Polyurethane Coldroom Panel Production Line Sandwich Panel Production Line

Short Description:

Product Detail

Product Tags


The polyurethane cold storage board production line can meet the various production needs of customers. The modular design concept of the whole line makes all our components compatible with the whole line and can be combined at will. The cold storage insulation board production line has high adaptability, and can be designed with various configurations according to customer needs, quickly meet customer needs, and the price system is flexible. The modular design of the main engine makes the production line run well, the quality is stable and reliable, the loss of parts is small, and the maintenance and maintenance loss is small.


Working Principle
The polyurethane foam raw material is sent to the mixing head by the metering pump of the pouring machine in a certain proportion and mixed, and then evenly poured on the bottom surface material of the sandwich panel, and sent to the lamination conveyor together with the upper surface material, and the upper and lower panels are pinned on the lamination conveyor. Foaming and solidifying and forming; the solidified sandwich panel is trimmed on both sides on the production line, and the middle is cut to a certain length by an automatic cutting machine as required.

The core material of  PU coldroom panel is a product of polyisocyanate and polyether type or polyester type polyol in a certain proportion of the reaction. The features of PU insulation board: good heat conductivity, great water absorption, good in temperature preservation performance, excellent compressive strength and tensile strength, not easy to deformation, it is widely used in maintaining the combination of cold storage structure.
