tus neeg sawv cev hydrophobing
Tus neeg sawv cev HD828 hydrophobic yog cov kua mis dawb uas tsis muaj zog. Tom qab ntxiv cov khoom no, zaj duab xis hydrophobic tuaj yeem tsim rau ntawm qhov chaw ntawm cov xim dej thiab qhov chaw ntawm cov qhov hauv, yog li dej tsis tuaj yeem nkag mus rau hauv sab hauv ntawm cov xim dej. Yog li, qhov tsis kam dej, tsis kam alkali thiab kev txhuam ntawm cov xim dej tau zoo dua. Ntxiv 1% -2% rau cov xim latex sab nraud ntawm phab ntsa tuaj yeem ua rau muaj kev txhuam ntau dua ob npaug. Vim yog kev tsim cov zaj duab xis hydrophobic ntawm qhov chaw, qhov chaw yog dej tsis kam (cov nyhuv lotus), uas ua rau cov xim dej tsis kam ntau dua.
