Problems solved by technology

[0002] The traditional stainless steel sandblasting process generally only uses one kind of sand. If glass sand is used, the surface effect after sandblasting is better, but the cost is high, the price of glass sand is high, and it is not durable, and the consumption of glass sand is large; if red pomegranate sand is used, The cost of sandblasting is low, and the cost of sand is low, but the effect of sandblasting is poor and cannot meet the process requirements

Embodiment 1

[0008] For different products, the requirements for sandblasting process are also different. For the sand blasting treatment of stainless steel, the specific operation steps are as follows.

[0009] 1. Preparation

[0010] Choose the appropriate mesh glass sand and red pomegranate sand, so that the mass mixing ratio of the two is 4:6, and the compressed air used for sandblasting must be dry and oil-free.

[0011] 2. Before sandblasting, use masking tape, metal sheet, collar, hard wood board, or rubber to shield and protect the non-effective surface. Blasting abrasives must be kept clean and dry. Abrasives contaminated by old coatings, scale, or grease are not allowed.

[0012] 3. Sandblasting

[0013] When spraying, the angle of the nozzle to the surface should be close to 90°, but slightly smaller, so that the abrasive will not just bounce back to the operator, and the distance between the spray gun and the workpiece is 50-150mm.

[0014] The blasting sequence is to cover...

Abstract

The invention provides a mixed sand blasting process. According to the sand blasting process, glass sand and garnet sand in a mixing ratio of 4:6 are used, the requirements of the sand blasting process can be satisfied, the cost can be greatly reduced and the sand can be repeatedly used.

Description

technical field [0001] The invention relates to a mixed sand blasting process, which belongs to the technical field of metal surface treatment. Background technique [0002] The traditional stainless steel sandblasting process generally only uses one kind of sand. If glass sand is used, the surface effect after sandblasting is better, but the cost is high, the price of glass sand is high, and it is not durable, and the consumption of glass sand is large; if red pomegranate sand is used, The cost of sandblasting is low, and the cost of sand is low, but the effect of sandblasting is poor and cannot meet the process requirements. Contents of the invention [0003] The invention provides a mixed sand blasting process, which mixes glass sand and pomegranate sand according to a certain mixing ratio, overcomes the above defects, not only reduces the cost, but also satisfies the technological requirements of the product quality after sand blasting. [0004] In order to solve the ...
