Hydroxypropylmethylcellulose (HPMC) is cellulose ether inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana nekuda kwekusiyana kwayo uye kuita kwakasiyana-siyana.Iyo isiri-chepfu, inonyungudika mumvura polymer inonyungudika mumvura inotonhora uye inopisa.Icho chinhu chakakosha mbishi chave chichishandiswa se thickener, binder, stabilizer, emulsifier, uye firimu rekare mune akasiyana maapplication akadai seindasitiri yechikafu, mishonga, kuvaka, uye cosmetics.
Chimwe chezvinhu zvakakosha zveHPMC ndeye yakakura viscosity renji.Iyo viscosity yeHPMC inotsamira pane akati wandei zvinhu zvakaita sedhigirii rekutsiva, huremu hwemamorekuru uye kusungwa.Naizvozvo, HPMC inogona kushandiswa mune dzakasiyana siyana maapplication anoda akasiyana viscosity mazinga.Semuyenzaniso, high-viscosity HPMC inowanzoshandiswa seyakakora uye inodzikamisa mukudya, nepo yakaderera-viscosity HPMC inoshandiswa muindasitiri yemishonga sebhainda uye piritsi yekupfeka.
HPMC kuchena zvakare chinhu chakakosha.Iyo inowanzouya mumakiredhi akasiyana ehutsanana kubva pa99% kusvika 99.9%.Iwo akanyanya kuchena mamakisi anowanzo kufarirwa neindasitiri yemishonga, iyo ine mitemo yakasimba pamhando yezvigadzirwa.Kuchena kwepamusoro kweHPMC kunobatsira kuve nechokwadi chemhando yepamusoro yechigadzirwa chekupedzisira.Iyo nhanho yekuchena inokanganisawo HPMC zvivakwa senge viscosity, solubility, uye gelation.Kazhinji, mazinga akakwirira ekuchena anovandudza maitiro ekushanda.
Kuwedzera kune viscosity uye kuchena, pane zvimwe zvakakosha zvekufunga nezvazvo paunosarudza iyo chaiyo HPMC kune imwe application.Izvi zvinosanganisira saizi yechidimbu, nzvimbo yepasi, hunyoro hwemukati uye dhigirii rekutsiva.Particle size uye nzvimbo yeHPMC inogona kukanganisa kunyungudika kwayo, ukuwo hunyoro huchikanganisa kugadzikana kwayo uye hupenyu hwesherufu.Izvo zvakakosha kuti usarudze dhigirii chaiyo yekutsiva, kureva chikamu chehukama chehydroxypropyl uye methyl zvinotsiva muHPMC molecule.Madhigirii epamusoro ekutsiva anogona kutungamira mukuwedzera kunyungudika kwemvura uye yakagadziridzwa viscosity, nepo yakaderera madhigirii ekutsiva anogona kutungamira kune yakawedzera firimu-kuumba zvivakwa.
food industry
Muindasitiri yechikafu, HPMC inowanzoshandiswa seyakakora, emulsifier uye inodzikamisa mumhando dzakasiyana dzezvigadzirwa senge sosi, soups, madhirezi, zvigadzirwa zvemukaka uye zvakabikwa.HPMC inosimudzira magadzirirwo echikafu nekupa yakatsetseka, ine cream uye yakafanana kuenderana.Inobatsirawo kudzivirira zvinhu kubva pakuparadzana, nokudaro kuwedzera hupenyu hwesherufu yezvokudya.
Chimwe chezvinhu zvakakosha zveHPMC muindasitiri yechikafu kugona kwayo kuchengetedza chigadzirwa viscosity pane tembiricha yepamusoro, senge panguva yekubika uye pasteurization.Kugadzikana kwepamusoro-tembiricha yeHPMC inobvumira kuti ishandiswe mukupisa-kupisa kwechikafu senge zvigadzirwa zvemumagaba kana sherufu-yakagadzika.
Pharmaceutical industry
Muindasitiri yemishonga, HPMC inowanzoshandiswa sebinder, disintegrant, tablet coating agent, controlled release agent, etc. mumishonga yakasiyana-siyana yemishonga.HPMC inofarirwa pane zvimwe zvinonamira nekuti haina chepfu uye inonyungudika mumvura inopisa uye inotonhora.Iko kukwanisa kunyungudika mumvura inopisa uye inotonhora inonyanya kukosha kune granulation yakanyorova, nzira yakajairika yekugadzira mapiritsi.
HPMC inoshandiswawo se disintegrant yemapiritsi.Inobatsira kuputsa mapiritsi kuita zvidimbu zviduku, izvo zvinovandudza chiyero apo mushonga unopinda mumuviri.Pamusoro pezvo, HPMC inowanzo shandiswa sechinhu chinoputira nekuda kweiyo firimu-kugadzira zvimiro.Inodzivirira piritsi kubva kune zvakatipoteredza zvinhu, nokudaro kuwedzera hupenyu hwesherufu.
simudza
Muindasitiri yekuvaka, HPMC inoshandiswa kuvandudza kushanda uye kuita kwezvakasiyana zvigadzirwa simende senge madhaka, grouts uye plasters.HPMC inoita seyakakora, inonatsiridza kunamatira, uye inopa kuchengetedza kwemvura zvivakwa kumusanganiswa.Kugona kweHPMC kugadzira firimu rekudzivirira kunobatsirawo kudzivirira mvura kuti isapinda mukati mesimende matrix, ichivandudza kusimba.Iyo viscosity yeHPMC inoita basa rakakosha mukushanda kwemusanganiswa.Naizvozvo, zvichienderana nekushandiswa, akasiyana viscosity mamakisi eHPMC anoshandiswa.
cosmetic
Muindasitiri yezvizorwa, HPMC inoshandiswa seyakakora, stabilizer, uye firimu rekare mune zvakasiyana zvigadzirwa senge shampoos, maconditioner, uye lotions.HPMC inokwidziridza magadzirirwo uye kuenderana kwezvizoro, ichipa yakatsetseka, yakapfava kupera.Iyo inovandudzawo kugadzikana kwechigadzirwa uye hupenyu hwesherufu nekudzivirira kupatsanurwa kwezvinhu.Pamusoro pezvo, iyo firimu-inogadzira zvimiro zveHPMC inopa chinodzivirira chinobatsira kuchengetedza unyoro, nekudaro kudzivirira kuoma.
mukupedzisa
Hydroxypropyl methylcellulose ine huwandu hwakasiyana hweviscosity uye kuchena zvinodiwa.Iyo yakawanda inoshanda raw material inoshandiswa zvakanyanya mumaindasitiri akasiyana sechikafu, mushonga, kuvaka, uye zvizorwa.Iyo yakafara viscosity renji inobvumira HPMC kuti ishandiswe mune akasiyana maapplication anoda akasiyana viscosity mazinga.Kuchena kwepamusoro kwakakosha kune indasitiri yemishonga, iyo ine mitemo yakasimba pamhando yezvigadzirwa.HPMC yakakosha kumabasa ezvigadzirwa zvakawanda, saka kufunga nezve chaiyo viscosity uye kuchena nhanho kwakakosha.
