You do not know a few fire prevention knowledge
A Paint Tray kit typically includes a plastic or metal tray with several compartments or wells to hold different colors of paint. The kit may also include paintbrushes of various sizes, a paint roller, and sometimes even a paint palette for mixing colors. Some kits may also include other accessories such as paint sponges or paint stirrers. The purpose of a paint tray kit is to provide all the necessary tools and equipment for a person to easily and efficiently apply paint to a surface.

Finished fire retardant coatings are generally used as protective materials for flammable substrates, with certain decorative and fire-retardant properties, and are divided into two major categories, waterborne and solvent-based. The fire-retardant coating for steel structures is mainly used as a protective material for non-burning components. The coating of such fire-retardant coatings is relatively thick, and has a low density and a low thermal conductivity, so it has excellent thermal insulation properties and is divided into organic fire-retardant coatings. And inorganic fireproof coatings.
Since the assessment of the quality of <br> <br> fire retardant coating is used to retard the spread of fire, the quality of what is good fireproof paint it? What kind of criteria? According to the current point of view, the domestic total is divided into fire-resistant coating One, two, three, of course, is the best performance. The quality of fireproof coatings is mainly determined by the fireproof performance and physical and chemical properties of fireproof coatings. The fire performance includes four indicators such as flame resistance time, flame propagation ratio, weight loss, and carbonization volume, which can be determined according to national standards for large-plate combustion, tunnel combustion, and chamber combustion. The physical and chemical properties mainly include solid content, viscosity, flexibility, impact strength, adhesion, drying time and water resistance. Its technical indicators are obtained after testing according to national standards.
The thicker the fire resistance <br> <br> whether fire retardant paint coating, the more good it is fire resistance? In general this is for non-intumescent fire retardant coating it, it is difficult to rely on its own Combustible and incombustible to stop the flame from spreading. Therefore, the thicker the coating, the thicker a glaze that forms at high temperatures and the better thermal insulation of the fire retardant coating. For intumescent fire-retardant coatings, the coating is thick, expands and foams when exposed to fire, the thicker the foam layer that forms the oxygen- and heat-insulating layer, the thicker, and at the same time the [NO], [NH3], etc. groups of some nitrogen-containing fireproof coatings decompose. Increased, combined with organic free radicals, the effect of interrupting the chain lock reaction is also good. Therefore, from the standpoint of improving the fire resistance, the thicker the coating, the better.
Fire burning <br> <br> why some fire retardant paint fire will burn it? To explain this question, we first look, the base fire retardant coating, dispersion media, fire retardants, solvents and other components. Before the construction of the fire-retardant coating in the event of fire burning, in fact, the flammable liquid solvent in the fire retardant coating is burning, and the fire retardant coating base material, flame retardant and other substances will not burn. Because solvent-based fire retardant paints use organic solvents as solvent, such as No. 200 solvent gasoline, n-butanol, acetone, cyclohexanone, and toluene, these fire-proof paints can easily cause fire once they escape from the barrel. The fire-retardant paint applied on the building components can only be used to prevent fire and heat insulation after the solvent evaporates.
How are <br> <br> improve the fire resistance of building components treated with fire retardant coating fire resistance effect? With the development of science in China retardant, advanced, high-quality fire-resistant coating emerged from the forward application situation, the effect is obviously.

Fire-retardant coatings consist of paint components such as base materials (ie, film-forming substances), pigments, common paint additives, fire-retardant aids, and dispersion media. In addition to fire-retardant additives, other paint components play the same role in paints as they do in ordinary paints, but they have special requirements in terms of performance and dosage.
