SYNTHESIS OF TUNGSTEN CARBIDE CERAMICS COATING RESEARCH THE STUDY OF WASTEWATER TREATMENT CHEMICALS

提出了一种制备碳化钨陶瓷的新方法-钨酸三乙醇胺浸渍热分解法。研究表明,用该法可成功制得碳化钨涂层材料。经过综合热分析仪的测定可得出,碳化钨生成温度为954.5℃。通过碳化钨的X射线衍射(XRD)分析可知,该工艺合成的碳化钨主要成份为W_2C。将所制备的碳化钨陶瓷作电极电解含甲胺磷的农药废水。实验证明,在电压为30V,电流为0.03A时,随着通电时间的加长,有机磷转化为无机磷的程度随之增大。当电解时间为165min时,有机磷的转化率可达9.8%,高于同等条件下碳电极的1.6%。

This paper introduces a new type of ceramic materials prepared new method of tungsten carbide - tungsten acid decomposition method since Triethanolamine. Studies have shown that the method can be successful with a tungsten carbide material system. After a comprehensive analysis of the determination of heat can be drawn the WC to the tenprerature 954.5℃ . Through the tungsten X-ray diffraction （XRD） analysis shows that the synthesis process for the major components of the tungsten carbide W2C. Preparation of tungsten carbide to the catalytic electrode for electrolysis wastewater containing pesticide methamidophos. Experiments show that, In the voltage of 30V, when the current is 0.03A, With the power of the extended time, Organic phosphorus into inorganic phosphorus increases the degree. When the electrolysis time at 165min, Organic phosphorus conversion rate up to 9.8%. higher than The rate of carbon electrode under the same conditions （1.6%）.
