    • A method introduces additives into flowing or fluidised media. The spatially predetermined position of the additives in the flowing material, also called fluid bed, is obtained by controlling the pulsating injection, The introduction and exact dosing of additives, that is hardeners, dyes, gas producers and softener for instance, into a liquid plastic stream or metal stream (10) for instance, or the fluid bed of bulk material, such as powder, granules and pellets, is carried out by means of an injector. The invention is used in melting units, in hot channel systems, in tools, componens of tools and injection moulding machines, extruders, injection moulding, pelleting, burner and injection arrangements. The nozzle needle (3) of at least one nozzle (2), respectively, is variable and highly precisely moved for the introduction by means of a device and in such a way that additive (17) is dosed exactly in relation to the volume flow of the medium and that a pulsating stream (18, 36) is injected into the medium flowing past, by means of at least one well-aimed nozzle opening (4). The additives are dosed by means of a pressure that can be variably adjusted by pulse width and pulse frequency. The desired homogenous distribution is obtained by the penetrating injection jet (37) during compounding.
    • 一种方法将添加剂引入流动或流化的介质中。 添加剂在流动材料中的空间预定位置(也称为流化床)是通过控制脉动注射获得的。引入和精确计量添加剂,例如硬化剂,染料,气体生产者和软化剂,例如进入液体塑料 流或金属流(10)或散装材料的流化床(如粉末,颗粒和颗粒)通过注射器进行。 本发明用于熔融单元,在热通道系统中,在工具,工具和注塑机组件中,挤出机,注射成型,造粒,燃烧器和注射装置。 至少一个喷嘴(2)的喷嘴针(3)分别是可变的并且被高度精确地移动以通过装置引入,并且使得添加剂(17)相对于体积流量精确地定量 并且通过至少一个良好瞄准的喷嘴开口(4)将脉动流(18,36)注入流过的介质中。 添加剂通过可以通过脉冲宽度和脉冲频率可变地调节的压力给药。 通过在混合过程中的穿透注射射流(37)获得所需的均匀分布。
