Methylcellulose (MC) inotorwa kubva ku cellulose kuburikidza ne methylation kurapwa uye ine yakasarudzika yemuviri nemakemikari zvimiro. Sechinhu chinoshandiswa nevakawanda chinoshanda chinowedzera, chinoita basa rakakosha munzvimbo dzakasiyana siyana dzeindasitiri, kusanganisira zvekuvaka, chikafu, mishonga, zvizorwa uye coatings, etc. Iyo yakanakisa thickening, kuchengetwa kwemvura, bonding, film-forming, emulsifying and stabilizing mabasa anoita methylcellulose. chinhu chakakosha mukugadzirisa uye kusimudzira kugadzirwa kwemaindasitiri.
1. Kukora mhedzisiro
Iko kukora zvimiro zvemethylcellulose inoita kuti ive chinhu chakakosha chekuwedzera mumaindasitiri ekuvaka uye ekuputira. Muindasitiri yekuvaka, kunyanya mune simende-yakavakirwa dhaka uye gypsum zvigadzirwa, methylcellulose inogona kuwedzera zvakanyanya kuenderana uye viscosity yefomula, nekudaro ichivandudza kushanda kwezvinhu. Pakuputira uye pendi, kuwedzerwa kwemethylcellulose kunogona kudzivirira zvinobudirira kuti mvura isanyanya kunyorova uye kuwedzera kunamatira uye kufanana kwejasi.
Iyo nzira yekukora inonyanya kuburikidza nekuumbwa kwetiweki chimiro mune mhinduro nemethylcellulose. Iwo mamorekuru maketani emethylcellulose anopindirana kuburikidza nehydrogen zvisungo mumvura kugadzira mhinduro ine imwe viscosity. Ichi chimiro chetiweki chinogona kutora uye kugadzirisa mamorekuru emvura, nekudaro kuwedzera viscosity uye kugadzikana kweiyo mvura system.
2. Kuchengeta mvura
Muzvivakwa zvekuvaka senge simende dhaka uye gypsum slurries, iyo yekuchengetedza mvura zvimiro zvemethylcellulose yakakosha. Zvekuvaka zvinoda huwandu hwakakodzera hwehunyoro kuti utore chikamu mukuita panguva yekurapa. Kurasikirwa kwemvura nguva isati yakwana kuchaita kuti kusakwana kwekurapa kwezvinhu, kuderera kwesimba, kana kuputika pamusoro. Methylcellulose inoumba firimu rakatetepa pamusoro pezvinhu kudzivirira kubuda kwakanyanyisa kwemvura uye kuve nechokwadi chekuti simende, plaster uye zvimwe zvinhu zvine hunyoro hwakakwana panguva yekurapa, nekudaro vachivandudza simba ravo uye kusimba.
Iyi nzira yekuchengetedza mvura inonyanya kukosha munzvimbo dzakaoma kana dzepamusoro-soro, zvichiita kuti methylcellulose iwedzere kushanda kwekugadzirwa kwemaindasitiri pasi pemamiriro ekunze akanyanyisa.
3. Kubatana uye kuwedzera simba rezvinhu
Iyo yekubatanidza zvivakwa zvemethylcellulose zvakare yakanakisa mukugadzirwa kwemaindasitiri. Semuenzaniso, mumatairi ekunamatira uye mamwe marudzi ezvisungo zvekubatanidza, methylcellulose inogona kuvandudza kusungirirwa kwekugadzirisa, zvichiita kuti zvinhu zvinosungirirwa zvibatanidze zviri nani kubasa rekushanda. Iyo yakareba molecular cheni chimiro chemethylcellulose inogona kupindirana neye matrix zvinhu kuti iwedzere simba rekubatanidza, nekudaro ichivandudza iyo yakazara kusimba kwechinyorwa.
Mu fiber-reinforced plastics (FRP), methylcellulose inogona kuwedzera kusimba uye kuoma kwezvinhu zvinoumbwa kuburikidza neiyo fibrous chimiro, ichipa iyo zvinhu zvakakwirira tensile simba uye kupfeka kuramba, nekudaro ichivandudza kusimba kwayo mumaindasitiri ekushandisa. sex.
4. Kuumbwa kwemafirimu
Methylcellulose ine yakanaka yekugadzira firimu kugona mumhinduro, uye ichi chivakwa chave chichishandiswa zvakanyanya muminda yakawanda yemaindasitiri. Muindasitiri yekupfekedza uye pendi, methylcellulose inogona kuumba yunifomu yekudzivirira firimu iyo inowedzera kudzivirira kwemvura uye kushomeka kwemakemikari ekuputira.
Muindasitiri yezvekudya, methylcellulose inowanzoshandiswa mukuvhara kana firimu-kugadzira maitiro, kunyanya mukutsva-kuchengeta kurongedza kwemichero, miriwo uye zvimwe zvekudya. Nekugadzira firimu rakaonda, methylcellulose inononoka kurasikirwa nehunyoro uye inodzivirira chikafu kubva kune kunze nharaunda.
