Analysis of fire rate on paper coated with the silica gel from rice husk ash

Silica element can be used as one of additional elements in a material. It is good to improve the thermal properties so it can stabilize the heat resistance of a material. The silica gel resulted from the extraction process of rice husk ash can also do the stabilization of heat resistance. This element is known to be able to reduce the fire rate in a material. In this research, the fire rate on a paper is analyzed from the result of paper coating by using the silica resulted from the extraction of rice husk ash. It is done by using the flammability test device. The silica gel used to coat the paper is obtained from variety of time during the extraction process, so it will give a difference toward the fire rate on the paper. From the research result, the paper coated by the silica gel sourced from the extraction of rice husk ash with the shortest amount of heating time has the lowest fire rate compared to other samples. It means that the percentage of silica gel obtained from the extraction of rice hush ask with various time variety is in line with the reduction of fire rate.
