    Core tips: formaldehyde can be made into finishing agent, color fixing agent, softener and urea formaldehyde resin adhesive, mainly from synthetic fabrics such as artificial board, furniture, adhesives used in decoration and carpet These products can continuously decompose and release a large amount of formaldehyde The indoor concentration change is mainly related to the release amount and release rule of the pollution source, as well as the service life, indoor temperature, humidity and ventilation degree, among which the temperature and ventilation are the most important factors Formaldehyde can be absorbed through respiratory tract, and its aqueous solution "formalin Rd" Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: formaldehyde can be made into finishing agent, fixing agent, softener and urea formaldehyde resin adhesive, etc., mainly from man-made boards, furniture and decoration adhesives and carpets and other synthetic fabrics These products can continuously decompose and release a large amount of formaldehyde The indoor concentration change is mainly related to the release amount and release rule of the pollution source, as well as the service life, indoor temperature, humidity and ventilation degree, among which the temperature and ventilation are the most important factors Formaldehyde can be absorbed by respiratory tract, its aqueous solution "formalin" can be absorbed by the digestive tract, and long-term exposure to formaldehyde can cause chronic respiratory diseases, menstrual disorders, pregnancy syndrome, which cause neonatal physical deterioration, induce blood diseases in children, increase the incidence rate of children asthma, lead to lead poisoning in children, and greatly reduce the intelligence of children, and high formaldehyde concentration It is toxic to nervous system, immune system, liver, etc formaldehyde has teratogenic and carcinogenic effects People exposed to formaldehyde for a long time can cause cancer of nose, mouth, nasopharynx, throat, skin and digestive tract At ordinary times, it should be noted that if there is a wardrobe made of wood-based panels, try not to put underwear, pajamas and children's clothing in it before formaldehyde is removed The following methods can be adopted to remove formaldehyde: adsorption method: put honeycomb particle filler such as activated carbon in the room, fix pollutant molecules or atomic groups into the filler by physical adsorption, and replace the filler regularly to achieve the purpose of continuous treatment, which is suitable for low concentration pollution treatment This method is simple, convenient and cheap, but the effective area of treatment is small, the duration is short, the degree of treatment is limited, and the effect of gas pollutants is poor Negative oxygen ion method: the negative oxygen ion generating device is used to produce high concentration of negative oxygen ions, and the pollutants are treated by the charge and oxidation of negative oxygen ions, which is suitable for the treatment of low concentration pollution The price is relatively low, the operation is simple, the effect of bacterial treatment is obvious, the treatment intensity is not high, the treatment scope is limited, the negative oxygen ion is easy to be converted into ozone, causing secondary pollution Electromagnetic wave and ultrasonic method: use the treatment device to generate electromagnetic wave or ultrasonic with a certain frequency, so as to remove bacteria, dust and simple gas pollutants in the air, and use static electricity for adsorption Simple operation, good effect on bacteria and dust, long duration, but high price, no obvious effect on pollution gas treatment Chemical method: by fixing or spraying different chemical reagents on the surface of walls and building materials, and directly treating one or several pollutants by chemical reaction, it is applicable to the treatment of medium and low concentration pollution The price is relatively low It can be used for indoor air pollution and building materials and furniture pollution In short term, the effect is obvious, and the duration is relatively short The toxic side effects of individual treatment products are easy to cause secondary pollution Photocatalyst: at present, the most advanced photocatalyst in China is used to remove formaldehyde Its principle is to spray liquid products containing nano-sized titanium dioxide on the surface of indoor walls or furniture materials, and use titanium dioxide as catalyst to decompose nearby air into super oxide and hydroxyl group with strong oxidation under the condition of light, The oxidation of pollutants is to turn them into carbon dioxide and water The treatment of pollutants has a wide range of types, long duration, no secondary pollution, absolutely green It is a product certified by who It is not only long-lasting in efficacy, but also colorless and tasteless, will not damage your home, and will not cause secondary pollution Choose jingwanjia, free from worries, so that you have a green and healthy living space
