Correction fluid, also known as correction fluid and correction fluid, is one of the common office stationery, mainly used to cover errors on paper. Before the invention of the correction fluid, whenever there is a discrepancy in an important document, the document has to be invalidated if it cannot be corrected. The introduction of correction fluids has greatly reduced this waste. Today, correction fluid is one of the stationery products that can be seen everywhere in the office.
With the development of the stationery industry, the types of correction fluids have gradually increased. Bottle-type, pen-type, and even modified belts, whether it is a traditional bottle-type correction fluid, or a pen-type correction fluid, and a double-headed correction fluid on the market. There is no exception to the presence of a small steel ball in the bottle. Then do you know the role of this small steel ball? Before using the correction fluid, people will habitually pick up the correction fluid in their hands and shake it gently. Why?
Originally, there are three solvents, trichloroethane, methylcyclohexane and cyclohexane, in the correction solution. If the correction solution is left unused for a long time, the solution is easily stratified. If it is not shaken, the transparent adhesive is squeezed out, but since the solution does not contain a released gas such as carbon dioxide, it does not alleviate the solidification of the correction fluid. Therefore, the effect of adding small steel balls is to mix the solvent and the adhesive of the correction fluid to prevent delamination from occurring. It can be said that the steel balls act as a uniform stirring.
In addition, since the correction fluid is easy to dry in the air, the shape of the correction fluid is sealed, the liquid is not exposed to the air, and the principle of the bead on the modified mouth is to provide a liquid activity outlet for the sealed space, as long as When using it, gently use the force to ooze the liquid smoothly. The principle is the same as that of a gel pen and a ballpoint pen.
