    White Fused Alumina- WFA suppliers We produce a specialized grade of white corundum that used in sandblasting abrasives. It is a harder and higher friability than other blasting materials, it can do fast cutting action and shatter on impact and break down quickly, without doing as much destroy or impact to the substrate, specially minimized destroy to thin materials. Great for the aircraft and automotive industries and preparing a hard surface for painting, blasting and cleaning of engine heads, valves, pistons and turbine blades. In addition, also used in cleaning medical tools.

    The principle of white fused aluminum oxide sandblasting is mainly that the automatic sandblasting machine uses compressed air to flow at high speed in the nozzle to form a negative pressure to generate ejection effect, and the white corundum sand is sucked into the nozzle through the sand pipe, and then injected into the workpiece at high speed by the nozzle with the compressed air flow surface, to achieve the purpose of sandblasting. In the working state, the compressed air and sandblasting white corundum are sprayed while mixing, so that the compressed air can be fully utilized, the air flow and the white fused alumina flow can be adjusted easily, an ideal mixing ratio can be obtained, and the energy and white corundum abrasive consumption is less, with very high cleaning efficiency.

    After knowing the principle of alumina white sandblasting, let’s take a look at how it works:
    First, dust removal:
    Dust removal is an important link that must be done before sandblasting. The air around the object to be sandblasted is sucked into the sandblasting cabin through the dust collector, so that the sucked dust enters the dust removal unit and is filtered by the dust filter bag. Fall into the ash hopper.

    Second, sandblasting:
    After the object to be sanded is dedusted, the filtered clean air is circulated into the white corundum sandblasting gun to accelerate and eject the white corundum abrasive to complete the sandblasting work.

    Generally speaking, sandblasting white corundum sandblasting basically consists of these two steps, but one thing to pay attention to when performing operations is that because white corundum has extremely high hardness, the sandblasting gun equipment with lower hardness will wear out faster , When encountering white corundum sandblasting work, try to use boron and silicon-carbon alloy spray guns with higher hardness. Although white corundum sandblasting seems relatively simple, each step is more important. Whether it is dust removal, worker experience or spray gun selection, if there is a problem in one link, it will be difficult to achieve the desired effect.
