Building materials needed for the building scale model species
Building model of production material is very rich, in use must distinguish categories, different kinds of materials to take different mechanic technique, avoid caused by material properties is not adapt to the processing equipment of waste.Sand table model of the existing material classification can click on the several ways.
A, classified by chemical composition
Sand table model of materials can be divided into organic materials, inorganic materials, inorganic non-metallic materials, composite materials etc.Organic material such as cardboard, PVC board, special adhesive, and inorganic materials including all kinds of metal sheet, rod and tube.Inorganic non-metallic materials generally do not facilitate processing, such as: stone, ceramic, marl, etc., but the effect after forming more stocky.Composite materials using the most, but the cost is higher, such as: all kinds of plastic metal composite plate and entourage of component, may be in the production according to the material properties to change the model design.
Second, according to the finished product shape classification
Sand table model material can be divided into tile, plate, sheet, rod, tube, etc.
1, block size is larger, the ratio between the length, width and height within the three times, the commonly used material with foam (polystyrene), logs, etc.2 the section length, width, plank, than over 3:1, the thickness of 1.2 ~ 60 mm, 1.2 ~ 6 mm same as the ordinary paper sheet between regulation, more than 6 mm thick plate is commonly 2400 x1200mm (length x width).
3, sheet is thin, long, wide specification sheet with similar, just general under 1.2 mm thickness, including all kinds of paper, cardboard and transparent film printing.
4, rod and plate shape, length of section 10 times the diameter of the side or above, the central is solid.
5, tubing, hollow pipe wall thickness directly affect the toughness of the material.
Sand table model material is prefabricated into fixed form is helpful to improve the efficiency of production, but according to the need to choose, avoid far-fetched collocation and adverse effect.
Third, according to the material quality classification
Sand table model of materials can be divided into paper, wood, plastic, metal, composite, etc.Paper material processing convenience, low cost, including all kinds of printing paper and cardboard.Neat, wood form dimension sense is strong, can be processed into a variety of artifacts, including wood square, solid wood, wood core board, plywood, fiberboard, etc.Plastic material of adornment effect is best, colorful and varied, rich texture changes, including polyvinyl chloride (PVC), polyethylene (PE), polystyrene (PS) and poly (methyl methacrylate (PMMA), propylene green butadiene styrene copolymer (ABS),
etc.Material form cover timber, plate, sheet, rod, tube, etc, all is the indispensable material in sand table model.Metal materials, high hardness, smooth surface, can have very good supporting effect and decorative effect, including stainless steel plate/tube/pipe, all kinds of alloy plate, etc.
Different materials have different characteristics, according to the production needs proper collocation of sand table model, in addition, the proportion of various materials in the same sand table model can not completely equal, need to show the point.
