1. Chemistry
Cov tshuaj chloride ions yog qhov tseem ceeb ntawm kev ua vaj tse nyob ntev, vim tias chlorine atoms tuaj yeem ua kev puas tsuaj rau cov kav hlau tshwj xeeb.
Thaum chlorine atoms tshaj qhov txwv tsis pub dhau, cov hlau yuav xeb, pob zeb tawg, cuam tshuam los ntawm cov dej tso tawm, steel xeb sai dua, cuam tshuam loj heev ntawm cov kav ntev.
2. Cov khoom siv raw khoom
Hauv cov khoom siv raw, alkali tseem yog qhov tseem ceeb cuam tshuam rau lub sijhawm ntawm kev ua vaj tse, alkali sib sau los ntawm cov cement, ya cov hmoov tshauv, cov dej ua kom dej, thiab lwm yam.
Alkali-ua ke cov tshuaj tiv thaiv tuaj yeem ua kev puas tsuaj rau pob zeb ua kev tsim kho thiab yog qhov tseem ceeb ua rau lub pas dej tsis ua hauj lwm, yog li tswj cov ntsiab lus alkali yog qhov tseem ceeb heev.
3. Qhov uas tib neeg xav tau
Tus so yog porosity, dej noj, sib xyaw, tiv thaiv kev ntsuas, thiab lwm yam.
Tag nrho cov no tuaj yeem cuam tshuam kom ruaj khov, tab sis lawv kuj yooj yim los tswj.
Tsuav yog muaj cov neeg paub dhau los, hom kev ua yuam kev no feem ntau tsis tshwm sim.
