本文以粘合体剥离强度为根据,研究了橡胶硫化时的粘合问题,重点是解决三元乙丙橡胶(EPDM)与聚氯乙烯(PVC)之间的粘合,而它们之间的剥离强度大小系取决于橡胶与聚氯乙烯彼此间的交联度和界面厚度。为了获得橡胶与聚氯乙烯间的一级键,就须将三嗪硫醇加入聚氯乙烯化合物中,对于不饱和橡胶还要加氯醌(CL)之类的氧化剂。如果分别选择种类最优良的三嗪硫醇(TT,三嗪三硫醇)氧化剂,并取最佳用量和最好的硫化条件,结果就可以得到剥离强度较高的粘合体。除此而外,界面的厚度还受增塑剂种类、用量、聚氯乙烯的聚合度、以及不饱和橡胶中所加入的软化剂等影响。这种在硫化时产生的粘合体系也可应用于各种不饱和的含氯橡胶与聚氯乙烯的粘合。

kkI工艺是一项新的联合工艺,它通过流化床热裂化,以减压渣油为原料生产轻质油,同时以沉积炭为还原剂将铁矿石还原成海锦铁。减压残渣油在流化床反应器内,以铁矿石细粉作为流化介质裂解成轻质油。裂解油经过一般蒸馏方法即得到石油产品。被覆盖着一层副产焦炭的铁矿石从反应器内连续取出,然后在还原炉内很容易地被还原成海绵铁。根据减压渣油不同的硫含量,有两种还原方法供选用。硫含量低的可选用旋转炉;而硫含量高的就选用流化床还原炉。从中型实验厂的操作结果来看,石油产品的收率与常规热裂化相差无几。在旋转炉内可以有效地将92％以上的铁矿石还原成海绵铁坯块,而在流化床内。即使使用高含硫量的减压渣油。也可将95％以上的铁矿石还原成含硫量低於0.05％海绵铁。
