| 护坡砖模具的塑料材质经常使用的是聚丙烯的材质和ABS的材质,丙烯聚合而制得的一种热塑性树脂,是一种半结晶性材料,它比PE要更坚硬并且有更高的熔点。聚丙烯(pp)具有很好的可塑性,可溶性和韧性。ABS树脂是微黄色固体,有一定的韧性,它抗酸、碱、盐的腐蚀能力比较强,也可在一定程度上耐受有机溶剂溶解。ABS树脂很好的成型性,加工出的产品表面光洁,易于染色和电镀。,ABS树脂的优点是抗冲性、隔音性、耐划痕性,耐热性更好。 Polypropylene and ABS are often used in the plastic material of slope protection brick moulds. A thermoplastic resin synthesized by propylene polymerization is a semi-crystalline material, which is harder and has higher melting point than PE. Polypropylene (pp) has good plasticity, solubility and toughness. wufangbu.07858.netxinban.07858.netlalijii.07858.netshiyanji.07858.netliuhuaji.07858.net liuhuajii.07858.netABS resin is a yellowish solid with certain toughness. It has strong corrosion resistance to acid, alkali and salt, and can also tolerate dissolution of organic solvents to a certain extent. ABS resin has good formability, the surface of processed products is smooth, easy to dye and electroplating. ABS resin has the advantages of impact resistance, sound insulation, scratch resistance and better heat resistance. 护坡砖模具选用塑料模具生产,具有可拆卸性。模具的材质是与之紧密相连的,材料决定着模具的外观和质量。零件产量大、外形尺寸稳定的模具要采用高性能的材料制造,这类模具材料还能进行低真空表面强化处理,让模具的耐用度提高到新的水平。由于模具形状复杂,精度要求高,生产周期较长,模具加工成本较高,因此采用高性能的材料也是必要的。 The moulds of slope protection bricks are manufactured by plastic moulds, which are demountable. The material quality of the die is closely related to it. The material determines the appearance and quality of the die. Dies with large output and stable shape and size should be made of high-performance materials, which can also be strengthened by low vacuum surface treatment, so that the durability of the die can be improved to a new level. Because of the complex shape, high precision requirement, long production cycle and high processing cost of the die, it is necessary to use high-performance materials. 护坡砖模具工艺的安排尤为重要,合理的工艺安排能加快生产周期,缩短加工时间,有效节省成本。而且更重要的是精确合理的加工能够保证模具在生产过程的稳定和延长寿命。加工出错有的会导致模具烧焊,无论焊的多好,对模具来说都是一种损失;另外加工不好还有可能影响模具动作,降低模具寿命,导致模具在生产过程中出现拉裂甚至折断。 The arrangement of moulding technology for slope protection brick is particularly important. Reasonable process arrangement can accelerate production cycle, shorten processing time and save cost effectively. Moreover, more importantly, accurate and reasonable processing can ensure the stability and prolong the life of the die in the production process. Some faults in processing will lead to die welding, no matter how good the welding is, it is a kind of loss for the die; in addition, poor processing may also affect the die action, reduce the life of the die, leading to die cracking or even fracture in the production process. |