5. Kudzikamisa uye emulsification
Methylcellulose inogona kugadzira mhinduro yepamusoro-viscosity kana yakanyungudutswa mumvura, iyo ine kugadzikana uye emulsifying mhedzisiro. Iyi pfuma inonyanya kukosha mumaindasitiri akadai semachira, pendi, zvizorwa uye kugadzirira kwemishonga. Mune pendi uye pendi, methylcellulose inogona kudzikamisa kupararira kwemavara, kudzivirira kugadzirisa, uye kuvandudza kupenya uye kufanana kwejasi; mukuumbwa kwezvizoro, methylcellulose inoshanda semulsifier kudzikamisa iyo mvura-oiri yakasanganiswa system uye kudzivirira Stratification inoitika.
Mukugadzirira kwemishonga, methylcellulose inowanzoshandiswa kukora uye kudzikamisa gadziriro yemvura yemumuromo uye semutakuri wemishonga. Viscosity yayo uye firimu-kugadzira zvimiro zvinogona kubatsira mushonga kuburitswa zvishoma nezvishoma, kuwedzera nguva yekushandiswa kwezvinodhaka, nekuvandudza bioavailability yemushonga.
6. Thermal gelling properties
Chinhu chakakosha chemuviri chemethylcellulose ndiyo yakasarudzika yekupisa gelling maitiro, iyo inoshanduka kuita gel kana ichipisa. Hunhu uhu hunoita kuti dzisadzorereke mune mamwe maindasitiri akakosha magadzirirwo. Semuenzaniso, muindasitiri yezvekudya, methylcellulose inoshandiswa kugadzira chikafu chakaderera-mafuta. Iyo gel inoumbwa mushure mekupisa ine kuravira kwakafanana nemafuta, zvichibvumira kudya kwakaderera-mafuta kuchengetedza kunaka kwakanaka uye kugadzirwa. Muindasitiri yekuvaka, iyi thermal gelling pfuma inovandudza kusimba uye kugadzikana kwezvinhu zvekuvaka munzvimbo dzepamusoro-tembiricha.
7. Biocompatibility uye kushamwaridzana kwezvakatipoteredza
Methylcellulose, semusanganiswa wakasikwa, ine biocompatibility yakanaka uye kushamwaridzana kwezvakatipoteredza. Izvi zvinoita kuti iwedzere kufarirwa mune zvemazuva ano maindasitiri ekugadzira, kunyanya munzvimbo dzine zvakakwirira kuchengetedzwa kwezvakatipoteredza zvinodiwa, senge zvivakwa zvakasvibira, ecological coatings uye zvinoparara zvekurongedza zvinhu. Methylcellulose inogona kuderedzwa zvakasikwa, ichidzikisa mutoro wezvakatipoteredza uye kuenderana nemaitiro emaindasitiri ekusimudzira kwakasimba.
8. Kuvandudza kushanda kwekugadzirisa
Mukugadzirwa kwemaindasitiri, methylcellulose inogona kuvandudza kushanda zvakanaka. Semuenzaniso, mune zvekuvaka, methylcellulose inogona kuwedzera fluidity uye kuchengetwa kwemvura kwezvinhu, nekudaro kuvandudza kuve nyore uye kugona kwekuvaka; mune zvekuzora uye kugadzirira kwemishonga, methylcellulose inogona kuvandudza kugadzikana kwemafomula uye kuderedza kunaya kwemvura. uye delamination, nekudaro ichiwedzera hupenyu hwesherufu yechigadzirwa. Izvi zvivakwa zvinobvumira methylcellulose kuvandudza zvakanyanya kugadzirwa kwekuita uku uchikwenenzvera maindasitiri ekugadzira.
Sekuwedzera kwemaitiro akawanda, methylcellulose inoshandiswa mumaindasitiri akawanda akadai sekuvaka, chikafu, mishonga, cosmetics, coatings, nezvimwewo nekuda kwemaitiro ayo akawanda akadai sekukora, kuchengetedza mvura, kusungirirwa, kugadzira firimu, kudzikamisa, emulsification uye thermal gelling. inoita basa rinokosha mumunda. Iyo haingogone chete kusimudzira zvimiro zvemuviri zvemaindasitiri ekugadzira, asi zvakare kuvandudza kugadzirwa kwakanaka uye kusangana zvakasiyana siyana maindasitiri. Panguva imwecheteyo, iyo biocompatibility uye kushamwaridzana kwezvakatipoteredza kwemethylcellulose zvakare inoita kuti ive chinhu chakanakisa chinosangana nezvinodiwa zvekusimudzira. Nekushandisa zvine hungwaru kushandisa methylcellulose mukugadzirwa kwemaindasitiri, haingogone kuvandudza mhando yechigadzirwa, asi zvakare kukurudzira kufambira mberi nekusimudzira kwehunyanzvi hweindasitiri.
