HPMC cyangwa HEC: Guhitamo Icyiza Cyiza Cyiza Cyiza Cyamabara

Ku bijyanye n'irangi rishingiye ku mazi, guhitamo kubyimbye birashobora kugira ingaruka zikomeye ku mikorere y'ibicuruzwa, cyane cyane mu gihe cy'izuba kirangwa n'ubushyuhe bwinshi. ByombiHydroxypropyl Methyl Cellulose (HPMC)naHydroxyethyl Cellulose (HEC)byagaragaye nkibikoresho bizwi cyane mubikorwa byo gusiga amarangi kubera imiterere yihariye n'imbaraga zitandukanye. Izi selile ziyongera, zitangwa namasosiyete nkaJINJI CHIMICAL, babonye porogaramu nini kubera imiterere yabo itandukanye. Nyamara, icyemezo hagati ya HPMC na HEC amaherezo biterwa nibisabwa byihariye byo gushushanya amarangi no kubigenewe.

Gusobanukirwa HPMC na HEC

HPMC na HEC byombi ni polymer-soluble polymers ikomoka kuri selile, izwiho ubushobozi bwo guhinduraububobere,rheologiya, naimiterere ya firimeamarangi. Nuburyo bukoreshwa mubisanzwe, berekana imiterere yimiti itandukanye nibiranga bigira ingaruka kubikorwa byabo byihariye.

Hydroxypropyl Methyl Cellulose (HPMC)

HPMC ni selile ya ether hamwe na hydroxypropyl na methyl matsinda, itangaamazi meza cyanenaituzemuri sisitemu y'amazi.

Itanga umubyimba ukomeye kandi uhamye, bigatuma biba byiza mugushushanya amarangi hamweimiterere, ihamye. Ikigaragara, HPMC irerekanaimyitwarire ya thermogel.impuzu zo hanze.

Ubusugire bwa firime ya HPMC buguma butajegajega munsi yizuba rirerire bitewe nubushobozi bwayo bwo gushimangira inzitizi yumubiri ya materique yo gutwikira, nubwo idakunze kwinjiza imirasire ya UV.

Hydroxyethyl Cellulose (HEC)

Itsinda rya hydroxyethyl mumiterere ya molekulari ya HEC irabihanziza cyaneg naibikoresho byo kubika amazi, cyane cyane mubushyuhe bwo hagati hamwe nubushuhe buhebuje bwibidukikije, bigatuma biba ibikoresho byo guhitamoimberenaibintuibyobisaba ibintu byiza cyane. Bitandukanye na HPMC, HEC ntabwo ikora thermogels kandi irashobora gutakaza ubukonje bwubushyuhe bwo hejuru (> 60 ° C).

HEC ifitebiostability nzizakandi ikabuza gukura muburyo bukemutse. Nyamara, imiterere yimiti ikora cyane cyane mukugabanya kwibasirwa na mikorobe muri sisitemu yo gutwikira. Kugera kurinda igihe kirekire kurinda mikorobe hamwe na biostability yonyine ni diffcult. Kubwibyo, kubungabunga ibidukikije (urugero, Kathon, MIT, nibindi) bigomba kongerwaho kote kugirango hubakwe uburyo burambye bwo kwirinda mikorobe. Ubushakashatsi bwerekanye koHEC ikora neza kurusha HPMC mukwongerera igihe cyo gutwikiraiyo ikoreshejwe hamwe nuburinzi.

Kugereranya: HPMC na HEC: Hitamo igikwiye kumushinga wawe

Urebye itandukaniro ryimiti, HPMC na HEC bagaragaza ibyiza nibibi bidasanzwe mugukoresha amarangi ashingiye kumazi, cyane cyane mubihe by'ubushyuhe bwo hejuru busanzwe mubihe byizuba.

1. Imikorere mubushyuhe bwo hejuru

-HPMC: Imurikagurishaimyitwarire ya thermogellingku bushyuhe bwo hejuru (50 ° C - 90 ° C), aho iva mu gisubizo ikagera kuri agel, kuzamuraububoberenaKurwanya urubanzaahantu hashyushye cyane(urugero, impuzu zo hanze zikoreshwa mu ci).Ubusugire bwa firime bukomeza kuba bwiza munsi yizuba ryinshi nubushyuhe.

