Stainless steel screen surface processing quality control

by:KNK     2020-10-16
Stainless steel screen surface treatment can be summed up in the process of pretreatment, surface plating, post-processing of three parts. Stainless steel screen surface treatment process control is to first clear the initial state ( Processing stress, oil, dirt type, processing of protective film, adhesive, surface coatings) And the final state ( Product acceptance criteria) 。 Then according to the technological process to determine the process step, the labor, the operating conditions of each process step for item by item, elaboration, as a factor in the need to control, monitoring method to determine each factor. Will not need to control the factors of take out, the current monitoring factors also have no way to get rid of, but as a subject for subsequent research. Usually determine the control factors of monitoring method should pay attention to: 1. As far as possible choose volumetric method, spectrophotometry, polarography, voltammetric stripping, potentiometric determination or titration analysis such as high speed, low cost method; 2. Have proved successful charge measurement method should be adopted; 3. Surface treatment process engineers need to work closely with other professional to success; 4. Try to use on-line detection device; 5. Detecting accuracy with considering technology indicators, such as detection error is 8%, but the scope of inspection specification and test error within the scope of the provisions of technical index.
