Indlela yokukhetha isanti yequartz siliceous acid refractory

Ekubeni kukho abavelisi abaninzi be-quartz sand siliceous refractory kwimarike, ukhuphiswano phakathi kwabo lubukhali. Emva kokuthelekisa ngokubanzi izinto ezahlukeneyo zokuchasa, bonke bacinga ukuba kufuneka bathathele ingqalelo xa kuthengwa emarikeni. Ziziphi iingongoma eziziintloko ofanele uzifunde?

Ukucatshulwa kwesanti ye-quartz kunye nabavelisi be-siliceous refractory ngumba wokuqala oza kubanjwa kwinkqubo yokuthelekisa kwimarike. Kuphela emva kokumisela iimpawu zexabiso zomenzi ngamnye, inkqubo yokukhetha iya kuba yinto eyahlukileyo. Kukho uhlalutyo oluqhubekayo lomsantsa phakathi kwabavelisi. Oku kukwaneliseke kakhulu kwinkqubo yokhetho eziswa yinkqubo yothelekiso. Yonke into imele ihlalutywe ngokubanzi kwimarike ukubona umsantsa wexabiso kunye nohlahlo lwabiwo-mali lweendleko phakathi kwabavelisi. .

Iimfuno zobugcisa zokulungiswa kwesanti ye-quartz kunye ne-siliceous refractories nazo kufuneka zithelekiswe. Kuphela emva kokuhlalutya rhoqo amanqaku aphambili, uya kukwazi ukuba yeyiphi eyona ingcono kumgangatho xa ukhetha kwiimarike. Ngokombono wokhetho Ngamanye amazwi, ndivakalelwa kukuba yonke imiba kufuneka ishwankathelwe ukuze ikwazi ukumisela umahluko phakathi komenzi ngamnye. Oku kunokubonwa ekuhambeni kokhuphiswano ukuba imigangatho yomgangatho kunye nokusebenza kwe-refractories iyahluka, kwaye kufuneka ibe kwimarike. Emva kokuthelekisa ngokucophelela kwinkqubo yokuthengisa, sinokumisela ukuba ngubani oza kuba neenzuzo ezininzi kwaye ufanelekile ukuthembela kwabathengi.
