Inov Polyurethane Ua Npuas Ncauj Khoom rau Kev Tsim Khoom ntawm Sandal Soles
Pu Sandal Khau Sole System
INTRODUCTION
PU Sandal khau-sole system yog cov ntaub ntawv polyester-based PU system, muaj plaub yam: polyol, ISO, hardner thiab catalyst.Kev ua haujlwm ntawm qhov system no yog ob yam.Nyob rau hauv cov ntaub ntawv no, lub catalyst, nyuaj, tshuab neeg sawv cev thiab pigment yuav tsum tau tov meej nrog cov polyol tivthaiv EXD-3070A ua ntej cov tshuaj tiv thaiv nrog ISO tivthaiv EXD-3022B.Cov khoom siv no yog siv los tsim cov khoom siv qis thiab nruab nrab hardness Sandal, xws li & khau ntaub.Kev ua haujlwm ntawm qhov system feem ntau ua nrog lub tshuab txhaj tshuaj.
