What is the use of pencils from HB to 8B

Pencils are divided into two major types, H and B, which are hard in class H and soft in class B, and Hb is in between, which is a neutral pencil.

If you're a sketcher, you know for sure: tones are added layer by layer, so that you can draw three-dimensional! The higher the B number, the looser the pencil will be.

Therefore, we usually use 5-8b pencils to base our sketches, so that we can use 4b, 3b, 2b hb pencils to add layer by layer.

And if you use an HB pen as a base, then you will find that when you use a high B pen to add a tune, you can't go with this one, and it will be very slippery.

The h and b in the pencil mean ---

H=hard, B=BlackThe hardness and grayscale (gradation from white to black) of HB pencils are moderate, neither very dark nor very light. It is generally used for daily writing, elementary school students writing, sketching or sketching when sketching.

The 8b pencil is relatively soft, but darker (black) in color. It is often used in sketches and sketches that emphasize the relationship between light and dark. According to the amount of force, you can control the change of color level, the change of light and shade, and the level between black and white, so as to achieve the three-dimensional, layered, and light sense of painting.

You can draw haha! That's right, HB is a lighter pen 2B is a universal pencil, with a pen can be like how deep the painting is, like how shallow the painting is, 3b-6b are + deep used to draw deeper, and then 7b 8b is deeper, the larger the number of b, the softer the lead of the pencil, the easier it is to be pinned hb derby is a very hard pen before, I don't know if you ask if this means.

I usually start with 5B or above, continue to use 5B or above to draw big relationships, and then use 4B and below to tone layer by layer. Generally, 2B is enough, but HB is to draw very fine details, and sometimes it is not used at all. However, it depends on the user's personal situation, the hand strength is larger, the pen is smaller, the hand strength is smaller, the pen is larger.

Generally, 4b is suitable for drawing sketches, 6 8b is for black and white relationships, and 2 4b is fine.

The carbon content of HB-8B gradually increases, and the effect gradually becomes blackened.

It is used by elementary school students when they are learning to writeHB pencilIt's more appropriate.

Because beginners like to use force, it is easy to break the refill. Use 2B pencil, the refill is softer, so it will cause the color of the written words to be darker than the blur is not easy to wipe clean with an eraser, and it will also cause the surrounding area to be dirty. HB is more suitable.

H is hardness, B is blackness, H-type series is light color and hard refill, and B-type series is black and soft! HB is the depth and hardness are moderate.

Origin

1662 in Nuremberg, Germany.

Built the world's first pencil factory - Shidelou Pencil Factory. Later, the German F. Kast founded the Fabo Karst Graphite Pencil Factory in Nuremberg, using sulfur, antimony and other binders to heat and mix with graphite to make lead cores, which made a big step forward in the manufacturing technology of graphite pencil shafts.

French N.J. Kant.

For the first time, the method of washing graphite was used to improve the purity of graphite, and graphite was bonded into a refill with clay, which was called Kant's method. The foundation was laid for the pencil industry. Later, the French chemist Comte.

After trial and error, the use of clay as a hardener resulted in a refill that was stronger and more wear-resistant than before, and this method was suitable for any graphite mine and was still in use until 2019.

B stands for softness and h stands for hardness, which is the difference between them.

Pencils, which are divided into hard lead and soft lead. Hard lead is generally represented by H, with H, 2H, 3H, 4H, 5H, the hardest, and the lightest pigment. Soft lead is generally represented by B, with B, 2B, 3B, 4B, 5B, the softest, and the darkest pigment.

The gel pen is denoted by HB. That is, hard lead is not easy to break, but it is lighter to draw; Soft lead is easy to break, but the color of the drawing is darker than that of B for the exam, mainly because it is darker and can be seen clearly when grading.

The difference between 2B pencil case HB pencil is manifested in: different color depth, different hardness, different degrees of erasure, and different scope of application.

1. The color depth is different.

HB is medium-slightly black, and the black color of the 2B pencil is darker than that of the HB pencil.

2. The hardness is different.

Class H pencils, the hardness of the refill is relatively high, and Class B pencils, the refill is relatively soft, so the hardness of the HB pencil is greater than that of the 2B pencil.

3. The degree of difficulty of erasing is different.

Because HB pencils are harder, HB pencils are more difficult to erase than 2B pencils.

4. The scope of application is different.

The refill of the HB pencil has moderate hardness and is suitable for writing (writing) under general circumstances; Type B pencils, with relatively soft refills, are suitable for drawing (especially sketching), where 2B pencils are used to fill in some machine-recognizable cards, such as answer sheets.

When you buy drawing tools, you will see that there are 2B and HB pencils, so what is the difference between the two? Let's take a look.

The main differences between HB pencils and 2B pencils are the difference in blackness, composition, application and hardness. The specific analysis is as follows.

1. Blackness difference:

1) 2B pencil: The 2B pencil has a higher blackness, and the traces drawn are relatively dark.

2) HB pencil: The blackness of HB is relatively low, and the color of the drawn traces is relatively light

2. The composition is different

1) 2b pencil; The main ingredient of 2B pencil leads is graphite.

