According to the petrochemical economic data, in March, the output of PVC was 1.116 million tons, an increase of 7.4% year-on-year. From January to March this year, the cumulative output was 3.277 million tons, a cumulative increase of 9.8%. Statistics on upstream raw materials show that in March, the country’s calcium carbide production was 1.677 million tons, an increase of 13.6% year-on-year. Accumulated production from January to March this year was 4.715 million tons, a cumulative increase of 13.5% year-on-year. In addition, in March, soda ash production was 2.006 million tons, an increase of 7.9% year-on-year, and cumulative production from January to March was 5.796 million tons, a year-on-year increase of 9.1%. In March, the production of alumina downstream of caustic soda was 3.115 million tons, a slight year-on-year increase. From January to March, the cumulative production was 8.943 million tons, an increase of 7.9% year-on-year. According to the latest economic data released, in March 2012, the output of the two main chlor-alkali products, caustic soda and polyvinyl chloride, continued to grow slightly year-on-year. In March, the country's caustic soda production was 2.229 million tons, an increase of 3.7% year-on-year. From January to March this year, cumulative production was 6.243 million tons, a cumulative increase of 5.2% year-on-year. In terms of upstream raw materials, in March, the country’s crude salt output was 3.758 million tons, a slight decrease from the same period of the previous year. From January to March, the cumulative output was 9.846 million tons, an increase of 5.7% year-on-year. Cement grinding aid is a kind of chemical additives can improve cement grinding effect and performance, can significantly improve the cement production, every period cement strength, were to improve its liquidity.Cement grinding aid can greatly reduce the grinding ball phenomenon formed in the process of electrostatic adsorption package, and can reduce the grinding of ultrafine particles in the process of coalescence trend again.Cement grinding aid can significantly improve the liquidity of cement and improve the mill grinding effect and efficiency of classifier choose powder, so as to reduce the energy consumption of grinding.Using grinding agent in the production of cement with a low compaction trend of coalescence, which benefits the loading and unloading of cement, and can reduce the phenomenon of wall hanging cement silo.As a kind of chemical additives, grinding agent can improve the cement particle distribution and hydration, so as to improve the early strength cement and later strength.
