How to achieve the oil-water balance in the cutting fluid of the emulsifying machine: the "oil degree balance" in the emulsifying cutting fluid. The cutting fluid prepared by the emulsifying homogenizing machine can be divided into three categories according to its formula structure characteristics: pure oil type, emulsifying type and fully synthetic type, which are respectively called cutting oil, emulsifying type cutting fluid and fully synthetic cutting fluid.
Emulsified cutting fluid can be regarded as emulsified pure oil product, and can be divided into emulsified oil (> 0.1um), microemulsion oil (< 0.1 μ m) Two kinds. With respect to cutting oil and fully synthetic cutting fluid with relatively simple system structure, the composition of emulsified cutting fluid is more complex, and the working fluid is O / W system, so the perspective of examining its formulation structure is more abundant.
How to achieve the oil-water balance in the cutting fluid of emulsion machine, there are three mixed systems containing oil, water and surfactant: emulsion, microemulsion, solubilized micelle and reverse micelle solution (swelling micelle solution). Most products belong to the first two types, and a few low oil products belong to the third type.
The water content of emulsified oil is generally less than 10%, and the oil content Zui is as high as 80%. The concentrated liquid is w / O type, and the request system can be stable only if it has a low HLB value. The appearance of emulsified oil diluent is usually milky white and not bright. The diameter of dispersed phase oil droplet is approximately in the range of 0.1-10um, and the wavelength of visible light is 0.4-0.8um. Therefore, the reflection of light in the emulsion is quite remarkable.
In addition, the lower limit (about 0.1um) of the size of the - General emulsion oil droplet is very close to the resolution limit (about 0.2um) of the ordinary microscope.
The microemulsion oil-water content can be as high as 30-60%, and the oil content is generally ≤ 30%. The concentrated liquid is O / W type, the diluent is mostly transparent liquid, and the oil droplet diameter is usually 0.05-0.1um- The water content of microemulsions with oil content of more than 50% can also be as low as 20%. The concentrated liquid is w / O type, and the diluent is blue white translucent liquid. It is a transition emulsion (fine emulsion) with oil droplet size between ordinary emulsion and microemulsion. The droplet size is 0.1 ~ 0.4um
