_nteriors fi rm Johnson Controls has developed a new reaction I injection moulding(RIM)technique for instrument panels. The new process cuts costs and allows designers to apply even very complex designs to la rge su rfaces. 在汽车内饰的布局中,仪表盘的表面设计是一个非常重要的环 节。选择恰当的材质的内饰品不仅能带给驾乘者完美的手感,同时 The SU rfaee design of instrument panels plays an important role in treating the right atmosphere in a car S interior.The right textu re ensu res pleasant hapties;it also helps to achieve 也带来完美的视觉感受。 gh-quality visual impression. 然而,汽车内部的塑料零件生产十分复杂,存在多种不同的加 a hi工工艺与技术解决方案 因此,很难实现一体化生产及成本控制。 Manufaetu rjnq interior plastic pa rts iS tomplex.however. re many different processes and teehnical solutions.As a 传统的反应注射成型技术需要使用两种原材料。聚亚安酯开始 There a t.it iS diffieuIt to integ rate processes and controI costs. 多以两种液体配剂的彤式存在,而大多数热熔塑胶为固体颗粒 这 resul两种液体原料分别是异氰酸盐和多元醇 它们被各自保存在两个独立的可控温送料槽内,送料槽中配备有搅 两种化学制剂进行放热化学反应,就可以在铸模内得到聚氮酯聚合物。 可能呈泡沫状也可能为固体,而且在柔韧性和硬度上可能存在很大 差异,密度也可能相差很大,具体地从O 2到1 6;5等。 Conventional reaction iniection moulding techniques involve the use of two material tomponents.The polyu rethanes sta rtoutin Delletform,Theliquid cornponents are anisoeyanate The two Iiquids a re held in sepa rate.temperatu re—eontrolled iquid cornponents.whereas most thermoplastics 拌设备 然后由送料槽进入混合室充分混合 再引入注塑模具中,使这 begin as two lyo1. 使用这种聚亚安酯RIM注模法,如果配料用量不同,制得的铸件 and a polfeed tanks equipped with agitators.These a re fed to a chamber where they a re mixed.They then flow into the mouId where the two ehemicals undergo an exothermie ehemicaI reaction.ThiS forms the polyu rethaRe polymer in the mould, 不过,江森自控公司简化了这一制造工艺,且仅需使用一种原 材料,那就是脂类聚亚安酯。该化合物通常在汽车油漆中作为配料 使用,以便提高车漆的色泽稳定度与防紫外线性能 这一材料的主要不足在于成本较高,不过因为仅需一种原材料 公司有关人士如此介绍道。 Depending on how the polyu rethane RIM system iS va ry from flexible to extremely rigid.Pa rt density ean va ry widely.too.with speciifc g ravities ranging from O.2 to 1.6. ated.the pa rts can be a foam or a solid.and they can 即聚亚安酯,所以可以明显加快“RIM AIpha”加工过程,江森自控 f0rmul新工艺能产生出具有柔软手感的装饰面 由于整个流程都在密 闭模具中进行,因此还可以对表面厚度加以控制。这对于生产汽车 的隐蔽式气囊舱门大有帮助 , Johnson Controls has Simpliled the process howeverf, Instead it uses onIY one material:aliPhatie polyu rethane,ThiS iS usuallv found in automotive paints where its colou r stability and its resistance to Ultra—violet liaht a re needed.
