| titleOfInvention | Production system and method for improving flame retardant property of oriented strand board by adding flame retardant in multiple stages |
| abstract | The invention discloses a production system and a method for improving the flame retardant property of an oriented strand board by adding a flame retardant in multiple stages. This shaving board production system includes: the system comprises a wet flake storage bin, a wet flake conveying device II, a drying device, a dry flake conveying device I, a screening device, a dry flake storage bin, a dry flake conveying device II, a glue mixing device, a paving device, a hot-pressing device, a post-processing device after hot pressing and a fire retardant spraying structure; the fire retardant spraying structure is connected with the wet shaving piece conveying device II, the dry shaving piece conveying device I and/or the dry shaving piece conveying device II, the glue mixing device, the paving device and/or the hot pressing device. The invention adopts multi-process spraying, the flake is fully absorbed, the flame retardant is uniformly distributed, and the loss and waste of the flame retardant caused by unqualified flame retardance of the plate or too much spraying, too late absorption of the surface of the wood shavings and the loss of the flame retardant are avoided. The flame-retardant shaving board obtained by treatment has excellent flame-retardant performance; the physical properties are equivalent to the physical properties of the particle boards produced by pressing with non-added flame retardants. |
