Common sense of using ballpoint pen

1. The pen is stronger and more durable than ordinary pens, but if it is improperly stored, it often cannot write, which is mainly because the dry ink adheres to the steel ball to prevent the ink from flowing out. The ink is a viscous oily substance, which is prepared by using flax oil, synthetic pine nut oil (mainly containing terpene alcohols), mineral oil (oily oil obtained by fractionating petroleum and other minerals), and hard gum added with fume, etc. .
2. When using a ballpoint pen, do not write on oily or waxy paper, otherwise oil or wax will be embedded in the copper bowl along the side of the steel ball, which will affect the ink production and cannot write. Also, avoid the impact and exposure of the pen. Keep the cap with gloves when you are in order to prevent damage to the nib, the deformation of the pen barrel, and the oil leakage from the pen core, which will cause contamination. If it is cold or left unused for a long time. When the pen does not produce oil, you can soak the nib in warm water for a while and then stroke the nib on the paper to write the character.
3. The ball-point pen has a big disadvantage: the handwriting it writes is very clear at first; but it can not stand the test of time. As time passes, the handwriting will gradually blur. This is because the ballpoint pen's ink 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 on the paper and the handwriting will become blurred. Therefore, the ball-point pen can only be used as a general writing pen. If you want to preserve the handwriting for a long time, you need a pen.
4. The ballpoint pen lands on the ground. If the tip of the pen touches the ground at 90 degrees, the ballpoint pen tip will not be damaged, but if the neck is injured, it will cause "oil-falling" in this gap. Difficulty writing, etc.
