Classification of handmade materials

1. Metal materials

Metal material refers to the luster, ductility, easy to conduct electricity, heat transfer and other properties of materials. Generally divided into two kinds of ferrous metal and non-ferrous metal. Ferrous metals include iron, chromium, manganese, etc. Among them, steel is the basic structural material, known as the "skeleton of industry".

Due to the progress of science and technology, the wide application of various new chemical materials and new non-metallic materials, the number of substitutes for iron and steel is increasing, and the demand for iron and steel is relatively declining. But so far, the dominant position of steel in the composition of industrial raw materials is difficult to replace.

2. Plastic materials

Plastic is monomer as raw material, through the addition of polymerization or condensation reaction polymerization of macromolecules (macromolecules), its anti-deformation ability is medium, between fiber and rubber, by synthetic resin and fillers, plasticizer, stabilizer, lubricant, color additive composition.

3. Cloth materials

Cloth is a commonly used material in decorative materials. Including chemical fiber carpet, non-woven wall cloth, known and fu bureau linen, nylon cloth, color tape, flannel and other fabrics. Cloth plays a significant role in decorative display, and is often the main force in the entire sales space. A large number of cloth for wall decoration, partition, and background processing, can also form a good display style of commercial space.

4. Clay materials

Clay is a sticky soil with few grains of sand, and it is not easy for water to pass through it so that it has good plasticity.

General clay is formed after the weathering of silicate minerals on the earth's surface, generally weathered in situ, larger particles and composition close to the original stone, known as the original clay or a clay. This kind of clay is mainly composed of silicon oxide and alumina. It is white in color and refractory. It is the main raw material for making porcelain clay.

5. Wool material

Wool usually refers to the yarn spun from wool, there are also different kinds of chemical fiber material spun yarn, such as: acrylic fiber, polyester polyester, Persians fiber, etc.

Wool is generally divided into knitting wool (wool for short) and knitting wool (knitting wool for short) two types, with the number of yarn, special number and use as the standard of differentiation.

Wool: the number of strands is more than three (including three), but the number of strands is more than six (including six) for wool

Knitted wool: knitted wool with two strands and less than six strands, or finished products with a single strand designed for three purposes of knitwear processing.
