He aha ka mahana hoʻololi aniani (Tg) o nā pauka polymer redispersible?

Hiki ke ʻokoʻa ka mahana hoʻololi aniani (Tg) o nā pauka polymer redispersible ma muli o ka polymer kikoʻī i hoʻohana ʻia. Hana ʻia nā pauka polymer redispersible mai nā ʻano polymers e like me ka vinyl acetate ethylene (VAE), vinyl acetate versatate (VAE VeoVa), a me ka ethylene vinyl acetate (EVA), a me nā mea ʻē aʻe.

ʻO ka Tg o VAE-based redispersible polymer powders maʻamau mai kahi -10°C a hiki i 10°C. Hiki ke ʻano like ʻole ka Tg o EVA-based redispersible polymer powders ma muli o ka EVA copolymer kikoʻī i hoʻohana ʻia, akā ʻo ka mea maʻamau i ka laulā o -50°C a 0°C.

He mea nui e hoʻomaopopo he hiki i ka Tg o nā pauka polymer redispersible ke hoʻopili i ko lākou mau waiwai a me ka hana ma nā noi like ʻole, e like me nā ʻōnaehana cementitious, tile adhesives, a me nā hana. No laila, he mea nui e noʻonoʻo i ka Tg o ka pauda polymer kikoʻī i hoʻohana ʻia a pehea e pili ai i ka noi i manaʻo ʻia.
