[Text / Gaogong LED reporter Zhu Chunwei] Mainland China started late in the LED industry. In the past few years, in addition to the upstream procurement and chip manufacturing, the high cost of imported equipment was subject to high procurement costs. The related raw materials have always been dependent on imports, resulting in high costs.

Beijing Guoruisheng Technology Co., Ltd. (hereinafter referred to as “Guo Ruisheng”), which has a capable research and management team consisting mainly of doctors and masters, has been developing for many years and successfully developed polycrystalline diamond slurry (polishing liquid). ), polycrystalline diamond micropowder (polycrystalline diamond) and nanodiamond powder. These products not only fill the domestic gap, but also the performance of the products meets or exceeds the international advanced level. The cost performance is obviously superior to similar foreign products.

As the only manufacturer of polishing liquid and polycrystalline diamond in China, Guoruisheng's products have gradually replaced foreign products in the domestic market in the past few years, and its market share has increased rapidly. It has been exported to Hong Kong, Taiwan, South Korea, Japan, Europe and America. market.

2013 Gaogong LED Lighting Exhibition will be held at Guangzhou Pazhou Poly Plaza from November 25th to 27th. At this exhibition, Guoruisheng will focus on the introduction of polycrystalline diamond powder for sapphire substrate polishing and LED chip polishing in the LED industry. Grinding and polishing consumables such as polycrystalline diamond slurry and silica polishing solution.
