plastic PVC Granulation Machine
Product Description
- Definition
PVC granulation is a process in which polyvinyl chloride (PVC) resin is mixed with various additives such as plasticizers, stabilizers, lubricants, and fillers in a certain proportion. Through processes such as heating, plasticization, and extrusion, it is made into granular products with a certain shape and particle size.
Raw Materials
• PVC Resin: It is the main raw material. There are different types such as suspension method and emulsion method. Suspension method resin is widely used.
• Additives: Plasticizers can improve flexibility, such as phthalates; stabilizers can prevent PVC degradation, like lead salts and organotin; lubricants reduce friction, such as stearic acid and its salts; fillers reduce costs and improve performance, such as calcium carbonate.
Main Equipment
• Mixing Equipment: Such as high - speed mixers, which are used to uniformly mix the raw materials.
• Extrusion Equipment: Single - screw or twin - screw extruders are used to complete plasticization and extrusion.
• Pelletizing Equipment: There are air - cooled die - face pelletizers, underwater pelletizers, etc., which cut the extruded strips into granules.
Process Flow
• Ingredient Preparation: Weigh each raw material accurately according to the formula and put them into the mixer.
• Mixing: In the high - speed mixer, the raw materials are fully and uniformly mixed to form a premix.
• Plasticization and Extrusion: The premix enters the extruder. Under the action of heating and screw shearing, it is plasticized into a uniform melt and extruded from the die head.
• Pelletizing: After the extruded melt is cooled, it is cut into granules by the pelletizer.
• Screening and Packaging: Screen the granules to remove unqualified ones, and then pack the qualified granules into storage.
Applications
PVC granulation products are widely used in many fields such as pipes, profiles, wires and cables, films, artificial leather, plastic doors and windows, shoe soles, etc. They can meet the requirements of different applications for the performance and processing technology of PVC materials.
Advantages
• High Customizability: By adjusting the formula and process, granules with different properties can be produced.
• Convenient for Transportation and Storage: Granular products are easy to load, unload, transport, and store for a long time.
• High Processing Efficiency: The granules can be quickly plasticized and formed in subsequent processing, improving production efficiency.
