This product is a two-component printing ink for photocopiers. It is mainly used for fast fixing on high-speed machines. First, we must master the working principle of the printer and the control principle of filling powder, and then choose the appropriate raw materials for formula design and process design according to the characteristics of OEM powder casting, and carry out production amplification test on the laboratory products to produce high-quality products. In order to produce quality products, the formula and process are the most critical. The ladle alumina magnesia spinel castable in amorphous refractories is all over Handan, Xingtai, Shanxi and other places, and is well received by users for its high quality products. Over the years, the company has won a number of honors, such as "Top 20 Private Enterprises" in Shexian County, the ninth consumer trust unit in Hebei Province, and the integrity show enterprise in Hebei Province. High - grade aluminum homogenizing material, widely used in refractory manufacturing industry, favored by foreign companies. At present, it is necessary to improve the process of sintering high alumina super grade homogenizer. At present, our company is leading in casting steel in China in the fields of power insulation antifouling materials, oil field drilling fluid treatment agent, etc., and our products have filled many market gaps, and we are the leader in the industry with strong competitiveness. In 2010, the total value of the unit assets was RMB 590 million, with sales revenue of RMB 213.45 million, tax paid RMB 3.3737 million and profit RMB 28.83 million. It has the technical, economic and supporting conditions for new projects. A pultrusion production line with carbon fiber composite core was established, and the corresponding pultrusion grinding tools were developed. Outsourcing Processing of Stranded Aluminum Wire with Carbon Fiber Composite Core. The production technology, equipment combination and important technology of carbon fiber composite core material are studied. Construction of carbon fiber composite core material production of 500 km of wire cast steel castings. The production technology and equipment of carbon fiber composite core material were studied.
