甲醛防护剂的制备及防护性能研究

Preparation and protective performance of formaldehyde inhibitor

甲醛(HCHO)是一种常见的室内空气污染物,其毒性较高,对人体产生极大危害,目前使用的治理方法分为臭氧氧化法、吸附法、光催化氧化法和金属氧化物法。拟利用吸附法和金属氧化法的方式,通过化学反应或催化作用净化甲醛气体,对甲醛气体的防护材料进行制备工艺研究及防护性能评价,找出最佳的制备工艺及防护材料。

Formaldehyde,which has a fatal effect on people＇s health,is the main pollutant in indoor air.The strategies contain oxidation by ozone,chemical or physical absorption,oxidation by metal oxide and ultraviolet.By using the method of adsorption and metal oxidation,the formaldehyde gas is purified by chemical reaction or catalytic action.The preparation process and protection performance of the protective material for formaldehyde gas are evaluated,and the best preparation technology and protective material are found.
