What is a Dehumidifier?
To remove water vapor from the air, dehumidifiers are electrical appliances that use either adsorption onto a desiccant material or condensation. They are frequently used in homes and offices to regulate humidity levels, prevent mold and mildew growth, and in industrial settings to protect sensitive equipment from corrosion.
Dehumidifying Agents for Plastics
Desiccants or dehumidifying agents effectively remove moisture from plastics, which can negatively impact their properties by reducing strength and increasing brittleness. Manufacturers commonly use the following dehumidifying agents for this purpose:
- Silica gel: This highly effective desiccant absorbs moisture from the air and traps it inside its pores. Manufacturers commonly use small packets of silica gel that can be placed inside plastic containers or bags to keep the contents dry.
- Molecular sieves: Synthetic materials with a high capacity for water absorption. Manufacturers frequently use them in the production of plastics to remove moisture before molding or extrusion.
- Calcium oxide: Also known as quicklime, this strong desiccant effectively removes moisture from plastics and is commonly used in the form of small pellets or powder.
- Bentonite clay: A natural mineral with a high capacity for water absorption. Manufacturers often use it in the production of plastics to remove moisture before molding or extrusion.
- Zeolites: A type of mineral with a high surface area and unique structure that makes them effective at removing moisture from plastics. Manufacturers commonly use them in the form of small pellets or powder.
Manufacturers can directly add these dehumidifying agents to plastic pellets or use them during the production process to remove moisture before molding or extrusion. Alternatively, they can place them inside plastic containers or bags to keep their contents dry.
Physical Principles of Dehumidification
Understanding the physical principles of dehumidification is crucial in selecting the appropriate dehumidifier for plastic material, which can ultimately determine the success or failure of the manufacturing process. Dehumidifiers remove water vapor from the air through a process called adsorption. Adsorption occurs when water molecules are attracted to and adhere to the surface of another material.
For adsorption to occur, there must be a molecular exchange between the water vapor and the surface of the material. Industrial dehumidifiers commonly use silica gel, a highly porous material with a large surface area, for adsorption. Silica gel can adsorb a significant amount of water vapor.
Another material that can be used for adsorption is activated carbon, which has even more pores than silica gel and can adsorb even more water vapor. However, activated carbon is less effective at lower relative humidity (below 60%). Dehumidifiers function by circulating air over an adsorbent material.
As the air passes over the material, the water vapor in the air is attracted to and adheres to the surface of the material. The dry air is then recirculated back into the room or space being dehumidified.
Types of Dehumidifiers for Plastics
You have a few options to choose from if you want to keep your plastic items in good condition with a dehumidifier. Desiccant dehumidifiers are the most common types of dehumidifier for plastic material, which draw moisture out of the air by using an absorbent material. It is very effective at reducing humidity levels and can be used in homes, offices, and warehouses.
It is also possible to use a refrigerant dehumidifier, which uses coils and Freon gas to remove moisture from the air. However, these dehumidifiers aren’t as effective in high-humidity environments as desiccant models. If you need a powerful dehumidifier for commercial or industrial use, a refrigerant model is your best option.
Hybrid dehumidifiers combine desiccant and refrigerant technology to offer the best of both worlds. These units are more expensive than either type alone, but they offer the best power and efficiency.
Capacity
Depending on the size of the room, the humidity level, and the temperature, a dehumidifier’s capacity can be measured in pints per 24 hours. A dehumidifier for plastic material should take into account the size of the room and the humidity level when choosing one. A small room will require a smaller unit with a lower capacity, while a large room will require a larger unit with a higher capacity. A high humidity level will also affect the unit’s capacity; for example, a very humid room will require a larger unit.
Airflow
If you have a lot of plastic products in your home, you need to ensure that there is adequate airflow so that they can dry properly, otherwise, they may become warped and misshapen. To ensure proper airflow for your plastics, you can do many things. You can place them in an open area so that air can circulate them. Another way is to use a fan to help circulate air. Finally, you can purchase a plastic-specific dehumidifier.
You should choose a dehumidifier with adjustable airflow settings if you decide to use one. Therefore, you can adjust the amount of airflow according to your specific needs. It is also important to empty the water reservoir frequently so that it does not overfill and cause problems with operation.
Process Integration
Integrating a dehumidifier into plastic processing is essential to achieving the desired results. There are a few key things to keep in mind:
- Depending on the type of plastic you are working with, you will need to maintain a certain level of humidity.
- Your operation’s size and scale will also affect the size and capacity of your dehumidifier.
- To effectively remove moisture from your process, consider the location of your dehumidifier with your other equipment.
With these factors in mind, you can choose a dehumidifier for plastic material that will help you achieve superior results with your plastic processing.
Humidity Sensors and Controllers
If you work with plastic processing or storage, you know that moisture poses a threat. Excessive moisture in the air can cause the plastic to warp, crack, or become brittle. That is why selecting the appropriate dehumidifier is important.
Any dehumidification system must have humidity sensors and controllers as vital components. They aid in maintaining the ideal relative humidity (RH) level for your specific application. With numerous types of humidity sensors and controllers available, it is important to pick one that suits your particular system
When choosing a humidity sensor or controller, you should consider several factors, including the type of plastic you process or store, the necessary temperature and RH range, the size of the area that requires dehumidification, and your budget.
Identifying the Right Dehumidifier for Your Needs
A few key factors need to be taken into consideration when choosing a dehumidifier for plastic material.
- The first is the size of the unit. It’s important to choose a dehumidifier that’s appropriately sized for the space you’re trying to treat. An insufficiently sized unit will not be effective. An oversized unit will be less energy efficient and likely to cause condensation.
It is also important to consider humidity control when choosing a dehumidifier. Dehumidifiers with adjustable humidistats allow you to adjust humidity levels to suit your needs. Plastic can be warped and distorted if it has too much humidity, but it can be brittle and easily broken if it has too little humidity.
- The second consideration is humidity control. You need to select a dehumidifier with an adjustable humidistat so you can dial in the perfect level of humidity for your needs. If the plastic is too humid, it may warp and distort, while if it is too dry, the plastic can become brittle and susceptible to breaking.
- The third consideration is air circulation. Dehumidifiers work by drawing air across a cooling coil. This process also circulates the air in the room, which is beneficial for preventing mold and mildew growth. In enclosed spaces, you must ensure the dehumidifier has an exhaust port to vent moist air.
- Finally, Consider special features such as automatic shut-offs, filters, or remote control operations that may be important to you. These features can make using a dehumidifier easier and more convenient.
