查询词典 bleaching

Oxidative bleaching by oxidation of its own to make a strong oxidation of colored substances were destroyed, so as to achieve the purpose of bleaching; food mainly used to restore the bleaching agent, mostly belonging to sulfurous acid and its salts, they are generated through the reduction of the role of sulfur dioxide can fruits and vegetables fade, it is widely used in food products such as bleaching and preservation.

氧化漂白是通过其本身强烈的氧化作用使着色物质被氧化破坏，从而达到漂白的目的；食品中主要使用还原漂白剂，大都属于亚硫酸及其盐类，它们通过产生的二氧化硫的还原作用可使果蔬褪色，因此广泛应用于食品的漂白与保藏等。

Secondly, study on bleaching of sandstone based on field characteristics, petrography, geochemistry and compared with other sandstone related, combined with geological setting of gas seepage in the area, reveals that natural gas leakage is responsible for bleaching of the sandstone on top of Yan\'an formation. The bleaching resulted from interaction between the reductive fluid and the rock. At the same time the bleaching suggests that the northeast of basin has experienced large scale gas seepage.

在此基础上，通过漂白砂岩野外露头地质特征、岩石学、地球化学以及相关砂岩的对比研究，结合研究区天然气逸散的地质背景，揭示砂岩漂白现象为上古生界天然气逸散过程中，还原性流体与岩石作用的结果，同时也表明其指示了天然气的大规模逸散作用。

In order to achieve high whiteness bleaching, it is the key to combine various chlorine-free bleaching sequences reasonably and select suitable aid agents, activating agents and chelants for raising the efficiency of bleaching agents and improving the bleachability of pulp.

如何对各种无氯漂剂进行合理组合，以及选择合适的助剂、活化剂或螫合剂来提高漂剂的漂白效率和改善纸浆的可漂性，是实现TCF高自度漂白的关键。

Estimating calculation method of consistencycan be used to calculate bleach agent consistency in the saturation water of fiber cell wall.. The main cause of the reaction rate of displacement bleaching being faster than that of conventional bleaching is that the bleaching agent consistency in the saturation water of fiber cell wall, when bleach liquor mix with pulp by displacement way, is bigger than that of by conventional way.

浓度估算法可用于估算漂剂在纤维细胞壁饱和水分中的浓度，置换漂白比常规漂白反应速度快的主要原因在于漂液以置换方法与纸浆接触混合后纤维细胞壁饱和水分中漂剂的浓度比常规方法的高。
