Parizvino, girazi remarara rinogadzirwa mukugadzira uye minda yekugara iri kuwedzera uye kuva njodzi yeruzhinji.Nekuda kwekugadzikana kwekemikari yemarara girazi, haina kuora, kupisa, kunyungudika kana kunyungudika zvakasikwa muvhu.HCMilling(Guilin Hongcheng) mugadziri wegirazikugaya midziyo.Izvi zvinotevera sumo yenzira dzemagirazi ekudzokorodza.

  girazikugaya 

Girazi ratinoshandisa ikozvino rakagadzirwa nejecha requartz, soda ash, feldspar uye limestone kuburikidza nekushisa kwakanyanya.Amorphous solid material inowanikwa nekuwedzera viscosity yekunyunguduka panguva yekutonhora.Iyo ine brittle uye yakajeka.Kune quartz girazi, silicate girazi, soda lime girazi, fluoride girazi, etc. Inowanzoreva silicate girazi, iyo inogadzirwa kubva kujecha requartz, soda ash, feldspar uye limestone nekusanganisa, kupisa kwakanyanya kunyunguduka, homogenizing, kugadzirisa uye annealing.Inoshandiswa zvakanyanya mukuvaka, kushandiswa kwemazuva ese, kurapwa, makemikari, zvemagetsi, chiridzwa, nyukireya engineering uye mamwe minda.Parizvino, kudzokorodza kwegirazi kunonyanya kugadziriswa kuita girazi poda nekukuya, iyo inoshandiswa nenzira dzinotevera:

1. Girazi poda inogadzirwa sesimende base zvinhu: chikamu chikuru chegirazi chinoshanda silica, saka inogona kuva nekuita pozzolanic mushure mekukuyiwa kuita upfu, uye inogona kushandiswa seyakasanganiswa kugadzira kongiri.Izvi hazvigone chete kugadzirisa dambudziko rekurasa girazi remarara, asiwo kukurudzira kuvandudzwa kwezvinhu zvakasvibirira zvekuvaka.(1) Iyo yekupedzisira-yakakwirira simba simende-yakavakirwa zvinhu zvine compressive simba pamusoro pe100MPa inogona kugadzirwa nekusanganisa girazi poda.Apo girasi yehupfu huri pasi pe20%, simba rekumanikidzika remuenzaniso rinowedzera nekuwedzera kwegirasi yehupfu;Kuwedzera kwekushisa kwekuporesa kunobatsirawo kune pozzolanic reaction yegirazi poda Nokudaro, inogonawo kukurudzira kukura kwesimba.(2) Girazi poda ine yakasimba pozzolanic chiitiko uye kuzadza mhedzisiro mune gelling system.Iyo haigone kungozadza pores mune slurry chimiro, asi zvakare kuita kuti igadzire CSH gel, inovandudza iyo microstructure yezvinhu uye kuwedzera simba rezvinhu.

2. Girazi poda yekugadzira segirazi raw material: tsvina yegirazi inounganidzwa, yakarongedzwa uye inobatwa seyakasvibiswa yekugadzirwa kwegirazi, iyo ndiyo nzira huru yekudzokorodza tsvina yegirazi.Girazi remarara rinogona kushandiswa kugadzira zvigadzirwa zvegirazi zvine zvakaderera zvinodikanwa pamakemikari kuumbwa, ruvara uye kusvibiswa, senge girazi remavara bhodhoro, girazi insulator, hollow girazi zvidhinha, chiteshi girazi, embossed girazi, ine mavara girazi bhora uye zvimwe zvigadzirwa zvegirazi.Huwandu hwegirazi remarara hwakasanganiswa mune izvi zvigadzirwa kazhinji pamusoro pe30wt%, uye huwandu hwemarara egirazi yakasanganiswa mubhodhoro regirinhi nezvigadzirwa zvejagi inogona kusvika pamusoro pe80wt%.Kana 50wt% yegirazi yakaraswa ikashandiswazve muChina, 3.6 miriyoni matani esiliceous zvinhu, 0.6 miriyoni matani esoda ash uye 1 miriyoni matani emarasha akajairwa anogona kuchengetwa gore rega.

3. Girazi rekugadzira hupfu sezvinhu zvekuputira: Japan Changsheng Wood Fiber Board Company inoshandisa tsvina yegirazi uye matai emarara kuti iparadzwe kuita poda yakatsetseka uye yakasanganiswa mumucheka mune imwe chikamu, iyo inogona kutsiva silica nezvimwe zvinhu mumucheka.Inoshandiswa kuputsa marara egirazi mabhodhoro emarara, kukuya kumucheto uye makona, uye kuaisa mumipendero yakachengeteka, kuitira kuti igadzire girazi rakaputsika rinenge rakafanana nejecha rechisikigo zvimedu, wobva wazvisanganisa zvakafanana. huwandu hwepende.Uye ipai maitiro uye muenzaniso iyo yapfuura pende yakanga isina.Pendi yerudzi urwu inogona kugadzirwa mumvura inonyungudika pendi yemotokari.Zvinhu zvinoshandisa rudzi urwu rwependi yakasanganiswa tsvina yegirazi zvinogona kuburitsa ratidziro yakapararira kana yaiswa pamagetsi emotokari kana chiedza chezuva, icho chine maitiro maviri ekudzivirira tsaona nekushongedza.

