| 隔离墩钢模具是由高分子复合材料制成,没有任何回收价值。树脂复合材料井盖采用不饱和树脂、玻纤等材料及钢筋骨架经特殊生产工艺复合而成。树脂的成分也有天然与合成之分,下面下面详细简述两者之间的差别。隔离墩中树脂的天然与合成之分:树脂一般认为是植物组织的正常代谢产物或分泌物,常和挥发油并存于植物的分泌细胞,树脂道或导管中,尤其是多年生木本植物心材部位的导管中。由多种成分组成的混合物,通常为无定型固体,表面微有光泽,质硬而脆,少数为半固体。不溶于水,也不吸水膨胀,易溶于醇,乙醚,氯仿等大多数有机溶剂。加热软化,最后熔融,燃烧时有浓烟,并有特殊的香气或臭气。分为天然树脂和合成树脂两大类。树脂有天然树脂和合成树脂之分。天然树脂是指由自然界中动植物分泌物所得的无定形有机物质,如松香、琥珀、虫胶等。合成树脂是指由简单有机物经化学合成或某些天然产物经化学反应而得到的树脂产物。合成树脂是塑料的主要成分。 The steel die for isolation pier is made of polymer composite material without any recycling value. The resin composite well cover is made of unsaturated resin, glass fibre and steel skeleton by special production process. There are also natural and synthetic components of resins. The differences between them are described in detail below. Natural and synthetic components of resins in isolation piers: resins are generally considered as normal metabolites or secretions of plant tissues, and often coexist with volatile oils in secretory cells, resin ducts or ducts of plants, especially in the ducts of heartwood parts of perennial woody plants. A mixture of various components, usually amorphous solids, with a slightly glossy surface, hard and brittle, and a few semisolid. It is insoluble in water, water absorption and expansion, soluble in alcohol, ether, chloroform and most other organic solvents. Heating, softening, and finally melting. When burning, there is smoke, and there is a special aroma or odor. It can be divided into natural resins and synthetic resins. Resins are divided into natural resins and synthetic resins. Natural resins are amorphous organic substances, such as rosin, amber and shellac, derived from the secretions of animals and plants in nature. Synthetic resins are resin products obtained by chemical synthesis of simple organic substances or by chemical reaction of some natural products. Synthetic resin is the main component of plastics. 我国的隔离墩钢模具成成就令世界瞩目。国际市场方面,近年来,工业发达国家的人工费用增加,其正向发展中国家特别是东南亚国家转移。其国内以生产高、精模具为主,人工劳动投入量大的模具依靠进口解决。因此,中低档的隔离墩钢模具国际市场潜力十分巨大。只要国产模具的质量能够有提高,交货期能够保证,模具具出口的前景是十分乐观的。 The achievement of steel mould for isolation pier in China has attracted worldwide attention. In the international market, in recent years, the labor costs of industrialized developed countries have increased, and they are transferring to developing countries, especially to Southeast Asian countries. It mainly produces high and precise moulds in China, and the moulds with large labor input rely on imports to solve the problem. Therefore, the international market potential of middle and low-grade isolation pier steel mould is very huge. As long as the quality of domestic molds can be improved and delivery time can be guaranteed, the prospect of export of molds and tools is very optimistic. |
