Hydroxyethyl cellulose (HEC) polymer ne mai narkewa da ruwa wanda galibi ana amfani dashi a aikace-aikace daban-daban kamar su adhesives, sutura, da samfuran kulawa na sirri. Narkar da HEC a cikin ruwa tsari ne mai sauƙi wanda za'a iya cika ta amfani da matakai masu zuwa:
Zaɓi madaidaicin sa na HEC: HEC yana samuwa a cikin nau'o'i daban-daban tare da ma'aunin kwayoyin halitta daban-daban da digiri na maye gurbin. Zaɓin darajar zai dogara ne akan takamaiman aikace-aikacen da abubuwan da ake so na samfurin ƙarshe.
Shirya ruwan: Mataki na farko shine shirya ruwan ta hanyar auna yawan ruwan da ake buƙata da dumama shi zuwa zafin jiki tsakanin 70-80 ° C. Dumama ruwan zai taimaka wajen hanzarta aikin rushewa da kuma tabbatar da cewa HEC ta cika ruwa.
Ƙara HEC zuwa ruwa: Da zarar ruwan ya kai yawan zafin jiki da ake so, a hankali ƙara HEC zuwa ruwa yayin da yake motsawa akai-akai. Yana da mahimmanci don ƙara HEC a hankali kuma a hankali don kauce wa raguwa da kuma tabbatar da cewa an tarwatsa shi sosai a cikin ruwa.
Ci gaba da motsawa: Bayan ƙara HEC zuwa ruwa, ci gaba da motsa cakuda don kimanin minti 30. Wannan zai taimaka wajen tabbatar da cewa HEC ta narkar da shi da ruwa.
Bada cakuda don kwantar da hankali: Bayan HEC ya narkar da shi sosai, ba da damar cakuda ya yi sanyi zuwa zafin jiki. Yayin da cakuda ya yi sanyi, zai yi kauri kuma ya kai ga ɗanƙoƙinsa na ƙarshe.
Daidaita pH da danko: Dangane da takamaiman aikace-aikacen, yana iya zama dole don daidaita pH da danko na maganin HEC. Ana iya yin wannan ta ƙara acid ko tushe don daidaita pH kuma ta ƙara ruwa ko ƙarin HEC don daidaita danko.
narkar da HEC a cikin ruwa tsari ne mai sauƙi wanda za'a iya cika tare da wasu matakai na asali. Ta hanyar zabar ma'auni na HEC mai kyau, shirya ruwa yadda ya kamata, da kuma motsa cakuda a ci gaba, yana yiwuwa a sami cikakken narkar da maganin HEC wanda za'a iya amfani dashi a aikace-aikace iri-iri.
