Glass and steel sculpture sculpture types is very common in our daily life, its beautiful shape, material quality, durable, as excellent sculpture materials, and also widely used in other industries, glass steel, as the name suggests, is a combination of glass and steel, so it has the characteristics of what? What are the advantages and disadvantages?
The advantages of glass fiber reinforced plastic sculpture
Light, high strength, only 1.5~2.0, only carbon steel 1/4~1/5, but the tensile strength is close to, or even more than carbon steel, and the specific strength can be compared with advanced alloy steel.
Good corrosion resistance, good corrosion resistance, atmospheric, water and general concentration of acid, alkali, salt, as well as a variety of oils and solvents have better resistance.
Excellent workmanship can according to the product shape, technical requirements, and to use the number of flexible choice of molding process; process is simple, can be a molding, the economic effect is prominent, especially for complex shape, not easy forming a small number of products, technology and its superiority is more prominent.
The utility model has the advantages of good design, sufficient selection of materials to satisfy the performance of the product, flexible design of various structural products according to requirements, and requirements for the use of the product, so that the product has good integrity.
The defects of glass fiber reinforced plastic sculpture
1., aging phenomenon, aging phenomenon is a common defect of plastic, glass fiber reinforced plastic is no exception, in ultraviolet light, sand and wind, rain and snow, chemical media, mechanical stress, etc., easily lead to performance degradation.
2. the long-term temperature difference of general glass steel can be used for long time at high temperature, general polyester glass steel in 50 DEG C strength decreased significantly, generally only used in 100 DEG C; general epoxy glass steel is over 60 DEG C, the strength decreased significantly. But it is possible to choose the high temperature resistant resin to make the long working temperature at 200~300 centigrade possible.
3. modulus of elasticity is low, the modulus of elasticity of glass fiber reinforced plastics is two times larger than that of wood, but it is 10 times smaller than that of steel (E=2.1 * 106), so it is often difficult to deform in the product structure. It can be made of thin shell structure and sandwich structure, and can also be made up of high modulus fiber or reinforced rib.
