Mmodzi wa ubwino waukulu ntchito HPMC monga thickener ndi kuti akhoza thicken yankho popanda kukhudza momveka bwino kapena mtundu. HPMC ndi polima sanali ionic, kutanthauza kuti sapereka mlandu uliwonse yankho. Izi zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito popanga zomveka bwino kapena zowonekera.
Ubwino wina wa HPMC ndikuti imatha kukulitsa mayankho pamlingo wochepa. Izi zikutanthauza kuti pang'ono chabe HPMC chofunika kukwaniritsa makusulidwe ankafuna. Izi zitha kupulumutsa ndalama kwa opanga ndikupatsa makasitomala zinthu zotsika mtengo.
Thixotropy of HPMC
Thixotropy ndi katundu wa zinthu zochepetsera kukhuthala pamene akukhudzidwa ndi kumeta ubweya ndikubwerera ku maonekedwe ake oyambirira pamene kupanikizika kumachotsedwa. HPMC ndi zinthu za thixotropic, kutanthauza kuti zimafalikira kapena kutsanulira mosavuta pansi pa kumeta ubweya wa ubweya. Komabe, kupsinjikako kukachotsedwa, kumabwereranso kumamatira ndikukhuthalanso.
The thixotropic zimatha HPMC kupanga kukhala abwino kwa ambiri ntchito. Mwachitsanzo, nthawi zambiri amagwiritsidwa ntchito mu utoto, ngati malaya okhuthala pamwamba. The thixotropic zimatha HPMC kuonetsetsa kuti ❖ kuyanika amakhalabe pamwamba popanda sagging kapena kuthamanga. HPMC imagwiritsidwanso ntchito m'makampani azakudya ngati chowonjezera cha sosi ndi zovala. The thixotropic katundu wa HPMC kuonetsetsa kuti sauces kapena mavalidwe si kudontha kuchokera spoons kapena mbale, koma kukhala wandiweyani ndi zogwirizana.
HPMC ndi polima zosunthika ndi ntchito zambiri m'mafakitale osiyanasiyana. Zake thickening katundu ndi thixotropic katundu kupanga izo abwino zodzoladzola, mankhwala ndi chakudya formulations. HPMC ndi thickener kwambiri, kuwonjezera mamasukidwe akayendedwe a yankho popanda kukhudza kumveka kwake kapena mtundu. Makhalidwe ake a thixotropic amaonetsetsa kuti yankho lisakhale lakuda kwambiri kapena lochepa kwambiri, malingana ndi ntchito. HPMC ndizofunikira kwambiri pazogulitsa zambiri, ndipo maubwino ake ambiri zimapangitsa kukhala chisankho chodziwika kwa opanga ndi makasitomala.
