Traditional industrial oil cleaning agent on the human body what harm
Workshop often use oil cleaning agent, a colleague said that oil cleaning agent is very harmful to the human body, this is true?
Industrial cleaning agents are divided into: environmentally friendly and non-environmentally friendly cleaning agents. Environmental protection are mainly: water-based cleaning agent, hydrocarbon cleaning agent. Non-environmental protection are mainly: trichloroethylene, dichloromethane, white oil, bromopropane, water, kerosene and so on. Some of them are highly toxic. They are not only very destructive to the ozone layer, but also easy to get occupational diseases after long-term exposure. Now the country is banning them.

Traditional industrial oil cleaning agents are very harmful to the human body, and long-term exposure to cleaning lotions such as trichloroethylene, dichloromethane, and toluene is prone to occupational diseases or poisoning. As humans gradually more and more awareness of environmental health, the use of new environmentally friendly oil cleaning agent more and more, and gradually replace the traditional type of cleaning agent. The new oil cleaning agent should have the characteristics of low toxicity and environmental protection.
Traditional industrial oil cleaning agents commonly used gasoline, alcohol, toluene, xylene, dichloroethane, trichloroethane, tetrachloroethane and turpentine. Organic solvents have a strong solubility for grease, and a small amount of solvent can dissolve and remove a large amount of dirt. However, most organic solvents are volatile and flammable, even explosive. There are certain safety hazards in production, transportation and use; organic solvents usually have certain toxicity, and long-term contact with the human body will damage certain functions of human organs to a certain extent, especially the more toxic halogenated hydrocarbons, methanol, Ethyl ether and other solvents. And the cleaning cost is high, not suitable for large-scale use in industrial production. The organic solvent method is effective for grease and other organic dirt, but generally cannot clean inorganic acid, alkali and salt dirt, and is currently being replaced by other washing methods or used in conjunction with other washing methods.

Part of the traditional oil cleaning agent for personal hazards are:
1, trichloroethane: used for ultrasonic machine cleaning and manual cleaning, can also be used as a dry cleaning agent and metal surface degreasing agent. It is a colorless non-burning liquid with a chloroform-like odor. Poisonous! Inhalation of low doses can cause alcohol-like intoxication; high doses have anesthetic effects and can lead to death in severe cases.
2, toluene: colorless transparent liquid, similar to the aromatic smell of benzene. Health hazards: irritant to skin and mucous membrane, anesthetic effect on central nervous system. Acute poisoning: Inhalation of higher concentrations of the product in a short period of time can cause obvious irritation of the eyes and upper respiratory tract, conjunctival and pharyngeal congestion, dizziness, headache, nausea, vomiting, chest tightness, limb weakness, staggering gait, and confusion. Severe patients may have restlessness, convulsions, coma. Chronic poisoning: long-term exposure can occur neurasthenia syndrome, hepatomegaly, female workers, such as abnormal menstruation. Dry, chapped skin, dermatitis.
3, methanol: low toxicity to the human body, because methanol in the body's metabolism will be oxidized to formaldehyde and formic acid (formic acid) more toxic than methanol, so drinking alcohol containing methanol can lead to blindness, liver disease, and even death. If you drink more than 4 ml by mistake, you will have poisoning symptoms. If you drink more than 10 ml, you will be blind due to permanent damage to the optic nerve. 30 ml can lead to death.
  
The use of oil cleaning agent should pay attention to the following matters:
1, avoid contact with the eyes or skin, if there is careless should immediately rinse with plenty of water. If you still feel unwell, please go to the hospital immediately.
2. When using, please wear appropriate work clothes, gloves and glasses/mask.
The new water-based oil stain cleaning agent of RBS Chemical uses an aqueous solution equipped with surfactants and a variety of washing aids to clean oil stains. The aqueous solution of surfactant has the function of wetting, emulsifying, dispersing, penetrating, peeling and solubilizing, which can make a variety of oily dirt emulsified and stripped in the cleaning liquid to achieve the purpose of complete dissolution and removal. The water-based surfactant cleaning method is the simplest and safest cleaning method in the chemical cleaning method at present. It is not accompanied by intense chemical reactions, usually in cold or warm water, with non-volatile, non-corrosive to the wash and skin, low cost, easy to transport and save and other significant advantages, especially suitable for use in industrial washing. In recent years, it is replacing the traditional organic solvent method and alkaline washing method. Is gradually becoming a substitute for gasoline, kerosene, diesel and other organic cleaning agents.
