The desiccant dryer is used in the plastic processing industry, where the product has shrinkage, silver streaks, bubbles, cracks, flow marks, poor transparency, etc. The main reason for these poor quality is that the plastic has not been fully dried before it is molded. As a result, engineering plastics such as PA, PET, PC, PBT, CA and other materials with strong hygroscopicity, due to the penetration of water into the plastic particles, traditional hot air dryers cannot completely dry it. Practice has proved that reducing the dew point of the drying wind to below -40℃ and controlling the heat to blow it over the surface of the moisture-containing plastic particles can reduce the moisture content of it to below 0.02% before molding. The three-in-one dehumidification dryer is airtight. The air is fully dehumidified and heated in the circulatory system. The dry air quickly separates the moisture in the plastic pellets to achieve the effect of dehumidification and drying. The moisture and heat generated by the dehumidification dryer in the process mainly pass through the high temperature on the equipment The air duct is exhausted, and many customers are entangled about what kind of air duct is the exhaust duct of the dehumidification dryer? Which high temperature air duct is good for the dehumidification dryer? The following Hangzhou Haikuo editor will introduce you in detail.
   The hot air pipe of the desiccant dryer is used to discharge the hot air of the dryer, and the inner wall is smooth. The hoses currently on the market are divided into high temperature vulcanization and room temperature vulcanization. High temperature vulcanization is a production process that has been changed in recent years. In 2015, it was only able to produce high temperature resistant air ducts that were vulcanized at room temperature. With the renewal of technology and the improvement of production equipment, for this orange-red high temperature resistant hose, the quality produced can completely replace imported hoses, and its excellent quality is not worse than imported air pipes. This kind of silicone high temperature air duct is covered with silicone glass fiber cloth and supported by spiral steel wire inside. The silicone glass cloth adheres to the upper and lower layers of the steel wire to strengthen adhesion and tension. Double-layer pipe wall, leak-proof, smooth inner wall, high temperature resistance, acid and alkali resistance.

What kind of high temperature air duct is better for    dehumidification dryer?
   The most commonly used in the market is a red high temperature resistant air duct with white fiber threads on the surface. This air duct can withstand high temperatures up to 350 degrees, covered with a silicone fiberglass cloth and spiral steel wire inside. Support, silicone glass cloth bonding the upper and lower layers of the steel wire to strengthen adhesion and tension.
   Double-layer pipe wall, leak-proof, smooth inner wall, high temperature resistance, acid and alkali resistance. The high-temperature exhaust pipe of the dehumidifier dryer is not only used for the dehumidifier dryer, but also can be used for ventilation, extracting smoke, humidity and dust, etc., and extracting high temperature and humid gas. It is used to guide hot and cold air, granular desiccant used in plastics industry, dust removal and extraction plant, heating exhaust, blast heater exhaust and welding gas exhaust, high-temperature gas exhaust.
   When choosing the hot air duct of the desiccant dryer, there are two conventional ones: one is the high temperature air duct through room wet vulcanization. This process has been used for several years. At present, some factories also use this Its disadvantages are poor environmental protection and poor temperature resistance and aging resistance. The hot air pipe of the dehumidification dryer produced by Hangzhou Haikuo adopts high-temperature vulcanization process. The pipe produced by this process is environmentally friendly and non-toxic, has a shiny surface without burr particles, and has a higher temperature resistance and aging resistance. Therefore, when choosing a dehumidification dryer When choosing high temperature air duct, this kind of high temperature vulcanized silicone air duct should be selected.
