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.
keusik keramik pinuh dipaké pikeun nyieun keusik coated, sarta dipaké deui sababaraha kali sanggeus reclamation, nu éféktif bisa ngaronjatkeun kualitas sarta efisiensi produksi castings, ngurangan laju kerok castings jeung ongkos produksi usaha, biaya pamakéan jangka panjang leuwih handap éta. tina pasir silika.

Kauntungan
● Résin coated keusik keramik jeung résistansi suhu super tinggi, lalawanan kuat ka inténsitas deformasi, inflasi low, évolusi gas low, pikeun minuhan sarat husus konsumén.
● Alus fluidity keusikan pangabisa, non-iteuk kapang, lumaku pikeun prosés inti-nyieun jieunan.
● résistansi suhu Super luhur bisa nyingkahan ka casting defects kayaning keusik ngaduruk, permukaan melu, veining, flash gabungan sarta retakan.
● Small than 100kg castings could be achieved without sand coating.
