Accounting must use a carbon pen for bookkeeping, why can t a ballpoint pen?

The ballpoint pen is not conducive to preservation, and after a long time or stained with water, the word will be gone, so it is generally necessary to archive or important written materials are not allowed to be written with a ballpoint pen, while the carbon pen is relatively stable.

Accounting must use a carbon pen instead of a ballpoint pen, because ballpoint pen writing is not conducive to preservation, a long time or stained with water, the word is gone. Therefore, it is generally not allowed to be written with a ballpoint pen for archival or important written materials, while carbon pens are relatively stable.

A few common sense points to keep in mind for bookkeeping:

1) Bookkeeping must be registered in a timely manner according to the audit of correct accounting vouchers.

2) In order to make the records in the accounting book clear and tidy and prevent usurpation, the bookkeeping must be written with a blue (black) ink pen, and no pencil or ballpoint pen shall be used except for copying.

3) All kinds of account books must be registered in the order of the numbered pages, and no lines or pages are allowed. If there is a skipping line or a page separation, it should be written off with a red ink pen diagonally at the pick line or empty page, indicating the words "this line is blank" or "this page is blank", and signed or sealed by the bookkeeper.

4) When bookkeeping, the date and voucher number should be indicated for each account. Numbers, summary (summary bookkeeping can be exempted from filling in and amount.) After bookkeeping, the page number of the account book should be indicated on the accounting voucher, or the " " symbol should be marked to avoid re-recording and omission.

5) Bookkeeping, to keep clear, tidy, bookkeeping words or numbers should be upright, clear, not to the account books to rub, mend, alter or other chemical methods to change the handwriting.

6) Bookkeeping, except for the closing line, reversal, adjustment of accounts and correction of erroneous records, shall not be written in red ink, because in the accounting towel red number indicates the reversal, write-off or negative number of the blue number.

Because you have to use a fountain pen or a carbon pen to make a book, the color of the ballpoint pen is not black, and there are traces of writing.

It must be a carbon pen, a fountain pen, and basically everyone uses a pen! The ballpoint pen fades too quickly, and it is not suitable to be kept, and some accounts should be kept for 10-15 years!

There is nothing that can't be done in actual work, and you can use any pen if you want to make trouble for yourself. It is advisable to use a pen that is not easy to fade, such as a black carbon pen or a blue-black fountain pen.

No, a pen or pen is required!!

That's right! The original voucher shall not be filled in with a ballpoint pen.

Accounting Standards: In addition to the original vouchers in duplicate must be copied with a ballpoint pen, other original vouchers should be filled in with a fountain pen of blue and black ink, and shall not be filled in arbitrarily with a pencil or red ink pen.

For example, a ballpoint pen cannot be used for bank delivery slips, but ballpoint pens can be used for single wire transfers.

Except for the original vouchers in duplicate, which must be copied with a ballpoint pen, other original vouchers must be filled in with a fountain pen in blue and black ink, and shall not be filled in arbitrarily with a pencil or red ink pen. It is better not to use a ballpoint pen, because the regulations do not say that the use of ballpoint pens is allowed, nor does it say that the use of ballpoint pens is forbidden, so from now on use a signature to write down the account. The original voucher should be written with a blue or black pen, the handwriting should be clear and standardized, and the check must be filled out with a carbon pen.

Cash journal and bank journal specifications: use a fountain pen to write in blue and black ink, and do not use a ballpoint pen (except for bank copy books) or pencil writing. However, in accordance with the provisions of the red-letter reversal voucher reversal error record and the accounting system, the business registered in red-letter can be recorded in red ink.

Wrong, it should be a black pen or carbon pen.

Fountain pen extra-thin.

Blue or carbon can be used to correct something red.

Now it's all computer bookkeeping, let's use software.

First of all, you should not use ballpoint notes, you should use a blue or black carbon pen or fountain pen, and red should be used for correction!

Because the ink of the ballpoint pen is made with dye and castor oil. The oil is not easy to dry, 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 Shanghai Municipal Archives Bureau stipulates that it is forbidden to use pencils, ballpoint pens, etc. to write or sign documents. Most of the handwriting of documents written and approved with pencils, ballpoint pens, red ink, and documents typed or copied with carbon paper has faded, and some have become blurred and unrecognizable, affecting the use. This situation will become worse over time.

Any archival documents cannot be filled in with a ballpoint pen. Can only be filled with blue or blue-black ink.

From the perspective of archival protection, the durability of handwriting depends on two factors: first, whether the handwriting pigment component is durable and does not fade; The second is whether the handwriting pigment is firmly combined with the paper. The combined effect of these two factors determines the durability of the handwriting.

According to the type of pigment component of archival handwriting and the way it is combined with paper, the most durable handwriting is one with carbon black as the pigment component and fixed with the paper conjunctiva, such as ink, ink, black ink, electrostatic photocopy, etc.;

The more durable handwriting includes pigments as pigments, condensation with paper or absorption, such as color inks, blue-black inks, inks, iron salt blueprints, etc.;

The indurable handwriting is combined with dyes as pigment components in any way, such as blue-black ink, red ink, carbon paper, ballpoint pens (new ballpoint pens marked with the word "da" can be used to write archival documents, and the composition is relatively durable), ink ink, diazosalt blueprints, etc., and handwriting with any pigment component that adheres to paper, such as color pencils, graphite pencils, etc.

