What is a ballpoint pen? Why is it called a ballpoint pen?

The difference between ballpoint pens and ballpoint pens is that they use different inks and pigments.

1, ballpoint pens are oily pigments, ballpoint pens and gel pens are water-based pigments, but in terms of writing structure, ballpoint pens, ballpoint pens and gel pens are all the same, and the pigments are driven by balls.

2. Ballpoint pen (English: Ball Pen or balus Pen), also known as ballpoint pen or ball-running pen, is a modern writing tool. It uses ball-running balls at the end of the pen to distribute "ink (usually ink)", so that writers don't have to dip in ink as often as using pens.

3. Its working principle is that under the dual action of atmospheric pressure and ink gravity, the ink flows from the oil pipe to the ball seat of the pen tip, and then the ink adheres to the ball. When writing, the ink attached to the ball is attached to the writing surface along with the rolling of the ball on the writing surface, forming handwriting, that is, the purpose of writing is achieved.

4. Ballpoint pens can be divided into oily and neutral: oily ballpoint pens and inks are characterized by high viscosity and strong water, but there are many oil stains; Neutral ballpoint pen ink has moderate viscosity, less oil stains and smooth writing, and has better water resistance and light resistance than oily ballpoint pen ink.
