Renovation of the demons and angels
Decoration which is not environmental protection, unhealthy indoor environment and polluted decoration could do harm to people's health. And in recent years, such as formaldehyde, formaldehyde of leukemia in each big news media, the newspaper reported, has aroused extensive attention of people from all walks of life. So formaldehyde is so terrible, why decoration can not do without it? It is necessary for us to understand.
Extensive use of formaldehyde
Formaldehyde is is the backbone of the downstream products of methanol which has a wide range of USES, simple production process, raw material supply sufficient mass chemical products. World output is 25 million tons, 30% methanol is used for production of formaldehyde. But formaldehyde is a kind of low concentration aqueous solution, from the economic point of view, it is not convenient to transport over long distances, so usually set up near the main consumer market, import and export trade and rarely. Formaldehyde can be directly used for disinfection, sterilization, preservatives, is mainly used for organic synthesis, synthetic materials, coating, rubber, pesticide and other industries. Its derivatives have mainly paraformaldehyde, polyformaldehyde, phenolic resin, urea formaldehyde resin, amino resin, lotto and polyol, etc. Meanwhile, the development of man-made board industry has been a great demand for formaldehyde.
Formaldehyde has a very wide range of USES, such as synthetic resin, surface active agent, plastic, rubber, leather, paper, dyes, pharmaceuticals, pesticides, photographic film, explosives, building materials and disinfection and fumigation and antisepsis were used in the process of formaldehyde. We can say that formaldehyde is a generalist in chemical industry.
Why decoration can't leave the formaldehyde glue
Formaldehyde is a kind of good fixative, it has many advantages:
Contract the organization, less damage, preserve natural substances.
Fixed uniform, strong penetrating power.
Hardening can make the organization, to increase tissue elasticity, which is beneficial to slice.
Can save the fat and lipid.
The cost is low.
Formaldehyde is the main reason for the anti-corrosion properties of sterilization which is a organism itself on the protein of amino can react with formaldehyde. Formaldehyde polycondensation reflect, stable performance of glue.
The fact that need to be clarified:
Nowadays, consumers are almost talk aldehyde, almost think the taste of the furniture such as wooden door is formaldehyde, actually otherwise, now used in decorating a process of chemical products is various, not only formaldehyde.
Harmful Gas list:
The first: radon
Radon is a radioactive inert gases which is a colorless, odorless, and exists in the cement, sand, natural marble.
Hazard: indoor radon pollution pollutants after smoking, lung cancer causes the second.
The second: formaldehyde
A strong smell of formaldehyde. Mainly comes from man-made plank, by using the adhesive formaldehyde.
Hazard: after inhaling formaldehyde, there will be a chronic poisoning or severe respiratory disease.
Benzene is a colorless liquid, with special aromatic smell.
Harm: long-term inhalation benzene can cause aplastic anemia.
Mainly comes from concrete antifreeze. Ammonia is easily soluble in water, eyes, throat and upper respiratory tract is fast, strong excitant.
Hazard: long time exposure to low concentration of ammonia, easy cause sore throats, hoarseness, pulmonary edema.
Formaldehyde can also generate other harmless aldehyde, so can directly use harmless alternative formaldehyde aldehyde. Such as phenol, urine aldehyde, and so on. Like a lot of good door companies have to switch to harmless aldehyde material.
Removal of formaldehyde
Generally formaldehyde exceeds bid in almost all the new decoration house, formaldehyde volatilization time for 3 to 15 years.
1. the ventilation method. Outdoor formaldehyde content is zero. No matter how high indoor formaldehyde content, ventilation can be instantly put it down.
2. activated carbon adsorption method. Activated carbon is internationally recognized as drugs, activated carbon masks, gas masks are using activated carbon. Use of the physical functions of activated carbon deodorant without any chemical additives.
3. plants in addition to taste. According to the different function of the room, area, the size of the choice to put the plant. In general, about 10 square meters room, 1.5 meters tall put two POTS of plants is more appropriate.
4. the chemical method, through chemical reaction to achieve the effect of removing. Spray drugs such as governance is easy to cause the secondary pollution, and may damage the furniture. And spray to the volatilization of formaldehyde have no effect.
