Hydroxylopenyl cellulose (HPMC) i polymer yekugadzira iyo inoshandiswa zvakanyanya mumhando dzakasiyana siyana semishonga, chikafu, zvivakwa uye zvekuzora.Inobva ku cellulose uye inoumba glue coagulant pane iyo hydrophilic.Iyo yakachena fomu yeHPMC ichena isina kunaka poda inonyungudutswa mumvura kuti igadzire inoonekera mucus mhinduro.
Hupombwe hweHPMC inzira yekuwedzera kana kusanganisa zvinhu zvakachena kune zvimwe zvinhu kuti zvishandure maitiro ayo kana kuderedza mutengo wekugadzira.Iyo doping muHPMC inogona kushandura iyo yemuviri, kemikari uye michina zvimiro zveHPMC.HPMC inoshandisa akati wandei akajairika doping agents, anosanganisira starch, mapuroteni emuzambiringa, cellulose, sucrose, glucose, carboxymethyl cellulose sodium (CMC) uye polyethylene ethylene (PEG).Kuwedzerwa kweava vakuru kunokuvadza kunaka, kuchengeteka uye kushanda kweHPMC.
Pane misiyano yakati wandei pakati peyakachena HPMC nehupombwe cellulose:
1. Kuchena: Musiyano mukuru pakati peHPMC yakachena nehupombwe cellulose ndiko kuchena kwavo.Yakachena HPMC chinhu chimwe chete chisina tsvina kana zvinowedzerwa.Ukuwo, hupombwe cellulose ine zvimwe zvinhu, zvingava zvimwe zvinhu zvinokanganisa nemaune kana kusaziva kunaka kwavo uye maitiro.
2. Mamiriro emuviri: Yakachena HPMC imhando yehupfu huchena, husina kunaka, hunonyunguduka mumvura kuti hugadzire mhinduro yakajeka ye viscous.Iyo hupombwe HPMC inogona kunge iine hunhu hwakasiyana hwemuviri, zvichienderana nerudzi uye uwandu hwekuwedzera kwehupombwe mumiriri.Kupinda kunogona kukanganisa solubility, viscosity uye ruvara rwechinhu.
3. Kemikari maitiro: Yakachena HPMC i polymer yakachena kwazvo ine maitiro emakemikari anowirirana.Kubvuma kune zvimwe zvinhu kunogona kuchinja kemikari maitiro eHPMC, ayo anokanganisa mabasa ayo uye kuchengeteka.
4. Kuchengeteka: Kushandiswa kwehupombwe cellulose kunogona kukuvadza hutano nekuti hupombwe uhwu hunogona kunge huine chepfu kana chinokuvadza.Iyo hupombwe HPMC inogona zvakare kudyidzana nezvimwe zvinhu nenzira isingafungidzike, izvo zvinokonzeresa matambudziko makuru ehutano.
5. Mutengo: Yakagadziridzwa cellulose yakachipa kupfuura yakachena HPMC, nekuti kuwedzera kweiyo doping agents kunoderedza mutengo wekugadzira.Nekudaro, kushandiswa kwehupombwe HPMC mukugadzira zvinodhaka kana zvimwe zvigadzirwa zvinogona kukanganisa kunaka uye kushanda kwechigadzirwa.
Zvese mune zvese, yakachena HPMC ikanyanya kuchena uye yakachengeteka polima, ine inopindirana makemikari uye emuviri maitiro.Kusangana nezvimwe zvinhu zvinogona kushandura hunhu hweHPMC, nekudaro kukuvadza kunaka uye kuchengetedzeka kwechigadzirwa.Naizvozvo, yakachena HPMC inofanirwa kushandiswa mukugadzira zvinodhaka, chikafu, zvivakwa uye zvimwe zvigadzirwa.