2) HB pencil: The composition of HB pencil is to add half of the graphite, and add some other colorless substances.

3. The applicable situations are coarsely different

1) 2B pencil: suitable for drawing, it can also be used to fill in some machine-recognizable cards.

2) HB pencil: suitable for writing in general, or for sketching.

4. Different hardness:

1) 2B Pencil: The lead is relatively soft.

2) HB pencil: HB type pencil refill has moderate hardness.

Expansion of Zifan Chop Town:

1. HB pencil: HB pencil is a type of pencil. where H is an abbreviation for Hardness, which means hard, B is an abbreviation for Black, which means dark or black, and Hb stands for Hardness or Gray in the middle (slightly blacker).

The HB pencil is mainly used for writing, and its handwriting color is darker than that of the H pencil, but it is easier to erase than the B pencil.

The B pencil is a soft pencil, and the depth of the 2B pencil ink is suitable for the examination to be machine-readable and easy to write. When applying a certain area of this god, the soft pencil is easier to apply evenly, and it has a metallic luster, which is not easy to break.

The above is the difference between the two, I don't know if you understand it clearly.

Pro, the difference between HB and 2B pencils 1, the blackness is different: 2B pencils have higher blackness, and the traces drawn are darker than HB pencils. 2. The hardness of the refill is different

The core of the 2B pencil is softer, while the lead of the HB pencil is very hard and not easy to break. 3. The composition of the refill is different: the main component of the 2B pencil refill is graphite, while the refill of the HB pencil has other components in addition to graphite.

4. Different uses: 2B pencil is suitable for drawing and scribbling all kinds of cards, while HB pencil is suitable for writing and marking on hard objects. Hello, I extend for you to, the pencil 2B, HB refers to the hardness of the pencil core, generally with "H" for hard pencil, "B" for soft pencil, "HB" for soft and hard pencil, "F" for pencil between HB and H.

The arrangement (from soft to hard) is 9b, 8b, 7b, 6b, 5b, 4b, 3b, 2b, b, hb, f, h, 2h, 3h, 4h, 5h, 6h, 7h, 8h, 9h, 10h and other hardness grades. Hope mine can help you <>

Do you have any other questions?

Summary. Hello, dear, here for you to find: HB and 2B are common pencil hardness grades.

They have some differences in the following aspects: Hardness: HB pencils are comparatively hard, while 2B pencils are comparatively softer.

The hardness level is an indicator used to indicate the hardness of the lead core of the pencil, the higher the hardness level, the harder the lead core, and the lines written are relatively light. The higher the softness level, the softer the lead core, and the lines written are relatively dark. Usage:

Due to the different hardness, HB and 2B pencils are suitable for different purposes. The HB pencil is suitable for general writing, drawing and tracing, with clearer lines and suitable for everyday use. 2B pencils are more suitable for painting, shading, and graffiti that require darker, darker line effects.

Erasure: Due to the varying hardness of the lead core, it is relatively easy to erase the lines of an HB pencil, while it can be more difficult to erase the lines of a 2B pencil. Soft lead cores will leave more marks in the paper fibers, and it may take more effort and a better eraser when erasing.

The HB pencil is suitable for general writing, drawing and tracing, and the lines are clearer and suitable for daily use. 2B pencils are more suitable for painting, shading, and graffiti that require darker, darker line effects. Erasure:

Due to the different hardness of the lead core, it is relatively easy to erase the lines of an HB pencil, while it can be more difficult to erase the lines of a 2B pencil. Soft lead cores will leave more marks in the paper fibers, and it may take more effort and a better eraser when erasing. (The above information ** in the headlines of today's Fiber Day).

There will be some differences in the hardness level in different countries and regions, so the specific hardness level may vary from one town to another. When choosing a pencil, you can choose the right hardness rating according to your personal writing and drawing needs. Some people may like to use pencils with different hardness ratings to achieve different line effects.

Hello, the difference between HB and 2B pencils is mainly in hardness, writing effect, and use. The main differences between them are as follows: The hardness of the lead core is different:

The hardness of the lead core of an HB pencil is between H and B and is usually medium; The hardness of the lead core of the 2B pencil is softer than that of HB, which makes it smoother to use, but it is also easier to break. Different writing results: Due to the different hardness of the lead core, the thickness and color of the lines written by HB and 2B pencils are different.

The lines written by the HB pencil are thinner and lighter in color, which is suitable for ordinary daily writing; On the other hand, the lines written by the 2B pencil are relatively thick and darker, which is suitable for drawing or writing calligraphy, and other jobs that require the effect of rolling out the lines of the shirt. Different uses: Due to differences in writing effect or availability, HB and 2B pencils are also different in terms of use scenarios.

The HB pencil is suitable for ordinary daily writing, drawing, sketching, etc., while the 2B pencil is suitable for painting, graffiti, red drawing and other scenes that need to highlight lines. In conclusion, the difference between HB and 2B pencils is mainly in terms of hardness, writing effect, and use. In practice, it is important to choose the right pencil hardness according to your personal needs and habits.
