Methylcellulose (MC) chinhu chinobva mu cellulose kuburikidza nekurapa methylation uye ine hunhu hwakasiyana hwemuviri nemakemikari. Sechinowedzerwa chinoshandiswa zvakanyanya, chinoita basa rakakosha mumabasa akasiyana-siyana emaindasitiri, kusanganisira zvekuvaka, chikafu, mishonga, zvizoro uye machira, nezvimwewo. Kukora kwayo kwakanaka, kuchengetedza mvura, kubatana, kugadzira mafirimu, emulsifying uye kugadzikana kunoita kuti methylcellulose ive chinhu chakakosha mukugadzirisa nekuvandudza maformula eindasitiri.
1. Kusimba kwemhedzisiro
Kusimba kwe methylcellulose kunoita kuti ive chinhu chakakosha muindasitiri yekuvaka nekugadzira machira. Muindasitiri yekuvaka, kunyanya muzvigadzirwa zvemortar yakagadzirwa nesimende negypsum, methylcellulose inogona kuwedzera kuenderana uye kusimba kwefomula, nokudaro ichivandudza kushanda kwechinhu chacho. Kune machira nependi, kuwedzerwa kwe methylcellulose kunogona kudzivirira mvura kuti isanyanya kunyorova uye kuwedzera kunamira uye kufanana kwejira racho.
Maitiro ekukora anonyanya kuitwa kuburikidza nekuumbwa kwechimiro chenetwork mumushonga nemethylcellulose. Maketani emamolecular emethylcellulose anosangana kuburikidza nemahydrogen bonds mumvura kuti agadzire mhinduro ine viscosity yakati. Chimiro ichi chenetwork chinogona kubata nekugadzirisa mamorekuru emvura, nokudaro zvichiwedzera viscosity uye kugadzikana kwe liquid system.
2. Kuchengetwa kwemvura
Muzvinhu zvekuvaka zvakaita semamota esimende nemaslurry egypsum, hunhu hwe methylcellulose hwekuchengetedza mvura hwakakosha. Zvinhu zvekuvaka zvinoda hunyoro hwakakodzera kuti zvibatanidzwe mukuita kwekugadzirisa panguva yekupisa. Kurasikirwa nemvura nguva isati yakwana kuchaita kuti zvinhu zvisanyatsosimba, simba risadzikire, kana kuti zvitsemuke pamusoro. Methylcellulose inoita firimu rakatetepa pamusoro pechinhu ichi kudzivirira kupwanya kwemvura zvakanyanya uye kuona kuti simende, plaster nezvimwe zvinhu zvine hunyoro hwakakwana panguva yekupisa, nokudaro zvichivandudza simba razvo uye kugara kwenguva refu.
Kuchengetedza mvura uku kwakakosha zvikuru munzvimbo dzakaoma kana dzinopisa zvakanyanya, zvichibvumira methylcellulose kuti ikwanise kuita zvakanaka mukugadzirwa kwemaindasitiri mumamiriro ezvinhu akaoma.
3. Kubatanidza nekusimudzira simba rezvinhu
Hunhu hwekubatanidza hwemethylcellulose hwakanakawo mukugadzirwa kwemaindasitiri. Semuenzaniso, muma tile glues nedzimwe mhando dze bonding agents, methylcellulose inogona kunatsiridza kunamira kwechimiro, zvichiita kuti zvinhu zve bonding zvinamire zviri nani panzvimbo yebasa. Maumbirwo marefu e methylcellulose anogona kushanda pamwe chete nezvinhu zve matrix kuti awedzere simba rekubatanidza, nokudaro achivandudza simba rekuvaka rechinhu chacho.
Mumapurasitiki akasimbiswa nefiber (FRP), methylcellulose inogona kuwedzera simba uye kusimba kwezvinhu zvakasanganiswa kuburikidza nechimiro chayo chefiber, zvichiita kuti chinhu chacho chive nesimba rakawanda rekudhonza uye kuramba kupfeka, nokudaro zvichivandudza kugara kwacho mumaindasitiri.
4. Kugadzirwa kwemafirimu
Methylcellulose ine kugona kwakanaka kwekugadzira firimu mukugadzirisa, uye hunhu uhwu hwave huchishandiswa zvakanyanya mumaindasitiri akawanda. Muindasitiri yekupenda nekupenda, methylcellulose inogona kugadzira firimu rinodzivirira rakaenzana rinowedzera kudzivirira mvura uye kuramba makemikari kwekupenda.
Muindasitiri yechikafu, methylcellulose inowanzoshandiswawo mukuputira kana kugadzira firimu, kunyanya mukurongedza michero, miriwo nezvimwe zvekudya zvitsva. Nekugadzira firimu rakatetepa, methylcellulose inononoka kurasikirwa nehunyoro uye inodzivirira chikafu kubva kunharaunda yekunze.
