Ha ho tluoa ho solubility ea methyl cellulose, haholo-holo e bua ka ho qhibiliha ha sodium carboxymethyl cellulose.
Sodium carboxymethyl cellulose ke phofo e tšoeu kapa e mosehla ea flocculent, e sa nkheng ebile ha e latsoehe.E qhibiliha habonolo metsing a batang kapa a chesang, ho etsa tharollo e hlakileng ka viscosity e itseng.
Solubility ke eng?Ha e le hantle, e bolela boima ba solute e qhibilihisitsoeng ke ntho e itseng e tiileng sebakeng se batlang se tletse ka 100g ea solvent ka mocheso o itseng.Sena ke solubility.Ho qhibiliha ha methyl cellulose ho amana le likarolo tse peli.Ka lehlakoreng le leng, ho itšetlehile ka litšobotsi tsa carboxymethyl cellulose, 'me ka lehlakoreng le leng, e na le kamano e nyenyane le mocheso o ka ntle, mongobo, khatello, mofuta oa solvent, joalo-joalo The solubility ea carboxymethyl cellulose hangata ho totobetse hore e ameha ke mocheso, 'me o tla eketseha ka ho eketseha ha mocheso.
Ho na le mekhoa e meraro ea ho qhaqha methylcellulose:
1. Mokhoa oa ho kolobisa ka motsoako oa lintho tse phelang.Mokhoa ona ke haholo-holo ho qhalakanya kapa ho koloba li-solvents tsa MC tse kang ethanol le ethylene glycol esale pele, ebe o eketsa metsi ho qhala.
2. Mokhoa oa metsi a chesang.Hobane MC ha e qhibilihe metsing a chesang, MC e ka qhalakanngoa ka ho lekana metsing a chesang qalong.Ha ho pholile, ho ka sebelisoa mekhoa e 'meli e latelang:
(1) O ka qala ka ho eketsa tekanyo e loketseng ea metsi a chesang ka sejaneng ebe o se futhumatsa hoo e ka bang 70°C.MC e ile ea eketsoa butle-butle ka ho sisinyeha butle-butle, butle-butle ea etsa slurry, e ileng ea pholile ka ho sisinyeha.
(2) Eketsa 1/3 ea palo e hlokahalang ea metsi ka har'a setshelo se tsitsitseng, se futhumale ho 70 ° C, 'me u qhalakane MC ho latela mokhoa o sa tsoa boleloa, ebe o lokisa seretse sa metsi a chesang;ebe u e eketsa metsing a batang E ea ho slurry, hlohlelletsa hantle 'me u pholile motsoako.
3. Mokhoa oa ho kopanya phofo.Mokhoa ona ke haholo-holo ho qhala likaroloana tsa phofo tsa MC le metsoako e lekanang ea phofo ka ho kopanya ho omileng, ebe o eketsa metsi ho qhibiliha.
