Ukusetyenziswa kwe-cellulose ye-hydroxyethyl (HEC) kwiingubo kuneenzuzo ezininzi, ukugubungela iimpawu zomzimba, iindlela zokucubungula kunye nemiphumo yesicelo.
1. Ukuqina kwesiphumo
I-Hydroxyethyl cellulose sisityebi esisebenzayo esinokunyusa kakhulu i-viscosity yezogquma. Isiphumo salo sokuqina sinokufikelela kwiziphumo ezibalulekileyo kumanqanaba asezantsi okongeziweyo, ngaloo ndlela kuphuculwe ukusebenza kwesicelo sokwaleka. I-viscosity yepeyinti imodareyitha, enokuthi igweme iingxaki ezinjengokuncipha kunye nokudilika ngexesha lokupeyinta, kunye nokuphucula ukufana kokwakhiwa kunye nokukhanya kwefilimu yokugqoka.
2. Ukuphuculwa kozinzo
I-HEC inefuthe elihle lokuzinzisa kwiingubo. Iyakwazi ukuzinzisa ukusasazwa kwee-pigments kunye nezizalisi ngokusebenzisa ukudibanisa ngokomzimba kunye nokusebenzisana kweekhemikhali, ukuthintela ukuhlaliswa kunye nokuchithwa kwee-pigments kunye nezihluzi ngexesha lokugcinwa okanye ukusetyenziswa. Oku akugcini nje ukwandisa ubomi beshelufu yepeyinti kodwa iqinisekisa nokusasazwa kwee-pigments ngexesha lokufaka isicelo.
3. Phucula irheology
I-cellulose ye-Hydroxyethyl inempembelelo enkulu kwi-rheology yokwambathisa, ebangela ukuba i-coating ibonise iimpawu ze-pseudoplastic (shear thinning). Kwizinga eliphantsi lokucheba, ipeyinti igcina i-viscosity ephezulu, ekulungele ukuma nokugcinwa; ngelixa kumazinga aphezulu okucheba (njengaxa uxubha kunye nokutshiza), i-viscosity yepeyinti iyancipha, okwenza kube lula ukuhamba nokusebenzisa. Le propati ye-shear-thinning yenza i-coating ibe lula ukuyisebenzisa ngexesha lokusetyenziswa, kwaye ifilimu yokugqoka igudileyo kwaye injalo.
4. Ukuphucula ukuxhathisa kwe-sag
Xa usebenzisa ipeyinti kwindawo ethe nkqo, i-HEC inokuphucula kakhulu ukuxhathisa kwepeyinti ukuba igxumeke. Oku kubangelwa yimpembelelo yayo yokuqina kunye neempawu ze-rheological ezivumela ipeyinti ukuba ifake ngokukhawuleza isakhiwo esifana nejeli emva kokusetyenziswa, ukunciphisa ukuthambekela kokuhamba, ngaloo ndlela kuthintele ipeyinti ukuba ingabikho kwaye iqhube.
5. Ukuphucula iimpawu zokufumisa
I-HEC igcina ngokufanelekileyo umswakama, ngaloo ndlela yandisa ixesha lokumisa ipeyinti. Oku kubaluleke kakhulu kwezinye iingubo ezifuna ixesha elide lokusebenza, njengepeyinti yokhuni, ipeyinti yobugcisa, njl njl. Ixesha lokumisa elongezelelweyo linika umakhi ixesha elingakumbi lokusebenza kwaye ugweme iimpawu zokupeyinta kunye nobunzima bokwakha obubangelwa ukomisa ngokugqithiseleyo kwepeyinti.
6. Ukuphucula ukusebenza kwebrashi
Ekubeni i-HEC iphucula iipropati ze-rheological kunye nefuthe lokuqina kwepeyinti, ipeyinti ibonisa umgangatho ongcono xa uxutywe. Xa uxubha, ipeyinti inokusasazwa ngokulinganayo ngaphandle kwamanqaku ebrashi, kwaye ifilimu yokugqibela yokugqoka igudileyo kwaye ithambile. Oku kubaluleke kakhulu kwiingubo ezisemgangathweni eziphezulu, ezifana neengubo zefenitshala, iinqwelo zeemoto, njl.
7. Ukulungelelaniswa
I-HEC inozinzo oluhle lweekhemikhali kunye nokuhambelana kwaye iyahambelana neenkqubo ezahlukeneyo zokugubungela, ezifana neengubo ezisekelwe emanzini, iipeyinti ze-latex, iipeyinti ezisekelwe kwioli, njl. izithako, kwaye aziyi kubangela utshintsho lweekhemikhali ngokulula kwifomula.
8. Ukuphucula ukusebenza kokwambathisa
I-HEC ayinikezeli kuphela imiphumo yokuqina kunye nokuzinzisa kwiingubo, kodwa iphinda iphucule iipropati ezibonakalayo zefilimu yokugqoka. Ngokomzekelo, inokuphucula ukuchasana nokuqhekeka, ukuchasana nokukhuhla kunye nokuguquguquka kwefilimu yokugqoka. Oku kwenza i-coating yokugqibela ibe yinto ehlala ixesha elide, ikwazi ukugcina i-aesthetics yayo kunye nokusebenza phantsi kweemeko ezahlukeneyo zokusingqongileyo.
9. Ukhuseleko lokusingqongileyo
I-HEC yimathiriyeli enokubola enezinto ezilungileyo zokusingqongileyo. Xa kuthelekiswa nezinye i-thickeners zokwenziwa, inomthwalo omncinci wokusingqongileyo kwaye ayikhuphi izinto ezinobungozi ngexesha lokusetyenziswa. Oku kuhambelana neemfuno eziphakamileyo zokusingqongileyo kwishishini leengubo zanamhlanje kwaye lilungelelanisa nemfuno yabathengi yeemveliso eziluhlaza.
10. Kulula ukuphatha kunye nokusabalalisa
I-HEC inyibilika ngokulula kwaye isasazeke emanzini kwaye yenze i-viscous liquid efanayo. Kwinkqubo yokuvelisa i-coating, ukuchithwa kwayo kunye nokusabalalisa kwenza inkqubo yokuvelisa ilula kwaye ingabikho kwiingxaki ze-agglomeration okanye ukuchithwa okungagqibekanga, ukunciphisa inkathazo kwinkqubo yokuvelisa kunye nokuphucula ukusebenza kakuhle kwemveliso.
Ukusetyenziswa kwe-hydroxyethyl cellulose kwiingubo kuneenzuzo ezininzi. Ayiphuculi kuphela iipropati ezibonakalayo kunye nokusebenza kokwakhiwa kwengubo, kodwa iphinda ikhulise ukuzinza kunye neempawu zokukhusela okusingqongileyo kwengubo. Idlala indima ebalulekileyo ekuqulunqweni kwepeyinti yanamhlanje, inika izisombululo ezisebenzayo zokufikelela kwimiphumo ephezulu yokupenda. Ngokuphuhliswa kobugcisa bokugquma kunye nokwahluka kweemfuno zemarike, amathuba okusetyenziswa kwe-HEC kwiingubo ziya kuba zibanzi.
