Thempereichara ea phetoho ea khalase (Tg) ea phofo e ka sebelisoang hape ea polymer ke efe?

Thempereichara ea phetoho ea khalase (Tg) ea phofshoana ea polima e ka fetohang e ka fapana ho latela polima e itseng e sebelisitsoeng. Li-polymer tse ka sebelisoang hape hangata li entsoe ho tsoa ho lipolymer tse fapaneng joalo ka vinyl acetate ethylene (VAE), vinyl acetate versatate (VAE VeoVa), le ethylene vinyl acetate (EVA), har'a tse ling.

Tg ea VAE-based redispersible powder powders hangata e tloha ho -10°C ho isa ho 10°C. Tg of EVA-based redispersible polymer powders e ka fapana haholo ho latela mofuta o itseng oa EVA copolymer e sebelisitsoeng, empa hangata e maemong a -50 ° C ho isa ho 0 ° C.

Ho bohlokoa ho hlokomela hore Tg ea li-polymer powders tse qhalakanhang li ka ama thepa ea tsona le ts'ebetso ea tsona lits'ebetsong tse fapaneng, joalo ka lits'ebetsong tsa cementitious, likhomaretsi tsa lithaele, le li-renders. Ka hona, ho bohlokoa ho nahana ka Tg ea phofo e khethehileng ea polymer e sebelisoang le hore na e ka ama ts'ebeliso e reriloeng joang.
