What is handmade?
Classification of hand-made materials: 1, metal materials Metal materials refer to materials with luster, ductility and easy conduction and heat transfer. Generally divided into ferrous metals and non-ferrous metals. Ferrous metals include iron, chromium and manganese. Among them, steel is the basic structure material and is called "industrial skeleton". Due to the progress of science and technology and the wide application of various new chemical materials and non-metallic materials, there are more and more substitutes for steel, and the demand for steel is relatively reduced. But so far, the dominant position of steel in the composition of industrial raw materials is still difficult to replace. 2. Plastic materials Plastics are macromolecules polymerized from monomers through addition polymerization or polycondensation. Their deformation resistance is moderate, between fiber and rubber, and they are composed of synthetic resin, fillers, plasticizers, stabilizers, lubricants, pigments and other additives. 3. Cloth cloth is a commonly used material in decorative materials. Including chemical fiber carpet, non-woven fabric wall covering, linen, nylon cloth, colored adhesive tape, flannel and other fabrics. Cloth plays a considerable role in decoration and display, and is often the main force that can not be ignored in the whole sales space. A large number of fabrics are used for wall decoration, partition and background treatment, and can also form a good commercial space display style.
