Detailed description of the invention
Microwave heating principle is to convert electrical energy into microwave energy, makes the molecule of heating object strenuous exercise and collision occur and generate heat by microwave.Material medium is made up of polar molecule and nonpolar molecule, and under electromagnetic field effect, these polar molecules transfer to according to direction of an electric field and carry out orientations from random distribution state; And under microwave electromagnetic field action, these orientation movements constantly change with the frequency of billions of times per second, cause strenuous exercise and the collision friction of molecule, thereby produce heat, reach electric energy and be converted into the heat energy in medium.Visible, heating using microwave is dielectric material own loss electric field energy and generating heat.And the dielectric constant of different medium material and dielectric loss angle tangent are different, therefore the fuel factor under microwave electromagnetic field action is also different.The material of being organized by polar molecule, can absorb microwave energy preferably.Hydrone is extremely strong polarity, is the best medium that absorbs microwave, so the goods and materials of all moisture molecules must absorb microwave.Another kind ofly form them by nonpolar molecule and substantially do not absorb or seldom absorb microwave, this class material has polytetrafluoroethylene (PTFE), polypropylene, polyethylene, polysulfones etc., plastic products and glass, pottery etc., and it can see through microwave, and does not absorb microwave.This class material can be used as container or the support that heating using microwave is used, and does encapsulant.
As follows by microwave heating method heating object advantage: firing rate is fast.Conventional heating (as flame, hot blast, electric heating, steam etc.) is all to utilize hot conduction, convection current, heat radiation first heat to be passed to the surface of heating object, then is conducted and progressively made central temperature rising (both normal external heat claiming) by heat.It will make centre reach required temperature, needs certain heat conduction time, and just longer to the required time of the poor object of pyroconductivity.Heating using microwave belongs to inner mode of heating, and electromagnetic energy directly acts on medium molecule and converts heat to, and transmission makes to be heated inside and outside medium simultaneously, does not need heat conduction, therefore can reach at short notice homogeneous heating.Homogeneous heating.While heating by external heat mode, for improving firing rate, just need rising external temperature, strengthen temperature gradient.But just easily produce scorched outside and underdone inside phenomenon thereupon.No matter shape how when heating using microwave, microwave can uniformly penetrating, produces heat, and therefore uniformity is improved greatly.
In the utility model, when heating using microwave, heated material is placed on in metal mould, metal die is a cavity for sealing to electromagnetic wave, and electromagnetic wave can not leak, and can only absorb by heating object, air in mould and cell therefor can not be heated, so the thermal efficiency is high.After introducing microwave field, by mix the significant material of some microwave heat-dissipatings in raw material, i.e. microwave heat generating agent can increase internal heat resource in material, thereby this link of heating plasticizing in rotational molding moulding is strengthened.There is the significant material of the Microwave Generating Heat Effects such as carbon black by means of blending, in rotational molding shaping raw material, add that microwave heat generating agent can reach evenly, the effect of high-efficiency heating.In addition, because rotational molding moulding is applied in the large-scale hollow plastic product processing aspects such as storage tank mostly, the mould inner wall of metal has reflex to microwave, by importing microwave at mould outer setting insulating box at dies cavity, as far-infrared heater, make material rapid and uniform heating plasticizing in microwave field, thereby realize the moulding of heating using microwave rotating mould plastics.
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is made to brief description.
