Khoom Description
Paraformaldehyde yog polymeric daim ntawv ntawm formaldehyde. Nws yog ib qho khoom. Nws yog qhov tsawg tshaj plaws polyoxymethylene, cov khoom polymerization ntawm formaldehyde nrog ib tug raug℃ntawm polymerization ntawm 8-100 units. Paraformaldehyde feem ntau muaj me ntsis tsw ntawm formaldehyde vim decomposition. Paraformaldehyde yog poly-acetal.
Daim ntawv thov
Paraformaldehyde yog siv los ua fumigant, tshuaj tua kab mob thiab hauv kev tsim cov khoom siv hluavtaws xws li melamine resin, phenol resin thiab polyacetal resin. Nws kuj yog siv rau hauv kab lis kev cai ntawm tes. Nws kuj yog ib qho fixative hauv electron microscopy. Nws kuj yog siv rau hauv kev npaj ntawm formalin fixatives rau cov ntaub so ntswg los yog hlwb. Txhawm rau siv cov tshuaj ua ib qho fixative, nws yuav tsum tau hloov mus rau monomer formaldehyde los ntawm cua sov li formaldehyde yog cov tshuaj nquag hauv kev kho..
