玻璃钢
玻璃钢(也称玻璃纤维增强塑料,国际公认的缩写符号为GFRP或FRP,属热固性塑料)是一种品种繁多,性能各异用途广泛的复合材料。它是由合成树脂和玻璃纤维及其他一些添加剂经复合工艺,制作而成的一种功能型的新型材料。其实,玻璃钢既非玻璃,也不是钢,它的基体是一种高分子有机树脂,用玻璃纤维或其他织物增强。因为它具有玻璃般的透明性或半透明性,具有钢铁般的高强度而得名。它的科学名称是玻璃纤维增强塑料。
FRP (also known as glass fiber reinforced plastics, the internationally recognized acronym is GFRP or FRP, belongs to thermosetting plastics). It is a composite material with various varieties and wide uses. It is a new type of functional material made from synthetic resin, glass fiber and other additives through composite process. In fact, FRP is neither glass nor steel, its matrix is a polymer organic resin, reinforced with glass fiber or other fabrics. Because it has glass - like transparency or translucency, it is famous for its high strength of steel. Its scientific name is glass fiber reinforced plastic.
玻璃钢雕塑模具材料主要有三类:
There are three main types of plastic mould materials for glass steel.
1、石膏材料做成的模具型腔,也叫碎模法。但石膏材料强度低、放置时间长时容易变形。
1, the mold cavity made of plaster material is also called the mold breaking method. But the gypsum material is low in strength and easy to deform when it is placed for a long time.
2、硅橡胶材料做成的模具型腔,也叫软模法。硅橡胶材料使用前为流体状态,流动性及填充性好。配制后经交联反应形成橡胶弹性体,可具有较大的弹性变形
2, silicon rubber material made of mold cavity, also called the soft mold method. The silicone rubber material is fluid state, fluidity and filling property before use. After preparation, the rubber elastomer is formed by cross linking reaction, which can have large elastic deformation.
3、用玻璃钢材料做成的模具型腔,也叫硬模法。也就是在玻璃钢模具上翻制玻璃钢雕塑,玻璃钢模具一般采用手糊成型方法,制作前应设计成型线路。
The mold cavity 3, glass steel material, also called die method. It is to make glass steel moulds to make glass steel sculpture. The mould of glass steel is generally used by hand paste forming method. The molding line should be designed before making the mould.
