HydroxyPropyl Methylcellse (HPMC)ni amazi ya polymer ya synthesied ukurikije molekile ihindura molekile. Ihuza imitungo karemano ya selile hamwe nuburyo bwahinduwe, bifite amazi meza, hakoreshwa amashusho yubusa, kandi ikoreshwa cyane mumiti, kwisiga, kubaka, ibiryo nibindi bice. Ikiganiro kijyanye no niba ari igisubizo gikeneye kugirango gitandukane porogaramu nimiterere yihariye mumirima itandukanye.
Imiterere yimiti numutungo wa HydroxyPropyl methylcellse
HPMC yateguwe mu kumenyekanisha amatsinda abiri asimbuye, hydroxyPropyl (-ch2ch (OH) na methyl (-ch3), mu gice cya glucose cya molekile ya selile. Molekile ya selile ubwayo ni umunyururu muremure cyane ugizwe na molekile nyinshi zahujwe na β - 1,4-glycosic.
Mugihe cya synthesis, ubwibumbe butuma molekile ya selile ya lipophilic, mugihe hydroxy oplepypyley Binyuze muri ibyo bisobanuro byombi, HPMC ihinduka urugomo rushobora guhinduka rushobora gushonga mumazi.
Kwitonda n'imikorere ya HPMC
HPMC ifite neza cyane mumazi, cyane cyane mumazi ashyushye. Ubwo ubushyuhe buzamutse, igipimo cy'imivugo no kukesha kwiyongera. Ariko, HPMC ubwayo ntabwo isanzwe "igisubizo", ariko ikoreshwa nkigisubizo cyangwa ikibyimba. Mu mazi, irashobora gukora igisubizo cya colloidal binyuze mubikorwa hamwe na molekile y'amazi, bityo ihindura viscosity na rheologiya yigisubizo.
Nubwo HPMC ishobora gushonga mumazi, ntabwo ifite imitungo ya "solve" muburyo gakondo. Ibicuruzwa bisanzwe mubisanzwe bimara gushonga ibindi bintu, nkamazi, alcool, ketones cyangwa andi mashanyarazi. Iseswa rya HPMC ubwaryo mumazi ni ibintu bikora byimikorere yo kubyimba, gutengurira no gushiraho firime.
Gusaba imirima ya HPMC
Umwanya w'ubuvuzi: HPMC ikunze gukoreshwa nk'igituba cy'ibiyobyabwenge, cyane cyane mu gutegura impapuro zidasanzwe zo mu magambo (nk'ibinini na capsules), cyane cyane bikoreshwa mubyimbye, kumeneka, gushiraho filimi nibindi bikorwa. Irashobora kunoza ibinyabuzima bya bioakwaiLowaility kandi nabyo ikoreshwa mugutegura kwitegura kugirango bifashe kugenzura irekurwa ryibiyobyabwenge.
Umwanya wo kwisiga: HPMC ikoreshwa cyane mubicuruzwa byita ku ruhu, shampoo, mask yo mu musatsi, amavuta y'amaso n'andi mavuta yo kwisiga nk'uburebure, stabilizer na agent-filme. Uruhare rwarwo mugutanga cyane cyane kugirango wongere umutekano nuburyo bwibicuruzwa kandi bikongere neza.
Umwanya wubwubatsi: Mu nganda zubwubatsi, HPMC ikoreshwa nkuwabyimbye kandi ikwirakwiza muri sima, mirisiteri yumye, irangi nibindi bicuruzwa. Irashobora kongera viscolity yirangi, kunoza imikorere yubwubatsi no kwagura igihe cyubwubatsi.
Umwanya w'ibiribwa: HPMC ikoreshwa nk'ibiribwa, cyane cyane bikoreshwa mubyimbye, kwiyongera no kunoza uburyohe, kandi bikunze kuboneka muburyo buke, bombo na ice cream na ice cream. Byongeye kandi, irashobora kandi gukoreshwa mugutezimbere imiterere, uburyohe nubushya bwibiryo.
Gusaba nkibintu
Muburyo bumwe bwihariye bwo kwitegura, HPMC irashobora kandi gukoreshwa nkigice gifasha cyoroshye. Kurugero, murwego rwumuti wa farumasi, abatunguye ba HPMC bituma ikoreshwa nka dilubizer cyangwa soflizer zimwe na zimwe mu myiteguro y'ibiyobyabwenge, cyane cyane mu myiteguro y'amazi, cyane cyane mu myiteguro y'amazi, aho ishobora gufasha neza ibiyobyabwenge kandi bikaba igisubizo kimwe.
Mu mavuta amwe n'amwe ashingiye ku mazi,HpmcIrashobora kandi gukoreshwa nkumukozi wungirije kugirango ukemure imitungo hamwe nibikorwa byimikorere ya moshi, nubwo ikintu nyamukuru cyo gupfukirana mubusanzwe ari amazi cyangwa ibinyabuzima.
Nubwo HPMC ishobora gushonga mumazi muri porogaramu nyinshi kugirango ikore colloid cyangwa igisubizo kandi yongere viscosiya namazi yibisubizo, ubwayo ntabwo ifatwa nkigisubizo gakondo. Ahubwo, birakunze gukoreshwa nkibintu bikora nkumubyimba, umukozi wa dolling, hamwe numukozi wa firime. Ifite uburyo butandukanye bwo gusaba mumirima itandukanye, cyane cyane muri farumasi, kwisiga, ibiryo, hamwe nubwubatsi. Kubwibyo, mugihe usobanukiwe nuruhare numutungo wa HPMC, bigomba gufatwa nkinyama nyinshi zo gukosora amazi aho kuba igisubizo cyoroshye.
