I-Hydroxyethyl cellulose (HEC) yinto ebalulekileyo engekho i-ionic yamanzi e-soluble polymer compound kunye noluhlu olubanzi lwezicelo kwishishini lepeyinti kunye nokugqoka.
1. Ukutyeba
I-Hydroxyethyl cellulose sisityebi esisebenza kakhulu. Inokunyusa i-viscosity yepeyinti ngokufunxa amanzi kwisisombululo samanzi sokwandisa kunye nokwenza isisombululo se-colloidal. Oku akuncedi kuphela ukuthintela ipeyinti ukuba ihlale ngexesha lokugcinwa kunye nokuthutha, kodwa iphinde iphucule umgangatho wayo kunye neempawu zokumiswa, ukuqinisekisa ukufana kunye nokuguquguquka kwengubo yepeyinti.
2. Ulawulo lwe-Rheological
I-cellulose ye-Hydroxyethyl inokulungelelanisa iimpawu ze-rheological zepeyinti, oko kukuthi, ukuguqula iimpawu zayo zokuhamba ngeendlela ezahlukeneyo zokucheba. Iyakwazi ukugcina ipeyinti kwi-viscosity ethile kwindawo engatshintshiyo ukuthintela ukugoba; kwaye ngexesha lenkqubo yesicelo, i-viscosity iya kuncipha ngokunyuka kwezinga lokucheba, elilungele ukwakhiwa. Le propati inceda ukuphucula ukwakhiwa kunye nokusebenza kakuhle kwepeyinti.
3. Ukugcinwa kwamanzi
I-Hydroxyethyl cellulose inokugcinwa kwamanzi okugqwesileyo. Inokuthintela ngokufanelekileyo ukufuduka kwamanzi ngokukhawuleza, ngaloo ndlela ukwandisa ixesha lokumisa ipeyinti kunye nokuvumela ifilimu yepeyinti ukuba ibe nexesha elaneleyo lokulinganisa kunye nokwakhiwa kwefilimu ngexesha lokumisa. Oku kubaluleke kakhulu kwiipeyinti ezisekelwe emanzini, njengoko ukulahleka kwamanzi ngokukhawuleza kunokubangela iingxaki ezinjengeepinki kunye nokuqhekeka kwifilimu yepeyinti.
4. Ukuzinza kunye neempawu ezichasayo zokuhlalisa
Kwimiqulu yepeyinti, ngakumbi iinkqubo eziqulethe ii-pigments eziqinileyo kunye nezigcwalisi, i-hydroxyethyl cellulose inokubonelela ngokuzinzileyo kokumiswa ngokutyeba. Inokuthintela ngokufanelekileyo i-sedimentation ye-pigments kunye ne-fillers, iqinisekisa ukubunjwa okufanayo kwepeyinti ngexesha lokugcinwa, kwaye ngaloo ndlela iqinisekise ukuhambelana kombala kunye nokuzinza kokusebenza kwengubo.
5. Ukuphucula iimpawu zokwenza ifilim
Iselulosi yeHydroxyethyl inokuphucula iipropati zokwenza ifilim zeepeyinti. Iyakwazi ukwenza uluhlu lwefilimu efanayo phezu kwendawo yokugubungela, ukuphucula i-gloss kunye nokufana kwefilimu yepeyinti. Ukongeza, i-hydroxyethyl cellulose inokuphucula i-anti-powdering kunye nokumelana namanzi kwefilimu yokugquma, ukwandisa ukuqina kwayo kunye neempawu zokuhombisa.
6. Iipropati ezihambelana nokusingqongileyo
Njengoko i-non-ionic thickener, i-hydroxyethyl cellulose ayinayo isinyithi esinzima kunye nezinyibilikisi ezinobungozi, kwaye ihlangabezana neemfuno zokukhusela okusingqongileyo. Ukusetyenziswa kwayo kwiipeyinti ezisekelwe emanzini kunokunciphisa umxholo we-volatile organic compounds (VOCs), onceda ukunciphisa ukungcola kwindalo kunye nokulimala kwimpilo yabantu.
Ukusetyenziswa kwe-cellulose ye-hydroxyethyl kwipeyinti akugcini nje ukuphucula iimpawu ezibonakalayo kunye nokusebenza kokwakhiwa kwemveliso, kodwa ihlangabezana nokukhuselwa kwendalo kunye neemfuno zokhuseleko kwishishini leengubo zanamhlanje. Njengesongezo esisebenzayo, idlala indima ebalulekileyo ekuqulunqweni koyilo kunye nenkqubo yokusetyenziswa kwepeyinti.
