Embodiment Construction

[0016] Below in conjunction with example the present invention will be further described.

[0017] The main technical parameters and related requirements of this method:

[0018] 1) Explanation of technical parameters

[0019] ⑴ wetting

[0020] The interface between the material phase and the phase is called the interface. Matter has three phases of gas, liquid and solid, and can form four interfaces: gas-liquid, liquid-liquid, gas-solid and liquid-solid. Generally, the interface composed of gas phase is called the surface.

[0021] Wetting is the process by which one fluid on a surface is displaced by another.

[0022] ⑵ Complete wetting

[0023] When the tangent angle between the liquid-solid interface and the liquid surface at the interface is 0°, the droplet is close to the film form on the solid surface, which is called complete wetting.

[0024] ⑶ non-wetting:

[0025] When the droplet caps larger than a hemisphere, or becomes spherical, on a solid surface, the co...

Abstract

The invention provides a method for application of a household liquid detergent in magnetic particle inspection of components. The method makes a breakthrough in a conventional preparation method for paste-water magnetic suspension; through addition of the household liquid detergent, wetting performance of paste-water magnetic suspension on a workpiece to be inspected is substantially improved, so the technical effects of saved detection time, improved detection efficiency, reduced production cost and minimized environmental pollution are obtained.

Description

technical field [0001] The invention relates to a magnetic particle flaw detection technology for parts and components of metallurgical equipment. The detection magnetic suspension is prepared by adding household detergent to the conventional magnetic paste water magnetic suspension, and the method is verified to have reached the specified detection quality through a water break test and a sensitivity test. scope. Background technique [0002] The stress-bearing parts (parts) of metallurgical equipment need to be regularly inspected by magnetic particle inspection to find out various harmful defects, such as opening cracks and fatigue cracks on the surface and near the surface. At present, most of the on-site inspections use the magnetic suspension prepared by magnetic paste and water. In order to ensure the normal operation of the inspection and the requirements of the detection sensitivity, it is necessary to completely remove the oil and dirt on the surface of the workpie...
