GB2477-83標(biāo)準(zhǔn)白剛玉W14研磨粉對(duì)應(yīng)GOST-M14/電熔氧化鋁JIS1200#用于涂料行業(yè)，因其耐磨性好，吸油率低，硬度高等優(yōu)點(diǎn)，廣泛用于涂料填料。電熔氧化鋁是將純度99%含量的工業(yè)氧化鋁粉在電弧爐里經(jīng)2050度高溫熔融冶煉結(jié)晶而來，因此電熔氧化鋁又被稱為電熔剛玉。電熔氧化鋁純度高、自銳性好、耐酸堿腐蝕、耐高溫、熱態(tài)性能穩(wěn)定它硬度略高于棕剛玉，韌性稍低，切削力強(qiáng)。

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

GB 2477-83標(biāo)準(zhǔn)白剛玉W14研磨粉對(duì)應(yīng)GOST-M14/電熔氧化鋁JIS1200#的主要性能特點(diǎn)：

在涂料產(chǎn)品中的配方中，除了樹脂基料以外，往往會(huì)添加一些填料起到填充、調(diào)節(jié)涂料相關(guān)性能等作用。作為涂料的填充材料，需要符合以下幾個(gè)基本要求：

1. 白度要高。不能影響涂料基料和顏料的顏色調(diào)配。

2. 分散性好。易分散的填料不僅可以降低涂料生產(chǎn)時(shí)分散填料的時(shí)間和成本，而且有利于涂料性能的發(fā)揮。

3. 化學(xué)穩(wěn)定性和惰性。填料不會(huì)與涂料中的基料、顏料和其他填料發(fā)生反應(yīng)。

4. 吸油率要低。低吸油率有利于提高涂料的臨界顏料體積濃度，節(jié)約樹脂基料。同時(shí)，與市場(chǎng)上主流的其他低吸油的顏料相匹配。

5.填料的粒度要準(zhǔn)確，粒度范圍要盡量窄、盡量的集中。粒度窄的填料粉末能在涂料中起到空間位隔作用，使涂料中的各種材料顆粒更加均勻地分布。有助于保持涂料的性能一直性。

6. 流動(dòng)性。良好的流動(dòng)性（流平性），可以防止涂料在放置和存貯時(shí)不產(chǎn)生沉淀，有利于涂料的施工。

7. 比表面積適當(dāng)，比表面積影響涂料的黏度、流動(dòng)性、分散穩(wěn)定性、沉降度和吸油量等性能指標(biāo)。

The main performance characteristics of white fused aluminapowder：

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

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

2. Good dispersion. Easy to disperse fillers can not only reducethe 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 withsubstrates, pigments, and other fillers in the coating.

4. The oil absorption rate should be low. Low oil absorption rateis beneficial for increasing the critical pigment volumeconcentration of coatings and saving resin base materials. At thesame time, it matches with other mainstream low oil absorptionpigments in the market.

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

6. Li Good fluidity (leveling) can prevent coatings fromsettling during placement and storage, which is beneficial for theapplication of coatings.

7. The specific surface area is appropriate, as it affectsperformance indicators such as viscosity, fluidity, dispersionstability, sedimentation, and oil absorption of the coating.
