GB 2477-83标准白刚玉W14研磨粉对应GOST-M14/电熔氧化铝JIS1200#

GB 2477-83标准白刚玉W14研磨粉对应GOST-M14/电熔氧化铝JIS1200#用于涂料行业，因其耐磨性好，吸油率低，硬度高等优点，广泛用于涂料填料。电熔氧化铝是将纯度99%含量的工业氧化铝粉在电弧炉里经2050度高温熔融冶炼结晶而来，因此电熔氧化铝又被称为电熔刚玉。电熔氧化铝纯度高、自锐性好、耐酸碱腐蚀、耐高温、热态 性能稳定它硬度略高于棕刚玉，韧性稍低，切削力强。

 White corundum is used in the coating industry and is widely used as a filler in coatings due to its advantages of good wear resistance, low oil absorption rate, and high hardness. Electromelted alumina is a type of industrial alumina powder with a purity of 99%, which is crystallized by melting and smelting at a high temperature of 2050 degrees in an electric arc furnace. Therefore, electromelted alumina is also known as electromelted corundum. Electromelted alumina has high purity, good self sharpening, acid and alkali corrosion resistance, high temperature resistance, and stable thermal performance. Its hardness is slightly higher than that of brown corundum, with slightly lower toughness and strong cutting force.

GB 2477-83标准白刚玉W14研磨粉对应GOST-M14/电熔氧化铝JIS1200#的主要性能特点：

在涂料产品中的配方中，除了树脂基料以外，往往会添加一些填料起到填充、调节涂料相关性能等作用。作为涂料的填充材料，需要符合以下几个基本要求：

1. 白度要高。不能影响涂料基料和颜料的颜色调配。

2. 分散性好。易分散的填料不仅可以降低涂料生产时分散填料的时间和成本，而且有利于涂料性能的发挥。

3. 化学稳定性和惰性。填料不会与涂料中的基料、颜料和其他填料发生反应。

4. 吸油率要低。低吸油率有利于提高涂料的临界颜料体积浓度，节约树脂基料。同时，与市场上主流的其他低吸油的颜料相匹配。

5. 填料的粒度要准确，粒度范围要尽量窄、尽量的集中。粒度窄的填料粉末能在涂料中起到空间位隔作用，使涂料中的各种材料颗粒更加均匀地分布。有助于保持涂料的性能一直性。

6. 流动性。良好的流动性（流平性），可以防止涂料在放置和存贮时不产生沉淀，有利于涂料的施工。

7. 比表面积适当，比表面积影响涂料的黏度、流动性、分散稳定性、沉降度和吸油量等性能指标。

The main performance characteristics of white fused alumina powder：

In the formulation of coating products, in addition to resin based materials, some fillers are often added to fill and regulate the related properties of the coating. As a filling material for coatings, it needs to meet the following basic re:

1. The whiteness should be high. It should not affect the color mixing of the coating base material and pigment.

2. Good dispersion. Easy to disperse fillers can not only reduce the time and cost of dispersing fillers during coating production, but also facilitate the performance of coatings.

3. Chemical stability and inertness. Fillers will not react with substrates, pigments, and other fillers in the coating.

4. The oil absorption rate should be low. Low oil absorption rate is beneficial for increasing the critical pigment volume concentration of coatings and saving resin base materials. At the same time, it matches with other mainstream low oil absorption pigments in the market.

5. The particle size of the filler should be accurate, and the particle size range should be as narrow and concentrated as possible. Narrow particle size filler powder can play a spatial segregation role in coatings, making various material particles in the coatings more evenly distributed. Helps maintain the consistency of paint performance.

6. Li Good fluidity (leveling) can prevent coatings from settling during placement and storage, which is beneficial for the application of coatings.

7. The specific surface area is appropriate, as it affects performance indicators such as viscosity, fluidity, dispersion stability, sedimentation, and oil absorption of the coating.
