Manufacturing method null of the humidification functional material which utilizes the Wakkanai formation diatomaceous earth

摘要

PURPOSE:To provide the process for producing the humidistatic function material formed by utilizing WAKKANAI stratum diatomaceous earth. One of the characteristics inherent to the porous structure of the WAKKANAI stratum diatomaceous earth lies in the humidistatic function to absorb and release moisture and this humidistatic function material is formed to exhibit the humidistatic function simply by compounding the ground matter of the above-mentioned WAKKANAI stratum diatomaceous earth with other raw materials or combining the diatomaceous earth as a filler with other materials. CONSTITUTION:Firstly, this process for producing the humidistatic function material by utilizing the WAKKANAI stratum diatomaceous earth consists in using the ground matter of the WAKKANAI diatomaceous earth alone or compounding this diatomaceous earth and other ceramic raw materials, molding the mixture to an arbitrary shape and calcining the molding. Secondly, the process for producing the humidistatic function material by utilizing the WAKKANAI stratum diatomaceous earth consists in using the ground matter of the WAKKANAI stratum diatomaceous earth alone or combining this diatomaceous earth as a filler with other materials and non-calcining the mixture.
