Hydroxypropylmethylcellulose (HPMC) ndi polima wopangidwa ndi kusintha cellulose zachilengedwe. Ili ndi ntchito zosiyanasiyana zamafakitale muzamankhwala, chakudya, zodzoladzola, ndi zomangamanga. HPMC ndi nonionic cellulose ether yomwe imasungunuka mosavuta m'madzi ndipo imatha kupanga njira yowonekera, ya viscous yomwe imakhalabe yokhazikika pa pH yochuluka.
Makhalidwe a HPMC ndi awa:
1. Kuchuluka kwa madzi osungira madzi: HPMC imatha kuyamwa madzi ndikuwasunga m'malo mwake, kuwapangitsa kukhala othandiza monga thickener, emulsifier, ndi stabilizer mu ntchito zambiri.
2. Zinthu zabwino zopangira mafilimu: HPMC ikhoza kupanga mafilimu owonekera ndi mphamvu zamakina abwino. Izi zimalola kuti zigwiritsidwe ntchito popanga makapisozi, zokutira ndi zinthu zina.
3. Ntchito yapamwamba kwambiri: HPMC ili ndi zinthu zogwira ntchito pamtunda, zomwe zimalola kuti zigwiritsidwe ntchito ngati chonyowetsa komanso kufalitsa.
4. Kukhazikika kwabwino kwa kutentha: HPMC ndi yokhazikika pa kutentha kwakukulu ndipo ingagwiritsidwe ntchito pazinthu zomwe zimafuna ntchitoyi.
5. Kumamatira kwabwino kumadera osiyanasiyana: HPMC imatha kulumikizana ndi malo ambiri, ndikupangitsa kuti ikhale yothandiza popanga zomatira ndi zokutira.
Kugwiritsa ntchito HPMC m'mafakitale osiyanasiyana:
1. Mankhwala: HPMC imagwiritsidwa ntchito kwambiri pokonzekera mankhwala monga binder, disintegrant, ndi viscosity regulator. Amapezeka m'mapiritsi, makapisozi ndi ma formulations amadzimadzi.
2. Chakudya: HPMC imagwiritsidwa ntchito ngati thickener, stabilizer ndi emulsifier muzakudya. Itha kugwiritsidwa ntchito pazinthu monga ayisikilimu, yogurt ndi mavalidwe a saladi.
3. Zodzoladzola: HPMC imagwiritsidwa ntchito kwambiri muzodzoladzola monga thickener, emulsifier, ndi kupanga mafilimu. Itha kugwiritsidwa ntchito pazinthu monga zonona, lotions ndi shampoos.
4. Zomangamanga: HPMC ndi chinthu chofunika kwambiri pa zinthu zambiri zomangira monga zomatira matailosi, pulasitala wopangidwa ndi simenti ndi matope. Imagwira ntchito ngati chosungira madzi, imathandizira kugwira ntchito bwino, komanso imathandizira kumamatira komanso kuwongolera bwino.
Chiyerekezo chamakampani a HPMC:
1. Kusunga madzi: Mlingo wosungira madzi wa HPMC ndi gawo lofunikira lomwe limatsimikizira kuti limagwira ntchito ngati thickener ndi zomatira. Malowa ali ndi mbiri yamakampani a 80-100%.
2. Viscosity: Viscosity ndi gawo lofunikira pakusankha HPMC pazogwiritsa ntchito zosiyanasiyana. Mawonekedwe amakampani a viscosity amachokera ku 5,000 mpaka 150,000 mPa.s.
3. Zomwe zili mugulu la methoxyl: Gulu la methoxyl la HPMC limakhudza kusungunuka kwake, kukhuthala kwake komanso kupezeka kwake. Chiyerekezo chamakampani okhudzana ndi methoxy chili pakati pa 19% ndi 30%.
4. Hydroxypropyl content: Zomwe zili mu hydroxypropyl zimakhudza kusungunuka ndi kukhuthala kwa HPMC. Chiyerekezo chamakampani okhudzana ndi hydroxypropyl chili pakati pa 4% ndi 12%.
HPMC ndi polima wosunthika wokhala ndi ntchito zambiri zamafakitale. Makhalidwe ake apadera amapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pamankhwala, chakudya, zodzoladzola ndi zomangamanga. Kuwerengera kwamakampani kumagawo osiyanasiyana kumathandiza pakusankha giredi yoyenera ya HPMC kuti mugwiritse ntchito.
