Acid resistant bricks yog ib lub cib refractory uas muaj zog acid kuj thiab acid resistant cib tuaj yeem siv dav hauv kev lag luam. Acid resistant thaiv yog qhov zoo tshaj plaws xaiv rau koj qhov project nrog lawv cov yam ntxwv ntawm cov pov thawj siab, corrosion kuj, yooj yim los ntxuav thiab acid puag. acid resistant blocks muaj cov qauv ntom, uas tuaj yeem tiv taus cov pH qhov taw qhia alkaline nruab nrab hauv qhov kub thiab txias, tab sis tsis tiv thaiv melting alkali nyob rau hauv kub. acid resistant firebrick nrog ntau dua 93% SiO2 cov ntsiab lus, txais silica ua cov khoom siv tseem ceeb thiab tuaj yeem tiv taus cov kua qaub slag yaig. acid pov thawj hluav taws cib yog siv nyob rau hauv tag nrho cov hom ntawm furnaces thiab kilns nrog acid tshuaj tivthaiv.
Cov khoom tseem ceeb ntawm cov kua qaub pov thawj firebrick yog quartz, feldspar thiab av nplaum, acid proof refractory block yog ib yam khoom siv los tiv thaiv corrosive los ntawm kub oxygenolysis. acid pov thawj refractory cib muaj cov yam ntxwv ntawm cov kua qaub siab, tsis tshua muaj dej nqus, tsis yooj yim rau oxidized ntawm qhov kub thiab txias, tsis yooj yim rau kev qias neeg los ntawm nruab nrab. tshwj tsis yog cov hydrofluoric acid thiab kub phosphoric acid, acid pov thawj hluav taws thaiv muaj cov khoom tiv thaiv zoo rau cov chlorine ntub dej, saline dej, hydrochloric acid, sulfuric acid, hydrogen nitrate thiab lwm yam kua qaub thiab cov concentration alkaline ntawm qhov kub thiab txias.
