铝氧化物 a氧化铝粉 超细耐磨高熔点氧化铝粉 润滑剂氧化铝粉

氧化铝粉是采用一级工业氧化铝、氢氧化铝外加添加剂技术，低温转相煅烧后，再采用先进的粉磨技术及工艺，生产出的白色活性氧化铝微粉，其特点是粒度均匀，易于分散，化学性能稳定，高温收缩性能适中，具有良好的烧结性能转化率高、钠含量低。特别适用于定型制品和耐火浇注料、可塑料、修补料、喷补料、涂抹料等不定形耐火材料，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。

1、高填充性； 其粒子球形度高、粒度分布宽、可对橡胶、塑料进行高密度填充，可得到粘度低、流动性好的混合物。如添加到各种丙烯酸树脂，聚氨酯树脂，环氧树脂，树脂，硅丙乳液等树脂的水性液体中，添加量为5
到10
，可以提高树脂的硬度，硬度可达6-8H。

2、高导热率；其可高密度填充，与结晶 相比，可得到热传导率高、散热性好的混合物。

3、低磨损性；其外观为球形，对混炼机、成型机及模具等设备的磨损大大降低，可延长设备的使用寿命。

目前我国氧化铝粉的主要用途有：散热片、散热油脂；半导体封装树脂用填充剂；有机硅散热粘结剂混合物用填充剂；陶瓷过滤器；同时氧化铝粉还可以做各种玻璃涂层材料，宝石，精密仪器材料等等。

1、散热片、散热基板用填充剂（MC基板）、导热硅脂、相变化片。

2、半导体封装树脂用填充剂，可制作高压绝缘子及电缆电线，具有耐电弧、抗漏电、高温的灼烧分解出的气体对人畜无害，是优良的环保填料。

3、有机硅散热粘结剂及混合物用填充剂。

4、应用于人造大理石（仿大理石）板材及玛瑙和玉石。可做 厨具、厨柜、餐具及豪华娱乐厅和 会议厅、装饰板材陶瓷过滤器等。

5、高铝耐火材料、陶瓷器件、汽车用火花塞及抛光研磨等制品的原料。

6、生产高铝质不定形耐火材料的基本材料，是增强耐火制品性能的优质填充料。

Alumina powder is introduced
Alumina powder is using industrial alumina, aluminum hydroxide plus additive technology, low temperature phase inversion after calcining, again USES the advanced grinding technology and process, produce white activated alumina powder, is characterized by particle size uniform, easy to disperse, stable chemical performance, high temperature shrinkage performance is moderate, has a good sintering performance high conversion rate, low sodium content.Particularly applicable to finalize the design product and refractory castable, plastic, repair materials, gunning materials, daub materials such as monolithic refractories, to improve the refractory material of high temperature strength, improve the erosion resistance of has a strong role.
Alumina powder characteristics
1, high filling;Its particle spherical degree is high, wide particle size distribution, high density of rubber, plastic filler, low viscosity, liquid mixture can be obtained.Added to all kinds of acrylic resin, polyurethane resin, epoxy resin, melamine resin, silicone acrylic emulsion resin, such as liquid water, adding amount of 5 to 10, can improve the hardness of the resin, hardness can reach 6 to 8 h.
2, high thermal conductivity;It can be filled with high density, compared with crystalline silicon powder, high thermal conductivity, heat dissipation good mixture can be obtained.
3, low wear and tear ";Its appearance is spherical, the mixing machine, molding machine and mold equipment wear and tear is greatly reduced, can prolong the service life of equipment.
Alumina powder use
At present, the main purpose of the alumina powder are: heat sinks, heat oil;Semiconductor packaging resin filling agent;Organic silicon thermal binder mixtures with filling agent;Ceramic filter;Alumina powder at the same time also can do all kinds of glass coating material, gem, precision instruments, etc.
1, radiator, radiator substrate with filler (MC), thermal conductivity silicone grease, phase change.
2, with semiconductor packaging resin filling agent, can produce high voltage insulator electric wire and cable, arc resistance, decomposition of the leakage resistance, high temperature burning gas harmless to human and animal, is a good environmental protection packing.
3, organic silicon thermal binder and mixture with filler.
4, applied to artificial marble, imitation marble plank and jade and agate.To do high-grade kitchen utensils and appliances, kitchen cabinets, cutlery and luxurious recreation and luxury hall, dalle ceramic filters, etc.
5, high alumina refractories, ceramic components, automotive spark plugs and polishing abrasive products, such as raw materials.
6, high aluminum monolithic refractories production of basic materials, is to enhance the performance of refractory products of high quality filling material.
