Production Procedure of polyurethane insulated sandwich roof panel polyurethane insulated sandwich roof panel
In terms of material proportioning and technical output of Zhongjie PU product, six-component mixed pouring technology (SIMENS) allowing on-line automatic operation which is art-of-the-date is adopted to take the lead in achieving six-component continuous foaming in China and finish proportioning process on line at one time. Besides, the formula can be adjusted in accordance with the environmental change to match with air-entrapping mixing unit to bring more well-distributed materials and finer foams for the purpose of producing high strength, energy saving, and environment friendly building panels.
De-coiling
We usually use the high quality pre-painted galvanized steel coil manufactured by Zhongjie itself, but other coils manufactured by Baosteel, Bluescope or any other brands that customers required are also available and acceptable.
Filming
The double metals are filmed in order to avoid scratch or other damage to the coating. The performances of the steel would deteriorate more quickly after the damage of the protection layer film.
Transfer
The top and bottom metal are transferred into the double-belt machine in this step. The shelves’ length should be above a certain length in order to keep the speed of the transfer coordinate with the rotating speed of double-belt machine.
Forming
The top and bottom metal are formed into different profiles, such as flat, wave, square wave, embossment, which can meet the aesthetic requirements of designers and owners. The profiles can also enhance the strength of the panel.
Preheat
The double metals are preheated by an air conditioner or heating tubes in order to control the speed of foaming and enhance the adhesion between the metal and foam.
Foaming
This step is the most complex and foremost step in the procedure of the production of polyurethane sandwich panel. Several chemical materials are mixed and sprayed onto the surface of the bottom metal.
Double-belt molding
The polyurethane foam is transferred into the double-belt machine continuously to be molded.
Cutting
The panels are cut into certain lengths automatically according to customer’s needs.
Stacking
The finished panels are stacked automatically by machine.
Packing
The finished panels are packed stack by stack with a protection film.
