UV PVC Board Marble Sheet

The main components and structural analysis of PVC marble slabs are as follows:

1. **Polyvinyl chloride (PVC) resin**: As a substrate, it occupies the main part of the plate. PVC is a thermoplastic polymer material with good mechanical properties, chemical corrosion resistance and electrical insulation.

Two. **Stabilizer**: In order to improve the stability of PVC in processing and use, lead salts, calcium zinc or other organic tin stabilizers will be added to prevent the material from decomposing or discoloration when heated.

3. **Plasticizer**: Add phthalates or other environmentally friendly plasticizers to increase the flexibility of the material, make PVC sheets easier to process and bend, and improve low-temperature brittleness.

Four. **Filler**: Calcium carbonate (CaCO3) is commonly used as a filler, which can reduce costs, increase the dimensional stability of the plate, and improve certain physical properties.

5. **Lubricant**: In order to improve the processing fluidity and reduce equipment wear, an appropriate amount of internal and external lubricant will be added.

6. **Pigments and texture agents**: used to simulate the color and texture of natural marble, including organic or inorganic pigments, as well as special texture-making technologies, such as transfer printing or spraying processes, to make the surface of PVC sheets have a realistic marble effect.

7. **Ultraviolet absorbers and antioxidants**: These additives will be added to improve the weather resistance of outdoor use and prevent materials from aging due to ultraviolet irradiation.

In summary, PVC marble slabs are made by mixing PVC resin with a variety of additives in a specific proportion, and processed by extrusion, rolling or lamination and other processes, aiming to imitate the appearance and certain physical properties of natural marble, while taking advantage of the processing convenience and cost advantages of PVC materials.
