can dry to a moisture content below 0.02%, and solves the shortcomings of poor transparency, sprue sticking, bubbles, silver bars, cracks, poor dimensional stability, internal stress, and insufficient product physical strength.
Dehumidification and drying feeding equipment series are composed of: non-heat dehumidification dryer, heat preservation type drying barrel and all stainless steel suction machine. The suction machine can transport the raw materials from the drying barrel to the forming machine, and can also transport the raw materials from the storage barrel to the drying barrel. According to customer needs, a kind of raw material can be delivered to two molding machines, vacuum motors and safety filter dust collectors are installed inside the machine. According to the production needs of different products, we can provide a powder-removing suction machine to separate the powder in the raw material and capture it. This device has a compact structure and is suitable for the production of precision injection products using engineering plastics such as connectors, precision gears, mobile phone communications, digital cameras and product size requirements, so that the moisture content of the raw materials after wet and dry is low and stable, which can meet strict requirements Technical and quality requirements.
Most engineering plastics are hygroscopic. When the plastic is taken out from the moisture-proof sealed packaging bag and exposed to the atmosphere, it will begin to absorb moisture from the atmosphere.
If it is a conventional hot-air barrel dryer, it is Humid external air can dry the plastic, so it cannot prevent the plastic from continuing to absorb moisture.
1. The internal circulation of the dehumidifier: through the operation of the compressor → discharge high-temperature and high-pressure gas through the exhaust port → enter the condenser for cooling → become a low-temperature and high-pressure gas → pass through the capillary tube → become a low-temperature and low-pressure liquid → evaporate and suck through the evaporator Heat → until the compressor becomes a low-temperature and low-pressure gas. So it goes back and forth.
2. The external circulation of the dehumidifier: under normal startup → through the operation of the fan → moist air is sucked in from the air inlet → passes through the evaporator → the evaporator absorbs the moisture in the air on the aluminum sheet → becomes dry air → Pass through the condenser to dissipate heat → blow out from the air outlet.
Energy saving Plastic resin dryer application
The design system of the energy-saving plastic grease counting dryer is more simplified than ordinary dehumidifiers. It not only reduces the power consumption of the system, but also has high efficiency, ultra-energy saving and power saving up to 60%. It is small in size and does not take up space. It is especially suitable for dust-free workshop. No cooling water is required, so it is easy to move. The structure is simple and the machine has high reliability. The whole machine adopts microcomputer control, simple operation, stable performance, lower energy consumption, and dry air volume 30~200m3/hr. In addition, optical-grade energy-saving plastic grease dryers are designed for the production of optical-grade products to meet the different needs of customers. It is caused by insufficient dehumidification of the plastic before molding. Especially high water-soaking plastics such as PET, PBT, PA, PC, etc. require ultra-low dew point Dewpoint-40℃ drying equipment. It can be dried to a moisture content below 0.02%, and solves the shortcomings of poor transparency, sprue sticking, bubbles, silver bars, cracks, poor dimensional stability, internal stress, and insufficient product physical strength. With the widespread use of engineering plastics, Dehumidifying dryers have gradually replaced traditional hot air dryers.
This is a device used to dehumidifying plastic resin to achieve drying. For example,
PC,PC/ABS,PC/PBT,PE.HDEPE,LDPE black3%,PE.HDEPE.LDPE black40%,PEEK,PE(1),
Dehumidifier dryerand other plastic resins must be dehumidified and dried during the production process to improve the quality of the finished product.
Energy saving Plastic resin dryer series are mainly designed for high-efficiency dehumidification of engineering plastics with strong hygroscopicity. Using the honeycomb runner with ceramic fiber as the base material, which represents the highest technological achievements of today, as the core component, the dry air provided can easily reach -40℃ dew point, and ideally it can reach -50℃ or even lower dew point , And the dew point temperature is stable, ensuring the high quality and stability of the molded plastic products. The whole series adopts P.LD. temperature control system as standard equipment; also provides PLC control with LCD touch-sensitive human-machine interface and can monitor the dehumidification effect of the machine Dew point meter is optional, the maximum drying air volume of this product can reach 3000m3/hr. The plastic before molding must be dried to an orientation ratio of less than 0.02%, which is completely bad, sprue adhesion, burrs, bubbles, silver bars, flow marks, cracks, dimensional stability and internal stress. Product defects (for example, insufficient physical properties and strength) are caused by sufficient dehumidification of the plastic before molding. Especially for PET, PBT, PA, PC and other high water absorption plastics, drying equipment with an ultra-low dew point of -40°C is required.
Energy saving Plastic resin dryer can be dried to a volume ratio of less than 0.02%, which solves the shortcomings of short circuit, gate adhesion, bubbles, silver bars, cracks, poor dimensional stability, internal stress and insufficient physical strength of the product. There are a lot more.
Mainly used in plastic products, automobiles, optical discs, experiments, communications, optics, etc.; the rotary honeycomb can reach a low dew point of zero bai for dehumidification and drying at -40°C. In the case of enhanced configuration, the dehumidification dew point can be as high as -50°C. It is a choice for high-precision industries.
Energy saving Plastic resin dryer Precautions
1. The desiccant dryer should be cleaned frequently and kept clean. The dehumidifier should be placed in the center of the room. The air inlet and outlet of the refrigerated dryer should not be blocked by obstructions, and the air filter should be cleaned. When the ambient temperature is lower than 15℃, the water droplets attached to the evaporator surface will freeze and the dehumidifier effect will be weakened. If the ambient temperature exceeds 40℃, the pressure in the system will increase and the compressor will overload. At this time, the overload protector The circuit should be cut off, otherwise the compressor motor will be damaged. So the best temperature range for dehumidifier is 15℃~40℃. If the humidity in the air is below 30%, it will be too dry and uncomfortable, so a reliable humidity controller will control it to maintain the range of 50% to 60%. When in use, close doors and windows as much as possible to achieve dehumidification in the room. The body of the desiccant dryer must be placed flat, not tilted or turned sideways, to avoid machine failure or abnormal noise. 2. The water storage in the desiccant dryer is too full. In order to avoid overflowing and contaminating the ground, when the machine body must be moved during operation, please unplug the power cord first, and then pour out the water in the water storage bucket. After moving the dehumidifier, it is best to put it statically for four to six hours before starting to use it. Because the compressor pipeline in the dehumidifier contains cold coal, it must take four to six hours to return the cold coal to its original position after being moved. 3. Clean the air filter regularly (about once every two weeks) to maintain the dehumidification and dust removal efficiency and life of the machine. Clean the air filter and wash it with water below 40°C; it is better to clean it with detergent. After washing off the dust, rinse it with water, dry it in the shade and put it back into the body. When cleaning the body, wipe it gently with a damp cloth; avoid directly splashing water for cleaning, so as not to damage the electrical insulation. Adhesives on the surface of the body can be cleaned with soap and water. Avoid spraying with gasoline, petroleum spirit, solvent or spray insecticide to avoid peeling paint or discoloration. Do not use thin rods or iron wires to dig out the inside of the machine to avoid malfunction or danger. Please unplug the power cord to maintain the life of the machine when it is out of power, not used for a long time, or when traveling.
