Ethyl cellulose (EC)
Nkọwa ngwaahịa
Ethyl Cellulose (EC) bụ ihe na-adịghị atọ ụtọ, nke na-enweghị atụ, na-acha ọcha na-acha ọcha na-acha ọcha. A na-eji ya na gels suntan, ude, na lotions. Nke a bụ ethyl ether nke cellulose.Ethyl Cellulose EC bụ soluble na a dịgasị iche iche nke organic solvents. A na-eji Ethyl Cellulose EC mee ihe dị ka ihe na-adịghị agwụ agwụ, ihe na-adịghị edozi na matriks ma ọ bụ usoro mkpuchi.
Enwere ike iji Ethyl Cellulose EC kpuchie otu ma ọ bụ karịa ihe na-arụ ọrụ nke mbadamba nkume iji gbochie ha iji ihe ndị ọzọ ma ọ bụ ibe ha meghachi omume. Ọ nwere ike igbochi discoloration nke mfe oxidizable bekee dị ka ascorbic acid, ikwe granulations maka mfe abịakọrọ mbadamba na ndị ọzọ usoro onunu ogwu ụdị.EC nwere ike iji ya n'onwe ya ma ọ bụ na Nchikota na mmiri-soluble components iji kwadebe nọgidere ntọhapụ film mkpuchi na-ugboro ugboro na-eji maka. mkpuchi nke micro-particles, pellets na mbadamba.
Ethyl cellulose enweghị ike igbari na mmiri, ma soluble na ọtụtụ organic solvents, ya mere EC eji na mbadamba, granules nke nrapado gị n'ụlọnga. Ọ nwere ike dịkwuo ike nke mbadamba nkume iji belata friability mbadamba, ọ nwere ike na-eji dị ka film-akpụ gị n'ụlọnga iji melite ọdịdị nke mbadamba nkume, dịpụrụ adịpụ uto, iji zere ọdịda nke mmiri nwere mmetụta ọgwụ ọjọọ iji gbochie mbanye nke metamorphic mgbanwe mmadụ, na-akwalite. nchekwa nchekwa nke mbadamba nkume, nwekwara ike iji dị ka ihe na-agba ume maka mbadamba ihe ntọhapụ na-adịgide adịgide.

Ngwa
Ethyl cellulose bụ resin na-arụ ọtụtụ ọrụ. Ọ na-arụ ọrụ dị ka ihe nkedo, thickener, rheology modifier, ihe nkiri mbụ, na mgbochi mmiri n'ọtụtụ ngwa dị ka akọwara n'okpuru:
Adhesives: A na-eji Ethyl Cellulose eme ihe n'ọtụtụ ebe na agbaze ọkụ na ihe mgbaze ndị ọzọ na-eme ka ihe mgbaze na-eme ka ọ bụrụ ezigbo thermoplasticity na ike akwụkwọ ndụ akwụkwọ ndụ. Ọ bụ soluble na-ekpo ọkụ polymers, plasticizers, na mmanụ.
Ihe mkpuchi: Ethyl Cellulose na-enye mkpuchi mmiri, ike siri ike, mgbanwe na nnukwu gloss na agba na mkpuchi. Enwere ike iji ya na mkpuchi ụfọdụ ọpụrụiche dị ka akwụkwọ kọntaktị nri, ọkụ fluorescent, mkpuchi ụlọ, enamling, lacquers, varnishes, na mkpuchi mmiri.
Ceramics: A na-eji Ethyl Cellulose eme ihe nke ukwuu na seramiki emere maka ngwa eletrọnịkị dị ka seramiiki multi-layer capacitors. Ọ na-arụ ọrụ dị ka ihe nkedo na rheology modifier. Ọ na-enyekwa ike ndụ ndụ ma na-ere ọkụ na-enweghị ihe fọdụrụnụ.
Ink ibipụta: A na-eji Ethyl Cellulose na sistemu ink dabere na ihe mgbaze dị ka gravure, flexographic na ink mbipụta ihuenyo. Ọ bụ organosoluble na nke ukwuu dakọtara na plasticizers na polymers. Ọ na-enye mma rheology na njide Njirimara nke na-enyere guzobe ike dị elu na iguzogide ihe nkiri.
