白云质凹凸棒石黏土综合开发应用研究

Research on Multipurpose Exploitation & Utilization of Dolomitic Attapulgite Clay

河南省镇平白云质凹凸棒石黏土通过表面改性处理 ,分别进行了软质透明聚氯乙烯 (PVC)薄膜填料、聚氯乙烯人造革填料、绿醇酸调和漆填料和釉面砖胚体料的应用试验 ,结果表明 ,该矿与改性轻钙填料的效果相当 ,有些指标还超过轻钙 ,完全可替代表面改性轻钙填料。作为原料 ,该土也可用于制造日用精瓷具 ,具有烧成温度低、原料成本降低的特点。

With the base of surface modification conducted on the Dolomitic attapulgite clay from Zhenping County,Henan provence,the clay was applied in the stuffing of plastic, oil paint and embryo component of glaze bricks, respectively. The experimental results were very satisfying. Attapulgite clay with surface modification could replace the modified light calcium carbonate widely used at present as the stuffing.To make the fine porcelain with this attapulgite clay as the raw material has low sinter temperature and low cost.
