Isitini Esiyi-Silica Refractory | Isitini Esishisayo Esimelana Ne-SiO₂ Acid Esiphezulu Sesithando Somlilo Esishisa Kakhulu
Ukuze sibe yisigaba sokufeza amaphupho abasebenzi bethu! Ukwakha abasebenzi abajabule kakhulu, abanobunye kakhulu nabangochwepheshe! Ukuze sifinyelele inzuzo efanayo yabathengi bethu, abaphakeli, umphakathi kanye nathi ngokwethu.Isitini Esiyi-Silica Refractory, Manje sinethimba elihle kakhulu elihlinzeka ngensizakalo yochwepheshe, impendulo esheshayo, ukulethwa ngesikhathi, ikhwalithi enhle kakhulu kanye nentengo engcono kakhulu kumakhasimende ethu. Ukwaneliseka kanye nesikweletu esihle kuwo wonke amakhasimende kuyinto eza kuqala kithi. Besilokhu silangazelela ukubambisana namakhasimende emhlabeni wonke. Sikholelwa ukuthi singanelisa nani. Siyawamukela ngemfudumalo amakhasimende ukuthi avakashele inkampani yethu futhi athenge imikhiqizo yethu.
Izitini ze-silica eziphikisayoziyizinto eziphikisayo zekhwalithi ephezulu ezisetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni enokushisa okuphezulu.
1. Ulwazi Oluyisisekelo
Izingxenye Eziyinhloko:Kuyizinto eziphikisayo ezine-asidi ene-silicon dioxide (SiO₂) njengengxenye eyinhloko, ngokuvamile enokuqukethwe okungaphezu kuka-93%, kanti okwezitini ze-silica ezisezingeni eliphezulu kungafinyelela cishe ku-96%.
Ukwakheka Kwamakhemikhali Okuvamile:Ngaphandle kwe-SiO₂, iqukethe nenani elincane le-Al₂O₃ (cishe u-0.8% - 1%), i-MgO (cishe u-0.001%), i-CaO (cishe u-0.002%), kanye ne-Fe₂O₃ (cishe u-0.7% - 1.5%).
Izakhiwo Ezibonakalayo:Ukungazweli ngokuvamile kuphakathi kuka-1770°C no-2000°C. Ukungazweli ngaphansi komthwalo ongu-0.2MPa kungu-1630°C - 1680°C. Amandla okuchoboza abandayo angu-30 - 35MPa, ubuningi bungu-1.8g/cm³, kanti ukuvuleka okubonakalayo kungu-21% - 22%.
2. Inqubo Yokukhiqiza
Inqubo yokukhiqiza ihlanganisa ukukhethwa kwezinto zokusetshenziswa, ukwakheka, ukudubula, kanye nokupholisa. Izinto zokusetshenziswa eziyinhloko yi-quartz, futhi izihlanganisi ezifana ne-lime kanye nezihlanganisi eziphilayo ziyangezwa. Ngemva kokwakheka zibe yizitini ezingenalutho, zidunyiswa ekushiseni okuphezulu okungu-1350°C - 1430°C. Inqubo yokudubula idinga ukulawulwa okuqondile kokushisa, futhi inqubo yokupholisa nayo idinga ukwenziwa kancane ukuze kugwenywe imifantu ebangelwa ukushintsha kwevolumu ngokushesha.
Izici:
1. Ukumelana okunamandla nokuguguleka kwe-asidi slag:Izitini ze-silica zinamandla okumelana nezinto ezibolayo njenge-asidi slag kanye nensimbi encibilikisiwe, okuqinisekisa ukuthi zihlala isikhathi eside.
2. Izinga lokushisa eliphakeme lokuthambisa:Izinga lokushisa lokuthambisa umthwalo wezitini ze-silica liphezulu njengo-1640-1670℃, futhi ivolumu izinzile uma isetshenziswa isikhathi eside ekushiseni okuphezulu.
3. Ukuqina kwevolumu okuhle:Uma izinga lokushisa liphezulu lika-1600℃, izitini ze-silica zingagcina isakhiwo sizinzile futhi zibe nesivinini esiphansi sokukhukhuleka.
4. Ukuqina kwamakhemikhali okuphezulu:Izitini ze-silica zinokumelana okuhle nama-oxide afana ne-Al2O3, i-FeO, i-Fe2O3, kodwa azimelani kahle ne-alkaline slag (njenge-CaO, i-K2O, i-Na2O).
