I-Hydroxypropyll methylcellulose icishe ibe yi-ethanol ngokuphelele ne-acetone. Isixazululo samanzi sizinze kakhulu ekushiseni kwegumbi futhi singakwazi ukufumeka okuphezulu. Iningi le-hydroxypropyll methylcellulose emakethe manje elingamanzi abandayo (amanzi okushisa egumbi, amanzi ompompi) uhlobo olusheshayo. I-HPMC enamanzi ebandayo i-HPMC izoba lula futhi iphephe kakhulu ukuyisebenzisa. I-HPMC idinga ukuthi ingezwe ngqo kwikhambi lamanzi abandayo ngemuva kwemizuzu eyishumi kuya kwamashumi ayisishiyagalolunye ukuze ikhule kancane kancane. Uma kuyimodeli ekhethekile, idinga ukushukunyiswa ngamanzi ashisayo ukuhlakazeka, bese ithuthela emanzini abandayo ukuncibilikisa ngemuva kokupholisa.
Lapho imikhiqizo ye-HPMC ingezwe ngqo emanzini, izohamba bese ichithwa, kepha lokhu kuchithwa kuhamba kancane futhi kunzima. Kunconywa izindlela ezintathu zokuchithwa kwezindlela, futhi abasebenzisi bangakhetha indlela elula kakhulu ngokuya ngesimo sokusebenzisa (ikakhulukazi i-HPMC ebandayo esheshayo ye-HPMC).
Indlela yokuqothula kanye nokuqapha kwe-HPMC
1. Indlela yamanzi ebandayo: lapho idinga ukufakwa ngqo kwisisombululo esijwayelekile samanzi samanzi okushisa, kungcono ukusebenzisa uhlobo lokuhlakazeka kwamanzi olubandayo. Ngemuva kokungeza i-viscosity, ukuvumelana kuzokwenyuka kancane kancane kwisidingo senkomba.
2 Eqinisweni, noma ngabe hlobo luni lwe-hydroxypropyll methylcellulose. Ingenziwa ihlanganiswe ngqo kwezinye izinto.
I-3. Indlela ye-Organic Solvent ye-Organic: I-HPMC ihlakazeke ngaphambili noma ifakwe ngama-solvents ezi-organic, njenge-ethanol, i-ethylene glycol noma uwoyela, bese ichithwa futhi emanzini, futhi bese kuncibilikiswa.
Ngesikhathi senqubo yokuqothula, uma kukhona i-agglomeration, izogoqwa. Lokhu kungumphumela wokuvuselelwa okungalingani, ngakho-ke kuyadingeka ukusheshisa ijubane lokuvusa. Uma kukhona ama-bubble ekuchithweni, kungenxa yomoya obangelwa ukuvuselelwa okungalingani, futhi isixazululo sivunyelwe ukuma amahora angama-2- (isikhathi esithile sincike ekuvumelaneni kwesixazululo) noma ukucindezela kanye nezinye izindlela Ukususa, ukwengeza inani elifanele le-defoomer nakho kungasusa lesi simo. Ukungeza inani elifanele le-defoamer nakho kungasusa lesi simo.
Njengoba i-hydroxypropylllylyl isetshenziswa ezimbonini ezahlukahlukene, kubaluleke kakhulu ukuze ukwazi kahle indlela yokuchithwa kwe-hydroxypropylylylylylyllllose methylcellulose ngokusetshenziswa kwayo okulungile. Ngaphezu kwalokho, abasebenzisi bakhunjuzwa ukuthi banake ukuvikela ilanga, ukuvikela kwemvula kanye nokuvikelwa komswakama ngesikhathi sokusetshenziswa, Gwema ukukhanya okuqondile, bese ugcina endaweni ebekwe uphawu neyomile. Gwema ukuxhumana nemithombo yokulahla futhi uvikele ukwakheka kwamanani amakhulu othuli ezindaweni ezivalekile ukuvikela izingozi zokuqhuma.
