Muhupenyu hwedu hwezuva nezuva, tinowanzo shandisa zvigadzirwa zvegirazi zvakasiyana-siyana, semahwindo egirazi, magirazi, magonhi egirazi anotsvedza, nezvimwewo. Zvigadzirwa zvegirazi zvese zvakanaka uye zvinoshanda. Iyo yakasvibirira yebhodhoro regirazi ijecha requartz seyakanyanya mbishi, uye zvimwe zvinhu zvekubatsira zvinonyungudutswa kuita mvura ine tembiricha yakakwira, uyezve bhodhoro remafuta rakakosha rinopinzwa muforoma, rakatonhodzwa, rakachekwa, uye rinopisa kuti riumbe. bhodhoro regirazi. Mabhodhoro egirazi anowanzo ane zviratidzo zvakaomarara, izvo zvinogadzirwawo kubva kuforoma maumbirwo. Iko kuumbwa kwemabhodhoro egirazi kunogona kukamurwa kuita mhando nhatu: kuvhuvhuta kwemanyorero, mechanika kuvhuvhuta uye extrusion molding zvinoenderana nenzira yekugadzira. Ngatitarisei maitiro ekugadzira mabhodhoro egirazi.
Nzira yekugadzira bhodhoro regirazi:
1. Raw material preprocessing. Iyo yakawanda yakasvibirira (jecha requartz, soda ash, limestone, feldspar, nezvimwewo) inopwanyika, iyo yakanyorova yakaomeswa yakaomeswa, uye iyo ine iron-ine yakasvibira inogadziriswa kuti ivimbise kunaka kwegirazi.
2. Kugadzirira batch.
3. Kunyunguduka. Bachi regirazi rinodziirwa pakupisa kukuru (1550 ~ 1600 madhigirii) mumoto wedziva kana muchoto chedziva kuita yunifomu, isina bubble-isina girazi remvura rinosangana nezvinodiwa zvekuumbwa.
4. Kuumba. Isa girazi remvura muforoma kugadzira girazi chigadzirwa chechimiro chinodiwa, kazhinji preform inoumbwa kutanga, uye ipapo preform inoumbwa mumuviri webhodhoro.
5. Kurapa kwekupisa. Kuburikidza neannealing, quenching uye mamwe maitiro, kushushikana, kupatsanurwa kwechikamu kana crystallization mukati megirazi inocheneswa kana kugadzirwa, uye chimiro chegirazi chinoshandurwa.
