硫化锑

黑色或灰黑色粉末，斜方晶体结构。硫化锑是由辉锑矿经过精选和化学提纯而得，为黑色固体粉末。它的熔点比较低，为548℃，高温分解后生成的氧化锑，以及在还原剂存在时生成的金属锑，主要性能：

1、能防止高温时材料的氧化燃烧，保持材料的摩擦稳定性，提高材料的抗烧性能；

2、还能降低有机粘合剂在高温时分解速度，提高材料的使用寿命，起到了高温无机粘合剂和润滑摩擦调整剂的作用。

3、此外硫化锑以及在制动过程中高温反应的硬度都比较低，可以减少摩擦材料制动时产生的噪音和震动。

4、硫化锑具有突出的调节摩擦系数的性能，200℃以下低温润滑，250℃高温稳定摩擦系数，抗衰退。

5、并且国内外有的盘式配方中，发现硫化锑的使用可以起到高温无机粘结剂的作用，从而减少树脂用量。

6、我公司生产的硫化锑粒度为1600目超细粒度，能增加产品流动性，提高产品比表面积，使用更充分。

Antimony sulfide

Black or grayish black powder with rhombic crystal structure. Antimony sulfide is a black solid powder obtained from stibnite after cleaning and chemical purification. Its melting point is relatively low, which is 548 ℃. The antimony oxide formed after high temperature decomposition and the metal antimony generated in the presence of reducing agent are as follows

1. It can prevent the oxidation and combustion of the material at high temperature, maintain the friction stability of the material, and improve the burning resistance of the material;

2. It can also reduce the decomposition speed of organic adhesive at high temperature, improve the service life of the material, and play the role of high temperature inorganic adhesive and lubricating friction regulator.

3. In addition, the hardness of antimony sulfide and high temperature reaction during braking is relatively low, which can reduce the noise and vibration of friction materials during braking.

4. Antimony sulfide has outstanding performance of adjusting friction coefficient, lubricating at low temperature below 200 ℃, stable friction coefficient at high temperature at 250 ℃, and anti degradation.

5.It is found that the use of antimony sulfide can play an important role in high temperature inorganic binder, thus reducing the amount of resin.

6. The particle size of antimony sulfide produced by our company is 1600 mesh, which can increase the fluidity and specific surface area of the product and make it more fully used.

The product can obviously improve the adhesion, stabilize the friction coefficient, maintain the smooth and comfortable braking process, reduce the dual surface damage and braking noise, and reduce the wear rate.

铬铁矿

铬铁矿粉具有较好的低温和高温增摩效果，也能起到清扫对偶的作用。细粒度的铬铁矿添加于刹车片中能起到很好的增摩作用，而不刮伤对偶和产生噪音。在摩擦材料中常用的铬铁矿粉的cr203，含量为25%-45%，cr203含量越高，增摩效果也越大。使用时应注意控制其用量和粒径。合宜的用量应不超过7%，粒径细度在325目以上。过多的用量和过粗的粒径固然能提高摩擦系数但也会导致摩损明显增大。

Chromite powder has good friction increasing effect at low temperature and high temperature, and can also play a dual role in cleaning. The addition of fine-grained chromite to the brake pad can increase the friction without scratching and noise. The content of Cr203 in chromite powder is 25% - 45%. The higher the content of Cr203, the greater the friction effect. The dosage and particle size should be controlled. The suitable dosage should not exceed 7%, and the particle size and fineness should be above 325 mesh. Excessive amount and coarse particle size can improve the friction coefficient, but also lead to the obvious increase of friction loss.
