Polyurethane foaming system (domestic) PU polyurethane mixing and pouring device adopts a four-component mixing and pouring device: This device uses a high-pressure metering pump, a temperature control system and an automatic raw material feeding system. After the four-component raw materials are mixed, they reciprocate through the mixing head , poured on the steel plate. Performance and production technical indicators 1. Production PU sandwich panel size: thickness 40-250; width: 600-12002, unit pouring volume: 120-520g/s3, pouring head sweeping speed: 0-1800/s, online adjustable 4 , Number of pouring heads: a set of 5. Pouring head spray pressure range: 12-18Mpa, rated 15Mpa 6. Pouring head pressure adjustment: electric, remote control adjustment during sweeping 7. Flow system control of each component: flow automatic closed-loop control (also Manual) 8. Working nature of the unit: high-pressure continuous operation. Four-component high-pressure continuous foaming unit: In order to adapt to the stability of product quality for a long time and cope with various factors that affect product quality, it will be the most active and The two sensitive additives are separated and used as a monomer system to participate in the mixing. When abnormal foaming occurs, the amount of the sensitive component can be changed automatically or artificially at any time to control the quality of the product. For the pump system, it is increased to a four-group system. However, three of the systems will still be classified into one group of systems during the mixing process, and will still be classified into two systems when the high-pressure mixing heads are facing each other.
