Description

Technical Field

[0001] The utility model relates to the technical field of fire retardant coating testing, in particular to a steel structure fire retardant coating performance testing device. Background Art

[0002] Fire retardant coating is a special coating used on the surface of combustible substrates to reduce the flammability of the coated material surface, block the rapid spread of fire, and improve the fire resistance of the coated material. Special coatings applied to the surface of combustible substrates to change the surface combustion characteristics of the material and block the rapid spread of fire; or applied to building components to improve the fire resistance of the components are called fire retardant coatings.

[0003] After the production of steel structures is completed, they still need to be treated with fireproofing, that is, fire-retardant coatings will be applied on the surface of the steel structures to improve the fire resistance of the steel structures. In order to accurately grasp the fire resistance of steel structure fire-retardant coatings, it is necessary to conduct fire tests on fire-retardant coatings. In order to effectively simulate the on-site environment of a fire, technicians in the relevant technical field proposed a "Steel Structure Fire Retardant Coating Performance Test Device" with application number CN202022615303.8. In this application document, the flame of burning firewood is used to test the combustion of samples placed on the sample rack with the help of a fire port. However, the technical solution in this application document is still insufficient. The device needs to be loaded and unloaded with the help of fire tongs tools. The distance between the flame and the sample is uncontrollable, and it is difficult to control the heating intensity of the sample. To this end, we proposed a steel structure fire retardant coating performance test device. Utility Model Content
