What safety measures should be taken in Dalian sandblasting processing

Sandblasting means that the stainless steel plate surface presents a fine bead like sand surface. Stainless steel sandblasting is divided into two types: matte sandblasting and bright sandblasting. Matte is sandblasted when the board is still on 2B surface, while Bright is sandblasted after the surface is polished to a mirror surface. The medium used for sandblasting is sand particles with sharp edges, such as brown corundum, white corundum, iron sand, etc; The medium used for shot peening is circular particles without edges, such as steel shot, iron shot, glass shot, and ceramic shot.

To make the surface of an item flat and smooth, it is necessary to remove and polish the dirt on the surface of the item, which can make the surface smoother. Then, through different exchanges, different abrasives make the surface of the item smoother, smoother, and brighter. However, not only can the surface of the item be smooth and bright, but it can also make the roughness of the item different, improve the adhesion between the workpiece and the coating, plastic, and make the adhesion stronger and higher in quality.

What safety measures should be taken in Dalian sandblasting processing

1. Check the dust removal system properly

Before carrying out sandblasting operations on the sandblasting machine, the operator must inspect the dust removal system. If there is a problem with the dust removal equipment, the operation and use must be stopped. At the end of each shift, clean up the spilled abrasive, which requires manual work.

2. The airtightness of the prosecution system

Regularly check the connection ports of the system to ensure better sealing of the hydraulic pipeline system. If there is any air leakage, it should be maintained in a timely manner. This operation should generally be carried out once a month. Regularly clean the dust in the dust removal box.

The function of sandblasting is to achieve a certain degree of cleanliness and different roughness on the surface of the workpiece, improve the mechanical properties of the workpiece surface, enhance the fatigue resistance of the workpiece, increase the adhesion between it and the coating, extend the durability of the coating film, and also facilitate the leveling and decoration of the coating. The process of sandblasting can remove rust, without the need to polish and remove rust before sandblasting.

Most mechanical engineers have little knowledge about sandblasting, which is very simple. It uses a high-speed jet beam formed by compressed gas to drive the spraying material. Generally, three types of materials are commonly used, namely quartz sand, diamond sand, and iron sand. Of course, there are other materials that can be sprayed onto the surface of the workpiece at high speed. Due to the impact and cutting of abrasives on the surface of the workpiece, the mechanical properties of the workpiece can be improved by treating the surface.
