There are many kinds of sandblasting processes. What kind of emery products are needed? You need to start from the model to the material. There are thousands of types. Therefore, before choosing the emery products you need, you must first determine what kind of metal sandblasting production process you are using. , Whether it is manual sandblasting or mechanical sandblasting, whether it is water belt sanding or dry spraying, there are requirements. There are many kinds of materials for metal sandblasting, such as silicon carbide products, brown corundum products, corundum products, garnet products, white corundum products, quartz sand products, steel shot blasting, black corundum products, glass beads,
etc.
, can be used in metal sandblasting.
The principle of metal sandblasting is very simple. In fact, the compressed air is used to impact the abrasive, or the air carries the abrasive out, so that the product can be quickly and powerfully hit on the workpiece to be processed. The various descriptions are mostly the same. What is needed is to get rid of what is not needed, keep what you want, smooth out the roughness of the product, leave it smooth, and shine.
Commonly used metal sandblasting materials are mostly mineral materials, and plant abrasives or plastic abrasives can be excluded:
1. Silicon carbide products are currently the most expensive sandblasting materials, and the consumption of products is small. The effect is quick, and the price is higher than that of white corundum products. It belongs to the corundum approved by Baidu. In fact, it can only be regarded as a kind of corundum product.
2. The price of white corundum products is relatively high, but the product is actually the best choice for removing some oxide layers and retaining unresponsive special workpieces. Because of its high purity, the price of white corundum products is relatively high. Also slightly more expensive.
3. Brown corundum product, which is the most cost-effective corundum abrasive in the product, is also widely used in sandblasting metal, and has a relatively high adaptability to materials.
4. Quartz sand products, cheap sand blasting and derusting materials, low price and high hardness, can be used in the maintenance of large boilers and the construction of large pipelines.
5. Black corundum products are expensive, and their toughness is far inferior to that of brown corundum. However, if there is demand in the market, it must exist. Most of them are used in cutting wheels of grinding wheels, and few are used in sandblasting.
