Methylcellulose (MC) ikemikari yakagadziridzwa cellulose, mvura-inonyungudika polima inowanikwa nechikamu methylation ye cellulose. Nekuda kweiyo yakasarudzika physicochemical zvimiro uye biocompatibility, methylcellulose inoshandiswa zvakanyanya mukudya, mushonga, zvekuvaka, zvizorwa uye mamwe minda.
1. Kunyungudika kwemvura uye kukwanisa kugadzira gel
Methylcellulose ine mvura yakanaka yekunyungudika uye inogona kugadzira yakajeka colloidal mhinduro mumvura inotonhora. Kana tembiricha ichikwira, mhinduro iyi ichaita thermal gelation kuti iite gel yakagadzikana. Ichi chivakwa chinoita kuti methylcellulose ishandiswe zvakanyanya muaizikirimu, kirimu, jelly uye zvimwe zvigadzirwa seyakakora, stabilizer uye emulsifier muindasitiri yechikafu. Mukuwedzera, mukugadzirira kwemishonga, inogona kushandiswa kudzora kusunungurwa kwemishonga uye kuvandudza maitiro emuviri emapiritsi.
2. Viscosity regulation
Iyo viscosity yemethylcellulose mhinduro inogona kugadziridzwa nekugadzirisa iyo yekuisa, mamorekuru uremu uye tembiricha. Ichi chivakwa chinoita kuti methylcellulose ive yakanaka thickener uye inonamira, inoshandiswa zvakanyanya mukugadzirwa kwezvinhu zvekuvakisa senge simende uye gypsum kuti iwedzere kuita kwayo kuvaka uye kusimba. Panguva imwecheteyo, inogonawo kushandiswa seye rheology control agent yekudhinda ingi uye mapeji kuti ivandudze kushanda kwekuvhara uye kugadzikana kwechigadzirwa.
3. Firimu-kugadzira pfuma
Methylcellulose ine hunyanzvi hwekugadzira firimu uye inogona kugadzira yunifomu, firimu rakajeka rine mamwe masimba emagetsi. Iyi firimu ine mhepo yakanaka yekupinda uye kuchengetedzwa kwemwando, uye inoshandiswa zvakanyanya mufirimu rekudya, mishonga yekuputira zvinhu, uye kumeso kwemasiki substrates muzvizoro. Mafirimu ayo ekugadzira mafirimu haasi kungodzivirira chigadzirwa kubva pakusvibiswa kwekunze, asiwo zvinobudirira kudzora kuchinjana kwehunyoro uye gasi.
4. Biocompatibility uye kuchengeteka
Seselulosi yakagadziridzwa kubva kune yakasarudzika masosi, methylcellulose ine yakanaka biocompatibility uye chengetedzo, uye kazhinji haikonzere allergic reaction kana chepfu. Nokudaro, mukugadzirira kwemishonga, methylcellulose inoshandiswa zvakanyanya mukugadzirwa kwemapiritsi, capsules uye ophthalmic zvinodhaka kuti zvive nechokwadi chekuchengetedzwa uye kushanda kwemishonga. Muchikafu chekudya, methylcellulose, sekuwedzera kwezvokudya, yakave yakasimbiswa sechinhu chakachengeteka nemasangano ekuchengetedza chikafu munyika dzakawanda uye inowanzoshandiswa muzvokudya zvine utano zvakadai sezvokudya zvakaderera-calori uye zvokudya zvisina gluten.
5. Kugadzikana uye kusagadzikana kwemakemikari
Methylcellulose ine kugadzikana kwakanaka kwemakemikari uye inogona kuchengetedza maitiro ayo anoshanda mune ese aridhi uye alkaline nharaunda. Izvi zvinobvumira kuti irambe ichishanda pasi pemamiriro akasiyana-siyana akanyanyisa uye inoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri. Uye zvakare, iyo kemikari inertness yemethylcellulose inoita kuti isanyanya kuita pamwe nezvimwe zvinongedzo, uye inogona kushandiswa sekuzadza kana kudzikamisa mune inoumbwa zvinhu kuwedzera hupenyu hwesherufu yezvigadzirwa uye kuvandudza mashandiro echigadzirwa.
