Features and advantages:

1). When we use chalk to write on the blackboard, we can’t see any dust. The dust-free chalk is so hygienic and clean that it can avoid occupational diseases caused by chalk bubbles entering the internal organs by breathing. 2). The dust of chalk will not be scattered on hands and clothes because of the addition of smoothing agents and binders, and we don’t need to wash our hands frequently. 3)A small amount of moisture-proofing agent is added to the dust-free chalk to ensure that long-term storage. However, ordinary chalk is easy to absorb moisture for a long time, the hardness is lowered, and the writing is easy to break. 4). Most of the blackboards used in schools are cement boards and wood boards. Due to the different smoothness of the surface of the blackboard, the degree of softness and hardness of the chalk is also different.
