Abstract
The invention provides a self-emulsification type dye flaw detection penetration liquid and a preparation method thereof. The self-emulsification type dye flaw detection penetration liquid is characterized by comprising the following components in parts by weight: 20-35 parts of polyoxyethylene fatty acid ester, 30-40 parts of dimethylbenzene, 10-20 parts of nitrobenzene, 10-15 parts of a foaming agent TSHG9 and 5-9 parts of selenium nitrogen red. The preparation method of the self-emulsification type dye flaw detection penetration liquid comprises the following steps: weighing polyoxyethylene fatty acid ester, dimethylbenzene and nitrobenzene according to a ratio, fully stirring for 3-10 minutes, then adding selenium nitrogen red, stirring for 3-10 minutes, then adding the foaming agent TSHG9, and stirring for 2-3 minutes. By virtue of the self-emulsification type dye flaw detection penetration liquid prepared by the method, excessive penetration agent on the surface can be easily removed by only using water after the penetration is completed; the flaw detection cost is low; the penetration liquid can be recycled, processed and reused.
Description
technical field:
The present invention relates to a kind of self-emulsifying type dye check penetrating fluid and preparation method thereof, belong to metal defect detection technical field.
background technology:
Dye penetrant inspection is a kind of surface inspecting method, be mainly used to detect the surface damage of the crackle of such as naked eyes None-identified and so on, as detected the defects (detecting also referred to as PT) such as stainless steel material near surface flaw (crackle), pore, loose, layering, lack of penetration and incomplete fusion.Be applicable to the defect (crackle, pore etc.) checking compactness metal material (weld seam), nonmetallic materials (glass, pottery, fluoroplastic) and product surface Kekelé structure count.The ultimate principle of dye penetrant inspection: the surface being coated in material with colorant, colorant infiltrates damaged part.After placing a period of time, the colorant on surface is rinsed out.Coat developer on the surface cleaned up, damage location infiltrates wherein due to colorant thus sees clearly.Mainly utilize capillarity to make penetrating fluid infiltrate defect, through clean-out system cleaning, surface penetration liquid is removed, and the penetrating fluid in defect remains, the capillarity of recycling developer is adsorbed penetrating fluid residual in defect and reaches the object of inspection defect.
The basic step of dye penetrant inspection is prerinse, infiltration, remove the bleeding agent of excess surface, dry, video picture and inspection, general dye check penetrant all will by means of emulsifying agent or removal of solvents in this committed step of removal excess surface bleeding agent, and the penetrating fluid secondary utilization factor after removal is low, and consume emulsifying agent or solvent, flaw detection cost is high.
summary of the invention:
The object of the invention is to provide a kind of self-emulsifying type dye check penetrating fluid and preparation method thereof for above-mentioned Problems existing, the self-emulsifying type dye check penetrating fluid that the present invention produces, only just easily can remove the bleeding agent of excess surface with water after having permeated, flaw detection cost is low, and penetrating fluid recycles after can reclaiming processing.
Above-mentioned object is achieved through the following technical solutions:
Self-emulsifying type dye check penetrating fluid, comprises polyoxyethylene fatty acid ester 20-35 part by weight, dimethylbenzene 30-40 part, nitrobenzene 10-20 part, blowing agent TSHG9:10-15 part; The red 5-9 part of selenium nitrogen.
Self-emulsifying type dye check penetrating fluid, comprises polyoxyethylene fatty acid ester 25-32 part by weight, dimethylbenzene 32-37 part, nitrobenzene 13-17 part, blowing agent TSHG9:12-14 part; The red 6-8 part of selenium nitrogen.
Self-emulsifying type dye check penetrating fluid, comprises polyoxyethylene fatty acid ester 28 parts by weight, dimethylbenzene 35 parts, 15 parts, nitrobenzene, blowing agent TSHG9:13 part; Red 7 parts of selenium nitrogen.
The preparation method of above-mentioned self-emulsifying type dye check penetrating fluid, gets polyoxyethylene fatty acid ester in proportion, and dimethylbenzene, nitrobenzene add the red stirring of selenium nitrogen and adds blowing agent TSHG9 stirring 2-3 minute after 3-10 minute after fully stirring 3-10 minute.
Beneficial effect:
The self-emulsifying type dye check penetrating fluid that the present invention produces, adopt polyoxyethylene fatty acid ester as after emulsifying agent, make dimethylbenzene, nitrobenzene can become atomic little particle and be evenly distributed in water, define the homogeneous state of " oil-in-water ", non-water-soluble bleeding agent generation emulsification and have water-soluble.Only just easily can remove the bleeding agent of excess surface after having permeated with water, flaw detection cost is low, and penetrating fluid recycles after can reclaiming processing.
