Methyl-Hydroxyethylcellulose | CAS 9032-42-2 Nr

Methyl Hydroxyethylcellulose (MHEC) yog cellulose derivative nrog cov tshuaj formula (C6H10O5)n. Nws yog muab los ntawm cellulose, ib txwm tshwm sim polymer pom nyob rau hauv lub cell phab ntsa ntawm cov nroj tsuag. MHEC yog tsim los ntawm kev hloov kho tshuaj ntawm cellulose, qhia ob pawg methyl thiab hydroxyethyl mus rau cov pob txha cellulose.

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

1. Chemical Structure: MHEC yog cov dej-soluble polymer nrog cov qauv zoo ib yam li cov cellulose. Qhov sib ntxiv ntawm methyl thiab hydroxyethyl pawg muab cov khoom tshwj xeeb rau cov polymer, nrog rau kev txhim kho solubility hauv dej thiab txhim kho lub peev xwm thickening.
2. Cov Khoom: MHEC nthuav tawm cov thickening zoo heev, ua yeeb yaj kiab, thiab khi cov khoom, ua rau nws tsim nyog rau ntau yam kev siv. Nws yog feem ntau siv los ua cov thickener, stabilizer, thiab viscosity modifier nyob rau hauv ntau yam lag luam, nrog rau kev tsim kho, tshuaj, kev tu tus kheej, thiab txheej.
3. CAS Naj Npawb: 9032-42-2 CAS No. CAS tus lej yog tus lej cim tshwj xeeb uas tau muab rau cov tshuaj lom neeg los pab txhawb kev txheeb xyuas thiab taug qab hauv cov ntaub ntawv tshawb fawb thiab cov ntaub ntawv tswj hwm.
4. Daim ntaub ntawv: MHEC pom kev siv dav hauv kev tsim kho kev lag luam raws li tus neeg sawv cev thickening hauv cement-based mortars, pobzeb nplaum, thiab cov ntaub ntawv gypsum. Hauv cov chaw muag tshuaj thiab cov khoom tu tus kheej, nws yog siv los ua ib daim ntawv khi, zaj duab xis qub, thiab cov viscosity modifier hauv cov ntsiav tshuaj txheej, tshuaj kho qhov muag, tshuaj pleev, tshuaj pleev, thiab tshuaj zawv plaub hau.
5. Regulatory Status: Methyl Hydroxyethylcellulose feem ntau suav hais tias muaj kev nyab xeeb (GRAS) rau nws cov kev npaj siv hauv ntau yam lag luam. Txawm li cas los xij, cov kev cai tshwj xeeb yuav txawv nyob ntawm lub teb chaws lossis cheeb tsam ntawm kev siv. Nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov cai thiab cov lus qhia cuam tshuam thaum tsim cov khoom uas muaj MHEC.

Zuag qhia tag nrho, Methyl Hydroxyethylcellulose yog ntau yam cellulose derivative nrog cov khoom muaj txiaj ntsig rau ntau yam kev lag luam thiab kev lag luam. Nws lub peev xwm los txhim kho cov khoom rheological ntawm formulations ua rau nws nyiam xaiv rau kev ua tiav cov yam ntxwv ntawm kev ua tau zoo hauv ntau yam khoom.
