Brush plating technology in the curling round of repair work


Surface. After finishing, the surface roughness should Ra3.2 above. If oil can be alcohol or acetone for cleaning. (B) the net power for 1, electrode connection phase: plated pen then positive, then the negative piece. 2, the operating voltage: 1O ~ 20V. 3, plated pen and the relative speed of the workpiece 9 ~ 18m/min. 4, power net time of 10 to 30 seconds. 5, rinse with water, nothing to do spot or hanging drops. 46 (c) activation by 2 # and 3 # two kinds of activation solution was activated, and the first activation solution with 2 #, # live with 3 million in liquid. 1, then stick electric phase: plating pen then negative, then positive workpiece. 2, the operation power turn: 2 # activation solution for the 6 ~ 12V; 3 # activation solution for the 15 ~ 25V. 3, plated pen and the relative speed of the workpiece is 9 ~ 18m/min. 4, activated when the Q: The 10 to 30 seconds. 2 # activation solution rinse to use after activation, but activation solution # 3 after activation of 5,3 # do not have to rinse the surface after activation solution activation requirements: silver gray without spots, nothing to do spot or hanging drops phenomenon. (E1) special nickel-plated for a bottom layer 1, the electric net: not activated by water. 2 can be immediately special nickel plating, the electrode connection phase: Yun-plated pen then. Workpiece then negative. 3, first in the case of no electricity. Key document picks up special nickel plating bath, wipe the area to be plated】 o 3 seconds after power in the lo ~ 2ov Brush 3 ~ lO seconds. 4, the normal voltage Plating: Plating Voltage】 O ~ 2OV, time 30 to 120 seconds. 5, the workpiece and the plating pen relative speed of transport the soul of 6 ~ 012m/min. 6, the coating thickness 0.001 ~ 0. (IQSmm (without measurement, the surface of the eye as to be uniformly deposited on the plated layer of nickel will be properly light yellow). 7, rinse with water. (E) plating layer and working layer over foot (turn 57 next Zhen) Table 2 trough Paul (ram) 05. I.. s0.700.75O.80.85090.g51.O quality indicator 1I601170; 1140l16011501140l1401160I1401170 the data in Table 2, we do quality indicators and groove depth diagram to determine the quality Indicators and What is the relationship between the groove depth (Figure 2). It can be seen from Figure 2, the quality indicator is the increase with groove depth fluctuations, and remained in the vicinity of a parallel line so you can determine the slippery led extended groove depth, no effect on yarn strength. According to the results of the trial, the choice of drafting in the slippery, we can try to choose dark, but not too deep to use, but also increase the work of the roller system labor intensity. So, we the experiment, select the groove depth 0.9mm. In 0. 9ram slippery protracted deep large area on the machine after drafting, drafting zone is not the phenomenon of pressure not open, the spring yarn is gone,[link widoczny dla zalogowanych], Yarn quality has clearly improved. reflect the most obvious is the weft, weft yarn finished cloth, the fabric quality and significantly increase the labor intensity of workers repair cloth down first-class storage products has greatly improved rate. The above conclusion is to experiment with cotton yarn obtained 55/4555tex. If numbers change, changes in mixing ratio, slippery groove depth should be re-draft selection through the test, we concluded that: numbers increase, slippery stretch of sediment tank should be deepened, on the contrary, should be lighter in front of test results based on that: slippery led war Chung groove depth and yarn quality index does not matter. Therefore, if the numbers of small spinning yarn, but unfortunately slipped drawing groove depth can be well fixed; if flax blended yarn spinning numbers increased, in order to ensure the quality, you must draft slot to increase the slipperiness; increased if the content of flax, slippery stretch the depth of groove should also be increased. In short, We spun linen yarn, in the process of drawing using the slippery, should be based on the amount of linen sets, numbers, etc. to experiment with different depths, thus drawing out the best slippery groove depth. (I-connected 46) Fast Nickel plated coating l,[link widoczny dla zalogowanych], Operating Voltage: 8 ~ 20V2, polarity phase; plated pen then positive, then the negative piece. 3, plated pen and the relative speed of the workpiece 9 ~ 24m/min. 4, according to thickness of the coating, be a good amp-hour meter, ensure that there are 0.10 to 0.20 of the grinding layer 5, clean the surface. (f) cylindrical grinding to achieve the dimensional accuracy of lOOm {repaired. After electric curling brush axle diameter after repair than the original shaft hard, more resistant to wear. greatly improve the curled round of life. successful practice, and we felt,[link widoczny dla zalogowanych], brush plating technology has many advantages,[link widoczny dla zalogowanych], it is particularly suitable for small size, wrought thin, high-performance,[link widoczny dla zalogowanych], Local non-disintegration of the parts on-site repair. It can greatly reduce equipment maintenance costs, extend life, is a very worthy technical maintenance. 57
