| 1. | Liquid oxygen bleaches contain hydrogen peroxide , which supplies the oxidizing agent directly
是强力还原漂白剂，用作为染色的脱色较多。 |
| 2. | These results confirmed quantitatively that lignin oxidation is essential for the delignification during oxygen bleaching
定量地证明了在氧漂过程中木质素氧化是脱木质素反应的实质。 |
| 3. | Oxygen bleaches are available in both a dry and liquid form . all dry oxygen bleaches contain inorganic peroxygen compounds , such as sodium perborate tetrahydrate and sodium percarbonate
漂白后所产生的二氧化锰会是巧克力色，所以必须使用酸性亚硫酸钠或保险粉来去除这种二氧化锰。 |
| 4. | Probably the best advantage of an oxygen bleach is that you can get rid of stubborn dirt and organic stains without having to use toxic and hazardous materials like chlorine bleach
过氧碳酸钠是一种具有多用途的新型氧系漂白剂，具有漂白、杀菌、洗涤、水溶性好等特点，对环境无危害。 |
| 5. | Sodium hypochlorite and oxygen bleaches should not be used together . the benefits of both are lost when combined . color removers , considered reducing bleaches , are also products in the bleach category
漂粉因为含钙( ca ) ，所以不能与肥皂共同使用，因为如一起使用时，则会产生钙的肥皂沉淀，这就是在洗衣业不能被使用的原因。 |
| 6. | Unlike many products that are sold as environmentally friendly cleaners that are not that effective , oxygen bleaches really do work and for some stains even do a better job than traditional bleaches or cleaners
过氧碳酸钠为白色结晶粉末状或颗粒状固体，由于碳酸钠与过氧化氢以氢键联接，其在水中有很好的溶解度，并随温度的升高而上升。 |
| 7. | Total kmno4 consumptions by lignin in both pulp and effluent were measured and the difference of this value from the kmno4 consumption by lignin in original unbleached kraft pulp was used as the indication of the extent of oxidation that lignin in the pulp experienced during oxygen bleaching
该方法对溶出残馀木质素的氧化结果分析发现其呈明显3个阶段：第一段木质素氧化的当量电荷数约4 ~ 5 /木质素单元；木质素总氧化电荷数大约为9 /木质素单元。 |
