Frequent smog, people have seen the seriousness of urban air pollution, but other pollution around them is easily overlooked. Furniture, flooring, lighting, glass, paint, etc., which are needed in home decoration, may cause a certain degree of pollution if improperly purchased. Tiles, lighting and coatings not only cause air pollution in the indoor environment, but also cause light pollution, which has an important impact on human health. Paint professionals remind everyone that in order to prevent home pollution, ceramic tiles and coatings must be properly selected. However, the market environment is complex, counterfeit and shoddy products are not uncommon. Purchasing home improvement materials must be eye-catching and careful. When decorating a home, it is recommended to choose a tile with a small reflection coefficient. Due to the strong reflection of white and metallic tiles, it is not suitable for large-area applications. The study and children's rooms consider replacing the floor tiles with wooden floors. If bright polished tiles are installed, light lights should be turned on to minimize light pollution. There are certain restrictions on the purchase of paints. Because light paints have less impact on vision, you can use beige, light yellow, etc. instead of glare white paint to paint the walls to reduce the high-brightness reflected light. In addition, the purchase of brand-friendly environmentally friendly low-carbon paint can minimize the risk. According to the Nanfang Daily, the results of the spot inspection by the Quality Supervision Bureau revealed that there were 17 batches of industrial coatings, automotive coatings, floor coatings, powder coatings and marine coating products produced by Guangdong enterprises. The unqualified product discovery rate was 11.3%. A batch of Clivia brand NC Tianna water produced by Zhongshan Hengbao Chemical Co., Ltd., the “gelling number†project is not up to standard; a batch of Chuangmei brand rust-proof iron red (paint) produced by Foshan Nanhai Yinghong Chemical Co., Ltd. ), fineness, drying time, gloss project is not up to standard; a batch of Opels outdoor powder produced by Opels Plastic Powder Co., Ltd. in Shunde District, Foshan City is not qualified. According to the person in charge of the paint, many of the fake and inferior paints on the market are under the banner of foreign brands and big brands. Therefore, in addition to looking at the brand, you should also learn to distinguish the authenticity of the brand products. When purchasing paint, be cautious.
