Application of Light Calcium Carbonate In Plastics Industry
Light calcium carbonate can be dispersed in the plastic matrix as a filler, which can limit the movement of the plastic molecular chain, thereby increasing the rigidity and hardness of the plastic. In addition, the thermal stability of light calcium carbonate is good, which can improve the heat resistance of plastics to a certain extent and reduce the deformation and degradation of plastics in high temperature environments. At the same time, calcium carbonate can also absorb ultraviolet light, improve the weather resistance of plastic products, extend its service life .
Light calcium carbonate has high hardness and rigidity, which can enhance the mechanical properties of plastics when added to plastics. In polypropylene (PP), polyethylene (PE) and other plastics to add an appropriate amount of light calcium carbonate, can improve the hardness of plastic products, compressive strength and deformation resistance, make plastic products more durable, such as PP plastic auto parts made of light calcium carbonate, can better withstand mechanical stress and external impact.
In the plastic processing process, the right amount of light calcium carbonate can improve the flow of plastics. It can play a lubricating role between plastic particles, reduce the friction between particles, make plastic in extrusion, injection molding and other processing processes easier to flow, fill the mold cavity more smoothly, improve processing efficiency and product quality, reduce processing energy consumption.
