Ungawugweba njani umgangatho weselulosi kumxholo wothuthu lwe-hydroxypropyl methylcellulose emva kokutshiswa

Okokuqala, kufuneka siqonde ukuba yintoni uthuthu:

01. Isiqulatho sothuthu sikwabizwa ngokuba yintsalela evuthayo, enokuqondwa ngokulula njengobumdaka kwimveliso. Iya kuveliswa ngokwemvelo ngexesha lenkqubo yokuvelisa. Emva kokuba imveliso iphuma kwi-reactor etherification, iya kungena kwi-tank neutralization. Kwitanki ye-neutralization, ixabiso le-pH liqala ukulungiswa ukuba lingathathi hlangothi, kwaye emva koko amanzi ashushu afakwe ukuhlamba. Amanzi ashushu ngakumbi afakwe , Ukuhlamba, amaxesha amaninzi okuhlamba, ukuthoba umxholo womlotha, kwaye ngokuphambene noko.

02. Ubungakanani bomlotha bubuye bubonakaliswe ekuhlambulukeni kwe-cellulose, ukuphakama kobunyulu, kuncinci umlotha emva kokutshisa!

Okulandelayo, makhe sihlalutye ulwazi esilufumanayo kwinkqubo yokutshisa i-hydroxypropyl methylcellulose.

Eyokuqala: Ukuncipha kothuthu, kokukhona umgangatho uphezulu

Izigqibo zesixa sentsalela yothuthu:

(1) Umgangatho we-cellulose ekrwada (umqhaphu osulungekisiweyo): Ngokuqhelekileyo, ungcono umgangatho womqhaphu osulungekileyo, i-whiter cellulose eveliswayo, ngcono umthamo wothuthu kunye nokugcinwa kwamanzi.

(2) Inani lamaxesha okuhlamba: kuya kubakho uthuli kunye nokungcola kwizinto eziluhlaza, amaxesha amaninzi okuhlamba, amancinci amancinci emveliso egqityiweyo emva kokutshisa.

(3) Ukongeza izinto ezincinci kwimveliso egqityiweyo kuya kubangela ubuninzi bomlotha emva kokutshisa

(4) Ukungaphumeleli ukusabela kakuhle ngexesha lenkqubo yokuvelisa kuya kuchaphazela umxholo womlotha we-cellulose

(5) Ukuze kubhideke imbono yomntu wonke, abanye abavelisi baya kongeza isantya sokutshisa kuyo, yaye akuyi kubakho phantse luthuthu emva kokutshiswa. Itshisa ngokupheleleyo, kodwa umbala emva kokutshisa usahluke kakhulu kumgubo ococekileyo.

Okwesibini: ubude bexesha lokutshisa:

I-Cellulose enezinga elihle lokugcinwa kwamanzi liya kutshisa ixesha elide, kwaye ngokuphambene noko kumlinganiselo ophantsi wokugcinwa kwamanzi.
