Abstract
This invention relates to a black pencil stationary field, which joins the carbon powder into the pencil materials, wherein the carbon powder is the remains of the carbon after burning the plants. Then it grinds the carbon to be put into the lead core, which makes the written words darker.
Description
A kind of Black pencil belongs to the stationery field.
Existing pencil is made up of lead for retractable pencil and rod, and lead for retractable pencil is made up of graphite and earth, and this pencil has the not really black shortcoming of writing out of word.
Purpose of the present invention just is to overcome above-mentioned weak point, thereby provides a kind of word that writes out black a kind of Black pencil.
The object of the present invention is achieved like this, mainly be when making lead for retractable pencil, in the starting material of making lead for retractable pencil, add powdered carbon again, powdered carbon is exactly that trees or other plant are burnt the remaining charcoal in back, again this powdered carbon is milled into powder, powdered carbon is very black, so add the lead for retractable pencil of making behind the powdered carbon partly again when making traditional lead for retractable pencil, the word that writes out is just black, thus the black purpose of word that the present invention has been reached write out.
Advantage of the present invention is: added powdered carbon partly again in the starting material of making traditional lead for retractable pencil after, have to make the black advantage of writing out of word.
The present invention is further illustrated below in conjunction with drawings and Examples.
Figure of description is a structure iron of the present invention.
In Figure of description: 1. rod 2. lead for retractable pencils 3. powdered carbons
In Figure of description: rod (1) be enclosed in lead for retractable pencil around, rod is the length the same with lead for retractable pencil, rod is circle or angular type, rod mainly plays a part to allow holds and makes lead for retractable pencil firm, makes the not effect of frangibility of lead for retractable pencil.Lead for retractable pencil (2) also comprises in the powdered carbon (3), and lead for retractable pencil is in the centre of rod, and lead for retractable pencil also can be contained in other the pipe and use, and lead for retractable pencil is made up of materials such as graphite, earth, powdered carbons, lead for retractable pencil mainly play a part to write and the word that plays a part to write out black.Powdered carbon (3) is the some of lead for retractable pencil, and powdered carbon is burnt the remaining charcoal in back by plant, the powder of wearing into again, main rise be blended in the lead for retractable pencil after, the black effect of word that lead for retractable pencil is write out.
Claims (2)
- The rod of a Black pencil (1) be enclosed in lead for retractable pencil around, it is characterized in that in making the material of lead for retractable pencil, adding powdered carbon (3).
- 2. Black pencil according to claim 1 is characterized in that adding powdered carbon (3) in the material of making lead for retractable pencil, and powdered carbon is exactly that trees are burnt the remaining charcoal in back, again this charcoal is worn into powder.
