    • A porous pipe primarily of rubber and synthetic rubber reclaimed from rubber tires, ground to a relatively small granular size, with metal removed; such as, for example, would pass through a 30-mesh screen, process-mixed through a pipe extruder, with a much smaller binder mix of primarily polyethylene, along with vinyl, ABS binder, and a trace of attaclay. The resulting product is useful as a subsurface irrigation buried pipe, having high structural integrity effectively resisting soil-loading pipe collapse, and it even resists collapse from moderately large rocks in the soil, and yet has a high degree of flexibility along its length. A pipe is provided with cross sectional area of pipe wall more than twice the cross sectional area of the pipe opening. It is a waterleaking pipe formed in the process through the extruder with limited foaming from steam originating from absorbed moisture in the ground, reclaimed rubber tire material, and from residual gasses venting from the material mix, with product mix heating in the extruder, forming some open cell fluid flow paths. The foaming with steam and gasses from the mix also form labyrinth passageways between the rubber tire granuals and the polyethylene binder mix, and also through the binder mix that is non-compatible with the rubber granules but that forms a physical interconnective structural material binder therefor.
    • 主要由橡胶轮胎回收的橡胶和合成橡胶的多孔管,研磨成相对较小的颗粒尺寸,金属被去除; 例如,将穿过30目筛,通过管式挤出机进行加工混合,其中主要是聚乙烯的粘合剂混合物以及乙烯基,ABS粘合剂和痕迹。 所得产品可用作地下灌溉埋管,具有高度的结构完整性,有效抵抗土壤加载管塌陷,甚至抵抗土壤中大块岩石的塌陷,但在其长度上具有高度的柔韧性。 管道设有管壁的横截面积超过管道开口横截面面积的两倍。 这是一个通过挤出机在该过程中形成的起泡管,其具有来自地下吸收的水分的蒸气的有限的发泡,再生橡胶轮胎材料以及从材料混合物排出的残留气体,在挤出机中产物混合物加热,形成一些 开放细胞流体流动路径。 来自混合物的蒸汽和气体的发泡也在橡胶轮胎颗粒和聚乙烯粘合剂混合物之间形成迷宫通道,并且还通过与橡胶颗粒不相容的粘合剂混合物,但形成物理互连结构材料粘合剂。

    • The invention is to apparatus and method for a plasticizing batch process used in manufacturing building materials such as sheet goods, roofing shingles, and various sizes of dimensional lumber products. Recycled waste plastics and other not plastic materials are used in a batch process to plasticize the waste materials into a mixture used in molding various products. A intensive mixture mixes and plasticizes the waste materials of a predetermined weight until the plasticized mixture reaches a predetermine temperature. The material is then expelled to a material mover to dispense the plasticized material by weight to molds in which the plasticized material is pressed to form various products.
    • 本发明是用于制造建筑材料如片状物,屋顶瓦和各种尺寸的木材制品的塑化分批法的装置和方法。 循环使用的废塑料和其他不是塑料材料用于分批处理,以将废料塑化成用于模制各种产品的混合物。 强化混合物混合并塑化预定重量的废料,直到增塑混合物达到预定温度。 然后将材料排出物料移动器,以将塑化材料按重量分配到其中压制塑化材料以形成各种产品的模具。
