Polyurethane Fireproof Rock Wool Sandwich Panel Production Line

The polyurethane fireproof rock wool sandwich panel production line is a high-end equipment in the field of modern building enclosure system manufacturing, integrating multidisciplinary technologies such as materials science, mechanical automation, and intelligent control.

sandwich panel line

The production line of polyurethane fireproof rock wool sandwich panel mainly consists of seven core modules: automatic feeding system, polyurethane foaming molding system, rock wool pretreatment unit, composite pressing system, automatic cutting workstation, finished product packaging assembly line, and central intelligent control system.

Adopting high-pressure fluorine free polyurethane foaming technology to control the uniformity error of foaming density; Integrated infrared thermal imaging quality monitoring system to achieve real-time quality monitoring of each square meter of board during the production process; Capable of automatically optimizing process parameters based on environmental temperature and humidity to ensure product performance stability.

The production of polyurethane fireproof rock wool sandwich panels begins with a precise panel pretreatment stage. Galvanized steel sheet or aluminum magnesium manganese alloy sheet is unfolded on a CNC unwinding machine after degreasing and chemical conversion coating treatment, and is formed into the desired cross-sectional shape through high-precision rolling, with high forming accuracy.

The rock wool processing stage adopts a fully automatic longitudinal and transverse cutting system to cut the rock wool board to the design thickness, and at the same time, the surface of the rock wool is treated with technology to enhance its interface bonding with polyurethane.

The core advantage of the pu fireproof rock wool sandwich panel production line lies in its unique integration of fireproof technology. With the formula, the oxygen index of polyurethane foam can be increased to more than 32%, reaching the flame-retardant level.

PU fireproof rock wool sandwich panels have outstanding performance in five major fields due to their excellent performance: industrial plants, cold chain logistics, public buildings, clean room engineering, and prefabricated buildings..
