There are too many reasons for the yellowing of profiles, and the basic common problems of plastic steel profiles are now, so it is very difficult to deal with. Generally speaking, if it's not particularly serious, it's pretty much the same.

The main parts of yellowing: the first and second floors near the street, near the air conditioner, etc., where there is a heat source. And it is generally caused by the dispersion of particles, which leads to the decomposition of the profile surface. As a result, it is very laborious to deal with.

If yellowing is not common, individual locations in individual places, need to be treated, generally is the surface decomposition of the profile generated near the heat source. You can polish the surface with fine sand, just polish the yellowed area. However, it must be noted that after the general profile is used for a period of time, it is basically not the original color, so your polishing must be slow, otherwise the surface of the profile will be scratched.

Yellowing is also divided into 3 cases.

The first is to use chemicals to clean plastic steel doors and windows, because the chemical agents react with the doors and windows, so that the surface of plastic steel doors and windows is yellow.

The second is the cause of dust. Just clean it and you're good to go.

The third is the reason for the profile formula, and it is also the most common phenomenon, this kind of yellowing is generally called aging. If the plastic steel window is partially yellow and part is not yellow, it means that the window profile formula is uneven and the quality is poor, and the first-class door and window products should be the overall gradual discoloration. Sunlight only ultraviolet rays will decompose the plastic steel door and window materials.

Therefore, some materials of stabilizers or ultraviolet absorbers should be added to the plastic steel profiles to prevent the doors and windows from aging too quickly. At present, the market is fiercely competitive with plastic steel profiles, some small factories in order to sell, simply do not add additives to prevent ultraviolet rays in the material, and stabilizers also use relatively low-grade products, resulting in doors and windows on the wall, less than a year, the situation of yellowing occurs, there is no way to recover, or you paint some color on it?
