棕色金刚砂46目堆积密度高颗粒圆整

 

倾倒炉巴马克棕刚玉是以优质倾倒炉棕刚玉为原料,经巴马克磨机粉碎 整形,磁选去铁,筛分成多种粒度,其质地致密、硬度高,粒形成球状,适用于制造陶 瓷、树脂高固结磨具以及研磨、抛光、喷砂、熔模铸造等,还可用于制造耐火材料。其中,棕刚玉粒度砂广泛用于各种喷砂,树脂砂轮磨料,涂附磨具和耐磨方面。

棕刚玉对辊砂(P砂)是通过对辊机生产线加工处理而成,堆积密度比球磨整形砂低,但纯度高,自锐性强.韧性好,磁性物含量特低,用其制成的磨具磨削锋利,发热率低,磨削比高,且使用时沾附少,制成的烧结磨具具有烧成后颇色深蓝、不起网状裂纹、无锈斑的特点,适用于涂附磨具。棕刚玉巴马克砂(巴马克F砂)为巴马克制砂线生产,颗粒形状更加圆整,堆积密度高,氧化铝纯度高,更适用于生产固结磨具例如树脂砂轮、陶瓷砂轮等产品。

Brown fused alumina grit is a basic abrasive grain for making abrasive tools and abrasive blasting. It is produced from natural bauxite mine by a fusing process. After fusing and melting at about 2000 centigrade, it turns to a kind of artificial brown fused alumina. The main chemical of brown fused alumina is Al2O3. So it also be called brown aluminum oxide.

 With different milling technology, there are several types of brown fused alumina. They are available for different applications such as sandblasting, surface treatment,resin bonded abrasives, vitrified bonded abrasives,anti-skid materials,etc. The higher Al2O3 purity, the higher hardness and better grinding performance. 

倾倒炉巴马克棕刚玉和普通棕刚玉的区别:

1.倾倒炉影响SiO2含量,倾倒炉SiO21%,常规固定炉SiO21.5%

2.巴马克影响密度,,巴马克破碎粒型圆润,密度大于颚式破碎机的密度

3.倾倒炉Al2O3含量高,倾倒炉Al2O394%,固定炉Al2O393%

4.倾倒炉工艺生产的棕刚玉韧性好,使用于磨具制品。

 

Features of brown fused aluminum oxide:

1. High hardness around Mohs 9.0.

2. High toughness which is a little higher than white fused alumina.

3. Good grinding ability.

4. A quality level with high Al2O3 purity and low TiO2 impurity.

5. Low Fe2O3 content with magnetic removal treatment.
