Hydroxypropylmethylcellulose (HPMC) i polymer inoshanda zvakasiyana-siyana ine huwandu hwakawanda hwekushandisa mumaindasitiri akasiyana.Imwe yemaindasitiri ayo HPMC inoita basa rakakosha iindasitiri yependi uye yekupfeka.Nekuda kwezvimiro zvayo zvakasiyana, HPMC inoshandiswa mupendi uye machira sechinhu chakakosha mukugadzira zvigadzirwa izvi.
HPMC i polymer inonyungudika mumvura inotorwa kubva ku cellulose ethers.Iine zvinhu zvakasiyana-siyana zvakadai sekukwirira kwepamusoro, kubatana, kunamatira, kuderera kwedota, kugadzira firimu, uye kuchengetedza mvura.Izvi zvinhu zvinoita kuti HPMC ive chinhu chakanakira mukugadzirwa kwependi nekugadzira zvigadzirwa.
Kushandiswa kweHPMC muindasitiri yependi uye yekupotera kunounza akawanda mabhenefiti kune vanogadzira, vanogovanisa uye vashandisi vekupedzisira.Zvimwe zvezvibatsiro izvi zvinokurukurwa pasi apa:
1. Mukobvu
Imwe yemabhenefiti makuru ekushandisa HPMC mupendi uye coating magadzirirwo iko kushandiswa kwayo semukobvu.HPMC ine yakanakisa thickening zvivakwa uye inowanzo shandiswa kuwedzera viscosity yejasi.Iyi pfuma yakakosha pakugadzira machira ane yakatsetseka, yunifomu uye iri nyore kushandisa.
Kukora kwepende kunonyanya kukosha kune pendi uye machira anoshandiswa nebhurashi kana roller.HPMC-yakavakirwa maumbirwo inopa mabhenefiti ekudzivirira kubva kudonhedza pendi, kumhanya uye kupuruzira.Naizvozvo, HPMC inogona kubatsira vagadziri kugadzira mapendi uye pendi zviri nyore kushandisa uye kubata, zvichiita kuti zvizivikanwe nevashandisi.
2. Kuchengeta mvura
HPMC inonzi hydrophilic polymer ine simba rekuchengetedza mvura.Iine zvinhu zvakanakisa zvekuchengetedza mvura, iyo inobatsira zvikuru mukugadzira pendi uye machira.Kuchengetwa kwemvura kunowedzera kufanana kwefirimu uye kunopa nani kupararira kwemavara.Inobatsirawo kuwedzera hupenyu hwesherufu yepende.
Uyezve, kuchengetwa kwemvura ndeimwe yeanonyanya kukosha ma parameter ekuputira kunaka uye kuita.Pendi inoda kuramba ichishanda kwenguva yakareba uye HPMC inova nechokwadi chekuti pendi haina kuoma nekukasira.
3. Kubatana uye Kunamatira
HPMC ine yakanakisa yekubatanidza uye yekubatanidza zvivakwa, zvichiita kuti ive chinhu chakakosha mupendi uye machira.Iyo polysaccharide moiety muHPMC ine basa rekusungirira uye kunamatira zvimiro zvepolymer.
Iwo anonamira zvimiro zveHPMC anobatsira kubata pigments nemafiller pamwechete, zvichikonzera ruvara rweunifomu mufirimu repende.HPMC inova nechokwadi chekupararira kwakanaka kwemavara uye mafirita mupende, zvichikonzera kupera kwakatsetseka, kwakasimba.
Kune rumwe rutivi, kusungirirwa kweHPMC kunobatsira kunamatira kwefirimu yepende kune substrate, zvichiita kuti pendi igare yakasimba uye inogara kwenguva refu.
4. Kukwanisa kugadzira firimu
HPMC inoita seyaimbova firimu kana ichigadzira pendi uye machira.Inobatsira kugadzira firimu rinoenderera rinochengetedza nzvimbo kubva kune zvakatipoteredza zvinhu zvakadai sezuva, mvura uye humidity.Kuumbwa kwefirimu iyi kunodzivirira substrate kubva kune abrasion, corrosion uye kumwe kukanganisa.
Pamusoro pezvo, HPMC-yakavakirwa pendi mafirimu akagadzikana mumakemikari uye anoratidza yakanakisa stain kuramba uye kusimba, zvichiita kuti ive yakanakira zvikamu zvependi yemba.
Iko kushandiswa kwehydroxypropyl methylcellulose mupendi uye maumbirwo ekuputira kunopa akawanda mabhenefiti kune vanogadzira, vanogovera uye vashandisi vekupedzisira.HPMC-yakavakirwa pendi uye mapendi anofarirwa nevatengi mukukora kwazvo, kuchengetedza mvura, kusungirira, kunamatira uye kugadzira firimu.Inowedzera kunaka uye kushanda kwepende uye zvigadzirwa zvekupfekedza, zvichipa kukosha kuri nani kune vashandisi.Mune ramangwana, kuiswa kweHPMC mukugadzirwa kwependi uye machira kunokurudzirwa zvakasimba.
