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.

Honeycomb dehumidifier dryer application
Plastic dehumidifiers are mainly suitable for underground engineering, national defense engineering, archives, libraries, factory workshops, warehouses, computer rooms, and environments that require temperature and humidity. The temperature-adjustable dehumidifier can automatically adjust temperature, cool down and dehumidify. The temperature-adjustable dehumidifier integrates dehumidification and refrigeration functions with adjustable cooling capacity, which is especially suitable for dehumidifying places in high temperature and high humidity environments with large thermal load changes. The unit automatically runs in the cold air dehumidification mode, and the heat generated by the unit is dissipated into the outdoor atmosphere through the outdoor unit; in the low temperature, cold and humid environment, the unit automatically runs in dehumidification conditions. The cooling dehumidifier has a refrigeration function while reducing humidity, but the refrigeration function is not adjustable. It is suitable for dehumidification occasions with large heat load and no relative humidity requirements.

Dehumidifier dryerand other plastic resins must be dehumidified and dried during the production process to improve the quality of the finished product.
Honeycomb dehumidifier 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.
Honeycomb dehumidifier 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.
Honeycomb dehumidifier dryer Precautions
1. Under normal circumstances, the dehumidifier should be placed in the center, leaving enough space around, and the air inlet and outlet of the dehumidifier should not be covered by obstacles to keep the air unblocked.
2. Do not pull the power cord of the dehumidifier forcefully to move the dehumidifier during use.
3. When using the dehumidifier, the airtightness of the room should be good, otherwise, the dehumidification effect will not be obvious, and it will increase the load of the dehumidifier and affect the service life of the dehumidifier.
4. At present, most dehumidifiers on the market are equipped with computer automatic control systems, with four-speed fuzzy control gears. Except for the first gear when shutting down, they have suitable humidity (relative humidity: 70%-60%) and dry (relative humidity: 60%-50%) and continuous dehumidification (relative humidity: the lowest can reach 35%). When the indoor humidity is higher than the humidity of the corresponding selected gear, the machine will automatically start dehumidification; when the water tank is full, the machine will automatically stop working, and The water level indicator light is on to remind that the water tank is full, and the water must be poured out before the machine can operate again.
5. When the machine body must be moved, unplug the power cord first, and then pour out the water in the water storage bucket. After moving the dehumidifier, it is best to let it stand for 4 to 6 hours before turning it on. Because the compressor pipeline of the dehumidifier contains refrigerant, after being moved, the refrigerant can only return to its original position after a period of time.
