亚克力抛光

抛光亚克力组件是一个非常流行的选择,工程师在考虑光学器件的设计。亚克力以其优异的透光性、透明度和无色性而闻名。不幸的是,亚克力不像聚碳酸酯、聚砜和ultem等其他材料那样容易抛光到光学表面。内表面如螺纹孔很难达到高清晰度。

亚克力抛光可以提供最好的透明度和透光率的所有透明塑料。在挤压和铸造形式,亚克力容易抛光。根据组件的配置,可以使用四种抛光技术中的任何一种;蒸汽抛光、抛光、火焰抛光和直接机械抛光。

蒸汽抛光利用溶剂蒸汽在丙烯酸塑料表面流动。这种方法有利于内部特征,但它对丙烯酸的影响是产生更多的半透明完成。通常情况下,机加工光洁度越高,蒸汽抛光的最终效果越好。零件清洁至关重要。我们很高兴为您的加工丙烯酸塑料零件进行蒸汽抛光;然而,为了达到最佳效果,加工和丙烯酸抛光都应该由康涅狄格塑料公司完成。雷竞技最新app

Buffing of acrylic produces a good finish. Buffing is mostly used on exterior surfaces in larger components. Buffing utilizes a spinning cotton wheel with cutting compound. Being a mechanical process, the wheel leaves microscopic scratches and can leave a haze or uneven clarity on acrylic.

Flame polishing utilizes a hot flame to flow a surface. Much like spray painting, finish quality depends on the operator’s skill level. Done properly, flame polishing can produce some of the clearest finishes.

直接机械塑料抛光利用专用工具直接从机床上产生抛光表面。这种方法虽然技术含量最高,但却能生产出近乎完美的复杂表面轮廓。

丙烯酸polishing requires special skill since acrylic is a stress sensitive material and is fairly brittle. It can surface stress crack or craze due to poor machining or stresses setup from polishing. For the most stable, stress-free component, always specify anannealingcycle after machining, otherwise stress cracking will occur in service.
