1, the pen is more durable than the general pen, but if the use of improper storage, often can not write words, which is mainly due to dry ink bonding in the steel ball around the obstruction of ink outflow.
Ink is a kind of viscous oil, is made of flax, the synthesis of pine oil (the main containing terpene alcohol), mineral oil (distillation of petroleum and other minerals obtained by the oil), hard glue added to the oil fume and so on.
2, in the use of ballpoint pen, do not write on the oil, wax paper, otherwise oil, wax embedded in the edge of the copper bowl inside the ink and can not write words, but also to avoid the impact of the pen, exposure, when not used to set up a good pen cap, in order to prevent bad pens, pen variants and refill oil leakage and pollution objects. In case of cold or long unused.
When the pen is not out of oil, you can put the pen into warm water soaked for a moment before scratching the pen tip on the paper, you can write the word.
3, Ballpoint pen has a big drawback: the handwriting it writes is very clear at first, but it can not stand the test of time, a long time, the handwriting will slowly blur up. This is because the ink of the ballpoint pen is made of dyes and castor oil. Oil is not the same as water, it is not easy to dry, long days, the oil will slowly soak on the paper, the handwriting will become blurred. Therefore, the ballpoint pen can only be used as a common writing pen. If you want to save the handwriting for a long time, you need to use a pen.
