Isitena esinganyangekiyo kwi-asidi sisitena esinganyangekiyo esinokumelana ne-asidi eyomeleleyo kunye nezitena ezinokumelana ne-asidi zinokusetyenziswa ngokubanzi kwimizi-mveliso. Ibhlokhi enganyangekiyo kwi-Acid yeyona nto ifanelekileyo yokukhetha iprojekthi yakho kunye neempawu zabo zoxinzelelo lobungqina, ukuxhathisa umhlwa, ukucoca ngokulula kunye nokuxhathisa isiseko se-asidi. iibhloko ezixhathisayo ze-asidi zinesakhiwo esixineneyo, esinokuxhathisa nasiphi na isalathisi se-pH se-alkaline kubushushu obuqhelekileyo, kodwa singaxhathisi ukunyibilika kwealkali kubushushu obuphezulu. i-acid resistant firebrick engaphezulu kwe-93% yeSiO2 umxholo, yamkele i-silica njengeyona nto iphambili ekrwada kwaye inokumelana nokhukuliseko lwe-asidi eziko lwe-slag. Ubungqina be-asidi yesitena somlilo sisetyenziswa kakhulu kuzo zonke iintlobo zeziko kunye neekoni ezinecandelo lemichiza ye-asidi.
Imathiriyeli engundoqo ye-firebrick yobungqina be-asidi yiquartz, i-feldspar kunye nodongwe, ibhloko ye-asidi yobungqina be-refractory luhlobo lwemathiriyeli echasene ne-corrosive nge-oksijeni yobushushu obuphezulu. Ubungqina be-asidi yesitena esiphikisayo sineempawu zokumelana ne-asidi ephezulu, ukufunxa kwamanzi aphantsi, akukho lula ukuba i-oxidized kwiqondo lokushisa eliqhelekileyo, akukho lula ukungcoliswa nguphakathi. ngaphandle kwe-asidi ye-hydrofluoric kunye ne-asidi ye-phosphoric eshushu, ibhlokhi yomlilo yobungqina be-asidi ineempawu ezibalaseleyo zokunqanda ukubola kwiklorini emanzi, amanzi anetyuwa, i-hydrochloric acid, i-sulfuric acid, i-hydrogen nitrate kunye nenye i-asidi kunye nayo nayiphi na i-alkaline yoxinzelelo kubushushu obuqhelekileyo.

Njengoko ipropathi eyomeleleyo yokumelana ne-asidi yesitena sobungqina be-asidi, ingasetyenziswa kwizixhobo zobushushu obuphezulu kunye nomoya we-asidi kunye nokhukuliseko lwe-slag, kwaye ibhloko yobungqina be-asidi ingasetyenziswa ngokubanzi kulwakhiwo lwe-lining yenqaba, i-pool, itanki, i-groove ye- i-petroleum, imboni yeekhemikhali, isichumisi sekhemikhali, ikhemesti, ukutywala, imveliso yobisi, ukwenza iphepha, i-smelt, i-chemical fiber kunye ne-electroplating, i-laboratory yekhemikhali, ukuveliswa kombane, igesi kunye nolunye ushishino.
Umzi-mveliso we-RS refractory ngumboneleli weebhloko zobungqina beasidi eyasekwa ekuqaleni kweminyaka yama-90 yenkulungwane yamashumi amabini. Umzi-mveliso we-RS refractory ukhethekileyo kwizitena ezinobungqina be-asidi ngaphezulu kweminyaka engama-20. ukuba unemfuno ethile yebhlokhi ye-chrome ye-magnesite, okanye unemibuzo malunga nezitena ezinganyangekiyo kwi-asidi malunga nezalathi zenyama kunye neekhemikhali, nceda uqhagamshelane nathi simahla. kunye ne-Rs refractory factory njengomenzi wezitena okwaziyo ukumelana neasidi e-china, uneengenelo ezithile zokukhuphisana ngolu hlobo lulandelayo:
