Site n'ịgbanwe ọnọdụ mmeghachi omume, enwere ike ịchịkwa ogo nke nnọchi hydroxyethyl, si otú a na-edozi solubility mmiri, viscosity na ihe ndị ọzọ anụ ahụ nke HEC.
2. Njirimara anụ ahụ na kemịkal nke hydroxyethyl cellulose
Ntuziaka viscosity: Hydroxyethyl cellulose bụ ihe na-eme ka ọ dị mma ma na-ejikarị eme ihe iji dozie viscosity nke mmiri mmiri. Ya ngwọta viscosity na-adabere solubility ịta, ogo nke polymerization na ogo nke nnọchi, ya mere, ya rheological Njirimara nwere ike ịchịkwa site n'ịgbanwe molekul arọ;
Ọrụ dị n'elu: Ebe ọ bụ na mkpụrụ ndụ HEC nwere ọnụ ọgụgụ dị ukwuu nke hydroxyl dị iche iche, ha nwere ike ịmepụta ihe nkiri molecular na interface ahụ, na-arụ ọrụ nke surfactant, ma nyere aka mee ka emulsions na usoro nkwụsịtụ kwụsị;
Ngwongwo na-emepụta ihe nkiri: Hydroxyethyl cellulose nwere ike ịmepụta ihe nkiri otu mgbe ọ nwụsịrị, ya mere a na-eji ya eme ihe na ihe ịchọ mma, mkpuchi ọgwụ na mpaghara ndị ọzọ;
Njide mmiri: Hydroxyethyl cellulose nwere ezigbo hydration, nwere ike ịmịkọrọ ma na-ejigide mmiri, ma na-enyere aka ịgbatị oge mmiri mmiri nke ngwaahịa ahụ.
3. Mpaghara ngwa
Mkpuchi na ihe owuwu ụlọ: HEC bụ ihe na-esi ísì ụtọ na-ejikarị eme ihe na ụlọ ọrụ mkpuchi. Ọ nwere ike melite rheology nke mkpuchi ahụ, mee ka mkpuchi ahụ dịkwuo mma, ma zere ịkwa ụda. N'ime ihe owuwu ụlọ, a na-eji ciment ciment, gypsum, putty powder, wdg, na-eme ka arụ ọrụ ụlọ dịkwuo mma, na-eme ka njigide mmiri dịkwuo elu ma melite nkwụsị mgbawa.
Kemịkalụ kwa ụbọchị: Na ịchọ mma na ngwaahịa nlekọta onwe onye, a na-ejikarị HEC na ncha ntutu, gel ịsa ahụ, ude mmiri na ngwaahịa ndị ọzọ iji nye nkwusioru na nkwusioru nkwusioru, na-eme ka mmetụta moisturize dịkwuo mma.
Ụlọ ọrụ nri: Ọ bụ ezie na a na-ejikarị HEC eme ihe na nri, a pụrụ iji ya mee ihe dị ka ihe na-eme ka ọ dị arọ na ihe nkwụsịtụ na ụfọdụ nri ụfọdụ dị ka ice cream na condiments.
Ebe ahụike: A na-ejikarị HEC eme ihe dị ka thickener na matrix maka capsules na nkwadebe ọgwụ, karịsịa na ọgwụ ophthalmic maka imepụta anya mmiri artificial.
Ụlọ ọrụ na-emepụta akwụkwọ: A na-eji HEC mee ihe dị ka ihe na-eme ka akwụkwọ, ihe na-eme ka ọ dị nro na mkpuchi mkpuchi na ụlọ ọrụ na-emepụta akwụkwọ.
4. Uru nke hydroxyethyl cellulose
Ezigbo solubility: HEC dị mfe soluble na mmiri ma nwee ike ịmepụta ngwọta viscous ngwa ngwa.
Mgbanwe ngwa ngwa: HEC dabara maka mgbasa ozi dị iche iche na gburugburu pH.
Nkwụsi ike nke kemịkalụ dị mma: HEC na-akwụsi ike n'ọtụtụ ihe mgbaze na okpomọkụ ma nwee ike ịnọgide na-arụ ọrụ ya ogologo oge.
5. Ahụike na nchekwa nke hydroxyethyl cellulose
A na-ewerekarị Hydroxyethyl cellulose dị ka ihe na-adịghị emerụ ahụ mmadụ. Ọ naghị egbu egbu ma ọ dịghị akpasu akpụkpọ ahụ ma ọ bụ anya iwe, ya mere a na-eji ya eme ihe n'ọtụtụ ebe na ihe ịchọ mma na ọgwụ. Na gburugburu ebe obibi, HEC nwekwara ezigbo biodegradability na anaghị akpata mmetọ gburugburu ebe obibi.
Hydroxyethyl cellulose nọchitere anya CAS No. 9004-62-0 bụ ihe multifunctional polymer nwere ọmarịcha arụmọrụ. N'ihi nkwụsi ike ya, nkwụsi ike, imepụta ihe nkiri, mmiri na-ekpo ọkụ na ihe ndị ọzọ, a na-ejikarị ya eme ihe n'akụkụ dị iche iche nke mmepụta mmepụta ihe na ndụ kwa ụbọchị.
