Microwave ceramics, porcelain, ceramics and other materials dry porous
    Hunan GuoGuang Ceramic Group Co., Ltd.. Ceramics designed a microwave rapid drying molding production lines for the actual production, proved, the provincial traditional chain drying line, compared to more than 10% increase in billet, strip time from 35-45min shortened to 5-8min, Use the number of mold pieces falling from the whole 100-120 400-500 pieces, saving a lot of plaster molds, and the secondary lines with the use of fast-drying, for 10.5in (1in = 2.54cm) under dry flat total cost can be reduced 350 Yuan / ten thousand.
    Microwave drying technology for complex shapes dried porcelain, and compared to conventional steam drying method, productivity can be increased 24-30 fold increase yield of 15% -35%, the same production area of ​​the original process is only 1 / 20 or so, can greatly improve economic efficiency. This building and sanitary ceramics, tiles and some other special-shaped products, dry for reference.
    Forming a porous ceramic containing more moisture, pores, and the inner hole of the wall of the blank book, using traditional methods due to uneven heating, very difficult to dry and the poor thermal conductivity of the porous material, if the drying process is controlled, easily deformed, the impact porosity and specific surface area. Microwave drying of porous ceramic body can be easily put the water from the 18% -25% to 3%, to shorten the drying time and improved yield. Tang Bamboo study new experiment, honeycomb ceramic body during the drying process, the organic binder to solidify the microwave, shrinkage, and the ceramic honeycomb body to form a network structure, the ceramic honeycomb body stresses and defects that exist within and fixed to obtain a dispersion . Ceramic honeycomb body itself and absorb microwave energy to generate heat. Able to quickly stabilize dry.
    Shukang Tai and other studies have shown that microwave drying evenly, fast, stable and sanitary ceramics drying, drying time shorter than the conventional method more than seven times. Microwave drying washing mask that 80% of the water in the heating phase is excluded, and the higher the moisture content in a rib-shaped portion is preferentially dried in the drying process.
Li Yushu high plasticity clay and glial plasticity drowning poor sandy soil as raw materials for the experimental study of microwave drying. In order to prevent boiling of the water body in the machine, the sample surface temperature in the range of 60-70 c, the microwave power was set 2.5kw, each heated intermittently l0min - times, each heating time of 5-10 s (experiments to determine the optimum range). Experimental results show that the microwave drying method can be mounted so that drying of the colloidal properties of different clay and sandy clay sample specimens.
