　　 What problems should be paid attention to when blasting garnet abrasives? The cleaning effect of sandblasting directly affects the service life of the coating. The selection of abrasives and the placement and maintenance before blasting are very important. What problems should be paid attention to when using garnet blasting abrasives? Let’s take a look together.
What problems should be paid attention to when garnet abrasive sandblasting
　　1. Humidity of the air: When the relative humidity in the air reaches 85% or the surface temperature of the object to be blasted is less than 3 degrees Celsius, the blasting operation should be stopped.

2. The time interval between sandblasting and painting: paint treatment should be carried out immediately after sandblasting with garnet sand, so that the contact time between the sandblasted object and the air is short, and the dust and moisture content falling on the surface of the workpiece can be maintained. Excellent sandblasting effect and longer coating life.

3. Try to use dust-free sandblasting abrasives: the common dust in the sandblasting process is due to material reasons, such as copper slag and quartz sand with light specific gravity, which are prone to produce floating objects; even garnet sand with high specific gravity is because Rough processing, without fine screening or washing, there is dust in the abrasive, and dust will also be generated. Dust-free garnet abrasives can be used, 6 times of washing, 4 times of sieving, specific gravity 4.0-4.2, and very little dust.
