Title:
液状の着色材をポリマー溶融物内に供給するための装置及び方法
Document Type and Number:
Japanese Patent JP2006502314
Kind Code:
A
Abstract:
An apparatus and a method for injecting a liquid dye into a polymer melt, which includes a metering pump with a metering inlet and a metering outlet. The metering inlet connects to a dye tank and the metering outlet connects to a polymer melt carrying component. To add the liquid dye to the polymer melt in the melt carrying component in a quantity that is as uniform and accurate as possible, the invention provides for connecting the metering inlet of the metering pump to a feed outlet of a feed pump, which connects with its feed inlet to the tank. With that, it is possible to generate a feed pressure at the metering inlet of the metering pump, which can be adapted to an injection pressure at the metering outlet of the metering pump.
