樹脂覆膜陶瓷砂

Sintered ceramic sand is an artificial spherical casting sand developed by SHXK. It has high refractoriness (>1800°C), small angular coefficient (<1.1, approximately spherical), low acid consumption (neutral material), low binder content (30% reduction in binder content), and particles high strength, non-breaking and other characteristics, suitable for sand casting (molding sand, core sand), coated sand, V method casting, lost foam casting (filled sand), foundry coating (ceramic sand powder), 3D printing and other casting processes. It is green and environmentally friendly foundry sand.

型砂、芯砂中採用部分陶粒砂，使殼型、殼芯具有耐高溫、低膨脹、易塌陷、發氣量低的性能，可有效防止鑄件的膨脹缺陷。對於形狀特別複雜的型芯，可以解決射砂不易壓實的問題。

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。
