What is the chemical polishing method of stainless steel wire spring?
Stainless steel spring is an elastic element, which requires corrosion resistance, medium temperature resistance and non-magnetic use in many industries such as chemical machinery and electronics. Stainless steel springs can produce large elastic deformation when loaded, and convert mechanical work or kinetic energy into elastic potential energy. After unloading, the deformation of the stainless steel spring disappears and returns to its original state, and the deformation energy is converted into mechanical work or kinetic energy. The first step is degreasing and descaling the stainless steel spring. There are two ways to use it: immerse the stainless steel spring in a plastic container filled with metal cleaning agent A diluted with clear water (the dilution ratio of cleaning agent A to clear water is about 1: 1 or 1:2), and take it out and clean it with clear water. In this way, the surface of stainless steel spring has a matt effect. In ultrasound equipment, the ratio of cleaning agent to clean water is about 1: 30, and it is appropriate to restore the natural color of the spring surface without oil stain and scale. Rinse with clean water after taking it out, so that the surface of stainless steel spring can achieve matte effect. Both of the above methods can be applied to high-precision springs. Cleaning agent A is put into a vibration polishing machine equipped with coarse abrasive and spring or hexagonal drum (the optimal volume ratio of spring to coarse abrasive is 1: 3, and the amount of cleaning agent is 1%-2% of the weight of spring). After grinding and polishing, rinse with clean water, and the scratches on the spring surface will be gone, which improves the smoothness of the spring surface. But this method is not suitable for springs with high precision and easy winding. Step 2: Polishing the stainless steel spring: put the brightener B into a vibration polisher or hexagonal drum filled with coarse abrasive (the volume ratio of the spring to fine abrasive is 1: 3, and the dosage of brightener B is about 1%-2% of the weight of the spring, and the longer the time, the brighter it will be), then take it out, wash it with clear water and dry it to make the surface of the stainless steel spring shine like nickel plating.
