Abstract:
The primary issue with employing chalkboard is adverse consequences
of chalk-dust particles causing health complications like asthma,
dermatitis including inflammation in eyes. The contact electrification
serves as a basis. Air ionizer is utilized for electrifying chalkboard
surface on which chalk-dust particles adheres to. The chalk-dust
particle sizes targeted are in the range of PM2.5 to PM10. In this
paper, distinct types of chalkboard surfaces are reviewed based on
their place in triboelectric series and dielectric constant of the material.
Also, the mathematical calculation of the force between particles and
chalkboard is calculated using “Method of Image Charges”. After each
trial, the chalkboard surface was cleaned with a mixture of distilled
water and 70% isopropyl alcohol for the deionization of the board. The
findings would be helpful for creating a revolutionary device to make
any chalkboard dust less.
