cov khoom

piav qhia luv luv:

Cov khoom siv no tshwj xeeb yog siv rau kev tsim cov txheej txheem dej tsis zoo.High elasticity, tuaj yeem ua tau raws li lub teeb ci ntawm lub tsev, thiab tuaj yeem npog cov thermal expansion thiab txias contraction, tawg, tawg thiab lwm yam ua rau tsawg dua 8 hli tawg; tuaj yeem ua tau. tsim ncaj qha rau ntawm lub hauv paus ntub dej, txwv rau lub ces kaum thiab cov xau nyob ib ncig ntawm lub raj xa dej; Muaj zog adhesion, cov khoom xyaw nquag hauv txheej tuaj yeem nkag mus rau hauv cov cement puag saum npoo ntawm qhov pores, micro-cracks thiab cov tshuaj tiv thaiv, thiab cov substrate yog kev sib xyaw. rau hauv ib txheej ntawm crystalline compact waterproof txheej; Kev tiv thaiv ib puag ncig, tsis muaj tshuaj lom, tsis muaj mob, tuaj yeem siv ncaj qha rau hauv dej haus engineering; Acid tsis kam, alkali tsis kam, kub tsis kam, nrog kev laus ua haujlwm zoo thiab zoo corrosion kuj, tuaj yeem siv sab nraum zoov , muaj huab cua tsis zoo.
