The equipment is specially used for the production of exterior insulation board, color steel composite board, roof wall panel and other polyurethane composite board.

Graphite and calcium carbonate powder can be added in the raw material tank of the sheet special low-pressure foaming machine to increase the flame retardant effect. The foaming machine is one of the core equipment of the whole line, which is a new product independently developed by linxin company, specially used for polyurethane sheet production line. This machine has the characteristics of high repeat injection accuracy, even mixing, stable performance, simple operation and high production efficiency.

Technical parameters of sheet foam machine：

Head: high performance mixing device, material spit out accurate synchronization, mixing evenly; New sealing structure, reserve cold water circulation interface, ensure long time continuous production without blocking.

Metering pump, frequency conversion motor: low-speed high-precision metering pump, precise ratio, measurement accuracy error no more than ±0.5%, can pass through high viscosity, add powder materials; By frequency conversion motor with frequency conversion to adjust raw material flow, pressure, high precision, simple and quick proportional adjustment.

Touch screen: PLC and touch screen man-machine interface are used to control pouring, automatic cleaning and air flushing of the equipment, with stable performance and strong operability. When abnormal conditions occur, it will automatically discriminate, diagnose and alarm, and display abnormal factors.

Material tank: adopt three-layer material storage tank, stainless steel inner tank, sandwich type heating, outside insulation layer, adjustable temperature, safety and energy saving.
