Introduction Metalworking fluids (MWFs) are complex mixtures of chemicals and are indispensable materials in industry.
Material and Methods Ozone was produced from air using a OZONFILT® OZVa type 2 ozone generator (Prominent), which is capable of producing up to 15 g/hour of O3.

The material of microelectrode is shot of and the splash metal scraps are formed, which are high temperature.
The material is become the condensate in a short time, and the hard martensite is formed at the surface of the microelectrode.
The great parameter can be selected at early stage and a large quantity material can be etched by one pulses discharge.

Noticeably, due to the higher density value of MgO, as it is a metallic oxide material compared to the density of the base fluid, the densities of the nanofluids are increased proportionally with concentration increment.

But the mixture of anti-seepage curtain is alkaline materials, the alkaline comes from the Ca(OH)2 generated by cement hydration reaction.
Because of acid corrosion for building materials, acid-fast cement and acid admixture are used to prevent the concrete curtain damaged by acid corrosion.
