对不起,晚到了。
百年灵用的是两面防眩蓝宝石镜面,robinlin 你提到的防磨擦问题,其实不用太担心。
因为BREITLING的水晶表镜采用一种防刮花的蓝宝石水晶玻璃。这种人造宝石的硬度仅次于钻石,(大部份品牌都是人造的),合成过程需要非常复杂的工艺和生产技术
经过多道工序,所有百年灵的蓝宝石水晶表镜两面均都经过双面防眩处理。
简单介绍一下他的制作过程(转自www.timezone.com (BREITLING FORUM)............
1. To make a sapphire crystal, the basic material used is a salt cleansed from any foreign body (ammoniacal alum). Calcinating this salt at 1200°C results in its decomposition into alumina (or aluminum oxide).
蓝宝石水晶玻璃的主要原料是一种经过洗涤后除去了所有异物的盐(氨明矾)。在摄氏1,200度下对其进行煅烧,从中分解出铝氧粉(即氧化铝)。
2. Alumina is then extracted from the furnace and passed over vibrating sieves to obtain an extremely fine powder with a diameter of less than one micron.
将铝氧粉从煅烧炉中提取出来。通过振动筛,筛出直径不足1微米的超细粉末。
3.The flame of the blowpipe, heated to a temperature of 2050°C, transforms the alumina into stone with the addition of oxygen and hydrogen.
用吹氧管喷出的高达摄氏2,050度的火焰,将铝氧粉烧结成含氧和氢的人造石。
4.At the top of the blowpipe, a hammer striking the alumina reservoir causes it to drop regularly onto a small rod.
边喷火,边用铁锤敲打铝氧粉储槽,使铝氧粉熔浆有规律地滴落在一个小棒上。
5.It takes fifteen hours for the ”corundum” (crystallized alumina) to form on the rod, somewhat like a stalagmite.
15小时后,棒上形成石笋状的“金刚砂”(氧化铝晶体)。
6.The stones are then sorted according to their weight, shape and appearance, before being refired at a temperature of 1800°C to stabilize the material.
按重量、形状和外观对金刚砂进行筛选分类;然后在摄氏1,800度下将其重烧,以提高材质的稳定性。 |
