Basic Magnesium Carbonate plays a vital role in the country’s PVC plastics industry. The following is a detailed description of its role:
First, Enhancement of PVC plastic properties
Enhance the physical properties:
Basic magnesium carbonate can be used as a reinforcing agent for PVC plastics to significantly enhance its physical properties such as tensile strength, tear strength and hardness. By improving the internal structure of the plastic, magnesium carbonate alkali can also improve the impact resistance and abrasion resistance of PVC plastic, making it more durable.
Improve heat resistance:
The addition of basic magnesium carbonate can significantly increase the heat resistance temperature of PVC plastics, allowing them to maintain stable performance in high-temperature environments. This is particularly important for PVC plastic products that need to withstand high temperature environments (such as wire and cable sheathing, automotive interior parts, etc.).
Flame retardant properties:
As a non-halogenated flame retardant, magnesium alkali carbonate is characterized by low smoke, low toxicity and efficient flame retardancy. Adding magnesium carbonate in PVC plastic can significantly improve its flame retardant properties and reduce the risk of fire.
Second, optimize PVC plastic processing
Improve processing performance: magnesium carbonate has good dispersibility and fluidity, can be evenly dispersed in the PVC plastic matrix. This helps to reduce the viscosity of PVC plastic, improve its processing performance and make the processing smoother.
Regulating the melting behavior of plastics: By adding the right amount of magnesium carbonate base, the melting temperature and melting rate of PVC plastics can be regulated. This helps to optimize the molding process of PVC plastics and improve the precision and consistency of the products.
Third, environmental protection and sustainability
Environmentally friendly material: basic magnesium carbonate is a natural, non-toxic, biodegradable material. Adding magnesium basic carbonate to PVC plastics helps to reduce the reliance on traditional fillers and reduce environmental pollution.
Resource recycling: magnesium basic carbonate has good recyclability and reuse. In the recycling process of PVC plastics, basic magnesium carbonate can be effectively separated and reused, which helps to realize the recycling of resources and sustainable development.
