What material does the car model make of?
Gypsum price economy, easy to use processing, used in ceramics, plastics, model making and so on. The plaster is exquisite in texture, easy to repair after surface decoration, easy to be preserved for a long time, and is suitable for making all kinds of required models, which is easy to display and display.
Oily sludge is an artificial material. Very soft, soft, hard after solidification. The clay has strong plasticity, and the viscosity and toughness are stronger than that of yellow mud (clay model). The utility model has the advantages of convenient use, convenient molding and trimming during molding, and is difficult to be dried and cracked after being formed, and can be used repeatedly. The oil sludge is higher in price and easy to carry, so it is more appropriate to make some small, special-shaped and curved shapes. Like other vehicles, boats with sludge is very convenient. Therefore, the use of brown sludge as the outermost layer of oily sludge is a wise choice. The main ingredients of oily sludge are talc powder 62%, Vaseline 30%, industrial wax 8%.
Clay material has a wide range of sources, convenient materials and low prices. After the "wash mud" process and the "refining process", the quality of the clay material is more delicate. Clay has a certain adhesion, plasticity is very strong, in the molding process can be modified repeatedly, arbitrary adjustment, repair, scrape, fill, make up more convenient. The utility model can be used repeatedly, and is an ideal molding material, but if the water in the clay is lost too much, the clay model can be easily contracted, cracked or even broken, which is not conducive to long-term preservation. In addition, there are not many methods to deal with the effect on the surface of clay model. When making clay model, it is necessary to use less sand content. It should be processed repeatedly before use, and it is convenient to use mud and cooked soil. Commonly used as a sculpture, roll and clay.
