People come into contact with plastic almost every day, so what exactly is plastic?
The plastic commonly used is not a single component; it is made up of many materials. Among them polymer polymer (or synthetic resin) is the main component of plastic, in addition, in order to improve the performance of plastic, but also add a variety of auxiliary materials in polymer compounds, such as filler, plasticizer, lubricant, stabilizer, colorant, antistatic agent, etc., to become a plastic with good performance.
There are many kinds of plastics and their uses vary. For example, polyethylene, good electrical insulation, chemical corrosion resistance, cold resistance, non-toxic, it can be made into film, as food, drug packaging materials, daily supplies, insulation materials, pipelines, etc.; And polyvinyl chloride, the electrical insulation is good, chemical corrosion resistance, organic solvent resistance, wear resistance, but poor thermal stability, poor air permeability, cold hardening, it can be made into film, hose, daily supplies, pipes, insulation materials, film can not be used to package food; Polypropylene has good mechanical strength, good electrical insulation, chemical corrosion resistance, light weight, non-toxic, but poor oil resistance, low temperature brittle, easy aging, it can be made into film, daily supplies, pipes, packaging materials, etc.; Polystyrene electrical insulation, good light transmittance, chemical corrosion resistance, non-toxic, hard and brittle at room temperature, soft at higher temperature, poor oil resistance, it can be made into high-frequency insulation materials, television, radar parts, medical and health appliances, but also can be made into foam used for shock, moisture, sound insulation, packaging pad material; Urea-formaldehyde plastic has good insulation, heat resistance, waterproof, easy to color, can be made into electrical equipment, automotive parts, daily supplies, etc. Polytetrafluoroethylene resistance to low temperature, high temperature, chemical corrosion, solvent resistance, good electrical insulation, but difficult processing, it can be made into electrical, aviation, chemistry, medicine, freezing and other industrial corrosion resistance, high temperature, low temperature products.
Plastic products in the production of raw materials are to be first produced into plastic particles and then extrusion production, that is to say, the raw material of extrusion plastic products is plastic particles. The quality of plastic particles directly affects the quality of plastic products. When we produce plastic products, we should adjust the raw material formula of particles according to the situation of products. Before the production of plastic particles, the raw materials in the formula should be mixed together and mixed evenly with a blender. After all raw materials are mixed evenly, the plastic pellet machine can be used for particle production. Plastic granule machine is a kind of plastic extruder, should first before we production equipment for heating, when the temperature of the equipment to we can start the equipment after the set temperature and filling materials to the plastic extrusion machine feeding system, plastic extruder can be idle, so after the boot device must fill in the feeding system of raw materials.
Raw materials through the feed system into the screw tubes after plasticizing temperature rise, and the screw on the shear and compression, mixing and so on a series of processing after processing in the plastic granule machine die extrusion into multiple cylindrical strip, the strip after water cooling again by tractors to its delivery to the cutting machine for cutting, so plastic particles has been completed. There are many kinds of plastic particles production process, we want to choose the most suitable particle production process for the quality and type of particles.
