我国台湾省台橡股份有限公司是生产SBC热塑性弹性体最早的企业，品种很多，性能很好，产量很大。SBC（丁二烯／苯乙烯嵌段共聚物）是苯乙烯类热塑性弹性体（TPE），包括未充油／充油SBS、SEBS、SIS等类型，具体品种未充油SBS牌号有411／411P、3201／3201P、3202、4202、4230等；SEBS的牌号有3150、3151、3152、3154等；SIS的牌号有1307、2393等。可用于制备SBS装修胶、SBS喷胶、SBS压敏胶、热熔胶、热熔压敏胶、密封胶及沥青、塑料、橡胶改性等。

台橡股份选用密析尔液相微水分析仪

台橡股份有限公司的新工厂主要生产热塑性橡胶原料，可用于汽车零部件、电线电缆、医疗器材以及合成树脂的改性．以及高级跑鞋的生产。通过一系列的产品比较．最近他们正式选用了英国密析尔仪表的LIQUIDEW（液相微水分析仪），通过使用这套微水分析仪．在生产的工艺过程中可实现对液态有机溶剂（丁二烯等）中的微量水份进行监测并精确测量．从而确保产品质量。

Experimental and theoretical study on vibration control of base-isolation with energy transducer

In order to evaluate the effects of structural control and energy transition for the base-isolation with energy transducer （BIET）, shaking table tests on a steel frame model （BIET system） with scale of 1：4 were conducted and the results were compared with the lead rubber beating （LRB） isolation system for the same model. Then numerical analysis of the system was carried out, in which the improved Wen analytic model was used to simulate the hysteretic law of transducers. The results show that the structural system can transform the partial earthquake energy to hydraulic energy ; furthermore, the effect of structural control can reach or be close to that of the LRB isolation system. The agreements between numerical analysis results and those of shaking table tests demonstrate the accuracy of the numerical model.
