Plastic recycling extruder machine is one of the most important pieces of equipment in the dây chuyền tái chế màng thải, which changes the physical properties of plastics through high-temperature melting, plasticizing, and extruding.
The total amount and types of energy distribution in China show obvious geographical differences, and the demand for energy in plastic recycling extruder machine is very large. Since plastics require high temperatures, the cost of energy consumption in the plastic pelletizing industry is very high.
Now the plastic recycling extruder machine on the market has formed a pattern of electromagnetic heating as the main, ceramic heating and iron heating as a supplement.
Electromagnetic heating for plastic recycling extruder machine
In recent years, the electromagnetic heating for plastic recycling extruder machine has been widely promoted in the country. The electromagnetic heater is based on the basic principle of electromagnetic induction so that the cylinder itself is hot, so the heating rate is faster than in other ways.
In addition, there is a heat preservation material encapsulated on the cylinder of the plastic recycling extruder machine, so that the thermal kinetic energy is not easy to flow out into the air, which makes the thermal kinetic energy to be utilized flexibly, greatly reduces the thermal damage, and improves the use of thermal efficiency.
Thuận lợi
- Energy saving: rapid heating, real-time accurate temperature control. Rapid warming can be as high as 600 degrees or more, energy saving up to 70%, which helps to improve the output of waste film recycling machine and reduce the wear and tear of the equipment.
- Intelligent and safe: the use of electromagnetic induction heating can make the surface temperature of waste film recycling machine lower. The human body can touch it safely, avoiding the occurrence of burns and scalding accidents caused by traditional heating methods. It protects the production safety of employees.
- Long life, maintenance-free: the traditional electric heating coil heating method is to use resistance wire heating, resistance wire in the long term in the high temperature of the harsh environment will oxidize and thus cause a reduction in its service life. The barrel screw body heat and the heater itself does not heat and is made of insulating materials and high-temperature wire winding, so long life and no maintenance.
- Environmental protection: heat loss is very low, improving the working environment, in line with the requirements of environmental protection and energy saving.
- High degree of intelligence: it can realize long-distance monitoring and data line control, with multi-charging protection and fault self-diagnosis alarm function.
Ceramic heating for waste film recycling machine
Ceramic heating is commonly used in plastic film granulator, i.e., the heating wire is passed inside the ceramic and wrapped into a circle to be packed on the barrel of the machine. The electric heating ring is energized to generate heat and conduct heat through the ceramic so that the temperature of the screw rises to achieve the effect of melting plastic.
Thuận lợi
- The ceramic electric heating ring is not easy to damage, safe to use.
- Ceramic electric heating ring output power is high, the heating speed is fast. If the temperature must be increased, the necessary temperature can be reached quickly (fast heating and the friction temperature generated by the rotation of the extruder screw can achieve a stronger saving effect).
- It is a clean, effective, and easy-to-control heating method.
Iron heating for plastic film granulator
Some plastic recycling extruder machines are heated by iron. The electric heating wire and metal casing are filled with dense heat-conducting material, and the mouth of the tube is sealed with a high-temperature sealing material. High mechanical strength, easy to use, and safe. Moreover, the iron material is corrosion-resistant and has a long service life.
