People in the EPC industry know that the drying of coatings in the EPC process will directly affect the efficiency of the factory and the quality of finished products. In order to speed up the drying rate of water-soluble coatings for large molds, a simple EPC drying method in production is to place the coated EPC molds in the sun or in the drying equipment in the EPC drying room below 60 ℃ to speed up the drying
For small moulds produced in batches, most of them use ovens and drying chambers to heat for 4-12h at 50-60 ℃ to accelerate the drying and curing of coatings. Air humidity and flow state during drying are as important as drying time and temperature. The selection of drying equipment in the EPC drying room is very important for the foundry. Let's take a look at the application of EPC drying project in the foundry
In the past, some EPC foundries used steam EPC drying equipment in the EPC drying room. It took about 5 days to dry a single batch of EPC--_ After the G EPC drying dehumidifier and PD series heating, heating, drying and dehumidifying integrated machine are put into use, the single batch drying operation time of EPC can reach 16h. After three times of drying, the technical acceptance personnel of the foundry will weigh and record the lost foam, and then send the lost foam to the drying equipment in the lost foam drying room for drying for up to 4h
After drying, the technicians weighed the lost foam for the second time, and the difference between the weighing value and the first time was not more than 10g, which fully met the requirements of the drying process. While ensuring the drying quality, the drying time was shortened by about 86%, greatly saving the time cost, and creating significant benefits for the factory_ G EPC drying and dehumidifying machine and PD series heating, heating, drying and dehumidifying integrated machine have the characteristics of high efficiency, energy saving, controllable drying process, convenient management and continuous technological innovation:
I. High efficiency, energy saving and environmental protection. The essence of the drying equipment in the EPC drying room is "water removal". 20 kg of water can be separated out per hour, and the moisture removal efficiency is 5 times that of the moisture removal fan. The heating system only needs to maintain the process temperature of 30 ℃ - 45 ℃. The heat loss of the drying equipment in the EPC drying room during the drying process is less than 15%. Therefore, compared with the traditional "open EPC drying room drying equipment", the energy consumption is reduced by more than 35%, and the drying speed is increased by more than 33%
II. The drying process is controllable. The three temperature section low temperature closed drying technology developed according to the coating process can control the temperature and moisture discharge rate. The mold shell has no cracks, the model deformation is small, and the drying quality is high, which can eliminate various quality defects caused by the model's impermeability
For the demand of energy-saving dehumidification and drying in drying rooms and drying rooms, the EPC drying equipment developed and produced by electrical appliances--_ G EPC drying dehumidifier and PD series heating, drying and dehumidifying integrated machine 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 select the electric heating with corresponding power 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!

_ Technical parameters of G EPC drying dehumidifier and PD series heating heating drying dehumidifier:
Model selection of integrated dryer and dehumidifier: select the appropriate model according to the overall humidity load of the actual drying room, specifically, calculate the cooling capacity, dehumidification capacity per unit time and other key data according to its area, floor height, evaporation capacity of drying water, initial humidity value, target humidity value, indoor sealing effect, moisture dissipation source, fresh air supply and other comprehensive factors to correctly select the required model.
