ABS是注塑工艺的绝佳搭档,其中的苯乙烯结构在受热熔融时可以为材料带来较低的粘度,为注塑生产提供充足的流动性;丁二烯结构的存在会为材料带来良好的韧性和抗冲击性能,特别是在低温下,塑料也不会变的很脆;而丙烯腈中的氰基具有超强的吸电子能力,形成的高分子链段具有很强的极性,链段运动能力变差,表现在宏观性能上就是材料的超高硬度和良好的强度。 Why choose ABS? This is because ABS material properties just to meet the all the requirements of Lego building . ABS is an excellent partner in the injection molding process, in which the styrene structure in the heat melt can bring lower viscosity of the material for injection molding to provide adequate liquidity. 由这三种性能迥异的原料共聚而成的ABS,同时具备三者的优点,并且很难结晶,它在模具中冷却时不会产生太大的收缩,因此它的尺寸稳定性也很好,做出来的小零件可以保持尺寸高度一致,这一点对拼插玩具而言尤其重要。 While it has three advantages, and difficult to crystallize, it is cooled in the mold will not produce too much contraction, so its dimensional stability is also very good, made out of small parts can keep the same height, which is Pin inserted toys is particularly important. 明白了ABS的性质,它给人们带来的痛楚其实也就不难理解了。疼痛来自局部的压强,而造成巨大压强的因素无非有两点:其一是尖,其二是硬。在注塑过程中,尺寸稳定性好的ABS很好地继承了乐高模具清晰分明的棱角,因此它的边缘自然也比较“尖”。 Understand the natu
