Hydroxypropylmethylcellulose (HPMC) ipolymer inoshandiswa zvakanyanya mumaindasitiri akasiyana. Iyo isiri-ionic cellulose ether, inonyungudika nemvura, isina chepfu uye isingatsamwisi. HPMC inowanzoshandiswa semukobvu, bhainda uye emulsifier mune zvakawanda zvekudya, mishonga uye zvigadzirwa zvekuchengeta munhu.
Chimwe chezvinhu zvakakosha zveHPMC ndeye huremu hwayo hwema molecular, iyo inokanganisa viscosity yayo. Viscosity chiyero chekuramba kwemvura kuyerera. Iyo yakakwirira viscosity, iyo inowedzera mvura. Molecular huremu chiyero chekukura kwema molecular, iyo yakanangana neiyo viscosity yeHPMC.
HPMC inowanikwa mumagiredhi akasiyana zvichienderana nehuremu hwayo. Iyo viscosity yeHPMC inowedzera nehuremu hwemamorekuru. Iyo viscosity yeHPMC zvakare inopesvedzerwa nedhigirii rekutsiva (DS), inova nhamba yehydroxypropyl uye methyl mapoka akasungirirwa kumusana we cellulose. Iyo yakakwira iyo DS, ndiyo yakakwirira huremu hwemamorekuru uye viscosity yeHPMC.
Iyo viscosity yeHPMC inobatwawo neiyo polymer concentration mune mhinduro. Pakudzika kwakadzika, iyo polymer cheni inoparadzirwa uye mhinduro viscosity yakaderera. Sezvo huwandu hunowedzera, cheni dzepolymer dzinotanga kupindirana uye kupindirana, zvichikonzera kuwedzera kwe viscosity. Iyo yekumisikidza iyo polymer cheni inotanga kupindirana inonzi iyo overlap concentration.
Huremu hwemamorekuru uye viscosity yeHPMC yakakosha paramita mune zvakawanda zvigadzirwa zvekugadzira. Muindasitiri yechikafu, HPMC inoshandiswa seyakakora yemasosi, mapfekero uye zvinhu zvakabikwa. Iyo yakakodzera mamorekuru huremu uye viscosity yeHPMC inova nechokwadi cheinodiwa manyorerwo uye muromo wekunzwa kwechigadzirwa chekupedzisira.
Muindasitiri yemishonga, HPMC inoshandiswa sebhainda remapiritsi nemakapisi. Huremu hwemamorekuru uye viscosity yeHPMC inosarudza kusimba kwehwendefa uye kugona kwayo kunyungudika mudumbu remukati.
Muindasitiri yekuchengeta munhu, HPMC inoshandiswa seyakakora uye emulsifier mumashampoos, lotions nemafuta. Iyo yakakodzera mamorekuru huremu uye viscosity yeHPMC inova nechokwadi chekuenderana uye kugadzikana kwechigadzirwa.
Kupfupisa, huremu hwemamorekuru uye viscosity yeHPMC yakakosha paramita inokanganisa mashandiro ayo mumaindasitiri akasiyana. Kunzwisisa hukama pakati pemaparamita aya kwakakosha pakugadzira zvigadzirwa zvinosangana nezvinodiwa. HPMC inogoneka uye yakakosha polymer inobatsira kuvandudza kunaka uye kuita kwezvigadzirwa zvakawanda.
