PVC tubular mill powder is a common plastic material made of polyvinyl chloride (PVC). In order to further improve its performance and meet specific needs, different modification technology methods can be employed.
1. Add plasticizers:
The addition of plasticizers is a common method to improve the properties of PVC tubular mills. Plasticizers can improve the flexibility and ductility of PVC tubular mill powders, and improve their processability. Commonly used plasticizers include phthalates and epoxy plasticizers. By adding the right amount of plasticizer, the PVC tubular mill powder can be made more durable and easy to process during use.
Second, the application of fillers:
The addition of filler is another common method of modification of PVC tubular mill. Fillers can be inorganic fillers or organic fillers, such as calcium carbonates, silicates, glass fibers, etc. The addition of filler can increase the hardness, strength and heat resistance of PVC tubular grinding powder, and improve its mechanical properties. In addition, fillers can also reduce costs and improve the stability and reliability of the product.
3. Add stabilizer:
PVC tubular mill is susceptible to factors such as thermal decomposition, oxidation and ultraviolet radiation during processing and use. To improve its stability, a stabilizer can be added. Commonly used stabilizers include organotin salts, lead salts, and calcium-zinc salts. These stabilizers can effectively inhibit the thermal decomposition and oxidation reaction of PVC tubular mill, prolong its service life and improve product quality.
Fourth, blending modification:
Compounding is a method of mixing PVC tubular mill powder with other plastics or additives to improve its properties. By blending with other plastics, the hardness, toughness, impact resistance and other properties of PVC tubular grinding powder can be adjusted. Commonly used blending materials include acrylonitrile-butadiene rubber (NBR), polyethylene (PE), etc. Compounding can be designed and optimized for a better combination of performance based on specific needs.
