1. I-Viscosity Control
High-viscosityi-hydroxypropyl methylcelluloseayikwazi ukukhiqiza i-cellulose ephezulu kakhulu kuphela ngokuyicofa bese ifaka i-nitrogen. Kodwa-ke, uma ithuluzi lokulinganisa i-oxygen lingafakwa kuketela, ukukhiqizwa kwe-viscosity kungalawulwa ngokuzenzakalelayo.
2. Ukusetshenziswa kwama-associative agents
Ngaphezu kwalokho, uma kucatshangelwa isivinini sokushintsha i-nitrogen, futhi ngesikhathi esifanayo, ukuqina komoya kwesistimu kuhle kakhulu, futhi kulula kakhulu ukukhiqiza imikhiqizo ephezulu ye-viscosity. Yebo izinga le-polymerization likakotini ocolisisiwe nalo libalulekile. Uma namanje kungasebenzi, kusetshenziswa indlela ye-hydrophobic association, futhi hlobo luni lwe-agent ehlangene olukhethiwe lunomthelela omkhulu ekusebenzeni komkhiqizo wokugcina.
3. Okuqukethwe kwe-Hydroxypropyl
I-oksijini esele kugedlela lokusabela ibangela ukuba i-cellulose yehle futhi isisindo samangqamuzana sinciphe, kodwa umoya-mpilo osele ulinganiselwe. Uma nje ama-molecule aphukile exhunywe kabusha, akunzima ukwenza i-viscosity ephezulu. Kodwa-ke, izinga lokugcwala kwamanzi nalo lihlobene eduze nokuqukethwe kwe-hydroxypropyl,Ezinye izimboni zifuna kuphela ukunciphisa izindleko nentengo, futhi azizimisele ukukhulisa okuqukethwe kwe-hydroxypropyl, ngakho ikhwalithi ayikwazi ukufinyelela izinga lemikhiqizo efanayo.
4. Ezinye izici
Izinga lokugcinwa kwamanzi lomkhiqizo linobudlelwane obuhle ne-hydroxypropyl, kodwa kuyo yonke inqubo yokusabela, liphinde linqume izinga lokugcinwa kwamanzi, umphumela we-alkalization, isilinganiso se-methyl chloride ne-propylene oxide, ukugxila kwe-alkali namanzi. Isilinganiso nekotini elicwengekile sinquma ukusebenza komkhiqizo.
