During the teaching process of teachers, chalk dust will inevitably stick to their hands. At the same time, the particle dust floating in the air will also fall on the hair, face and neck of teachers and students, which will stimulate the skin membrane. If it is dissolved, alkaline substances will be produced, which will cause greater irritation to the skin and mucous membranes, because the environment in which human skin lives is a weakly acidic environment, which destroys the basic living environment of the skin under the action of dust alkalinity, and chalk dust makes the skin dry. , rough, accompanied by itching sensation, which makes the human body uncomfortable, and severe cases can cause acne, folliculitis, pyoderma, chapped skin and a large amount of hair loss, which affects and interferes with the normal work and life of teachers
