Thaj chaw ntawm methyl cellulose

Methyl Cellulose (MC) yog cov polymer ntau yam los ntawm cellulose los ntawm cellulose los ntawm cellulose, muaj ntau ntau cov khoom uas ua rau nws muaj txiaj ntsig hauv ntau cov ntawv siv thiab kev lag luam. Nov yog qee qhov tseem ceeb ntawm methyl cellulose:

1. Solubility: Methyl cellulose yog soluble hauv dej txias thiab qee cov kuab tshuaj organic xws li Methanol thiab ethanol. Nws ua cov kev daws teeb meem meej, cov kev daws teeb meem thaum tawg hauv dej, uas tuaj yeem hloov kho los ntawm kev kho kom haum thiab kub.
2. Viscosity: Methyl cellulose kev daws teeb meem siab nthuav dav, uas tuaj yeem hloov kho los ntawm kev sib txawv xws li lub cev hnyav li molecular, thiab kub. Cov qhab nia hnyav dua thiab qib siab dua feem ntau yuav ua rau muaj txiaj ntsig zoo.
3. Zaj duab xis-tsim muaj peev xwm: methyl cellulose muaj peev xwm los tsim cov yeeb yaj kiab thiab pob tshab cov yeeb yaj kiab thaum ziab los ntawm kev daws teeb meem. Cov cuab yeej no ua rau nws haum rau cov ntawv thov xws li txheej, cov nplaum, thiab cov yeeb yaj kiab uas muaj cov yeeb yaj kiab.
4. Thermal Stability: cellulose cellulose yog qhov ruaj khov tshaj li siv nyob rau hauv cov ntawv thov uas muaj cov ntsiav tshuaj kub, kub yaj.
5. Tshuaj lom neeg ruaj khov: methyl cellulose yog tiv taus kev ua phem los ntawm cov kua qaub, alkalis, thiab oxidizing cov neeg sawv cev nyob rau hauv ib txwm muaj mob. Cov tshuaj no ruaj ruaj rau nws txoj kev ua kom ntev thiab haum rau kev siv hauv ntau qhov chaw.
6. Hydrophilicity: Methyl cellulose yog hydrophilic, lub ntsiab lus nws muaj kev muaj zog muaj zog rau dej. Nws tuaj yeem nqus thiab khaws cov dej ntau, ua rau nws cov thickening thiab ruaj khov muaj cov kev daws teeb meem aqueous.
7. Tsis-toxicity: methyl cellulose yog suav hais tias tsis muaj tshuaj lom thiab muaj kev nyab xeeb rau kev siv hauv cov zaub mov, tshuaj siv, thiab cov ntawv thov kom hniav zoo nkauj. Nws yog feem ntau pom tau tias muaj kev nyab xeeb (gras) los ntawm kev tswj hwm thaum siv tsis pub dhau cov kev txwv.
8. Biodegradity: methyl cellulose yog biodegradable, lub ntsiab lus nws tuaj yeem tawg los ntawm cov kab mob me me hauv ib puag ncig. Cov cuab yeej no txo ​​qhov kev cuam tshuam ib puag ncig thiab pab txhawb nqa cov khoom pov tseg uas muaj cov tshuaj methyl me me.
9. Compatibility nrog cov quav tshuaj ntxiv: methyl cellulose tau sib haum nrog ntau yam ntawm cov quav ntxiv, suav nrog cov hnab yas, surfactants, pigments, thiab fillers. Cov tshuaj ntxiv no tuaj yeem koom nrog rau hauv methyl cellulose tsim kho kom hloov nws cov khoom rau cov kev siv tshwj xeeb.
10. Adhesion thiab kev khi lus: methyl cellulose ua rau cov khoom nplaum zoo thiab cov khoom siv hauv cov ntawv sau ua ke, tshuaj khib, thiab cov tshuaj pleev ntsej muag.

Methyl cellulose rau nws cov solubility, thincosity, cov yeeb yam hluav taws xob, cov kuab lom, biodegradabity, thiab compatibility nrog cov quav ntxiv. Cov khoom no ua rau nws muaj ntau yam polymer nrog ntau daim ntawv thov hauv kev lag luam hauv kev lag luam, khoom noj, cov tshuaj pleev, khoom siv, thiab ntawv.
