Product Description Particle Board Forming Machine Quality Control of Paving Forming Molding:Pavement forming is to pave the glued dry fibers into slabs with uniform thickness and density according to process requirements, and then pre-press and saw them into specified sizes. Only when paved into qualified slabs can high-quality medium-density fiberboards be obtained. First of all, when the fibers are formed, they are required to be non-clumping, non-aggregated, evenly distributed, and naturally well interwoven. Secondly, the formed slab is required to have a certain strength and not fall apart during transportation. Third, the density of each point of the entire slab is required to be uniform, and the weight error per unit area is ±3%. Fourth, it is required that the slab should be as dense as possible to reduce the opening of the hot press. Fifth, the thickness of the forming slab is controlled between 15 and 28 times the thickness of the finished product to reduce the consumption of raw materials and adhesives. The surface core shavings after mixing with glue are sent to the surface core layer measurement silo of the paving station respectively, and then are paved separately through each paving head.The particleboard paving is a 3-layer structure paving, that is, the upper layerLower surface layer and core layer. Among them, the paving method of the upper and lower surfaces is directional paving in the length direction, with wide and long planing The perianth is laid directly on the surface; the core layer is laid horizontally with fine sub-small shavings.When it comes to the surface core layer shavings paving effect is as shown in the figure. Oriented strand board designed by our company When it comes to the core layer shavings paving effect is as shown in the figure. Oriented strand board designed by our company The paver can automatically detect the height of the board to adjust the distance between the paver head and the board so that the paver head is at Keep a small distance between the boards to prevent shavings from floating freely during the descent of the pavement, thereby Ensure paving orientation accuracy (average orientation deviation within 7°).OSB Paving Forming Process Requirements: 1. The pavement should be uniform and stable: the density and thickness deviation on the surface should be as small as possible. Control method: use a densitometer to measure the density at each point of the slab and measure the falling amount of shavings. 2. The slab structure is symmetrical: the center of the slab thickness is the symmetry plane, and the tree species, wood shaving shape, moisture content, glue amount, etc. on both sides are symmetrical 3. Reasonable slab structure Generally, the core layer station is 1/2-3/4, and the surface layer station is 1/8-1/4. As the thickness of the plate increases, the surface content decreases.
