Application And Precautions Of Boron Nitride Coatings

Product Features of Boron Nitride Coatings It can be used in aluminum, magnesium, zinc and other alloy casting, gravity/low pressure casting, forging, powder metallurgy and other fields. Widely painted on the surfaces of launders, distribution launders, casting table linings, filter boxes, adapter plates, casting and rolling nozzle materials, scum skimmers, ladles, etc., to protect molds from corrosion and prolong the service life of refractory materials; at the same time During the production process, it prevents fine impurities from penetrating into the molten metal, causing secondary pollution, and greatly improving product quality.It has excellent lubricity and anti-oxidation ability in high temperature environment. The unique physical and chemical properties of boron nitride can still protect its unique lubricity, non-stick property, anti-seize and anti-metal even at extremely high temperature. Or graphite corrosion and oxidation. In addition to being used for the protection of various refractory materials, it also has excellent chemical corrosion resistance and anti-bonding protection effects.

When using boron nitride coatings, pay attention to:

1. Clean the surface of the protected material, rinse and then spray boron nitride

2. After the new launder is diluted by 1:4, the brush tank/furnace wall is about 23 microns thick; after the old launder is diluted by 1:6, the brush tank/furnace wall is about 20 microns thick.

3. Apply the diluted boron nitride paint to the surface of the material with a sponge (brush, spray gun), or adjust the dilution factor as needed.

4. Dry it at a temperature of about 300°C after coating, and use it after the coating is dry

5. For inaccessible local coatings (such as the inner wall of thin tubes), the coated parts can be immersed in the diluted boron nitride paint, and after taking it out, wait for the excess paint to flow out naturally, and use it after drying.

6. The coating should be uniform, the surface should not gather, and it should not be too thick
