A PU-PVC production line is a type of equipment used to produce polyurethane and polyvinyl chloride (PVC). Polyurethane is an important polymer material with excellent physical and chemical properties, which is widely used in construction, automobiles, furniture, footwear, coatings, adhesives and other fields. PVC is a kind of fire-resistant, corrosion-resistant material, often used in wire and cable, building materials, plastic pipes and other industries.
PU-PVC production line can be divided into the following steps: raw material treatment, mixing, separation, molding, curing, cutting, etc.
First, raw material treatment. PU-PVC production line requires the use of a variety of raw materials, including polymers, plasticizers, stabilizers, fillers and so on. These raw materials need to be treated, such as filtration, drying, grinding, etc., to ensure the quality of raw materials.
Second, mix. Put the treated raw materials into the mixer, and mix the raw materials fully and evenly by rotating stirring. During the mixing process, pigments and hardeners can be added as needed to change the performance and appearance of the product.
Then, separate. The mixed raw materials need to be separated by an extruder. The extruder heats the raw material to a molten state and then extrudes it through a mold to form the desired product shape. During the separation process, parameters such as temperature, pressure and speed of the extruder can be adjusted to control the quality and size of the product.
Then, shape. Through the collaboration of the mold and extruder, the molten raw material is extruded to form the desired product shape. The molded product can be sheet, pipe, film, etc., the specific shape and size depend on the design and needs of the product.
Again, curing. The molded product needs to undergo a curing process in order to form a stable structure and physical properties. The method of curing can be natural curing, or it can be carried out by heating, radiation and other ways.
Back, cut. After the cured product is cooled and treated, it needs to be cut to the desired size and length. Cutting can be done using tools, cutting machines and other equipment.
These are the main steps of the PU-PVC production line. In actual production, it is also necessary to consider the procurement and storage of raw materials, equipment maintenance and maintenance and other aspects of the problem. The operation of the PU-PVC production line requires efficient production management and quality control to ensure that the product meets the requirements and market demand.
