Study on bleaching of sandstone of different ages in the world indicates that the formation of bleached sandstone is relevant to organic fluid flows. 国内外不同时代砂岩漂白现象的研究表明,漂白砂岩形成均与有机流体的参与有一定联系。
Leaves of Acer buergerianum; Cinnamomum camphora and Camellia oleifera were used as materials in the test. Leafages of three plants were treated with H 2O 2 and NaClO as bleaching fluid, bleaching effect among which were compared. 以三角槭、油茶、樟树的叶片为材料,用过氧化氢(H2O2)及次氯酸钠(NaClO)作漂白液分别对三种叶材进行处理,观察比较其漂白效果。
In the bleaching process, the value of pH, the consumption of bleaching fluid and the mixing time have effects on the quality of the product. 在脱色过程中,pH值、脱色剂用量及混合时间对脱色的效果均有影响。
