Anonymous users2024-01-24Yellowing of paint is a very headache, affecting the aesthetics of the room, and it is not easy to maintain. The main causes of yellowing are the following;
Latex paint: When latex paint and TDI-containing paint are cross-constructed, a chemical reaction will occur when the high content of free TDI and latex paint meet, causing the wall to turn yellow.
Oil-based paint: The main cause of yellowing is due to the change of unsaturated bond structure, oxidation or chemical bond breakage in the paint resin due to ultraviolet irradiation in the light, and this change is reflected on the outside is the yellowing of the paint film.
White paint: In order to eliminate the color difference of the board when making the plate, the manufacturer often bleaches the board, and the bleach agent mainly uses hydrogen peroxide, sodium chlorite or sodium bisulfite. In addition, some manufacturers pass off the bleached material as a good material, and when the polyester white paint is combined with the bleached wood, the curing agent TDI of the polyester white paint reacts with the oxidized bleach residue left in the wood during bleaching, causing the surface of the paint film to turn yellow immediately.
White furniture is more than a year, it will turn yellow, and if it turns yellow, wipe it with toothpaste to remove the yellow one.
Yes, it may turn yellow after alcohol disinfection. It is best not to use alcohol, and after washing, it is best to expose it to the hot sun.
It may be a problem with the backwater, or it may be that there is something unclean in the refill.
What I understand is that after a long time, the white paint on the surface will be damaged, and the dust will accumulate over time, and it will turn yellow.
