今天看到一篇 钢笔维修的网页 结尾提到 派克气压51笔帽不可抛光打磨 因为有剧DU 铍元素 未知是否真假?那是否所有老笔的包金或金灿灿的古董笔帽也有?查了一下说是铍是高致癌 是否呢?有大神来科谱一下咯!以下的链接 英文好的人可以看看:点击可到原网页Pen Repair Don'ts
原文是:Polishing a pen by hand gives better results, but takes a lot more time (which should give you some idea of how potent a material-remover the buffing wheel is – much more potent than is desirable for plated metal). If you must buff, use tape to mask off the imprints and trim first. There is NO justification for putting an all-metal pen or pen cap on a buffer. Aside from causing brassing, it will instantly reduce crisp engraving and engine-turning to a blurry shadow of what it once was. Don't use Brasso on pens. It is extremely harsh, and leaves a residue that promotes trim-damaging corrosion.
Note that correct buffing wheel speed is related to the hardness of the material being polished. Hard plastics such as Lucite acrylic are quite forgiving, but softer injection-molded plastics can catch on a too-fast wheel, tearing and burning deep scars into a pen's surface.On very soft plastics such as that used for the Parker VS, machine-polishing should not even be attempted. Finally, a warning about beryllium bronze, a material used for Parker clips from the Aerometric 51s on: beryllium is an extremely poisonous element, so never attempt to solder or weld broken clips that might contain it. Buffing intact clips on a wheel may also be risky. 最后这段的大概意思是 : 最后,是关于铍青铜的警告,一种用于派克钢笔笔夹上的,从气压上水的51开始:铍是一种剧毒元素,所以从来没有人尝试焊接或熔接可能含有铍的断裂的笔夹。在抛光轮上抛光完好的含铍的笔夹,也可能有危险。
相信很多人有过把金色的有点氧化的老笔帽动手擦亮或者用细沙纸抛亮的经历吧 这样的人应该不在少数吧?大家如何看待呢? |
