Codsiga:
PPH waa dareere hufan oo aan midab lahayn oo leh ur macaan oo macaan. Waa astaamo aan sun ahayn iyo sifooyin deegaanka u saaxiib ah si loo yareeyo rinjiga V°C saamaynta waa cajiib. Sida dhuxusha wax ku ool ah emulsion biyaha kala duwan iyo daahan kala firdhiyey ee gloss iyo semi-gloss rinjiga ayaa si gaar ah waxtar leh. Waa vinyl acetate, acrylic esters, styrene - dareere xoog leh oo ka mid ah noocyada kala duwan ee polymer acrylate, biyo yar oo milmay (wax ka yar heerka uumiga biyaha, caawinta qaybaha bararsan), si loo hubiyo in ay si buuxda u nuugaan qaybaha cinjirka, sameeyay heer aad u fiican. filim daahan oo joogto ah si ay u bixiyaan coalescence caato ah waxqabadka ugu fiican iyo horumarinta midabka, laakiin sidoo kale waxa uu leeyahay xasilloonida kaydinta wanaagsan. Marka la barbar dhigo daroogooyinka caadiga ah ee samaynta filimada sida TEXANOL (homemade alcohol ester is -12), si buuxda loogu sameeyay filimka, dhalaalid isku mid ah, dareere, anti-sagging, horumarinta midabka, hoos xoqida iyo xaaladaha kale, PPH waxay yaraynaysaa qadarka ku saabsan 30-50%. Awood-dhaqaaleedka xooggan, hufnaanta meelaynta isku-dhafan ee 1.5-2 jeer, kharashyada wax-soo-saarka ayaa si weyn hoos ugu dhacay. Inta badan emulsion-yada, PPH waxay ku dartay emulsion-ka qadar ah 3.5-5%, heerkulka samaynta filimka ugu yar (MFT) ee ilaa -1°C.
Dosage:
1. PPH waxay ku talinaysaa in lagu daro ka hor emulsion , ama ku dar in shiidka midabka, si ay u qaabaynta PPH iyo maaddooyinka kale si fudud isku xidhka, door bidaan emulsified iyo kala firdhiso, oo sidaas ma saamayn doono xasilloonida midabka iyo wixii la mid ah galmada.
2. Guud ahaan, qadarka dheeriga ah ee 3.5 ilaa 6% emulsion acrylic, emulsion acrylic for khal lagu daray qadar 2.5-4.5% for styrene-acrylic guud ahaan 2-4%.
Xidhmada iyo Kaydinta
1. 200 kg / durbaan ama 25 kg / durbaan caag ah iyo sida waafaqsan shuruudaha macaamiisha.
2. Ku kaydi alaabta meel qabow, qalalan, oo hawo fiican leh oo ka fog alaabta aan ku habboonayn.
