I-HEMC LH 6000

I-EipponCell® HEMC LH 6000 hydroxyethyl methyl cellulose iyi-ether engeyona ionic cellulose eyenziwe ngenqubo yamakhemikhali ehlanganisa ukotini, ukhuni lwe-alkalized, i-ethylene oxide, ne-methyl chloride ether.Njengamanje, inqubo yokukhiqiza ye-HEMC ingahlukaniswa ngezindlela ezimbili eziyinhloko: indlela yesigaba se-liquid kanye nendlela yesigaba segesi.Endleleni yesigaba se-liquid, okokusebenza okusetshenzisiwe kunezidingo eziphansi zengcindezi yangaphakathi, okwenza kungabi yingozi kangako.I-cellulose ifakwe ku-lye, okuholela ekuvuvukeni okugcwele kanye ne-alkalization.Ukuvuvukala kwe-osmotic koketshezi kuzuzisa i-cellulose, okuholela emikhiqizweni ye-HEMC enezinga elilinganayo lokushintshwa kanye ne-viscosity.Ngaphezu kwalokho, indlela yesigaba se-liquid ivumela ukushintshwa kwemikhiqizo ehlukahlukene.Kodwa-ke, amandla okukhiqiza we-reactor anomkhawulo (imvamisa engaphansi kuka-15m3), okwenza kube nesidingo sokwandisa isibalo sama-reactor ukuze kukhiqizwe okuphezulu.Ukwengeza, inqubo yokusabela idinga inani elikhulu le-solvent ephilayo njengesithwali, okuholela ezikhathini zokusabela ezinde (ngokuvamile ezidlula amahora angu-10), ukukhuphuka kokutholakala kwe-solvent distillation, kanye nezindleko zesikhathi esiphezulu.Ngakolunye uhlangothi, indlela yesigaba segesi ihlanganisa imishini ehlangene futhi inikeza isivuno esiphezulu seqoqo elilodwa.Ukusabela kwenzeka ku-autoclave evundlile, enesikhathi esifushane sokuphendula (imvamisa amahora angama-5-8) uma kuqhathaniswa nendlela yesigaba soketshezi.Le ndlela ayidingi uhlelo oluyinkimbinkimbi lokubuyisela i-solvent.Ngemva kokuqedwa kokusabela, i-methyl chloride eyeqile kanye ne-by-product dimethyl ether zigaywa kabusha futhi ziphinde zisetshenziswe ngokuhlukile ngohlelo lokutakula.Indlela yesigaba segesi inezindleko eziphansi zokusebenza kanye nokuncipha kwamandla okusebenza, okuholela ezindlekweni zokukhiqiza eziphansi uma kuqhathaniswa nendlela yesigaba soketshezi.Kodwa-ke, indlela yesigaba segesi idinga ukutshalwa kwezimali okukhulu kwemishini nokulawula okuzenzakalelayo, okuholela kokuqukethwe okuphezulu kwezobuchwepheshe kanye nezindleko ezihambisanayo. Ungathenga kuphi i-Cas HEMC LH 6000
