Abstract
Methods/Materials
First, I drilled a hole into the center of 5 wooden boards, all the same dimensions. I coated the top of each board with a different colors of fire protection, namely white, black, green, brown, and red. I placed each board on two supports (coating up - hole down) and inserted a temperature probe into the hole. I positioned a 500-watt heat lamp above the board and recorded the temperature every second for 30 minutes. Then, I turned the lamp off and recorded the temperature every second for 60 minutes. I replaced the lamp with a gas torch and repeated the experiments for the white and black boards.
Results
Using curve fit parameters the heating and cooling curves were compared. The heating and cooling curves show a consistent sequence of the five colors: white, green, red, brown, and black. The white board reflected the most heat and released the heat most slowly. The black board absorbed the most heat and released the heat most quickly.
Conclusions/Discussion
An explanation of the observed results has been developed to explain the evolution of temperature on the surface of a fire protective coating over time.
The project determines the effect of color on characteristics of a heat barrier material.
