Gịnị bụ iko mgbanwe okpomọkụ (Tg) nke redispersible polymer powders?

Okpomọkụ iko-ngbanwe (Tg) nke polymer powders nwere ike ịdịgasị iche dabere na polymer a kapịrị ọnụ. A na-emekarị ntụ ntụ polymer redispersible site na ụdị polymer dị iche iche dị ka vinyl acetate ethylene (VAE), vinyl acetate versatate (VAE VeoVa), na ethylene vinyl acetate (EVA), n'etiti ndị ọzọ.

Tg nke VAE ntụ ntụ na-agbanwe agbanwe na-adịkarị site na -10°C ruo 10°C. The Tg nke Eva-based redisspersible polymer powders nwere ike ịdị iche iche dabere na kpọmkwem EVA copolymer eji, ma ọ na-adịkarị na nso nke -50°C ka 0°C.

Ọ dị mkpa iburu n'obi na Tg nke polymer powders redispersible nwere ike imetụta njirimara na arụmọrụ ha na ngwa dị iche iche, dị ka na simenti simenti, tile adhesives, na renders. Ya mere, ọ dị mkpa iji tụlee Tg nke kpọmkwem polymer ntụ ntụ na-eji na otú o nwere ike imetụta ngwa ezubere.
