Rock wool composite board it is mainly based on color steel plate as the surface, non combustible rock wool as the core material, two-component polyurethane glue as cement, continuous heating and pressure composite molding, fixed length synchronous cutting and sandwich panel. In particular, the rock wool sandwich panel mentioned today is a product introduced from abroad.
rock wool composite boardIt is mainly a sandwich panel with color steel plate as the surface layer, non-combustible rock wool as the core material, two-component polyurethane glue as cement, continuous heating and pressurizing composite molding, and fixed-length synchronous cutting. In particular, the rock wool sandwich panel mentioned today is a product introduced from abroad. It is a new board based on the wide application of a series of light building boards, such as single-layer metal pressure board, rock wool (glass wool) pressure board, polystyrene sandwich board, polyurethane sandwich board and so on. After long-term research and continuous improvement, rock wool composite board mainly absorbs the advantages of the above light building board, and combines the two through modern technology to give full play to the unique performance of rock wool core material. It has remarkable effects in fire prevention, heat insulation, sound absorption, sound insulation, so as to expand the application of sandwich panels to a wider field. Of course, it is different from ordinary rock wool board. Composite rock wool board is to increase the cement surface layer on the basis of rock wool board, effectively improve the progress of the project. Composite rock wool board is also called external wall insulation rock wool board.
Rock wool composite board is natural igneous rock as raw material, by high temperature melting, spraying centrifugal force and high pressure energy gas, phenolic resin cementation. Although rock wool board in the weight, thermal conductivity and compressive strength, water absorption performance than the physical and mechanical properties of eps and polyurethane foam is poor, but it should be noted that it is now at a temperature above 600 ℃, the use of non-combustible class a outstanding features, thus expanding the scope of use of sandwich panels, suitable for high fire rating of structural lightweight board. At the same time, it is said today that rock wool composite board has a significant reduction in noise transmission. After using rock wool sandwich board, the indoor sound caused by the impact of rain and hail on the building roof steel plate is also significantly weakened. Then mainly through the test, according to the ISO717/82 and UNI8270/7 standard, select the density of 100kg/m3 rock wool sandwich board as the core material, rock wool composite board sound insulation effect can reach RW = 29 ~ 30dB. Composite rock wool board raw material is a variety of natural rock. At the same time add special adhesive and dust oil, heating, curing, so that we use the rock wool board.
