The night is quiet, and the pens and pencils in the pencil case are not sleepy.

The pen pushed the pencil aside hard, and the pencil said angrily, "Brother Pen, why did you push me hard?" The pen proudly said, "My role is greater than yours. I have done more things than you. People from all walks of life need our help every day. And you! Only students in the first and second grades of primary school will use you. "

The pencil said unconvinced, "Yes! Children in the first and second grades of primary school can't practice basic skills at all without our help. Where can I write well? "

The pen looked at the pencil and thought, "That makes sense. Move your body outward. He then proudly said, "We spend much longer time than you do, unlike when you use it, it's gone. It's really hard luck! "

The pencil said carefree, "We are not in pain at all. When people use us to draw vivid pictures, although we use them shorter and shorter, like candles until we run out, we get precious works of art, some of which can last forever! " "

The pen moved outside without saying a word, and the pencil felt a lot looser.

It is also deeper and quieter, and pens and pencils have also entered a sweet dream.

[Pen and ink] Pen and ink text:

Once upon a time, there were two kinds of stationery: pen and ink, pen and ink. They have only heard of each other, but they have never met.

Finally, one day, the opportunity came. A pupil named Xiaodong bought both pens and ink. After dinner, Xiaodong put pen and ink on the desk and went to bed. In the dead of night, a voice came: "Brother Mo, I've heard so much about you, and we finally meet by destiny today!" Ink heard the sound and looked around. No one, but where did the sound come from? Just as I was wondering, the voice rang again: "My name is Pan, and I am lying next to you." Mo Yan looked at the side, really lay a slender guy. So, they met. Later, the ink understood: I need to fill my pen's stomach, or the pen will be thirsty. Mo was very happy because the first lesson he learned was dedication.

Xiaodong is good at drawing, and especially likes to paint nature with pens, so ink and pens accompany him all day. With the passage of time, the knowledge of the pen is wider and wider day by day. Gradually, he began to be proud. On this day, Ink said, "Brother Pen-"Before Ink finished, Pen shouted, "Who is your brother? I have more knowledge than you, and you don't deserve to be my brother! ! "In fact, what Mo wants to say is:" Brother Pen, are you thirsty? Drink some water. " Unexpectedly, I was insulted. Since then, ink has been hiding from pens.

Finally one day, an accident happened. On this day, Xiaodong took his two good friends-pen and ink to sketch. Painting and painting, the pen is thirsty and can't spit out the color. Xiaodong scratched and scratched, and it hurt Miss Paper, but she still couldn't draw it. At this time, the pen remembered Mo, a good brother who had been silently dedicating himself. Remembering the arrogant words and deeds before, the pen lowered its head and said to the ink, "It's my fault. I shouldn't look down on you. Now I know that my life will be worthless without you! " Ink listened to a silly smile: "In fact, none of us can live without anyone, and we will be good brothers in the future!" " After that, the two good friends hugged each other tightly.

Today, thousands of years later, pen and ink still stick to their promises and will never be separated.

What is the difference between the ink of three gel pens and the ink of a pen?

I only know one thing. Gel pen is oily, pen ink is not oily, more likely to be carbon. Maybe I was wrong. You can refer to it Thank you.

The History and Story of the Pen (the Evolution History of the Pen) I want to make a paper on the pen, which can cover all aspects, focusing on the change history of the pen shape.

pen

Wikipedia, a free online encyclopedia.

Pen According to the national standard of the Republic of China (CNS 6630), a pen refers to a pen tip welded to the tip of the pen tip (hereinafter referred to as the pen tip) and has a structure that can automatically transfer the ink stored in the pen container to the pen tip.

The types of pens are 1. Suction and 2. The type of ink cartridge depends on the structure of supplementary ink.

Modern pen is a writing tool that hides water-based ink in the pen holder, and continuously supplies ink to the pen tip through gravity and capillary action. Most pens can be replenished with ink. Common ink replenishment methods include replacing ink cartridge ink tube, piston ink delivery, ink absorber, pressure bag ink delivery, pull rod ink delivery or less common ink delivery methods such as submarine ink delivery. Some users also use syringes to inject ink into the ink tube of the ink cartridge for reuse.

history

It is generally believed that the modern pen was invented by Lewis E wortmann, who was originally an insurance salesman. Once when signing an important contract, the business failed because the pen he used leaked and stained the contract documents, which inspired wortmann to do a good job. But about this legend, according to the notes of the blog Pennote:

17 15 the structure and principle of mathematical instruments written by Nicolas Bion of France mentioned the use of pen covers to prevent ink from drying up.

The earliest ink storage pen was made by Muiz, the caliph of Egyptian Fatmid dynasty in 969.

