Abstract
The invention discloses a radiographic inspection compensating daub for materials with unequal thicknesses. The daub is composed of metal powder a material of which is as same as the material of a workpiece to be detected, transformer oil, glycerol, stearic acid and a curing agent, wherein the volume ratio of the metal powder to the transformer oil is 3:1; the glycerol accounts for 1-2% of the total volume of the metal powder and the transformer oil; the stearic acid accounts for 0.7-1.2% of the total volume of the metal powder and the transformer oil; and the curing agent accounts for 0.1-0.5% of the total volume of the metal powder and the transformer oil. The invention also discloses a method for preparing the compensating daub. The radiographic inspection compensating daub for the materials with unequal thicknesses has the advantages of low cost and convenience for manufacture and use.
Description
Technical field
The present invention relates to the radiographic examination (complete) technical field, refer to a kind of not equal thickness material radiographic examination (complete) compensation clay and preparation method thereof particularly.
Background technology
Radiographic examination (complete) is one of main test method during industry is made; When the welding structural element of equal thickness does not carry out radiographic examination (complete); Can on film, produce the different image of blackness, can cause bigger influence, therefore need compensate result of determination; Make to produce the uniform image of blackness on the film, so that improve quality inspection.
The method that compensates for radiographic examination (complete) is at present normally used the compensation powder, and this method is for some planes of making in laboratory or have the comparatively practicality of inner chamber workpiece.Workpiece is in irregular position form or workpiece is positioned at site but work as, and the compensation powder just can not play a role.
Another kind method is to adopt the compensation clay that equal thickness radiography is not compensated.Yet, present composition and the also rare research of preparation method for said compensation clay.
Summary of the invention
The object of the invention is exactly that the low and manufacturing of a kind of cost and not equal thickness material radiographic examination (complete) compensation clay easy to use and preparation method thereof will be provided.
For realizing above-mentioned purpose, the not equal thickness material radiographic examination (complete) compensation clay that the present invention designed is made up of metal powder, transformer oil, glycerine, stearic acid and the hardening agent identical with workpiece material to be detected; Wherein, the volume ratio of said metal powder and transformer oil is 3: 1, and said glycerine accounts for 1～2% of said metal powder and the mixed cumulative volume of transformer oil; Said stearic acid accounts for 0.7～1.2% of said metal powder and the mixed cumulative volume of transformer oil; Said hardening agent accounts for 0.1～0.5% of said metal powder and the mixed cumulative volume of transformer oil.
Not equal thickness material radiographic examination (complete) of the present invention compensation clay raw materials cost is low, be prone to obtain, preparation and easy to use; No matter workpiece is what form, what material or what place; The compensation clay can be combined closely with workpiece; Guarantee that thin position is consistent with thicker position image blackness on egative film, to reach the purpose of compensation.
Alternatively, said metal powder is a kind of in iron powder, aluminium powder or the copper powder.
Further, the specification of said metal powder is 80～120 orders.
Further, said transformer oil is the 20# transformer oil, its modest viscosity, and volatility is little, and peculiar smell is lighter.
The present invention also provides the preparation method of aforementioned not equal thickness material radiographic examination (complete) compensation clay, and it may further comprise the steps: said metal powder, transformer oil, glycerine, stearic acid and hardening agent are pressed said volume ratio weighing; Said metal powder, transformer oil, glycerine and stearic acid are joined in the container, stir; After leaving standstill a period of time, add said hardening agent again and mix and process said compensation clay.
Preferably, said time of repose is 10～15 minutes, and is fully warm to guarantee various raw materials.
