The advantage of high frequency heating characteristics

Date:2019-01-27 10:34:42 hits: 【Fontsize:B M S
1, fast heating, high efficiency. High frequency heating medium from internal overall heating difference with conventional heat transfer heating mode. Practice has proved that if the workpiece thickness less than 20 mm, the heat conduction time is usually 1 min/mm, greater than the thickness of heat conduction time will greatly extend; On the influence of high frequency heating workpiece thickness is much smaller. The thicker the artifacts, the advantages of high frequency heating, the more obvious.
2, heating uniformity is good. Is due to electric field through heating, electromagnetic field uniform temperature of the object, the object a heating part of the inside and outside temperature can effectively enhance the glue curing strength, improve the quality of the product.
3, high frequency heating with heating selectivity. Because under a certain frequency, the loss factor of all kinds of material is different, have different absorption energy of electric field. The choice of appropriate frequency can make under electric field with a certain material heating, greatly improve the heating efficiency, reducing energy consumption. Such as wood makeup, to glue line heating and wood not only heat (see chart).
4, strong controllability is more adapted to the automatic production, small occupied area, low labor intensity. High-frequency heating power is hot, stop heating power. Heating effect could be controlled by heating time is convenient. High-frequency heating of the automation and high precision control form can be easily and effectively join factory production equipment, forms a shape can make the factory assembly line.
5, environmental protection, no dust, no smoke, no heat radiation, safety and health.
