This result has been applied successfully to roll thinner and high porosity strip when the powder has poor fluidity.
此结果在使用流动性较差的粉末，轧制孔隙度高和较薄的带材时，获得了良好的应用。
Due to the great hardness and poor fluidity of plastics, this technology can only make the surface hardness of a product grade HB, failing to meet the actual requirements of application.
由于塑料硬度越高，流动性越差。因此采用此种工艺，制品表面的硬度只能达到HB级，无法满足实际使用需要。
Closed pore perlite overcome traditional expansion perlite bibulous rate and low strength of large, fluidity, and the characteristics of the poor, outspread expansion perlite application fields.
闭孔珍珠岩克服了传统膨胀珍珠岩吸水率大、强度低、流动性差的特点，延伸了膨胀珍珠岩的应用领域。
