Water-soluble cutting fluid diluted with a lot of water after use, proletarium fire smoke and fire risk, after processing degreasing cleaning is simpler, the disadvantage is that machine tools and workpieces are easy to rust. The oil-soluble cutting fluid has good lubrication and anti-rust effect, but it will produce serious oil mist in high-speed cutting and worsen environmental health. In order to adapt to various lubrication requirements and improve the performance of the cutting fluid, various additives are often added to the cutting fluid.
The harm of cutting fluid to human health mainly lies in the toxicity of its additives. For example, nitrite, chromate, chlorine compounds are toxic substances, and nitrite and alcohol amines are easy to react to form carcinogenic nitrosamines; Phenolol used as a fungicide is also highly toxic.
Direct contact between metal cutting fluid and the operator's skin: 80% of occupational diseases caused by cutting fluid are formed in this way. Water soluble cutting fluid and oil soluble cutting fluid on the skin harm is different.
It is generally believed that oil-soluble cutting fluids are prone to oil acne, folliculitis, keratosis and skin cancer. Among them, oil acne is the most common, which is caused by skin contact with oil that blocks skin pores, leading to inflammation and formation of pus bubbles. When metal debris, grinding wheel particles, oxide particles and rust particles contact with the skin to block the skin pores, causing a rash, will induce folliculitis. Skin cancer and keratosis are mainly caused by polycyclic aromatic hydrocarbons (PAH).
Water-soluble cutting fluid can easily lead to irritant dermatitis and allergic dermatitis. Irritant contact dermatitis is an inflammatory reaction caused by local toxic effects of epidermal cells. Atopic dermatitis is an inflammatory reaction caused by antigen stimulation in the skin, which is an important reason for eczema of workers who handle cutting fluid.
2. The operator ingest the smoke formed by the cutting fluid through the respiratory tract: the oil mist formed by the oil-soluble cutting fluid and the micro-droplets formed by the vaporization of the water-soluble cutting fluid stimulate the respiratory mucosa and cause inflammation, and the irritating smell of the smoke and the odor generated by the corruption of the cutting fluid will also cause harm to the respiratory tract.
The use of cutting fluid safety needs to attract sufficient attention
In the process of workshop processing, the application demand of cutting fluid products is more frequent. It should be noted that the application of such products must pay attention to basic safety issues, because the composition of the ingredients that require direct contact must be reasonably distinguished. You know, many cutting fluid components on the market contain a lot of chemicals that stimulate the skin, once long-term contact is easy to cause skin redness and other allergic conditions, and even the existence of some toxic substances is easy to lead to chronic poisoning.
Therefore, for many processing enterprises, the choice of such products must ensure sufficient safety and environmental protection, otherwise the risk is really not small once it has toxicity. For many employees, in the specific processing process also need to do the corresponding safety protection work.
According to the regulations, the enterprise must do a good job of environmental protection and wastewater treatment according to the relevant requirements, and provide a safe and healthy working environment for employees. Therefore, as an important content, the reasonable selection and use of cutting fluid specifications must also be emphasized. Different cutting fluid products because of different manufacturers, their characteristics and use requirements are also different, which needs to be carefully read before the specific operation.
