Description

Technical Field

[0001] The utility model relates to the technical field of resin production, in particular to nitrogen supply equipment for resin production. Background Art

[0002] Resin generally refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. Broadly speaking, any polymer compound that can be used as a raw material for plastic product processing is called a resin. Resins are divided into natural resins and synthetic resins. Natural resins refer to amorphous organic substances obtained from secretions of plants and animals in nature, such as rosin, amber, and shellac. Synthetic resins refer to resin products obtained by chemical synthesis of simple organic substances or chemical reactions of certain natural products, such as phenolic resins and polyvinyl chloride resins. Synthetic resins are the main components of plastics.

[0003] The use of nitrogen is crucial during resin processing, especially in the synthesis of acrylic resins. This is because acrylic resins are typically synthesized through free radical polymerization. In this process, the initiator decomposes upon heating to produce free radicals, which in turn break double bonds and polymerize into resin.

[0004] First of all, the resin needs nitrogen to participate in the reaction during production, but the existing nitrogen is generally stored in nitrogen storage tanks. After a long time, impurities will be produced, and it will be impure during the transportation process, resulting in the chemical effect produced when reacting with the resin is not obvious.
