Ethyl Cellulose

Ethyl cellulose yog ib qho tseem ceeb ntawm cellulose, lub ntuj polymer pom hauv cov nroj tsuag. Nws yog tsim los ntawm cov tshuaj tiv thaiv ntawm cellulose nrog ethyl chloride nyob rau hauv muaj ib tug catalyst. Ethyl cellulose tau siv dav hauv ntau yam kev lag luam vim nws cov khoom tshwj xeeb thiab versatility. Ntawm no yog qee cov yam ntxwv tseem ceeb thiab kev siv ntawm Ethyl cellulose:

1. Insolubility hauv dej: Ethyl cellulose yog insoluble hauv dej, uas ua rau nws haum rau cov ntawv thov uas cov dej tsis kam. Cov cuab yeej no tseem tso cai rau nws siv los ua cov txheej tiv thaiv hauv cov tshuaj thiab ua cov khoom thaiv hauv cov khoom siv khoom noj.
2. Solubility hauv Organic cov kuab tshuaj: Ethyl cellulose yog soluble nyob rau hauv ntau ntawm organic cov kuab tshuaj, suav nrog ethanol, acetone, thiab chloroform. Qhov solubility no ua rau nws yooj yim rau cov txheej txheem thiab ua rau ntau yam khoom, xws li txheej, cov yeeb yaj kiab, thiab inks.
3. Zaj duab xis-tsim muaj peev xwm: Ethyl cellulose muaj peev xwm los ua cov duab hloov tau thiab cov yeeb yaj kiab ruaj khov thaum ziab. Cov cuab yeej no yog siv hauv cov ntawv thov xws li cov txheej txheem txheej txheem ntawm cov tshuaj, qhov chaw nws muab cov txheej tiv thaiv rau cov khoom xyaw nquag.
4. Thermoplastic cwj pwm thermoplastic tus cwj pwm, lub ntsiab lus nws tuaj yeem softened thiab rhuab thiab ua kom txias thaum txias. Cov cuab yeej no ua rau nws haum rau siv nyob rau hauv kub-melt adhesives thiab mapable plastics.
5. Tshuaj lom neeg INTERTENT: Ethyl Cellulose yog siv tshuaj lom thiab tiv taus cov kua qaub, alkalis, thiab feem ntau cov kuab tshuaj. Cov cuab yeej no ua rau nws haum rau kev siv hauv cov qauv uas ruaj khov thiab sib xyaw nrog lwm cov khoom xyaw yog qhov tseem ceeb.
6. Biocompatibility: Ethyl cellulose feem ntau yog pom tias muaj kev nyab xeeb (Gras) rau kev siv hauv cov khoom lag luam, khoom noj, thiab khoom noj kom zoo nkauj. Nws tsis yog-lom thiab tsis ua rau muaj kev pheej hmoo ntawm kev tsis zoo thaum siv raws li npaj siab.
7. Kev tso tawm hluav taws xob: Ethyl cellulose feem ntau siv hauv cov tshuaj tsim kho kom tswj cov khoom xyaw nquag. Los ntawm kev kho cov tuab ntawm cov tshuaj tua kab mob ntawm cov ntsiav tshuaj lossis cov pellets, cov nqi tshuaj yuav hloov kho kom tiav lossis tshem tawm cov khoom xa tawm txuas ntxiv.
8. Binder thiab tuab: Ethyl cellulose yog siv los ua cov binder thiab thickener hauv ntau daim ntawv thov, suav nrog inks, txheej, thiab cov nplaum. Nws txhim kho cov khoom ntawm cov khoom ntawm cov qauv thiab pab ua tiav kev xav tau zoo thiab viscosity.

Cov cellulose Ethylas yog ib qho kev siv ntau yam hauv kev lag luam xws li cov tshuaj, zaub mov, tshuaj pleev ib ce, thiab cov nplaum. Nws tshwj xeeb ua ke ntawm cov khoom ua rau nws muaj txiaj ntsig zoo hauv ntau tus qauv, uas nws ua rau muaj kev ruaj khov, thiab kev ua haujlwm.
