Metering and blending synthetic resin mixes - in which microcapsules of materials are fed along screw barrel through perforated plates

摘要

Component materials are metered and mixed in a device with several different removeable sections and an end piece along a barrel connected to a housing, each section contg. a perforated plate, a detachable screw conveyor passes through the sections, a removable casing attaches the sections to the housing, and the arrangement has a drive. Suitable for filled thermosetting resin and hardener systems (e.g. epoxides) and especially using microcapsuled binders.
