Parizvino, magirazi emarara anogadzirwa muminda yekugadzirwa uye yehupenyu ari kuwedzera uye ari kuva njodzi kune veruzhinji. Nekuda kwekugadzikana kwemakemikari emagirazi emarara, haaori, haapisi, haanyungudike kana kunyungudika muvhu. HCMilling (Guilin Hongcheng) ikambani inogadziragirazichigayo chekukuya Zvishandiso. Zvinotevera ndizvo zvinotiudza nzira dzekushandisa magirazi kuti adzokorore kushandiswa.

  girazichigayo chekukuya 

Girazi ratinoshandisa pari zvino rakagadzirwa nejecha re quartz, soda ash, feldspar uye limestone kuburikidza nekupisa kwakanyanya. Chinhu chakasimba chisina chimiro chinowanikwa nekuwedzera viscosity yekunyunguduka panguva yekutonhora. Chinopfava uye chinoonekera. Kune girazi re quartz, silicate glass, soda lime glass, fluoride glass, nezvimwewo. Kazhinji zvinoreva silicate glass, iyo inogadzirwa nejecha re quartz, soda ash, feldspar uye limestone nekusanganisa, high temperature melting, homogenizing, processing uye annealing. Inoshandiswa zvakanyanya mukuvaka, kushandiswa kwezuva nezuva, kurapa, makemikari, electronic, instrument, nuclear engineering nedzimwe nzvimbo. Parizvino, kudzokorodza magirazi kunonyanya kugadzirwa kuita girazi upfu nekukuya, iyo inoshandiswa nenzira dzinotevera:

1. Upfu hwegirazi hunogadzirwa sesimbi yesimbi: chinhu chikuru chegirazi isimbi inoshanda, saka inogona kuva nechinhu chinopenya mushure mekukuyiwa kuita upfu, uye inogona kushandiswa sekusanganiswa kugadzira kongiri. Izvi hazvingogadziri dambudziko rekurasa magirazi chete, asiwo zvinosimudzira kugadzirwa kwezvinhu zvekuvaka zvegirini. (1) Zvinhu zvine simende yakasimba kwazvo zvine simba rekudzvanya pamusoro pe100MPa zvinogona kugadzirwa nekusanganisa upfu hwegirazi. Kana huwandu hweupfu hwegirazi huri pasi pe20%, simba rekudzvanya remuenzaniso rinowedzera nekuwedzera kwehuwandu hweupfu hwegirazi; Kuwedzera kwekupisa kunogadzirisa kunobatsirawo kune pozzolanic reaction yeupfu hwegirazi. Saka, inogonawo kukurudzira kukura kwesimba. (2) Upfu hwegirazi hune simba guru repozzolanic uye kuzadza mugelling system. Haingogone kuzadza mapores ari muchimiro cheslurry chete, asiwo kuita kuti igadzire CSH gel, kuvandudza microstructure yezvinhu uye kuwedzera simba rezvinhu.

2. Kugadzira hupfu hwegirazi sezvinhu zvegirazi: girazi rinoraswa rinounganidzwa, rinorongwa uye rinobatwa sezvinhu zvekugadzira girazi, inova ndiyo nzira huru yekudzokorodza girazi rinoraswa. Girazi rinogona kushandiswa kugadzira zvigadzirwa zvegirazi zvine zvinodiwa zvishoma pamakemikari, ruvara uye tsvina, zvakaita segirazi remabhodhoro rine mavara, girazi rinovhara, zvidhinha zvegirazi risina chinhu, girazi remugero, girazi rakaiswa mavara, bhora regirazi rine mavara nezvimwe zvigadzirwa zvegirazi. Huwandu hwemagirazi anoraswa muzvigadzirwa izvi hunowanzova pamusoro pe30wt%, uye huwandu hwemagirazi anoraswa akasanganiswa muzvigadzirwa zvemabhodhoro egirini nejagi hunogona kusvika pamusoro pe80wt%. Kana 50wt% yemagirazi anoraswa akadzokororwa muChina, matani mamiriyoni 3.6 ezvinhu zvesiliceous, matani mamiriyoni 0.6 emasoda ash uye matani miriyoni imwe emarasha anogona kuchengetwa gore rega rega.

3. Kugadzira hupfu hwegirazi sezvinhu zvekuputira: Japan Changsheng Wood Fiber Board Company inoshandisa matayi emagirazi nemarara kuti apwanywe kuita hupfu hwakatsetseka uye asanganiswe mupurasitiki nenzira yakati, iyo inogona kutsiva silica nezvimwe zvinhu zviri mupurasitiki. Inoshandiswa kupwanya mabhodhoro egirazi asina chinhu akadzokororwa, kukwesha mipendero nemakona, uye kuagadzira kuita mipendero yakachengeteka, kuitira kuti igadzire magirazi akapwanyika ane chimiro chakafanana nejecha rechisikigo, uye wozoasanganisa nehuwandu hwakaenzana hwependi. Uye kupa magadzirirwo nemaitiro izvo pendi yekare yakanga isina. Rudzi urwu rwependi runogona kugadzirwa kuita pendi yemotokari inonyungudika mumvura. Zvinhu zvinoshandisa rudzi urwu rwependi yegirazi yakasanganiswa zvinogona kuburitsa kupenya kwakapararira kana zvikaiswa pamwenje yemotokari kana chiedza chezuva, izvo zvine mhedzisiro mbiri yekudzivirira tsaona nekushongedza.

