Why can a ballpoint pen write, why can t you use a ballpoint pen

Ballpoint pen writing principle: the ball can be rotated freely in the ball seat. The ink of the ballpoint pen flows to the ball ball through five grooves in the ball base, and when the pen is writing, the friction force drives the ball ball to rotate, so that the ink flowing to the ball ball is continuously transferred to the writing object.

Reasons for the oiliness of the ballpoint pen When the ballpoint pen is writing, a part of the ink is transferred from the ball to the writing object, please see that the ball is transferred to white, and the other part of the ink will be brought back to the ball seat with the ball ball rotation. A good nib is more thorough to bring the ink back to the tee with the rotation of the ball ball, and the ink is less stained on the outside of the tee head, which is cleaner. Poor pen head, most of the ink will be stained on the outside of the tee head, can not be brought back into the tee, that is, we call the oil phenomenon, when writing, it is easy to contaminate the writing.

If the ballpoint pen is fluent, there will be more ink, but the negative effect is that there is more ink, and if there is less ink, the disadvantage is not fluent. These two situations are a pair of contradictions, how to consider comprehensively, so that it can achieve the best effect, is the ballpoint pen manufacturing industry has been studying the subject. "White gold"The reason why the ballpoint pen is not only smooth writing, but also does not pollute the writing, and has a long service life, is well received by users, and the efforts in this regard cannot be underestimated.

Injuries caused by the tip of the ballpoint pen falling to the ground If the ballpoint pen touches the ground at 90 degrees, the tip of the ballpoint pen will not be damaged, but if the closing point is bruised (as shown in the picture), this will occur at this gap"Oily"phenomenon, in severe cases, the ball will also fall off, writing difficulties and other phenomena.

Correct Writing Angle for a Ballpoint Pen (55° 70°) When writing with a ballpoint pen, it is ideal to control the angle between 55° and 70°, when only the ball is in contact with the paper (the ball is hard......).Tungsten carbide or ceramic, very not easy to wear), the closing does not touch the writing, so as to ensure that the ballpoint pen in good writing condition to prolong the service life.

If the writing angle is too small and easy to wear the closing of the ball seat (the ball seat material is nickel, platinum, copper or stainless steel, which is much easier to wear than the ball ball), if it is in contact with the written object for a long time, even if the written object is paper, the ball seat can not withstand wear, which will cause the ball to fall off.

When writing, the pad paper is too thick, and the pen tip is in contact with the paper, which is easy to wear and de-bead, and it is recommended that the ball ball can not be copied; The ball beads should be copied at most 1, and it should not be more; The ball beads should be copied at most 3 to 4 sheets, not more, and it is best to write at 75 degrees when copying.

It contains colored refills, blue, black and other colors, the color of the paper and the refill water is contrasted, when the small beads of the nib rub against the paper, leaving a colored solution of the refill, so that you can see the color on the paper, which is the word you wrote.

The ballpoint pen relies on the freely rotating steel ball on the tip of the pen to bring out the ink in the barrel and write it onto the paper.

Because the color of your writing board is not the same as the color of your pen!

Question 1: Why can't official documents be filled in with ballpoint pens Ballpoint pen ink has a variety of volatile components, easy to use chemical solutions to eliminate nails, and it will become light and unrecognizable after being stored for a long time or after being damp. This is not the case with rollerballs and black fountain pens.

Question 2: Why can't I use a ballpoint pen to do questions during the exam? Why?

It's very simple. This is because there are some substances in the ballpoint pen that react easily with oxygen. Because the words will be blurry after a while.

Black pens are different. There's carbon in it. It's not just beautiful.

And it can be kept for a long time

Question 3: Why can't some documents be written with a ballpoint pen? To fill it out with a very formal black carbon pen.

On the one hand, it is out of respect.

On the other hand, black pens fade the slowest and have the least color loss under the same conditions.

Therefore, for important documents such as reimbursement, fill in with a black pen.

Avoid the inconvenience caused by the lack of clarity in the future.

