I-HEC inomsebenzi wokuqina kunye nokuphucula amandla okuqina kweengubo kwiipende ze-latex.
I-HEC (i-Hydroxyethyl cellulose) i-polymer e-soluble yamanzi kunye nokulungiswa kakuhle kwe-viscosity, i-soluble emanzini kunye ne-solvents ye-organic, kwaye inokwenza i-emulsions ezinzileyo emanzini.Inokumelana okugqwesileyo kwe-halogen, ubushushu kunye nokumelana ne-alkali, kunye nokuzinza okuphezulu kweekhemikhali.I-HEC isetyenziselwa ukuphucula i-viscosity yepeyinti ye-latex, ukuzinzisa iipropati zefomyula, ukuthintela ukudityaniswa kwepeyinti ye-latex, ukuphucula ukunamathela, amandla okuqina, ukuguquguquka kunye nokumelana nokunxiba kwefilimu yokugquma, eyinxalenye yobugcisa bokuphuhliswa kwefilimu. ipeyinti yelatex ekumgangatho ophezulu.
Umsebenzi oyintloko we-HEC kukuphucula iimpawu zomatshini zokugquma.Isenokusetyenziswa njenge-agent anti-sedimentation, i-preservative okanye i-anti-viscosity agent.Ngaphandle kokugxininiswa kwe-HEC, inokunyusa ngokufanelekileyo i-viscoelasticity ye-coating, ikhulise amandla okuqina kunye nokuguquguquka kwengubo, kwaye isuse i-shrinkage kunye nokuqhekeka kwefilimu.
Iselulosi yeHydroxyethyl ibonelela ngeempawu ezigqwesileyo zokwaleka kwiingubo zelatex, ngakumbi iipeyinti eziphezulu zePVA.Xa i-coating inzima, i-flocculation ayiyi kwenzeka.
Iselulosi yeHydroxyethyl inefuthe eliphezulu lokujiya.Inokunciphisa umthamo, iphucule uqoqosho lwefomula, kwaye iphucule ukuxhathisa ukukhuhla kwengubo.
Isisombululo samanzi se-hydroxyethyl cellulose asiyiyo i-Newtonian, kwaye iipropati zesisombululo zibizwa ngokuba yi-thixotropy.
Kwimeko engatshintshiyo, inkqubo yokwaleka ihlala ijiyile kwaye ivulekile emva kokuba imveliso ichithwe ngokupheleleyo.
Kwimeko ethululwayo, inkqubo igcina iqondo eliphakathi le-viscosity, okwenza imveliso ibe ne-fluidity egqwesileyo, kwaye ayichaphazeli.
Kwi-brush kunye ne-roll coating, imveliso kulula ukusabalalisa kwi-substrate.Ilungele ukwakhiwa.Kwangaxeshanye, inokumelana kakuhle nokuchaphaza.Xa i-coating igqityiwe, i-viscosity yenkqubo ibuyiselwa ngokukhawuleza, kwaye i-coating ivelisa ngokukhawuleza i-flow hanging.