4.Kukuya girazi mkurwara inoshandiswa kugadzirisa zvinhu zvegirazi zveceramics: girazi receramics rakaoma, rine simba guru remakanika, kugadzikana kwakanaka kwemakemikari uye kugadzikana kwekupisa. Zvisinei, mutengo wekugadzira zvinhu zvechinyakare zvinowanzoshandiswa zvegirazi receramics wakakwira. Munyika dzekunze, kugadzirwa kwegirazi receramics kuchishandisa marara egirazi kubva mukuita kwefloat uye ash inobhururuka kubva mumagetsi panzvimbo pegirazi rekare kwakabudirira. Izvi zvegirazi receramics zvinogadzirwa nenzira yehunyanzvi yekubatanidza kunyunguduka nekunyunguduka: kusanganisa ash inobhururuka negirazi remarara, kunyunguduka pa1400 ℃, kugadzira girazi risina chimiro, kudzima mvura, kukuya, uye kunyunguduka pa810 ~ 850 ℃, zvinogona kugadzirwa kuita girazi receramics rine hunhu hwakanaka hwemakanika, izvo zvinoshanda mumunda wekuvaka. Vaongorori vesainzi vanobva kuTsinghua University neWuhan University of Technology muChina vakabudirira kugona tekinoroji yakakosha yekushandisa ash inobhururuka, gangue yemarasha, tailings dzakasiyana-siyana dzeindasitiri, slag yekunyungudutsa uye silt yeYellow River sezvinhu zvikuru zvekugadzira mapaneru ekushongedza egirazi receramics.

5. Girazi remosaic rinogadzirwa negirazi rinogaya: pwanya girazi remarara zvakanaka kuita upfu hwegirazi, wobva wawedzera imwe glue, colorant kana decolorant, wozvisanganisa zvakaenzana nemuchina wekusanganisa. Batch inodzvanywa mu green body nenzira yekudzvanya yakaoma, uye green body yakaomeswa inotumirwa ku roller kiln, pusher kiln kana tunnel kiln ine tembiricha yekupisa ye800 ~ 900 ℃ kuti isvine, uye inowanzogara munzvimbo yekupisa inopisa kwemaminetsi gumi nemashanu kusvika makumi maviri nemashanu. Zvigadzirwa zvinotonhorerwa kubva mukiln zvinofanirwa kuongororwa, kusarudzwa, kurongwa, kuomeswa, kuongororwa, kurongedzwa, kuchengetwa kana kuendeswa, uye zvigadzirwa zvisina kukodzera zvinofanirwa kudzokororwa.

6. Kugadzira nekugadzira zvinhu zvinodzivirira kupisa uye zvinodzivirira ruzha nekushandisa muchina wekukuya girazi: girazi refuro rudzi rwezvinhu zvakaita segirazi zvine huremu hudiki, simba guru, uye zvakazara nemaburi madiki. Chikamu chegasi chinoumba 80% - 95% yehuwandu hwese hwezvigadzirwa. Kana tichienzanisa nezvimwe zvinhu zvinodzivirira kupisa uye zvinodzivirira ruzha, zvine zvakanakira zvekudzivirira kupisa zvakanaka uye kushanda zvakanaka kwekudzivirira ruzha, kusapisa, kuramba ngura, kuramba chando, kusapisa, kubatana nyore uye kugadzirisa. "Maitiro ayo ekugadzira ndeyekupwanya girazi remarara, Wedzera calcium carbonate, carbon powder - rudzi rwechinhu chinofuridzira furo uye chinokurumidza furo, zvisanganise zvakaenzana, zviise muforoma, uye zviise muchoto kuti zvidziye. Pasi pemamiriro ekunyorovesa tembiricha, wedzera chinhu chinofuridzira furo kuti ugadzire mabubbles pagirazi, wobva wagadzira girazi refuro. Mushure mekunge girazi rabviswa muchoto, richabviswa, rochekwa, uye rochekwa kusvika pahukuru hwakajairwa.

Semhando yechinhu chinowanikwa, magirazi emarara ndiyo nzira yakanakisisa yekudzokorodza magirazi akawanda nekushandisa mukuvaka. Zvakabuda muongororo yazvino zvakaratidza kuti zvinokwanisika kushandisa magirazi emarara semusanganiswa wemaminerari ekongiri, asi kushandiswa kwemaindasitiri hakuna kubudirira nekuda kwetekinoroji yemidziyo nezvimwe zvikonzero.girazichigayo chekukuyayakagadzirwa neHCMilling (Guilin Hongcheng) ndiyo michina mikuru inopa kugadzirwa kwemaindasitiri kwehuwandu hwemagirazi ekudzokorodza. Inoshandiswa pakukuya magirazi, uye inogona kuwana matani akawanda emuchina paawa imwe neimwe, uye inogona kugadzira upfu hwegirazi hwemambure 80-600.
