Do you know the common sense of the use of ballpoint pens?
1. The ballpoint pen is stronger and more durable than the general pen, but if it is used and stored improperly, it is often impossible to write. This is mainly because the dry and solid ink sticks around the steel ball and prevents the ink from flowing out. Ink is a kind of viscous oil, which is prepared with linseed oil, synthetic pine nut oil (mainly containing terpene alcohols), mineral oil (oil obtained by fractional distillation of petroleum and other minerals), hard glue and soot, etc. .
2. When using a ballpoint pen, do not write on paper with oil or wax, otherwise the oil and wax embedded in the copper bowl along the steel ball will affect the ink output and make it impossible to write. Avoid the impact and exposure of the pen. Always wear a good pen cap with gloves to prevent damage to the pen head, the deformation of the pen barrel and the oil leakage of the pen core and contaminate the body. If it is cold or not used for a long time. When the pen is not oily, you can soak the pen tip in warm water for a while and then swipe the pen tip on the paper to write.
3. The ballpoint pen has a big disadvantage: the handwriting it writes is very clear at first; but it cannot stand the test of time. Over time, the handwriting will slowly become blurred. This is because the ink for ballpoint pens is made with dye and castor oil. Oil is not the same as water. It is not easy to dry. Over time, the oil will slowly soak away from the paper, and the writing will become blurred. Therefore, the ballpoint pen can only be used as a common writing pen. If you want to preserve your handwriting for a long time, then you need to use a pen.
4. The ballpoint pen is on the ground. If the tip of the pen touches the ground at 90 degrees, the tip of the ballpoint pen will not be damaged. However, if the end of the ballpoint pen is bumped, the phenomenon of "oil leaking" will occur at the gap. In severe cases, the ball will fall off and appear. Difficulty writing, etc.
