I-HPMC yokuhlelwa kunye nendlela yokuphelisa

1.Ukuchazwa:

I-HPMC inokwahlulwa kuba luhlobo lwangoko kunye nohlobo olushushu olushushu. Iimveliso zemodi zethutyana zisasaza ngokukhawuleza emanzini abandayo kwaye zinyamalala emanzini. Ngeli xesha, ulwelo alunanto yokufakwa, kuba i-HPMC ichithwa njengamanzi kwaye ayinasiphelo sokwenyani. Emva kwemizuzu emi-2, i-viscosity ye-ulwelo ngokuthe ngcembe yanda ukwenza i-collous engabonakaliyo. Iimveliso ezishushu ezishushu, xa zidibene namanzi abandayo, zinokusasazeka ngokukhawuleza emanzini ashushu kwaye inyamalale emanzini ashushu. Xa iqondo lobushushu liye kwehla kubushushu obuthile, i-vickosity ivela kancinci de i-vicous engabonakaliyo yenziwa. Uhlobo olushushu olushushu lunokusetyenziswa kuphela kwi-podty powder nodaka. Kwiglue yeglue kunye nepeyinti, ukubethwa kuka-Likedon kuya kwenzeka kwaye akunakusetyenziswa. Uhlobo lwethutyana lunoluhlu olubanzi lwezicelo. Ingasetyenziswa kwi-poceble yomgubo kunye nodaka, kunye neglu yolwelo kunye nepeyinti, ngaphandle kokuphikisana.

2.Indlela yokulinganisa:

Indlela eshushu yokuphelisa amanzi Iindlela ezimbini eziqhelekileyo zichazwe ngolu hlobo lulandelayo: 1), faka imali efunekayo kumanzi ashushu ashushu kwaye uvukile ukuya kuma-70 ° C. I-hydroxypropyl methylcelcelsulose yongezwa ngokuthe ngcembe, ekuqaleni i-HPMC ifakwe kumphezulu wamanzi, emva koko yazenzela ngokuthe ngcembe isilayidi. 2), Yongeza isixa esifunekayo se-1/3 okanye i-2/3 samanzi kwisitya, kwaye usitshise ukuya kwi-70 ° C, ngokusasaza i-HPMC, lungiselela amanzi ashushu. Emva koko yongeza inani elisele lamanzi abandayo ukuya kwamanzi ashushu kwi-slirry, umxube wapholwa emva kokuvuselela.

Indlela yokuxuba i-powder Indlela ye--tis isetyenziswa yi-putty powder kunye nabavelisi bodaka. [I-HYDROXYPPOPLL Methylcelcelsele (i-HPMC) isetyenziswa njenge-tickener kunye nearhente yokugcina amanzi kwi-putreder farrm
