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.
