This paper study on the effects of PAM on improving water stableaggregate and reducing nutrients loss from sandy soil, methods of Laboratory incubation and leaching were adopted.
Results show that simple composition and stable properties of W oxide is a prerequisite for quality WC powder with uniform particle size and less aggregate.
结果表明:保证原料氧化钨相成分单一和性能稳定是生产粒度均匀、聚团少的优质WC粉的前提;
