橡胶海绵既承袭了橡胶的弹性体特质,又具有海绵样的柔软、微孔结构。在胶鞋制造上用作胶鞋的中(内)底材料。具体应用有三种:第一种是作为低档胶鞋的内底,与其他部件贴合成型后一次完成硫化,故称一次硫化海绵,因含胶率低、大量掺用再生胶,所以成本低廉而被广泛采用;第二种要经过两次硫化,第一次经平板机大面积硫化、裁切,然后和其他部件贴合成型为整鞋,再进硫化罐硫化。因为
Rubber sponge not only inherits the rubber elastomer characteristics, but also has a sponge-like soft, porous structure. In the manufacture of rubber shoes used in rubber (in) bottom material. There are three specific applications: The first is as a low-end rubber insole, and other parts of the paste after the completion of curing one vulcanized, it is called a vulcanized sponge, because of the low rate of plasticization, a large number of mixed with recycled rubber, so low cost was Widely used; the second to go through two vulcanization, the first large-scale flat-panel curing, cutting, and then paste with other components into the whole shoe, and then into the vulcanization tank vulcanization. because
