EPC drying dehumidifier product introduction: in the current casting industry, EPC technology is advanced, practical and stable; With the continuous improvement of environmental protection requirements, EPC, as a new process without environmental pollution, has been widely recognized by more and more foundry manufacturers and has been put into use in large quantities. However, drying is the most complicated process in the EPC process. The white mold should be painted after drying, and one layer should be dried once. In the process of production and use, how to dry EPC and reduce production costs has become the main topic of research
In the prior art, if the lost foam is dried in the air, the drying time is too long, and it needs to be taken out from the painting equipment one by one to hang again. The working efficiency is low. However, the drying method is adopted. Due to the unreasonable structural design of the drying equipment, the drying of each part is uneven, the drying degree is different, and the drying time is long. EPC process: First, the foam plastic model is manufactured, and the outer surface is coated with paint. After drying in the EPC drying chamber, the molten steel is cast to form a casting
At present, during the drying process of EPC models, the moisture in the outer surface coating evaporates to the drying room in the form of water vapor, which leads to the increase of the humidity in the EPC drying room and the sharp decline of the drying efficiency, seriously affecting the economic benefits of manufacturers. To solve this problem, foundry manufacturers often take the following two measures in the EPC drying room:
, When the humidity in the EPC drying room decreases to a certain extent, turn off the humidity exhaust fan and the window, and cycle in turn; However, the disadvantage of such measures is that the atmospheric air contains some water. In rainy and humid weather, the relative humidity even reaches 90% - 100% RH, which not only fails to reduce humidity, but also has a reaction
2. industrial dehumidifier is added to the EPC drying room: when the humidity in the EPC drying room reaches a certain value, the moisture in the air is removed by the industrial dehumidifier to reduce the humidity; However, the disadvantage of industrial dehumidifiers is that the manufacturing cost of industrial dehumidifiers is relatively higher than that of dehumidifiers. When the air temperature in the EPC drying room reaches below 38 ℃, ordinary industrial dehumidifiers will shut down due to high temperature protection, which is very easy to be damaged, and their service life will be greatly reduced, increasing the use cost of manufacturers
_ G lost foam drying dehumidifier and PD series heating, drying and dehumidifying integrated machine (applicable to dehumidification in the environment where the indoor temperature is higher than 38 ℃ but lower than 55 ℃) can not only quickly remove the moisture in the drying room, effectively control the humidity in the drying room during the whole drying process, but also can select the corresponding power of electric heating to assist in temperature rise, so as to greatly accelerate the drying speed, effectively improve the utilization rate of the drying room and the drying quality! Welcome to inquire the details of EPC dryer and dehumidifier_ Technical parameters of G EPC drying dehumidifier and PD series heating heating drying dehumidifier:
, Fresh air supply and other comprehensive factors can be used to calculate the cooling capacity, dehumidification capacity per unit time and other key data before the correct selection of the required model. For more details about the EPC dryer dehumidifier, please refer to:
Hangzhou Zhengdao Electrical Equipment Co., Ltd; And use_ After G lost foam drying dehumidifier and PD series heating drying dehumidifier, the humidity in the drying room can be rapidly reduced without exhausting heat; Now, it only takes 16 or 12 hours to achieve the original 24-hour drying effect, greatly reducing the operating cost of the drying room. It has been widely used in drying rooms of factories and enterprises all over the country, and its effect has been recognized by all users
To sum up, traditional EPC drying methods and drying equipment are generally simple, incomplete drying, low drying efficiency, and uncontrollable temperature and humidity, resulting in the unsatisfactory effect of EPC in the casting process and low yield of castings. Moreover, it is not environmentally friendly and energy consumption is high_ G EPC drying dehumidifier and PD series heating drying dehumidifier are the only choice to change the EPC drying mode, improve the deep drying efficiency of EPC and effectively volatilize residual foaming agent
_ G EPC drying dehumidifier and PD series heating heating drying dehumidifier can quickly remove moisture during EPC drying, effectively reducing the humidity of drying room; Generally, the humidity in the drying room should be controlled at about 30% RH; At the same time, ensure that the temperature in the drying room is about 50 ℃, so that the drying rate of the lost foam can be increased by about 25%, the speed of the hot air sent in is faster, the turbulence effect in the room is increased, and the lost foam can be dried evenly, effectively preventing the coating cracking problem.