Question 4: Why can't the accounting books be written with a ballpoint pen There is no such provision in the accounting book, but it stipulates how long the accounting information needs to be kept (such as 15 or 20 years), if the ballpoint pen is used to register the account books, after a few years, the handwriting registered with the ballpoint pen will be blurred, so we cannot use the ballpoint pen.

Question 5: Why can't legal documents be filled out with a ballpoint pen? As long as it is the true intention of the attacker, it is valid.

The reason why a ballpoint pen is not used is that the handwriting written by a ballpoint pen is easy to eliminate with chemical solutions, and it will become faint and illegible after being stored for a long time or after being exposed to moisture. This is not the case with rollerballs and black fountain pens.

Question 6: Why should I use a gel pen instead of a ballpoint pen for signing? The handwriting of a ballpoint pen is oily, and the oily substance will slowly volatilize in the air, so the handwriting will be blurred or even disappear after a long time, so the signature of important information cannot be done with a ballpoint pen.

Upstairs said that gel pen is easy to write and good-looking, and it has nothing to do with this problem!

Question 7: Why can't you use a ballpoint pen in the office The office uses a signature pen for everything. Ballpoint pens are not suitable for office use, especially for signing important documents, on the one hand, out of respect, and on the other hand, because black pens fade the slowest and have the least color loss under the same conditions.

Question 8: Why can't you use a ballpoint pen in the exam Now the exam requirements must be a carbon pen or a B2 pencil to paint the card, the original bluff is that the carbon pen oil can be stored for a long time, and the ballpoint pen oil can not meet the requirements of long-term storage, so it can't.

Question 9: Why can't you use a ballpoint pen for document signing 5 points Ballpoint pens use chemical raw materials, and the handwriting of the ballpoint pen can be completely erased on the paper through certain potions, and it will fade after a period of time. And the pen can be kept for a long time.

Question 10: Accounting bookkeeping is necessary to use a carbon pen, why can't a ballpoint pen Ballpoint pen is not conducive to preservation, a long time or stained with water traces to pretend, the word is gone, so it is generally necessary to archive or important written materials are not allowed to be written with a ballpoint pen, and the carbon pen is relatively stable.

1. Ballpoint pen.

Can't practice the words very well, because the pen head, suitable for everyone to use, when you use it will find that your words are written very well, but once you change the pen to use it will find that there is no good before, and use a ballpoint pen to write, your words will not have your own pen style, and it will look very unlevel 2, carbon pen (black), is used to write documents, because it looks more neat, and very clear, in terms of the effect of practicing words, no fountain pen is good, but much better than a ballpoint pen, Using a carbon pen to write will be very neat 3, the pen is the most suitable for practicing words, the words that are practiced are strong and powerful, and very good-looking, the recommended draft argues that you use a pen to practice words, so after the above comparison, you will find that the pen is used to practice words, if you are a student, it is recommended that you serve you or regret your homework with a pen, and the notes can be written with a carbon pen I hope it will be useful

A ballpoint pen is a common writing tool, but whether you can practice handwriting well depends on your writing habits and how you practice it.

The advantage of a ballpoint pen is that it writes smoothly and can be written on different materials of paper, such as smooth or rough surfaces. At the same time, the tip of the ballpoint pen is relatively hard, so it is easier to control the direction and force of the strokes. However, the disadvantage of the ballpoint rubber key pen is that the strokes are not full enough, the lines are not strong enough, and for some strokes that need to be full and powerful, you may need to use other types of pens.

Therefore, it is feasible to use a ballpoint pen to practice calligraphy, but if you want to practice calligraphy well, you also need to pay attention to the following points:

1.When practicing calligraphy, you need to pay attention to the basic skills of strokes, including the direction, strength, and structure of strokes, and you need to pay more attention to these details when using ballpoint pens.

2.The strokes of a ballpoint pen are relatively slippery, which can easily lead to incoherent strokes. Therefore, it is necessary to maintain a certain speed and strength when practicing calligraphy, so that the strokes are natural and coherent.

3.The ink of a ballpoint pen is relatively smooth and tends to stain the paper. Because of this, it is necessary to choose the right paper when practicing calligraphy to avoid ink penetrating into the back of the paper and affecting the writing effect.

