Mchenga wagolide wopangira mchenga

Kufotokozera Kwachidule:

Foundry Ceramic Sand, mwaukadaulo wotchedwa "Sintered Ceramic Sand for Foundry", yemwenso amatchedwa ceramsite, ceramcast, yemweyo ndi cerabeads, mayiko ena amatchedwanso Golden Sand, ndi wabwino kupanga ozungulira njere mawonekedwe amene amapangidwa kuchokera calcined bauxite .Zomwe zili mkati mwake ndi aluminium oxide ndi Silicon oxide.Mchenga wa Ceramic, uli ndi zinthu zabwino kwambiri kuposa mchenga wa silika kuti ugwire bwino ntchito poyambira.Ili ndi refractoriness yayikulu, kukulitsa pang'ono kwamafuta, kokwanira bwino kwa angular, kuyenda bwino kwambiri, Kukana kwambiri kuvala, kuphwanya ndi kugwedezeka kwamafuta, kutsika kwamphamvu kwambiri.

Ubwino

Mchenga wa Kaist ceramic foundry sand ndi pafupifupi theka lowala ngati zircon ndi chromite, ndi pafupifupi wachitatu wopepuka ngati mchenga wosakanikirana wa ceramic.Poyerekeza ndi izi mchenga zachilengedwe ndi zina foundry TV (zakuthupi amatha kutembenukira pafupifupi kawiri chiwerengero cha zisamere pachakudya pa unit kulemera).Mchenga wa Kaist ceramic foundry ukhoza kupulumutsa nkhungu ndi ma phukusi oyambira okhala ndi maubwino angapo omwe amaphatikiza ma phukusi opangira mchenga wolimba kwambiri, wokhala ndi kukana kutentha kwambiri, kutsika kwamafuta pang'ono, kusinthika kwa gawo lomaliza komanso kutha kwapamwamba.Itha kuchitidwanso mosavuta, kupulumutsa ntchito ndi ndalama zosinthira mphamvu.Komabe, wopanga amalimbikitsa kulabadira kuchuluka kwa binder kuwonjezera.

Kugwiritsa ntchito

Monga zinthu zosalowerera ndale, mchenga wa ceramic wa KAIST umagwira ntchito pazitsulo za asidi ndi alkali.

Itha kugwiritsidwa ntchito kwambiri popanga chitsulo, chitsulo choponyedwa ndi zitsulo zopanda chitsulo, monga kuponya thovu lotayika, mchenga wokutidwa, mchenga wa utomoni, bokosi lozizira pachimake, kuponyera mwatsatanetsatane, ndi kusindikiza kwa 3D.

Kugwiritsa ntchito
