Lintlha tsa tsebo ka Hydroxyethyl Cellulose (HEC CAS:9004-62-0)

Sebopeho:Hydroxyethyl Cellulose (HEC CAS:9004-62-0) ke phofo e tšoeu kapa e mosehla e sa nkheng, e sa nkheng, ebile e phalla habonolo.E qhibiliha ka metsing a batang le metsing a chesang, empa hangata ha e qhibilihe ka har'a metsoako e mengata ea tlhaho.PH ea boleng e fetoha hanyenyane sebakeng sa 2-12, empa viscosity e fokotseha ho feta mefuta ena.

Boleng:Hydroxyethyl Cellulose (HEC CAS:9004-62-0) ke setenya se sebelisoang hangata bakeng sa li-inks tsa cellulose ether tse thehiloeng metsing.Ke motsoako oa nonionic o qhibilihang ka metsi o nang le bokhoni bo botle ba ho thibela metsi, o ka senyeha ke oksijene, li-acids le li-enzyme, 'me o ka tšeloa ka Cu2 + tlas'a maemo a alkaline.E tsitsitse ka mocheso, ha e hlahe gel nakong ea mocheso, ha e na pula tlas'a maemo a acidic, 'me e na le thepa e ntle ea ho etsa filimi.Tharollo ea eona ea metsi e ka etsoa lifilimi tse hlakileng, tse ka etsoang ka ketso ea alkaline cellulose le Chemicalbook ethylene oxide, 'me e na le thepa ea ho tiisa, emulsification, adhesion, suspension, film-forming, ho boloka mongobo, le tšireletso ea colloid.Mosebetsi oa li-thickeners li-inks tse thehiloeng metsing ke ho li teteaneng.Ho eketsa li-thickeners ho enke ho eketsa viscosity ea eona, e ka ntlafatsang botsitso ba 'mele le lik'hemik'hale tsa enke;Ka lebaka la ho eketseha ha viscosity, rheology ea enke e ka laoloa nakong ea khatiso;Pigment le filler ka enke ha ho bonolo ho putsoa, ​​​​ho eketsa botsitso ba polokelo ea enke e thehiloeng metsing.

Mokhoa oa Tlhahiso: Alkali cellulose ke polymer ea tlhaho e nang le lihlopha tse tharo tsa hydroxyl ho lesale le leng le le leng la fiber base.Sehlopha se sebetsang ka ho fetisisa sa hydroxyl se arabela ho hlahisa hydroxyethyl cellulose.Kenya linter e tala ea k'hothone kapa makhasi a hloekisitsoeng ka har'a 30% ea alkali ea metsi, 'me ue ntše bakeng sa ho e hatella ka mor'a halofo ea hora.Tobetsa ho fihlela metsi a alkaline a fihla ho 1: 2.8, ebe oe pshatla.Selulose ea alkali e sithabetseng e kenngoa ka har'a mochini oa metsi, e koetsoe, e hloekisoe, ebe e tlatsoa ka naetrojene.Chemicalbook e ile ea hloekisoa khafetsa le ho tlatsoa ka naetrojene ho nka sebaka sa moea o teng ka har'a mochini.Tobetsa ka har'a metsi a pholileng a ethylene oxide, tšela metsi a pholileng ka baking ea mochini oa motlakase, 'me u laole mocheso o ka bang 25 ℃ bakeng sa 2h ho fumana sehlahisoa sa hydroxyethyl cellulose.Sehlahisoa se sa jeleng paate se hlatsuoa ka joala, se senyehile ka acetic acid ho pH 4-6, 'me se hokahane le glyoxal bakeng sa botsofali.Ebe o hlatsoa ka metsi, centrifuge, dehydrate, omisa, 'me u sila ho fumana hydroxyethyl cellulose.
