Cellulose ether HE series, ke hore, hydroxyethyl cellulose, ke phofo e tšoeu ho isa ho lebese. E ka qhibiliha ka metsing a chesang le a batang ka bobeli, empa ha ho bonolo ho qhibiliha ka har'a metsoako ea tlhaho. Jinshi brand cellulose ether HE lihlahisoa tsa lihlooho li na le ho boloka metsi a matla, ho etsa filimi, ho hanyetsa letsoai le liphello tse teteaneng. E boetse e na le tšebelisano e ntle ea mebala ebile ke tlatsetso e loketseng lits'ebetsong tsa latex.
Hydroxyethyl cellulose HEC ke "thickener" e sebelisoang hangata ha ho etsoa liphahlo 'me e na le melemo e latelang:
(1) Ho feto-fetoha ho matla ha Hydroxyethyl cellulose HEC ke polymer e se nang ionic e qhibilihang ka metsing e ka sebelisoang ka bongata ba pH (2-12). E ka kopanngoa le likarolo tsa liaparo tse tloaelehileng (tse kang li-pigments, li-additives, letsoai le qhibilihang le li-electrolyte) ntle le liketsahalo tse sa tloaelehang. the
(2) Kaho e ntle. Ho roala ho teteaneng ka hydroxyethyl cellulose HEC ho na le pseudoplasticity, kahoo e ka sebelisoa ka borashe, ho fafatsa, ho roala rolara le mekhoa e meng ea kaho. Melemo, ho lekanya le hona ho molemo. the
(3) Ha ho na phello e mpe ho filimi ea ho roala. Ka lebaka la litšoaneleho tse sa bonahaleng tsa tsitsipano ea metsi holim'a metsi a tharollo ea metsi a HEC, ha ho bonolo ho foam nakong ea kaho le tlhahiso, 'me ho na le tšekamelo e fokolang ea ho hlahisa masoba le likoti tsa seretse se chesang. the
(4) Tsoelo-pele e ntle ea mebala. Hydroxyethyl cellulose HEC e na le miscibility e babatsehang e nang le li-binders le li-colorants tse ngata, e le hore pente e lokiselitsoeng e be le botsitso bo botle ba mebala le ho tsitsisa.
(5) Botsitso bo botle ba polokelo. Nakong ea polokelo ea pente, e ka boloka ho fanyeha le ho senyeha ha pigment, ntle le mathata a ho phaphamala le ho thunya. Ho na le lera le fokolang la metsi holim'a pente. Ha mocheso oa polokelo o fetoha, viscosity ea eona e lula e tšoana. tsitsitseng haholoanyane.
