IHydroxypropyll Methylcellulose (HPMPC) isetshenziswa kabanzi ezintweni zokwakha, izimbobo, ama-desin zokwenziwa, ubumba - ubumba, ubuciko, izindwangu, ugwayi kanye nezinye izimboni. I-Hydroxypropyl Methyl Cellulose (HPMC) yi-ether engekho i-ether ether etholwe kwi-polymer mattize yemvelo ngochungechunge lokucutshungulwa kwamakhemikhali. I-Hydroxypropyl Methylcellulose (HPMC) iyimpuphu, engenabutha, engenamkhawulo, i-nontoxic white powder engachithwa emanzini abandayo ukwakha isixazululo esibonakalayo se-vispent. Inezakhiwo zokuqina, ukubopha, ukusabalalisa, ukusabalalisa, ukwakha amafilimu, ukumisa amafilimu, ukumisa ama-adsorbing, ukugada, indawo esebenzayo, ukugcina umswakama nokuvikela umswakama nokuvikela ama-colloids.
Indlela yokuchithwa kwe-hydroxypropyllylylylyl (hpmc):
Lo mkhiqizo uvunguza futhi uhlakaze emanzini ashisayo ngenhla kwama-85 ° C, futhi uvame ukuchithwa yizindlela ezilandelayo:
1. Thatha u-1/3 wenani elidingekayo lamanzi ashisayo, uvuse ukuze uchithe ngokuphelele umkhiqizo ongeziwe, bese ufaka ingxenye esele yamanzi ashisayo, angaba ngamanzi abandayo noma amanzi eqhwa, bese ugqugquzela ngokuphelele izinga lokushisa (20 ℃), khona-ke lingachithwa ngokuphelele.
2. Ukuhlanganiswa ngokomile:
Uma kwenzeka kuxubana namanye ama-powders, kufanele kuxutshwe kahle nabapopa
3. Indlela ye-organic solvent ye-solvent:
Okokuqala uhlakaze umkhiqizo ku-solvent ye-organic noma umanzisa nge-organic solvent, bese uyifaka emanzini abandayo, ingancibilika kahle.
