Banana water, also known as Tianna water (thinner), mainly used as paint thinner, in the paint, adhesive production process also often use banana water as a solvent, the basic ratio is 15% n-butyl acetate, ethyl acetate 15%, n-butanol 10 ~ 15%, 10% ethanol, acetone 5 ~ 10%, benzene 20%, xylene 20%. It can be seen that today's banana water is no longer a common name for a single chemical, but a general reference to a mixture of organic solvents. Since the application of paints, coatings and adhesives in our daily life is very extensive, you may have had "close contact" with it without realizing it. According to different uses and needs, people can use different raw materials to change the formula and proportion of banana water. For example, considering that benzene volatilizes very quickly and is very toxic to human beings, people often replace it with toluene and xylene, which retains the original physical and chemical properties of banana water and reduces its toxicity at the same time. This should be the general trend to change the formula and proportion of banana water. Banana water is toxic. As an organic solvent, banana water can be absorbed into the human body through the respiratory tract, digestive tract and skin. The toxicity of banana water to humans can vary depending on the formulation and ratios. The acute toxicity of banana water is mostly low, and exposure to a certain concentration and dose may cause irritation to the eyes and mucous membranes, with symptoms such as tearing, coughing, sore throat, etc. In severe cases, acute chemical bronchitis, bronchopneumonia and/or pulmonary edema may occur. Most organic solvents can cause central nervous system damage, headache, dizziness and different degrees of consciousness. Inhalation at high concentrations can be accompanied by liver and kidney damage. The characteristics of the toxic effects of banana water on humans are related to the exposure dose. When the human body is exposed to banana water, an unusual and serious damage to an organ system occurs, and it is necessary to make a new assessment from the point of view of its formulation and rationing, to determine the cause of the disease, and to give timely and effective treatment.
