Brown corundum is made of bauxite, coke (anthracite) as the main raw material, smelted at high temperature in electric arc furnace, brown corundum has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance. In the application process has the characteristics of non-exploding, non-powdering, non-cracking. So what do you pay attention to when blasting brown corundum abrasives?
Brown corundum abrasive sandblasting attention to what:
1, according to the requirements of the brown corundum on the part of the sand blasting is not allowed to do a good job of protection.
2, into the blasting chamber, in the blasting process, will not collide with each other, obstruction.
3, close the door of the blasting machine. Brown corundum start shot blasting work, the door of the blasting machine must be closed to avoid sand and dust pollution shot blasting environment.
4, shot blasting steel bead size of 1 ~ 1.5mm.
6, sandblasting brown corundum construction should also check the shot blasting workpiece, if there is not sprayed or shot bad parts, the workpiece re-spray.
5, sandblasting, gun nozzle and workpiece spacing to maintain at about 10 ~ 20cm, vertical uniform movement, while rotating the workpiece in hand, so that the abrasive surface evenly sprayed shot.
Brown corundum in the process of using many details are related to the later use of the effect, and in the application of the time we should also do some protection. Such abrasives in the process of use, especially to the sandblasting link, must pay attention to these matters.
