Problems solved by technology
Among them, the chemical method is currently the most mature and effective method. This method mainly achieves the purpose of killing and controlling microorganisms in the cutting fluid by adding fungicides. However, most of these fungicides are chemical reagents, and many of them are harmful. Stronger chemicals, such as phenols, bromine, chlorine, amines and boron compounds, these fungicides containing toxic chemical components will cause different degrees of harm to the human body and the environment during use and subsequent processing

Embodiment Construction
[0025] The technical solutions and technical effects of the present invention will be further described below in conjunction with specific embodiments.
[0026] Prepare component A, obtain 8 kinds of component A with different composition proportions by adjusting the volume ratio of ethanol, n-butanol and 2,3-butanediol during preparation, as component A of 8 embodiment samples respectively, such as Table 1 shows.

[0030] Component B is dry yeast powder or live yeast liquid. When directly adding dry yeast powder to water-based cutting fluid, in order to increase the activity of yeast and better control the added yeast biomass, first resuspend the dry yeast powder with a small amount of sterile water, quickly recover in a 37°C water bath, and then measure Bacterial OD value, according to the OD value to determine the amount of addition. In addition, in orde...

The invention provides a water-based cutting fluid deodorant based on a biological method. The deodorant includes component A and component B. Component A is composed of one or more of ethanol, butanol and 2,3-butanediol mixed in any proportion; component B is dry yeast powder or active yeast bacteria liquid. The invention also provides a method for using the deodorant. The water-based cutting fluid deodorant and its use method provided by the present invention can effectively inhibit the reproduction of spoilage bacteria (especially anaerobic and facultative anaerobic bacteria) in water-based cutting fluid through biological antibacterial means, thereby significantly delaying the deterioration of the cutting fluid. Putrefaction process, so that the odor is significantly reduced or eliminated. In addition, the technical solution of the present invention adopts a biological antibacterial method, which has the advantages of mildness, environmental protection, and no energy input compared with the currently commonly used chemical and mechanical methods.
Description
Technical field: [0001] The invention relates to the field of cutting fluids, in particular to a water-based cutting fluid deodorant. Background technique: [0002] Water-based cutting fluid is an industrial liquid used to cool and lubricate cutting tools and workpieces during metal cutting, cutting, grinding, etc. It is usually composed of cooling medium, lubricating additives, surfactants, anti-rust composition etc. [0003] Water-based cutting fluid is prone to denaturation, deterioration, corruption and odor during processing, resulting in a short service life, especially in summer when the temperature is high, it may become corrupt and odorous within 2 to 3 days. This is because the emulsified cutting fluid contains mineral oil, fatty acid soap, amine, sulfonate and water, which are very easy to breed microorganisms and cause liquid corruption. Studies have shown that the microbial populations in water-based cutting fluids are mainly bacteria and fungi, and the bacter...
