Description
Technical field
The present invention relates to be specially a kind of manufacturing equipment and using method thereof of multi-layer co-extruded fibre reinforced plastic composite board with plastics or with film or the sheet material products field of the material production of mecystasis.
Background technology
At present, plastic plate is divided into individual layer usually, three layers and five layers, individual layer sheet material manufacturing equipment is by a single screw extrusion machine, a flat mouthful extrusion die, one cover three-roller calendar, cooling calibrator, hauling machine, plate trimming machine, the production line that device such as sheet cutting machine is formed, the monolayer plastic sheet material of this device fabrication, no latticed fiber reinforcement on the structure, three-layer plastic plate production equipment is by the flat mouthful extrusion die of a single screw extrusion machine and two or two single screw extrusion machines and two flat mouth extrusion dies, a single layer fibre unwinding device, one cover three-roller calendar, cooling calibrator, hauling machine, plate trimming machine, the production line that device such as sheet cutting machine is formed, the three-layer plastic sheet material of this device fabrication, the intermediate layer of structure is latticed fortifying fibre, two-layer up and down is plastics, because fibrage places the middle position of sheet material section, when sheet material is subjected to evenly load, do not have the tension effect, but produce deformation along with the stretching of plastics, do not have the effect of counter-bending distortion.Five laminate material manufacturing equipments are by the flat mouthful extrusion die of three single screw extrusion machines and three or two single screw extrusion machines and three flat mouth extrusion dies, a double-deck fiber unwinding device, one cover three-roller calendar, cooling calibrator, hauling machine, plate trimming machine, the production line that device such as sheet cutting machine is formed, five layers of plastic plate of this device fabrication, from the center to outside be followed successively by central core, inferior middle level, the intermediate layer, inferior skin and skin, central core wherein, intermediate layer and skin all are plastic layers, inferior middle level and time skin all are latticed fortifying fibre layers, namely have three-layer plastic and two-layer fiber, five layers of plastic plate are because fibrage places inferior middle level and time skin of sheet material section, what no matter sheet material was subjected to is evenly load or load, the fibrage of stress surface can both play the effect of part tension, and part improves bending strength.In actual applications, sheet material is as structural material, its section all must play the effect of resistance to compression and tension, and the plastic layer in the existing plastic plate does not partly have to strengthen the flexible material that belongs to low elastic modulus and low the moment of inertia material, under pressure and pulling force and the acting in conjunction of heat expansion power that load produces, existing plastic plate section structure very easily produces deformation, then make metabolies such as sheet material bends, warpage, contraction, elongation, can't satisfy the instructions for use of building template, building wall board, platform floor, furniture panel etc.
