But this is not enough, to reduce the damage that stationery causes to children. You must also master certain skills in order to minimize the damage caused by stationery. Below, Lepusheng Stationery will share with you several tips on using stationery:
Wind oil fine rubbing quickly removes correction fluid
In the process of using the correction fluid, it is inevitable that some liquid will be applied to the skin, and then you will find that the correction fluid for a while is difficult to be washed with water. What should I do at this time? A bottle of essential oil can help, just apply a little oil on the hand with the correction fluid and quickly wash it off.
What is going on here, it turns out that the solvent in the wind oil dissolves the correction fluid. The correction fluid is mainly composed of titanium dioxide, glue and solvent (ethyl acetate); the main components of the wind oil essence are drugs, perfumes and solvents (paraffin oil). Both the correction fluid and the solvent in the wind oil act to dissolve other substances.
Wash hands frequently to prevent lead poisoning
It is not difficult to find out that many pencils and rubber colors on the market are very bright. Some stationery is printed with various cartoon characters. Some stationery is made into candy. Most of these stationery products can not be found. . Le Pu Sheng stationery recommended, buy stationery should try to buy light stationery. Because most of the brightly colored products contain too much lead, because the body is not completely French, the reason for less metabolism, children absorb more lead than adults, so children at the age of six are more prone to lead poisoning. The best way to prevent lead poisoning is to choose the stationery produced by the regular manufacturer when purchasing stationery, check the label of the lead on the stationery and try to choose light stationery.

If lead poisoning is serious, you need to drive lead under the guidance of a doctor.
Eye protection may not be eye-protecting
With the concern for the health of students, some stationery has also increased the health care function, the most common of which is the eye protection that claims to protect the eyesight. In the stationery store, all kinds of eye protection are not only the same price, but the quality is not the same. Some papers are light yellow, and some papers are light green. However, some doctors pointed out that these so-called eye protections not only fail to protect the eyesight, but also add attention to fatigue and increase the possibility of suffering from myopia.
When reading and writing, if the color contrast of the content is larger, it seems less effortless, and the degree of visual fatigue is correspondingly lower. The maximum color contrast is “black and whiteâ€. Correspondingly, if the color of the book is light yellow or light green, the color contrast of the paper and the word will decrease, which will seem more laborious, and cause visual fatigue. If the student is suffering from color weakness and color blindness, writing with colored books may also increase the severity of the color weakness.
