Foundry Coating's recipe knowledge
Paper pulp waste liquid coating is a kind of water-based coating for lost foam coating, which is usually used in the production of small and medium iron castings and aluminum alloy castings, with good overall effect. Need to pay attention to three points during use. Do you know which ones? Follow the editor of Foundry Coating to have a simple understanding!
1. The paper pulp waste liquid paint needs to be sprinkled with quartz sand after immersion to prevent the paint from falling down.
2. If it is necessary to coat more than two layers of paint, quick drying measures should be taken, otherwise the dried layer of paint will easily deliquesce and fall off, which will affect the operation process.
3. Because there is a certain degree of humidity in the air, even if the dried coating is left in the air for too long, it will absorb moisture. Therefore, companies should try to avoid placing the coating in the air for a long time.
In summary, it is about the formula-related knowledge of Foundry Coating.
