What is the raw material of a fondpen? What is an oil based pen also called?

Yes dyes, film-formers, solvents, dispersants.

Brief introduction. A ballpoint pen (English: ballpen or ballpoint pen), also known as a ballpoint pen or ballpoint pen, is a modern writing instrument that uses a ball at the end of the barrel to distribute "ink (usually ink)" so that the writer does not need to dip the ink as often as a fountain pen.

Principle. Its working principle is that under the dual action of atmospheric pressure and the gravity of the ink, the ink flows from the oil tube to the ball seat of the pen head, and then the ink adheres to the ball. When writing, the ink adhered to the ball beads adheres to the writing surface with the rolling of the ball on the writing surface to form handwriting, that is, the purpose of writing is achieved.

History. 1. Inventors.

In the 1930s, the Hungarian journalist Byro invented the first ballpoint pen (ball point pen) A pen that uses a rolling ball as a nib to write on a handkerchief or on a wooden surface without having to be filled with ink, and the newly invented ballpoint pen costs as much as $10. Let's take a ballpoint pen to observe, we can see that the tip of the pen has a small steel ball with a diameter of about centimeters, which is made of an alloy of chromium and steel, which is very pressure-resistant and wear-resistant; This little ball sits in the nib of the pen, and when we take the pen and slide it across the paper, it rolls and brings the ink that is in the upper barrel to the paper. This small ball is the biggest feature of the ballpoint pen.

gel pen.

Oil-based pens are used as opposed to water-based pens and alcohol pens, and oil-based pens are often used to quickly express design ideas and design renderings. It is one of the most important drawing tools at present, with a single head and a double head of thickness, which can quickly express the effect. Oil-based pens are characterized by quick drying, water resistance, softness, and light fastness is quite good, and the color will not hurt the paper when stacked many times.

The advantages of oil-based pen are that the ink viscosity is large, the writing length is large, that is, more words can be written under the same ink output, and it is fast drying, water resistant, soft, and lightfastness is quite good, and the color will not hurt the paper if superimposed many times; The disadvantage is that the writing feel and writing quality are not good. The oil-based pen is one of the most important drawing tools at present, which can quickly express the effect.

Call it whatever you like, casual! You can call him little oil. or oil. Ballpoint pen?

The medium oil pen is the "neutralization" product of the neutral ballpoint pen and the oil-based ballpoint pen.

The viscosity of the ink is close to that of the gel pen, which is a low-viscosity oil-based ballpoint pen, so it maintains the writing fluency characteristics of the gel pen, and dries quickly after writing, without worrying about getting hands, but it excludes the shortcomings of the neutral ballpoint pen that it is easy to break the ink and may reverse the current, and avoids the shortcomings of the oil-based ballpoint pen due to the ink being too sticky and not smooth enough.

Identification of different types of pens:

1. Water-based pen:

The ink used in the water-based pen is pure water-based, and the paper has strong absorption of it. Water-based pens are generally used on the absorbent surface, even if applied on the non-absorbent surface, they can be erased, and there is generally no back mark when writing on paper. The advantage is that the writing feel and writing ***, the disadvantage is that the ink viscosity is small, the writing length is small, that is, the same amount of ink can write fewer words.

Water-based pens are more odorless than oil-based pens, the nib is not easy to dry, its handwriting is light-resistant but not water-resistant, and it will be rendered when it encounters water, and it is easy to break the water if you accidentally fall over. Water-based pens include: fountain pens, ordinary pens, gel pens, rollerball pens, rollerball pens, rollerball pens, highlighters, whiteboard markers, watercolor pens.

2. Oil-based pen:

The oil pen uses the ink to be oily, insoluble in water, not easy to fade and dissolve, the oil pen can be written on the absorbent and non-absorbent surface, and is not easy to be erased, written on white paper, there are obvious back marks on the back, often used in the occasion of the need to mark. The advantage is that the ink viscosity is large and the writing length is large, that is, more words can be written under the same ink output; The disadvantage is that the writing feel and writing quality are not good. Oil-based pens include:

Ballpoint pens, markers, paint pens, gel pens.

3. Gel pen:

The nature of the ink used in gel pens is between water-based pens and oil-based pens, and the storage time is longer than that of water-based pens, and it is not easy to melt when exposed to water, but the properties are not as stable as oil-based pens. When writing some documents that need to be saved, gel pens are often used.

Oil pens are compared to water-based pens and alcohol pens, the ink used is oil-based, insoluble in water, and not easy to fade and dissolve. Oil pens include ballpoint pens and do not include charcoal pens. The ink viscosity of the oil pen is large, and the writing length is large, that is, more words can be written under the same ink output, and it is fast-drying, water-resistant, soft, and lightfast, and the color will not hurt the paper if superimposed many times.

The disadvantage of oil pens is that the writing feel and writing quality are not good. Oil-based pens are available in single and double thicknesses, and are one of the most important drawing tools at present. The ink inside the carbon refill is mainly composed of graphite, which is one of the most stable substances in nature.

Therefore, writing with a charcoal pen will not cause the font to become blurry due to the storage time for too long.

Paraffin oil 1, play a sealing role, prevent the pen water from volatilizing and drying;

2. Use the principle of atmospheric pressure to prevent the pen water from flowing backwards.

The inks of ballpoint pens are specially made and are mainly made from a mixture of pigments, solvents and viscosities. Common colors are blue, black, and red. Ordinary ink is mostly used for general writing, and special ink is mostly used for archival writing.

The ink used for archival writing is generally marked on the refill, such as the domestic refill, which is marked with the word da.

The main ingredient is ink. The pigment of the ink is a dye.

There are three main colors of Hengbi ink: blue, red and black. The pigment components in the ink are salt-based blue and salt-based blue lotus, and the solvent is oxidized castor oil and ricinoleic acid. Because salt-based dyes are not lightfast (lightfastness is only grade 1-2), heat-resistant, acid-alkali resistant, so the durability is poor, and it has been eliminated.

The "424" blue ballpoint pen currently on the market.

and the "322" black ballpoint pen, with which the handwriting is more durable.

The main pigment of the ink is salt base blue and salt base blue lotus, and the solvent is oxidized castor oil and ricinoleic acid) and viscous substances.

The ink is made of pigments.

Connecting materials, fillers, additional materials, etc.

1. The main ingredients in the formula of oil pen ink include dyes, film formers, solvents, dispersants and other additives.

2. The basic ingredients of the formula: dye 5% 25%; Film former 5% 15%; Solvent 30% 60%; Dispersant 5% 20% ; Other additives 2% 10%.
