France Aluminum introduces how to choose a degassing unit

1. Look at its color.

The color is pure, without impurities, indicating that the material is uniform.

2. No sticky hands

It indicates that no adhesive is sprayed on the surface, which will not cause secondary pollution.

3. No dregs

Hold the degassing unit with one hand and tap the filter plate with the other palm.

The continuous dripping of ceramsite residues indicates that the filter plate is of poor quality and will cause secondary pollution to the aluminum liquid.

4. No cracking and slagging

Use open flame or electric heating to heat red.

Cool immediately at room temperature without cracking and slagging, indicating that it is a good filter plate.

Adtech told France Aluminum through sales@alalloycasting.com that when purchasing filters, you should carefully evaluate the foam's effective specific surface area or porosity calculation.

You can observe the homogenization state of the mesh surface of the filter plate, and then follow the degassing unit of the cross-section mesh.

If possible, the porosity can be calculated by the drainage method.

The three-dimensional grid is uniform and relatively large porosity is excellent for foam ceramic filter plates.
