Methylcellulose

Methyl cellulose, wanda aka rage a matsayin MC, kuma aka sani da cellulose methyl ether, shi ne nonionic cellulose ether. Yana da bayyanar fari, rawaya mai haske ko launin toka mai launin toka, granular ko fibrous, mai wari, maras amfani, mara guba da rashin haushi, hygroscopic.

Methylcellulose yana narkewa a cikin glacial acetic acid, amma ba zai iya narkewa a cikin kaushi na halitta kamar ethanol, ether, acetone, da chloroform. Methylcellulose yana da kaddarorin gel na thermal na musamman. Lokacin da aka narkar da shi a cikin ruwan zafi sama da 50 ° C, zai iya watse da sauri ya kumbura don samar da gel. Lokacin da ruwan zafi ya faɗi ƙasa da 50 ° C, zai narke cikin ruwa don samar da maganin ruwa. Maganin ruwa mai ruwa da siffofin gel zasu iya hulɗa da juna.

Shirye-shiryen na methyl cellulose yana amfani da cellulose na halitta irin su ɓangaren auduga da ƙwayar itace a matsayin kayan aiki, kuma ana amfani da su da alkali (irin su sodium hydroxide, da dai sauransu) don samun alkali cellulose, sa'an nan kuma a sanya shi ta hanyar ƙara methyl chloride. Reaction a wani zazzabi, bayan wanka, neutralization, dehydration, bushewa da sauran matakai, bisa ga samfurin tsarki da kuma fasaha abun ciki, methyl cellulose za a iya raba Pharmaceutical sa methyl cellulose, abinci sa methyl cellulose, general-manufa methyl cellulose da sauran kayayyakin. .

Methylcellulose yana jure wa acid da alkalis, mai, zafi, microorganisms da haske. Yana da kauri mai kyau, ƙirƙirar fim, riƙe ruwa, emulsifying, wetting, tarwatsawa, da kaddarorin mannewa.

Methylcellulose yana da nau'ikan aikace-aikace masu yawa na ƙasa, daga sutura, tawada, adhesives zuwa yadi, bugu da rini zuwa magani da sarrafa abinci. Yawancin masana'antu suna da buƙatun aikace-aikacen samfura kuma suna da faɗin sararin ci gaba. Bayan ci gaba na dogon lokaci, masana'antar methyl cellulose ta ƙasata ta samar da wani ma'auni, kuma kewayon samfurin yana ƙara zama cikakke, amma yana buƙatar zama cikakke ta fuskar ma'auni da ci gaba mai zurfi!
