Sandwich panel products are composed of a two-layer molded metal panel (or other material panel) and a polymer thermal insulation core that is directly foamed and matured in the middle of the panel. A board made of a high-strength surface material and a core material with a lighter bulk density and a smaller strength.
Its main advantages are: ① The specific strength of the plate is high. ② The core material is cheap and large, and the surface material is high and small, so the cost of producing this kind of product is low. ③ Reasonable selection and matching of surface and core material can effectively meet the pre-designed performance requirements of the board. For example, metal cladding is used to improve the fire and water resistance of the board, and decorative board or plastic sheet is used as the surface layer to improve its decorative effect.
characteristic 1. Light weight, the weight per square meter is less than 24kg, which can fully reduce the structural cost. 2, fast installation, light weight, plug, install and can be cut freely, determine the ease of installation, improve efficiency and save construction time. 3. Fireproof, the surface material and insulation material of the color steel composite core board are non-combustible or non-combustible materials, which can meet the requirements of fire protection regulations. 4. Fire-resistant, color-coated steel plate treated with special coating is guaranteed for 10-15 years. After that, anti-corrosive coating is sprayed every ten years. 5, beautiful, clear lines of the profiled steel plate up to dozens of colors, can meet the needs of any style of building 6. Low thermal conductivity and good thermal insulation effect. 7, environmental protection and noise prevention, composite board sound insulation strength of 40-50 decibels, is a very effective sound insulation material. 8, strong plasticity, the profiled steel plate can be cut at will, enough to meet the needs of special design.
Sandwich panels are used in large-scale industrial plants, warehouses, gyms, supermarkets, hospitals, cold storages, mobile houses, building floors, clean workshops, and places that require thermal insulation and fire protection.
