Menene aikin methyl cellulose ether a bushe foda turmi?
A: Methyl hydroxyethyl cellulose ether (MHEC) da methyl hydroxypropyl cellulose ether (HPMC) ana kiransa tare da methyl cellulose ether.
A fagen busasshen turmi foda, methyl cellulose ether muhimmin abu ne da aka gyara don busassun turmi irin su plastering turmi, plastering gypsum, tile m, putty, matakin kai, fesa turmi, fuskar bangon waya m da caulking abu.A daban-daban busassun turmi foda, methyl cellulose ether yafi taka rawar da ruwa rike da thickening.
Menene tsarin samar da ether cellulose?
Amsa: Da fari dai, ana murƙushe albarkatun cellulose, sa'an nan kuma an yi alkalized kuma a juye a ƙarƙashin aikin soda na caustic.Ƙara olefin oxide (kamar ethylene oxide ko propylene oxide) da methyl chloride don etherification.A ƙarshe, ana gudanar da wanke ruwa da tsarkakewa don samun farin foda.Wannan foda, musamman maganinta na ruwa, yana da kaddarorin jiki masu ban sha'awa.Eter cellulose da ake amfani da shi a cikin masana'antar gine-gine shine methyl hydroxyethyl cellulose ether ko methyl hydroxypropyl cellulose (wanda aka rage a matsayin MHEC ko MHPC, ko kuma mafi sauƙaƙan suna MC).Wannan samfurin yana taka muhimmiyar rawa a fagen busasshen turmi foda.muhimmiyar rawa.
