Objective to establish a laboratorial test method of soaking the sample of hygienic protection beaded paint contacted with drinking water.
目的探讨与饮用水接触的卫生防护涂料浸泡实验的样品浸泡方法。
2
Methods: Soaking time, extraction time and the amount of water added were studied by the orthogonal test with the volatile oil's volume.
方法：采用正交实验法，以提油量为指标，对浸泡时间、提取时间、加水量三种因素进行了研究。
3
Waterproof performance: will be immersed in water ballast 100CM underwater, the water temperature to room temperature, 0.5 hours after the light soakingtest function.
