Acid kugonjetsedwa castable amatchedwanso refractory castable, amene ndi chimodzi mwa zinthu refractory, ndipo akhoza kukana kukokoloka kwa asidi, amene chimagwiritsidwa ntchito mu sanali chitsulo zitsulo, makampani mankhwala, chimney, etc. castable ali apamwamba zili zomangira wothandizila ndi chinyezi ndi zambiri zamadzimadzi. Unshaped refractory ili ndi mafayilo ambiri ogwiritsira ntchito ndipo imatha kugwiritsidwa ntchito pothira kapena kuthamangitsa molingana ndi kusankha kwazinthu zothandizira zida ndi zomangira.
Acid resistant castable process process ndi yosavuta popanda zida zapadera. Acid kugonjetsedwa castable ali mkulu makina mphamvu ndi apamwamba. Ndiosavuta kupanga pogwiritsa ntchito njira yothira. Zowonongeka za Acid zitha kugwiritsidwa ntchito mwachindunji muukadaulo popanda kuwombera. Ndipo asidi kugonjetsedwa refractory castable akhoza kukana asidi sing'anga dzimbiri 800 ~ 1200 ℃ akhoza kuthira amatchedwa refractory asidi kusamva castable. Refractory acid resistant castable imapangidwa ndi galasi lamadzi monga binder, asidi kapena alkali acid refractory monga aggregate ndi ufa, ndi pang'ono coagulant. Komabe, ma castings oterowo sagonjetsedwa ndi dzimbiri ndi alkali, hydrochloric acid, hydrofluoric acid ndi mafuta ambiri.
Ambiri zikuchokera asidi kugonjetsedwa castable ndi: asidi zosagwira refractory aggregate (60-70%), ufa (30-40%), ndi sodium fluorosilicate (13% -16%) monga kuumitsa wothandizira.

Acid kugonjetsedwa castable chimagwiritsidwa ntchito mu asidi petrochemical chomera ndi sulfuric acid chomera.
Acid resistant refractory castable imatha kuponyedwa mumzere wa thupi komanso imatha kupangidwa kukhala zinthu zotayidwa kale. amene ankagwiritsa ntchito linings a ng'anjo zosiyanasiyana ndi kilns, ndi asidi kugonjetsedwa castable chimagwiritsidwa ntchito mu ng'anjo mafakitale a mafakitale zitsulo, makampani mafuta, makampani mankhwala, zomangira ndi zomangamanga makampani kukana mkulu kutentha kukokoloka.
RS refractory fakitale ndi katswiri asidi kusamva castable katundu amene anakhazikitsidwa mu 90 oyambirira a zaka makumi awiri. RS refractory fakitale ali apadera mu castables asidi kusamva kwa zaka zoposa 20. ngati muli ndi zofuna za refractory acid resistant castable, kapena muli ndi mafunso okhudzana ndi zizindikiro zakuthupi ndi zamankhwala, chonde titumizireni kwaulere. ndi Rs refractory fakitale monga akatswiri asidi kusamva castable wopanga ku China, ali ndi ubwino mpikisano motere:
