The structure of color steel rock wool sandwich panel solves the problem of single technology proposed under the background of existing color steel sandwich panel flame retardant materials, which leads to poor fire performance. Some sheet metal structures have low external fixation strength and low service life, which further increases the replacement cost.
The outer wall of the outer skin is equidistant provided with trapezoidal rib and triangular reinforcement structure, the inner hole of the trapezoidal ridge is provided with a moisture-proof layer, the moisture-proof layer is mixed with insect repellent powder, and the outer wall of the inner skin has equidistant columnar protrusions.
There are equidistant symmetrical trapezoidal ribs and triangular reinforcement structure on the outer wall of the plate skin, which is conducive to strengthening the use tension of the plate skin and effectively improving the use strength of the plate skin. The inner hole of the trapezoidal rib is provided with a moisture-proof layer, and the moisture-proof layer is mixed with insect repellent powder. The design of the moisture-proof layer is conducive to absorbing water, and the insect repellent powder can effectively play an anti insect effect.
The outer wall of the inner skin has equidistant columnar protuberances. The design of the cylindrical protuberances can improve the support strength of the inner skin and help to improve the service life.
