Igiciro cyo hasi cy'amatafari yo mu bwoko bwa 96% ya Sio2 Silika yo mu bwoko bwa Refractory yo mu itanura ry'ibirahure
"Ubunyangamugayo, Udushya, Ubuhanga, no Gukora neza" ni igitekerezo gihoraho cy'ikigo cyacu cyo gutera imbere mu gihe kirekire kugira ngo gifatanye n'abakiriya bacu kugira ngo dufatanye kandi twungukire hamwe.Amatafari yo mu Bushinwa yo mu itanura ry'ibirahure n'amatafari ya Silika ya Sio2, Gutumiza ibicuruzwa byihariye byemewe bifite imiterere itandukanye n'imiterere yihariye y'umukiriya. Twiteguye gushyiraho ubufatanye bwiza kandi burambye mu bucuruzi n'abakiriya bo hirya no hino ku isi.
Amatafari ya silica arwanya ubukanani ibikoresho byiza cyane birwanya ubushyuhe bwinshi bikoreshwa cyane mu nganda zitandukanye zikoresha ubushyuhe bwinshi.
1. Amakuru y'ibanze
Ibice by'ingenzi:Ni ibikoresho birwanya aside birimo silicon dioxide (SiO₂) nk'igice cy'ingenzi, akenshi bifite ibipimo birenga 93%, naho amatafari ya silica meza cyane ashobora kugera kuri 96%.
Ibisanzwe bigize imiti:Uretse SiO₂, irimo kandi ingano nto ya Al₂O₃ (hafi 0.8% - 1%), MgO (hafi 0.001%), CaO (hafi 0.002%), na Fe₂O₃ (hafi 0.7% - 1.5%).
Imiterere ifatika:Ubushyuhe bwo gukonja muri rusange buri hagati ya 1770°C na 2000°C. Ubushyuhe bwo gukonja munsi y'umutwaro wa 0.2MPa ni 1630°C - 1680°C. Ubukonje butuma umuntu asya ni 30 - 35MPa, ubucucike bw'umubyimba ni 1.8g/cm³, naho ubushyuhe bugaragara ni 21% - 22%.
2. Uburyo bwo gukora
Uburyo bwo gukora burimo guhitamo ibikoresho fatizo, kubishyira mu ishusho, kubikuza no kubikonjesha. Ibikoresho by'ingenzi ni quartz, kandi ibikoresho nk'ibifunga by'ishwagara n'ibifunga by'umwimerere byongerwamo. Nyuma yo gushingwa mu matafari, bishyushwa ku bushyuhe buri hagati ya 1350°C na 1430°C. Uburyo bwo kubikuza busaba kugenzura ubushyuhe neza, kandi uburyo bwo kubikuza nabwo bugomba gukorwa buhoro buhoro kugira ngo hirindwe ko ibintu byacitse bitewe n'impinduka zihuse z'ingano.
Ibiranga:
1. Ubudahangarwa bukomeye ku isuri y'ibimera bivanze n'aside:Amatafari ya silica arwanya cyane ibintu byangiza nk'ibishishwa bya aside n'ibyuma bishongeshejwe, bigatuma amara igihe kirekire.
2. Ubushyuhe bwinshi bworoshya umutwaro:Ubushyuhe bwo koroshya umutwaro w'amatafari ya silica buri hejuru ya 1640-1670°C, kandi ingano yayo irahindagurika iyo ikoreshejwe igihe kirekire ku bushyuhe bwinshi.
3. Ingufu nziza zo gupima:Ku bushyuhe buri hejuru bwa 1600℃, amatafari ya silica ashobora kugumana inyubako ihamye kandi akagira umuvuduko muto wo kuzamuka.
4. Ubuziranenge bukabije bw'ibinyabutabire:Amatafari ya silica afite ubudahangarwa bwiza na okiside nka Al2O3, FeO, Fe2O3, ariko nta budahangarwa bwiza na alkaline slag (nka CaO, K2O, Na2O).

1. Amatafari ya silica akoreshwa cyane cyane mu rukuta rugabanya icyumba gishyushyamo karubone n'icyumba gitwika cyo mu itanura rya coke, icyumba gishyushyamo n'icyumba cy'ifuru ifunguye yo mu itanura rikora ibyuma, itanura risanzwe rishyushya, ibikoresho birwanya ubushyuhe byo mu itanura rishongesha ikirahure n'itanura rya ceramic, n'ibindi bice by'itanura.
