A free-standing solid composite intumescent structure has at least one bendable metal mesh, preferably at least two, secured on or in a bendable intumescent sheet material. The structure is bendable by a bending force into a shape at a temperature above 10 C. while retaining the bended shape when the bending force is removed. The intumescent sheet material has 10 wt % or more, based on total weight of the sheet material, of a polymeric resin; inorganic filler; and, an intumescent component. Fire protection barriers can be made from the free-standing solid composite intumescent structure, which can be used in fire protection systems where the fire protection barrier is installed on a substrate, for example steel building elements.

A lubric gel composition for personal defense is provided which includes a fatty acid at a concentration ranging from 5 wt % to 10 wt % of the composition, a thickening agent at a concentration ranging from 1.75 wt % to 8.75 wt % of the composition, a detergent at a concentration ranging from 1.03 wt % to 4.07 wt % of the composition, a surfactant at a concentration ranging from 2 wt % to 15 wt % of the composition, and water at a concentration ranging from 66 wt % to 90.21 wt % of the composition.

Disclosed is a physical-chemical composite inhibitor for controlling spontaneous combustion of low-rank coal, and methods of preparing and using the same. The composite inhibitor consists of a chelate and attapulgite, the chelate is generated by chelation of proanthocyanidin with calcium chloride. The composite inhibitor has moisture-absorbing and moisture-retaining effect, and can reduce water dissipation at low temperature. A stable oxide insulating layer such as MgO and Al.sub.2O.sub.3 insulating layer can be formed at high temperature, which can block a coal body from contacting with oxygen. In addition, the composite inhibitor can capture hydroxyl free radicals generated during the chain-cycle reaction and destroy peroxide free radicals, and can also interact with an active moiety in coal to form a stable structure such as ether linkage and hydrogen bonding, thereby achieving permanent inhibition of low-rank coal.
