suma:
Hydroxypropylmethylcellulose (HPMC) musanganiswa unoshanda unoshandiswa zvakanyanya mumaindasitiri akati wandei nekuda kweakasiyana anobatsira zvinhu.Inobva ku cellulose, inowanikwa nekemikari inoshandura cellulose ine propylene oxide uye methyl chloride.HPMC inoshandiswa zvakanyanya mumaindasitiri emishonga, chikafu, kuvaka uye cosmetic nekuda kwekunaka kwayo kuchengetedza mvura.Iri bepa rinopa ongororo yakadzama yemaitiro ekuchengetedza mvura kweHPMC.
Kuchengeta mvura kweHPMC:
Iyo yekuchengeta mvura zvivakwa zveHPMC ndechimwe chezvikonzero zvakakosha zvekushandiswa kwayo kwakapararira mumaindasitiri akati wandei.HPMC ine yakakwirira yekuchengeta mvura simba nekuda kweiyo hydrophilic hunhu.Inotora mvura uye inozvimba kusvika kakawanda kukura kwayo kwepakutanga, zvichiita kuti ive yakanaka kuchengetedza mvura.Kuchengeta mvura kweHPMC kunotsamira pane zvakati wandei zvakaita sedhigirii rekutsinhanisa, viscosity yemushonga weHPMC, uye rudzi rwekunyungudutsa kunoshandiswa.
Degree rekutsiva:
Iyo dhigirii yekutsiva (DS) yeHPMC chinhu chakakosha chinokanganisa mashandiro ayo ekuchengetedza mvura.Iyo DS yeHPMC inoreva huwandu hwemapoka ehydroxyl anotsiviwa nehydroxypropyl uye methyl mapoka mune cellulose molecule.HPMC ine dhigirii repamusoro rekutsiva ine simba rekuchengetedza mvura yepamusoro pane HPMC ine dhigirii yakaderera yekutsiva.Iyo yepamusoro DS yeHPMC inowedzera hydrophilicity yemorekuru, zvichikonzera kuchengetwa kwemvura kuri nani.
Viscosity yeHPMC mhinduro:
Iyo viscosity yeHPMC mhinduro ndechimwe chinhu chinokanganisa mashandiro ekuchengetedza mvura kweHPMC.Iyo viscosity yeHPMC mhinduro inowedzera nekuwedzera kweHPMC kusungwa mune solvent.Nekuda kwekuvapo kweakawanda HPMC mamorekuru mune solvent, iyo yakakwirira viscosity yeHPMC mhinduro, zviri nani kuchengetedza mvura.High viscosity HPMC mhinduro dzinogadzira gel-senge chimiro chinoteya mamorekuru emvura uye anoadzivirira kubva pakubuda.
Solvent Type inoshandiswa:
Mhando yekunyungudutsa inoshandiswa kugadzira iyo HPMC mhinduro inogonawo kukanganisa maitiro ayo ekuchengetedza mvura.HPMC inonyungudika mumvura uye akasiyana organic solvents, senge doro, esters, uye ketoni.Iyo solvent inoshandiswa kugadzira iyo HPMC mhinduro inogona kukanganisa kuzvimba maitiro emorekuru.HPMC inozvimba zvakanyanya mumvura uye inotora mvura yakawanda kupfuura HPMC mune organic solvents.Kuenzaniswa ne organic solvent mhinduro, HPMC ine zvirinani kuchengetedza mvura mumhinduro dzine aqueous.
Kushandiswa kweHPMC mumaindasitiri akasiyana siyana:
Nekuda kwekunaka kwayo kwekuchengetedza mvura zvivakwa, HPMC inoshandiswa zvakanyanya mumaindasitiri akati wandei akadai semishonga, chikafu, kuvaka uye zvizorwa.
Pharmaceutical industry:
Muindasitiri yemishonga, HPMC inowanzoshandiswa sebhainda, disintegrant uye coating agent.Inoshandiswa sebhainda mukugadzirira piritsi kuti ibate zvinhu pamwe chete.Senge disintegrant, HPMC inobatsira kuputsa piritsi racho kuita zvidimbu zvidiki mudumbu, izvo zvinovandudza kutora kwezvinodhaka.HPMC inoshandiswa seyakaputira kudzivirira mushonga kubva kune unyoro uye kudzora kuburitswa kwezvinodhaka.
indasitiri yezvekudya:
Muindasitiri yechikafu, HPMC inoshandiswa semulsifier, stabilizer uye thickener.Inoshandiswa emulsify mafuta uye mvura-based zvinwiwa, kudzikamisa chikafu, uye kukora sosi nemagravi.HPMC inoshandiswawo sekuzadza kuwedzera huwandu kune chikafu.
Indasitiri yekuvaka:
Muindasitiri yekuvaka, HPMC inowanzo shandiswa mune simende-yakavakirwa zvinhu zvakaita sedhaka nekongiri.Inoshandiswa sechinhu chekuchengetedza mvura kudzivirira kubuda kwemvura mumusanganiswa wesamende.HPMC inogonawo kuvandudza kushanda kwemusanganiswa wesimende uye kuderedza kuputika kwezvinhu.
Cosmetics industry:
Muindasitiri yezvizorwa, HPMC inoshandiswa seyakakora, emulsifier uye inogadzirisa agent.Inoshandiswa kukora lotions uye makirimu, emulsify mafuta uye mvura-based ingredients, uye mamiriro bvudzi.
mukupedzisa:
Mukupedzisa, nzvimbo yekuchengetedza mvura yeHPMC ndeimwe yeayo akakosha uye anobatsira zvivakwa.HPMC ine simba rekuchengetedza mvura yakakwira nekuda kwechimiro chayo chehydrophilic, ichiigonesa kutora uye kuchengetedza mvura uye kuidzivirira kubva pakubuda.Iyo dhigirii yekutsiva, mhinduro viscosity uye rudzi rwesolvent inoshandiswa zvinhu zvakakosha zvinokanganisa kuchengetedzwa kwemvura kweHPMC.HPMC inoshandiswa zvakanyanya mumaindasitiri akasiyana akadai semishonga, chikafu, kuvaka uye zvizorwa nekuda kwekunaka kwayo kwekuchengetedza mvura.