The metal nib was recorded in about15th century. By the19th century, the pen tip should become a widely used tool. 1830-40 or so, pen tips using iridium began to appear.

The design of using Mo Dou to send ink to the tip of the pen also existed in the early19th century. From 1880 to 1883, there are still dozens of patent applications for pen tongues.

To sum up, none of the important parts of the pen was originally created or initiated by Wolman, so it is obviously biased to attribute the invention of the pen to wolman, but it is an indisputable fact to design an effective and simple pen tongue to stabilize the supply of ink and establish an important pen factory in the future.

In fact, the predecessor of the pen can be traced back to the feather pen in ancient Europe or even the earlier Egyptian reed pen. The history of the Egyptian reed pen can be traced back to the first dynasty in 3000 BC. All of them use the flexible surface on the outside of the pen holder to cut the pen tip suitable for writing. When writing, dip the tip of the pen and the front end of the pen into the ink to get a proper amount of ink to write on papyrus, parchment or paper.

The toughness and durability of both reed stems and bird feather tubes are always limited, so when metal technology is developed, some people try to make a pen tip with metal and install it on the pen holder to become a modern dip pen.

In addition to the pen tip, another problem worthy of improvement is the supply of ink. After all, it is not only troublesome to keep getting ink in the writing process, but also complicated to prepare another bottle of ink. So someone used a hollow pen to store ink, and through a small one, Mo Dao could supply the ink needed for writing from the back of the pen tip. The earliest historical record of fountain pen can be traced back to 10 century, and this earliest fountain pen has been used until 18 century. But only 1. Tough (metal) nib II. The ink storage mechanism and two other elements can be written, but this is not enough. 3. Smooth ink control (supply) mechanism is needed to ensure stable ink supply.

The first pen using the above three key inventions was made in AD 1850. But it was not until A.D. 1880 that mass production began. Waterman and Wirt in the United States were the major manufacturers at that time, with factories in new york, Bloomingdale and Philadelphia. Wortmann later swallowed Wilt. Become a big company specializing in pens. It didn't drop until 1920s.

At the beginning of the 20th century, American special pens were introduced into China and distributed in coastal cities. After that, Conklin, Eversharp, Pelikan, Sheaffer, Parker and other brands of pens poured in.

The structure of pen

A pen usually consists of a pen sleeve, a handle assembly, a pen holder and a water supply/ink storage mechanism. The handle assembly usually includes a nib and a tongue.

A pen cover is usually called a pen cover or a pen cap. Its main function is to protect the fragile pen tip from external impact, prevent ink from evaporating and drying up, and prevent water from polluting clothes and other objects. The pen must be covered when not in use, which is quite different from ballpoint pens and pencils.

For the convenience of carrying, a clip is usually attached to the pen holder to fix it in the pocket, and the design of the clip is also common in the ingenuity of designers. For example, the clip tightness of some pens can be adjusted, and the roller at the end of the clip is convenient for drawing, not to mention the arrow-shaped clip of Parker pen, which is almost synonymous with Parker pen.

In order to enhance air tightness and reduce ink volatilization, many modern pens use more elastic materials as the inner sleeve of the pen cover. In addition, many pens drill a small hole in the pen cover to balance the pressure difference, so as to avoid ink leakage caused by negative pressure similar to that generated by a piston when the pen is pulled out of the pen cover.

When a pen covers a pen sleeve, there are usually the following ways to fix the pen sleeve and the pen.

1, screw locking

2, elastic reed clamping

3, tenon claw

4. Magnetic assistance

pen point

The internal structure of a pen (LAMYsafari) Generally speaking, the meaning of the nib is very vague, which can be the tip that comes into contact with the paper when writing at the forefront of the pen, or it can include the whole nib, even the whole nib assembly including the strokes of the pen tongue. The names and functions of the components on the nib are as follows:

Iridium tip-the tip of modern fountain pen is welded with a small piece of platinum-iridium alloy, usually called iridium tip. A pen with an iridium tip is called an iridium pen in China, and the tip of a dip pen has no dots. Iridium dot can be said to be the most critical part of pen writing. The polishing size of the iridium dot determines the thickness of the pen width, ranging from fine to thick. Generally, the most common nib sizes are "B, M, F, EF", with B > M>F & gtEF from coarse to fine, and some pen factories have BB thicker than B and XF thinner than EF. The above nib sizes are only relative comparisons, and there is no consistent quantitative regulation in the industry. Therefore, it is possible that the F tip of A factory is thicker than the M tip of B factory. Japanese strokes are marked with Chinese characters too (thick), medium and thin. Usually, the nib of Japanese pens is thinner than that of European and American pens of the same specification.

