Isticmaal: PPH waa dareere aan midab lahayn oo hufan oo leh ur macaan oo udgoon leh. Astaamaha aan sunta ahayn iyo kuwa deegaanka u fiican si loo yareeyo saameynta V°C ee rinjiga waa mid cajiib ah. Maadaama dahaarka biyaha ee isku dhafan ee kala duwan iyo dahaarka kala firdhisan ee ku jira gloss iyo semi-gloss ay si gaar ah waxtar u leeyihiin. Waa vinyl acetate, acrylic esters, styrene - dareere xooggan oo ka kooban noocyo kala duwan oo polymer acrylate ah, biyo yar oo milma (ka yar heerka uumiga biyaha, waxay ka caawisaa walxaha bararsan), si loo hubiyo in si buuxda ay u nuugaan walxaha latex, waxay sameeyeen filim dahaar oo joogto ah oo heer sare ah si ay u siiyaan coalexence latex waxqabadka ugu fiican iyo horumarinta midabka, laakiin sidoo kale waxay leedahay xasillooni kaydin oo wanaagsan. Marka la barbar dhigo waxyaabaha lagu daro sameynta filimada caadiga ah sida TEXANOL (ester-ka khamriga ee guriga lagu sameeyo waa -12), oo si buuxda loogu sameeyay filimka, isla dhalaalka, dareeraha, ka hortagga libdhida, horumarinta midabka, hoos u dhigista xoqidda iyo xaaladaha kale, PPH waxay yareysaa xaddiga qiyaastii 30-50%. Awoodda isku-darka xooggan, hufnaanta dhigista isku dhafan 1.5-2 jeer, kharashyada wax soo saarka ayaa si weyn hoos ugu dhacay. Inta badan emulsions-ka, PPH waxay ku dartay emulsion-ka xaddi dhan 3.5-5%, heerkulka ugu yar ee sameynta filimka (MFT) ilaa -1°C.
Qiyaasta:
1. PPH waxay kugula talineysaa inaad ku darto ka hor emulsion-ka, ama ku dar marxaladda shiididda midabka, si qaacidooyinka PPH iyo maaddooyinka kale ay u fududaadaan isku-xidhka, oo la doorbidayo in la emuls gareeyo oo la kala firdhiyo, sidaas darteedna saameyn kuma yeelan doonto xasilloonida midabka iyo jinsiga la midka ah.
2. Guud ahaan, xaddiga lagu daray ee 3.5 ilaa 6% emulsion acrylic, emulsion acrylic ee khalka lagu daray xaddi dhan 2.5-4.5% styrene-acrylic guud ahaan 2-4%.
Xirmada:200 kg / durbaan ama 25 kg / durbaan balaastig ah iyo sida waafaqsan shuruudaha macaamiisha.
Kaydinta:Badeecadani waa alaab aan khatar ahayn, waa in lagu kaydiyaa meel qabow oo qalalan.
