Sebenzisa
I-PPH iwuketshezi olungabonakali olungenambala olunephunga elimnandi elimnandi. Izici zayo ezingezona ezinobuthi futhi ezinobungani nemvelo zokunciphisa umphumela wepende i-V°C ziyamangalisa. Njengoba i-coalescent esebenza kahle, i-emulsion yamanzi ehlukahlukene kanye ne-dispersion coating kupende olucwebezelayo nolucwebezelayo lusebenza kahle kakhulu. I-vinyl acetate, i-acrylic esters, i-styrene - i-solvent eqinile yezinhlobo ezahlukene ze-acrylate polymer, i-water soluble encane (engaphansi kwesilinganiso sokuhwamuka kwamanzi, isiza izinhlayiya ezivuvukele), ukuqinisekisa ukuthi imuncwa ngokuphelele yizinhlayiya ze-latex, yakha ifilimu yokumboza eqhubekayo enhle kakhulu ukuze inikeze i-latex coalescence ukusebenza okuhle kakhulu kanye nokuthuthukiswa kombala, kodwa futhi inokuqina okuhle kokugcina. Uma kuqhathaniswa nezithasiselo ezivamile zokwakha ifilimu ezifana ne-TEXANOL (i-ester yotshwala eyenziwe ekhaya ingu-12), eyakhiwe ngokugcwele efilimini, i-gloss efanayo, i-fluidity, i-anti-sagging, ukuthuthukiswa kombala, ngaphansi kokukhuhla nezinye izimo, i-PPH yehlisa inani elingaba ngu-30-50%. Amandla okubumbana aqinile, ukusebenza kahle kokufakwa okuhlanganisiwe izikhathi ezingu-1.5-2, izindleko zokukhiqiza zehle kakhulu. Kuma-emulsion amaningi, i-PPH yengeze ku-emulsion inani elingu-3.5-5%, izinga lokushisa elincane lokwenza ifilimu (MFT) elifika ku--1°C.
Isilinganiso
1. Kunconywa ukuthi i-PPH ingezwe ngaphambi kokufakwa kwe-emulsion, noma ingezwe esigabeni sokugaya i-pigment, ukuze ukuhlanganiswa kwe-PPH nezinye izithako kube lula, okungcono kube yi-emulsified futhi kuhlakazwe, ngakho-ke ngeke kuthinte ukuzinza kwe-pigment kanye nobulili obufanayo.
2.Ngokuvamile, inani lokwengeza elingu-3.5 kuya ku-6% le-emulsion ye-acrylic, i-emulsion ye-acrylic yengezwe ngenani elingu-2.5-4.5% le-styrene-acrylic ngokuvamile lingu-2-4%.
Iphakheji
200 kg /izigubhu noma 25 kg /izigubhu zepulasitiki futhi ngokwezidingo zamakhasimende.
Isitoreji
Lo mkhiqizo awuyona ingozi, kufanele ugcinwe endaweni epholile neyomile.
