Molecular formula :
CAS :
nature : also known as the coagulating agent and agglutination agent. Sol and latex can condensed substances. Many types of applications is very broad. Such is the major electrolyte salts, which can ion and colloidal particles of opposite charge arising from the condensation. The latex industry can be divided into : (a) Strong coagulants, rapid coagulation, such as ammonium acetate and acetic acid in aqueous solution, the calcium nitrate alcohol (methanol or ethanol) solution; (2) reduce condensation agent, coagulation slower, for example, aqueous solution of sodium fluoride, and bentonite aluminum hydroxide colloid suspension of water; (3) Heat coagulants, under certain temperature can condensed latex material, application of zinc is more ammonia complexes [Zn (NH3) n] 2 +, from zinc oxide or zinc chloride and ammonia compounded in recent years, used various Hopewell % polymer such as polyethylene methyl ether, propylene glycol polyethylene oxide (molecular weight 500 to 850). In addition, water purification and the use of alum, aluminum sulfate tofu condensation of gypsum, and precipitation from the milk of Cool-acetate, are coagulants. As part of the soil by adding the hydrolysis of polyacrylonitrile, or sodium acetate hydroxylation of malic acid polymer, soil condensation can prevent were dispersed by the wind and water conservation role.
