add some other substances, and when it melted, the temperature became lower.

In addition, the silica melts very abruptly, and there is no filter transition stage that gradually softens during the heating process, and after fusing some other substances, the glass can be in various glorious states at different temperatures, and the glass can be effectively shaped and shaped. This substance is the flux.

The flux is usually a raw material containing sodium oxide, potassium oxide, lead oxide, calcium oxide, barium oxide and other substances, such as limestone, feldspar, soda ash, boric acid, lead compounds, and barium compounds. (Sodium oxide can reduce the viscosity in the formation of glass, make the glass easy to melt, and play a good role in fluxing; Barium oxide plays a fundamental role with sodium oxide in the formation of glass; Tin oxide can increase the chemical stability and mechanical strength of glass; Lead oxide can increase density, improve serpentine, and have a special luster; Lead can make the glass have a large refractive index to light and a small scattering rate, making the glass more shiny and stable.

Clarifier. Some bubbles will appear in the process of making glass, and the clarifier used to reduce these bubbles is used. The main commonly used are arsenic oxide, antimony oxide and nitrate.

Emulsion. In the production of glass, the artist makes the glass opaque according to the requirements of the work, and the emulsion is the emulsion that makes the glass opaque. It can cause glass to produce crystalline or unfixed colloidal particles that differ from the refractive index of the glass itself to produce an opaque effect.

Commonly used emulsions are tin oxide, antimony oxide, and phosphate.

Decolorizing agent. The head colorant is mainly used to eliminate the undesirable color brought by the impurities in the raw materials to the glass, so that the glass city is colorless and transparent. There are two main types of chemical decolorizing agents and physical decolorizing agents, and chemical decolorizing agents usually disappear through oxidation, mainly sodium nitrate and potassium nitrate.

Physical decolorizers make glass colorless by producing complementary colors, mainly manganese dioxide, selenium and cobalt oxide, and bromine oxide.

Hello, have you not** look at the scratches.

Look at the depth of the crack, the smaller one can be repaired with special watering, if it is just a scratch, polishing and repairing it.

If it's deeper. If there will be water seepage, it is recommended to buy a shell to package it, otherwise it will not be good if the water seeps.

Hello, no, the lights will be affected, I hope my answer can help you, I wish you a happy car!! If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

It is best not to use glue Cracks are easy to enter the water, affecting the electrical circuit, and the gains outweigh the losses.

Hello, you can try it first, I hope my answer can help you, if you don't understand something, you can continue to ask me! Have a great day! If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Polishing can achieve results, but I don't think anyone can do it with the technology, so I recommend buying a new headlight, or just using it well!

Mainly you have no tools, 1000 mesh sandpaper, sander, polishing liquid, wool balls. (The wool ball is glued to the grinder for use).

First of all, use sandpaper to smooth the scratches, apply polishing liquid and polish it with wool balls, then apply polishing liquid and polish it again, and after two or three times, it will be the same as new.

In general, it is not recommended that you do this yourself, there is no need for that, if it is a problem after maintenance, you can directly find a maintenance worker to deal with it for you.

Hello, a lot of headlights are like this, just decorative.

That's nice to decorate, and the A6L headlights have that stuff too.

Hello, can you send **.

Hello, this can't be repaired, but it can be glued with glass to keep it from leaking.

Is it on the bumper or the lampshade is cracked.

It can be repaired, but it depends on the length of the glass crack, if the length is too long, it cannot be repaired.

Windshield repair refers to the windshield being hit by stones or other objects, resulting in small dents. Special glass repair agents can be used to fill in without affecting the original glass structure and use.

It is not recommended to repair the length of the crack, and the repair effect is quite limited.

No, 502 is also corrosive to glass.

Automobile glass is a kind of double-layer glued glass, when hit by external force, if the force is not enough to make it break and only produce cracks, the middle glued layer will be separated due to the action of air entry and atmospheric pressure, if you continue to drive, the crack area will expand more and more, affecting the line of sight and driving safety. Automotive glass repair is aimed at treating glass cracks or small wounds, and the operation time is short, and it will not affect the daily use of the car.

