In Dalian sand blasting and shot blasting, a teacher in the wire cutting industry Fu said: "the processing and cutting speed of medium wire walking is not slower than that of fast wire walking, but higher than that of fast wire walking. It only reduces the cutting speed in the process of multiple cutting to achieve the cutting effect. In other words, the calculation of medium wire walking is not high efficiency, but - average efficiency. In addition, the processing quality of medium wire walking also tends to slow wire walking."

It uses compressed air as power to form a high-speed jet beam, and sprays spraying materials (copper ore, glass sand, iron sand, brown corundum / emery, etc.) to the surface of the workpiece to be treated at high speed, so as to change the appearance of the outer surface of the workpiece. Due to the impact and cutting effect of abrasive on the workpiece surface, the workpiece surface can obtain certain cleanliness and different roughness, and the mechanical properties of the workpiece surface can be improved, Therefore, it improves the fatigue of the workpiece, increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating. Sandblasting stainless steel is also a popular product in the color stainless steel plate industry. After electroplating process, it has become the second largest process in the industry.

Dalian sandblasting and shot blasting processing after using the sandblasting process on the smooth surface of stainless steel, it can improve the fineness of the surface. Secondly, it increases the uniformity of the whole decorative panel. While improving performance, it will not forget to take value to new heights. To use an analogy, stainless steel is short and poor. Sandblasted stainless steel is a real rich, British dry ice jet. It can be used for various materials, such as steel, as well as softer materials, such as aluminum.

The results of shot peening process vary from material to material, so dry ice spraying is a custom designed process. In general, it can be said that the increase of residual stress, hardness and surface roughness is achievable, but there is a correlation between these effects. Increasing surface roughness usually means that the surface hardness value decreases at the same time. One disadvantage of the dry ice spraying process is the requirements for the working environment: in this process, a sound pressure level of up to 125dB (a) may occur and the concentration of CO 2 in the surrounding air may be increased. In addition, the investment cost of process automation is usually high. In order to give full play to the protective and decorative role of the coating on the substrate, the surface quality of the substrate directly affects the quality of the coating project.

The practice of sand blasting and shot blasting in Dalian has proved that most of the deep defects come from poor surface treatment. Any coating can not give full play to its better performance on the poorly treated surface. Painting on the oxide skin, rust and greasy surface is a great waste of time and money. High-grade surface treatment quality will prolong the service life of the coating.
