Iyo mbishi yekugadzira mabhodhoro egirazi.

Iyo huru mbishi yekugadzira mabhodhoro egirazi
Izvo zvakasiyana-siyana zvinoshandiswa kugadzira girazi batch zvinosanganiswa zvinonzi segirazi raw materials. Iyo girazi batch yekugadzirwa kwemaindasitiri musanganiswa weanowanzo 7 kusvika gumi nemaviri emunhu zvikamu. Zvichienderana nehuwandu hwavo uye kushandiswa, Inogona kukamurwa kuita girazi main zvinhu uye accessories.
Iyo huru yakabikwa inoreva chinhu chakasvibirira umo akasiyana constituent oxides anounzwa mugirazi, sejecha requartz, sandstone, limestone, feldspar, soda ash, boric acid, lead compound, bismuth compound, nezvimwewo, izvo zvinoshandurwa kuita girazi mushure mekuparadzwa.
Zvishandiso zvekubatsira zvinhu zvinopa girazi imwe yakakosha kana kukurumidza kunyungudika. Zvinoshandiswa zvishoma, asi zvinoshanda zvakanyanya. Ivo vanogona kukamurwa kuita kujekesa maajenti uye maejenti ekupenda zvichienderana nebasa ravanoita.
Decolorizer, opacifier, oxidant, flux.
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. Zvishandiso zvekubatsira zvinopa zvakakosha zvivakwa kune girazi uye zvinounza nyore kune yekugadzira maitiro.

1, iyo huru yemidziyo yegirazi

(1) Silika jecha kana borax: Chinhu chikuru chejecha resilica kana borax yakaunzwa mugirazi isilika kana boron oxide, inogona kunyungudutswa mumutumbi wegirazi panguva yekupisa, iyo inosarudza iyo huru yegirazi, inodaidzwa kunzi silicate girazi. kana boron. Acid munyu girazi.

(2) Soda kana munyu weGlauber: Chinhu chikuru chesoda uye thenardite yakaunzwa mugirazi is sodium oxide. Mukuita calcination, vanogadzira fusible yakapetwa munyu ine acidic oxide senge silica sand, iyo inoshanda senge inoyerera uye inoita kuti girazi rive nyore kugadzira. Zvisinei, kana zviri mukati zvakawandisa, chiyero chekuwedzera kwekushisa kwegirazi chichawedzera uye simba rekusimba rinoderera.

(3) Limestone, dolomite, feldspar, nezvimwewo: Chikamu chikuru che limestone chinounzwa mugirazi icalcium oxide, iyo inosimudzira kugadzikana kwemakemikari uye kusimba kwemagetsi egirazi, asi iyo yakawandisa inoita kuti girazi rive rakajeka uye rinoderedza kupisa kupisa.

Sechinhu chakasvibirira chekuunza magnesium oxide, dolomite inogona kuwedzera kujeka kwegirazi, kuderedza kuwedzera kwekupisa, nekuvandudza kuramba kwemvura.

Feldspar inoshandiswa seyakabikwa pakuunzwa kwealumina, iyo inodzora tembiricha yekunyungudika uye zvakare inovandudza kusimba. Mukuwedzera, feldspar inogona kupawo potassium oxide zvikamu zvekuvandudza kupisa kwekuwedzera kwegirazi.

(4) Girazi rakaputsika: Kazhinji kutaura, hazvisi zvese zvitsva zvinoshandiswa mukugadzira girazi, asi 15% -30% girazi rakaputsika rinosanganiswa.

2, girazi ebetsero zvinhu

(1) Decolorizing agent: tsvina mune yakabikwa, senge iron oxide, inounza ruvara kugirazi. Soda inowanzoshandiswa, sodium carbonate, cobalt oxide, nickel oxide, nezvimwewo zvinoshandiswa se decolorizing agents, izvo zvinopa mavara anowirirana kune yekutanga ruvara mugirazi. Girazi rinova risina ruvara. Pamusoro pezvo, kune mugadziri wekudzikisa ruvara unokwanisa kugadzira musanganiswa weruvara rwakareruka netsvina ine mavara, senge sodium carbonate iyo inogona kuiswa oxidized ne iron oxide kuti iite ferric oxide, kuitira kuti girazi rishanduke kubva kugirinhi kuenda kuyero.

(2) Colorants: Mamwe maokisi esimbi anogona kunyungudutswa zvakananga mugirazi mhinduro yekupendesa girazi. Kana iyo iron oxide ikaita girazi reyero kana girini, manganese oxide inogona kutaridzika yepepuru, iyo cobalt oxide inogona kuoneka yebhuruu, nickel oxide inogona kuratidzika yebrown, uye copper oxide uye chromium oxide inogona kuoneka yakasvibira.

(3) Kujekesa mumiriri: Iyo inojekesa mumiriri inogona kuderedza viscosity yegirazi kunyunguduka, kuitira kuti mabhuru anogadzirwa nemakemikari reaction anogona kupukunyuka nekujekesa. Inonyanya kushandiswa kujekesa zvinhu ndeyeko, sodium sulfate, sodium nitrate, ammonium munyu, manganese dioxide nezvimwe zvakadaro.

(4) Opacifier: Iyo opacifier inogona kushandura girazi kuita mukaka chena inopenya muviri. Anowanzo shandiswa opacifiers ari cryolite, sodium fluorosilicate, tin phosphide, uye zvakafanana. Vanokwanisa kugadzira zvidimbu zve 0.1 - 1.0 μm zvakaturikwa mugirazi kuti girazi rive opacified.
