Micro-nano bubble water, preparation method thereof and mortar composition

[0042] A preparation method of micro-nano bubble water, comprising the following steps:

[0043] The preparation of micro-nano bubble water is realized by the micro-nano bubble aerator. The raw material water is tap water, the pH value of the tap water is 7.09, the air is used as the aeration source, the air intake volume of the aeration gas is adjusted to 8L / min, and the circulating aeration time is for 5min; stand for 1h to obtain micro-nano bubbled water.

[0044] At 25°C, dynamic light scattering was used to measure the particle size of the micro-nano bubbles with a scattering angle of 90°. The measured D10 of the micro-nano bubbles in the water was 158 nm (that is, the proportion of bubbles smaller than 158 nm in size accounted for 10%) , D50 is 354nm (that is, bubbles with a particle size smaller than 354nm account for 50%), and D90 is 768nm (that is, bubbles with a particle size smaller than 768nm account for 90%).
