Xinchuangyuan Wood helps you to buy green home building materials

Plate: E-level certification is a standard safety hazard: the main health problem that may exist in the plate is also the problem of excessive formaldehyde emission. See certification: Formaldehyde emission E0, E1 grade refers to the formaldehyde emission standard prescribed by the state, E0 grade products can be directly used indoors, E1 grade products must be finished finish treatment can be used indoors. Plates that are not marked E0, E1 are absolutely not used indoors. Veneer and blockboard can be divided into three grades according to their appearance and quality, such as superior products, enamel products and qualified products. According to the feeling: the width of the core strip of the large core board should be greater than 2.5 times of the thickness, the two end joints of the adjacent two rows of core strips should be larger than 50mm, the length of the core strip should be greater than 100mm, the gap of the side of the core strip should be less than 2mm, and the gap of the end face is smaller than 4mm. The most straightforward way to test the glue strength of a plywood is to use a sharp flat blade to warp along the glue layer. If the glue layer is broken and the wood is not damaged, the glue strength is poor. The natural warpage of the entire panel of the veneer should be as small as possible. Look at the brand: in the plate industry source Senyuan brand won the consumer affirmation. Consumers can go to the store to buy products, and the quality of the products is more secure.

Wood furniture: CQC certification must have safety hazards: unqualified wooden furniture, there may be cases of formaldehyde and benzene exceeding the standard. Excessive benzene can cause symptoms of central nervous system poisoning such as blurred vision, dizziness, and nausea. Look at the certification: When buying wooden furniture, we must look at CQC furniture product certification of China Quality Certification Center. It is a certification according to national mandatory standards. In addition, it depends on whether the business can provide inspection reports of authoritative institutions at or above the provincial level. In addition, the furniture must provide a product specification, which was recently mandated. By feeling: Before buying furniture, you should first ask the time the furniture is placed in the mall, then smell it on the surface of the furniture to see if there is a pungent smell. If you buy furniture such as cabinets, you should also open the door to smell the smell inside. If the furniture is left for a while, the pungent smell is still coming, no need to say, this must be unsafe furniture. Many consumers often neglect the craft quality of hinges, springs and other accessories, which must also be seen. The solidity of small accessories is directly related to the service life of furniture. Look at the brand: Yuansenyuan, Jimei, Qumei, Federation, Guangming, Fuzhidao, Star Dream, Hunter, Lixing, etc. are relatively recognized furniture integrity brands

All kinds of fascinating eyes, whether consulting ceramic tiles, flooring, plates or furniture, merchants will issue many test reports and various certifications, such as national environmental protection signs, green building materials product certificates, national standard product marks, "10 ring" certification, SGS Certification, national compulsory product certification, exemption marks, and engineering bids, etc., are dazzling, and businesses will also tell you some "small tips" for selecting safe building materials. It sounds reasonable and it looks good, but how to choose it, I still have no bottom, or listen to the opinions of experts.

Tiles: To choose the safety hazard of Class A radiation level : the damage of ceramic tiles mainly comes from radionuclides. The content of radionuclides in unqualified ceramic tiles often exceeds the standard. Living in such an environment for a long time is very harmful to health. Large, especially radioactive nuclides contained in ceramic products, long-term radiation to the human body will increase the risk of lung cancer. Look at the certification: tile products will do radioactive level testing, divided into three categories A, B, C, Class A is the best, the radioactive level is the lowest, this tile packaging will be marked: "Radioactivity level: A". Tiles can be divided into polished tiles and glazed tiles. Polished bricks are more harmful than glazed tiles because they contain more radionuclide components. Polished tiles must have national compulsory product certification (referred to as three C), while glazed tiles do not currently emphasize the need to do "three C" certification, other certifications such as environmental protection signs, quality system certification, national inspection-free signs are also important, to a certain extent It reflects the scale and strength of the production of ceramic tile enterprises. By feeling: take a sample brick to carefully observe all aspects of it, drop the ink on the back of the tile to see its diffusion speed to determine the water absorption rate, the water-absorbing tile is not good, easy to expand cracking, odor. In addition, the gloss and workmanship of the tiles are also an important criterion for selection. Look at the brand: Ceramic Industry Association announced the top ten brands of Chinese architectural ceramic products in 2005: Eagle, Dongpeng, Mona Lisa, Asia, Guanzhu, Diamond, Smick, Xinzhongyuan, Golden Rudder, Marco Polo. In addition, Nobel is also a good brand.

Wood floor: Ten-ring mark can not be lack of safety Hazard: Inferior wood floor may contain a higher concentration of formaldehyde, long-term living in an environment where formaldehyde concentration exceeds the standard, it will cause respiratory and blood system diseases. Look at the certification: national exemption certification, China environmental label (ie the ten ring mark) and ISO9000, ISO9001, ISO14000, ISO14001 and other system certification. Among them, the ten-ring mark can distinguish whether it is the standard of environmentally friendly flooring, and the mark has a strict scope of certification. By feeling: Take a piece of wood and smell it in the side slot. If it is pungent, the release of formaldehyde is relatively high. Take two pieces of wooden floor to make it together, and see if the uneven groove is tight. If the concave groove is not tightly engaged, the floor will be degummed after a period of use, and there will be gaps on the floor. After entering the water and dust, the floor will be deformed. Start the package. It is not advisable to choose a floor that is very dark or black, because the floor of this color may have poor wear resistance or poor surface definition. Look at the brand: 30 quality after-sales service selected by the China Timber Distribution Association Floor Committee double commitment solid wood flooring: living home floor, nature floor, Aibai floor, Fudeli floor, North American maple floor.
