本方法是为了适应各种不同的筛面宽度要求而加以改进的弹性筛板的制造法。碎石场等使用的振动筛,从隔音性能及寿命方面考虑,多采用聚氨酯合成树脂材料制成的多孔弹性筛板。但是,过去制造这种弹性筛板的方法,主要是采用模子加压硫化的方法,有时电采用浇入热塑性树酯材料的方法。这种方法,也要使用模子,其宽度至少要和筛分机筛面的大小适应,这包括网眼成形在内的整个外形的成形制造。因此,这种制作方法,只能用模子的尺寸来决定一定规格大小的弹性筛板。但是,筛分 This method is to adapt to a variety of different screen width requirements and to be improved elastic sieve manufacturing method. Vibrating screen used in gravel field, etc., from the noise performance and life considerations, the use of polyurethane synthetic resin porous material made of porous sieve. However, in the past, the method of manufacturing such an elastic screen was mainly a method of press-vulcanizing molds, and the method of pouring a thermoplastic resin material was sometimes used. This method, but also the use of mold, the width of at least the sieve screen size to adapt, including the formation of the entire shape of the mesh forming. Therefore, this production method, only the size of the mold to determine the size of a certain size of elastic sieve. However, screening
