HPMC, yomwe imadziwikanso kuti hydroxpyl methylcellulose, ndi polymer-solid polojekiti yomwe imagwiritsidwa ntchito kwambiri podzikongoletsa, mafakitale am'madzi. Polymer amachokera ku cellulose, chinthu chachilengedwe chimapezeka muzomera. HPMC ndichabwino kwambiri otsatsa kwambiri omwe amagwiritsidwa ntchito kwambiri kuti muwonjezere mawonekedwe a mayankho osiyanasiyana. Kutha kwake kutulutsa ma gelsic tatific kumapangitsanso chisankho chotchuka mu ntchito zambiri.
Katundu wa hpmc
Kuchulukitsa kwa HPMC kumadziwika bwino m'makampaniwo. HPMC imatha kuwonjezera mafayilo a yankho popanga gel network yomwe imapopera mamolekyulu amadzi. Tinthu tambiri tokhala ndi gel net net nelt mukamayamwa madzi ndikukopa wina ndi mnzake kudzera pamalanda a hydrogen. Network imapanga matrix atatu omwe amawonjezera mafayilo a yankho.
Chimodzi mwazopindulitsa kwambiri pakugwiritsa ntchito HPMC ngati Thicker ndikuti imatha kukula pang'ono osakhudza kumveka kwake kapena mtundu. HPMC ndi polymer yopanda ionic, yomwe imatanthawuza kuti sizipereka ngongole iliyonse pa yankho. Izi zimapangitsa kukhala koyenera kugwiritsa ntchito mawonekedwe owoneka bwino kapena owonekera.
Ubwino wina wa hpmc ndikuti amatha kukula bwino pamavuto otsika. Izi zikutanthauza kuti mtengo wochepa chabe womwe umafunikira kuti ukwaniritse ma virus. Izi zitha kupulumutsa ndalama zopanga ndikupereka makasitomala omwe ali ndi chuma chambiri.
Thixotropy ya hpmc
Thixotropy ndi katundu wazinthu zochepetsera ma visc Confc mukamagwera kupsinjika ndikubwerera ku mawonekedwe ake oyambira pomwe nkhawa imachotsedwa. HPMC ndi nkhani ya thixotropic, kutanthauza kuti imafalikira kapena kuthirira mosavuta m'mitsempha. Komabe, kupsinjika kumachotsedwa, kumabweranso kumalire ndi kukuliranso.
Katundu wa HIXOTOPIC ya HPMC imapangitsa kuti zikhale zabwino pazomwe zimagwiritsidwa ntchito. Mwachitsanzo, nthawi zambiri amagwiritsidwa ntchito pa utoto, ngati chovala chakuda pamwamba. Katundu wa hixotropic ya hpmc onetsetsani kuti zokutidwazo zimakhala pansi osakugwa kapena kuthamanga. HPMC imagwiritsidwanso ntchito makampani ogulitsa zakudya ngati thickener ya msuzi ndi mavalidwe. Katundu wa HPMECIC ya HPMC onetsetsani kuti sungu kapena mavalidwe sakugwa kuchokera pa smons kapena mbale, koma m'malo mokhala ndi pakati komanso kosasinthasintha.
HPMC ndi polymer yosiyanasiyana ndi ntchito zambiri m'mafakitale osiyanasiyana. Katundu wake wokulirapo ndi thixotropic katundu amapangitsa kuti zikhale zabwino kwa cosmetic, mankhwala opangidwa ndi chakudya. HPMC ndichabwino kwambiri, ndikuwonjezera mafayilo osakhudza kumveka kwake kapena mtundu. Malo ake a thixotropic yake akuwonetsetsa kuti yankho silikhala lolimba kapena lochepa kwambiri, kutengera ntchito. HPMC ndi chofunikira mu zinthu zambiri, ndipo zopindulitsa zake zambiri zimapangitsa kuti ikhale chisankho chotchuka kwa opanga opanga ndi makasitomala.
