Mgbe ọ na-abịa na solubility nke methyl cellulose, ọ bụ tumadi na-ezo aka solubility nke sodium carboxymethyl cellulose.
Sodium carboxymethyl cellulose bụ eriri na-acha ọcha ma ọ bụ na-acha odo odo, nke na-enweghị isi na enweghị ụtọ.Ọ dị mfe soluble na oyi ma ọ bụ mmiri ọkụ, na-akpụ a uzo ngwọta na ụfọdụ viscosity.
Gịnị bụ solubility?N'ezie, ọ na-ezo aka na uka nke solute etisasịwo site ụfọdụ siri ike umi na dịtụ jupụta ala na 100g nke ihe mgbaze na a ụfọdụ okpomọkụ.Nke a bụ solubility.Solubility nke methyl cellulose metụtara akụkụ abụọ.N'otu aka ahụ, ọ na-adabere n'àgwà nke carboxymethyl cellulose, na n'aka nke ọzọ, o nwere a obere mmekọrịta na mpụga okpomọkụ, iru mmiri, nrụgide, ihe mgbaze ụdị, wdg The solubility nke carboxymethyl cellulose na-emekarị kasị doro anya na-emetụta site na. okpomọkụ, ma ọ ga-abawanye na mmụba nke okpomọkụ.
E nwere ụzọ atọ nke igbari methylcellulose:
1. Organic mgbaze wetting usoro.Usoro a bụ tumadi ịkwasa ma ọ bụ mmiri mmiri MC organic solvents dị ka ethanol na ethylene glycol tupu oge eruo, wee tinye mmiri ka ọ gbazee.
2. Usoro mmiri ọkụ.N'ihi na MC bụ insoluble na mmiri ọkụ, MC nwere ike evenly agbasasị na mmiri ọkụ na mbụ ogbo.Mgbe ị na-ajụ oyi, enwere ike ịgbaso ụzọ abụọ ndị a:
(1) Ị nwere ike ibu ụzọ tinye mmiri ọkụ kwesịrị ekwesị n'ime akpa ahụ wee kpoo ya ihe dịka 70 Celsius.A na-eji nwayọọ nwayọọ gbakwunye MC na-akpali akpali, jiri nwayọọ nwayọọ na-emepụta slurry, nke a na-eme ka ọ dị mma site na mkpali.
(2) Tinye 1/3 nke mmiri achọrọ n'ime akpa a na-edozi, kpoo ya na 70 Celsius C, wee gbasaa MC dịka usoro a kpọtụrụ aha, wee dozie slurry mmiri ọkụ;wee tinye ya na mmiri oyi Gaa na slurry, kpalie nke ọma ma kpoo ngwakọta ahụ.
3. Usoro ngwakọta ntụ ntụ.Usoro a bụ tumadi iji chụsasịa MC ntụ ntụ na nha nha ntụ ntụ site na ịgwakọta akọrọ, wee tinye mmiri ka ọ gbazee.
