飛機蒙皮噴漆前處理用電熔氧化鋁砂36#/46#白剛玉砂

飛機蒙皮噴漆前處理用電熔氧化鋁砂36#/46#白剛玉砂選用充分冶煉結晶的白剛玉固定爐料，經過破碎、篩分等工藝生產而來。噴砂用白剛玉的粒徑范圍經過嚴格控制，使磨粒大小控制在一定范圍內。噴砂后產生表面一致的粗糙度。白剛玉韌性好，研磨能力強，自銳性好，噴射到噴砂工件表面時，通過氣流的沖擊力，工件撞擊出凹痕。鈍化后的噴砂表面有利于后續噴漆的油漆保持把持力。白剛玉噴砂磨粒還具有噴砂效率高，利用率高的優點。

Wjite al Oxide F36/F46 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.

白剛玉的主要性能特點：

1. 白剛玉顯微硬度20.58Gpa,維氏硬度2200-2400kg/mm2，莫氏硬度9.0。可噴砂于大部分金屬、鑄鋼件、鑄鐵件、有色金屬合金材料、含鉻含錳含鎢鉬金屬、玻璃和其他非金屬材料。

2. 白剛玉研磨能力強，噴砂效率高，由于具有很強的自銳性 ，不會對噴砂表面造成燒*氧化。

3. 白鋼玉還可以直接用于研磨拋光，表面處理，噴砂除銹等領域，可用于干式和濕式噴砂，表面拋毛拋光，噴涂前表面處理鈍化等領域。

4. 白鋼玉氧化鋁的純度高，主要晶相時α相的氧化鋁。雜質少，磁性物含量低，噴砂后不會產生化學殘留，可用于醫藥、航空、食品領域機械部件的噴砂。

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.
