How to control the environmental performance of home
People pay more attention to healthy life. The more "home improvement environmental protection" is mentioned. Usually, we pay more attention to wall paints and plates, but in fact home decoration is a complicated process. Even the unimpressive styrofoam and interface agents are closely related to environmental protection. Ask the relevant experts to explain in detail the key points related to environmental protection in home improvement. Only by controlling them can the environmental performance of the entire home space be guaranteed. Wall engineering Interface agent and putty Wall projects include pulling, wall mounting, batch scraping and other projects. In general, even these small processes and materials, most of them are also closely linked with environmental protection. Wall covering means adding cement-based slurry on the original cement base to increase adhesion and make the wall rougher before the kitchen and bathroom walls are tiled. In general, cement mortar itself does not produce harmful substances. “Wall wall sealing means that before the interior wall putty screed treatment, on the rougher base, brushing the glue to increase the adhesion of the solidified substrate makes the surface of the base layer solid, which can increase the cement mortar adhesion to the grassroots. It is also commonly understood to brush the interface agent onto the wall." In a certain range, the wall and the top surface can be leveled using a putty to smooth the uneven wall and the top surface. But the role of putty is not only to level the wall but also to improve the smoothness of the wall. According to reports, the general interface agent and putty need to be doped with a certain amount of glue in order to effectively adhere to the wall, but the glue usually contains formaldehyde, benzene and other harmful substances. The really good environmental protection putty is a mixture of pure ecological raw materials and inorganic additives. It does not contain harmful substances such as benzene series and formaldehyde. Therefore, the key factor in determining whether the interface agent and the putty are environmentally friendly is the composition of the glue. Ground Engineering Waterproof coating The bathroom and kitchen waterproofing project is a ground coating project that prevents the owner from leaking downstairs when using water in life, and does not cause leakage, water seepage, etc. to neighbors downstairs. According to experts, waterproof coatings used in previous years were mostly felts, asphalts, polyurethanes and other materials containing toxic and hazardous substances. In recent years, the home improvement industry has basically used a waterproof coating whose main component is a one-component cement-based acrylate. Although within the scope of national regulations, these coatings also contain a small amount of harmful substances such as formaldehyde and TVOC. At present, waterproof coatings made of two-component acrylic acid or ethylene propylene diene, their harmful substances such as formaldehyde and TVOC have tended to be zero. Experts said that according to the different classification of the waterproof coating, the limits of its harmful substances are also different. The building material industry standard JC/T 1066 “Restriction Standards for Waterproof Coatings of Harmful Substances†applies to volatile organic compounds (VOC), benzene, toluene and ethylbenzene in building waterproof coatings. Xylene sum, free formaldehyde, heavy metals, phenol, hydrazine, naphthalene and other limited quantities. When consumers choose, they can pay more attention to the composition of the waterproof coating and try to choose the water-based material. Floor adhesive and tile adhesive For non-locking floors, floor adhesives are required for installation and fixing; some floors that are floor-heated cannot be nailed and are not convenient to use suspension-type paving methods, and are generally fixed by using floor glue. In addition, some gaps between the floor and the floor also need to be filled with glue. "Otherwise, dust and sand will enter the bottom of the floor through the gap. When people step on it, they will 'smoke'." Since it involves plastic, it will not only need to consider its construction performance, that is, the bonding ability is good, but also have to consider whether it is environmentally friendly. . A good film should be waterproof and moisture-proof, which can prevent the floor moisture moisture from attacking the floor and effectively avoid the risk of floor deformation due to moisture exposure. Tile adhesives, that is, tile adhesives, consist of inorganic bonding materials, fine aggregate fillers and synthetic resins, flexible reinforced polymer and special additives. It is an item used for pasting tiles and can be used as a substitute for cement mortar, which is the tile adhesive used in the thin paste method. On the one hand, it needs to have a strong bonding force to ensure the durability of the tile on the wall. On the other hand, due to the glue involved, experts call for consumers to pay attention to their environmental performance. Painting works Latex paint and wallpaper glue The paint project is mainly a wall and top finish project, that is, painting or pasting wallpaper on the leveling wall and the top surface with latex paint (known as paints). The materials involved are mainly latex paint and wallpaper glue. For latex paint, everyone pays more attention. The limit detection of harmful substances in latex paint includes a number of contents: volatile organic compounds (VOC), the sum of benzene, toluene, ethylbenzene, free formaldehyde and heavy metals. VOC is a general term for various volatile organic compounds. Some of them are carcinogens or suspected carcinogens recognized by the World Health Organization. They can stimulate the eyes and respiratory tract and cause skin allergies. Free formaldehyde is also a major contaminant in the indoor environment. Long-term exposure can cause people to feel uncomfortable, headaches, dizziness, nausea and even nasal cancer. Heavy metals also have serious damage to human bodies. Most of the products currently on the market are in line with national standards, but because latex paints need