Hydroxypropylmethylcellulose (HPMC) is nonionic cellulose ether ine zvivakwa zvinosanganisira kuchengetedza mvura, kugadzira firimu uye kukora. Inowanzoshandiswa muhupfu mumhando dzakasiyana-siyana dzakadai sekuvaka, mishonga uye chikafu.
Muindasitiri yekuvaka, HPMC inowanzoshandiswa seyakakora, bhainda uye inochengeta mvura musimende, gypsum nedhaka. Kana yakashandiswa seyakakora, inopa kushanda kuri nani uye inowedzera kuenderana kwezvinhu. Uye zvakare, inokwidziridza zvivakwa zvakaita senge crack resistance, adhesion and durability ye simenti, gypsum uye dhaka. Huwandu hushoma hweHPMC hunogona kuvandudza zvakanyanya kunaka kwezvinhu zvekuvaka, zvichiita kuti ive yakakodzera kune akasiyana mafomu.
Muindasitiri yemishonga, HPMC inowanzoshandiswa sebhainda, disintegrant uye inosimudzira-kuburitswa mumapiritsi, capsules, uye granules. Sebhainda, HPMC inowedzera simba rehwendefa uye inodzivirira kubva pakutyoka panguva yekubata. Senge disintegrant, HPMC inobatsira piritsi kunyungudika nekukurumidza mudumbu remukati. Iyo inoshandiswawo seyakadzora-kuburitsa mumiriri, ichipa nguva yakareba yekuburitswa kwezvinodhaka. Zvinhu izvi zvinoita kuti HPMC ive chinhu chakasiyana-siyana cheindasitiri yemishonga, ichibatsira mukuvandudza maumbirwo matsva, kuvandudza kutevedza kwevarwere uye kuwedzera kushanda kwemishonga.
Muindasitiri yechikafu, HPMC inowanzoshandiswa seyakakora, stabilizer uye emulsifier muzvigadzirwa zvakasiyana seaizikirimu, yogati uye sosi. Inopa chimiro chakatsetseka, inovandudza muromo, uye inodzivirira zvigadzirwa kubva pakuparadzanisa kana kugadzirisa. Pamusoro pezvo, inowedzera hupenyu hwesherufu yezvigadzirwa uye inoderedza kudiwa kwekuchengetedza. HPMC inowanzo shandiswa mune yakaderera-calori kana yakaderera-mafuta chikafu nekuti inogona kutevedzera magadzirirwo emafuta nekupa krimu manyoro pasina kuwedzera mamwe macalorie.
Kunze kwebasa rayo guru, HPMC ine zvimwe zvakanakira mumaindasitiri akasiyana. Yakachengeteka kunwiwa nevanhu, inonyungudika zviri nyore mumvura, uye haina kunaka kana kunhuwa. Iyo zvakare ine biodegradable uye ine hushamwari kwezvakatipoteredza, ichiita iyo inogoneka sarudzo kune akawanda maapplication. Iyo yakaderera muchetura uye hypoallergenicity yeHPMC inoita kuti ive chinhu chakachengeteka mumhando dzakasiyana dzezvigadzirwa, zvinosanganisira zvekuzora, zvekugezesa uye pendi.
Mukupedzisa, HPMC sechipo mufomu yehupfu yakakosha kwakakosha mumaindasitiri akati wandei akadai sekuvaka, mishonga uye chikafu. Yayo yakawanda inoshanda zvinhu inoita kuti ive chinhu chakakosha mukugadzirwa kwechigadzirwa chitsva uye kugadzirwa, kuvandudza kunaka, kuwirirana uye kushanda kwechigadzirwa chekupedzisira. Kuchengetedzeka kwayo, kuenderera mberi uye biodegradability inoita kuti ive chinhu chakakodzera kune akasiyana maapplication, zvichibatsira mukusimudzira zvigadzirwa zvemazuva ano.
