分散剂

For the strong activity of Nano-Si02, the conglobation will happen easily. It is modified and dispersed with KH-570 and the ultra dispersing agent by means of mechanical and ultrasonic dispersion.

针对nano-SiO_2在涂料中不易分散且分散稳定性差，易发生一次团聚的问题，加入硅烷偶联剂KH-570和超分散剂，采用机械分散为主、超声波分散为辅的方法，对其进行改性和分散。

The results indicate that the sedimentation behavior of coal particles of CWS belongs to differential sedimentation and there is a conglobation between coal particles in CWS preparation. Stability of CWS prepared with lignin series dispersants is better than that prepared with naphthalene series, and the height and mean sedimentation rate of clarifying zone is about 68% of that of FDN when the dosage of additives is 1.0%.

结果表明，水煤浆中煤粒沉降行为为差异沉降，在水煤浆制备过程中，煤颗粒之间会发生团聚，掺1.0％GCL3S的水煤浆清液区高度及平均沉降速率仅为掺FDN的68％，木质素系分散剂制备的水煤浆稳定性能优于萘系。

Therefore, disease in the population has become more common recently. In view of this, submicron Negative-Ion powders and excited materials were adopted in this research. The submicron NI powders and excited material powders were treated with a dispersing agent and a ball mill used first, then it was blended evenly into water-borne polyurethane by a planetary deaerate stirring machine, and finally the water-borne PU composite films were coated onto release paper with a coating rod. The main purpose of this work is to manufacture a permanent composite film which is able to release NIs. Such film is expected to not only release amounts of NI but also absorb smells and effectively create fresh air.

有鉴於此，本研究采用次微米负离子粉体及激发材，先添加分散剂后利用球磨机做处理，再将次微米负离子粉体与激发材添加至水性聚氨基甲酸酯中，经由行星式脱泡搅拌机均匀混合，再以湿式涂布法，经由涂布棒涂布於离型纸上，脱膜后成复合薄膜，制备出於空气中释放负离子、吸收异味且清洁空气之永久型复合薄膜。
