Sixhomekeke ekucingeni ngobuchule, ukuphuculwa rhoqo kuzo zonke iinkalo, ukuqhubela phambili kwezobuchwepheshe kwaye ewe, kubasebenzi bethu abathatha inxaxheba ngokuthe ngqo kwimpumelelo yethu.Izitena zeSilica, Inkampani yethu inikezela uluhlu olupheleleyo ukusuka kwintengiso yangaphambi kokuthengisa ukuya kwinkonzo yasemva kokuthengisa, ukusuka kuphuhliso lwemveliso ukuya kuphicotho-zincwadi lokusetyenziswa kolondolozo, ngokusekelwe kumandla obuchwephesha aqinileyo, ukusebenza kakuhle kwemveliso, amaxabiso afanelekileyo kunye nenkonzo egqibeleleyo, siza kuqhubeka nokuphuhlisa, ukubonelela ngeemveliso kunye nezisombululo kunye neenkonzo ezisemgangathweni ophezulu, kunye nokukhuthaza intsebenziswano ehlala ixesha elide nabathengi bethu, uphuhliso oluqhelekileyo kunye nokudala ikamva elingcono.
Izitena zeSilica ezinganyangekiyozizinto ezikhuselayo ezisemgangathweni ophezulu ezisetyenziswa kakhulu kwiindawo ezahlukeneyo zoshishino ezinobushushu obuphezulu.
1. Ulwazi oluSisiseko
Izinto eziphambili:Yinto enokuchasana ne-asidi ene-silicon dioxide (SiO₂) njengeyona nto iphambili, edla ngokuba nomxholo ongaphezulu kwe-93%, kwaye eyezitena ze-silica ezikumgangatho ophezulu ingafikelela kwi-96%.
Ulwakhiwo oluqhelekileyo lweekhemikhali:Ngaphandle kweSiO₂, ikwanayo nenani elincinci le-Al₂O₃ (malunga ne-0.8% - 1%), i-MgO (malunga ne-0.001%), i-CaO (malunga ne-0.002%), kunye ne-Fe₂O₃ (malunga ne-0.7% - 1.5%).
Iimpawu Zomzimba:Ukungaguquguquki ngokubanzi kuphakathi kwe-1770°C kunye ne-2000°C. Ukungaguquguquki phantsi komthwalo we-0.2MPa yi-1630°C - 1680°C. Amandla okutyumza abandayo yi-30 - 35MPa, ubuninzi bobuninzi yi-1.8g/cm³, kwaye i-porosity ebonakalayo yi-21% - 22%.
2. Inkqubo yeMveliso
Inkqubo yemveliso ibandakanya ukukhethwa kwezinto eziluhlaza, ukubumba, ukutshisa, kunye nokupholisa. Izinto eziluhlaza eziphambili yi-quartz, kwaye izinto zokubopha ezifana nelayimu kunye nezinto eziphilayo zongeza. Emva kokuba zenziwe zibe ziindawo ezingenanto zezitena, zitshiswa kubushushu obuphezulu be-1350°C - 1430°C. Inkqubo yokutshisa ifuna ulawulo oluchanekileyo lobushushu, kwaye inkqubo yokupholisa nayo kufuneka yenziwe kancinci ukuze kuthintelwe ukuqhekeka okubangelwa kukutshintsha komthamo ngokukhawuleza.
Iimbonakalo:
1. Ukumelana okunamandla nokukhukuliseka kwe-asidi ye-slag:Izitena zesilika zinokumelana kakhulu nezinto ezirhabaxa ezifana ne-asidi slag kunye nesinyithi esinyibilikisiweyo, okuqinisekisa ubomi bazo obude.
2. Ubushushu bokuthambisa umthwalo ophezulu:Ubushushu bokuthambisa umthwalo wezitena ze-silica bufikelela kwi-1640-1670℃, kwaye umthamo uzinzile xa usetyenziswa ixesha elide kubushushu obuphezulu.
3. Uzinzo oluhle lwevolumu:Kubushushu obuphezulu be-1600℃, izitena ze-silica zinokugcina isakhiwo sizinzile kwaye zibe nesantya esiphantsi sokurhubuluza.
4. Uzinzo oluphezulu lweekhemikhali:Izitena zeSilica zinokumelana kakuhle nee-oxides ezifana ne-Al2O3, i-FeO, i-Fe2O3, kodwa azikwazi ukumelana kakuhle ne-alkaline slag (ezifana ne-CaO, i-K2O, i-Na2O).
