| 中文摘要: |
| 目的 研究有机试剂包裹粉体磷酸一铵的接触角和防潮效果之间的关系，探索利用接触角筛选粉体磷酸一铵包裹型防潮剂的可行性。方法 使用油酸、单硬脂酸甘油脂、十二胺、固体石蜡、硬脂酸和十六醇对磷酸一铵粉体进行包裹，采用Washburn动态法测量接触角，用吸湿速率间接表征防潮效果。结果 随着包裹后粉体接触角的增大，其吸湿速度会减小。结论 可以通过测试包裹后粉体接触角的大小来优选包裹剂，使粉体表面改性，提高了粉体的防潮效果。 |
| 英文摘要: |
| The work aims to explore the feasibility of screening the moisture-proof inclusion agent with mono-ammonium phosphate powder by contact angle, through the study on the relationship between the contact angle and the moisture-proof effect with mono-ammonium phosphate powder coated with the organic reagent. Oleic acid, glycerol monostearate, lauryl amine, paraffin wax, stearic acid and cetyl alcohol were used as the wrapping agent of mono-ammonium phosphate powder. Washburn dynamic method was used to measure the contact angle. The moisture-proof effect was indirectly characterized by the moisture absorption rate. It was found that the moisture absorption rate of the coated powder would be decreased with the increase in its contact angle. The wrapping agent can be preferably selected by testing the size of the contact angle of the coated powder to modify the powder surface and improve the moisture-proof effect of the powder. |
