Embodiment Construction

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be pointed out that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] The insulating coating of the embodiment of the present invention, the components of the insulating coating include at least 10 parts by weight of microsilica powder and 1 part by weight of quartz fiber, and when the quartz fiber is 1 part by weight, the microsilica powder can be 300, 250 , 200, 100, 80, 50 or 10 parts by weight of different values. When preparing an insulating coating from the insulating coating of the present invention, it needs to be fully mixed with water, and the percentage of water to the total mass (that is, the sum of the mass of microsilica fume and qu...

Abstract

The invention discloses an insulating coatings consisting of at least 10 parts of microsilica and one part of quartz fibre by weight. The invention also discloses a device for purifying polysilicon and a method thereof for ionization resistance and short circuit resistance. In the polysilicon purifying device, the high-temperature part easy to ionization or short circuit is coated with an insulating coating prepared by the insulating coatings in the invention. The insulating coatings in the invention overcomes the defect of easy falling off of the coating only using microsilica in the prior art and gives full play of insulativity of quartz. The invention effectively avoids gas ionization and short circuit of the high-temperature parts in the device under the vacuum condition.

Description

technical field [0001] The present invention relates to anti-ionization and anti-short-circuit technology of polysilicon purification equipment and electrical equipment, especially an insulating coating for anti-ionization or anti-short circuit, polysilicon purification equipment with the insulating coating and its anti-ionization and anti-short-circuit method, and The invention relates to an electrical equipment with the insulating coating. Background technique [0002] Induction heating furnaces are more and more widely used in the preparation or purification of various materials, such as metal refining in metallurgy, crystal growth and purification of semiconductor materials, etc. However, vacuum conditions are usually required in the refining process, but the gas is easily ionized in the electric field under vacuum conditions. [0003] In order to overcome the above problems, it is necessary to use a material with very good insulating properties as a medium or smear it ...
