I-Hydroxyethylcellulose (HEC) i-nonionic, i-polymer e-soluble yamanzi ephuma kwi-cellulose esetyenziswa ngokubanzi kumashishini ahlukeneyo, kubandakanywa imboni yokugquma njenge-thickener kunye ne-stabilizer. Ipeyinti yeLatex, eyaziwa ngokuba yipeyinti esekwe emanzini, luhlobo oludumileyo lwepeyinti esebenzisa amanzi njengesithwala endaweni yezinyibilikisi zesintu. Ukongezwa kwe-HEC kwiipende ze-latex kunokuba nemiphumo eyahlukeneyo ebalulekileyo kwiipropati kunye nokusebenza kwepeyinti.
Thickener:
Omnye wemisebenzi ephambili ye-HEC kwipeyinti ye-latex kukusebenza njenge-thickener. Inika i-viscosity kwipeyinti, ikhusela ukuba iqhube kakhulu kwaye iphucule iimpawu zayo zokusebenza. Oku kubalulekile ekufezekiseni ukhuseleko kunye nokuthintela i-splatter ngexesha lokufaka isicelo.
Phucula ibrashi:
Umphumo wokuqina we-HEC unceda ukuphucula ukuxubha. Inceda ipeyinti ibambelele kumphezulu ngokufanelekileyo, ukunciphisa ukuvuza kunye nokuqinisekisa usetyenziso olulula. Oku kubaluleke kakhulu ekufezekiseni ukugqitywa kobugcisa kwi-DIY kunye nezicelo zemizi-mveliso.
Thintela ukuntywila kunye nokuvuza:
I-HEC inceda ukuthintela ipeyinti yelatex ukuba ingagxuphuleki kwaye ithontsize kumphezulu othe nkqo. Ukunyuka kwe-viscosity ye-HEC iqinisekisa ukuba ipeyinti ibambelela kumphezulu ngaphandle kokukhupha, ivumela ukuba kufakwe isicelo esilawulwayo nesichanekileyo.
Uzinzo oluphuculweyo lokugcina:
I-HEC inegalelo ekuzinzeni kwexesha elide lepeyinti ye-latex ngokuthintela ukuhlukana kwesigaba kunye nokuhlaliswa kwee-pigments. I-polymer yenza inethiwekhi ezinzileyo ngaphakathi kwengubo, ikhusela amacandelo aqinileyo ukuba ahlale phantsi kwesitya. Oku kubalulekile ukugcina umgangatho wepeyinti ngexesha lokugcinwa kunye nokuthutha.
Uzinzo lwe-Emulsion:
Ipeyinti yeLatex ngokuyimfuneko i-emulsion ezinzileyo yamanzi, iinqununu ze-polymer kunye ne-pigments. I-HEC inceda ukuzinzisa le emulsion, ukukhusela ukubambisana kunye nokuqinisekisa ukuba ipeyinti ihlala injalo. Olu uzinzo lubalulekile ekugcineni ukuthembeka kwepeyinti kwixesha elide.
Phucula ukuhamba kunye nomgangatho:
Ukongezwa kwe-HEC kunokuphucula ubumanzi kunye neempawu zokulinganisa zepeyinti ye-latex. Oku kuvelisa ukugqitywa okugudileyo, ngakumbi nangaphezulu komphezulu, ukunciphisa ukubonakala kwamanqaku ebrashi okanye amanqaku e-roller. Ukuqukuqela okuphuculweyo kukwanceda ukuphucula isakhono sepeyinti sokuzilinganisa, ukwenza isiphelo esijongeka njengengcali.
Ukuhambelana nezinye izongezo:
I-HEC iyahambelana nezongezelelo ezininzi ezisetyenziswa ngokuqhelekileyo kwimizobo yepeyinti ye-latex. Oku kuguquguquka kwenza abavelisi beengubo balungise kakuhle ukusebenza kweemveliso zabo ngokudibanisa i-HEC kunye nezinye izithako ukuphumeza iimpawu ezithile zokusebenza.
Impembelelo kwiimpawu zerheological:
Ukongezwa kwe-HEC kuchaphazela iimpawu ze-rheological zeepeyinti ze-latex, ezifana nokuziphatha kwe-shear thinning. I-polymer ine-pseudoplastic okanye i-shear-thinning behavior, oku kuthetha ukuba i-coating iba yi-viscous encinci phantsi kwe-chear, iququzelele isicelo esilula ngaphandle kokubeka esichengeni ubukhulu obufunekayo xa ukucheba kususiwe. .
Iingqwalasela zokusingqongileyo:
Ngenxa yokuba iipeyinti ze-latex zisekelwe emanzini kwaye i-HECs i-soluble emanzini, ezi zakhiwo zineempembelelo ezisezantsi zokusingqongileyo kunezinye iindlela ezisekelwe kwi-solvent. Ipeyinti yeLatex isebenzisa amanzi njengesithwali kwaye ayinayo i-volatile organic compounds (VOCs), inceda ukunciphisa ungcoliseko lomoya kunye nokudala indawo yokusebenza ekhuselekileyo.
Ukwenziwa kwefilimu kunye nokuqina:
I-HEC inokuchaphazela ukubunjwa kwefilimu yepeyinti ye-latex. Inceda ukwenza ifilimu ehlala ihleli kwaye ibambelele kwindawo epeyintiweyo, inceda ekuphuculeni ixesha elide kunye nokusebenza kwengubo. Oku kubalulekile ukukhusela umphezulu kwizinto zokusingqongileyo ezifana nokufuma kunye nemitha ye-UV.
Ngamafutshane, ukongeza i-HEC kwipeyinti ye-latex ineempembelelo ezininzi ekusebenzeni kwayo. Ukususela ekuphuculeni i-viscosity kunye nokupeyinta ekuphuculeni uzinzo kunye nokubunjwa kwefilimu, i-HEC inceda ukuphucula ukusebenza ngokubanzi kweepende ze-latex, okwenza ukuba ibe yinto eyongezelelweyo exabisekileyo ekuqulunqweni kwepeyinti yamanzi. Impembelelo ethile ye-HEC kwipeyinti ye-latex ixhomekeke kwizinto ezifana nokugxininiswa kwe-HEC esetyenzisiweyo, ukuqulunqwa kwepeyinti, kunye neempawu zokugqibela ezifunwayo zepeyinti.
