Methyl-Hydroxyethylcellulose | CAS 9032-42-2

Methyl Hydroxyethylcellulose (MHEC) yog ib qho cellulose derivative nrog cov tshuaj mis (C6H10O5)n. Nws yog muab los ntawm cellulose, ib qho polymer uas tshwm sim ntuj pom nyob rau hauv cov phab ntsa cell ntawm cov nroj tsuag. MHEC yog synthesized los ntawm kev hloov kho tshuaj ntawm cellulose, qhia ob qho tib si methyl thiab hydroxyethyl pawg rau ntawm cellulose backbone.

Nov yog qee cov ntsiab lus tseem ceeb txog Methyl Hydroxyethylcellulose:

1. Cov Qauv Tshuaj: MHEC yog cov polymer uas yaj tau hauv dej nrog cov qauv zoo ib yam li cellulose. Kev ntxiv cov pawg methyl thiab hydroxyethyl ua rau cov polymer no muaj cov yam ntxwv tshwj xeeb, suav nrog kev yaj tau zoo dua hauv dej thiab ua kom tuab dua.
2. Cov Khoom: MHEC muaj cov yam ntxwv zoo heev uas ua rau tuab, ua zaj duab xis, thiab khi, ua rau nws haum rau ntau yam kev siv. Nws feem ntau siv ua cov khoom ua kom tuab, cov khoom ruaj khov, thiab cov khoom hloov pauv viscosity hauv ntau yam lag luam, suav nrog kev tsim kho, tshuaj, kev saib xyuas tus kheej, thiab cov tshuaj pleev xim.
3. Tus lej CAS: Tus lej CAS rau Methyl Hydroxyethylcellulose yog 9032-42-2. Tus lej CAS yog cov lej cim tshwj xeeb uas tau muab rau cov tshuaj lom neeg los pab txheeb xyuas thiab taug qab hauv cov ntaub ntawv tshawb fawb thiab cov ntaub ntawv tswj hwm.
4. Daim Ntawv Thov: MHEC pom muaj kev siv dav hauv kev lag luam kev tsim kho ua tus neeg sawv cev ua kom tuab hauv cov cement-based mortars, cov nplaum pobzeb, thiab cov ntaub ntawv gypsum. Hauv cov tshuaj thiab cov khoom siv tu tus kheej, nws yog siv ua tus binder, zaj duab xis former, thiab viscosity modifier hauv cov tshuaj pleev xim, cov tshuaj pleev qhov muag, tshuaj pleev, tshuaj pleev, thiab tshuaj zawv plaub hau.
5. Txoj Cai Tswjfwm: Methyl Hydroxyethylcellulose feem ntau suav tias muaj kev nyab xeeb (GRAS) rau nws cov kev siv hauv ntau yam lag luam. Txawm li cas los xij, cov kev cai tshwj xeeb yuav txawv nyob ntawm lub tebchaws lossis thaj chaw siv. Nws yog ib qho tseem ceeb kom ua raws li cov cai thiab cov lus qhia thaum tsim cov khoom uas muaj MHEC.

Zuag qhia tag nrho, Methyl Hydroxyethylcellulose yog ib qho cellulose derivative uas muaj ntau yam khoom muaj nqis rau ntau yam kev siv hauv kev lag luam thiab kev lag luam. Nws lub peev xwm los txhim kho cov khoom rheological ntawm cov formulations ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ua tiav cov yam ntxwv kev ua tau zoo hauv ntau yam khoom.
