Sebenzisa
I-PPH iwuketshezi olukhanyayo olungenambala olunephunga elimnandi elimnandi.Akuzona izici ezinobuthi futhi azihambisani nemvelo ukunciphisa umphumela we-V°C kapende kuyamangalisa.Njenge-coalescent ephumelelayo i-emulsion yamanzi ehlukahlukene kanye ne-dispersion coatings kupende we-gloss kanye ne-semi-gloss isebenza kahle kakhulu.I-vinyl acetate, i-acrylic esters, i-styrene - i-solvent enamandla yezinhlobo ezahlukene ze-acrylate polymer, incibilika encane yamanzi (engaphansi kwezinga lokuhwamuka kwamanzi, isiza izinhlayiya ezivuvukalayo), ukuqinisekisa ukuthi imuncwa ngokuphelele yizinhlayiya ze-latex, ezakheke kahle kakhulu. ifilimu enamathelayo eqhubekayo ukuze idlulisele ukusebenza okuhle kakhulu kwe-latex nokuthuthukiswa kombala, kodwa futhi inokugcinwa kokuqina okuhle.Uma kuqhathaniswa nezithasiselo ezijwayelekile ezakha ifilimu ezifana ne-TEXANOL (i-alcohol ester eyenziwe ekhaya -12), ezakheke ngokugcwele efilimini, isicwebezelisi esifanayo, i-fluidity, anti-sagging, ukuthuthukiswa kombala, ngaphansi kokukhuhla nezinye izimo, i-PPH inciphisa inani cishe 30-50%.Ikhono eliqinile lokuhlanganisana, ukusebenza kahle kwe-deposition edidiyelwe izikhathi ezingu-1.5-2, izindleko zokukhiqiza zehle kakhulu.Kuma-emulsion amaningi, i-PPH yengeza ku-emulsion inani elingu-3.5-5%, izinga lokushisa elincane lokubunjwa kwefilimu (MFT) elifika ku- -1°C.
Umthamo
1. I-PPH incoma ukuthi wengeze ngaphambi kwe-emulsion, noma wengeze esigabeni sokugaya umbala, ukuze ukwakheka kwe-PPH nezinye izithako kuhlanganiswe kalula, okungcono kufakwe emulsified futhi kuhlakazwe, futhi ngaleyo ndlela ngeke kuthinte ukuzinza kwebala nobulili obufanayo.
2.Ngokuvamile, inani elingeziwe le-emulsion ye-acrylic engu-3.5 kuya ku-6%, i-emulsion ye-acrylic ye-viniga yengezwe ngenani le-2.5-4.5% ye-styrene-acrylic ngokuvamile i-2-4%.
Iphakheji
200 kg / izigubhu noma 25 kg / izigubhu zepulasitiki futhi ngokuvumelana nezidingo zamakhasimende.
Isitoreji
Lo mkhiqizo uyimpahla engeyona ingozi, kufanele igcinwe endaweni epholile eyomile.
