Daim Ntawv Thov:
PPH yog cov kua tsis muaj xim pob tshab nrog lub ntxhiab tsw qab zoo. Nws tsis muaj tshuaj lom thiab tsis ua rau ib puag ncig puas tsuaj, nws txo cov xim V°C zoo kawg nkaus. Nws muaj txiaj ntsig zoo rau kev sib xyaw ua ke ntawm ntau yam dej emulsion thiab dispersion coatings hauv gloss thiab semi-gloss xim. Nws yog vinyl acetate, acrylic esters, styrene - cov kuab tshuaj muaj zog ntawm ntau hom acrylate polymer, uas yaj tau hauv dej me me (tsawg dua qhov dej evaporation, pab cov khoom o), kom ntseeg tau tias nws raug nqus tag nrho los ntawm cov khoom latex, tsim cov zaj duab xis txheej zoo heev kom muab cov latex coalescence zoo tshaj plaws thiab kev txhim kho xim, tab sis kuj muaj kev ruaj khov zoo. Piv nrog cov khoom siv ua zaj duab xis ib txwm xws li TEXANOL (ua hauv tsev cawv ester yog -12), uas tsim tag nrho hauv zaj duab xis, tib yam gloss, fluidity, tiv thaiv kev sagging, kev txhim kho xim, hauv qab txhuam thiab lwm yam mob, PPH txo cov nyiaj li 30-50%. Muaj peev xwm sib xyaw ua ke muaj zog, kev ua haujlwm sib xyaw ua ke 1.5-2 zaug, cov nqi tsim khoom tau poob qis heev. Rau feem ntau cov emulsions, PPH ntxiv rau cov emulsion ntawm 3.5-5%, qhov kub tsawg kawg nkaus ntawm zaj duab xis tsim (MFT) txog li -1 ° C.
Dosage:
1. PPH pom zoo kom ntxiv ua ntej cov emulsion, lossis ntxiv rau theem sib tsoo xim, yog li PPH cov qauv thiab lwm yam khoom xyaw yooj yim sib txuas, nyiam dua emulsified thiab dispersed, thiab yog li yuav tsis cuam tshuam rau kev ruaj khov ntawm cov xim thiab cov zoo li poj niam txiv neej.
2. Feem ntau, qhov ntxiv ntawm 3.5 txog 6% acrylic emulsion, acrylic emulsion rau vinegar ntxiv rau hauv qhov ntau ntawm 2.5-4.5% rau styrene-acrylic feem ntau 2-4%.
Pob Khoom thiab Chaw Khaws Khoom
1. 200 kg / nruas los yog 25 kg / yas nruas thiab raws li cov neeg siv khoom xav tau.
2. Khaws cov khoom no rau hauv qhov chaw txias, qhuav, thiab muaj cua nkag tau zoo kom deb ntawm cov khoom siv uas tsis sib haum.
