Cleaning solvent cleaning type penetrant
A type test block) t test to compare the clean sheet of 46-A load on the test block to infiltrate spray penetration. Penetration in the same time (such as 10 ', bell), two semicircles were used to support cleansing cleansing agent and want to choose benefits (such as lower prices for ethanol or Si-C Phase I Division odd song. For cleansing, further imaging. If the two the same sensitivity, nor a bad background, indicating that cleansing is better, the actual work could have been elected sigh benefit of the arsenic clean cleaning. 4,[link widoczny dla zalogowanych], dry cleaning cleansing solution cleansing type penetrant cases, the general First off with a clean cloth or cotton through the camp with the majority of excess surface penetrant on the cheap to go. and then dipped in sterile cleansing agents clean cotton cloth or on the net on the excess surface penetrant. also can be used cfr lower grid for better toilet paper or a clean cotton cloth. is not permitted to leave the surface fibers or scraps of paper. When comparing the surface mouse pointing right, cleansing is more difficult time to be children again scrub clean. To r Jian disk cleaning effect., O graze with a clean white cloth had been cleared on a sink surface, such as the white background color is no penetration of the system,[link widoczny dla zalogowanych], F Sin Ming shed a net r. or should continue to be cleaned. 5, cleaning should be noted that the purpose of cleaning the main problems is to use cleaning agents remove the excess of net infiltration of surface brush. so cleansing must be insufficient to prevent the washing or clean the hair. cleansing enough to _ [excess penetrant on the surface did not clean up, imaging, due to capillary action, the excess penetrant imaging agent will be adsorbed, resulting in color confusion, unable to identify defects. wash over, that is,[link widoczny dla zalogowanych], the penetration into the defect (the switch to 41) -. a 5crMO, 42CrMo, 42crV, we a ,',: fB216, 4Crl4Mo, 30CrMO, 14008 ',. Z.G1Cr18Ni9Ti, 7' steel. All samples were processed by grinding or grinding. test conditions. ambient temperature of 23 ~ 28 ℃ 15 minutes brushing penetration time, water rinse trials assessing the key indicators. penetrant corrosion,[link widoczny dla zalogowanych], and difficult to dry. every test at least twice over. Table 2 in order to penetrate the surface condition after washing. Table 242CrMO1 · (impeller) I30CrMOl2'7 'steel I3' (impact test block) f the amount of '42CrV: 1 '(impact test block) 2'I8'l4 · 1.4008l1' l (impact test block) {2'08 'a 'I generally weak surface rust i II and light yellow are very good earthworm surface of yellow rust jl very light weak; general l l with a no good I maintain the original luster is very weak. General J Il surface light yellow is good no l Il l surface to maintain the original luster without good I no I better f f with E above the surface of vertical Cr14MO1 · no good to keep the original ●., shiny ZG1Cr2 · no good Ibid 18Ni9Ti (impact test block) 8.. no good Ibid 47 no good Ibid. from the trial we can see that t14 'penetrant materials used for all twelve will cause the surface from corrosion. and that the species i |}. through the cleaning agent is also very easy. 2, comparison 1 , 2 'penetration cut with Sudan IV of the penetrant (1') can produce a heavier piece of yellow rust. 3,1 ', 2,3. penetrant for 4Cr14MO, ZG1Cr18Ni9Ti the workpiece will not rust; by: r1.4008, 42CrV, 80CrMO, 7 'steel impact specimens (good roughness), the surface of the yellow rust free cotton wipe, and for 35CrMO, 42CrMo leaves, rust will not go away. This shows that roughness also affects the level of yellow rust in the strict smoke level. Fourth, the sensitivity verification selection Lu Dong Shipyard HD-ST a 2A type and HD-ST-B-type specimen, other conditions are the same in the case of the four The sensitivity of the penetrant species. 『test. test block shows the crack width, we measured the two points with a microscope, respectively 0.5.ttm and 0.25ixm. The results show that. penetrant sensitivity of four identical,[link widoczny dla zalogowanych], can crack detection 0.5ix111 and 0.25m.. So far, the new penetrant has been used in the production practice more than a year to good effect. (Continued from page 46) one has cleansed, especially for shallow l, wide or some small cracks and other defects in the penetrant is easily washed, imaging, the defect does not show up, resulting in undetected. cleaning inadequate cleaning frequency can be increased up to clean water. wash over, we must re-infiltration and cleaning. 41 are held by light and the original light yellow rust protection on the top surface of the table as the same as the same table as Ze previous one hundred and eleven children. ..
