I-Hydroxypropylm methylcellulose indlela yokuqothula

I-Hydroxypropyl methylcellulose, eyaziwa nangokuthi i-HPMC, i-ether engekho iselfose Kuyimpuphu emhlophe noma ephuzi kancane, inyakazisa kalula emanzini. Ake sixoxe ngendlela yokuqothula ye-hydroxypropyllylylyly methylcellulose.

Indlela / Isinyathelo
Okokuqala, i-hydroxypropyl methylcellulose isetshenziswa ikakhulukazi njengesengezo se-putty powder, udaka ne-glue. Uma ungezwe ku-usimende kasimende, ungasetshenziswa njenge-ejenti yokugcina amanzi kanye ne-retarder ukwandisa ukuncipha; Uma kungezwe ku-putty powder ne-glue, ingasetshenziswa njenge-binder. Ukuze uthuthukise ukusakazeka bese welula isikhathi sokusebenza, ake sithathe i-Qingquan Cellulose njengesibonelo sokuchaza indlela yokuchithwa kwe-hydroxypropylylylylyl.

I-hydroxyproppropylyrpropylyll methylcellulose iqhutshwa okokuqala futhi ihlakazeke ngamanzi ashisayo, yabe isichithwa ngokungeza amanzi abandayo, ivuse futhi ipholile;

Ngokuqondile: Thatha i-1 / 5-13 yenani elidingekayo lamanzi ashisayo, uvuse ukwenza umkhiqizo ongeziwe uvuvukale ngokuphelele, bese ufaka ingxenye esele yamanzi ashisayo, noma amanzi eqhwa, futhi uvuse amazinga okushisa afanele (10 ° C) ukuncibilikisa ngokuphelele.

Indlela ye-Organic solvent ye-solvent:

Shiya i-hydroxypropyll methylcellulose ku-organic solvent noma umanzisa i-organic solvent, bese uyifaka emanzini abandayo noma engeza amanzi abandayo, ingancibilika kahle, futhi i-organic solcent ingaba yi-ethanol, ethylene glycol, njll.

4
Uma kukhona i-agglomeration futhi ukugoqa ngesikhathi sokuchithwa, kungenxa yokuthi ukushukumisela akwanele noma imodeli ejwayelekile ingezwe ngqo emanzini abandayo. Ngalesi sikhathi, kufanele kuvuswe ngokushesha.

5
Uma ama-bubble akhiqizwa ngesikhathi sokuchithwa, kungashiywa amahora angama-2-12 (isikhathi esithile sinqunywa ngokuvumelana kwesisombululo) noma sisuswe ngokuvalwa, ukucindezela, noma ukungeza inani elifanele le-ejenti yokungcolisa.

Ukugcina
Izinyathelo zokuzivikela
I-Hydroxypropyllykyl methylcellulose ihlukaniswe ngohlobo olunciphisayo nohlobo olususiwe olusheshayo. I-hydroxyproppropyllose esheshayo esuswa manjalo ingancibilika ngqo emanzini abandayo.
