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 decoration For many people who are preparing for renovation, since home improvement pollution is so serious, how can we prevent it?
Eyes and nose and identification of environmentally friendly wood to identify home decoration wooden building materials furniture is the first to pass the nose this pass, take a piece of wood, in the side slot site smell (if the furniture on the furniture surface and inside the door smell), if more pungent, It shows that the emission of formaldehyde is relatively high and is absolutely not optional.
It is not enough to pass the smell, but further differentiation depends on the vision.
Method one: Look at the certification of any timber. If you claim environmental protection, you must have a ten-ring certification mark for the green building materials of the State Environmental Protection Administration. Wooden furniture requires certification from the China Quality Certification Center (CQC).
Method two: To see the report floor and furniture requires the merchant to provide a test report of an authority at or 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 amount of formaldehyde released from graded 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 paint on the green paint market is dazzling, people can not start. Here are five steps to teach you to choose environmentally friendly and healthy paint.
Step one: Look at the labels on the outer packagings of the paint. The identification should include the product name, implementation standard number, place of production, model, 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 to lift the paint bucket, shake it, if there is a crackling sound, indicating that the paint packaging is insufficient, less than two, the viscosity is too low, the formal manufacturers are real materials, Akira almost can not hear To the sound.
Step 4: Buy the least number of dealers to consult the painter's number of brushing passes and brushing area, the calculation of the amount and cost per square meter of material, not to be deceived by the price of each group (barrel).
Step 5: Buy professional products with good quality and strong support are often more professional, provide technical guidance and after-sales service according to different plates.
Environmental certification knows that 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.
