Description

Technical Field

[0001] The invention relates to the technical field of flame retardant performance detection, and in particular to a flame retardant performance detection device for polymer materials. Background Art

[0002] Polymer materials, also known as polymer materials, are polymer molecular chains that are connected by covalent bonds to atoms and are connected in a simple structural unit and repeated manner. The molecular chains are connected by secondary bonds, and copolymers are formed by the polymerization of two or more monomers. Flame retardancy is one of the important properties of polymer materials. Existing flame retardant tests need to be carried out in a special laboratory through dedicated flame retardant testing equipment. However, the price and use cost of flame retardant testing equipment are high, and it is not suitable for on-site sampling of flame retardant material products in the workshop.
