Sodium carboxymethyl cellulose (CMC)

CMC bụ ngwaahịa a na-ejikarị na nke dabara adaba na cellulose ether, nke a na-akpọkarị "MSG ụlọ ọrụ".
CMC nwere ọtụtụ ihe dị mkpa e ji mara, dị ka akpụ elu viscosity colloid, ngwọta, nrapado, ndim, eruba, emulsification, dispersing, ịkpụzi, mmiri nchekwa, echebe colloid, film akpụ, acid iguzogide, nnu-eguzogide na turbidity na-eguzogide, na ọ dịghị njọ na physiology. .Ya mere, a na-eji CMC eme ihe n'ọtụtụ ebe na nri, ọgwụ, kemịkalụ kwa ụbọchị, mmanụ, ime akwụkwọ, textile, ihe owuwu na ubi ndị ọzọ.
(1) maka igwu mmiri na igwu mmanụ na gas, igwu olulu mmiri na ọrụ ndị ọzọ
① Apịtị nwere CMC nwere ike ime ka mgbidi olulu mmiri na-etolite achicha dị nro na nke siri ike na obere permeability, ma belata mmiri ozuzo.
② Mgbe agbakwunyere CMC n'ime apịtị ahụ, igwe na-egwupụta ihe nwere ike ịnweta ike mbido mbụ dị ala, mee ka apịtị ahụ dị mfe ịhapụ gas a na-etinye n'ime ya, ma tụfuo ihe mkpofu n'olulu apịtị ngwa ngwa.
③ Ngwuputa apịtị nwere oge ịdị adị, dị ka mgbasasị ndị ọzọ kwụsịtụrụ, CMC nwere ike mee ka ọ kwụsie ike ma gbatịa ya.
④ Mud nwere CMC anaghị emetụta ebu, n'ihi ya, ọ dịghị mkpa ịnọgide na-enwe nnukwu pH uru na nchekwa.
⑤ CMC na-eji dị ka ọgwụgwọ gị n'ụlọnga nke mkpọpu ala apịtị mmiri mmiri, nke nwere ike iguzogide mmetọ nke dị iche iche soluble salts.
⑥ The slurry na CMC nwere ezi kwụsie ike, na mmiri ọnwụ nwere ike belata ọbụna ma ọ bụrụ na okpomọkụ dị n'elu 150 ℃.
CMC nwere elu viscosity na elu nnọchi ogo kwesịrị ekwesị maka apịtị na ala njupụta na CMC na elu nnọchi ogo na ala viscosity kwesịrị ekwesị maka apịtị na elu njupụta.Ekwesịrị ịhọrọ CMC dabere na ụdị apịtị, mpaghara, omimi nke ọma na ọnọdụ ndị ọzọ.
(2) A na-eji CMC eme ihe dị ka onye na-emepụta ihe na akwa akwa na ụlọ ọrụ ibipụta na ịcha akwa, ma jiri ya mee ihe maka nha nke owu, ajị silk, eriri kemịkalụ, akwa ngwakọta na ihe ndị ọzọ siri ike;
(3) Enwere ike iji CMC mee ihe dị ka onye na-eji ire ụtọ na nha nha na ụlọ ọrụ akwụkwọ.Akwụkwọ ahụ nwere ike ịkwalite ike nkwụsị site na 40% - 50%, ogo mgbagwoju anya na-abawanye site na 50%, na ike igwakorita na-abawanye site na 4-5 ugboro site na-agbakwunye 0.1% na 0.3% CMC.
(4) Enwere ike iji CMC mee ihe dị ka ihe mgbasa ozi unyi mgbe a na-agbakwunye ya na ihe eji eme ihe;A na-eji kemịkalụ eme ihe kwa ụbọchị, dị ka glycerine aqueous solution of CMC na ụlọ ọrụ ntacha eze, na-eji dị ka isi gluu nke ntacha eze;A na-eji ụlọ ọrụ ọgwụ eme ihe dị ka thickener na emulsifier;CMC aqueous ngwọta na-eji dị ka flotation mgbe viscosity na-abawanye.
(5) enwere ike iji ya dị ka nrapado, plasticizer, onye nkwusioru na onye na-edozi ihe maka glaze na ụlọ ọrụ seramiiki.
(6) a na-eji ya eme ihe maka ụlọ iji meziwanye nchekwa na ike mmiri
