Embodiment 1

[0040] The composition ratio of the non-combustible colored flaw detection cleaning liquid is as follows:

[0041] Ingredient wt%

[0042] Glycine isobutyl ester 80

[0043] Propylene Glycol Carbonate 12

[0044] Gunner TSHG 8

[0045] The preparation steps are as follows:

[0046] ① Screen raw materials, the purity of each raw material is chemically pure;

[0047] ②Weigh the raw materials, and weigh the amount of each raw material according to the above formula ratio;

[0048] ③At room temperature, the raw materials are mixed in the middle reaction vessel, sealed and stirred for 2 hours;

[0049] ④After the stirring is finished, filter through a 200-mesh screen to obtain the finished product of cleaning liquid;

[0050] ⑤ Put the obtained permeate product into a pressure tank using nitrogen as a propellant to make an aerosol tank product.

Embodiment 2

[0052] The composition formula of the non-combustible colored flaw detection cleaning liquid is as follows:

[0053] Ingredients: wt%

[0054] Glycine isobutyl ester (base solvent) 30

[0055] Propylene carbonate (hydrate adjuvant) 40

[0056] Cannoning agent TSHG (degassing agent) 30

Embodiment 3

[0058] The composition formula of the non-combustible colored flaw detection cleaning liquid is as follows:

[0059] Ingredients: wt%

[0060]Glycine isobutyl ester 65

[0061] Propylene Glycol Carbonate 22

[0062] Gunner TSHG 13

[0063] The preparation steps and usage methods of Example 2 and Example 3 are the same as those of Example 1, except that the proportions of the ingredients are different during the configuration, and chemically pure raw materials are also selected for each of the raw materials.

[0064] The non-combustible penetrant flaw detection cleaning liquid prepared according to the component ratios of Example 1, Example 2 and Example 3 is used together with the non-combustible penetrant flaw detection developing liquid and the non-combustible colored penetrating liquid.

Abstract

A noncombustible painted inspection cleaning liquid, the characteristic is its component and weight percentage: the isobutyl Glycine 30-80 wt%; the carbonate propylene alcohol 12-40 wt%; the blowing agent TSHG 8-30 wt%. The invention is that the noncombustible painted inspection cleaning liquid, the noncombustible painted inspection developer (other invention case applies) and the noncombustible painted inspection penetrant (other invention case applies) use complementally. The invention can not only achieve inspection assignment, but also prevent burning accident effectively.

Description

Technical field [0001] The invention relates to engineering flaw detection, belonging to a fine chemical formula and a preparation process, in particular to a non-combustible colored flaw detection cleaning liquid and a preparation method thereof. Background technique [0002] There are many types of penetrant detection agents used in liquid penetrant inspection in the world. However, they all have some common weakness: flammability. [0003] As we all know, combustion has three basic elements: combustible substances, oxygen and high temperature. If one of the elements is blocked, burning can be avoided. Most of the existing colored penetrant flaw detection agents are flammable organic raw materials, and no barrier measures have been taken. [0004] In order to solve the problems in the on-site construction of shipbuilding projects, it is necessary to detect defects such as welding cracks. During detection, there are unavoidable open flames such as welding and gas cutting. At thi...
