How to store the white fused alumina fine powder

White fused alumina fine powder is excellent for casting powder and refractory castable. WFA powder 200 mesh, 220 mesh, and 325 mesh are always for those applications. The consumption quantity is large so many users buy a large batch of goods. So it has to pay attention to the storage of the powder:

1. Always keep ventilated and dry

Avoid humidity in the warehouse. Moisture will make the WFA powder agglomerate to blocks after absorbing humidity from the air.

Water vapor will hydrate, hydrolyze, and carbonic acid white fused fine powder. Humidity environment causes water spots, whitening, weathering, erosion, rust yellow, and other pathological changes.

2. Package isolated from air

White fused alumina powder suppliers always make a plastic bag as an inner bag and seal it. If using part of the bag, users should seal it again. That will make the WFA isolated from the air.

3. Dustless circumstance

Dust will pollute the pure WFA powder. The storage should avoid dust workshops and warehouses.

4. Do not cover carpet and sundries for a long time

In order to keep the white corundum ventilate, it is necessary to avoid covering the white fused alumina bag with carpets and sundries for a long time, otherwise, the moisture cannot volatilize through the pores. White corundum will be affected by moisture due to excessive moisture content
