The continuous downlink of standby further genralrlization and product price, traditional microwave drying line by external energy active mode of heating is
Through not having economy, meanwhile, there is also the potential risks such as microwave leakage for microwave equipment, will for the professional standards of operating personnel
It asks comparison high, is unfavorable for large-scale promotion application.Moreover, using the continuous drying molding mode of traditional microwave, general ceramic honey comb
The too fast reduction of moisture content of green body, less than 2% when being exported to equipment, green body is excessively dry, can not carry out green body cutting, and
It to wait until just carry out cutting processing after firing porcelainization, after ceramic honey comb porcelain, the increase of intensity is to cutting equipment
Blade requires higher, increases cutting difficulty, improves processing cost.
