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 from inexpensive metal detector urea-formaldehyde resin Chuzhou CMA certification, the paper, sawdust, wood shavings and other debris and even garbage scraps glued together Unqualified made of particleboard, MDF, Blockboard , fibreboard, laminated wood flooring and other wood-based panels (plywood). This low cost plastic Chuzhou metal detection mechanism, high adhesive strength, so 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. The radionuclide content in building materials shall comply with the relevant provisions of, or make indoor radiation dose rate increases, the indoor radon concentration. To try to use this property of materials. For real estate outside the building material to see whether after a radioactive test is a Class A (for interior decoration), Class B (available but there are certain radioactive, people do not often available in indoor public places), or C products ( only applies to the outdoor decoration) Chuzhou metal detector, and then determine its purpose. Building materials should be carried out at the factory radioactive test. In general, Jiangxi, Zhejiang, Anhui some local production of stone coal cinder brick or brick, which uranium, radium, thorium content is high, the use of special attention. Also pay attention to the choice of natural stone. Not all natural stone radionuclide concentrations are high and can not be used as building materials, natural stone, but some choose to pay attention. In general, magmatic rocks of acid intrusive rocks Chuzhou metal detector phone, such as granite, high radioactive content. Clastic sedimentary rocks of sedimentary rocks, such as shale, radioactive content is also higher than other stone. Granite and shale are not suitable for indoor use as building materials, especially suitable for use as bedroom interior decoration materials. Chuzhou metal detector company, CMA qualification (certified), Chuzhou, Chuzhou metal detection provided by the Green Ribbon Indoor Environmental Services Limited.
