高鋁粉簡介：

高鋁粉，采用優(yōu)質(zhì)鋁礬土，經(jīng)高溫煅燒、水洗、人工精選、破碎、磁選等工序精制而成，將塊狀煅燒鋁礬土加工成4-6目、6-10目、10-20目、20-40目、40-70目粒粒均勻高鋁砂。砂子再經(jīng)球磨機(jī)加工6-10小時以上加工成100-200目、200-325目、325-400目高鋁細(xì)粉。部分高鋁粉材料還經(jīng)過酸洗等特殊處理，進(jìn)一步保證了高鋁粉品質(zhì)，減少雜質(zhì)含量。

Brief introduction of high alumina powder:

High alumina powder is made from high quality bauxite, refined by high temperature calcination, water washing, manual selection, crushing and magnetic separation. The block Calcined Bauxite is processed into 4-6 mesh, 6-10 mesh, 10-20 mesh, 20-40 mesh and 40-70 mesh grain uniform high alumina sand. The sand is processed for more than 6-10 hours by ball mill into 100-200 mesh, 200-325 mesh and 325-400 mesh high alumina powder. Some high alumina materials are also treated with special treatment, such as acid washing, to further ensure the quality of high aluminum powder and reduce the content of impurities.

高鋁粉特性：

高鋁粉膨脹系數(shù)小，耐火度高達(dá)1600-1750度，化學(xué)性質(zhì)穩(wěn)定，使用環(huán)保，無有害氣體排出，可替代其他非環(huán)保價格昂貴的鑄造材料。

High aluminum properties:

High alumina powder has small expansion coefficient, high refractoriness of 1600-1750 degrees, stable chemical properties, environmental protection and no harmful gas discharge. It can replace other non environmental and expensive foundry materials.

高鋁粉理化指標(biāo)：

高鋁粉用途：

  我公司生產(chǎn)的高鋁礬土砂（粉）屬高級耐火材料。適用于熔模鑄造用面層涂料及撒砂料，同時也可作為其它各種鑄造涂料的耐火骨料。

1、煉鋁工業(yè)。用于國防、航空、汽車、電器、化工、日常生活用品等。

2、精密鑄造。礬土熟料加工成細(xì)粉做成鑄模后精鑄。用于軍工、航天、通訊、儀表、機(jī)械及醫(yī)療器械部門。高鋁粉廣泛應(yīng)用于鑄造樹脂類、涂料類、造型砂類、鑄造輔助材料及耐火材料等。高鋁粉用于精密鑄造，制殼的優(yōu)點：不沉淀，拉力強(qiáng)，粘度大，粒度均勻，耐火度高，鑄件表面光潔度好易清砂，型殼耐用等。

3、用于耐火制品。高鋁礬土熟料耐火度高達(dá)1780℃，化學(xué)穩(wěn)定性強(qiáng)、物理性能良好。

4、用于制作耐火搗打料，澆注料，可塑料等，澆注盛鋼桶整體桶襯效果甚佳。

5、制造礬土水泥，研磨材料，陶瓷工業(yè)以及化學(xué)工業(yè)可制鋁的各種化合物。

High aluminum powder use:

The high alumina bauxite (powder) produced by our company belongs to the advanced refractory material. It is suitable for surface coating and sand sanding for mold casting, and can also be used as refractory aggregate for all kinds of casting coatings.

1. Aluminum smelting industry. It is used for national defense, aviation, automobile, electrical appliances, chemical industry, daily necessities and so on.

2. Precision casting. The bauxite clinker is processed into fine powder to make the mold after casting. It is used in military, aerospace, communication, instrument, machinery and medical equipment departments. High alumina powder is widely used in casting resins, coatings, molding sand, casting auxiliary materials and refractory materials. High precision casting for aluminum shell, advantages: no precipitation, strong tension, viscosity, particle size uniformity, high refractoriness, good surface finish casting sand shell, durable etc..

3. Used for refractory products. The refractoriness of high alumina bauxite clinker is up to 1780 C, strong chemical stability and good physical properties.

4, for the production of refractory ramming material, casting material, plastic, casting ladle lining the whole barrel effect.

5, the manufacture of alumina cement, grinding material, ceramic industry and chemical industry can make aluminum compounds.
