Sebenzisa
I-PPH iwuketshezi olukhanyayo olungenambala olunephunga elimnandi elimnandi. Akuzona izici ezinobuthi futhi azihambisani nemvelo ukunciphisa umphumela we-V°C kapende kuyamangalisa. Njenge-coalescent esebenza kahle 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 imunca ngokuphelele izinhlayiya ze-latex, ezakheke kahle kakhulu. ifilimu enamathelayo eqhubekayo ukuze inikeze ukusebenza okuhle kakhulu kwe-latex nokuthuthukiswa kombala, kodwa futhi inokugcinwa okuhle kokuzinza. Uma kuqhathaniswa nezithasiselo ezijwayelekile ezakha ifilimu ezifana ne-TEXANOL (i-alcohol ester eyenziwe ekhaya ingu-12), ezakheke ngokugcwele efilimini, isicwebezelisi esifanayo, uketshezi oluningi, anti-sagging, ukuthuthukiswa kombala, ngaphansi kokukhuhla nezinye izimo, i-PPH inciphisa inani cishe 30-50%. Amandla okuhlangana aqinile, ukusebenza kahle kwe-deposition edidiyelwe izikhathi eziyi-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 i-emulsion futhi kuhlakazwe, futhi ngaleyo ndlela ngeke kuthinte ukuzinza kwe-pigment 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 ugcinwe endaweni epholile eyomile.
