What is the general appearance of the revolving door?
metallic material. In all kinds of engineering materials, the most widely used metal materials. Iron and steel materials are widely used, in addition to because they have good mechanical properties, but also because the price is relatively cheap and easy to obtain, to meet a variety of performance and use requirements. As the alloy steel has excellent performance, it is often used in the manufacture of important parts. Stainless steel is used in automatic revolving door engineering. In non-ferrous metals, aluminum, copper and its alloys are the most widely used. Among them, the light weight, corrosion-resistant aluminum alloy in the automatic revolving door project in the most widely used.
Composites. The composite material is made of two or more materials with distinctly different physical and mechanical properties, and different materials can be used as the reinforcing phase and the basic phase of the material, respectively. The enhancement phase plays a role in improving the strength and stiffness of the matrix phase, and the matrix plays a role in enhancing the phase properties, thereby achieving excellent performance that is difficult to achieve for a single material.
Polymer Materials. Polymer materials usually include three types, namely plastic, rubber and synthetic fibers. High molecular material rich in raw materials, small density, and corrosion resistance. Plastic and rubber in the automatic revolving door project has a wide range of applications. Due to the very good elasticity in the proper temperature range, the rubber is used for the sealing strip in the automatic door project. The disadvantage of polymer materials is easy aging, poor flame retardancy and heat resistance.
