过醋酸漂液的稳定性及稳定剂的选择

Stability of peracetic acid bleach liquors and selection of stabilizers

在一定pH条件下,温度升高和一些金属离子的存在加速了漂液中过醋酸的分解.选择8种稳定剂分别添加到过醋酸漂液中,测试结果表明稳定剂HSY,WX-540的稳定作用较好,漂白效果较理想.

The increase of temperature and the existence of some metal ions accelerated the peracetic acid decomposition in the bleach liquors under certain pH conditions. 8 stabilizers were selected to be added to the peracetic acid bleach liquors separately. The test results showed that the stabilizers HSY and WX-540 gave quite good stabilizing effects and quite ideal bleaching results.
