(2)植物:如蓝靛草是生产蓝色染料的原材料,红花中的色素则可制成红色颜料。
(3)动物:如贝类的珍珠光泽为某些高级珠宝增添了光彩。 2. 制作过程 (1)采集与提取:首先需要从相应的原料中提取所需的色素。 (2)加工:通过粉碎、过滤和精炼等工序将原料进行进一步处理。 (3)调配:按照需求对不同的颜色进行调配和混合。 二、合成颜料 与天然颜料不同,合成颜料是通过化学反应和工业过程制造的。它们在颜色选择上更加广泛,而且颜色更为稳定。 1. 制造原材料 合成颜料的主要原材料是化学物质,如无机盐、有机化合物等。这些原材料在特定的条件下进行化学反应,生成所需的颜料。 2. 制造过程 (1)反应制备:通过化学反应制备出目标颜色的基本物质。 (2)干燥和煅烧:对制得的物质进行干燥和煅烧,以增强其稳定性和颜色表现。 (3)研磨和混合:将干燥后的物质研磨成粉末,并与其他添加剂混合,以获得所需的颜色效果和性能。 三、总结与翻译 综上所述,天然颜料与合成颜料在材料来源和制作过程上存在显著差异。天然颜料主要从自然界的动植物或矿物中提取,而合成颜料则是通过化学反应和工业过程制造的。在制作过程中,两者都经历了复杂的加工和调配过程,以满足不同领域的需求。 Synthetic and Natural Pigments: Materials and Manufacturing Processes: Natural pigments are extracted from various sources in nature, such as minerals, plants, and animals, with a long history dating back to ancient civilizations. These pigments offer a rich selection of colors and often possess a unique artistic charm. On the other hand, synthetic pigments are manufactured through chemical reactions and industrial processes, providing a wider range of colors and greater color stability. The materials used in synthetic pigments are primarily chemical substances like inorganic salts and organic compounds. The manufacturing process involves reaction preparation, drying and calcination, as well as grinding and mixing to achieve the desired color effect and performance. In conclusion, both natural and synthetic pigments undergo complex processing and mixing procedures to meet the needs of various fields.
