[Abstract]:Objective to understand the hygienic condition of blackboard in school classroom. Methods the color and material of 1695 blackboards in middle and high schools in Ningbo urban area were investigated, and 294 blackboards were randomly selected for size, surface breakage, podium setting and blackboard lamp installation. Classroom daylighting direction and measurement of reflection coefficient when blackboard lights are turned on, off (or without). Results the blackboard color and material were mostly black frosted glass, followed by dark green, white magnetic metal, black cement and wood, and the qualified rate of blackboard size was only 14.97%. The qualified rate of surface reflection coefficient of blackboard lamp is 75.00% when turned on (or without), and the installation rate of blackboard lamp is 62.59%. The blackboard surface color, material and classroom lighting direction are better than that of dark green magnetic metal and both sides, respectively. Blackboard lamp has good effect on average vertical illumination of blackboard. Conclusion the blackboard design of the school classroom in Zhengzhou should be strengthened in the construction of hygiene supervision and management.
