无机填料的加入可以改善材料的动态和热力学性能，包括刚度、抗蠕变、热变形温度、收缩等，但另一方面，无机填料的存在通常会降低材料的抗拉强度和韧性。无机填料对材料力学性能的影响主要取决于无机刚性颗粒的形状、粒径、粒径、颗粒表面特性和聚合物基体性能。以下小系列介绍了常用无机填料在增强增韧聚合物中的应用。碳酸钙在增强增韧聚丙烯中的应用碳酸钙产品分为重质碳酸钙和轻质碳酸钙。重质碳酸钙是重质钙的简称，简称GCC，是一种直接机械粉碎天然方解石、石灰石、白炭黑、贝壳等的方法。由于重质碳酸钙的沉降量小于轻质碳酸钙，因此称之为重质碳酸钙。目前，重质碳酸钙的工业生产主要有两种方法，一种是干法，另一种是湿法。与湿法相比，干法生产成本更低、用途广泛的产品。轻质碳酸钙是轻质钙的简称，又称沉淀碳酸钙，英文简称PCC，是石灰石等原材料锻造而成，以生产石灰为主要成分的氧化钙和二氧化碳，然后用水消化石灰乳，以生产石灰乳为主要成分的氢氧化钙，然后将石灰乳碳化成二氧化碳，生成碳酸钙沉淀，最后经脱水、干燥和粉碎。或者，碳酸钙沉淀由碳酸钠和氯化钙的复合反应产生，然后将其脱水、干燥和粉碎

Polypropylene Spunbond FabricMFI 45 ppRaw Material

The addition of inorganic fillers can improve the dynamic and thermodynamic properties of the material, including stiffness, creep resistance, thermal deformation temperature, shrinkage, etc., but on the other hand, the presence of inorganic fillers often reduces the tensile strength and toughness of the material. The influence of inorganic fillers on material mechanics performance mainly depends on the shape of inorganic rigid particles, particle size, particle size, particle surface characteristics and polymer substrate performance. The following small series describes the application of commonly used inorganic fillers in reinforced toughening polymers. Application of calcium carbonate in enhanced toughened polypropylene Calcium carbonate products are divided into heavy calcium carbonate and light calcium carbonate. Heavy calcium carbonate is short for heavy calcium, short for GCC, is a mechanical method to directly crush natural calcite, limestone, white to, shell and so on. Because the settling volume of heavy calcium carbonate is smaller than that of light calcium carbonate, it is called heavy calcium carbonate. At present, there are two main processes for industrial production of heavy calcium carbonate, one is dry and the other is wet. Dry processes produce lower-cost, versatile products compared to wet methods. Light calcium carbonate is short for light calcium, also known as precipitation calcium carbonate, English for short for PCC, is limestone and other raw materials forged to produce lime main components of calcium oxide and carbon dioxide, and then water digestion lime milk to produce lime milk main components of calcium hydroxide, and then into carbon dioxide carbonized lime milk to produce calcium carbonate precipitation, and finally by dehydration, drying and crushing. Alternatively, calcium carbonate precipitation is produced by a compounding reaction of sodium carbonate and calcium chloride, which is then dehydrated, dried and crushed.
