How to deal with chrome oxidation of front car exterior trim plate
The methods to deal with chrome oxidation on automotive front exterior trim panels include the use of hydrochloric acid, toothpaste, carburetor cleaner, toilet cleaner, copper rub paste, anti-rust agent and repair by professional vacuum plating equipment. The specific method can be selected according to the degree of oxidation and available resources:
Use hydrochloric acid : Pour hydrochloric acid on a rag, then wipe the spots, clean with running water after cleaning. This method is suitable for heavy oxidation situations, but it needs to be safe when used.
Use toothpaste : toothpaste has an abrasive effect and is effective for cleaning light rust, but not as effective for deeper spots. When using toothpaste, you can dip a wet towel into the toothpaste and gently wipe the oxidized area.
Use carburetor cleaner : This cleaner is the most effective, but be careful not to drip onto the paint, so as not to cause corrosion. When using carburetor cleaner, spray it on the oxidized area and let it sit for about ten minutes before erasing.
Use the toilet cleaner : The toilet cleaner contains dilute hydrochloric acid to dilute the oxide. Pour it on a towel and wipe gently. The toilet cleaner is corrosive to some extent, and after wiping, it is necessary to wipe off the residual acid with a clean wet towel.
Use copper paste : copper paste has a very good effect on the removal of rust on metal materials. Gently apply copper paste on the oxidized place with a damp rag.
Use anti-rust agent : such as WD-40 universal anti-rust agent, the metal surface will form a thin dense protective film after use, to isolate moisture and air.
vacuum electroplating repair : go to 4S shop or repair shop to use professional equipment for electroplating repair of oxidation, you can re chrome on the surface of the bright strip, and you can change the color according to demand.
Choosing the right method for processing can make the front door trim panel of the car more beautiful. It should be noted that when using any cleaning agent, it must be cleaned with tap water after cleaning, so as to avoid the impact of residue on the car paint .
The front exterior decorative plate is an exterior decorative plate at the lower part of the automobile door. It is attached to the sheet metal through fasteners. The edge of the exterior decorative plate is attached to the sheet metal and secured by double-sided adhesive bonding. This part is located on the outside of the door, mainly plays a decorative and protective role, but also a part of the appearance of the vehicle, affecting the exterior design and style of the vehicle. In addition, the door trim panel (including the front door trim panel) plays an important role in the automobile design, they not only play a decorative and shielding role, beautify the interior space, improve the beauty and comfort of the vehicle, but also have the actual protection function, protect the internal structure of the door from the external environment and daily use .
The car exterior also includes other important components, such as the front bumper, rear bumper, body skirt, outer circumference, etc., which together constitute the appearance of the vehicle, not only providing structural support, but also affecting the streamlined design and safety of the vehicle. As a part of it, the front door trim plate, together with these components, jointly shapes the overall image of the vehicle, showing the design philosophy and craft level of the vehicle .
B-pillar exterior trim plate, also known as B-pillar door trim plate
1, most plastics are light, chemically stable, and will not rust.
2, good impact resistance.
3, with good transparency and wear resistance.
4, good insulation, low thermal conductivity.
5, general formability, good coloring, low processing cost.
6, most of the plastic heat resistance is poor, thermal expansion rate is large, easy to burn.
7, dimensional stability is poor, easy to deformation.
8. Most plastics have poor low temperature resistance and become brittle at low temperatures.
Plastics can be divided into two categories of thermosetting and thermal plasticity, the former cannot be reshaped and used, the latter can be repeatedly produced.
There are basically two types of plastic polymer structure:
The first is linear structure, and the polymer compound with this structure is called linear polymer compound;
The second is the body type structure, and the polymer combination with this structure is called the body type polymer compound.
Some polymers with branch chains, called branched-chain polymers, belong to the linear structure. Although some polymers have cross-links between molecules, they are less cross-linked, which is called a network structure and belongs to a body type structure.
Two different structures, showing two opposite properties. Linear structure (including branched chain structure) polymer due to the existence of independent molecules, it has elasticity, plasticity, can be dissolved in solvents, heating can melt, hardness and brittleness of the characteristics of small.
How to solve the abnormal sound of the car door panel?
It is normal for the door panel to ring abnormally after the car has been used for a long time. Often driving on some bumpy roads, the interior panel of the car will appear some open, which will produce some abnormal sound. The interior panels of the car are fixed with clips, and the interior panels will become loose when driving on the bumpy road, so that the interior panels will appear abnormal. When the interior panel of the vehicle needs to be removed for maintenance, be sure not to break the clip. If the clip is broken, then the interior plate will not be fixed properly, and there will be an abnormal sound. The solution to the abnormal noise of the door panel is as follows:
1. Check whether the clip is loose
First, we need to check whether the clamp on the door panel is loose. If the clip is loose, it will cause abnormal sound in the interior panel. We can use a screwdriver or similar tool to secure the clip in place to ensure that the trim board does not come loose. If the clip is damaged, replace it with a new clip.
2. Replace the interior panel
If there is no problem with the clip, then there may be a problem with the interior plate itself. At this point, you need to replace the interior panel. When replacing the interior panel, remove the original interior panel and install the new one. It should be noted that the clip must be fixed during installation to ensure that the interior panel will not be loose.
In short, the abnormal noise of the door panel is a common problem, but it is also simple to solve. Just check if the clip is loose, or replace the interior panel. If you encounter the problem of abnormal ringing of the door panel, do not panic, you can solve it yourself.
