Problems solved by technology

[0003] At present, the polishing of stainless steel metal products is mostly the traditional mechanical polishing process. This polishing process is usually high-temperature pickling after degreasing. The pickling solution often contains chromic acid, hydrofluoric acid, nitric acid and other toxic substances. , not only high operating cost, but also easy to pollute the environment and corrode equipment
In recent years, although some companies use polishing wax to mechanically polish stainless steel metal products, which reduces operating costs and environmental pollution, there are many problems due to the low quality of polishing wax and unreasonable use methods, such as: polishing The post-gloss is not high, the polishing is not thorough and comprehensive, a small amount of harmful substances remain on the surface, and there are fine scratches on the surface after polishing, etc.

Embodiment 1

[0017] The specific processing method is as follows:

[0018] a) Surface degreasing treatment, the composition and content of the degreasing liquid selected for surface degreasing treatment are: sodium hydroxide 30 g / L, sodium carbonate 20 g / L, sodium phosphate 10 g / L, emulsifier 2 g / L; The temperature of the oil is 50°C, and the oil removal time is 5 minutes.

[0019] b) Mechanical rough polishing treatment, first select a motor polishing machine with a power of 4 kW and a rotational speed of 2880 r / min, and then start the motor polishing machine to coat 3B purple coarse polishing wax on the surface of the hemp wheel , and then contact with stainless steel for rough polishing. The rough polishing time is 5 minutes, so as to remove surface trachoma, burrs and thick oxide layer, and make the rough surface initially smooth.

[0020] c) Preparation of ultra-fine polishing wax. The preparation of super-fine polishing wax includes the following steps: 1) First mix 22.5% oil, 5% lu...

[0023] The specific processing method is as follows:

[0024] a) Surface degreasing treatment, the composition and content of the degreasing liquid selected for surface degreasing treatment are: sodium hydroxide 60 g / L, sodium carbonate 40 g / L, sodium phosphate 20 g / L, emulsifier 3 g / L; The temperature of the oil is 60°C, and the oil removal time is 10 minutes.

[0025] b) Mechanical rough polishing treatment, first select a motor polishing machine with a power of 4kW and a rotational speed of 2880 r / min, and then start the motor polishing machine to coat 3B purple coarse wax on the surface of the hemp wheel. Then contact with stainless steel for rough polishing. The rough polishing time is 5 minutes, so as to remove surface trachoma, burrs and thick oxide layer, and make the rough surface initially smooth.

[0026] c) Preparation of ultra-fine polishing wax, the preparation of ultra-fine polishing wax includes the following steps: 1) first mix 23.5% oil, 6% lubricant and 4% ...

Abstract

The invention provides an ultra-finishing polish processing method of a stainless steel metal product. The stainless steel metal product is subjected to finishing polish by ultra-finishing polish wax. The ultra-finishing polish processing method comprises the following steps of a) conducting surface oil removing treatment, b) conducting mechanical rough polish treatment, c) preparing the ultra-finishing polish wax, and d) conducting ultra-finishing polish treatment. The invention discloses the ultra-finishing polish processing method of the stainless steel metal product, which is simple and convenient to implement, and low in environmental pollution; the surface of the stainless steel metal product subjected to the ultra-finishing polish processing has very high glossiness, and is free from residual hazardous substances and tiny scratches; and the stainless steel metal product has stronger market competitiveness than the similar metal products.

Description

technical field [0001] The invention relates to a metal product, in particular to an ultra-fine polishing processing method for a stainless steel metal product, and belongs to the technical field of metal products. Background technique [0002] With the improvement of people's living standards, stainless steel metal products are increasingly entering kitchen utensils, tableware, etc. in family life. This requires higher and higher requirements for stainless steel metal products. There is no harmful residue, and the appearance is mirror-bright, delicate and pleasing to the eye. Most stainless steel metal products are processed by high temperature such as hot rolling, forging, heat treatment, welding, etc. During the processing, thick oxide skin will appear on the surface. In addition, due to the different geometric shapes of stainless steel metal products, the gray film produced during welding , black slag, etc. remain on the surface of metal products. For this reason, the s...
