In terms of development momentum, first of all, exports are an important engine for the growth of machinery and equipment manufacturing. In 2010, the growth rate of orders from foreign countries was much higher than that of domestic markets, and the demand for emerging markets such as Asia and South America grew particularly rapidly. Currently, the capacity utilization rate of the industry is maintained at about 88.8%, exceeding the normal level of 85%.
In terms of development trend, the development situation in different branches is different: In the 32 professional branches of machinery and equipment manufacturing, the sales of metallurgical rolling equipment, power systems, electrical automation equipment, and mining equipment have reached 2006 again. -The high level in 2008, but in the field of construction machinery, building materials equipment and printing and papermaking technology, its sales still have some gaps from previous years.
It can be prepared by directly crushing natural calcite, limestone, chalk, shell, etc. by mechanical methods (using Raymond mill or other high-pressure mill). Because the sedimentation volume of heavy Calcium Carbonate is smaller than that of light calcium carbonate, it is called heavy calcium carbonate.
Heavy calcium carbonate is abbreviated as heavy calcium. It uses high-quality limestone as raw material and is processed into white powder by a lime mill. Its main component is CaCO3. Heavy calcium has the characteristics of high whiteness, good purity, soft hue and stable chemical composition. Heavy calcium is usually used as a filler. It is widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc. Increase the volume of products and reduce production costs. Used in rubber, it can increase the volume of the rubber, improve the processability of the rubber, play a semi-reinforcing or reinforcing role, and can adjust the hardness of the rubber.
