Ceramsite sand is an artificial spherical casting sand developed by SHXK, same with Japanese Cerabeads. It has high refractoriness (>1800°C), small angular coefficient (<1.1, approximately spherical), low acid consumption (neutral material), low binder content (at least 30% reduction in binder content), and particles high strength, non-breaking and other excellent characteristics, suitable for all types of sand foundry, especially for the coated sand. There are more successful application cases.
wedhi Keramik Full digunakake kanggo nggawe wedhi ditutupi, lan dienggo maneh bola-bali sawise reclamation, kang bisa èfèktif nambah kualitas lan efficiency produksi castings, ngurangi tingkat scrape castings lan biaya produksi Enterprises, biaya nggunakake long-term luwih murah tinimbang sing. pasir silika. Mulane, ing taun-taun pungkasan, meh kabeh tanduran pasir sing dilapisi skala gedhe nggunakake pasir keramik minangka pasir mentah kanggo ngasilake pasir sing dilapisi.
Kaluwihan
● Resin ditutupi wedhi keramik karo resistance suhu super dhuwur, resistance kuwat kanggo kakiyatan ewah-ewahan bentuk, inflasi kurang, évolusi gas kurang, kanggo ketemu syarat khusus pelanggan.
● Kemampuan ngisi fluiditas sing apik, cetakan non-stick, ditrapake kanggo proses nggawe inti buatan.
● Super resistance suhu dhuwur bisa supaya casting cacat kayata kobong wedhi, lumahing melu, veining, lampu kilat peserta lan kokain.
● Small than 100kg castings could be achieved without sand coating.
