白刚玉的概述:
白刚玉是以优质铝氧化粉为原料,经电熔提炼结晶而成,硬度略高于棕刚玉,韧性稍低,纯度高、自锐性好、磨削能力强、发热量小、效***、耐酸碱腐蚀、耐高温热稳定性好。用其制成磨具适用于磨削高速钢,高碳钢等广泛应用于固结磨具,涂附磨具,抛光和精密铸造等行业。并且由于白刚玉经电熔提炼结晶而成,硬度略高于棕刚玉,韧性稍低,纯度高、耐酸碱腐蚀、耐高温热稳定性好,是一种***的耐火材料。
产品粒度按***以及各国标准生产,可按用户要求粒度进行加工。通用粒度号为 F4~F220,其化学成份视粒度大小而不同。突出的特点是晶体尺寸小耐冲击,如果用自磨机 加工破碎,颗粒多为球状颗粒,表面干洁,易于结合剂结合。
白刚玉密度:
密度分为两种,一是白刚玉堆积密度,二是白刚玉真密度。
堆积密度为:1.53~1.99g/cm3,磨料的堆积密度与磨料的粒度,粒度组成,品种,颗粒形状等因素都有关,一般来说,粗粒度磨料比细粒度磨料堆积密度大,混合粒度磨料的堆积密度大于单一的粒度密度。
颗粒密度为:3.95~4.0g/cm3,精铸专用刚玉真密度4.1g/cm3,磨料的真密度是指单位体积(排除开气孔的体积)内所含磨料的质量
基本粒度为:45%~55% ,基本粒度是***研磨效果的重要指标,在生产时应可以适当控制,但生产速度可能放缓。

Summary of white fused alumina.
White fused alumina is a high quality aluminum oxide powder as raw material, the crystal in a fused, slightly higher than the corundum hardness, toughness is a bit low, high purity, good self-sharpening, strong grinding ability, low calorific value, high efficiency, acid and alkali corrosion resistance, resistance to high temperature thermal stability is good. Made with the grinding tool is suitable for the grinding of high speed steel, high carbon steel and so on are widely used in the consolidation abrasive, coated with abrasive, polishing and precision casting and other industries. And because the white corundum crystal in a fused, slightly higher than the corundum hardness, toughness is a bit low, high purity, acid and alkali corrosion, high-temperature thermal stability is good, is a kind of advanced refractory material.
Product size according to the international standards and national standards production, processing granularity according to users requirement. Gm grain sizes for the F4 ~ F220, its chemical composition depending on the size of the particle size. Outstanding characteristic is little impact resistance, crystal size, if use the broken mill processing, particles are spherical particles, the surface dry clean, easy to bond together.
White fused alumina density:
Density is divided into two kinds, one is white fused alumina bulk density, the second is Bai Gang YuZhen density. Of packing density: 1.53 ~ 1.99 g/cm3, abrasive and abrasive granularity of packing density, particle size, varieties, and associated factors such as particle shape are, in general, coarse-grained abrasive abrasive than fine-grained bulk density is big, mixed abrasive granularity of packing density is greater than the single particle density. Of grain density: 3.95 ~ 4.0 g/cm3, in recent years, zhengzhou HuaDi abrasives co., LTD. Precision casting special just YuZhen has reached to 4.1 g/cm3 density, true density refers to the unit volume of abrasive (exclude open pore volume) contains the quality of the abrasive
Basic particle size as follows: 45% ~ 55%, and basic particle size is the important measure to insure the effect of grinding, when production can be properly controlled, but production speed may slow.
White fused alumina properties:
Project metrics

White fused alumina application example:
1, can be used in all kinds of sandblasting, and grind the light (Lapping) homework; 2, glass or acrylic crafts aesthetic feeling of atomization processing; 3, the television screen sandblasting process; 4, the cutting of silicon wafer; 5, teeth cleaning sand; 6, precision casting sand;
White fused alumina scope of application:
White fused alumina is suitable for all kinds of high-end products, technology or beautify processing, hardware and other products surface after sand blasting surface clean without any impurities, cleaning trouble. Fine white corundum used as a polishing. Additives can also be used to do all kinds of products. ___________ surface machining: metal oxide, carbon black, metallic or non-metallic surface rust removal, such as gravity die casting, rubber mold of oxides or removal of the debonding agent, ceramic surface black spots, color removal of uranium, coloured drawing or pattern. This beautify processing: all kinds of gold, K gold, precious metals products of extinction or mist side handle, crystal, glass, corrugated, the fog of the force that press a gram etc. Nonmetal surface processing, and can make the machining surfaces into metallic luster. 3. Processing: etching jade, crystal, agate, semi-precious stones, seal, stone, the stone of jas, antiques, marble tombstone, ceramic, wood, bamboo, etc. The etching of artists. _____ the pretreatment processing: TEFLON, TEFLON, PU, rubber, plastic, coating, rubber ROLLER (ROLLER), electroplating, metal spray welding, plating titanium before processing, increase the surface adhesion. ⒌ burrs processing: bakelite, plastic, zinc, aluminum die-casting products, electronic components, removing burrs of magnetic core, etc. Eliminate the processing.
The advantage of white fused alumina,
1, do not affect the color of the machined part;
2, can be in it is strictly prohibited to iron powder residue of sand blasting process used to;
Level 3, micro powder is very suitable for wet sandblasting and research the light;
4, high processing speed quality;
5, very low amount of iron oxide in suitable for the sand blasting of iron residue is strictly prohibited;
6, after pickling with impurities.
