Is the 2B pencil Tianjiao Tianzhuo brand credible

Be cautious as well. It is recommended to use Chinese pencils to buy genuine products, and the China National Light Industry Pencil Quality Supervision and Inspection Center has tested these pencils, and the failure rate is more than 30. In the current standardized test in China, the computer can only read the pencil handwriting with a lead core concentration of 2b, and too thick or too light will cause the failure or error of computer reading.

Most of the lead cores of counterfeit and shoddy pencils are made of a small amount of graphite doped with a large amount of clay, and the concentration and hardness of the lead core cannot meet the requirements of physical indicators, and are not suitable for computer identification. The lead of this counterfeit 2B pencil is also in danger of breaking and scratching the answer sheet.

In order to further test the impact of these counterfeit and shoddy 2B pencils on the computer's judgment scores, the relevant personnel used two unqualified pencils and one qualified pencil in the middle to conduct a scribbling test at the same time, and the same results were applied to the computer to identify, and the scores of the three test papers were 100 points, 87 points, and 99 points respectively. A few seconds for the computer to get a different score, and these few seconds can determine the fate of the candidate.

Nowadays, it is difficult to distinguish the authenticity of the first Chinese 2B pencil on the market, and people are worried about how to identify the Chinese 2B pencil. Under normal circumstances, candidates will bring one or two spare 2B pencils, most of which are purchased by candidates or parents from the market, and counterfeit 2B pencils in the market are likely to bring hidden dangers to candidates taking the test.

China's first pencil shares **** on how to identify the Chinese 2b pencil in detail, the main way to identify the real and fake Chinese 2b pencil is: 1. The surface paint of the real pencil is full and bright, while the fake paint is dark and dry; Second, the steel printed on the real pencil is printed with gold platinum and white platinum, the font is complete, the platinum degree of white platinum is high, and the fake white platinum is very dark; 3. The real pencil is printed with 2B white platinum logo on three sides, and the three signs printed are on the same horizontal plane, while the fake one is high and low, and the error is quite large. The person concerned told reporters that the pencil below the yuan is estimated to be fake, because the wholesale price of the Zhonghua brand 2B pencil is yuan.

In addition, if you pinch 10 real Chinese 2b pencils together, the height is about the same, while the fake ones are high and low, and they are extremely inconsistent. In addition, the real Chinese 2b pencil is dark red in wood, the fake head is a little red, but the inside is white, and then a closer look can be found that the real Chinese 2b pencil is hexagonal symmetrical, and the fake one is completely asymmetrical.

Several other ways to identify counterfeit 2B pencils:

The simplest thing is to look at the logo: put several pencils together and see if the "2b" sign printed on the barrel is exactly the same, and the uneven ones are fakes;

You can also look at the wood: the inside and the outside are the same, the dark red is **, and the fake is only painted red at the top, and the wood is white or light yellow after cutting, and when it is cut, it feels that the wood is very hard and easy to split;

In addition, the surface of the genuine product is finely printed, while the fake is blurry, the paint is black, and the surface is not smooth.

It's good to be cautious, but that's not the point of the exam.

It doesn't matter what brand of 2B pencil it is, the card reader can read it (even a fake one).

It's better to pay more attention to your own learning.

When I took the high school entrance examination, I used "Tianzhuo", which is not bad.

It's better to be cautious about the exam and go to the big shopping mall to buy a Chinese brand. Every year, there are candidates who block the wrong card.

It's better to be dedicated to exams.
