Is the toxicity of the correction fluid really strong?
At present, the main components of common correction fluids are trichloroethane, methylcyclohexane and cyclohexane. The toxicity of the toxicity is proportional to the concentration. The correction fluid contains chemicals such as lead, benzene, and hydrazine that are harmful to the human body. Long-term exposure is harmful. However, it should be noted that "long-term exposure has a certain impact on the body" does not mean that such things are placed in front of the eyes and then have an impact on people, but need long-term close contact. For example, a worker who works in a workshop with toluene as a lotion for a long time is exposed to 8 hours a day. Generally, there will be occupational diseases in three years. If this concentration is used, even if the correction solution is 100% methylcyclohexane, once. In three minutes, you have to use about 90,000 times before you get an occupational disease of toluene poisoning. That is to say, if you apply it 10 times a day, you can apply it for about 24 years. This is calculated on the basis that the correction fluid is a high concentration of toluene volatilization, and a few milliliters of the correction fluid, the volatile concentration is estimated to be not poisoned for a lifetime. Online on the correction fluid is toxic, three minutes of poisoning the mouse's network heat transmission video, in fact, this experimental design is unscientific, there are many problems. However, another component of the correction fluid, cyclohexane, has a mild irritant effect on the eyes and upper respiratory tract.
Is the correction tape safer than the correction fluid?
The main components of the correction tape are similar to the correction fluid, mainly including titanium dioxide, resin, and polystyrene. These three are not very toxic. Among them, titanium dioxide is a widely used substance in the chemical field because it is used in many cosmetics because of its low toxicity. Polystyrene has gradually been left out and abandoned in the chemical field. On the one hand, it has many alternatives, and on the other hand, it cannot be naturally degraded in the natural environment, causing certain harm to the environment and ecology. However, there is no clear evidence that it is too harmful to directly contact the human body.
Compared to the correction fluid, the correction tape is relatively neat and hygienic, and it is not easy to soil the child's clothes. In fact, the impact of qualified correction fluids and correction tapes on children is very limited.
