Ethylcellulose bụ polymer bara ụba nwere ngwa na ụlọ ọrụ dị iche iche, gụnyere ọgwụ, mkpuchi, nrapado na nri. A na-ahazi ọkwa dị iche iche nke ethylcellulose iji mezuo ihe a chọrọ n'ihe gbasara viscosity, arọ molecular na ihe ndị ọzọ.
Ọdịdị ethyl cellulose:
Ethylcellulose bụ ihe sitere na cellulose, polymer eke dị na mgbidi sel osisi. Ethylation nke cellulose gụnyere iwebata otu ethyl n'ime ọrụ hydroxyl (-OH) nke cellulose. Mgbanwe a na-enye ethylcellulose ihe pụrụ iche, na-eme ka ọ sie ike na ihe mgbaze organic ma na-enye ikike imepụta ihe nkiri mara mma.
Njirimara nke ethylcellulose:
Solubility: Ethylcellulose bụ soluble n'ọtụtụ ihe mgbaze organic, dị ka alcohols, ketones, esters, wdg.
Ihe ndị na-emepụta ihe nkiri: Ihe ndị na-emepụta ihe nkiri mara mma, nke kwesịrị ekwesị maka mkpuchi na ihe nkiri.
Thermoplasticity: Ethylcellulose na-egosipụta omume thermoplastic, na-ekwe ka a kpụzie ya ma ọ bụ guzobe ya mgbe ọ na-ekpo ọkụ.
Inert: Ọ bụ kemịkalụ inert, na-enye nkwụsi ike na ngwa dị iche iche.
Ọkwa ethylcellulose:
1. Ọkwa viscosity dị ala:
Akara ule ndị a nwere arọ molekụla dị ala ya mere viscosity dị ala.
Kwesịrị ekwesị maka ngwa chọrọ mkpuchi ma ọ bụ ihe nkiri dị mkpa.
Ọmụmaatụ gụnyere usoro ntọhapụ ọgwụ na-achịkwa yana mkpuchi dị mkpa na mbadamba.
2. Ọkara viscosity dị ọkara:
Ọkara molekụla arọ na viscosity.
A na-eji ya n'ọtụtụ ebe na ụlọ ọrụ na-emepụta ọgwụ maka nhazi mwepụta na-adịgide adịgide, ebe nguzozi n'etiti ọkpụrụkpụ mkpuchi na ọnụego ntọhapụ dị oke egwu.
A na-ejikwa ya na mmepụta nke adhesives pụrụ iche na sealants.
3. Ọkwa viscosity dị elu:
Akara ule ndị a nwere ibu molekụla dị elu ya mere viscosities dị elu.
Kwesịrị ekwesị maka ngwa chọrọ akwa mkpuchi ma ọ bụ ihe nkiri.
Ejiri ya na mmepụta ihe mkpuchi nchebe dị ka inks, agba na varnish.
4. Ọkwa dị mma:
Ndị a akara ule nwere nta urughuru nha, nke na-enyere aka mee ka mkpuchi smoother na melite mgbasa na ngwọta.
Chọta ngwa maka ink obibi akwụkwọ dị elu na mkpuchi maka ịkwado ọmarịcha elu.
5. Ọdịnaya ọdịnaya ethoxy dị elu:
Ethylcellulose nwere ogo ethoxylation dị elu.
Na-enye nkwalite solubility n'ọtụtụ ihe mgbaze.
Ejiri ya na ngwa chọrọ polymers solubility dị elu, dị ka ụfọdụ usoro ọgwụ.
6. Ọkwa ọdịnaya dị ala:
Ethyl cellulose nwere obere mmiri ọdịnaya.
Kwesịrị ekwesị maka ngwa ebe mmetụta mmiri dị na-eche, dị ka mmepụta nke ọgwụ na-ahụ maka mmiri.
7. Thermoplastic akara ule:
Akara ule ndị a na-egosipụta omume thermoplastic emelitere.
A na-eji ngwa ịkpụzi ebe ọ dị mkpa ka eme ka ihe dị nro na ịkpụzi ya na oke okpomọkụ.
8. Ọkwa ntọhapụ a na-achịkwa:
Ezubere maka usoro ọgwụ na-achọ ntọhapụ ọgwụ na-achịkwa ogologo oge.
Haziri iji nweta kinetics ntọhapụ chọrọ ka ọ na-ejigide nkwụsi ike.
Ngwa nke ethylcellulose:
1. Ọgwụ:
Nkwadebe ọgwụ ntọhapụ a na-achịkwa.
Mbadamba ụrọ mkpuchi maka uto masking na mgbasa a na-achịkwa.
Ihe nkedo maka granules n'ichepụta mbadamba nkume.
2. Mkpuchi na ink:
Ihe mkpuchi mkpuchi maka elu dị iche iche.
Ink na-ebi akwụkwọ maka flexographic na gravure obibi.
Ihe mkpuchi ụgbọ ala na ụlọ ọrụ mmepụta ihe.
3. Adhesives na sealants:
Adhesives pụrụ iche maka ngwa dị iche iche.
Sealants eji maka nkwonkwo na akara na-ewu na n'ichepụta.
4. Ụlọ ọrụ nri:
Mkpuchi oriri na mkpụrụ osisi na akwụkwọ nri na-agbatị ndụ ndụ.
Encapsulation nke flavors na fragrances.
5. Plastics na ịkpụzi:
Thermoplastic omume na ịkpụzi ngwa.
Na-emepụta ngwaahịa rọba pụrụ iche.
6. Ngwa eletrọnịkị:
A na-eji na-emepụta ihe mkpuchi nchebe maka ihe ndị dị na kọmputa.
na ngwụcha:
Ọkwa ethylcellulose dị iche iche dị iji zute ngwa dị iche iche na ụlọ ọrụ dị iche iche. Site na ọgwụ ruo na mkpuchi na nrapado, ntụgharị ethylcellulose dị na akara ule ya dị iche iche, nke ọ bụla emere iji gboo mkpa ụfọdụ. Ka teknụzụ na ihe ndị ụlọ ọrụ chọrọ na-aga n'ihu na-aga n'ihu, mmepe nke akara ule ethylcellulose ọhụrụ nwere akụrụngwa emelitere nwere ike rụọ ọrụ dị mkpa n'igbo mkpa nke ngwa na-apụta. Ịghọta ọdịiche dị n'etiti akara ule ndị a na-enyere ndị na-emepụta aka ịhọrọ ethylcellulose kachasị mma maka ngwa ha kpọmkwem, na-eme ka arụmọrụ na arụmọrụ dị mma.
