Any chemical can be potentially harmful to human health! Chemical substances contained in cutting fluids can enter the human body through contact with skin, breathing, accidental consumption, splashing into the eyes, etc.
Friends engaged in mechanical processing, the best way is to check the MSDS file of the product you are using! Any regular product will have such a document detailing the possible dangers of its product to users and the corresponding countermeasures.
Today’s machine tools all operate at high pressure and the cutting fluid produced is atomized without protection and can easily be inhaled into the lungs. Therefore, high-end machine tools are equipped with smoke recovery devices. If your machine tool is not installed, it will take 5 seconds to enter operation after opening the safety door.
The most typical example is that nitrite, a powerful carcinogen and cheap anti-rust additive, can be detected in the cutting fluid used by most domestic factories! Our country still has no corresponding laws and regulations prohibiting it!
The harm of mineral oil for the human body is certain. Developed countries no longer use emulsified oil containing more mineral oil.
Its content is approximately 35%. Synthetic cutting fluids do not contain mineral oil, but have poor lubricating properties. To solve this problem, a micro-emulsified cutting fluid appeared, containing about 17% mineral oil, which significantly reduces damage to the human body.
Some additives are harmful to the human body. Some additives, such as those containing sulfur and chlorine, are banned in developed countries. Therefore, it is recommended to use green and environmentally friendly cutting fluid. EU environmental protection standard goes through SGS inspection. The city of Shenzhen in my country has already made this request.
At the same time, the cutting fluid also seriously pollutes the environment, and the recycling cost of the cutting fluid is higher than its own purchase price. For your own physical and mental health, it is necessary to wait a certain amount of time before entering the security gate.
