Three. Characteristics of aluminum oxide powder:

Aluminum oxide powder has the characteristics of high purity, high melting point, good thermal stability, great importance, low dosage, high hardness, good electrical insulation, acid and alkali resistance, corrosion resistance and so on.

四、氧化铝粉用途:

  氧化铝抛光粉经过高温煅烧过的α-Al2O3粉体,另外含有分散剂、悬浮剂、润滑剂、乳化剂等辅助成份,广泛应用在导热、抛光、电镀、催化剂等行业。

1、氧化铝粉特别适用于定型制品和耐火浇注料、可塑料、修γ补料、喷补料、涂抹料、结合剂、高纯耐火纤维等不定形耐火材料,对改善耐火材料的高温强度、提高材料的抗侵蚀性能具有很强的作用。

2、氧化铝粉具有真比重大、硬度高、耐磨性好、耐冲击等特点,用于机器制备,光学加工,餐具行业,饰品加工,汽车配件修理维护,光学镜片,机器电器配件等等需要表面处理抛光研磨的行业。

3、氧化铝粉用于制镶牙水泥、瓷器、特种陶瓷、电子陶瓷、油漆的填料、媒染剂、金属铝等。可添加到各种水性树脂、油性树脂内、环氧树脂、丙烯酸树脂、聚胺酯树脂、塑料、橡胶中,添加量为3%-5%,可以明显提高材质的硬度,硬度可达6-8H甚至更高。

Four. Use of aluminum oxide powder:

Alumina polishing powder has been calcined by high temperature and has auxiliary components such as dispersant, suspending agent, lubricant and emulsifier. It has been widely applied in heat conduction, polishing, electroplating, catalyst and other industries. -Al2O3 powder has been calcined at high temperature.

1, alumina powder is especially suitable for shaping products and refractory castable, plastic repair, gamma feeding, gunning material, coating material, binder, high purity refractory fiber and other unshaped refractory materials, has a strong effect on improving high temperature strength and improve the anti erosion properties of refractory materials.

2, alumina powder is really heavy, high hardness, good abrasion resistance, impact resistance and other characteristics, is used for machine preparation, optical processing, tableware industry, jewelry processing, repair and maintenance of auto parts, optical lens, electrical machine accessories and so on need polishing the surface treatment industry.

3, alumina powder used for dental cement, ceramics, special ceramics, electronic ceramics, paint filler, mordant, aluminum etc.. It can be added to all kinds of waterborne resins, oleoresin, epoxy resin, acrylic resin, polyurethane resin, plastic and rubber. The addition amount of 3%-5% can obviously improve the hardness of materials and the hardness can reach 6-8H or even higher.
