Dispersion detection method and device for recovering silicon carbide

Abstract

The invention discloses a method for detecting the dispersibility of recycled silicon carbide. The method comprises the following steps of mixing the recycled silicon carbide in liquid in a preset weight ratio to obtain mortar; selecting a filter plate with preset mesh number; filtering the mortar in preset weight by using the filter plate, and recording filter time; providing mortar of which the dispersibility meets a production requirement, setting the mortar of which the dispersibility meets the production requirement in preset weight, filtering by using the filter plate, and recording filter time as standard filter time; comparing the filter time with the standard filter time, and detecting whether the dispersibility of the recycled silicon carbide meets the production requirement. The invention also provides a device for detecting the dispersibility of the recycled silicon carbide, which is used in the detection method. According to the method and the device for detecting the dispersibility of the recycled silicon carbide, the degree of dispersion of the recycled silicon carbide is effectively distinguished, the recycled silicon carbide with low dispersibility is prevented from entering cutting production, the risk that the mortar is conglomerated in the cutting process is reduced, and the cutting quality is improved.

Description

technical field [0001] The invention relates to the technical field of recovering silicon carbide, in particular to a dispersive detection method and a device for recovering silicon carbide. Background technique [0002] In the production process of solar silicon wafers, since the silicon carbide mortar cuts the silicon block, the mortar contains silicon powder. When silicon carbide recycles mortar, due to the use of acid and alkali treatment, the recovered silicon carbide contains silicate. If it is not handled properly during the recycling process, it will increase the silicate content in silicon carbide. When the silicate content in silicon carbide increases to a certain stage, it can cause the agglomeration of recycled silicon carbide mortar, thereby affecting the dispersion of silicon carbide in the cutting fluid and the cutting effect. At present, the commonly used method to detect the dispersion of recycled silicon carbide is to use a microscope to observe the amoun...
