    • A dispensing nozzle is disclosed for use on a mixing head of the type employed in blending and dispensing polymerizable liquid components, especially in the manufacture of foamed plastic products. The nozzle is continuously self-cleaning without need for solvent flushing, making possible long periods of operation free of down-time for removal of accummulated, adherent polymerized material within the nozzle. The characterizing features of the nozzle are a frustoconical walled housing within which a spiro-helical finned rotor is spun to properly blend the separate liquid components prior to discharging the resulting mix into molds. The housing and rotor are configured to produce the necessary homogenization of the liquid components with minimum adverse effect on the physical cell configuration of the resulting polymerized foam, as well as minimizing internal buildup of polymerized material.
    • 公开了用于混合和分配可聚合液体组分的类型的混合头,特别是在制造泡沫塑料制品中的分配喷嘴。 喷嘴是连续自清洁的,不需要溶剂冲洗,从而可以长时间的运行,没有停机时间,用于去除喷嘴内积聚的粘附聚合材料。 喷嘴的特征特征是截头圆锥形壁壳体,在其中旋转螺旋翼片转子以在将所得混合物排放到模具之前将分离的液体组分适当地共混。 壳体和转子被配置为产生液体组分必需的均匀化,对所得聚合泡沫体的物理细胞构型具有最小的不利影响,以及最小化聚合材料的内部积聚。
