Ubushinwa: Amatafari ya silica arwanya umuriro, aturuka mu nganda n'abayakora | Rongsheng

Amatafari ya silica arwanya aside kandi afite ubushobozi bwo kurwanya isuri ya aside. Ubushyuhe bw'amatafari ya silica bugera kuri 1640 ~ 1690℃, ubushyuhe bw'ibanze bwo koroshya ni 1620 ~ 1670℃ kandi ubucucike nyakuri ni 2.35g / cm3. Amatafari ya silica ashobora gukoreshwa mu bushyuhe bwinshi igihe kirekire kandi agatuma ingano igumana ubuziranenge nta gihinduka. Amatafari ya silica akoresha SiO2 arenga 94%. Amatafari ya silica afite ubushyuhe bwinshi kandi arwanya ubushyuhe buke. Amatafari ya silica akozwe mu mabuye ya silica karemano nk'ibikoresho fatizo, yongerwamo mineralizer ikwiye kugira ngo itere quartz mu mubiri w'icyatsi kibisi yahinduwe tridymite kandi ishyushye buhoro buhoro mu bushyuhe bwa 1350 ~ 1430℃ mu kirere giciriritse. Iyo ubushyuhe bugeze kuri 1450℃, hari 1.5 ~ 2.2% by'ubwiyongere bw'ingano yose. Uku kwaguka nyuma yo kwaguka bizatuma ingingo zishyirwa mu mashanyarazi kandi zizemeza ko inyubako igumana umwuka mwiza kandi ikagira imbaraga mu nyubako.

Imiterere y'amatafari yo gutwika ya Silika

• Ubudahangarwa bwiza bw'isuri,
• Ubushyuhe bwinshi,
• Ubushyuhe bwinshi: 1690 ~ 1710°C,
• RUL yo hejuru: hafi 1620-1670℃,
• Ubudahangarwa bw'ingano ku bushyuhe buri hejuru,
• Ubudahangarwa bwiza bw'ubushyuhe.

Imiterere y'itafari rya Silika rikoreshwa mu muriro

Ibumba rya silicon ni itafari rihindura imiterere ya silica rirenga 93%, tridymite 50%-80%, cristobalite 10%-30%, cristobalite, quartz na glass phase, hafi 5%-15%. Imiterere y'amabuye y'agaciro y'itafari rya silicate ahanini ni quartz na quartz, ndetse n'ingano nto ya quartz na vitreous. Quartz ya Scale, quartz ya quartz na quartz isigaye ihinduka cyane mu bunini bitewe n'impinduka mu ishusho ya kristu ku bushyuhe buke, bityo ubushyuhe bw'itafari rya silicate rihindura imiterere bugabanuka ku bushyuhe buke. Mu ikoreshwa, ubushyuhe buri munsi ya 800 ℃ buragabanuka, kugira ngo hirindwe kononekara. Bityo rero, ubushyuhe buri munsi ya 800 ℃ ntibugomba gusimbuka mu itanura.

Uburyo bwo gukora amatafari ya silica yo gutwika

Amatafari ya silicate akorwa muri quartzite hamwe n'umusemburo muto w'ubutare. Iyo atwitswe ku bushyuhe bwinshi, imiterere y'amabuye y'agaciro ya silica igizwe na quartz, quartz, ikirahure n'izindi ngingo zikomeye zikozwe ku bushyuhe bwinshi, kandi ingano ya AiO2 irenga 93%. Mu matafari ya silica akoreshwa neza, ingano ya quartz ni yo iri hejuru, ingana na 50% ~ 80%. Cristobalit ni yo yakurikiyeho, ingana na 10% kugeza 30% gusa. Ingano ya quartz n'iy'ibirahure ihinduka hagati ya 5% na 15%.

Ibisobanuro by'amatafari ya Silika yo mu muriro ya Rongsheng

Gukoresha amatafari yo gutwika ya Silika

Amatafari ya silica akoreshwa cyane cyane nk'ibikoresho bikingira urukuta rw'icyumba cyo gutekesha n'ibikoresho bitwika mu itanura rya coke, icyumba cyo kuvugurura no mu mufuka w'ibishishwa mu itanura rifunguye, itanura ryo kwibiramo n'itanura rishongesha ikirahure, n'ahandi hantu ho gutwara ibiro no hejuru mu itanura rya ceramic. Amatafari ya silicate ashobora kandi gukoreshwa mu gice cyo gutwara ibiro mu bushyuhe bwinshi no hejuru mu itanura rifunguye aside.
