Urea-formaldehyde resins under water, heat, light, the role of metal ions, slowly decomposing, continuous release of formaldehyde, ammonia. Urea-formaldehyde resin stability of different manufacturers and different production process, resulting in the release of formaldehyde different speeds. But what is certain is that no matter what the technology, the resin will have to release formaldehyde containing formaldehyde, as long as the sheet exists, formaldehyde will be a steady stream of "supply." However, this plate, but also has its benefits, and that is do not worry about it raw worms, even the eggs will be released formaldehyde to kill, this plate is made cabinets, saving money to buy camphor Chuzhou drug testing components, is not, and camphor properties close? Cheap aqueous coating binder 107,108 gum, component is a polyvinyl formal, this coating will release formaldehyde whitewash. There are similar phenolic resin glue, used for the production of Bakelite, the Department formed by the condensation of phenol and formaldehyde; Melamine Formaldehyde; both than the urea-formaldehyde resin "upscale" Some good some stability, but the price is too high, savvy Businessmen often do not use and release of formaldehyde is still inevitable trend. Cement antifreeze radon Radon is a natural hazard only natural radioactive noble gases Chuzhou drug testing produced by the decay of radium, it has no color, and no odor. Atoms of radon decay products in the air is called radon progeny, for metal particles. And radon daughters in air at room temperature to form radioactive aerosols and air pollution. Easy to be trapped respiratory system, and continue to accumulate in the local area induced lung cancer. Scientific research shows that radon radiation damage the human body accounts for more than 55% of human life in all suffered radiation damage, most of its incubation period induced lung cancer in more than 15 years, 1/5 of radon-related lung cancer patients in the world. So the CMA Chuzhou drug testing, radon is the second largest cause of human cancer, "killer", is in addition to lung cancer caused by smoking the second largest factor, World Health Organization makes it as one of the 19 kinds of carcinogenic substances Radon is a colorless, odorless, inert gas undetectable. Cement, bricks, sand, marble, tiles and other building materials are the main source of radon, geological fault zone at will have a lot of radon emanation. Radon and its daughters with the air into the body, or attached to the tracheal mucosa and lung surface, or dissolved in body fluids into the tissue to form in vivo radiation-induced lung cancer, leukemia and respiratory diseases. World Health Organization studies show that radon is second only to lung cancer caused by smoking the second largest carcinogens.
