PPS casting film longitudinal stretching equipment is a type of equipment used for producing polypropylene melt casting films, which has the characteristics of high efficiency, stability, and reliability. This article will provide a detailed introduction to the equipment principle, workflow, main components, and application fields.
The PPS casting film longitudinal stretching equipment is used to heat and melt polypropylene particles, and then extrude the molten polypropylene into a thin film through an extruder. After cooling, stretching, and other processes, high-quality polypropylene casting films are finally formed. Throughout the entire process, the equipment achieves precise control of the membrane material by controlling parameters such as temperature, speed, and stretching ratio, thereby obtaining the ideal product.
2、 Workflow
1. Raw material treatment: Pre treat polypropylene particles, including drying, screening, etc., to ensure the quality and purity of the raw materials.
2. Melt extrusion: The pre treated polypropylene particles are added to the extruder, and through heating and screw rotation, the particles are melted into molten polypropylene, which is then extruded into a thin film through the die head of the extruder.
3. Cooling: The extruded molten polypropylene film is cooled through a cooling roller to quickly cool and solidify.
4. Longitudinal stretching: The cooled polypropylene film is stretched through a longitudinal stretching mechanism to change the molecular structure and arrangement of the film material, thereby improving its strength and transparency.
5. Winding: The stretched polypropylene film is wound through a winding mechanism to form a reel shaped finished film material.
3、 Main components
1. Extruder: responsible for heating and melting polypropylene particles, and extruding the molten polypropylene into a thin film through the die head of the extruder.
2. Cooling system: including cooling rollers and cooling water system, used to quickly cool and solidify the extruded molten polypropylene film.
3. Stretching mechanism: The cooled polypropylene film is stretched through a longitudinal stretching mechanism, changing the molecular structure and arrangement of the film material, and improving the strength and transparency of the film material.
4. Winding mechanism: The stretched polypropylene film is wound through the winding mechanism to form a reel shaped finished film material.
5. Control system: Accurately control the entire production process by controlling parameters such as temperature, speed, and stretching ratio.
4、 Application field