The repair of automobile glass is mainly to fill the cracks with liquid gum and eliminate the gaps. The material used to fill the glass is a liquid gum with high transparency, which can be quickly solidified by ultraviolet heating, and the strength can reach more than 90% of the original glass. The construction process is not very complicated, the main tool is a vacuum syringe with a needle-like structure, the function of which is to remove the air from the glass wound and then fill it with a glass repair agent (liquid gum).

After repeated pumping and compression, at least 90% of the repaired space will be filled with filling solution, and then irradiate the repair solution with ultraviolet lamps for two minutes to solidify the repair solution. After the machine is removed, there will be a small gap in the center of the wound, at this time, a higher concentration of repair agent is dropped, covered with a glass piece, and dried with the same ultraviolet lamp, the surface is scraped flat with a blade, coated with polishing agent, and polished with a cloth.

Usually a round wound will only have a small circular mark or spider-like crack after the repair is completed; The long crack will only leave a faint line, and only at a certain reflective angle can the traces of repair be seen, and the general view is still a "seamless" good glass. Moreover, the strength of the repair can be guaranteed, and the strength of the hardened colloidal glass can reach more than 90% of the original glass.

Repairs are not something that can be done with any damage, once the glass has broken apart, or broken into pieces, it is irreparable. And if the crack is too large, the repair cost may be comparable to that of a new piece of glass, not to mention the scar. Therefore, it is best to use the repair of automobile glass in the case of small damage to save time and money.

Precautions. Many people have experienced that the windshield has been bounced by stones or other hard objects when driving at high speeds. In this case, if you replace the whole piece of glass for a small crack, it is not only wasteful, but also really not worth it; If left unchecked, the wind pressure will make the cracks bigger and bigger, which will not only affect the appearance, but also pose a threat to safety.

, It doesn't work if you use it, you can use the glass to turn it, just take an eye, and only the outer layer of glass will not be breathable. The front windshield of the sedan is both two-layered.

OK. Car headlights, also known as car headlights, car LED daytime running lights, as the eyes of the car, are not only related to the external image of a car owner, but also closely related to safe driving at night or in bad weather conditions. The use and maintenance of car lights cannot be ignored.

It is said that the first car headlights were domestic portable lights. In 1887, when a driver got lost in the dark wilderness, a farmer used a portable lamp to lure him home.

Car headlight features:

1. The color temperature is high, and the light color is blue.

It looks more handsome. K is the indicator of the K number, and the color temperature of the general halogen lamp is below 3000. Xenon lamps generally start at 4500K.

7000k is ordinary. Two days ago, I saw a buddy who said that there was a 12000k xenon lamp, and I was crazy, and it must have turned purple blue. The K number is high, which is generally closer to daylight and easier to accept, but I think the real benefit of a high color temperature is just that it looks good, and nothing else has much effect.

2. High brightness.

Note that color temperature and brightness are fundamentally different concepts, and xenon lamps are not lit because of the high color temperature, but because of the high brightness. The unit of brightness is lumens, and the number of lumens of xenon lamps is generally 3 times that of ordinary halogen lamps.

The installation holes of the headlights are mostly long holes, which have the conditions for fine-tuning, but if the gap is too large or there has been an accident, the installation holes alone cannot be adjusted to the ideal state, so the sheet metal needs to be adjusted appropriately to ensure that the gap between the headlights and the fenders, hoods and bumpers reaches the best state

The headlight gap of the car can be adjusted, the headlight height can be adjusted, and you can also adjust it, and you will find a screw fastening that one side of the air intake grille below.

This is an incomplete repair after an accident;

If all the original spare parts are used, they can be adjusted, if they can't be adjusted, there are parts that are not completely repaired, and the fixed position of the headlights or the fixed position of the bumper will produce displacement (deviation), and it can not be adjusted directly when installed. To put it simply, the foundation has not been repaired well.

Hello, because there is a slight gap between the original parts and the replacement parts, even if it is the original factory, after the replacement, it is normal that there will be a gap, and it is unlikely that 4mm is possible, it is recommended to check whether the accessories are original.

Prove that the sheet metal of the 4S shop is not in place! In general, it is possible to make adjustments! It is recommended not to go! 4S stores are making money and don't care! You'd better find a sheet metal master to take a look! Dry sheet metal will definitely do.

It's impossible, you can add your own seals.
