Lu network reporter Wang Wenting
write wrong words, wrong questions, a correction solution, is a lot of people's time memory. Recently, a "modified liquid three minutes and half poisoned white mice" experimental video on the Internet hot, it caused a lot of people's surprise. The reporter has learned that the volatile solvents in the correction fluid contain poison, and experts do not recommend them. The market is hard to find. "Now few students have bought the correction solution." The owner of a stationery store near Shan Shi Xiao said, "usually you buy the correction tape, you can choose it, which is much better than the correction fluid." The reporter saw that there are five or six kinds of correction, and the price is between 4-7 yuan. "Now teachers do not allow students to use correction fluid. So we will not buy any more. Now there is only a small amount of stock. " A stationery shop owner of culture east road said, "only a few companies are still using financial personnel." Reporters learned that since 2008, the Ji'nan mid-term examination prohibits students from using correction fluid. If the examinee brings the correction fluid or the correction fluid into the examination room, even if it violates discipline, this rule will continue in the subsequent examination or the "code of examinees". Similarly, in the college entrance examination, correction fluid is also prohibited items, and the college entrance examination paper adopts online marking, which requires higher requirements for candidates. Experts: solvent containing poison does not recommend the use of "the main solvent of the correction liquid is generally three chloroethane, methyl cyclohexane, cyclohexane, the three types, its toxicity and the intensity of the toxicity is proportional to the concentration." Three chloroethane, also known as methyl chloroform, is a non flammable, nonflammable, odorless colorless liquid, which is toxic. High dose intake will have anesthetic effect and can lead to death. Methyl cyclohexane is an organic compound, micro poison, skin skin contact can cause red, dry and chapped skin contact, Shandong Light Industries College. The phenomenon of ulcers, cyclohexane aliquot, hexachrobenzene, is a colorless and irritating liquid. It is commonly used as solvent, chromatographic standard reference material and organic synthesis. The titanium dioxide and other components in the correction fluid are harmless. These three kinds of solvents are toxic. "The correction fluid is applied to the place to be modified by smearing, followed by the evaporation of organic solvents, and finally the white coating is attached to the paper. Toxicity is in a rapidly volatile organic solvent. " Professor Jiang said, as a teacher, it is not recommended that students should use correction fluid and modify products with a band. "This kind of product is not only a toxic problem, but it will also make students rely on it for a long time. It is easy to develop a bad habit of writing without thinking, and not to recommend students to use it.
