Girazi zvigadzirwa zvakanyanya kuomarara, asi zvinogona kukamurwa kuita main raw materials uye ebetsero mbishi zvinhu zvinoenderana nemabasa avo.Iyo mikuru yemidziyo inoumba muviri mukuru wegirazi uye inoona iyo huru yemuviri uye kemikari zvimiro zvegirazi.Iwo ebetsero mbishi zvinhu zvinopa girazi zvakakosha zvivakwa uye zvinounza nyore kune maitiro ekugadzira.
1. Iyo huru yezvigadzirwa zvegirazi
(1) Silika jecha kana borax: Chinhu chikuru chesilika jecha kana borax yakaunzwa mugirazi isilicon oxide kana boron oxide, iyo inogona kunyungudutswa mumuviri mukuru wegirazi panguva yekupisa, iyo inosarudza iyo huru yegirazi, uye inonzi silicate girazi kana boron maererano.Girazi remunyu.
(2) Soda kana munyu weGlauber: Chinhu chikuru chesoda uye munyu weGlauber wakaunzwa mugirazi sodium oxide, iyo inogona kuumba fusible yakapetwa kaviri munyu ine acidic oxides senge silica sand panguva yecalcination, iyo inoshanda sekuyerera uye inoita kuti girazi rive nyore. kuumba.Nekudaro, kana zvirimo zvakakurisa, mwero wekuwedzera wekupisa kwegirazi uchawedzera uye simba rekusimba richadzikira.
(3) Limestone, dolomite, feldspar, nezvimwewo: Chinhu chikuru che limestone chinounzwa mugirazi ndeye calcium oxide, iyo inowedzera kugadzikana kwemakemikari.
uye simba remagetsi regirazi, asi zvakawandisa zvemukati zvinokonzeresa girazi kudonha uye kuderedza kupisa kwekudzivirira.
Dolomite, seyakagadzirwa kuunza magnesium oxide, inogona kuvandudza kujeka kwegirazi, kuderedza kuwedzera kwekupisa uye kugadzirisa kudzivirira kwemvura.
Feldspar inoshandiswa seyakagadzirwa kuunza alumina, iyo inogona kudzora tembiricha yekunyungudika uye kugadzirisa kusimba.Mukuwedzera, feldspar inogona kupawo potassium oxide kuti ivandudze kuwedzera kwekushisa kwegirazi.
(4) Girazi cullet: Kazhinji, hazvisi zvese zvitsva zvinoshandiswa pakugadzira girazi, asi 15% -30% cullet inosanganiswa.
2, zvinhu zvekubatsira zvegirazi
(1) Decolorizing mumiriri: Kusachena mune zvakabikwa zvinhu senge iron oxide zvinounza ruvara kugirazi.Soda ash, sodium carbonate, cobalt oxide, nickel oxide, nezvimwewo zvinowanzoshandiswa se decolorizing agents.Ivo vanoonekwa mugirazi kuti vaenderane nemuvara wepakutanga, kuitira kuti Girazi rive risina ruvara.Pamusoro pezvo, kune maajenti ekudzikisa mavara anogona kuumba makomisheni akajeka-mavara ane tsvina yemavara.Semuyenzaniso, sodium carbonate inogona oxidize ne iron oxide kuita iron dioxide, iyo inoita kuti girazi rishanduke kubva kugirinhi kuenda kuyero.
(2) Coloring agent: Mamwe simbi oxides anogona kunyungudika zvakananga mugirazi mhinduro kupenda girazi.Semuenzaniso, iron oxide inogona kuita girazi yero kana girini, manganese oxide inogona kuve yepepuru, cobalt oxide inogona kuve yebhuruu, nickel oxide inogona kuve brown, copper oxide uye chromium oxide inogona kuve yakasvibira, nezvimwe.
(3) Refining agent: Iyo yekujekesa inogona kuderedza viscosity yegirazi kunyunguduka, uye kuita kuti mabhuru anogadzirwa nemakemikari reaction nyore kupukunyuka uye kujekesa.Inowanzo shandiswa kujekesa maajenti anosanganisira white arsenic, sodium sulfate, sodium nitrate, ammonium munyu, manganese dioxide zvichingodaro.
(4) Opacifier: Opacifier inogona kuita kuti girazi rive mukaka chena translucent muviri.Inowanzo shandiswa opacifiers ndeye cryolite, sodium fluorosilicate, tin phosphide uye zvichingodaro.Vanogona kuumba 0.1-1.0μm zvimedu, izvo zvakaturikwa mugirazi kuita girazi opaque.
