发明名称 System and method for coating a fire-resistant material on a substrate
摘要 A method for coating a fire-resistant substance onto a carrier veil and products containing fire-resistant substances are provided. The method includes delivering a pliable carrier veil in a traveling web, drawing the carrier veil web through a reservoir defined by a nip of two rollers and containing the fire-resistant substance, where the carrier veil is coated with the fire-resistant substance. The method also includes controlling the amount of fire-resistant substance on the carrier veil web by setting a nip dimension between the two rollers, passing the carrier veil through the nip of the two rollers and providing the fire-resistant substance as a slurry suitable to coat the veil exiting the nip with a layer effective to provide a selected fire resistance. Heat is applied to the carrier veil sufficient to accelerate a curing reaction in the fire-resistant substance. A fire-resistant product includes a glass-based web, and a magnesium oxychloride complex materially coupled to the web, where the complex includes: MgCl2.mMg(OH)2.nH2O; where m is between about 3 and about 7, and n is between about 6 and about 10.