In general, using a ballpoint pen to practice calligraphy can help you practice the basic skills of strokes, but you need to pay attention to the writing method and the choice of paper. At the same time, it is recommended to practice with other types of pens to better master the writing skills of different strokes.

No, it is possible to press the pengel pen

Press the tip of the pen to retract the gel pen that pops out the nib. There is no need to remove the cap when pressing the gel pen, and there is generally no cap.

A gel pen is a combination of a fountain pen and an oil-based ballpoint pen.

The viscosity of the writing medium is between water and oil, so it is smoother than ordinary oil-based ballpoint pens, and it is an upgraded product of oil-based ballpoint pens.

The principle of pressing the cap of the pen:

In fact, the top of the ballpoint pen has a gear-like structure, it has many chutes, each chute corresponds to a groove, there are two kinds of grooves, one is deeper, the other is shallow, and they are arranged at intervals.

When the ballpoint pen is pressed, the structure on the outside of the refill pops out of the previous groove, then slides along the chute into the adjacent groove and becomes jammed by the gear. If it is a deeper groove, the nib goes in, and if it is a shallower groove, the nib comes out, since these two grooves are arranged sequentially at intervals. So you can press the tip of the pen to come out and press the tip of the pen to go in.

When writing ballpoint pen characters, it mainly relies on the elasticity of the wrist and fingers, and uses the action of "point" to put down the pen, and the action of "press" to close the pen

1. Quick start and fast collection due to the strong sense of sliding and poor elasticity of the ballpoint pen nib, when writing, should pay attention to the premise of pressing, each pen should be light and easy to slide through, and then quickly close the pen.

The whole stroke must be done in one go, and it cannot be muddy and watery. If you emphasize the sense of "astringency" and pay attention to "weight" like using a fountain pen, it is easy to lose strength, be rigid and stiff, and have no aesthetic sense at all.

2. Pay attention to the strength of the ballpoint pen line, in addition to paying attention to its urgency, it is also necessary to pay attention to highlighting the changes in its weight, so that the strokes appear strong and round. If you press it, it will be coarse, and if you mention it, it will be fine. Because the tip of the ballpoint pen is a metal ball, no matter how to draw when writing, it is the trajectory of the center, so the press and the center of the pen can not copy the brushwork of the brush, but from the actual point of the ballpoint pen.

Ballpoint pens have a big drawback:

The handwriting it came out was clear at first; However, it cannot stand the test of time, and after a long time, the handwriting will slowly blur. This is because the ink of the ballpoint pen is made with dye and castor oil.

Unlike water, oil does not dry easily, and over time, the oil will slowly soak on the paper, and the handwriting will become blurry. Therefore, a ballpoint pen can only be used as a common writing pen. If you want to keep your handwriting for a long time, you need a pen.

The ballpoint pen is able to write because it uses a special design and technology to delay the bye.

The inside of the refill of a ballpoint pen usually contains a tiny ball made of metal, plastic, or ceramic, and is about between millimeters and 1 millimeter in size. As the refill slides against the paper, the ball rolls and turns, creating friction and abrasion by rubbing against the paper, causing the ink to seep out of the refill and leave marks on the paper.

In addition, the ink in the ballpoint pen is usually a high-viscosity oil-based ink, which has poor fluidity and can be kept on the surface of the ball and will not penetrate into the paper too easily, which also helps to maintain the clarity and readability of the handwriting.

Combined with the above design and technical factors, the ballpoint pen will be able to write smoothly on the paper

A ballpoint pen can write because it contains a small ball, usually a steel ball and a large or ceramic ball, which rolls under the lubrication of the ink, bringing the ink to the nib and leaving ink on the paper. The ink of a ballpoint pen is usually an ink or a water-based ink, which has good fluidity and viscosity and can flow smoothly from the vertical tip of the pen, leaving clear handwriting. In addition, the nib of a ballpoint pen is usually made of a harder material such as tungsten steel or stainless steel, which can create the right amount of friction on the paper to help the writer control the thickness and flow of the strokes.
