Extrusion molding is one of the more common plastic molding methods, which is to melt plasticize the plastic, through the head of the extruder at the mouth gap of the mold to form a profile similar to the shape of the mold. It is suitable for all thermoplastics and some thermosets, and can be used to form various plastic pipes, bars, plates, wires and cables and special-shaped section profiles, etc., and can also be used for plastic coloring, material making and blending.
Because most engineering plastics have hygroscopicity, coupled with the influence of weather and regional climate, it is easy to cause excessive moisture of plastic particles and cannot achieve the molding effect. In addition, plastic raw materials are different in the front granulation process, so the gas moisture content and moisture absorption are also different, so during molding, it is easy to produce bubbles, silver bars, poor transparency, cracks, poor stability and other problems, seriously affecting product quality. The air pipeline of the dehumidification dryer adopts a closed circulation system, which can not be affected by the external weather, whether it is dry weather or wet weather, the material can be dried well, no moisture, and the product molding quality is high.
The presence of plastic moisture will usually have a harmful effect on the performance of plastics and molding processing, and water will vaporize at high temperatures, so that products produce bubbles, spray marks, surface silver filaments and other defects, so plastic moisture content is an important factor affecting the processing technology of plastics, product appearance and product characteristics, drying links can not be ignored.
The dew point of the dehumidifier can reach -70 °C, shorten the drying time, improve the drying efficiency, and the residual moisture content can be less than 20ppm.
Domestic dryer with SCADA technology, remote control, adjustment of technical parameters according to the actual situation, online detection, and prediction of faults in advance.
Dew point switching technology can set different dew points according to the drying requirements of different materials, minimizing energy consumption.
Compared with the same output of honeycomb dehumidifier, Jinyue molecular sieve dehumidifier saves 18%-60% in energy consumption. (This is based on thousands of experimental reports and feedback from customers, testing real data)
Compared with the Jinyue standard molecular sieve dehumidifier, the Jinyue modular dehumidification dryer saves about 25% energy consumption.
