The crystal is applied to the papermaking that can raise whiteness and non - transparency , remains - proportion of the crystal is higher than the usual light calcium carbonate . as for plastics , it can improve impact strength in the plastics , its inhibiting - burning capability is advancing bigger than the common inhibiting - burning material of magnesium hydroxide . concerning the thermo tropic adhesives , the physical property of compound - packing is higher than the one of single - packing , namely remover strength , softening point , hardness , climate tolerance and the speed of consolidation are high 晶须作为造纸填料，可使纸张的白度和不透明度提高，留着率比造纸常用填料轻质碳酸钙高；用作塑料填料，可使塑料的冲击强度提高，阻燃性能比常用阻燃材料氢氧化镁有较大的提高；添加到热熔型胶粘剂中，与轻质碳酸钙混合使用可明显提高热熔胶的剥离强度、软化点、硬度、耐侯性以及固化速度。
In order to improve the mechanical properties of frp , the coupling agent kh - 570 is added to strength adhesive of surface of the reinforcements , the results indicate that the bending strength of the specimen reach to the original level and the impact property of the specimen is also improved 根据抗静电阻燃树脂体系的粘度、凝胶时间,确定了rtm工艺参数,并以该工艺成功制备出frp包装箱,其抗静电性能、阻燃性能及力学性能能够满足作为武器装备包装箱的特殊贮运要求。
