Carboxymethyl ethoxy ethyl cellulose
Carboxymethyl ethoxy ethyl cellulose (CMEEC) bụ cellulose ether ether emezigharịrị eji eme ihe n'ụlọ ọrụ dị iche iche maka ịgbatị ya, nkwụsi ike, imepụta ihe nkiri, yana ihe njigide mmiri. A na-emepụta ya site n'ịgbanwe cellulose na kemịkal site na mmeghachi omume na-aga n'ihu gụnyere ethoxylation, carboxymethylation, na ethyl esterification. Nke a bụ nkọwa nkenke nke CMEEC:
Njirimara ndị bụ isi:
- Ọdịdị kemịkalụ: CMEEC sitere na cellulose, polymer eke sitere na nkeji glucose. Mgbanwe a gụnyere iwebata otu ethoxy (-C2H5O) na carboxymethyl (-CH2COOH) n'ime ọkpụkpụ azụ cellulose.
- Otu dị iche iche na-arụ ọrụ: Ọnụnọ nke ethoxy, carboxymethyl, na ethyl ester otu na-enye CMEEC ihe pụrụ iche, gụnyere solubility na mmiri na ihe mgbaze organic, ikike imepụta ihe nkiri, yana omume ịgbado pH dabere.
- Mmiri Solubility: CMEEC bụ a soluble na mmiri, akpụ viscous ngwọta ma ọ bụ dispersions dabere ya ịta na pH nke ọkara. Otu carboxymethyl na-enye aka na mmiri solubility nke CMEEC.
- Ikike imepụta ihe nkiri: CMEEC nwere ike ịmepụta ihe nkiri doro anya, na-agbanwe agbanwe mgbe akpọnwụwo, na-eme ka ọ baa uru na ngwa ndị dị ka mkpuchi, nrapado, na ngwaahịa nlekọta onwe onye.
- Thickening na Rheological Properties: CMEEC na-arụ ọrụ dị ka onye na-eme ihe na-ekpo ọkụ na ngwọta mmiri, na-amụba viscosity ma na-eme ka nkwụsi ike na nhazi nke nhazi. Ihe ndị dị ka itinye uche, pH, okpomọkụ, na ọnụ ọgụgụ nke shiee nwere ike imetụta àgwà ya na-eme ka ike sie ike.
Ngwa:
- Mkpuchi na agba: A na-eji CMEEC mee ihe dị ka ihe na-agbapụta, ihe nkedo, na onye na-emepụta ihe nkiri na ihe mkpuchi na agba nke mmiri. Ọ na-eme ka ihe ndị na-ahụ maka rheological dịkwuo mma, nhazi ọkwa, na adhesion nke mkpuchi mgbe ọ na-enye ihe nkiri iguzosi ike n'ezi ihe na ogologo oge.
- Adhesives na Sealants: A na-etinye CMEEC n'ime ihe nrapado na ihe mkpuchi iji meziwanye tackiness, nrapanye, na ịdị n'otu. Ọ na-enye aka na viscosity, ịrụ ọrụ, na ike njikọ nke adhesives na sealants.
- Ngwaahịa Nlekọta Onwe Onye: A na-eji CMEEC eme ihe na ịchọ mma, ụlọ mposi, yana ngwaahịa nlekọta onwe onye dị ka ude, lotions, gels, na usoro nlekọta ntutu. Ọ na-arụ ọrụ dị ka thickener, stabilizer, emulsifier, na onye na-emepụta ihe nkiri, na-eme ka udidi ngwaahịa na-eme ka ọ dịkwuo mma, na-agbasawanye na moisturize.
- Pharmaceuticals: CMEEC na-achọta ngwa n'ụdị usoro ọgwụ dị ka nkwusioru ọnụ, ude dị n'elu, na ụdị ntọhapụ na-achịkwa. Ọ na-eje ozi dị ka ihe nkedo, viscosity modifier, na ihe nkiri mbụ, na-eme ka nnyefe ọgwụ na nkwụsi ike ụdị usoro onunu ogwu.
- Ngwa ụlọ ọrụ na ngwa ọpụrụiche: Enwere ike iji CMEEC na ngwa ụlọ ọrụ dị iche iche, gụnyere akwa akwa, mkpuchi akwụkwọ, ihe owuwu na ngwaahịa ugbo, ebe njiri ya, njide, na imepụta ihe nkiri bara uru.
carboxymethyl ethoxy ethyl cellulose (CMEEC) bụ ihe nrụpụta cellulose dị iche iche nwere ngwa dị iche iche na mkpuchi, adhesives, ngwaahịa nlekọta onwe onye, ọgwụ na mpaghara ụlọ ọrụ ndị ọzọ, n'ihi ike mmiri ya, ikike imepụta ihe nkiri na akụrụngwa rheological.
