Liyini izinga lokushisa lengilazi (Tg) lamampushana e-polymer ahlakazeka kabusha?

Izinga lokushisa le-glass-transition (Tg) lama-polymer powders ahlakazeka kabusha lingahluka kuye ngokuthi i-polymer ethile esetshenzisiwe. Izimpushana ze-polymer ezihlakazeka kabusha ngokuvamile zenziwa ngama-polymer ahlukahlukene njenge-vinyl acetate ethylene (VAE), i-vinyl acetate versatate (VAE VeoVa), ne-ethylene vinyl acetate (EVA), phakathi kokunye.

I-Tg ye-VAE-based redispersible polymer powders ngokuvamile isukela cishe ku- -10°C kuya ku-10°C. I-Tg ye-EVA-based redispersible polymer powders ingahluka kakhulu kuye nge-copolymer ethile ye-EVA esetshenzisiwe, kodwa ngokuvamile iba ku -50°C kuya ku-0°C.

Kubalulekile ukuqaphela ukuthi i-Tg yezimpushana ze-polymer ezihlakazeka kabusha zingathinta izakhiwo nokusebenza kwazo ezinhlelweni ezihlukene, njengamasistimu kasimende, izinto zokunamathisela zamathayili, nama-renders. Ngakho-ke, kubalulekile ukucabangela i-Tg yempushana ethile ye-polymer esetshenziswayo nokuthi ingathinta kanjani isicelo esihlosiwe.
