Problems solved by technology

[0002] Chalk is a tool widely used in daily life. It is generally used to write on blackboards. Ancient chalk is usually made of natural chalk, but nowadays it is replaced by other substances. The main component of chalk is calcium sulfate, which is a white The sediment is not easy to be decomposed, and the particles are larger than the dust. Now when the teacher erases the writing on the blackboard, there is a lot of dust, which will have a great impact on the teacher's body, and there are many hidden dangers. At the same time, chalk dust Can get everywhere, the environmental dust of classroom is very big, aim at above-mentioned shortcoming, the present invention has been improved
