前言 表壳材料是手表工业中用量最大的金属材料,表壳的用途,现已从单纯的防护作用向兼作装饰品转化,尤其是在国际市场剧烈竞争的今天,表壳的造型、色泽和外观,往往在很大程度上影响了手表的身价,在手表工业中享有很重要的地位。为此,手表制造商们在表壳材料的研制方面做了不少的工作,以期获得竞争能力。为了对国外表壳材料的发展状况有一个概貌的了解,利于国内生产和发展借鉴,我们对国外表壳材料专利文献进行了较全面的调查,共查阅了自二十年代末至八十年代初计六十年的化学文摘,共收集了361篇有关专利。
Foreword Case material is the largest amount of metal used in the watch industry, the use of the case has now been transformed from a simple protective effect to double as accessories, especially in the fierce competition in the international market today, the case shape, color and appearance , Often to a large extent affected the value of the watch in the watch industry enjoys a very important position. To this end, watch manufacturers in the development of case material has done a lot of work, in order to obtain competitiveness. In order to have an overview of the development of the foreign case materials and benefit from the domestic production and development of reference, we conducted a more comprehensive investigation of the foreign case material patent documents, a total of access from the late twenties to the early eighties Sixty years of chemical abstracts, a total of 361 patents collected.