4.Girazi richikuya mkurwara inoshandiswa kugadzira zvigadzirwa zvegirazi ceramics: girazi ceramics yakaoma, ine high mechanical simba, yakanaka kugadzikana kwemakemikari uye kugadzikana kwekupisa.Nekudaro, mutengo wekugadzirwa kwezvinhu zvechinyakare mbishi zvinowanzoshandiswa kune girazi ceramics wakakwira.Munyika dzekunze, kugadzirwa kwemagirazi ekeramics uchishandisa tsvina yegirazi kubva pakuyangarara uye kubhururuka madota kubva kune magetsi pane echinyakare girazi ceramics kwakabudirira.Iyi girazi ceramics inogadzirwa nehunyanzvi nzira yekubatanidza kunyunguduka uye kunyunguduka: kusanganisa nhunzi nemarara girazi, kunyunguduka pa1400 ℃, kugadzira amorphous girazi, kudzima mvura, kukuya, uye kunyura pa810 ~ 850 ℃, inogona kugadzirwa mugirazi. ceramics ine yakanaka mechanical properties, iyo inoshanda kumunda wekuvaka.Vatsvakurudzi veSainzi kubva kuTsinghua University neWuhan University of Technology kuChina vakabudirira kugona tekinoroji yakakosha yekushandisa madota enhunzi, marasha gangue, maindasitiri akasiyana siyana, smelting slag uye Yellow River silt sechinhu chikuru chekugadzira magirazi ekeramics ekushongedza mapaneru.

5. Girazi mosaic inogadzirwa negirazi rinokuya guyo: goya zvakanaka girazi remarara muupfu hwegirazi, wobva wawedzera huwandu hwekunamira, colorant kana decolorant, wozvisanganisa zvakaenzana nemusanganisi.Batch inotsikirirwa mumuviri wegirinhi nenzira yakaoma yekutsikirira, uye iyo yakaomeswa yakasvibira muviri inotumirwa kune roller kiln, pusher kiln kana tunnel kil ine yekupisa tembiricha ye800 ~ 900 ℃ yekunyudza, uye kazhinji inogara munzvimbo yekupisa yekupisa kwe15 ~. 25 maminitsi.Zvigadzirwa zvakatonhodzwa kubva muchoto zvichaongororwa, kusarudzwa, kupetwa, kuomeswa, kuongororwa, kuputirwa, kuchengetwa kana kuendeswa, uye zvigadzirwa zvisina kukodzera zvichashandiswazve.

6. Kugadziriswa uye kugadzirwa kwemafuta ekupisa uye zvigadziriswe zvinonzwika negirazi grinding machine: foam glass imhando yegirazi zvinhu zvine diki diki density, yakakwirira simba, uye izere nediki pores.Chikamu chegasi chinotora 80% - 95% yehuwandu hwehuwandu hwezvigadzirwa.Kuenzaniswa nemamwe inorganic thermal insulation uye ruzha rwekuvharidzira zvinhu, ine zvakanakira yeakanaka thermal insulation uye ruzha rwekudzivirira kuita, kwete hygroscopicity, corrosion resistance, chando kuramba, kusapisa, nyore kubatana uye kugadzirisa."Maitiro ayo ekugadzira ndeyekupwanya tsvina yegirazi, Wedzera calcium carbonate, kabhoni poda - rudzi rweanopupa furo uye furo accelerator, zvisanganise zvakaenzana, zviise muforoma, uye wozviisa muchoto chekupisa.Pasi pemamiriro ekunyorovesa tembiricha, wedzera furo mumiriri kuti uite mabubbles pagirazi, wozogadzira furo girazi.Mushure mokunge girazi rabudiswa muchoto, rinobviswa, rinonyungudutswa, uye rakachekwa kusvika pakukura.

Serudzi rwechishandiso, tsvina yegirazi ndiyo nzira yakanakisa yekudzokorodza huwandu hukuru hwegirazi nekuishandisa mukuvaka.Mhedzisiro yazvino yekutsvagisa yakaratidza kuti zvinogoneka kushandisa tsvina girazi seminerari musanganiswa wekongiri, asi iyo indasitiri yekushandisa haina kuwanikwa nekuda kwehunyanzvi hwekushandisa uye zvimwe zvikonzero.Thegirazikugayainogadzirwa neHCMilling (Guilin Hongcheng) ndicho chishandiso chikuru chinopa maindasitiri ehuwandu kugadzirwa kwegirazi kudzokorodza.Inoshandiswa kugaya girazi, uye inogona kuwana makumi ematani ekubuda paawa yemuchina, uye inogona kugadzira 80-600 mesh girazi poda.Kana uine zvinodiwa zvinodiwa, tapota nyorera E-mail yedu:mkt@hcmilling.comkana kufona pa +86-773-3568321, HCM ichakugadzirira iwe yakanyatsokodzera kugaya chirongwa zvichienderana nezvaunoda, zvimwe zvakawanda ndokumbira utarise. https://www.hc-mill.com/.
