据报道(日本《写真工业》1980,38,7,24～32),由于银的价格猛涨,严重影响照像感光材料的制造成本。用于感光材料的银量约1000吨(1978年度)占银的总销费量的一半。银的感光材料购买价格对应于购入金比率,从1978年的14%急增到1979年的32%。感光材料制造中银的节约以及从处理液中回收银的技术的提高乃是当务之急。文中还记述了银的生产,感光材料的种类与含银量,介绍银的节约与回收等等。
It is reported (Japan’s “Photo Industry” 1980,38,7,24 ~ 32), due to the soaring price of silver, seriously affecting the manufacturing cost of photographic photosensitive materials. Approximately 1,000 tons of silver (for fiscal year 1978) used in photographic materials account for half of the total sales of silver. The purchase price of silver for photographic materials corresponds to the purchase price ratio, rising sharply from 14% in 1978 to 32% in 1979. The saving of silver in photographic material manufacturing and the improvement of the technology of recovering silver from the processing liquid are imperative. The article also describes the production of silver, the type of photosensitive materials and silver content, introduce the silver savings and recycling and so on.
