非标准螺丝产业产品制作测试

非标准螺丝行业生产产品将接受测试,如异常螺丝、非标准螺丝等。测试后将发现不合格产品,然后提高自身产品质量。只有这样,我们才能为客户提供更好的产品并赢得用户青睐

非标准螺丝测试、外观和质量要求绑定器; 非标准螺丝检查、电容检查.螺丝涂层厚度可用微米、动性卡列器、插头标量器等测试.磁法测量涂层厚度磁度计是磁性厚度计表表层非损度测量磁性矩阵;微分法称合算法放大光学显微镜上嵌定带微件测量段涂层厚度 时序流法

Timing flow method is to use the solution to dissolve the coating on the local surface of the coating, according to the local coating to dissolve the time required to calculate the thickness of the coating.There are coating drip method, anode dissolution coulomb method and so on.Screw coating adhesion strength test: evaluation of coating and substrate metal adhesion methods are many, usually have the following: friction polishing test;File test;Scratch method;Bending test;Thermal shock test;Extrusion method.Stainless steel screw coating corrosion test: coating corrosion test methods are: atmospheric explosion test;Neutral salt spray test (NSS test);Acetate Spray Test (ASS Test), Copper Accelerated Acetate Spray Test (CASS Test);And corrosion paste corrosion test (CORR test) and solution drop corrosion test;Impregnation test, interdip corrosion test and so on.