6. Kutora mvura uye kunyorovesa zvinhu
Methylcellulose ine mvura yakanaka yekunyudza uye inonyorovesa zvimiro, uye inogona kutora kakawanda huremu hwayo hwemvura. Naizvozvo, muindasitiri yezvekudya, methylcellulose inoshandiswa seyakanyorovesa kuchengetedza chikafu chakapfava uye chitsva. Muzvigadzirwa zvekuchengetedza munhu, methylcellulose inoshandiswa mumakirimu eganda, shampoos uye zvimwe zvigadzirwa kubatsira ganda nevhudzi kuchengetedza hunyoro uye kupa hunyoro.
7. Kukora uye kumiswa kugadzikana
Methylcellulose inogona kunyatso kuwedzera viscosity yemushonga, kuitira kuti zvimedu zvakasimba zvimire zvakaenzana mumvura kudzivirira kunaya uye stratification. Iyi ficha inoita kuti ive yakakosha kukosha kwekushandisa mukugadzirira kwezvigadzirwa zvakaita sejusi, macondiments, uye kumiswa kwezvinodhaka. Panguva imwecheteyo, inogona zvakare kuvandudza kuravira kwechikafu chemvura uye kuwedzera ruzivo rwevatengi.
8. Thermal kugadzikana uye kupisa kwakanyanya
Methylcellulose ine kugadzikana kwakanaka pakupisa kwakanyanya uye inogona kuchengetedza maitiro ayo anoshanda panguva yekubika nekudziya. Naizvozvo, inoshandiswa zvakanyanya mukugadzirwa kwezvinhu zvakabikwa uye zvakagadzirira-kudya-zvekudya seyakakora uye moisturizer kuve nechokwadi chemhando uye kuravira kwechikafu panguva yekugadziriswa.
9. Eco-ushamwari
Methylcellulose, sechinhu chinoparadza, haina ngozi kune zvakatipoteredza uye inosangana nezvinodiwa zvemazuva ano zvekuchengetedza nharaunda. Inogona kuderedzwa nema microorganisms munzvimbo yechisikigo, kuderedza kukanganiswa kweiyo ecosystem. Naizvozvo, methylcellulose inoonekwa seyakasvibira uye inoshamwaridzana nharaunda zvinhu zveindasitiri, kunyanya muminda yekuvaka uye kurongedza, uko kushandiswa kwayo kunokosha kwezvakatipoteredza.
10. Drug controlled release performance
Methylcellulose ine yakakosha inodzorwa kuburitsa maitiro mukugadzirira kwezvinodhaka. Nekuti inogona kugadzira viscous gel mugastrointestinal turakiti, inogona kuburitsa zvinodhaka zvishoma nezvishoma, kurebesa nguva yekushandiswa kwezvinodhaka, nekuvandudza kushanda kwezvinodhaka. Methylcellulose inowanzo shandiswa kugadzirira mahwendefa anoramba achiburitswa uye microcapsule coatings kukwidziridza kuburitswa kwemishonga, kuderedza kuwanda kwemishonga, uye kuwedzera ruzivo rwevarwere.
Nekuda kweiyo yakasarudzika maitiro ekuita, methylcellulose inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana. Haisi chete yakakosha yekuwedzera inoshanda mumaindasitiri ezvekudya nemishonga, asi zvakare inoita basa rakakosha mumaindasitiri akadai sekuvaka uye zvizorwa. Nekuenderera mberi kwekufambira mberi kwetekinoroji uye nekuwedzera kwezvishandiso, iyo inoshanda zvimiro zvemethylcellulose icharamba ichidzidzwa zvakadzika uye kugadziridzwa kuti ipe mamwe magadzirirwo emaindasitiri akasiyana.
