At the furniture fair in March this year, some home furnishing companies made a very eye-catching brand - no formaldehyde. Among them, the "electrostatic dusting" technology instead of paint and the PP material instead of PVC are the most concerned.
Paint & PVC
Two large formaldehyde households
Paints contain harmful volatiles, which most people know. At least the amount of harmful gases can be clearly seen on the wall paint box purchased from the home decoration. However, as long as the hazardous substances are within the standards set by the state, they are basically safe. At present, the technology of the paint industry is quite mature. The net paint and full-effect paint of many big brands on the market can control the release of harmful gases within the scope of national standards, even far below the national standards.
Another paint-consuming household in the home is a furniture paint that few people pay attention to. In the home store, many furniture stores claim that their products are brushed "varnish." But have you discovered that the varnishes that have been popular in recent years are almost all on solid wood furniture, and on some colorful furniture, especially children's furniture, a lot of paint is used.
PVC is a commonly used product in home life, and the application of PVC veneer in cabinets, wardrobes, and panel furniture is also quite frequent. Although this material has many advantages such as low cost, good processing performance, non-flammability, and good weather resistance, however, PVC has added toxic additives and plasticizers in the production process. Non-standard products may ooze or vaporize these toxic substances. Some PVC materials also contain heavy metals such as lead and cadmium, which may affect the reproductive function of the human body and increase the risk of cancer in the human body.
Electrostatic dusting
Solid "paint", recyclable
During the furniture fair in March, several brands introduced electrostatic powder spraying technology. The new Express reporter saw at the Jisheng Weibang Purchasing Conference that Ruixin Furniture from Hong Kong introduced children's furniture made by electrostatic powder spraying technology. At the Guangzhou Furniture Fair, Zhaosheng Furniture also applied this technology to office furniture. Above.
The core brands of Ruixin and Zhaosheng are responsible for introducing to the New Express reporter that electrostatic powder spraying is a new technology. The principle is to use high-voltage static electricity to spray the resin on the surface of the board to form a protective film. This protective film itself is environmentally safe. In addition, the protective film can also seal the surface of the board to prevent it from releasing harmful objects.
This new type of "solid paint" can replace liquid furniture paint. It is characterized by not releasing harmful gases such as formaldehyde, and it can be recycled and reused. At the same time, it can produce rich and full color and can spray any pattern, which is very suitable. Used in children's furniture.
The reporter saw at the exhibition that Zhaosheng Furniture immersed the material in a fish tank to demonstrate its environmental friendliness; at the booth of Ruixin Furniture, personalized photos were painted on the furniture to show its powerful function. .
It is understood that the technology of electrostatic powder spraying originated in the 1960s and was mainly applied to the coating of metal surfaces. It was not until the 1990s that it began to be applied to products on non-metallic surfaces. At present, furniture products from Japan, South Korea and other countries are more commonly used in this material.
PP material
No toxic, low cost
PP material (polypropylene) is a new material used in place of PVC. Unlike PVC, which produces harmful substances, PP materials do not contain toxic or hazardous substances such as formaldehyde, preservatives, pentachlorophenol, arsenic, heavy metal lead, mercury, cadmium, and chromium. At the booth of Shantou Donghe New Materials, the reporter saw that the “new environmental protection PP nano decorative fabric†jointly developed by the company and the Chinese Academy of Sciences has obtained the series of “interior decoration materials†and REACH tests, which are in line with furniture safety and hygiene. Environmental protection and other requirements.
In addition, PP materials are also resistant to scratches, abrasion, pollution, easy to clean, color, moisture and moisture. Its appearance can be close to natural materials and create realistic textures. As an alternative to PVC, PP materials can be applied not only to panel furniture veneers, wardrobe cabinet veneers, but also to paint-free doors, wood floors, wallpapers, decorative panels, household appliances, speakers, cabinets, gift boxes, handicrafts, etc. . According to the relevant person in charge of Donghe New Materials, in domestic and foreign markets, PP materials are widely used in homes, hospitals, schools, office buildings, factories, public places, supermarkets, businesses, sports venues and other places.
The reason why PP materials are used less in China is mainly because the materials are difficult to bond with other substances, so their application in more fields is limited. However, Rudong and the patented PP material products are coated with a polypropylene surface-modified primer with a thickness of only 0.01-0.02 mm on the surface of the polypropylene material to enhance the adhesion of the polypropylene material through such special The surface treatment allows the surface of the polypropylene material to be printed using ordinary inks, and the bonding effect is good.
