Izitena ezimelana ne-asidi zizitena ezinganyangekiyo ezinokumelana ne-asidi enamandla kwaye izitena ezimelana ne-asidi zingasetyenziswa kakhulu kumashishini. Ibhloko emelana ne-asidi yeyona ndlela ifanelekileyo yokukhetha iprojekthi yakho ngeempawu zazo zoxinzelelo lokumelana nokugqwala, ukumelana nokugqwala, kulula ukuzicoca kunye nokumelana nesiseko se-asidi. Iibhloko ezimelana ne-asidi zinesakhiwo esixineneyo, esinokumelana nayo nayiphi na indlela ye-pH ye-alkaline kubushushu obuqhelekileyo, kodwa singamelani nokunyibilika kwe-alkali kubushushu obuphezulu. Izitena ezimelana ne-asidi ezinomxholo we-SiO2 ongaphezulu kwe-93%, zamkela i-silica njengezinto eziphambili kwaye zinokumelana nokukhukuliseka kwe-asidi yesitofu. Izitena ezimelana ne-asidi zisetyenziswa kakhulu kuzo zonke iintlobo zezitofu kunye nee-kilns ezine-acid chemical component.
Iipropati zeSitena esiQinisekisa i-Asidi
- Ukumelana nobushushu obuphezulu,
- Amandla aphezulu oomatshini,
- Ukumelana kakuhle nokunxitywa,
- Ukumelana kakuhle nobushushu,
- Ukumelana okuhle nokukhukuliseka kwe-slag yesithando somlilo,
- Ukumelana okunamandla nokukhukuliseka kwe-asidi,
- Ukufunxwa kwamanzi okuncinci kunye nokubonakala okuncinci kwe-porosity.
Inkqubo Yokuvelisa Izitena Ezingqina I-Asidi
Izinto eziphambili ze-firebrick enganyangekiyo yi-quartz, i-feldspar kunye nodongwe, ibhloko enganyangekiyo yi-asidi luhlobo lwezinto ezichasene nokubola ngenxa ye-oxygenolysis yobushushu obuphezulu. Izitena ezinganyangekiyo yi-asidi zineempawu zokuxhathisa i-asidi ephezulu, ukufunxwa kwamanzi okuphantsi, akukho lula uku-oxidized kubushushu obuqhelekileyo, akukho lula ukungcoliswa yi-medium. Ngaphandle kwe-hydrofluoric acid kunye ne-hot phosphoric acid, ibhloko yomlilo enganyangekiyo yi-asidi ineempawu ezintle zokungabola kwi-chlorine emanzi, amanzi anetyuwa, i-hydrochloric acid, i-sulfuric acid, i-hydrogen nitrate kunye nezinye i-asidi kunye naluphi na uxinaniso lwe-alkaline kubushushu obuqhelekileyo.

Ukusetyenziswa kweSitena esiQinisekisa i-Asidi
Njengoko izitena ezichasene ne-asidi zinamandla okuxhathisa i-asidi, zingasetyenziswa kwizixhobo zobushushu obuphezulu ezinomoya we-asidi kunye nokukhukuliseka kwe-slag, kwaye ibhloko echasene ne-asidi ingasetyenziswa kakhulu kulwakhiwo lwe-lining yenqaba, ichibi, itanki, umjelo wepetroleum, ishishini leekhemikhali, isichumiso seekhemikhali, ikhemesti, ukwenziwa kwebhiya, imveliso yobisi, ukwenziwa kwephepha, ukunyibilikisa, ifayibha yeekhemikhali kunye ne-electroplating, ilabhoratri yeekhemikhali, ukuveliswa kombane, igesi kunye neminye imboni.
Umenzi wezitena ezingqina i-asidi ezivela kwi-RS Refractory Factory
I-RS refractory Factory ngumthengisi weebhloko ezichasene ne-asidi ochwephesha owasekwa kwiminyaka yoo-90s yenkulungwane yama-20. I-RS refractory Factory ibigxile kwizitena ezichasene ne-asidi kangangeminyaka engaphezu kwama-20. Ukuba unesidingo se-magnesite chrome block, okanye unemibuzo malunga nezitena ezichasene ne-asidi malunga neempawu zomzimba nezekhemikhali, nceda unxibelelane nathi simahla. Kwaye i-Rs refractory Factory njengomvelisi wezitena ochasene ne-asidi eTshayina, inezibonelelo ezithile zokukhuphisana ngolu hlobo lulandelayo:
- Ixabiso Elikhuphisanayo: Yenza iimveliso zikhuphisane kwimarike yakho,
- Amava amaninzi: Thintela ukuqhekeka kunye nokujija kwezitena,
- Iintlobo ezahlukeneyo zeenkuni: Gcina imali yenkuni kuwe,
- Ulawulo oluQinisekileyo loMgangatho: Hlangana neemfuno zomgangatho wabathengi,
