The role of fire door filling material



1, rock wool material



Rockwool originated in Hawaii. After the volcanic eruption of Hawaii Island, the residents of the island found a wisp of melted soft rock on the ground, which is the rockwool fiber originally recognized by human beings. The production process of rockwool actually simulates the natural process of the volcanic eruption of Hawaii. After melting at high temperature above 1450℃, the international advanced four-axis centrifuge is used to centrifuge fiber at high speed. At the same time, a certain amount of binder, dust-proof oil, and water-repellent agent are sprayed into the cotton collector, collected by the pendulum process, and solidified and cut after laying cotton by three-dimensional method, forming rock wool products with different specifications and uses.



2, perlite fire door core plate



Perlite fire door core plate This product is non-toxic, tasteless, non-combustible, non-corrosive steel plate, 1100℃ high temperature does not melt and does not deformation, the combustion performance reaches A level. The perlite fireproof board meets the requirements of the new standard for fire door filling materials.



(1), good fire performance, can better play the role of fire prevention, environmental protection materials all environmental protection products, no pollution, this product and glass fiber reinforced materials and inorganic binder composition.



(2), with non-combustible, non-explosive, water resistance, oil resistance, chemical corrosion resistance, non-toxic and good mechanical strength, the product can be sawing, drilling, planing and other mechanical processing. High fire resistance, in the simulated combustion test, the flame does not deform when the higher temperature reaches 800 degrees, and has good fire resistance and flame resistance.



(3), the product material is cheap, suitable for a variety of fireproof materials, perlite fireproof board is made of expanded perlite powder a
