摘要:
The present invention provides a system, method and apparatus for producing fire rated doors having added strength, better finishing and low cost manufacturing flexibility. The fire rated doors are made from two panels “sandwiched” together. An optional interior layer (e.g., fire resistant material, lead sheeting, steel or Kevlar) can be added between the door panels for various purposes. Splines, stiles or sticks are inserted in longitudinal channels in the door panels to provide assistance in aligning the door panels and greater hardware holding strength. An intumescent banding material concealed by a banding material around the perimeter of the door seals the door within its frame during a fire. The door design and the automated manufacturing process provide greater design choice, reduced cost and faster fabrication.
摘要:
An extrudable cement-based material formed from a mixture that includes cement, water, gypsum, secondary materials, reinforcement fibers and rheology modifying agent. The extrudable cement-based material is a lightweight material that has a density in the range of about 1.4 to 2.4 g/cm3, a compressive strength in the range of about 5 to 100 MPa, and a flexural strength in the range of about 5 to 35 MPa. Note that the cement may contain gypsum such that the gypsum is not added to the mixture.

A lightweight thermal insulating cement-based material is formed from a mixture that includes cement, water and a foaming agent. The foaming agent can be an aluminum powder or a surfactant. The insulating material has a maximum use temperature of about 900 degrees Celsius or more.
摘要:
A composite product includes gypsum in an amount of 60 to 90% by weight, fibers in an amount of 1.5 to 26% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight. The composite is caused or allowed to cure to form a cured composite. The cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel. The fire resistant component may include a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, or a door insert.

A high temperature lightweight thermal insulating material is formed from a mixture that includes cement or silica sand, water and a foaming agent. The foaming agent can be an aluminum powder or a surfactant. The insulating material has a maximum use temperature greater than about 600 degrees Celsius.
