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.
採用全陶砂製作覆膜砂，再生後可重複使用，可有效提高鑄件品質及生產效率，降低鑄件報廢率，降低企業生產成本，長期使用成本低於矽砂。因此，近年來，幾乎所有大型覆膜砂廠都採用陶瓷砂作為原砂來生產覆膜砂。
優勢
● 樹脂覆膜陶粒砂具有超耐高溫、抗變形強度強、低膨脹、低發氣量，符合客戶的特殊要求。
● 流動性填充能力好，不沾模，適用於人工製芯工藝。
● 超強的耐高溫性能，可避免燒砂、表面褶皺、脈紋、接縫飛邊、裂紋等鑄造缺陷。
● Small than 100kg castings could be achieved without sand coating.
