ABSTRACT:
The present invention contemplates water-bearing silicate materials achieved by modifying the basic method of essentially reacting water glass with calcium chloride to bind the free water into solid form without adversely affecting the basic chemical and physical structure of the original product. The material is then dried by using a wicking agent, such as cellulose sponge, adding an anhydrous salt to the material to form a crystalline hydrate, or adding calcium oxide or calcium hydroxide to the material to form a microstructure that physically retains the water. The material is then incorporated into a fire protection contained in which the material forms the outermost wall of the container, a light-weight porous material such as urethane foam and intermediate layer, and a phase change material with a melting point of about 70 degrees F. to 125 degrees F. forms the innermost wall.