-OYAAcks Kubura ubushyuhe bwumuriro kandi birashobora kugabanya cyane ubukonje bwubushyuhe buri hejuru ya 60 ° C. Ariko, ikora neza mubushyuhe bwo hagati(urugero: ibidukikije byo mu nzu cyangwa ibihe byinshi byo hejuru)- ntabwo ifite gusagufata neza amazinta kwangirika k'ubushyuhe, ariko kubika amazi menshi nabyoyongerera igihe cyo gufungura, kwemerera abakozi gukora ibintu birebire mugihe bazunguruka cyangwa koza ahantu hanini.

2. Uburyo bwo gusaba no gukora neza

-HPMC： Mu bushyuhe bwo hejuru bwo hanze, HPMC yerekana kuringaniza bidasanzwe no gukora firime. Yayoumutungo wa thermogelationyihutauburyo bwo kumishamugihe utangaimikorere irwanya sagkugeza impeshyi.Ndetse no munsi yizuba ryinshi, ingaruka ya thermogelation ituma firime yihuta, ikemeza ubwiza bwubuso buhoraho kandi bikazamura imikorere ya firime muri rusange.

-OYA： Kuba indashyikirwa mu nzu cyangwa mu kirere giciriritse, gutangaGushyira mu bikorwanakubika amazi mezaigihe kinini cyo gufungura(urugero,inirangi rya latx). Ubushyuhe bwacyo bugabanya ubukana igihe kinini cyo guhura nubushyuhe bukabije.

Guhitamo Ibikwiye: Umukiza wawe wimpeshyi

Guhitamo hagati ya HPMC (Hydroxypropyl Methyl Cellulose) na HEC (Hydroxyethyl Cellulose) amaherezo biva kubisabwa byihariye hamwe nibidukikije byerekeranye no gusaba.

Kubisabwa hanze cyangwa ubushyuhe bwo hejuru bwizuba,HPMCni Byahiswemo kubera iumutungo wa thermogelation, ifasha gukama vuba, irinda kugabanuka mugihe cyo kuyikoresha, kandi ikanemeza ituze munsi yubushyuhe bwo hejuru. Ubushobozi bwayo bwo gukora gele mubushyuhe buringaniye-hejuru (50 ° C - 80 ° C) byihutisha imiterere ya firime, bigatuma biba byiza mubihe bisaba gukira vuba no kurwanya ubushyuhe buterwa nubushyuhe.

Ibinyuranye,murugo cyangwa kugenzura ibidukikije hamwe nubushyuhe buke,OYAitanga ibyiza bitandukanye. Yayokubika amazi mezaubushobozi bwongerera igihe cyo gufungura no guhinduranya mugihe cyo gutwikira, mugihe imiterere yimiti (iyo ihujwe nuburinzi) igabanya mikorobe, igahindura imiterere kandi ikabuza gukura kwa mikorobe. Ibi bituma HEC ikwiranye neza na porogaramu ishyira imbere gukora firime hamwe no kurwanya mikorobe ndende mugihe giciriritse.

Umwanzuro

Ibicuruzwa bya HPMC na HEC bya JINJI CHEMICAL bitanga ibisubizo byihariye: Ubushyuhe bwa HPMC bwihuta bwumisha kandi bikarinda kugabanuka mubushyuhe bwinshi, bigatuma firime yihuta; HEC yongerera igihe ifunguye hamwe no gufata amazi meza kandi ikongerera mikorobe iyo ihujwe nuburinzi, nibyiza kubidukikije cyangwa bigenzurwa. Mugupima ibintu nkibisabwa, imiterere ya firime, nigihe kirekire. GuhitamoUMUKOBWAHPMCnaOYA Yemeza ko impuzu zawe zigumya kurangiza neza nigihe kirekire ndetse no mubihe byizuba bikabije, bikarinda ubwiza nibikorwa.
