Redispersible polymer hmoov txhim kho qhov tsis muaj zog ntawm cov cement mortar xws li brittleness thiab siab elastic modulus, thiab muab cov cement mortar zoo dua thiab tensile daim ntawv cog lus lub zog los tiv thaiv thiab ncua kev tsim cov kab nrib pleb hauv cement mortar. Txij li thaum lub polymer thiab mortar tsim ib tug interpenetrating network qauv, ib tug nruam polymer zaj duab xis yog tsim nyob rau hauv lub pores, uas ntxiv dag zog rau kev sib raug zoo ntawm aggregates thiab blocks ib co ntawm cov pores nyob rau hauv mortar. Yog li ntawd, qhov kev ua tau zoo ntawm cov khoom siv tawv tawv hloov kho tau zoo heev dua li ntawm cov cement mortar.
Raws li cov khoom siv kho kom zoo nkauj tsis tseem ceeb hauv kev kho kom zoo nkauj, phab ntsa putty yog cov khoom siv rau phab ntsa theem thiab kho, thiab yog lub hauv paus zoo rau lwm cov khoom dai. Cov phab ntsa saum npoo tuaj yeem ua kom du thiab zoo ib yam los ntawm kev siv phab ntsa putty, yog li ntawd qhov kev kho kom zoo nkauj tom ntej tuaj yeem ua tau zoo dua. Phab ntsa putty feem ntau yog tsim los ntawm cov khoom siv hauv paus, muab tub lim, dej thiab cov khoom ntxiv. Dab tsi yog lub luag haujlwm tseem ceeb ntawm redispersible polymer hmoov raws li lub ntsiab additive nyob rau hauv phab ntsa putty hmoov?
① Cov teebmeem ntawm cov tshuaj khib nyiab tshiab;
A 、 Txhim kho kev tsim kho kev ua tau zoo;
B 、 Muab kev tuav dej ntxiv txhim kho dej;
C, Ua kom muaj peev xwm ua haujlwm;
D 、 Tsis txhob tawg thaum ntxov
② Cov nyhuv ntawm hardening mortar:
A 、 Txo cov elastic modulus ntawm mortar thiab ua kom nws haum haum nrog lub hauv paus txheej;
B 、 Ua kom yooj yim dua thiab tiv thaiv tawg;
C 、 Txhim kho tsis kam ntawm cov hmoov xau tawm.
D 、 Cov tshuaj tiv thaiv dej los yog txo cov dej nqus
E, Ua kom adhesion rau lub hauv paus txheej.
