我公司专门根据HDPE双壁波纹管的成型工艺及制品要求和无机刚性粒子增韧理论，选用优质的PE原料为基料，采用超细活性碳酸钙等无机料为主料，并且添加适量的偶联剂、分散剂等通过混炼方式制成的改料粒子，产品分散性好，与管材的基料结合性强，可增强管材的韧性和刚性，并能改善管材的表面光泽度。

采用不含石棉的优质超细滑石粉与聚丙烯树脂混炼而成，具有良好的分散性，添加该母料后，显著提高弯曲模量以及提高尺寸稳定性、提高挤出量，降低配方成本。
It is made of asbestos-free high-quality ultrafine talcum powder mixed with polypropylene resin. It has good dispersion. The addition of this masterbatch significantly increases the flexural modulus as well as dimensional stability, increases extrusion volume and reduces formulation costs.

本设备方案采用内置分级，热风循环强力稀相改性方式，最大程度达到成品的分散和筛余物以及水份的控制，适用于大批量活性轻钙、活性重钙的生产。The equipment solution adopts built-in classification, hot air circulation and strong low concentration coating process to maximize the dispersion of finished products and the reduction of sieve residue and moisture content. It is suitable for the mass production of the surface coating of PCC and GCC.
