Why should we use dehumidifier and dew point in injection molding industry?
The traditional hot air blower can not prevent the plastic from absorbing moisture, and the drying effect is poor.The use of desiccant dryer can be divided into stand-alone and centralized. The single stand dehumidifier usually includes dryer, main machine, drying barrel and suction machine. Single type dryer is suitable for a variety of drying, the utility model has the advantages of high efficiency and fast drying, convenient refueling.Centralized dehumidifying dryer includes a host and a plurality of dryer drying barrels, each drying barrel heating controller independently, can also dry a number of different materials, and with the air flow control valve to control the volume of each drying barrel, suitable for mass production of plastics.Dorosin dehumidifier is widely used in offices, archives and information, library, computer room, instrument room, hospital of precision and valuables storage, chemical, pharmaceutical, military, glass, food, electronics, metallurgy, printing, warehouse, underground room, record room, electric power, telecommunications, tobacco, medicine, printing, tea, leather, textile demand a place of humidity.In the process of use, can help to eliminate all kinds of losses caused by moisture, so that product production and preservation can be carried out in the appropriate humidity, so as to ensure and control the quality of products.Please inquire dorosin official website
Because most of the engineering plastics have moisture absorption, coupled with weather and regional climate impact, it will easily lead to excessive moisture particles, can not reach the molding effect. In addition to some plastic raw materials in different granulation process, the gas moisture content and moisture absorption is different, so in the molding, easy to have a bubble, silver, poor transparency, cracks, poor stability problem, seriously affect the quality of products. Dehumidification dryer air line is closed loop system, can be free from outside weather, regardless of dry weather or wet weather can dry the material, not anti tide, high quality product molding.Is the first dryer in air pumping in removal of moisture in the air in the low dew point, and then air dry after heating into one or more standard drying hopper, can improve the drying efficiency and shorten drying time. If it is to the traditional hot air, with air moisture to dry material, it is difficult to achieve the drying effect. In addition, when the plastic is taken out of the moisture proof packing bag and exposed to the atmosphere, it will begin to absorb moisture from the atmosphere.
Because humidity is too large, dehumidifier is needed to reduce humidity.The dew point is to make the air in the water can condense into water temperature, the working principle of the dehumidifier is the air sucked into the machine, the air temperature drops below dew point temperature, the moisture in the air condenses into water and the air separation, so as to achieve the purpose of air drying.
