Product Overview
Specially designed for the insulation layer foaming of cold room panels, cold storage walls, refrigerated and frozen warehouses.
This high-pressure PU machine is purpose-built for the insulation layer foaming of cold room panels, cold storage walls, refrigerated and frozen warehouses. The 2A2B two-component system with independent temperature control and circulation stirring ensures consistent material quality for rigid foam insulation. Large-flow pouring design (300–2000 g/s) is suitable for rapid foaming construction of large-area insulation layers in cold rooms. High-pressure mixing molding at 10–18 MPa produces a uniform rigid foam structure, delivering dual compliance of thermal insulation and load-bearing performance. Accurate two-component metering with ≤±0.3% dosing accuracy ensures high raw material utilization rate, reducing engineering construction cost. With stable operation, the machine is suitable for mass construction needs of cold storage projects. The equipment meets the core needs of high flame retardancy, low thermal conductivity, long-term thermal insulation, compression resistance and moisture resistance, adapting to large-scale production of cold storage building materials.
Operation Workflow
Raw Material Preparation
Prepare polyether polyol and isocyanate at the target mix ratio (100:100-130) for rigid foam insulation, with proper conditioning for uniform cell formation.
Tank Loading & Temperature Setting
Load polyol into Tank A and isocyanate into Tank B; the 2A2B temperature control maintains 20-45°C with circulation stirring for consistent material quality.
High-Pressure Precise Metering & Mixing
The PLC dosing system (≤±0.3%) dispenses precisely; high-pressure mixing (10-18 MPa, 8000-14000 r/min) produces uniform rigid foam, with large-flow pouring (300-2000 g/s).
Large-Flow Pouring & Insulation Layer Foaming
Pour rigid foam for cold room panels and walls; the uniform structure delivers high flame retardancy, low thermal conductivity, and long-term thermal insulation for large-scale projects.
