Experts pointed out that to judge whether the paint is a real green paint, attention must be paid to the three main points.
First, whether the paint meets the national mandatory standards, whether there is a Chinese environmental label certification.
Second, we must clearly see the quality inspection report of the product, especially the VOC content on the quality inspection report.
VOC is the abbreviation of volatile harmful substances. When the VOC content in the living room reaches a certain concentration, people will feel headache, nausea, vomiting, fatigue and other symptoms. Serious coma will also occur, and it will hurt people's liver and kidneys. nervous system. In the national standard, the VOC limit is no more than 200 grams per liter, and the better paint is below 100 grams per liter. The truly environmentally friendly paint is close to zero.
The third is to pay attention to the brand when purchasing, it is best to select the products produced by well-known large enterprises. Also observe the corrosion of the joints of the iron barrels, see if the signs on the iron barrels are complete; the imported products should also see if there is any Chinese description.
