White Fused Aluminium Oxide Suppliers In Philippines

Nowadays, China's white corundum products have reached the international advanced level. So how did China's early white corundum develop? Let's look at it together: Sichuan liberated at the end of 1949, and our technicians were in Leshan The production of white corundum began.

At that time, brown fused alumina price had some disadvantages such as slightly poor grinding force and insufficient sand number uniformity, which needed to be continuously improved. With the care and support of the party and government, it played a decisive role in the development of black silicon carbide. Then China entered the first five-year plan. The country's industrial production continued to develop, and the demand for corundum soared.(white fused aluminium oxide suppliers in philippines)

It happened that in early 1956, the state undertook a comprehensive socialist transformation of private enterprises, white fused alumina changed production relations, liberated productivity, and greatly encouraged Workers' enthusiasm and creativity for production have followed with great changes. Because of the natural ore used as aluminum oxide abrasive in the diamond emery produced at that time, it has strong toughness, high uniformity, and strong grinding ability.

(white fused aluminium oxide suppliers in philippines)The black corundum production capacity has been expanded several times, with an annual output of 400 tons of emery, but it still cannot meet the needs of national industrial production and national defense construction. After hard work, the annual output of corundum reached 1,000 tons in 1972, alumina abrasive which basically meets the needs of the national optical instrument industry, electronics industry, machinery industry, geological department and scientific research units.

All units are welcome. At present, there are more than 200 white aluminum oxide smelting enterprises in China, with an annual production capacity of more than 2.2 million tons. There are more than 300 processing sand and fine powder production enterprises with an annual production capacity of more than 2 million tons. In 2012, the utilization rate of aluminum oxide grit capacity in China was less than 45%.(white fused aluminium oxide suppliers in philippines)

About one-third of the smelting companies have a production line for processing fine sand powder. pink corundum processing sand powder production enterprises are mainly distributed in Henan, Shandong, Jiangsu, Jilin, Heilongjiang and other provinces. The earliest optical factory in China was the Kunming Optical Instrument Factory, brown fused alumina manufacturer which was established in January 1939. It was the only optical factory in China at that time.

(white fused aluminium oxide suppliers in philippines)Since the founding of the country, silicon carbide abrasive has been developed in China for more than 60 years. There are 28 types of diamond embers and specifications in Zengjiadong, and the quality of silicon emery is significantly improved. As a result, the development of diamond abrasives in China has continued to grow. Of course, white fused alumina suppliers it also includes abrasives for polishing optical glass-silicon carbide. This is all caused by industrial backwardness. 

All machinery, equipment, tools, and materials were imported from abroad. The earliest material used as corundum was an iron ore used by craftsmen for coarse grinding of jade. The hardness and other indicators are in line with the raw materials for optical corundum. Before, people used this black fused alumina material to have good appearance, color, corners, etc., and the physical properties such as strength, hardness, and grinding force were not bad.(white fused aluminium oxide suppliers in philippines)

The use effect was similar to the grinding effect of imported similar green silicon carbide. The technology level in the 1940s was unable to screen out the fine silicon carbide used for the fine grinding of lenses in optical factories, and it could only be classified by precipitation classification. However, white fused alumina manufacturer how to screen was a difficult problem for the technicians in China at that time, so it was only possible to use trials for trial production .
