According to the hardness classification, there are two categories of super hard abrasives and ordinary abrasives. Abrasives range from softer household detergents to gem abrasives to the hardest material diamonds. Abrasives are essential for making every precision product. Many natural abrasives have been replaced by synthetic abrasives. In addition to diamond, the performance of natural abrasives is not stable, but still has its value. Abrasives are tools for grinding, grinding and polishing. Most of the abrasive tools are artificial abrasives made of abrasive plus binder, and natural abrasives directly processed from natural mineral rock. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in the processing of food processing, paper industry and non-metallic materials such as ceramics, glass, stone, plastics, rubber, and wood.
In 2017, the amount of imported abrasive products and the amount of products in China have risen and fallen, but without exception, the average import price has increased. According to the statistics of enterprises above designated size of the coated abrasives branch, the sales revenue of coated abrasive products in 2017 reached 6.332 billion yuan, an increase of 8.20% over the same period of 2016. In 2017, the output of coated abrasives reached 560 million square meters, an increase of 9.33% over the same period of 2016; the output value reached 6.53 billion yuan, an increase of 10.16% over 2016; the unit price per square meter reached 11.57 yuan, an increase of 0.86 over the same period of 2016. %.
Although the prospect of the abrasives industry is very bright, it requires constant efforts to achieve good expectations. The reasons for the prospect to be expected are as follows:
1. At present, most of the backbone enterprises in the abrasives industry in China have basically completed the management system reform, the transformation and transformation, and the adjustment and optimization of the industrial structure. They have been integrated into the international competition environment in advance, the foundation of industry development and technological progress. The potential has accumulated.
2. With the development of high-tech industries and the advancement of traditional industrial technologies worldwide, various new materials and processes have been widely used in many important fields. Abrasives are important engineering materials and main processing tools. It shows its importance and indispensability in technological progress.
