Ethylcellulose yog ntau yam polymer nrog ntau yam kev siv hauv ntau yam lag luam.Nws cov khoom tshwj xeeb tso cai rau nws siv rau hauv txhua yam ntawm cov tshuaj mus rau zaub mov, txheej rau textiles.
Taw qhia rau ethylcellulose:
Ethylcellulose yog derivative ntawm cellulose, ib tug natural polymer pom nyob rau hauv cov nroj tsuag.Nws yog synthesized los ntawm reacting cellulose nrog ethyl chloride nyob rau hauv lub xub ntiag ntawm lub hauv paus xws li sodium hydroxide.Cov txheej txheem no tsim cov polymer uas cov pawg ethyl txuas nrog hydroxyl pawg ntawm cov pob txha cellulose.
Cov yam ntxwv ntawm ethylcellulose:
Thermoplasticity: Ethylcellulose nthuav tawm tus cwj pwm thermoplastic, uas txhais tau tias nws softens thaum rhuab thiab solidifies thaum txias.
Kev tsim cov yeeb yaj kiab: Tom qab tau yaj hauv cov kuab tshuaj tsim nyog, lub pob tshab, hloov tau yooj yim tuaj yeem tsim.
Insoluble hauv dej: Tsis zoo li cellulose, ethylcellulose yog insoluble hauv dej tab sis soluble nyob rau hauv ntau yam organic solvents xws li cawv, esters thiab chlorinated hydrocarbons.
Chemical stability: Nws muaj tshuaj lom neeg ruaj khov thiab tuaj yeem tiv taus degradation los ntawm acids, alkalis thiab oxidants.
Kev siv cov tshuaj ethylcellulose:
1. Tshuaj:
Txheej: Ethylcellulose yog dav siv los ua txheej rau cov tshuaj ntsiav tshuaj thiab tshuaj.Nws cov khoom tsim ua yeeb yaj kiab muab kev tiv thaiv kev tiv thaiv, tswj kev tso tawm ntawm cov khoom xyaw nquag, daim npog qhov ncauj saj thiab txhim kho swallowability.
Sustained-release formulations: Vim nws muaj peev xwm tswj tau cov tshuaj tso tawm, ethylcellulose tuaj yeem siv los tsim cov qauv tsim tawm-tso tawm thiab tso tawm kom ntseeg tau tias muaj kev kho mob ntev thiab txo qhov zaus ntawm kev noj tshuaj.
Binder: Nws yog siv los ua cov ntawv khi rau hauv cov ntsiav tshuaj formulations los pab ua kom cov hmoov sib tov rau hauv daim ntawv ntau npaum li cas nrog rau qhov yuav tsum tau muaj zog.
2. Khoom noj khoom haus kev lag luam:
Edible Coatings: Ethylcellulose yog siv nyob rau hauv kev lag luam khoom noj khoom haus los ua edible coatings rau txiv hmab txiv ntoo, zaub thiab confectionery khoom.Cov txheej txheem no txhim kho cov tsos, ua kom lub neej ntev thiab tiv thaiv kom tsis txhob ya raws thiab kab mob microbial.
Kev hloov rog rog: Hauv cov zaub mov tsis muaj rog lossis tsis muaj rog, ethylcellulose tuaj yeem siv los ua cov rog hloov, ua raws li kev ntxhib los mos thiab lub qhov ncauj ntawm cov rog thiab txhim kho tag nrho cov kev paub dhau los.
3. Coatings thiab inks:
Xim thiab Varnishes: Ethylcellulose yog cov khoom tseem ceeb hauv cov xim, cov kua roj vanish thiab cov kua roj vanish uas nws yog siv los ua ib zaj duab xis qub, nplaum thiab thickener.Nws muab cov xim zoo heev adhesion, tshuaj tiv thaiv thiab gloss.
Printing Inks: Hauv kev lag luam luam ntawv, ethylcellulose yog siv los tsim cov inks rau ntau yam txheej txheem luam ntawv, suav nrog flexographic, gravure, thiab tshuaj ntsuam luam ntawv.Nws txhim kho tus cwj mem adhesion, viscosity tswj thiab pigment dispersion.
4. Cov khoom tu tus kheej:
Tshuaj pleev ib ce: Ethylcellulose yog siv los ua cov thickener, stabilizer thiab zaj duab xis-tsim tus neeg sawv cev hauv cov tshuaj pleev ib ce xws li cream, tshuaj pleev ib ce thiab khoom tu plaub hau.Nws txhim kho cov khoom zoo nkauj, txhim khu kev sib kis, thiab muab kev xav zoo, tsis muaj roj.
Sunscreen Formulations: Nyob rau hauv cov tshuaj pleev thaiv hnub thiab cov khoom tiv thaiv tshav ntuj, ethylcellulose pab stabilize UV lim, txhim kho cov dej tsis kam, thiab tsim ib zaj duab xis rau ntawm daim tawv nqaij kom zoo tiv thaiv tshav ntuj.
5. Textile kev lag luam:
Textile Sizing: Ethylcellulose yog siv nyob rau hauv textile sizing formulations los txhim kho cov xov paj zog, abrasion kuj thiab weaving efficiency.Nws tsim cov txheej txheej tiv thaiv ntawm cov fibers, txhawb kev ua kom zoo dua qub thiab txhim kho cov ntaub zoo.
Printing paste: Nyob rau hauv textile printing, ethyl cellulose yog ntxiv rau cov luam ntawv paste los txhim kho cov luam ntawv clarity, xim ceev ceev thiab washability ntawm ntau yam ntaub ntawv substrates.
6. Lwm yam kev siv:
Adhesives: Ethylcellulose yog siv los tsim cov nplaum thiab cov khoom sib khi rau cov ntawv sib txuas, ntoo, yas thiab hlau.Nws txhim kho daim ntawv cog lus muaj zog, nplaum thiab yoog raws.
Ceramics: Hauv kev lag luam ceramics, ethyl cellulose yog ntxiv rau ceramic slurries thiab glazes los kho rheological zog, tiv thaiv los nag, thiab txhim kho nto smoothness thaum tua.
Ethylcellulose yog ntau yam polymer nrog ntau yam kev siv hauv ntau qhov kev lag luam.Nws cov khoom sib xyaw ua ke tshwj xeeb, suav nrog kev ua yeeb yaj kiab muaj peev xwm, cov khoom solubility thiab tshuaj lom neeg ruaj khov, ua rau nws tseem ceeb hauv cov tshuaj, khoom noj, txheej, khoom tu tus kheej, textiles thiab lwm yam.Raws li kev siv thev naus laus zis thiab cov qauv tshiab tau tsim, kev siv ethylcellulose yuav tsum txuas ntxiv nthuav dav, tsav kev tsim kho tshiab thiab txhim kho cov khoom lag luam hauv kev siv sib txawv.
