I-Acid resistant castable ikwabizwa ngokuba yi-refractory castable, enye yezinto eziphikisayo, kwaye iyakwazi ukuxhathisa ukhukuliseko lwe-asidi, esetyenziswa ngokubanzi kwisinyithi esingeyontsimbi, imboni yeekhemikhali, itshimini, njl. i-castable inomthamo ophezulu we-ejenti ebophelelayo kunye nokufuma kunye nobuninzi bemali. I-refractory engabunjwanga inefayile ebanzi yesicelo kwaye ingasetyenziselwa ukugalela okanye i-ramming ngokokhetho lweemeko zenkonzo yezixhobo kunye ne-arhente ebophelelayo.
Inkqubo yokuvelisa i-Acid resistant castable ilula ngaphandle kwezixhobo ezikhethekileyo. I-Acid resistant castable inamandla omatshini aphezulu kunye nomgangatho ophezulu. Kulula ukwakha ngendlela yokugalela. I-Acid resistant castables inokusetyenziswa ngokuthe ngqo kubunjineli ngaphandle kokudubula. Kwaye i-asidi ekwaziyo ukumelana ne-refractory castable inokuxhathisa ukubola okuphakathi kwe-asidi ye-800 ~ 1200 ℃ inokugalela ebizwa ngokuba yi-refractory resistant castable. I-Refractory acid resistant castable yenziwe ngeglasi yamanzi njenge-binder, i-asidi okanye i-alkali acid refractory njenge-aggregate kunye nomgubo, kunye nenani elincinci le-coagulant. Nangona kunjalo, ukuphosa okunjalo akuxhathisi ukubola nge-alkali, i-hydrochloric acid, i-hydrofluoric acid kunye namafutha amaninzi.
Ukubunjwa ngokubanzi kwe-acid resistant castable: i-asidi-resistant refractory aggregate (60-70%), i-powder (30-40%), kunye ne-sodium fluorosilicate (13% -16%) njenge-agent enzima.

I-Acid resistant castable isetyenziswa ngokubanzi kwisityalo se-acid petrochemical kunye nesityalo se-sulfuric acid.
I-Acid resistant refractory castable inokuphonswa kumgca womzimba kwaye ingenziwa ibe yimveliso yangaphambili. esetyenziswa ngokubanzi iilayini zamaziko ahlukeneyo kunye neekontini, kunye ne-acid resistant castable isetyenziswa ngokubanzi kwiziko loshishino lwe-metallurgical, ishishini lepetroleum, ishishini lemichiza, izinto zokwakha kunye neshishini lobunjineli lokuxhathisa ukhukuliseko lobushushu obuphezulu.
Umzi-mveliso we-RS refractory ngumthengisi okwaziyo ukumelana neasidi owasekwa ekuqaleni kweminyaka yama-90 yenkulungwane yamashumi amabini. Umzi-mveliso we-RS we-refractory ukhethekileyo kwi-acid resistant castables iminyaka engaphezu kwama-20. ukuba unemfuno ethile ye-asidi exhathisayo enokulahlwa, okanye unemibuzo malunga ne-acid resistant refractory castable malunga neempawu zomzimba kunye neekhemikhali, nceda uqhagamshelane nathi simahla. kunye ne-Rs refractory factory njengomvelisi okwaziyo ukumelana neasidi e-china, ineengenelo ezithile zokukhuphisana ngolu hlobo lulandelayo:
