In the modern decoration, a large number of composite sheets, adhesives and paints are used, which are the main sources of pollution of formaldehyde, benzene, ammonia, TVOC, toluene, xylene and other toxic gases. Because the biggest source of toxic gas is the adhesive, most of the building materials have adhesive components. For example, urea formaldehyde resins based on formaldehyde are used as binders in various particleboards, medium density fiberboards, and plywoods on the market. The harm of these poisonous gases is very great. Every year, more than 100,000 people die from home decoration pollution.

Green building materials to build green home improvement
For many people who are preparing to decorate, since the pollution of home furnishings is so serious, how can we prevent it?
Eyes and nose and identify environmental protection wood
Identification of furniture, wooden building materials, furniture, whether it is environmental protection, the first thing is to pass the nose, take a piece of wood, smell in the edge of the groove (if the furniture smells on the furniture surface and the door inside), if more pungent, that the amount of formaldehyde release comparison High is absolutely not optional.
It is not enough to pass the smell, but further differentiation depends on the vision.
Method One: See Certification
Any wood, if declared environmental protection must have the National Environmental Protection Administration's green building materials ten ring certification mark. Wooden furniture requires certification from the China Quality Certification Center (CQC).
Method Two: Look at the report
Floors and furniture need merchants to provide inspection reports of authorities above the provincial level. It is worth noting that the inspection report must be issued by the quality inspection department of the place of sale. In addition, furniture must provide product specifications, which were only recently mandated.
Method 3: Look at the level
The amount of formaldehyde released from wood is a certain standard. At present, the national standard for wood used indoors is E1, which means that 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 wood is the most environmentally friendly on the market, but the price is also more expensive. The price of blockboard (sandwich panel) is above 140 yuan/m2; the price of decorative panel is also above 100 yuan/m2; and the floor is above 200 yuan/m2.
The specific identification method uses blockboard (sandwich board) as an example. The sides of the plates produced by regular manufacturers are clearly printed with specifications, grades, exemptions, and formaldehyde release levels.
Five-step smart selection of environmentally friendly paint
There is a dazzling array of paint on the market and it is impossible to start with. Here are five steps to teach you to choose environmentally friendly and healthy paint.
Step one: Look at the labeling of the paint overpack
These logos should include the product name, implementation standard number, place of production, model number, specifications, and instructions for use. If it is a well-known brand, it is generally accompanied by a national exemption certificate, a famous brand certificate and a well-known Chinese trademark mark.
Step two: see if it meets the standard GB18581-2001
Wood lacquer must meet GB18581-2001 "indoor decoration materials, solvent-based wood coatings in hazardous substances limit." At the time of purchase, the seller may be required to provide a qualified environmental protection test report issued by a qualified unit.
Step 3: Buy the heaviest package
Lift the paint bucket and shake it. If there is a crackling sound, it means that the paint packaging is not enough. There are two short weights, and the viscosity is too low. The regular factory is really real and can hardly hear the sound.
Step 4: Buy the least amount of consumption
Ask the seller about the number of painting passes and area of ​​the paint, the amount of calculation and the cost of materials per square meter, not to be deceived by the unit price of each group (barrel).
Step 5: Buy Professional Supporting
Good quality products are often more professional, providing technical guidance and after-sales service according to different plates.
Environmental certification knows good plastic
The amount of adhesive used in home decoration is large, but selection is not the best source of pollution. Good glue will have environmental labeling product certification. The fake and inferior adhesives are also distinguished. The main features are: colloidal turbidity, delamination after storage for a long time, and smell of redness when the container is opened.
