[ Chinese wardrobe net ] In the modern decoration, a large number of composite sheets, adhesives and paints are used. These are the main sources of pollution of formaldehyde, benzene, ammonia, TVOC, toluene and xylene. Because the biggest source of poison gas is the binder, and most building materials have adhesive components. For example, urea-formaldehyde resin with formaldehyde as the main component is used as a binder in various particleboards, medium-density fiberboards and plywood on the market. The dangers of these poisonous gases are very large, and more than 100,000 people die every year from home pollution.
Method 1: Look at the certification
Any wood material, if it claims to be environmentally friendly, must have the Green Building Materials ten-ring certification mark of the State Environmental Protection Administration. For wooden furniture, CQC furniture product certification from China Quality Certification Center is required.
Method 2: Look at the report
Floors and furniture require merchants to provide inspection reports from authorities above the provincial level. It is worth noting that the inspection report must be issued by the quality inspection department at the place of sale. In addition, the furniture must provide a product specification, which was recently mandated.
Method three: look at the level
There is a certain standard for the amount of formaldehyde released from wood. The current national standard for wood for indoor use is E1, that is, the formaldehyde emission is 0.5mg/I~1.5mg/I; and the E0 standard with formaldehyde emission less than 0.5mg/I is the European standard that will be adopted in China. This kind of wood is the most environmentally friendly on the market, but the price is also more expensive. The price of blockboard (sandwich board) is above 140 yuan / square meter; the price of decorative board is also above 100 yuan / square meter; and the floor is more than 200 yuan / square meter.
