The PIR sandwich panel production line is driving the development of building insulation materials towards high performance and low energy consumption, and its technological iteration will continue to meet the upgrading needs of fields such as cold chain logistics and industrial plants.
PIR (polyisocyanurate) sandwich panel is an upgraded product of polyurethane (PUR), which forms a stable six membered ring structure through isocyanate trimerization reaction and has the following advantages:
Fireproof performance: The flame retardant rating can reach B1 level, and the high temperature resistance can reach over 150 ℃, far superior to PUR's B2 level (flame retardant needs to be added).
Thermal insulation efficiency: The thermal conductivity is as low as 0.019 W/m · K (25 ℃), the closed cell rate exceeds 98%, and the thermal insulation performance is better.
Mechanical strength: The core material density is 45-55kg/m ³, with high bending strength, suitable for high load scenarios.
Environmental friendliness: Using low VOC catalysts to reduce environmental pollution during the production process.
The PIR sandwich panel production line adopts highly integrated and modular design, mainly including the following systems:
Raw material processing system
Multi component foaming technology: supports cyclopentane or 141B foaming media, can be configured with 2-9 component mixing, and precise control of PIR formula.
High pressure foaming machine: Ensure foaming uniformity and closed cell rate.
Automated Forming System
Double track laminating machine: Integrated heating and pressure control, adjustable sheet thickness.
Surface material processing module: compatible with various surface materials such as color steel plate, aluminum foil, non-woven fabric, etc., and enhances adhesion through corona treatment.
Energy saving and Environmental Protection Design
The energy consumption is only 40% of similar products, and it adopts a fully enclosed internal insulation structure, without the need for additional insulation rooms.
Intelligent control system
Central integrated control platform: realizes parameter linkage, fault self diagnosis, and remote monitoring, reducing manual intervention.
Servo lifting mechanism: designed without a hydraulic system to avoid oil leakage and achieve more precise thickness adjustment.
Through modular combination, a single production line can flexibly switch to produce the following products:
Building enclosure panels: roof/wall sandwich panels, cold storage panels, with optional core materials such as PIR, rock wool, or glass wool.
Special scenario board:
Polyurethane edge sealing rock wool board: combined with PIR sealing technology, solves the problem of rock wool water absorption.
Purification board: used in high cleanliness environments such as medical and electronic factories.
Enterprises need to choose configurations based on product requirements:
High fire prevention requirements: Prioritize PIR sandwich panel production line, paired with polyester polyol raw materials.
Multi functional requirement: Modular sandwich panel production line, supporting quick switching between PU/PIR/rock wool.
Energy saving goal: Focus on energy consumption indicators.
