Hydroxypropylmethylcylosellose (HPMC) ndeye cellulose ether inoshandiswa zvakanyanya mune dzakasiyana-siyana maindasitiri nekuda kwezvivakwa zvaro zvakasiyana uye zvinoshamisa. Icho chisiri chepfu, chine mvura-yemvura polymer iyo inonaka mumvura inotonhora uye inopisa. Icho chinhu chakakosha chitsva chakashandiswa sedhizai, binder, stabilizer, emulsifier, uye yefirimu yaimbova mumanyorero akasiyana-siyana seindasitiri yechikafu, mishonga, kuvaka, uye cosmetics.
Imwe yeiyo yakakosha zvivakwa zveHPMC ndeye Yahwe Yake viscossity range. Iyo viscosity yeHPMC inoenderana nezvikamu zvinoverengeka zvakadai sedanho rekutsiva, zvinyoro-nyoro uye kusvinura. Naizvozvo, HPMC inogona kushandiswa mune dzakasiyana siyana dzekushandisa dzinoda huwandu hwakasiyana viscosity. Semuenzaniso, yepamusoro-viscosity HPMC inowanzo shandiswa seyakavharwa uye stabilizer muchikafu, nepo low-vcosity hpmc inoshandiswa muindasitiri yemishonga seyekuchengetera uye piritsi yekuvhara.
Hpmc kuchena zvakare chinhu chakakosha. Izvo zvinowanzouya mumakadhi akasiyana-siyana ekuchenesa kubva 99% kusvika 99.9%. Iyo yepamusoro yepamusoro mamakisi anowanzo sarudza neyechiindasitiri yemishonga, iyo ine mitemo yakasimba pamhando yezvinhu zvisina kugadzirwa. Iko kuchena kwepamusoro kweHPMC kunobatsira kuve nechokwadi chakanakisa kunaka kwechigadzirwa chekupedzisira. Iyo nhanho yekuchena zvakare inokanganisa hpmc zvivakwa zvakadai se viscosity, solubility, uye glation. Muzhinji, yakanyanya kuchena mazinga anovandudza maitiro ekuita.
Kuwedzera kune viscosity uye kuchena, pane zvimwe zvinhu zvakakosha zvekufunga kana uchisarudza iyo hpmc yakakodzera yeimwe application. Izvi zvinosanganisira size size, nzvimbo yemusoro, zvinyoro-nyoro uye degree rekutsiva. Chikamu chevhu uye nzvimbo yekumusoro yeHPMC inogona kukanganisa iyo solubility, nepo kunyorova kwemukati kunokanganisa kugadzikana kwayo uye mararamiro asherufu. Izvo zvakakosha kusarudza iyo chaiyo degree rekutsiva, kureva kuenderana kwehydroxypruppropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropropyl uye methyl siki mune iyo hpmc molecule. Dhigirii dzakakwirira dzekutsiva dzinogona kutungamira kune kuwedzera mvura solubility uye yakagadziridzwa viscosity, nepo madhigirii akadzika ekutsiva anogona kutungamira kuisimudzira firimu remafirimu.
Indasitiri yechikafu
Muindasitiri yekudya, HPMC inowanzo shandiswa seyekupedzisira, emulsifieri uye stabilizer mune zvigadzirwa zvakasiyana senge sosi, masaga, zvigadzirwa, zvigadzirwa zvemukaka uye zvinhu zvakabikwa. HPMC inosimudzira iyo yekugadzira yezvikafu nekupa yakatsiga, kirimu uye yunifomu yekuenderana. Izvo zvakare zvinobatsira kudzivirira zvivakwa kuti zviparadzanise, nekudaro tichiwedzera hupenyu hwesherufu hwekudya.
Chimwe chezvivakwa zvakakosha zveHPMC muindasitiri yekudya ndiko kugona kwayo kuchengetedza viscosity kune yakakwirira tembiricha, sekubika nekubika. Iyo yakakwira-tembiricha kugadzikana kweHPMC inobvumira kuti ishandiswe mune yakanyanya-tembiricha yezvikafu zvakakosheswa kana zvigadzirwa zvehembe.
Indasitiri yeMishonga
Muindasitiri yemishonga, HPMC inowanzo shandiswa seyekubhuka, kuparadzaniswa, piritsi yekubatanidza mumiririri, etcompled kuburitsa, etc. mune dzakasiyana siyana gadziriso. HPMC inosarudzwa pamusoro pezvimwe zvinonamatira nekuti haina chepfu uye inokanganisa mumvura inopisa uye inotonhora. Iko kugona kwekunyungudika mumvura inopisa uye inotonhora kunonyanya kubatsira pakurudyi, nzira yakajairika yekugadzira mahwendefa.
HPMC inoshandiswawo sekuparadzaniswa kwemahwendefa. Iyo inobatsira kuputsa mapiritsi muzvimedu zvidiki, izvo zvinovandudza chiyero icho mushonga unobatwa mumuviri. Mukuwedzera, HPMC inowanzoshandiswa seyekubatanidza mumiririri nekuda kweiyo firimu-fomu yekugadzira. Iyo inodzivirira piritsi kubva pazvinhu zvemamiriro ekunze, nekudaro inowedzera hupenyu hweshere.
simudza
Muindasitiri yekuvaka, HPMC inoshandiswa kuvandudza basa rekushanda uye kuita kwezvigadzirwa zvakasiyana siyana zvemweya semota, graster uye plasters. HPMC zviito seanotenda, inovandudza kudiwa, uye inopa kudzokorora kwemvura kune iyo musanganiswa. Kugona kwaHPMC kuumba iyo firimu yekudzivirira inobatsira zvakare kudzivirira mvura kubva mukupinza mumisangano yemasangano, ichivandudza kusimba. Iyo viscosity yeHPMC inoita basa rakakosha mukushanda kwemusanganiswa. Naizvozvo, zvichienderana nekushandisa, akasiyana viscosity mamakisi eHPMC anoshandiswa.
cosmetic
MuCosmetic indasitiri, HPMC inoshandiswa seanoshandiswa, STabilizer, uye yefirimu yaimbova muzvigadzirwa zvakasiyana-siyana senge shampoos, magetsi, uye marara. HPMC inosimudzira iyo yekunyora uye kuenderana kwecosmetics, kupa iyo yakatsiga, yekupedzisa kupedzisa. Iyo inovandudzawo kugadzikana kwechigadzirwa uye mararamiro asherufu nekudzivirira kupatsanurana kwezvinhu zvirimo. Pamusoro pezvo, iyo firimu-yekuumba midziyo yeHPMC inopa chipinganidzo chekudzivirira chinobatsira kuchengetedza kunyorova, nekudaro kudzivirira kuoma.
mumhedziso
Hydroxyprupylmyl methylcellose ine huwandu hwakawanda hwe viscosity uye zvekuchenesa zvinodiwa. Icho chinhu chaunga chomuimayifiketi chakabiwa chinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana senge chikafu, mushonga, kuvaka, uye cosmetics. Iyo yakafara viscosity renji inobvumira HPMC kuti ishandiswe mune dzakasiyana siyana dzekushandisa dzinoda huwandu hwakasiyana viscosity. Yakakwira mazinga ekuchena akanyanya kudenha kune iyo mishonga indasitiri, iyo ine mitemo yakasimba pamhando yezvinhu zvisina kugadzirwa. HPMC inokoshesa kushanda kwezvigadzirwa zvakawanda, saka kufunga kweiyo chaiyo viscosity uye yakacheneswa chikamu chakakosha.
