Problems solved by technology

[0004] 1. The sensitivity is limited to a certain extent. The dye molecules in the penetrant are generally very large and cannot enter the cracks smaller than it. If the dye molecules cannot enter, it will not be able to show its existence;
[0005] 2. Pollution is difficult to clean. The dyes currently used in the penetrant, whether fluorescent dyes or red dyes, have strong "dyeing power" for non-metallic materials
However, "colored" penetrants are a source of contamination for non-destructive testing

Embodiment Construction

[0022] In order to further describe the characteristics of this product, the following specific examples illustrate:

[0023] The formula and method are completed through a large number of experiments; in the solution, the specific gravity is appropriately increased, the weight is increased, the volume of the solvent is reduced, and pressure is generated to force the permeate to accelerate the permeation speed under the action of gravity acceleration. The principle is that the distance between molecules decreases, and the force between molecules changes, resulting in faster penetration. It is formed as: specific gravity, high pressure, fast speed and short time.

[0024] First prepare some colorless and transparent penetrating agents, proportioning according to specific gravity, such as preparing 1 kg of colorless and transparent penetrating agents, get 500 grams of polyols (polyols account for 50% of the total proportion); mix 120 grams of surfactants (surfactant accounts fo...

Abstract

The invention relates to engineering flaw detection which is related with micro-fractures on the surface of a metal workpiece, in particular to reaction-type coloring flaw detection penetrating fluid. The invention also relates to an engineering flaw detection method, in particular to a nondestructive flaw detection method which is simple and is simple and convenient to operate. The invention aims to provide a colorless transparent penetrating agent which is really colorless, transparent, pollution-free and natural and does not need to react for the second time. In order to achieve the goal of the invention, the invention is realized in such a mode as follow: the colorless transparent penetrating agent is characterized by consisting of polyalcohol, surface active agent and water, wherein the polyalcohol accounts for 30-60 percent, the surface active agent accounts for 8-15 percent, and the balance is a dissolving agent. By adopting the scheme, the complicated formula in the past is not needed. A detection effect can be achieved only by mixing three ingredients which are the most natural and simplest.

Description

technical field [0001] The invention relates to engineering flaw detection, which is related to fine cracks on the surface of metal workpieces, in particular to a reactive penetrating liquid for coloring flaw detection. [0002] The invention also relates to an engineering flaw detection method, in particular to a nondestructive flaw detection method with simple method and convenient operation. Background technique [0003] After a long period of development, there have been many types of penetrant flaw detection agents used in liquid penetrant testing, but dyes are added to the penetrant to dissolve it, and as the liquid penetrates into the fine particles on the surface of the tested machine Remove the excess penetrant from the outer surface. Spray a developing solution on the surface, and when the dissolving agent volatilizes, a white film will be left, which can suck out and diffuse the penetrating liquid in the crack, making it an extremely fine crack trace that can be ...
