Spherical Ceramic Sand ye Foundry

Tsanangudzo Pfupi

Foundry Ceramic Sand, nehunyanzvi inodaidzwa se "Sintered Ceramic Sand for Foundry", yakanzi zvakare ceramsite, cerabeads, ceramcast, yakanaka yekugadzira yakatenderera yezviyo chimiro inogadzirwa kubva kucalcined bauxite.Iyo huru yemukati ndeye aluminium oxide uye Silicon oxide.Ceramic jecha, ine zvivakwa zviri nani pane iyo silica jecha kuti iwane kuita kurinani mukuwana.Iyo ine yakakwira refractoriness, kudiki kuwedzeredza kwemafuta, yakanaka angular coefficient, yakanakisa kuyerera, Kukwirisa kuramba kupfeka, kupwanya uye kupisa kwekushisa, yakakwirira reclamation rate.

Advantage

● Jecha reGreen.YAKANAKA kune zvakatipoteredza kana ichienzaniswa nesilica (silicosis) uye zircon jecha
● High refractoriness (>1800°C), inogona kushandiswa kukanda zvinhu zvakasiyana-siyana.Iko hakuna zvakare kudikanwa kwekushandisa akasiyana mhando yejecha maererano nezvinhu.
● High reclamation rate.Zvese zviri zviviri Thermal uye mechanical reclamation.Inopa hupenyu hurefu hwebasa uye kuderedza kushandiswa kwejecha.
● High collapsibility.Sintered Ceramic sand spherical shape kana ichienzaniswa neangular shaped tsanga inobvumira kupatsanurwa kuri nyore kubva kunhengo dzakakandwa uye nekunatsiridza kudonha kunokonzeresa kuderera kwezvimedu uye kugona kukanda.
● Kuyerera kwakanakisa uye kushanda zvakanaka kwekuzadza nekuda kwekutenderera.
● Lower Thermal kuwedzera uye Thermal Conductivity.Zviyero zvekukanda zvakanyanya uye yakaderera conductivity inopa zvirinani mold kuita.
● Kuderera kwehuwandu hwakawanda.Sezvo artificial ceramic jecha rinenge hafu yakareruka sejecha receramic rakasanganiswa (jecha dema rebhora), zircon uye chromite, rinogona kubuda zvakapetwa kaviri nhamba yezviumbwa pahuremu hweyuniti.Inogona zvakare kubatwa zviri nyore, kuchengetedza vashandi uye kutamisa simba mari.Nekudaro, kutariswa kunofanirwa kupihwa kune huwandu hwekuwedzera binder.
● Inoda 40-50% shoma resin.
● Matanda anonamira zvishoma kana kuti asina.
● Inogona kushandiswa sejecha rimwe chete.
● Kugovera kwakagadzikana.Kwegore kugona 200,000 MT kuchengetedza kukurumidza uye kugadzikana kwekupa.

Application

Sechinhu chisina kwazvakarerekera, KAIST ceramic jecha rinoshanda kune acid uye alkali resins.

Inogona kushandiswa zvakanyanya kugadzira simbi yakakandwa, simbi yakakandwa uye nonferrous simbi kukanda, sekurasika furo kukanda, jecha rakavharwa, jecha resin, bhokisi rinotonhora repakati, kukanda chaiko, uye kudhinda kwe3D.

Zvikamu zveParticle size Distribution

Iyo particle size yekugovera inogona kugadzirwa zvinoenderana nezvaunoda.
