FRP Sandwich composite panels 1, the product name: FRP Sandwich composite panels 2, product pictures: Introduction, product characteristics: glass fiber reinforced plastic composite board is a new kind of composite plate, the current international popular product USES the sandwich structure, outer layer is made of FRP glass steel plate skin, intermediate with high density polyurethane foam materials (sandwich layer can also according to customer need to select board, extruded board, honeycomb panel, etc.).Products are widely used in cold storage, a container, trailer car, trailer, temporary office, control box, etc. 4, product categories: composite materials 5, the main ingredients: FRP sheet, sandwich layer, embedded parts, etc 6, size: the thermal insulation layer thickness of 50-100mm, panel thickness ranging from 1 to 3 mm, refrigerated excellent heat preservation and heat insulation performance (polyurethane sandwich layer, for example, because of the different sandwich layer plate overall performance), can be made. According to user requirements of the specifications of the size. 7, the main advantages: 1) light weight: the weight of 30-40% lighter than traditional domestic product; 2) thermal insulation performance: glass fiber reinforced plastic panel thermal conductivity is about 0.23 W/m2. K, rigid polyurethane foam thermal conductivity coefficient of 0.018-0.028 W/m2. K, the total heat transfer coefficient K value can be less than 0.3 W/m2. K. 3) the surface performance: glass fiber reinforced plastic surface with a strong tensile strength, bending strength and impact toughness, not out of shape.For air, rain and general concentration of acid, alkali, salt and other medium has good chemical stability;High surface finish, anti-ultraviolet radiation, protect the light is good, don't change color, easy to clean, especially suitable for various car ads; 4) permeability performance: the double glass panels have impervious, excellent water resistance. 5) environmental performance: glass fiber reinforced plastic surface without volatile and corrosive substances, interlayer insulation plate filling cfc-free polyurethane foam board, green environmental protection; 6) easy maintainability: repair treatment has no obvious after repair, it is cars and steel, aluminum plate.
