    摘要： Systems and methods are provided for making aggregate from comingled waste plastics. For example, there is provided a method of making a preconditioned absorptive resin aggregate, the method including:



    obtaining a supply of granulated mixed plastic waste treated with a preconditioning agent that comprises at least one of calcium oxide and calcium hydroxide; mixing the supply of granulated mixed plastic waste treated with the calcium oxide preconditioning agent with one or more additives to form a plastic waste mixture, the one or more additives comprising pozzolans; hot extruding the plastic waste mixture to form an extruded product comprising waste plastic material; cooling the extruded product; and processing the extruded product to form an aggregate. Products incorporating such aggregates, such as, for example, lightweight construction blocks, are also provided. Also provided are methods of forming a waste plastics feedstock.

    摘要： A deodorization method and apparatus are disclosed to eliminate, reduce or correct the odour of incoherent plastics, i.e. in the form of granules and/or microgranules and/or powder and/or flakes or the like, with a container of the incoherent plastics, an actuator for generating a process gas flow from a gas inlet to a gas outlet of said container, an olfactory sensor arranged to detect odorous emissions in the process gas exiting from said container, a controller configured to control at least one parameter of the process gas on the basis of an odour intensity measured by said olfactory sensor, with the aim of eliminating the substances that cause undesired odours from the incoherent plastics that is usable in a transformation process to make an end product.

    摘要： Provided is a treatment method for fluororesin pellets to remove hydrofluoric acid released from fluororesin pellets obtained by melt-molding a melt-moldable fluororesin. The treatment method comprises bringing a hydrofluoric acid-removing medium selected from warm water of from 30 to 200° C., steam of from 100 to 200° C. and warm wind of from 40 to 200° C. into contact with fluororesin pellets obtained by melt-molding a melt-moldable fluororesin, and thereby treating the fluororesin pellets so that the amount of hydrofluoric acid released per kg of the resulting fluororesin pellets would be at most 5 μg as determined after the storage of the resulting fluororesin pellets at 35° C. for 15 days.

    摘要： This disclosure relates to pelletized polyolefin resins. More particularly, the disclosure relates to a process that allows for adjustment of certain desired properties of either the resin, such as modification of the bulk density of resin pellets, or adjustment of properties for the articles made from the resin, such as improved odor and taste properties, when used as a bottle cap, for example, or tailoring of the resin volatile or wax level, when used to make pipe, for example. This disclosure also relates to a system for making pelletized resins, such as mono-modal or multi-modal olefin polymer resins.

    摘要： A process and apparatus for the purging of excess hydrocarbons or monomer from polymer materials using a settled bed non-fluidized conditioning vessel having an internal gas distribution system which insures uniform gas distribution within the vessel and solids bed and provides for mass flow of solids. The gas distributor consists of several pipes or distribution legs configured parallel to the converging hopper walls of the vessel, having gas injection ports along their axial length. The injection ports are located so that the gas is evenly distributed across the cross section of the vessel at the level of the port. The size of the ports may be varied along with the spacing between ports such that specified pressure drops occur across any cross section of the vessel. The invention may be applied externally to a vessel such that the gas distribution legs enter through the vessel walls, or inserted entirely within the vessel, or even attached to the internal walls. The manifold and gas distribution legs are continuous and non-partitioned to allow a continuous gas stream to enter the vessel through the gas injection ports. The invention may also be used as a retrofit for existing bulk process vessels.

    摘要翻译： 用于使用具有内部气体分配系统的沉降床非流化的调节容器从聚合物材料中清除过量的烃或单体的方法和装置，其确保在容器和固体床内均匀的气体分布并提供固体的质量流动。 气体分配器由几个配置成与容器的会聚料斗壁平行的分配管组成，具有沿其轴向长度的气体注入口。 注入口位于这样的位置，使得气体在端口的水平面上均匀分布在容器的横截面上。 端口的尺寸可以随着端口之间的间隔而变化，使得在容器的任何横截面上发生特定的压降。 本发明可以在外部应用于容器，使得气体分配腿进入容器壁，或者完全插入容器内，或者甚至连接到内壁。 歧管和气体分配腿是连续的和非分隔的，以允许连续的气流通过气体注入口进入容器。 本发明还可以用作现有的体积处理容器的改进。
