Preparation of Nano-ZnO Dispersive Liquid and its Characteristics Analysis by Ion Exchange Controlled Release Method
The 001×7 type cation exchange resins modified by zinc ion which acted as controlled release suppliers of ions composing crystal reacted with sodium hydroxide, saturated calcium hydroxide and ammonia solution respectively, and nano-ZnO dispersive liquid was preparaed. The result of ultraviolet analyse about the dispersive liquid showed that nano-ZnO dispersive liquid prepared by using saturated calcium hydroxide has higher nano-crystallization degree and better dispersity. The exploring results of temperature and reactive time showed that under 60°C and 16 hours conditions nano-ZnO dispersive liquid has better dispersity and can’t agglomeration and sedimentation.
