甲醛是一种具有强烈刺激性气味的无色液体,密度为0.815,沸点-21℃,可与水或醇任意混合,35％～40％的甲醛水溶液称为福尔马林。通常在甲醛水溶液中加8％的甲醇防止聚合,由于还原作用和蛋白质的氨基酸结合,使蛋白质变性凝固,所以作生物标本的防腐剂或消毒剂。笔者在制种实践中,摸索出直接蒸发甲醛水溶液消毒空气的方法,其过程是:按每m~3用甲醛17ml,加入17ml 水,用200W 加热器加热。消毒时接种箱、室要封闭,蒸发后切断电源,过30分钟即可接
Formaldehyde is a colorless, intensely irritating odorless liquid with a density of 0.815 and a boiling point of -21 ° C. It is optionally mixed with water or alcohol. Formaldehyde is a 35% -40% formaldehyde solution. Usually 8% methanol in aqueous formaldehyde solution to prevent polymerization, due to the reduction and protein amino acid binding, the protein denaturing coagulation, so as a biological specimen preservatives or disinfectants. In seed production practice, the author explored a method of directly evaporating formaldehyde aqueous solution disinfection air, the process is: according to each m ~ 3 formaldehyde 17ml, add 17ml water, heated with a 200W heater. Disinfection vaccination box, room to be closed, cut off the power after evaporation, can be accessed over 30 minutes
