摘要 |
<p>The sheet has an adhesive primer layer on one of main surfaces of the sheet. A fireproof coating comprising expandable graphite is deposited on the adhesive primer layer by fluidized bed spray deposition or hopper deposition. A layer of paint is deposited on the fireproof coating. The expandable graphite has a trigger temperature ranging from 160 degree Celsius to 220 degree Celsius. Local dry matter basis weight of the expandable graphite is 80 grams per square meter in any point having a developed surface ranging from 1 to 2 square centimeters.
