Being committed to R&D of calcium carbonate, GuangXi Huana has set up Huana Calcium Carbonate Engineering Researching Center with more than 3,000㎡ labs and three pilot production plants. There is a high-level working team with perfect personnel structure with professors employed as adviser for technology work. Besides many general analytical and testing apparatuses, some advanced instruments and equipment were imported in the department. We established close technological cooperation with several universities, institutes and companies in relation to calcium carbonate. To promote the calcium carbonate industry, many national science and technology programs are being carried out here. In recent years, outstanding achievement was made. 37 technologies were applied and published by GuangXi huana for patent, and 15 technologies were licensed with patent for invention, and 9 technologies were licensed with patent for utility models.
