Isticmaal
PPH waa dareere daah furnaan leh oo midab leh oo leh ur macaan oo qurux badan. Waa astaamo aan sun lahayn oo deegaanka ah si loo yareeyo saameynta rinjiga v rinjiga ah waa wax la yaab leh. Iyada oo ay tahay in la isku waafajiyo emulsion-ka oo kaladuwan oo buluug ah oo kala soocaya oo ku kala firidhsan oo ah rinjiga gless iyo rinjiga semi-sedexdu si gaar ah ayey waxtar u leedahay. Waa Vinyl acetate, estarers-ka acrylic, styrene - xalka adag ee noocyada biyuhu ka yar yahay, waxay ka dhigan tahay in ay gabi ahaanba kaqaybqaato waxqabadka ugu wanaagsan ee loo yaqaan 'Totx', oo ay sidoo kale ka dhigan tahay kobcinta midabka. Marka la barbardhigo waxyaabaha lagu daro filimka caadiga ah ee 'Texanol' sida Texanol (guryaha aalkolada guryaha lagu sameeyo) -12), oo si buuxda loo sameeyay filimka, dheecaanka, oo ah wax lagu buufiyo, oo hoos yimaada xoqidda, oo hoos timaada, PPH yareynta qaddarka qiyaastii 30-50%. Awoodda isku-dubayga ah ee adag, hufnaanta diyaarinta ee isku dhafan 1.5-2 jeer, qarashaadka waxsoosaarka ayaa si weyn hoos ugu dhacay. Inta badan emulsions, pph oo lagu daro emulsion qaddarka 3.5-5%, heerkulka qaabka filimka ugu yar (MTT) ee ilaa -1 ° C.

Qiyaas daawo
1. PPH waxay kugula talinaysaa in lagu daro ka hor emulsion ka hor, ama ku dar marxaladda giraanka midabka, sidaa darteed qaababka PPP iyo waxyaabaha kale ee la isku daro, oo ay sidaas saameyn ugu yeeshaan xasilloonida doofaarka iyo galmada.
2.Guud ahaan, lacagta lagu daro ee 3.5 illaa 6% emulsion acrylic, emulsion forryllic for khal lagu daray qaddarka 2.5-4.5% loogu talagalay stryse-acrylic guud ahaan 2-4%.
