MAKING FIRE RESISTANT CABINET |
摘要 |
The body of a cabinet for storing temperature-sensitive articles such as magnetic discs and tapes is built by a process which involves the successive steps of (i) fabricating an internal skin; (ii) attaching so-called "phase-change" material to the skin; (iii) applying insulative polyurethane foam in-situ to the structure of step (ii); (iv) casting concrete or the like water-bearing material around the structure of step (iii); and (v) completing the outer finishing skin. Thus the conventional "double-box" structure is avoided. The door for the cabinet can be built by a similar sequence in which "phase-change" material, insulative form and water-bearing layers are applied successively to a pan forming the internal face of the door. |