Filling out official documents is a matter of obscurity, but ballpoint pens will fade over time.

The archival materials filled in are to be archived and preserved, but the ballpoint pen will fade over time.

Ballpoint pen ink is a variety of volatile components, easy to eliminate with chemical solutions, after a long period of storage or moisture, it will become unrecognizable. This is not the case with rollerballs and black fountain pens.

Now the exam requirement must be a black carbon pen, the reason is that carbon pen oil contains carbon elements, which can be stored for a long time, and neither blue nor black ballpoint pen oil can meet the requirements for long-term storage.

There are more than 100 kinds of carbon elements in nature, carbon is one of them, and we call the atoms of carbon as isotopes of carbon due to the different number of neutrons. Therefore, it cannot be said that there are several types of carbon elements, but it should be said that there are several isotopes of carbon. At present, there are 12 known isotopes, ranging from carbon 8 to carbon 19, of which carbon 12 and carbon 13 are stable, and the rest are radioactive, of which carbon 14 has a half-life of 5,730 years, and the others are all less than half an hour.

In the natural world of the earth, carbon 12 accounts for the content of all carbon, and the atomic weight of carbon 13 is taken as the weighted average of the two isotopic abundances of carbon, which is generally taken when calculating. Carbon-12 is the scale used in the International System of Units to define moles, with the number of atoms contained in 12 grams of carbon-12 being 1 mole. Carbon-14 is widely used to date antiquities due to its long half-life.

In addition, there are various forms of carbon elemental existence, including crystalline elemental carbon such as diamond and graphite; There is amorphous carbon such as coal, and the physical and chemical properties of elemental carbon depend on its crystal structure. The crystal structure of high-hardness diamond and soft and smooth graphite crystal is different, and each has its own appearance, density, melting point, etc.

Carbon in life

The ink we use contains carbon.

The iron and steel around us are all a mixture of iron and carbon.

Now there is activated carbon sold on the market, which can deodorize, and some can purify water.

Now the diamond from which the glass is cut is another element of carbon.

Graphite

Graphite is jet-black and soft, making it the softest mineral in the world. The density of graphite is smaller than that of diamond, and the melting point is only 50k lower than that of diamond, which is 3773k.

In graphite crystals, the carbon atoms form covalent single bonds with sp2 hybrid orbitals and three adjacent carbon atoms, forming a hexagonal plane network structure, which in turn is connected into a lamellar structure. layer in each.

The carbon atoms all have one unaccompanied p-orbital left in the sp2 hybridization, in which there is an unpaired p-electron, and the m electrons in this carbon atom in the same layer form a large bond (bond) of m-centric m-electrons. These delocalized electrons can be found throughout the child.

Carbon atoms are active in the planar layer, so graphite has good electrical and thermal conductivity in the layered direction.

The layers of graphite are bound by intermolecular forces, so graphite is prone to sliding and cracking in a direction parallel to the layer. Graphite is soft and lubricating.

Due to the presence of free electrons in the graphite layer, graphite is chemically reactive compared to diamond.

Because graphite conducts electricity, is chemically inert, resistant to high temperatures, and is easy to form and machine, graphite is widely used to make electrodes, high-temperature thermocouples, crucibles, brushes, lubricants, and pencil leads.

Now the exam requirement must be a carbon pen or B2 pencil card, the reason is that carbon pen oil can be stored for a long time, while ballpoint pen oil cannot meet the requirements of long-term storage, so it can't. To put it bluntly, the ballpoint pen has been used for a long time, and the handwriting is easy to disappear.

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

Ballpoint pens are oil-based pens, and the handwriting will be blurry after a long time, and they cannot be stored for a long time.

Usually, the teacher will make you a habit. Prevent the use of mistakes in the high school entrance examination and college entrance examination, or the unaccustomed font that causes the font to look bad.

Black rollerballs usually contain carbon in their ink, which can keep the written words for a long time

There are two reasons for this problem:

Many exams are judged by computer scanning, and the better scanning effect is the black signature pen (also called gel pen), and the ballpoint pen scanning effect is not good;

Aesthetics, the ballpoint pen dries slowly when writing, and it will be painted everywhere if it is accidentally touched, and the surface of the roll will have a greasy feeling; The pen dries faster and the roll looks fresher.

The test paper overlapped and the pen oil was everywhere.

Ballpoint pen and ink will go out of oil!

According to this characteristic, it is not advisable to use a ballpoint pen for writing documents that are not copyable.

Of course, the lubrication of the ballpoint pen tip has an advantage, so it is better to use a ballpoint pen to copy documents!

Of course, you have to use a fountain pen, but now everyone uses a signature pen. It doesn't have to be black, blue, other colors are fine, it's just that few people use it. But don't use the red one!

Fountain pens are kept for a long time! These require documents, of course, with such tools.

A question that elementary school students know! Characters written with a ballpoint pen are prone to fading and blurring, making it impossible to preserve. The Black Carbon Pen solves this problem.

To fill it out with a very formal black carbon pen.

On the one hand, it is out of respect.

On the other hand, because the black pen fades the slowest under the same conditions and the color loss is minimal, it is necessary to fill in the important documents such as reimbursement with a black pen to avoid the inconvenience caused by your own unclarity in the future.
