Nkọwa ngwaahịa:
Carboxymethyl Cellulose (CMC) (nke a na-akpọkwa cellulose chịngọm) bụ ihe anaonic linear polymer structure cellulose ether. Ọ na-acha ọcha ma ọ bụ ubé odo ntụ ntụ ma ọ bụ granules, enweghị ụtọ na-adịghị egbu egbu, arụ ọrụ kwụsiri ike. Ọ nwere ike soluble na mmiri na-etolite a uzo ngwọta na ụfọdụ viscosity. Ngwọta ya na-anọpụ iche ma ọ bụ obere alkaline, ma kwụsie ike na ìhè na okpomọkụ. E wezụga nke ahụ, viscosity ga-ebelata na okpomọkụ na-abawanye.
Ngwa:
Ịgbapu mmanụ. CMC na-arụ ọrụ nke mmiri na-efunahụ, mmụba viscosity na mmiri mmiri na-egwupụta mmiri, mmiri cimenting na mmiri na-agbaji, iji chebe mgbidi ahụ, na-ebu osisi, chebe ihe ọkụkụ ahụ, gbochie ụrọ apịtị, ma melite ngwa ngwa.
Ụlọ ọrụ akwa, mbipụta na ịcha akwa. A na-eji CMC dị ka onye na-emepụta ihe maka nha nke yarn ọkụ dị ka owu, ajị silk, eriri kemịkal, na ngwakọta.
Ụlọ ọrụ akwụkwọ. Enwere ike iji ya dị ka ihe na-eme ka ọ dị nro n'elu akwụkwọ na onye na-ahụ maka nha. Dị ka ihe mgbakwunye, CMC nwere ihe ndị na-emepụta ihe nkiri na nguzogide mmanụ nke polymers mmiri soluble.
CMC-ọkwa. CMC nwere ogo dị elu nke ịdị n'otu na nghọta dị mma na ncha. Ọ nwere ezigbo dispersibility na mmiri na ezigbo ọrụ mgbochi resorption. Ọ nwere ọtụtụ àgwà dị ka ultra-elu viscosity, ezi nkwụsi ike, magburu onwe ndim na emulsifying mmetụta.
Ihe osise CMC. Dị ka ihe nkwụsi ike, ọ nwere ike igbochi mkpuchi nkewa n'ihi mgbanwe okpomọkụ ngwa ngwa. Dị ka a viscosity gị n'ụlọnga, ọ nwere ike ime ka mkpuchi ala edo, nke mere iji nweta ezigbo nchekwa na ewu viscosity, na-egbochi oké njọ delamination n'oge nchekwa.
Ọkwa CMC nke anwụnta na-egbochi ihe nsure ọkụ. CMC nwere ike jikọta ihe ndị ahụ ọnụ. Ọ nwere ike ime ka ihe nsure ọkụ na-esi ísì ụtọ nke anwụnta na-esi ike, na-eme ka ọ ghara ịdị mfe ịgbaji.
Ọkwa ntacha eze nke CMC. A na-eji CMC eme ihe dị ka gluu na nsí eze. Ọ tumadi na-arụ ọrụ nke ịkpụzi na adhesion.CMC nwere ike igbochi nkewa nke abrasive na-eme ka agbanwe agbanwe uwe maka ịnọgide na-enwe ike mado ala.
Ụlọ ọrụ seramiiki. Enwere ike iji ya dị ka nrapado oghere, plasticizer, onye na-egbochi glaze, onye na-edozi agba, wdg.
Ụlọ ọrụ ụlọ. Ejiri ya rụọ ọrụ, ọ nwere ike melite njigide mmiri na ike nke ngwa agha.
Ụlọ ọrụ nri. Carboxymethyl cellulose na nri nwere ike iji dị ka thickener, stabilizer, nrapado ma ọ bụ udi onye nnọchite anya.