5. Kugadzikana uye emulsification
Methylcellulose inogona kugadzira mhinduro ine viscosity yakakura kana yakanyungudutswa mumvura, iyo ine simba rekusimbisa uye kusimbisa. Hunhu uhwu hwakakosha zvikuru mumaindasitiri akadai sekuputira, pendi, zvizoro uye kugadzira mishonga. Mupendi nependi, methylcellulose inogona kudzikamisa kupararira kwepigment, kudzivirira kugadzika, uye kunatsiridza kupenya uye kufanana kwependi; mumafomu ekushongedza, methylcellulose inoshanda se emulsifier yekudzikamisa system yakasanganiswa yemafuta emvura uye kudzivirira Stratification kuitika.
Mukugadzira mishonga, methylcellulose inowanzo shandiswa kukora uye kudzikamisa zvigadzirwa zvemvura inonwiwa uye semutakuri wemishonga. Hunhu hwayo hwekusimba uye kugadzira firimu zvinogona kubatsira mushonga kuburitswa zvishoma nezvishoma, kuwedzera nguva yekushanda kwemushonga, uye kuvandudza kuwanikwa kwemushonga.
6. Hunhu hwekupisa kwemafuta
Chinhu chakakosha che methylcellulose maitiro ayo akasiyana ekupisa gelling, ayo anoshanduka kuita gel kana yapiswa. Hunhu uhwu hunoita kuti isatsiviwe mune mamwe maindasitiri akakosha. Semuenzaniso, muindasitiri yezvikafu, methylcellulose inoshandiswa kugadzira chikafu chine mafuta mashoma. Gel inogadzirwa mushure mekupiswa ine kuravira kwakafanana nemafuta, zvichibvumira chikafu chine mafuta mashoma kuchengetedza kunaka kwakanaka uye magadzirirwo akanaka. Muindasitiri yekuvaka, hunhu uhwu hwekupisa gelling hunovandudza kugara kwenguva refu uye kugadzikana kwezvinhu zvekuvaka munzvimbo dzinopisa zvakanyanya.
7. Kuenderana kwezvinhu zvipenyu uye hushamwari kune zvakatipoteredza
Methylcellulose, semusanganiswa unobva muzvisikwa, ine hukama hwakanaka nehupenyu uye hushamwari nezvakatipoteredza. Izvi zvinoita kuti iwedzere kufarirwa mumaindasitiri emazuva ano, kunyanya munzvimbo dzine zvinodiwa zvakanyanya zvekuchengetedza nharaunda, zvakaita sezvivakwa zvakasvibira, machira ekuchengetedza nharaunda uye zvinhu zvinopakira zvinoora. Methylcellulose inogona kuora, zvichideredza mutoro wezvakatipoteredza uye zvichitevedzera maitiro emaindasitiri ekusimudzira nharaunda.
8. Kuvandudza mashandiro ekugadzirisa
Mukugadzirwa kwemaindasitiri, methylcellulose inogona kuvandudza mashandiro ekugadzira. Semuenzaniso, muzvinhu zvekuvaka, methylcellulose inogona kuwedzera kuyerera uye kuchengetwa kwemvura kwezvinhu, nokudaro ichivandudza nyore uye kushanda zvakanaka kwekuvaka; muzvizoro nemishonga, methylcellulose inogona kuvandudza kugadzikana kwemafomura uye kuderedza kunaya kwemvura uye kuchenesa, nokudaro ichiwedzera hupenyu hwesherufu yechigadzirwa. Hunhu uhwu hunobvumira methylcellulose kuvandudza zvakanyanya kushanda zvakanaka kwekugadzira uku uchivandudza mashandiro emaindasitiri.
Sechinowedzerwa chinoshanda zvakawanda, methylcellulose inoshandiswa mumaindasitiri akawanda akadai sekuvaka, chikafu, mishonga, zvizoro, machira, nezvimwewo nekuda kwehunhu hwayo hwakawanda hwakadai sekukora, kuchengetedza mvura, kubatana, kugadzira mafirimu, kugadzikana, emulsification uye thermal gelling. Inotamba basa rakakosha mumunda uyu. Haingogone kungovandudza hunhu hwemagadzirirwo emaindasitiri chete, asiwo inovandudza kushanda zvakanaka kwekugadzira uye kusangana nezvinodiwa zvakasiyana-siyana zvemaindasitiri. Panguva imwe chete, kuenderana kwe methylcellulose uye hushamwari hwezvakatipoteredza zvinoitawo kuti ive chinhu chakakodzera chinosangana nezvinodiwa zvekusimudzira magariro. Nekushandisa methylcellulose zvine musoro mumafomu eindasitiri, haingogone chete kuvandudza mhando yechigadzirwa, asiwo kukurudzira kufambira mberi nekuvandudzwa kwetekinoroji yemaindasitiri.
