2. Ukuthuthukiswa kokusebenza okungakhethwa

Uchungechunge lwe-Cellulose ether HE, okungukuthi, i-hydroxyethyl cellulose, iyimpushana emhlophe ukuya ku-milky. Ingancibilika emanzini ashisayo nasemanzini abandayo, kodwa akulula ukuncibilika kuma-organic solvents. Imikhiqizo yochungechunge lwe-Jinshi brand cellulose ether HE inokugcinwa kwamanzi okuqinile, ukwakheka kwefilimu, ukumelana nosawoti kanye nemiphumela yokuqina. Iphinde ibe nokuhambisana kahle kombala futhi iyisengezo esifanelekile ezinhlelweni ze-latex.

IHydroxyethyl cellulose HEC iwugqinsi osetshenziswa kakhulu embotsheni futhi inezinzuzo ezilandelayo:

(1) Ukusebenza ngezindlela ezihlukahlukene okunamandla I-Hydroxyethyl cellulose HEC iyi-polymer engancibiliki emanzini engeyona i-ionic engasetshenziswa kububanzi be-pH ebanzi (2-12). Ingaxutshwa nezingxenye ekugqokeni okujwayelekile (okufana nezingulube, izithasiselo, usawoti oncibilikayo nama-electrolyte) ngaphandle kwezimo ezingavamile. i

(2) Ukwakhiwa okuhle. I-coating egqinsiwe nge-hydroxyethyl cellulose HEC ine-pseudoplasticity, ngakho-ke ingasetshenziswa ngokuxubha, ngokufafaza, i-roller coating nezinye izindlela zokwakha. Izinzuzo, ukulinganisa nakho kungcono. i

(3) Awukho umthelela omubi kwifilimu yokumboza. Ngenxa yezimpawu zokungezwani kwamanzi okungabonakali kwesisombululo esinamanzi se-HEC, akulula ukukhipha igwebu ngesikhathi sokwakhiwa nokukhiqizwa, futhi kuncane ukuthambekela kokukhiqiza izimbobo zentaba-mlilo namaphinifa. i

(4) Ukuthuthukiswa kombala okuhle. I-Hydroxyethyl cellulose HEC ine-miscibility enhle kakhulu enezibophezelo eziningi nemibala, ukuze upende olungisiwe ube nokusimama okuhle kombala nokuvumelana.

(5) Ukuzinza okuhle kwesitoreji. Ngesikhathi sokugcinwa kopende, kungagcina ukumiswa kanye nokuhlakazeka kwe-pigment, ngaphandle kwezinkinga zokuntanta nokuqhakaza. Kukhona ungqimba lwamanzi oluncane phezu kopende. Lapho izinga lokushisa lokugcina lishintsha, i-viscosity yayo ihlala ifana. ezinzile.
