The raw material for the PVC Board Extrusion Line is PVC high-density polyethylene plastic, which is a high-crystallinity, non-polar thermoplastic resin.The original PVC is milky white, and it is semi-transparent in a slight section. PVC has excellent resistance to most living and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidants, aromatic hydrocarbons and halogenated hydrocarbons. The polymer is non-hygroscopic and has good water vapor resistance and can be used for packaging purposes. PVC has good electrical properties, especially high dielectric strength, making it suitable for wire and cable. Medium to high molecular weight grades have excellent impact resistance, both at ambient temperatures and even at low temperatures of -40F. The connection end of the PVC pipe shall be marked according to the length of the insertion, and the entire outer circumference of the pipe joint shall be scraped.
For the products produced by the machine from PVC Skirting Board Extrusion Machine Supplier, the scraping length should not be less than the marking size. After the scraping is completed, it should be marked twice. The welding parameters of the electrofusion joint should meet the requirements of the pipe and pipe fitting manufacturer. After the pipe is inserted into the pipe fitting, it should be inspected according to the mark. , confirm that the insertion is in place.
