Why do we use dehumidifiers in our daily life?

　　In people's daily life, it is precisely because air humidity affects human health. Pay attention not only to temperature and rain, but also to humidity changes in the air. On the premise of mastering the laws of four seasons (generally high humidity in spring and summer, low humidity in autumn and winter), be good at adjusting the indoor air humidity. For example, less windows should be opened in rainy or foggy days in summer to prevent excessive indoor humidity; When the weather is clear after rain and the temperature rises, pay attention to ventilation and lighting to keep the room humidity

　　It is better to use heating equipment with humidification function, and the range is appropriate. When heating indoors in winter. If not, you can also humidify yourself. For example, sprinkle some water or bake some damp things on the indoor ground to increase the humidity.

　　Dryers are generally known as dehumidifiers, industrial dehumidifiers and household dehumidifiers. It must be unknown that there is another kind of machine called dehumidifier dryer, which is widely used in the plastic processing industry. How can it dehumidify and dry?

　　The engineering plastics with strong hygroscopicity have been proved to be widely used in the plastic processing industry due to the impact of climatic conditions. Radical hot air drying system cannot be used to effectively reduce its moisture content, and three machine integrated dehumidification dryer must be used before molding

　　The sensitivity of some resins or macromolecules is very high. 2 The drying efficiency is particularly important for precision injection molding manufacturers. If the drying time is too long, stress may be generated, resulting in scorching, embrittlement and discoloration of parts. The vacuum dryer changes the adverse effects caused by the uncertainty of drying, thus greatly reducing the waste rate.

　　The main control parameter for rapid evaporation of water in raw materials to achieve rapid drying is vacuum degree. 3 Vacuum drying principle Vacuum drying is based on the principle of reducing the evaporation point of water at low pressure. The vacuum dryer and dehumidification dryer are tested together, and the results show that the vacuum dryer can save 70% - 80% energy consumption. This is mainly because the desiccant of the desiccant dryer needs to consume a lot of energy in the regeneration process. Vacuum drying

　　It will cause thermal chemical and physical reactions of raw materials. The drying time is usually 1/5 – 1/6 of that of other dehumidification drying. The quality of materials will be reduced, such as discoloration and melt index, which will affect the quality of waste products. The vacuum dryer shortens the drying time of materials, thereby reducing the possibility of material quality decline. Take PC drying as an example, drying at 120 ℃, before reaching 0.02% of final water content

　　Dehumidifying and drying usually takes about 4 hours. Vacuum drying only takes 20-25 minutes to complete. In this way, the drying time of 3 hours and 35 minutes is saved. The application of the vacuum dryer in the mold testing section is particularly advantageous!
