Ịghọta Njirimara Kemịkalụ nke Ethyl Cellulose

Ethyl cellulose bụ polima nwere ọtụtụ ọrụ dị iche iche n'ọtụtụ ụlọ ọrụ dịka ọgwụ, nri, mkpuchi, na nlekọta onwe onye. Ịghọta njirimara kemịkalụ ya dị oke mkpa maka iji ike ya mee ihe n'ọtụtụ usoro na usoro dị iche iche.

Nhazi Kemịkalụ:

Ethyl cellulose sitere na cellulose, polima eke a na-ahụ n'ime osisi. Site na mgbanwe kemịkalụ, a na-ewebata otu ethyl n'ime azụ cellulose, na-ebute mmepụta ethyl cellulose. Enwere ike igosi nhazi kemịkalụ nke ethyl cellulose dị ka ndị a:

Cellulose+Ethyl Otu →Ethyl Cellulose Otu Cellulose+Ethyl→Ethyl Cellulose

Mmiri iyi mmiri:

Otu n'ime ihe ndị bụ isi dị na kemịkalụ nke ethyl cellulose bụ ọdịdị hydrophobic ya. Ntinye nke otu ethyl n'ime ọkpụkpụ azụ cellulose na-ebelata polarity nke polymer, na-ebute mbelata mmasị maka mmiri. Hydrophobicity a na-eme ka ethyl cellulose ghara ịgbaze na mmiri mana ọ na-agbaze na ihe mgbaze organic dịka ethanol, toluene, na chloroform.

Ọdịdị okpomọkụ:

Ethyl cellulose na-egosipụta àgwà thermoplastic, nke pụtara na ọ na-eme ka ọ dị nro ma sie ike mgbe a jụrụ ya oyi na-enweghị mmebi kemịkalụ. Ihe onwunwe a na-eme ka ethyl cellulose dabara adaba maka ụzọ nhazi dị iche iche dịka ịpụpụ, ịkpụzi ihe, na ịtụ ihe nkiri. Ọdịdị thermoplastic nke ethyl cellulose na-enye ohere maka mmepụta nke ihe nkiri, mkpuchi, na ihe ndị a kpụrụ akpụ nwere ihe ndị a na-achọsi ike.

Njirimara Ịme Ihe Nkiri:

Mgbe a gbazere ya na ihe ndị na-agbaze ihe ndị dị ndụ kwesịrị ekwesị, ethyl cellulose nwere ike ịmepụta ihe nkiri doro anya, na-agbanwe agbanwe, ma na-apụta ìhè mgbe ihe mgbaze ahụ gbazere. Ihe nkiri ndị a nwere ihe mgbochi dị mma megide mmiri mmiri, gas, na mmanụ, na-eme ka ha dị mma maka iji ha mee ihe na mkpuchi, mkpuchi, na ngwa nkwakọ ngwaahịa.

Ndakọrịta:

Ethyl cellulose dakọtara na ọtụtụ polima ndị ọzọ, ihe ndị na-eme ka plastik dị, na ihe mgbakwunye, na-enye ohere maka imepụta ngwakọta ahaziri ahazi yana ihe ndị pụrụ iche. Enwere ike ijikọ ya na polima ndị ọzọ dịka polyvinyl acetate (PVA), resin acrylic, ma ọ bụ ihe ndị sitere na cellulose iji nweta njirimara arụmọrụ achọrọ na mkpuchi, ihe nrapado, na matrices maka nnyefe ọgwụ a na-achịkwa.

Nkwụsi Ike Kemịkalụ:

Ethyl cellulose na-egosipụta ezigbo nkwụsi ike kemịkalụ, na-eguzogide mmebi site na ikpughe ìhè, okpomọkụ, na oxygen. Nkwụsi ike a na-eme ka ngwaahịa nwere ethyl cellulose rụọ ọrụ ogologo oge, ọkachasị n'ọrụ ebe ịdịte aka na ndụ nchekwa dị oke mkpa, dịka mbadamba ọgwụ na mkpuchi.

Mmechi:

Na mmechi, ethyl cellulose nwere ọtụtụ ihe kemịkalụ dị mkpa nke na-eme ka ọ bụrụ polima bara uru n'ọtụtụ ụlọ ọrụ. Mmiri ya na-ekpo ọkụ, okpomọkụ ya, ihe ndị na-emepụta ihe nkiri, ndakọrịta ya, na nkwụsi ike kemịkalụ na-eme ka ojiji ya dị iche iche, gụnyere ọgwụ, nri, mkpuchi, na nlekọta onwe onye. Ịghọta ihe kemịkalụ ndị a dị mkpa maka ime ka arụmọrụ na ịdị irè nke ihe mejupụtara nwere ethyl cellulose dịkwuo mma, na-eduga na mmepe nke ngwaahịa ọhụrụ nwere ihe onwunwe na ọrụ achọrọ.