The slit connecting the iridium dots is a rear slit, which is cut with a thin saw after the iridium is spot-welded to the pen tip, and its function is to provide a stable ink supply through the capillary action of the slit.

The end of the exhaust gap is usually connected with a circular hole.

According to the usual writing habits, Westerners usually use M-tip as the main pen and choose B-tip when signing. In Chinese writing, because of the complexity of strokes, it is generally possible to use M, F or thinner EF pen tips of European and American specifications or Chinese characters (M), fine characters (F) or extremely fine characters (EF) of Japanese specifications.

What does the story of five pens and ink tell us?

The story of pen and ink tells us that,

Only when you have ink in your stomach can you write a wonderful story!

Lying in the dirty garbage dump, the pen could not help crying sadly. She regretted taking the ink with her. No matter how beautiful it is, it can't be separated from the help of ink! )

What is the difference between six ink pens and water?

Ink includes pen water, which is a kind of ink.

Ink is a colloid containing pigments or dyes. Ink is used for writing or painting. The earliest inks were dyes made of metal, walnut shells or seeds, or inks made of marine animals such as fish and octopus. China ink is carbon ink. ? When people think of ink, they usually think of pen or brush ink first, but with the wide application of printing and dyeing and inkjet output technology, inkjet printing and printing ink are actually the most used.

Ink is divided into dye ink, pigment ink and thermal transfer ink.

1. Dye ink is completely soluble at the molecular level. This kind of ink is a complete compound solution, with low probability of blocking the ink head, easy to be absorbed by materials after inkjet printing, bright color and low cost.

2. Pigment ink is powder ink. Of course, this is just an image statement, which is not accurate enough. To be precise, it grinds solid pigments into very fine particles and dissolves them in special water solvents. It is a suspended solution or semi-solution, which has the same properties as the pigment of our printing and dyeing clothes. Contrary to the principle that dye ink penetrates into the medium to form color, it develops color by attaching color materials to the surface of the medium (such as copy paper or printing paper).

3. The image of thermal transfer printing is bright in color and rich in layers, and the effect can be comparable to that of printing. The difference is that the thermal transfer ink sublimes at high temperature, permeates the surface of the medium and condenses to form an image. Therefore, no adhesive film will be formed on the surface of the medium, the image will not fall off and crack, and it has strong light resistance and does not fade for a long time.

The principle of seven pens absorbing ink

When the pen is put into ink, the pressure on the skin is the same as that on the outside.

But the skin itself has an elastic deformation, that is, it has its own elasticity and can restore itself to its original appearance.

So the volume inside the skin began to increase, but the air did not increase, so the air density inside the skin decreased, and the air pressure was lower than the external air pressure.

Then, due to this air pressure difference, the external atmospheric pressure presses the ink into the skin.

Finally, the skin returned to its original appearance, and the gas inside was balanced with the atmospheric pressure outside, and this round of ink absorption was over.

Eight Questions about Pen and Ink

There is not much difference between a few dollars and dozens of dollars, at least there is no big difference. Bellick, Parker and other inks are actually the same thing, because the formula of ink has not changed much since it was invented.

As long as you don't buy carbon black ink, carbon is very sticky and blocks the pen. The bosses, heroes and ostriches I usually meet are all very good.

If you especially want to buy imported ink, buy a bottle of Parker blue-black, the color is very close to black, better than Parker pure black, pure black printing paper.

The advantage of 400 1 Belle Gold lies in its diverse colors. If you buy blue black or pure black, there is no need to buy his house.

Questions about pens and ink

Are you wearing a hat? If it is not covered, it means it is dry. Just soak it in water. Ink is unlikely to freeze.

If you want to recommend ink, Parker standard ink, the net price is about 20.

Who invented the earliest pen and ink?

Pen is a widely used writing tool. It was invented at the beginning of19th century. 1809, Britain issued the first batch of patent certificates about water storage pens, which marked the official birth of pens.

In the early water storage pens, ink could not flow freely. When the writer presses the piston, the ink begins to flow. After writing for a while, he has to press it again, otherwise the ink will not flow out. Of course it's inconvenient to write like this.

By 1884, wortmann, an employee of an American insurance company, invented a capillary ink supply method, which solved the above problems well. The end of this pen can be disassembled and ink can be injected with a small dropper.

The earliest pen that can absorb ink by itself appeared at the beginning of the 20th century, using a piston to absorb ink. When using a bladder in a pen, insert an iron sheet into the gap to squeeze the bladder to absorb ink. At 1952, there appeared a snooker pen with a tube inserted in the ink to absorb water. The commonly used capillary pen was not invented until 1956.

Blue ink was invented by Wedgwood in England in the early19th century.
