Artificial marble microwave curing equipment

Microwave curing artificial marble is fast curing it by microwave radiation. More conventional curing speed, good uniformity, energy saving, has been in a number of man-made marble materials companies. Good effect. Microwave is the frequency at 300 megahertz to 300 gigahertz electromagnetic waves. Media material from the polar molecules (water molecules) and non-polar molecules, in the electromagnetic field, these polar molecules from a random distribution of the original steering arrangement according to the orientation of the electric field polarity. In the role of high-frequency electromagnetic field, these orientations by an alternating electromagnetic field changes, movement and mutual friction effect of this process resulted in the molecule (in the 2054 MHz electromagnetic field, the water molecules per second for 2.4 billion five thousand million times the displacement), resulting in heat. In this case the alternating electromagnetic field field kinetic energy into heat within the media, the media temperature rising. Microwave heating is the heated object itself becomes the heat generator, heating whole call, the process does not require thermal conduction, and therefore can achieve uniform heating in a short time. This feature allows the thermally conductive material with poor heat-dried in a short time, the energy utilization rate is improved, can also make the size of the furnace is smaller than a conventional heating furnace. Meanwhile, when the material in the microwave electromagnetic field, the material overall temperature rise. At this time, since the material surface water evaporation, resulting in the surface temperature is reduced; causing an outer low in the high temperature gradient, the gradient directions exactly in line with the direction of water evaporation. So very efficient. Microwave drying applications, there are two ways. First, the conventional tunnel-drying equipment, mainly used in the drying temperature is less demanding, process no volatile substances in the dried material (which can be dried to a moisture content of 0.1 percent in a matter of a few to ten minutes time, temperature It can be controlled within 100 degrees; the other is vacuum microwave drying method (static gondola microwave vacuum drying equipment and dynamic stirring microwave vacuum drying equipment), mainly used in drying heat-sensitive materials and volatile materials drying microwave equipment can be widely used for iron ore classes (limonite, magnetite, hematite, ilmenite, vanadium-titanium magnetite, ferrous sulfide, pyrrhotite, pyrite, pentlandite iron ore, pyrite magnets, etc.), copper class (chalcopyrite, bornite, tetrahedrite, copper oxide, copper oxide), manganese ore type (soft manganese ore, manganese black, brown manganese ore, manganese carbonate, etc.) , quick-drying lead-antimony ore classes (galena, lead antimony ore sulfur catalyst, etc.) Bauxite (such as diaspore, a boehmite, gibbsite), and other minerals.
