Indlela yokuncibilikisa i-Hydroxypropyl methylcellulose HPMC

I-Hydroxypropyl methylcellulose, eyaziwa nangokuthi i-HPMC, iyi-nonionic cellulose ether etholakala kukotini ocolisisiwe, into yemvelo ye-polymer, ngokusebenzisa uchungechunge lwezinqubo zamakhemikhali. Iyimpuphu emhlophe noma ephuzi kancane encibilika kalula emanzini. Ake sixoxe ngendlela yokuncibilikisa i-hydroxypropyl methylcellulose.

1. I-Hydroxypropyl methylcellulose isetshenziswa kakhulu njengesithako se-putty powder, i-mortar kanye ne-glue. Uma ingezwa ku-cement mortar, ingasetshenziswa njenge-ejenti yokugcina amanzi kanye ne-retardant ukwandisa ukumpompa; uma ingezwa ku-putty powder kanye ne-glue, ingasetshenziswa njenge-binder. Ukuze sithuthukise ukusabalala nokwandisa isikhathi sokusebenza, sithatha i-Qinngquan Cellulose njengesibonelo ukuchaza indlela yokuncibilikisa i-hydroxypropyl methylcellulose.

2. I-hydroxypropyl methylcellulose evamile ivuselelwa kuqala bese isakazwa ngamanzi ashisayo, bese ingezwa ngamanzi abandayo, ivuselelwe bese ipholiswa ukuze incibilike;

Ngokuqondile: thatha i-1/5-1/3 yenani elidingekayo lamanzi ashisayo, uvuselele kuze kube yilapho umkhiqizo owengeziwe uvuvukele ngokuphelele, bese ufaka ingxenye esele yamanzi ashisayo, okungaba amanzi abandayo noma ngisho namanzi eqhwa, bese uvuselela ekushiseni okufanele (10°C) kuze kube yilapho uncibilika ngokuphelele.

3. Indlela yokumanzisa isinyibilikisi se-organic:

Hlakaza i-hydroxypropyl methylcellulose ku-solvent ephilayo noma uyimanzise nge-solvent ephilayo, bese ufaka noma wengeze amanzi abandayo ukuze uyincibilikise kahle. I-solvent ephilayo ingaba yi-ethanol, i-ethylene glycol, njll.

4. Uma kwenzeka ukuhlangana noma ukugoqa ngesikhathi sokuncibilika, kungenxa yokuthi ukuxuba akwanele noma imodeli evamile ifakwa ngqo emanzini abandayo. Kuleli qophelo, hlanganisa ngokushesha.

5. Uma amabhamuza ekhiqizwa ngesikhathi sokuncibilika, angashiywa amahora angu-2-12 (isikhathi esithile sincike ekuqineni kwesisombululo) noma asuswe ngokufaka u-vacuum, ukucindezela, njll., noma ngokungeza inani elifanele le-ejenti yokuhlanza.

Izinyathelo zokuzivikela

I-hydroxypropyl methylcellulose ihlukaniswe ngezinhlobo ezincibilika kancane kanye nezinhlobo ezincibilika ngokushesha. I-hydroxypropyl methylcellulose esheshayo ingancibilika ngqo emanzini abandayo.