to be used in large areas at home, consumers still have to choose regular manufacturers to produce products that meet the national standards by the national authoritative testing organizations. If you paste wallpapers, one of the environmental aspects that owners often overlook easily is wallpaper glue. The limited amount of harmful substances in wallpaper glue is free formaldehyde, benzene series, chlorinated hydrocarbons, formaldehyde, total volatile organics, etc., and it needs to comply with GB18583-2008 "Restrictions on harmful substances in interior decoration materials stickers" and HJ/T220 "environment Marking product technical requirements - adhesive" requirements. Wood works Plates, accessories and painted wood works mainly include door and window foundation finding projects and on-site wooden works. The term “door and window foundation search party†refers to the correction project done by the construction personnel using materials such as blockboard when the door and window openings of the original civil works are not up to the required squareness requirements and dimensional requirements for the installation of finished door and window covers. The woodworking project refers to the process that some owners need to make wooden items and wooden furniture on site during the renovation. Plate Plates are generally divided into plywood and wood-based panels. The plywood consists of veneer (plywood), blockboard (large core board) and multi-layer plate, which are made of molded wood; and the plywood is divided into density plate, particle board and straw plate, which are crushed with related raw materials. After molding plate. Manufacturers use these glues without exception. Whether the plate is environmentally friendly or not, the key is glue. In order to increase the bonding strength, unscrupulous manufacturers will use a large amount of low-cost glue, which will result in uncontrollable release of free formaldehyde in the sheet, resulting in excessive formaldehyde. The extensive use of plates in decoration will inevitably cause woodwork to make heavy use of glue during the splicing process. If these glues contain too much formaldehyde, they can also cause pollution. Therefore, the best choice for consumers to decorate or choose a formal home improvement company, so that you can basically guarantee that the sheet and glue meet environmental requirements. Green sheets must smell free from the irritating smell of formaldehyde, and the key is to require manufacturers and distributors to provide certificates that pass environmental certification. Accessories In the woodworking materials, white latex, putty (wooden putty), and furniture paint are indispensable. The putty is mainly used for the filling of metal surfaces and the filling of wooden furniture and uneven surfaces of wood. Huang Hao said that most of these materials achieve adhesion through morphological changes from liquid to solid state, and generally involve the problems of formaldehyde and benzene. In bonding wood, it is necessary to ensure that the adhesive is environmentally friendly. "If you can purchase materials yourself, you can control the environmental performance of the materials from the source." paint After finishing the woodwork, it is usually painted. Consumers need more attention. General paints will promote the elimination of hazardous materials such as benzene, toluene, and formaldehyde, but in fact, there is a need to pay attention to the content of free TDI. TDI is the abbreviation of toluene diisocyanate. This material is mainly used in the manufacture of curing agents for polyurethane materials. After a high concentration of free TDI is inhaled into the respiratory tract by humans, lighter ones can cause symptoms such as coughing chest tightness, shortness of breath and asthma, and in severe cases can cause pulmonary edema and coma and even death. Long-term exposure to TDI may cause cancer. However, Bai Yongzhi introduced that although TDI is very toxic, the TDI content in paints is very low, and its volatilization is also a matter of construction within a short period of time. It is not as harmful as toluene, xylene and other volatile substances in paint solvents during construction. Big. He suggested that after the renovation of the new home do not immediately stay, every day window ventilation, if the conditions allow new homes vacant as long as possible, before moving into a new home, it is best to find a qualified national professional indoor air testing agency to detect indoor air, Qualified before moving into a new home. >>> Links: 27 Laws for Environmental Home Improvement Factory products Cabinets and furniture As far as the current home improvement process is concerned, many decoration companies can provide corresponding finished furniture such as whole cabinets and furniture. These are also important aspects of environmental home improvement. In addition to the environmental protection of finished furniture, the most important issue is the environmental protection of the plastic used. According to reports, the current use of urea-formaldehyde resin in the furniture sheet market is generally guaranteed by the addition of formaldehyde, which will lead to excessive formaldehyde. And even the fixed glue of the door-sleeve--whether the styrofoam is environmentally friendly or not, is related to the environmental performance of the entire space. Consumers need to pay attention to their environmental performance, in addition to focusing on their bonding strength. Expert advice Check test report Since many consumers choose not brand home improvement companies, many products are provided by home improvement companies. To ensure environmental protection, consumers can do the following: 1. Control the source of goods. If you can purchase it yourself, then you can purchase environmental products by yourself and check the environmental protection test report. 2. If the home improvement company purchases products, it is necessary to ask whether it is environmentally friendly before purchasing, and it is required to provide environmental protection inspection reports of authoritative departments; 3. When you use it, you can open it up to see if it is a smoked nose and simply judge whether it is environmentally friendly.
