Ethyl cellulose (EC)bụ ihe dị mkpa nke cellulose ether na-abụghị ionic nke nwere uru teknụzụ a na-apụghị ịgbanwe agbanwe na sistemụ mgbasa colloidal n'ihi njirimara ya dị mma nke na-emepụta fim, hydrophobicity, na nkwụsi ike.
1. Imeziwanye Nkwụsi Ike nke Sistemụ Mgbasa nke Colloidal
Uru teknụzụ kachasị ukwuu nke EC dị n'ike ya imeziwanye nkwụsi ike sistemụ. N'ihi mgbanwe na ihe ndị na-abanye n'ime agbụ molekul EC, ọ nwere ike ịmepụta oyi akwa nchebe steric n'elu ihe ndị ahụ, na-egbochi nchịkọta na sedimentation nke ọma. Ọzọkwa, ọdịdị na-abụghị ionic nke EC na-enye ya ohere ịnọgide na-eguzosi ike n'okpuru ọnọdụ pH dị iche iche, na-egbochi mmiri ozuzo n'ihi mgbanwe na acidity sistemụ ma ọ bụ alkalinity, nke na-enye ọtụtụ ojiji maka sistemụ nhazi dị mgbagwoju anya.
Maka ihe mkpuchi, ihe mkpuchi seramiiki, ma ọ bụ sistemụ mgbasa ọdịnaya siri ike nke nwere agba na ihe njupụta na-adịghị mma, EC nwekwara ike ibelata ugboro ole ihe na-akpata nsụkọta ihe ma gbasaa oge nkwụsi ike nke ọnọdụ agbasasị. Ike a na-enyere aka nke ukwuu n'ịnọgide na-adị ndụ nchekwa ma zere ịgbasa ọzọ tupu e tinye ya.
2. Ịhazi Njirimara Rheological nke Sistemụ ahụ
EC na-egosipụta ezigbo ihe ndị dị mkpa maka ịgbasa, nhazi, na njikwa, nke enwere ike iji melite usoro rheological nke sistemụ colloidal. N'okpuru ọnọdụ ịgbasa obere, EC na-eme ka usoro ahụ dịkwuo mma ma na-eme ka nhazi ya dịkwuo mma, si otú a na-ebelata nhazi na nhazi. N'okpuru ọnọdụ ịgbasa elu, agbụ molekul ya na-ekewa ma na-eme ka ọ dị jụụ, na-enye sistemụ ahụ ezigbo ihe ndị na-eme ka ọ dị gịrịgịrị, nke bara uru maka itinye ya, ịgbasa ya, na ịgbasa ya.
Njirimara a nke "mkpụcha dị ala, nke na-agba ọsọ dị elu" na-eme ka EC dabara adaba karịsịa maka mkpuchi ụlọ, ink mbipụta, ngwaahịa mado, na sistemụ mgbasa nke nwere nnukwu njupụta, na-eme ka sistemụ kwụsie ike na arụmọrụ dịkwuo mma n'enweghị mmetụta nhazi.
3. Ime ka nhazi ihe nkiri na ihe ndị e ji arụ ọrụ dịkwuo mma
Njirimara hydrophobicity na nhazi ihe nkiri nke EC na-eme ka ọ bụrụ ihe mgbakwunye dị mma maka imepụta ihe nkiri na sistemụ mgbasa nke colloidal. N'ime sistemụ mmiri, ọ bụ ezie na EC anaghị agbaze na mmiri, enwere ike ịgbasa ya n'otu oge na ọnọdụ colloidal, n'oge usoro nkụcha, ejikọtara ya na ihe ndị ọzọ na-emepụta ihe nkiri iji mepụta ihe nkiri dị oke arọ ma na-agbanwe agbanwe.
Ihe nkiri a nwere ezigbo iguzogide mmiri, iguzogide ihe mgbaze, na iguzogide ihu igwe, na-eme ka ike, iguzogide iyi, na ihe mgbochi nke mkpuchi ahụ ka mma nke ukwuu. Ya mere, a na-eji EC eme ihe nke ukwuu na:
Mkpuchi na sistemụ ink
Ngwakọta
Ihe nkiri nchekwa
Ihe mkpuchi seramiiki na ihe njikọta okpomọkụ dị elu
iji melite arụmọrụ nke ihe nkiri ikpeazụ.
4. Imeziwanye ike plastik na nhazi
Na sistemụ colloidal, EC nwere ike ịrụ ọrụ dị ka ihe na-agbanwe agbanwe, na-eme ka ike na mgbochi mgbawa nke ihe ndị dị na ya dịkwuo mma, na-eme ka ha ghara ịgbawa agbawa mgbe a na-akpọ nkụ ma ọ bụ na-agwọ ha. Ịtinye EC na ngwa agha ụlọ, ihe ndị e ji seramiiki mee, na ihe ndị e ji mado mee nwere ike:
Mee ka ike mmiri na thixotropy dịkwuo elu
Melite mgbasa na mkpuchi
Mee ka iguzogide ịdaba na steeti a kpụrụ akpụ dịkwuo mma
N'ụlọ ọrụ ọgwụ, a na-eji EC eme ihe dị ka ihe a na-achịkwa maka mkpuchi kapsụl na mkpuchi ihe ndị dị n'ime ya, na-egbu oge mwepụta nke ihe ndị na-arụ ọrụ.
5. Ime ka mmiri ghara iguzogide mmiri na nguzozi mmiri ghara ịdị mma
EC bụ otu n'ime ụdị cellulose ethers kachasị emerụ ahụ. Njirimara nhazi a na-enye ya ohere ịgbanwe nguzozi hydrophilic-hydrophobic nke sistemu colloidal. Na gel mmiri, mkpuchi, ma ọ bụ sistemu mado, oke EC kwesịrị ekwesị nwere ike ime ka iguzogide mmiri na ọzịza dịkwuo mma, na-enye ohere ka ngwaahịa ikpeazụ nọgide na-adị mma na gburugburu ebe mmiri dị.
Mmetụta ya dị oke mkpa maka ojiji n'ebe mmiri dị oke elu, dịka mkpuchi mgbidi mpụta, ihe nrapado ebe mmiri dị, ma ọ bụ sistemụ colloidal nwere oge nchekwa ogologo.
Uru nkeECna sistemụ mgbasa nke colloidal, a na-egosipụtakarị ya n'akụkụ dịka mgbasa siri ike, rheology ka mma, nhazi ihe nkiri ka mma, iguzogide mmiri ka mma, na arụmọrụ nhazi ka mma. O nwere ma nchekwa nke ihe polymer eke na ọrụ dị elu nke ihe mgbakwunye sịntetik, na-eme ka ọ nọgide na-arụ ọrụ dị mkpa na ụlọ ọrụ owuwu, ink, seramiiki, nri, na ụlọ ọrụ ọgwụ.
