Imvugo no guhuza hydroxypropyl methylcellulose (HPMC) hamwe na hydroxypropyl krahisi (HPS) bigira uruhare runini mubikorwa bitandukanye, harimo imiti, ibiryo, amavuta yo kwisiga, nubwubatsi.Gusobanukirwa imikoranire iri hagati yizi polymers zombi ningirakamaro mugutezimbere imikorere yabo no guteza imbere ibicuruzwa bishya.Uru rupapuro rugamije gucukumbura imiterere ya rheologiya no guhuza ibikorwa bya HPMC / HPS.
Imiterere ya Rheologiya:
Rheologiya nubushakashatsi bwukuntu ibikoresho bihinduka kandi bigatwarwa nimbaraga ziva hanze.Kubireba urwego rwa HPMC / HPS, imiterere ya rheologiya igena ubwiza, imyitwarire ya gelation, hamwe nibintu byose bitemba bya polymer.Imyitwarire ya rheologiya yikigo irashobora guterwa nibintu nko kwibanda kuri polymer, uburemere bwa molekile, ubushyuhe, nigipimo cyogosha.
Guhuza HPMC na HPS:
Guhuza hagati ya HPMC na HPS ni ngombwa kugirango habeho ishyirwaho ryimiterere ihamye hamwe nibintu byifuzwa.Guhuza bivuga ubushobozi bwa polimeri ebyiri cyangwa nyinshi zo kuvanga no gukora sisitemu ya homogeneous nta gutandukanya icyiciro cyangwa gutakaza imikorere .. Guhuza HPMC na HPS birashobora guterwa nuburyo bwimiti yabyo, uburemere bwa molekile hamwe nuburyo bwo gutunganya.
Ibintu bigira ingaruka kumvugo no guhuza:
Ikigereranyo cya polymer: Ikigereranyo cya HPMC na HPS murwego rugoye kirashobora kugira ingaruka zikomeye kumiterere yacyo ya rheologiya no guhuza .. Ibipimo bitandukanye birashobora gutuma habaho ubukana butandukanye, imbaraga za gel, hamwe nimyitwarire.
Uburemere bwa molekuline: Uburemere bwa molekuline ya HPMC na HPS bugira ingaruka kuri rheologiya no guhuza ibigo .. Uburemere buke bwa molekile butera kwiyongera kwijimye no kongera imiterere ya gelation.
Ubushyuhe: Ubushyuhe urwego rwateguwe kandi rusuzumwa bigira ingaruka kumyitwarire ya rheologiya .. Guhindagurika kwubushyuhe birashobora gutuma habaho gutandukana kwicyiciro cyangwa guhindura imikoranire ya polymer, biganisha ku guhinduka kwijimye no kwizana.
Igipimo cyogosha: Igipimo cyogukoresha mugihe cyo kugerageza cyangwa gutunganya birashobora kugira ingaruka kumiterere yimiterere yikigo cya HPMC / HPS.Igipimo cyo hejuru cyogosha gishobora kuganisha kumyitwarire-yogosha, aho ubwiza bugabanuka hamwe no kwiyongera kwimyenda.
Porogaramu:
Imvugo no guhuza uruganda rwa HPMC / HPS bifite uruhare runini mu nganda zinyuranye .. Mu miti y’imiti, inganda zirashobora gukoreshwa mu guhindura irekurwa ry’ibiyobyabwenge, kuzamura umutekano, no kurwanya ubukonje .. Mu nganda z’ibiribwa n’amavuta yo kwisiga, birashobora gukoreshwa nkumubyimba, stabilisateur, cyangwa emulifier.Mubikoresho byubwubatsi, ibigo birashobora kunoza imikorere no guhuza sisitemu ya sima.
Rheologiya no guhuza ibigo bya HPMC / HPS nibitekerezo byingenzi mugutezimbere imikorere yabyo mubikorwa bitandukanye .. Gusobanukirwa ningaruka ziterwa nibintu nka polymer igipimo, uburemere bwa molekile, ubushyuhe nigipimo cyogosha ningirakamaro mugushushanya ibyingenzi bifite imiterere ya rheologiya .. Ubundi bushakashatsi n'iterambere muri kano karere birashobora kuganisha ku guhanga ibicuruzwa bishya bifite imikorere inoze ndetse no kunoza imikorere mu nganda nyinshi.
