Lithini iqondo lobushushu leglasi-lotshintsho (Tg) lwepolymer powders eziphinda zihlakazwe?

Ubushushu beglasi-inguqu (Tg) yepolymer powders ephinda ihlakazwe inokwahluka ngokuxhomekeke kwipolymer ethile esetyenzisiweyo. Iipolymer powders ezinokuphinda zenziwe kwakhona ziqhele ukwenziwa kwiipolymers ezahlukeneyo ezifana nevinyl acetate ethylene (VAE), vinyl acetate versatate (VAE VeoVa), kunye ne-ethylene vinyl acetate (EVA), phakathi kwabanye.

I-Tg ye-VAE-based redispersible polima powders ngokuqhelekileyo isuka ku--10°C ukuya kwi-10°C. I-Tg ye-EVA-based redispersible polymer powders inokwahluka ngokubanzi ngokuxhomekeke kwi-copolymer ethile ye-EVA esetyenzisiweyo, kodwa ngokuqhelekileyo kuluhlu lwe -50 ° C ukuya ku-0 ° C.

Kubalulekile ukuba uqaphele ukuba i-Tg ye-polymer powders ephinda iphinde isetyenziswe inokuchaphazela iipropati zabo kunye nokusebenza kwizicelo ezahlukeneyo, ezifana neenkqubo ze-cementitious, i-adhesives ye-tile, kunye ne-renders. Ke ngoko, kubalulekile ukuqwalasela i-Tg yomgubo wepolymer osetyenziswayo kunye nokuba inokuchaphazela njani usetyenziso olucetywayo.
