Which one is better for sandblasting, white emery or brown alumina oxide?
White emery and brown alumina oxide have their own advantages and disadvantages for sandblasting, and the specific choice depends on the specific application requirements.
Sandblasting effect of white emery:
White emery has a slightly higher hardness than brown, but its toughness is slightly lower. It has high purity and self-sharpening, strong grinding ability, low heat generation, high efficiency, and is resistant to acid and alkali corrosion and high temperature. It can quickly remove stains and oxide layers during sandblasting, and due to its high hardness and self-sharpening, it can maintain high working efficiency.
Sandblasting effect of brown alumina oxide:
Brown alumina oxide performs well in sandblasting, mainly because of its high hardness and wear resistance. The hardness is level 9, second after diamond, which makes it very effective in removing stubborn stains and oxide layers. It has a higher density, large bulk density, and less dust generated during blasting, which is beneficial to protect the health and safety of operators. In addition, it has good toughness, is not easy to break, and can maintain stable cutting ability during sandblasting.
Application scenarios and effect comparison:
Brown alumina oxide: Suitable for a variety of fields, such as aluminum profiles, copper profiles, glass, washed jeans, precision molds, etc. Its particles are sharp and can quickly hit the surface of objects under a certain pressure, effectively removing stains, oxide layers and dirt. It also has good environmental performance, less dust and less impact on the environment.
White emery: Suitable for grinding metal products such as high-carbon steel and high-speed steel, as well as precision casting and high-grade refractory materials. It has high efficiency and low heat generation during sandblasting, and can maintain high working efficiency.
Environmental performance and safety:
Brown: Non-toxic and harmless, does not contain harmful substances inside, and meets environmental protection requirements. Less dust is generated during the blasting process, reducing environmental pollution and the risk of dust inhalation by the operator.
White: Although white emery also performs well in environmental protection.
In summary, brown alumina oxide and white emery are both excellent sandblasting abrasives, but the specific use situation should be selected according to different situations.
