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 according to the target mix ratio (100:100~130). Select the appropriate rigid foam formulation for cold storage insulation requirements.
Tank Loading & Temperature Setting
Load polyol into Tanks A1/A2 and isocyanate into Tanks B1/B2. The 2A2B independent temperature control system maintains 20–45°C with circulation stirring for uniform material consistency.
High-Pressure Precise Metering & Mixing
The PLC-controlled dosing system (accuracy ≤±0.3% full dynamic range) dispenses materials precisely. The mixing head operates at 8000–14000 r/min under 10–18 MPa pressure for high-pressure homogeneous blending.
Large-Flow Pouring & Insulation Layer Foaming
The mixed material is poured onto cold room panels or directly into cold storage wall molds. The large-flow rate (300–2000 g/s) supports rapid foaming construction of large-area insulation layers.
