求翻译：碳酸钙是无机填料，与聚丙烯的相容性较差，所以在使用前需进行活化处理，以提高碳酸钙与聚合物分子链的结合力，提高填充聚丙烯材料的力学性能。是什么意思？

Calcium carbonate is the poor compatibility of the inorganic filler, and polypropylene, the need for activation treatment before use in order to enhance the binding of calcium carbonate and the polymer chains to improve the mechanical properties of filled polypropylene materials.

Calcium carbonate is a inorganic filler, and the compatibility of polypropylene is poor, so you need to use for adaptive processing to enhance calcium carbonate and polymer molecules linked together to improve competitiveness of mechanics filled polypropylene material performance.

The calcium carbonate is the inorganic padding, is bad with the polypropylene compatibility, therefore must carry on activation processing before the use, enhances the calcium carbonate and the polymer member chain binding force, enhances the packing polypropylene material mechanics performance.

Calcium carbonate is the inorganic filler, and poor compatibility of polypropylene, so needs to be activated before use, to improve the adhesion of calcium carbonate and the polymer chains, improving the mechanical properties of polypropylene material.
