first of all, when purchasing paint, you should choose a regular sales store, choose the products of well-known manufacturers, and see whether the paint meets the national mandatory standards. Consumers can buy products from well-known manufacturers sold in regular stores with confidence

secondly, we should carefully check the quality inspection report of the product, especially the VOC content in the quality inspection report. The national standard stipulates that the VOC limit is no more than 200 grams per liter, the better coating is less than 100 grams per liter, and the environmental protection coating is close to 0

if possible, ask the seller to open the paint bucket and test it by yourself. If there is serious stratification, the quality is poor; Stir gently with a stick. After lifting, the paint stays on the stick for a long time and covers evenly, indicating good quality; Twist gently with your hand. The more delicate, the better. Many domestic well-known brands of interior wall emulsion paint are mostly sold by opening the cover, which can make consumers intuitively feel its unique environmental protection

in addition, it should be noted that most non environmental friendly coatings have pungent odor due to excessive VOC, formaldehyde and other harmful substances, so we must be careful when choosing. Of course, don't buy products that smell very fragrant. Generally speaking, this kind of coating is added with essence, and the additive itself is a chemical product, which is difficult to ensure environmental protection. The coating with quality assurance will form a layer of silver ion and zinc ion protective film on the wall surface, which can inhibit the metabolism of bacteria attached to the wall and produce negative ions under photocatalytic conditions. The water molecules in the air collide with the negative ion materials in the paint through the gap of the polymer film, so as to increase the concentration of negative ions in the air and achieve the purpose of improving the living environment
