Hezhou calcium carbonate is widely used in the plastics industry The following is a detailed analysis of the application of Hezhou calcium carbonate in the plastics industry:
I. Application of Hezhou calcium carbonate as a plastic filler
-
Plasticizing effect ：
-
Calcium carbonate, as a filler in plastics such as polyvinyl chloride (PVC), can increase the capacity of plastics, reduce costs, and make the fabric more uniform.
-
In rigid PVC, the amount of calcium carbonate added can reach 5% 20% (in PVC doors and windows, profiles, plates, pipes, and sheets), and as high as 40% in floor tiles 80%.
-
-
Improve processing and physical properties ：
-
Adding calcium carbonate can improve the processing properties of plastics, such as wear resistance, tensile strength, impact strength, bending strength, elongation at break, and thermal properties.
-
Calcium carbonate can also improve the stability of plastic products.
-
-
Substitute white pigment ：
-
Because the whiteness of calcium carbonate is above 90%, it can replace expensive white pigments and play a certain whitening role.
-
II. Specific application fields of Hezhou calcium carbonate in the plastics industry
-
Plastic bags, water pipes, and tableware ：
-
After calcium carbonate is processed into masterbatch, it becomes an important raw material for plastic bags, water pipes, tableware, and other products.
-
-
Biodegradable plastics field ：
-
Hezhou's calcium carbonate industry also supports the biodegradable plastics field, helping to reduce white pollution. For example, Guangxi Yunhe New Materials Technology Co., Ltd. fully mixes high-quality local Hezhou calcium carbonate and resin to produce degradable materials with lower costs and better performance than those of its peers.
-
III. Development trend of Hezhou calcium carbonate industry
-
Industry chain extension ：
-
Hezhou City is seizing development opportunities, building an industrial cluster with core technological competitiveness and product advantages, and promoting the extension of the calcium carbonate industry chain to downstream terminal product manufacturing.
-
-
Environmental protection and sustainable development ：
-
With the increasing awareness of environmental protection, the Hezhou calcium carbonate industry is also continuously exploring the path of environmental protection and sustainable development. For example, some companies use new technologies to convert dust and exhaust gas from the production process within the shed to reduce environmental impact.
-
In summary, Hezhou calcium carbonate has a wide range of applications in the plastics industry, and with the development of the calcium carbonate industry and technological advancements, its application fields will continue to expand.
