Tongchuan Qinhan Ceramic Co., Ltd. (hereinafter referred to as the company) was established in September 2006. It is located in Dongjiahe Circular Economy Industrial Park, Tongchuan City, Shaanxi Province. It has a registered capital of 100 million yuan. It is a professional oil fracturing proppant (ceramic sand) A high-tech enterprise of ceramic sand that integrates production, research, development and application, its products are mainly used in oil and gas field mining fields such as CNPC, Sinopec, and Yanchang Petroleum.

In 2007, the company has successively passed the certification of ISO9001, ISO14001, ISO45001, API (American Petroleum Association), intellectual property standards and integration standards for industrialization and industrialization.

The "Key Preparation Technology Development and Application of High-Strength and Low-Density Ceramics" jointly developed by the company and Shaanxi University of Science and Technology won the third prize of the 2019 China Light Industry Alliance Science and Technology Progress Award. Relying on the "provincial enterprise technology center" and "municipal-level technology innovation center", the company independently developed 40-70 mesh (69MPa) "environmentally friendly high-intensity and low-density pages for shale gas mining. Fracturing ceramic proppant for rock gas, comprehensively utilizes aluminum-containing solid waste to replace high-grade bauxite as the main raw material, achieving a major breakthrough in major technical indicators such as product volume density, apparent density, and crushing rate. It is the earliest in China Manufacturers that achieve mass production of this type of product have significant environmental protection and economic benefits, saving a lot of costs for oil and gas field mining. In 2021, after being evaluated by the China High-Tech Industrialization Research Association, the overall technical level of the company's independently developed "Environmentally friendly high-strength low-density shale gas fracturing ceramic proppant and preparation technology" has reached the international advanced level. This technology was included in the "2022 National Energy-saving Technology Equipment Product Recommended Catalog for Industrial and Information Technology Fields".

The company always adheres to the business purpose of "people-oriented, honest management, quality-oriented victory, building famous brands, independent innovation, and customer satisfaction", and takes technology as the leader, and takes the road of rolling development and develops towards comprehensive and diversified development. Our company will grasp the lifeblood of the times, keep up with the pace of the times, continue to work hard in the manufacturing industry, uphold the manufacturing spirit of developing the country through industry and developing factories through science and technology, and contribute its own strength to the national "14th Five-Year Plan" economic plan.
