HEMC LH 6000

I-EipponCell® HEMC LH 6000 i-hydroxyethyl methyl cellulose yi-ether engeyiyo ionic cellulose eyenziwe ngenkqubo yekhemikhali ebandakanya umqhaphu, umthi we-alkalized, i-ethylene oxide, kunye ne-methyl chloride ether.Okwangoku, inkqubo yokuvelisa i-HEMC ingahlelwa kwiindlela ezimbini eziphambili: indlela yesigaba solwelo kunye nendlela yesigaba segesi.Kwindlela yesigaba solwelo, izixhobo ezisetyenzisiweyo zineemfuno ezisezantsi zoxinzelelo lwangaphakathi, nto leyo eyenza ukuba kungabi yingozi kangako.I-cellulose ifakwe kwi-lye, ekhokelela ekudumbeni ngokupheleleyo kunye ne-alkalization.Ukudumba kwe-osmotic yolwelo kuluncedo kwiselulosi, okukhokelela kwiimveliso ze-HEMC ezineqondo elifanayo lokutshintsha kunye ne-viscosity.Ngaphezu koko, indlela yesigaba solwelo ivumela ukutshintshwa kwemveliso ngokulula.Nangona kunjalo, umthamo wemveliso wereactor ulinganiselwe (ngokuqhelekileyo ngaphantsi kwe-15m3), nto leyo eyenza kube yimfuneko ukwandisa inani lereactors ukwenzela imveliso ephezulu.Ukongeza, inkqubo yokusabela ifuna isixa esikhulu se-solvent ye-organic njenge-carrier, ekhokelela kwixesha elide lokuphendula (ngokuqhelekileyo lidlula iiyure ze-10), ukunyuka kwe-solvent distillation recovery, kunye neendleko eziphezulu zexesha.Ngakolunye uhlangothi, indlela ye-gas-phase ibandakanya izixhobo ezidibeneyo kwaye inika isivuno esiphezulu sebhetshi enye.Ukusabela kwenzeka kwi-autoclave ethe tye, kunye nexesha elifutshane lokuphendula (ngokuqhelekileyo iiyure ezingama-5-8) xa kuthelekiswa nendlela yesigaba solwelo.Le ndlela ayifuni inkqubo yokubuyisela i-solvent enzima.Emva kokuba impendulo igqityiwe, i-methyl chloride engaphezulu kunye nemveliso ye-dimethyl ether iphinda isetyenziswe kwaye isetyenziswe kwakhona ngokwahlukileyo ngenkqubo yokubuyisela.Indlela yesigaba segesi ineendleko eziphantsi zabasebenzi kunye nokuncipha koxinzelelo lwabasebenzi, okukhokelela kwiindleko eziphantsi zokuvelisa xa kuthelekiswa nendlela yesigaba solwelo.Nangona kunjalo, indlela yesigaba segesi idinga utyalo-mali olubalulekileyo kwizixhobo kunye nolawulo oluzenzekelayo, olukhokelela kumxholo ophezulu wobugcisa kunye neendleko ezinxulumene nazo. Indawo yokuthenga iCas HEMC LH 6000
