There are many reasons for paint furniture pollution. Today, we mainly talk about the length of paint release time.
Paint is generally divided into three kinds: polyester paint, nitrocellulose paint and alkyd paint.
Polyester paint: polyester paint is mainly coated with polyester resin. The release of harmful substances is small and the smell is light. Relatively green.
Nitrocellulose coating: the main film of nitrocellulose coating is mainly nitrocellulose. It has good decorative effect, simple construction, fast drying, low requirements for painting environment, good hardness and brightness, and is not easy to appear paint film defects and easy to repair.
Alkyd paint: mainly composed of alkyd resin, it is the largest type of paint in China. The utility model has the advantages of low price, simple construction, low requirements for construction environment, full and hard coating, good weatherability and weatherability, good decoration and protection, etc.
Nitrocellulose paint and alkyd paint release harmful substances with heavy smell. Not as green as polyester paint.
Regular manufacturers of finished paint furniture are mostly polyester paint, pollution is light, the average paint smell about half a year is greatly reduced.
The paint used for decoration is mostly nitrocellulose paint or alkyd paint, so the smell of paint is big and the volatilization period is long. There is paint smell after two years of decoration.
The release time of coating is also related to the film thickness. If the paint film is thick, i.e. the amount of spraying is large, the release of harmful substances is large, and the release cycle is long, and the paint smell is heavy; if the paint film is thin, i.e. the amount of spraying is small, the release of harmful substances is small, and the release cycle is short, and the paint taste is light.
