Kodi kutentha kwa galasi-transition (Tg) kwa ufa wa polima wotayikanso ndi kotani?

Kutentha kwa galasi-kusintha (Tg) kwa ufa wa polima wotayikanso kumatha kusiyanasiyana kutengera polima womwe wagwiritsidwa ntchito. Redispersible polima ufa nthawi zambiri amapangidwa kuchokera ku ma polima osiyanasiyana monga vinyl acetate ethylene (VAE), vinyl acetate versatate (VAE VeoVa), ndi ethylene vinyl acetate (EVA), pakati pa ena.

Tg ya VAE-based redispersible polima ufa nthawi zambiri imakhala kuyambira -10°C mpaka 10°C. Tg ya EVA-based redispersible polima ufa amatha kusiyana mosiyanasiyana kutengera EVA copolymer yomwe imagwiritsidwa ntchito, koma nthawi zambiri imakhala pa -50 ° C mpaka 0 ° C.

Ndikofunikira kudziwa kuti Tg ya ufa wa polima wotayikanso imatha kukhudza momwe amagwirira ntchito komanso magwiridwe antchito osiyanasiyana, monga mumakina a simenti, zomatira matailosi, ndi ma renders. Chifukwa chake, ndikofunikira kulingalira Tg ya ufa wa polima womwe umagwiritsidwa ntchito komanso momwe ungakhudzire zomwe mukufuna.
