Sebenzisa: I-PPH lulwelo olungenambala olucacileyo olunevumba elimnandi elimnandi nelimnandi. Iimpawu zayo ezingenabungozi nezinobuhlobo nokusingqongileyo zokunciphisa isiphumo sepeyinti i-V°C ziyamangalisa. Njengoko i-coalescent isebenza kakuhle, i-emulsion yamanzi eyahlukeneyo kunye neengubo zokusasazeka kwipeyinti ecwebezelayo kunye ne-semi-gloss iyasebenza kakhulu. Yi-vinyl acetate, i-acrylic esters, i-styrene - isinyibilikisi esinamandla seentlobo ezahlukeneyo ze-acrylate polymer, incinci enyibilikayo emanzini (ngaphantsi kwesantya somphunga wamanzi, inceda amasuntswana avuvukileyo), ukuqinisekisa ukuba ifunxwa ngokupheleleyo ngamasuntswana e-latex, yenze ifilimu yokugquma eqhubekayo ebalaseleyo ukunika i-latex coalescence ukusebenza okungcono kunye nophuhliso lombala, kodwa ikwanozinzo oluhle lokugcina. Xa kuthelekiswa nezongezo eziqhelekileyo zokwenza ifilimu ezifana ne-TEXANOL (i-ester yotywala eyenziwe ekhaya yi--12), yenziwe ngokupheleleyo kwifilimu, i-gloss efanayo, ukugeleza, i-anti-sagging, uphuhliso lombala, phantsi kwe-scrub kunye nezinye iimeko, i-PPH inciphisa ubungakanani obumalunga ne-30-50%. Amandla okugquma aqinileyo, ukusebenza kakuhle kokufakwa okuhlanganisiweyo amaxesha ayi-1.5-2, iindleko zemveliso ziye zehla kakhulu. Kwi-emulsions ezininzi, i-PPH yongeza kwi-emulsion ubungakanani be-3.5-5%, ubuncinci bobushushu bokwenza ifilimu (MFT) ukuya kuthi ga kwi--1°C.
Idosi:
1. I-PPH icetyiswa ukuba yongezwe ngaphambi kokuba i-emulsion iqale, okanye yongezwe kwinqanaba lokusila i-pigment, ukuze iifomyula ze-PPH kunye nezinye izithako zihlanganiswe lula, kungcono ukuba zixutywe kwaye zisasazwe, kwaye ngaloo ndlela aziyi kuchaphazela uzinzo lwe-pigment kunye nesini esifanayo.
2. Ngokubanzi, isixa esongeziweyo se-3.5 ukuya kwi-6% ye-acrylic emulsion, i-acrylic emulsion yongezwa kwi-2.5-4.5% ye-styrene-acrylic ngokubanzi yi-2-4%.
Iphakheji:Iidrama zeplastiki ezingama-200 kg /iidrama okanye ezingama-25 kg /zeplastiki ngokweemfuno zabathengi.
Indawo yokugcina:Le mveliso ayiyongozi, kufuneka igcinwe kwindawo epholileyo neyomileyo.
