Small molecules of formaldehyde, molecular formula HCHO, is a highly reactive organic, highly volatile at room temperature, at high concentration can evaporate into the air, has a strong irritating odor. Multi-made solution of formaldehyde 35% -40% concentration (commonly known as formalin) for saving cadavers, sterilization and production of wood, paper and other adhesives. Price low formaldehyde, urea can be made and inexpensive urea-formaldehyde resin, the paper, sawdust, wood shavings and other debris and even garbage scraps glued together Unqualified made of particleboard, MDF, block board, fiberboard, composite wood flooring and other wood-based panels (plywood). This glue low cost, high adhesive strength Tongcheng formaldehyde detection governance, it is widely used, it can be said more than 90 percent of the current market a variety of wood artificial board is made by this glue, so when you do not When indiscriminately use an ordinary plywood for raw materials, the introduction of the house put formaldehyde. Formaldehyde has a strong irritant, at lower concentrations, the human eye has a spicy sensation, tearing, redness and swelling. Higher concentrations, they will feel choked Tongcheng join formaldehyde detection governance, nausea and even difficulty breathing, choking. These "biochemical reaction" from the toxicity of formaldehyde. Formaldehyde is the smallest oxygenated organic compounds, has a high reactivity, can and with -OH (hydroxyl), - SH (thiol group), - NH2 (amino) groups in the molecule nucleophilic addition reaction Tongcheng addition to formaldehyde, Final formaldehyde as methylene (-CH2-) providers, two radicals react with the above groups, the free molecular chains are crosslinked by formaldehyde up, lose their physiological functions. This is like our hands, each hand on behalf of one of the above groups, like formaldehyde an original freedom handcuffs handcuffed hands (even handcuffed one), it makes our hands lost its freedom function. Within the body's cells, the enzyme system there are a lot of hydroxyl, mercapto, amino, will react immediately after exposure to formaldehyde, formaldehyde detection cytotoxic Tongcheng CMA qualification, protein denaturation (formaldehyde superior bactericidal capacity since this is the original reaction). From this "biochemical reaction" immediate results, that people feel unwell; in the long run, can not exclude potentially carcinogenic formaldehyde Tongcheng Tongcheng addition to formaldehyde formaldehyde detection governance _ _ Green Ribbon Green Ribbon indoor environment by Chuzhou Environmental Services Ltd. available.
