Ungahlulela kanjani ikhwalithi ye-cellulose kusuka kumlotha we-hydroxypropyl methylcellulose ngemuva kokuvutha

Okokuqala, sidinga ukuqonda ukuthi yini umlotha:

01. Okuqukethwe komlotha kubizwa nangokuthi izinsalela ezivuthayo, ezingaqondwa kalula njengokungcola emkhiqizweni.Izokhiqizwa ngokwemvelo ngesikhathi sokukhiqiza.Ngemuva kokuthi umkhiqizo uphume ku-reactor ye-etherification, uzongena ethangini le-neutralization.Ethangini le-neutralization, inani le-pH lilungiswa kuqala ukuze lingathathi hlangothi, bese kunezelwa amanzi ashisayo ukuze kugezwe.Amanzi ashisayo engeziwe , Ukugeza, izikhathi eziningi zokugeza, ukwehla komlotha, futhi okuphambene nalokho.

02. Ubukhulu bomlotha bubuye bubonakale ekuhlanzekeni kwe-cellulose, ukuphakama kokuhlanzeka, umlotha omncane ngemva kokushisa!

Okulandelayo, ake sihlaziye ulwazi esiluthola ngenqubo yokushiswa kwe-hydroxypropyl methylcellulose.

Okokuqala: Ukuncipha komlotha, ikhwalithi ephezulu

Izinqumo zenani lensalela yomlotha:

(1) Ikhwalithi yempahla eluhlaza ye-cellulose (ukotini ocolisisiwe): Ngokuvamile, ikhwalithi engcono kakotini ocolisisiwe, lapho i-cellulose ikhiqizwa ibe mhlophe, kuba ngcono umlotha nokugcinwa kwamanzi.

(2) Inani lezikhathi zokugeza: kuzoba nothuli nokungcola ezintweni ezingavuthiwe, izikhathi eziningi zokugeza, kuncane umlotha womkhiqizo oqediwe ngemuva kokushiswa.

(3) Ukwengeza izinto ezincane emkhiqizweni ophelile kuzoholela emlotheni omningi ngemva kokushiswa

(4) Ukwehluleka ukusabela kahle phakathi nenqubo yokukhiqiza kuzophinde kuthinte okuqukethwe komlotha we-cellulose

(5) Ukuze kudideke umbono wawo wonke umuntu, abanye abakhiqizi bazofaka isivinini somlilo kuwo, futhi ngeke kube nomlotha ngemva kokushiswa.Ishisa ngokugcwele, kodwa umbala ngemva kokuvutha usahluke kakhulu kulowo wempushana ehlanzekile.

Okwesibili: ubude besikhathi sokushiswa:

I-Cellulose enezinga elihle lokugcinwa kwamanzi izoshisa isikhathi eside uma kuqhathaniswa, futhi ngokuphambene nalokho ngenani eliphansi lokugcina amanzi.
