铁路设备钥匙支架喷砂用白色氧化铝砂40目

喷砂用白刚玉砂选用充分冶炼结晶的白刚玉固定炉料，经过破碎、筛分等工艺生产而来。喷砂用白刚玉的粒径范围经过严格控制，使磨粒大小控制在一定范围内。喷砂后产生表面一致的粗糙度。白刚玉韧性好，研磨能力强，自锐性好，喷射到喷砂工件表面时，通过气流的冲击力，工件撞击出凹痕。钝化后的喷砂表面有利于后续喷漆的油漆保持把持力。白刚玉喷砂磨粒还具有喷砂效率高，利用率高的优点。

WFA Abrasive blasting media is made of 99% aluminum oxide powder as raw material, which is refined and crystallized by electric melting (thus white corundum is also called fused alumina and white fused alumina). The white corundum sand produced by our factory has high purity, low impurities, low sodium content, uniform particles and high whiteness.

白刚玉的主要性能特点：

1. 白刚玉显微硬度20.58Gpa,维氏硬度2200-2400kg/mm2，莫氏硬度9.0。可喷砂于大部分金属、铸钢件、铸铁件、有色金属合金材料、含铬含锰含钨钼金属、玻璃和其他非金属材料。

2. 白刚玉研磨能力强，喷砂效率高，由于具有很强的自锐性 ，不会对喷砂表面造成烧*氧化。

3. 白钢玉还可以直接用于研磨抛光，表面处理，喷砂除锈等领域，可用于干式和湿式喷砂，表面抛毛抛光，喷涂前表面处理钝化等领域。

4. 白钢玉氧化铝的纯度高，主要晶相时α相的氧化铝。杂质少，磁性物含量低，喷砂后不会产生化学残留，可用于医药、航空、食品领域机械部件的喷砂。

Characteristics of white fused corundum:

1. Because the white fused alumina has good self-sharpening, strong toughness, strong grinding ability, hardness higher than brown corundum, and low heat generation, it can not only be used as a raw material for abrasive tools such as cutting discs and grinding wheels.

2. White fused corundum can also be directly used in grinding and polishing, surface treatment, sandblasting and rust removal, and can be used in dry and wet sandblasting, surface polishing and polishing, and surface treatment before spraying.

3. Fused alumina sand has strong wear resistance, so it is suitable as an additive material for wear-resistant products.

4. White fused corundum has high refractory temperature, acid and alkali corrosion resistance, and good thermal performance. It can be used as high temperature resistant materials such as casting surface sand, thermally conductive ceramics, and high temperature resistant glue. It is widely used in casting, steel refractory, chemical refractory, 95 batteries, decorative porcelain and other special ceramics and porcelain for daily life, as well as high-tech industries such as semiconductors and electronics.

Applications of WFA Abrasive blasting media:

1. Metal sandblasting surface treatment:

Removing the oxide layer of metal, stainless steel, aluminum alloy, tungsten molybdenum, copper products and other materials. Abrasive sandblasting to remove rust. White aluminum oxide grain has strong grinding ability and high efficiency. It can be recycled and will not leave residues on the surface of the workpiece. White aluminum oxide grain does not contain iron, sulfur, chlorine and other elements. It can be used in dentistry, food, medical equipment, aerospace and other fields :

i. -Surface treatment before spraying for spraying, painting, supersonic thermal spraying, etc., to increase the unevenness of the surface of the material and enhance the holding power of the sprayed material. B-Prepare the surface treatment before painting the back panels of mobile phones and laptops.

ii.-Surface treatment before metal spray welding and titanium plating, such as sandblasting on the surface before brazing of super-hard grinding wheel and cemented carbide.

2. Surface treatment of glass and non-metallic materials:

i. Colored glass, glass products, ceramic products, bamboo chips, wood products, composite non-metallic materials and other materials such as sandblasting, matting, polishing, matte treatment, etc. Rubber materials such as printing rubber rollers, rubber molds, PU materials, acrylic sheets, plastics and other materials are surface-etched.

3. Semiconductor industry: White aluminum oxide used for surface treatment of aluminum alloy semiconductor components, surface treatment and sandblasting before vacuum sputtering; removal of impurities on the back of wafers.

4. Mold processing industry: White aluminum oxide blasting media for surface treatment of metal molds, forged steel molds, forged aluminum molds, mold steel, carbon steel, and mold processing industries such as matte surface treatment after mold biting. For example, wire cutting molds, glass molds, tire molds, conductive rubber molds, shoe molds, bakelite molds, electroplating molds, button molds, plastic product molds and other molds all use alumina sand.

5.Skin cleaning:Microdermabrasion Crystals white aluminum oxide could improve scars,blackheads,pore size. It makes skin smooth and clean without any contaminant.
