I-HEC inomsebenzi wokuqinisa nokwenza ngcono amandla okubamba amapende kumapende e-latex.
I-HEC (i-Hydroxyethyl cellulose) iyi-polymer encibilika emanzini enokulungiswa okuhle kwe-viscosity, encibilika emanzini nasezincibilikiseni eziphilayo, futhi ingakha ama-emulsion azinzile emanzini.Inokumelana okuhle kakhulu kwe-halogen, ukumelana nokushisa kanye ne-alkali, kanye nokuzinza okuphezulu kwamakhemikhali.I-HEC isetshenziselwa ukuthuthukisa i-viscosity kapende we-latex, ukuzinzisa izakhiwo zefomula, ukuvimbela ukuhlangana kopende we-latex, ukuthuthukisa ukunamathela, amandla aqinile, ukuguquguquka nokugqoka ukumelana kwefilimu yokumboza, okuyingxenye yobuchwepheshe yokuthuthukiswa kwefilimu. upende we-latex wekhwalithi ephezulu.
Umsebenzi oyinhloko we-HEC ukuthuthukisa izakhiwo zemishini ye-coating.Ingasetshenziswa futhi njenge-anti-sedimentation ejenti, i-preservative noma i-anti-viscosity agent.Ngaphandle kokugxilisa i-HEC, ingakwazi ukwandisa ngokuphumelelayo i-viscoelasticity yokugqoka, ikhulise amandla okuqina kanye nokuguquguquka kokugqoka, futhi iqede ukuncipha nokuqhekeka kwefilimu.
I-Hydroxyethyl cellulose ihlinzeka ngezakhiwo ezinhle kakhulu zokuhlanganisa ze-latex coatings, ikakhulukazi i-PVA ephezulu.Lapho i-coating ishubile, i-flocculation ngeke ivele.
I-Hydroxyethyl cellulose inomphumela wokujiya ophezulu.Inganciphisa umthamo, ithuthukise umnotho wefomula, futhi ithuthukise ukumelana nokukhuhla kokunamathela.
Isixazululo esinamanzi se-hydroxyethyl cellulose asisona i-Newtonian, futhi izakhiwo zesisombululo zibizwa ngokuthi i-thixotropy.
Esimeni esimile, uhlelo lokumboza luhlala luqinile futhi luvulekile ngemva kokuba umkhiqizo usuhlakazwe ngokuphelele.
Esimweni esithululiwe, uhlelo lugcina izinga elilinganiselwe le-viscosity, okwenza umkhiqizo ube nomswakama omuhle kakhulu, futhi awuchaphazi.
Ku-brush kanye ne-roll coating, umkhiqizo kulula ukusabalalisa ku-substrate.Ilungele ukwakhiwa.Ngesikhathi esifanayo, inokumelana okuhle kwe-splash.Lapho ukugqoka sekuqediwe, i-viscosity yesistimu ibuyiselwa ngokushesha, futhi ukugqoka ngokushesha kuveza ukugeleza ukulenga.
