Microcrack detection equipment and detection method for ceramic matrix and penetrant preparation method

Abstract

The invention discloses microcrack detection equipment and method for a ceramic matrix and a penetrant preparation method, and belongs to the technical field of ceramic materials. The detection equipment comprises a moving assembly, two cleaning tanks and a detection platform, wherein the moving assembly is used for sequentially moving the to-be-detected ceramic matrix to the two cleaning tanks and the detection platform, a penetrating agent used for immersing the ceramic matrix is loaded in the first cleaning tank of the two cleaning tanks, a spraying assembly is arranged on the second cleaning tank and used for washing the penetrating agent on a surface of the ceramic matrix, and the detection platform is used for accommodating the ceramic substrate so that a user can observe the micro-cracks, permeated by the penetrating agent, on the ceramic substrate. The detection equipment is advantaged in that the operation method for detecting the microcracks through the penetrant is simple, detection equipment is small, cost is low, limitation of shapes and sizes is not needed, the detection result is visible to naked eyes, the corresponding detection equipment is built, and large-batch continuous production operation of enterprises can be achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of ceramic materials, and in particular to a microcrack detection device, detection method and penetrant preparation method of a ceramic substrate. Background technique [0002] Microwave dielectric ceramics refer to ceramics that are used as dielectric materials in microwave frequency band circuits and realize one or more functions. Among them, microwave frequency bands can be UHF (Ultra High Frequency, ultra high frequency), SHF (Super High Frequency, ultra high frequency) and many more. Microwave dielectric ceramics have excellent properties such as high dielectric constant, low dielectric loss, and low resonant frequency temperature coefficient. They play dielectric isolation, dielectric waveguide, and dielectric resonance in microwave frequency circuits. They are resonators, filters, duplex It can be widely used in many fields such as personal portable mobile phones, microwave...

AI Technical Summary

Problems solved by technology

At present, dry pressing is often used in the molding of microwave dielectric ceramic blanks, but the ceramic substrate is prone to micro-cracks during the preparation process, and some of these micro-cracks cannot be recognized by human eyes, which will affect product performance.

[0004] In the prior art, x-ray flaw detectors are generally used to detect microcracks in ceramic substrates. Although microcracks can be detected effectively, the cost of x-ray flaw detectors is expensive, and the position of x-ray flaw detectors is relatively fixed, and the mobility is poor. Suitable for mass production enterprises
