重点是提高丁苯和顺丁的比例,增加品种,改善质量,降低成本,提高负荷,开拓市场,抢占市场。 1.调整顺丁橡胶和丁苯橡胶的比例针对我国丁苯与顺丁橡胶的产能比低(目前为1.1,世界平均水平1.83,美国和日本分别为1.6和2.1),根据我国国情和合成橡胶需求量预测,丁苯橡胶与顺丁橡胶产能比以1.3—1.5为宜,需在现有基础上增加20万t/a左右的丁苯橡胶生产能力。
The key is to increase the proportion of butadiene and cis-butyl, increase variety, improve quality, reduce costs, increase load, open up the market and seize the market. 1. Adjust the ratio of butadiene rubber and styrene-butadiene rubber For our country styrene butadiene and butadiene rubber production capacity ratio is low (currently 1.1, the world average of 1.83, the United States and Japan were 1.6 and 2.1), according to China’s national conditions and synthetic rubber Demand forecast, styrene butadiene rubber and butadiene rubber production capacity ratio of 1.3-1.5 is appropriate, need to increase on the basis of about 200,000 t / a of styrene-butadiene rubber production capacity.
