High Quality White Aluminum Oxide Sand Philippines

For example, the density of plane distribution of pores is related to the type of acid which is the basic component of electrolyte(pink aluminum oxide), i.e. it decreases with the order of sulfuric acid (15%), oxalic acid (8%), chromic acid (3%) and real acid (4%). At the same time, for the same acid, the pore density decreases with the increase of current. In order to obtain thicker alumina film, dural anodization is required(brown aluminum oxide sandblasting). This process is called curing.

This is an effective method to improve the bonding properties of polymer materials(black aluminum oxide). One is called "corona discharge method". The material to be treated is placed between two flat electrodes. In the air (or nitrogen, nitrogen, oxygen, etc.) environment, high voltage (such as 150000v alternating current or direct current) is applied to discharge the gas and bump the surface to be treated(glass bead abrasive). The time is from 1s to tens of minutes.

This is similar to the glow discharge method(brown fused aluminum oxide). According to the surface energy theory, the contact angle decreases and the ultimate surface tension increases after the surface treatment, because the surface improves the penetration ability and adhesion performance of the adhesive(white aluminum oxide grit). The alumina layer formed by common electrode oxidation is thin (30 pm at most), and its wear resistance is not as good as that of thicker alumina film.

Its principle is to continuously provide energy with high frequency (RF) without electrode, so that the gas molecules are partially excited into ionized gas (plasma) with positive ions and electrons, and then push the surface to be treated(white aluminum oxide). In principle, all gases can be used, but common emotional gases such as nitrogen, hydrogen and gauge are easy to be excited(garnet abrasive price). The other is called "activated gas plasma method", which is called "plasma method" for short.

Another view is that only the "bonding strength surface layer before and after weak surface plasma treatment" on the surface is removed during the surface treatment(brown aluminium oxide 24 mesh), while a thin and tough cross-linked film is produced on the surface, which improves the bonding performance due to the high cohesive strength of the film(glass beads manufacturers). The ultimate surface tension of the treated material is improved and the bonding performance is greatly improved.

Therefore, this is the view of "the theory of weak surface layer"(white fused alumina). However, more recent researches have pointed out that the surface tension is still increased even though there is still a "weak surface layer" on the treated surface(fused alumina). The treatment of polymer materials by discharge method has the advantages of high speed, good effect, easy operation and control, and there is no pollution problem of corrosive solution by chemical method.

But there is little calculation strength of liquid substance. For example, fill a little water in the middle of two glass plates(arc fused alumina). Because the water has moistened the glass surface, it is very difficult to pull the two glass plates apart. However, they can be separated only by a small shear force(steel shot abrasive). Therefore, the liquid adhesive must be turned into solid through appropriate methods after moistening the surface of the adherend Able to bear all kinds of loads.
