Ubushyuhe bwikirahure (Tg) ni ubuhehe bwa polymer ifu?

Ubushyuhe bwikirahure (Tg) bwifu ya polymer ifu irashobora gutandukana bitewe na polymer yihariye yakoreshejwe. Ifu isubirwamo ya polymer isanzwe ikorwa muri polymers zitandukanye nka vinyl acetate etylene (VAE), vinyl acetate versatate (VAE VeoVa), na acetate ya Ethylene vinyl (EVA), nibindi.

Tg ya VAE ishingiye kuri redispersible polymer ifu isanzwe iri hagati ya -10 ° C na 10 ° C. Tg ya EVA ishingiye kuri redispersible polymer ifu irashobora gutandukana cyane bitewe na kopi ya EVA ikoreshwa, ariko mubisanzwe iri hagati ya -50 ° C kugeza 0 ° C.

Ni ngombwa kumenya ko Tg ya pisitori ya polymer isubirwamo ishobora kugira ingaruka kumiterere yabyo no mubikorwa byayo bitandukanye, nko muri sisitemu ya sima, ibyuma bifata neza, hamwe na render. Kubwibyo, ni ngombwa gusuzuma Tg yifu ya polymer yihariye ikoreshwa nuburyo ishobora kugira ingaruka kubisabwa.
