Description
Technical field
The present invention relates to a kind of pressing hydraulic press, especially relate to a kind of fiberboard pressing hydraulic press.
Technical background
Fiberboard has another name called density board, is with wood fibre or other plant cellulose fiber for raw material, applies the wood-based plate that Lauxite or other adhesive be suitable for are made.Fiberboard is the desirable raw material of the high-end products such as high-grade gift wrap, automotive trim liner, electric appliance circuits pallet, shoemaking, furniture, its density is high, good waterproof performance, folding, any surface finish, bright color, good toughness.
The preparation process of existing fiberboard: fiber separation → slurry process → plate blank molding → hot pressing → post-processed.1. fiber separation.Also known as slurrying, it is process pulping raw material being separated into fiber.Defibration method can divide Mechanical Method and the large class of blasting procedure two, and wherein Mechanical Method divides again thermal machine method, chemical mechanical pulping and pure Mechanical Method.Thermal machine method is first by raw material hot water or saturated vapor process, fiber intercellular layer is made to soften or be partly dissolved, fiber is separated into through mechanical force under normal pressure or condition of high voltage, then through disk refiner fine grinding (the fine cardboard slurrying of dry method is generally without fine grinding), the fiber pulp that this method is produced, fiber shape is complete, intertexture is strong, and drainability is good, and yield is high, softwood pulp yield can reach 90 ~ 95%, and power consumption is little; Fiber length after fine grinding shortens, and specific area increases, outer and end brooming, and water swellability improves, and soft, plasticity increases, and intertexture is good;
2. slurry process.Namely according to product purpose, waterproof, enhancing, the process such as fire-resistant and anticorrosion is carried out respectively, to improve the relevant performance of finished product.The paraffin wax emulsions process of hard, semi-hardboard slurry improves resistance to water, and soft board slurry both can use rosin milk, also can use wax-rosin emulsion.Apply waterproofing agent to carry out in stock tank or continuous size vat.Reinforcing agent for strengthening process is wanted can be water-soluble, by fibers adsorption, and can adapt to hot pressing or the drying process of fiberboard, the multiplex phenolic resin glue of hardboard;
3. plate blank molding has wet moulding and the large class of dry-press process two, soft board and most of hard plate wet moulding; Medium-density plate and part hard plate dry-press process.Wet moulding low concentration slurry, forms slab through dewatering gradually.Dry-press process mostly adopts air forming machine.The dried fibres of paraffin and adhesive (phenolic resins) will be applied, send into spreading head by air-flow, and make dry fiber evenly drop on pad by means of fiber deadweight and the effect of padding off the net vacuum tank and form slab on the net;
4. hot pressing.Wet production hardboard need be 5 MPas with pressure, and dry method is 7 MPas, can reduce bending strength when exceeding this pressure.Pressure needed for semidry method, between therebetween, is 6 MPas.Wet shaping slab is after drying pressed into hardboard, and pressure will up to 10 MPas.Wetpressing temperature used is 200 ~ 220 DEG C.Without drying stage during dry method pressurization, temperature is as the criterion can make Rapid adhesive curing, generally adopts 180 ~ 200 DEG C; In hot pressing, top layer and the sandwich layer of slab there will be the temperature difference, and the Midst density slab watch core layer temperature difference that thickness is larger can reach 40 ~ 60 DEG C, affects sandwich layer resin solidification rate.The temperature difference is eliminated in available conventional heating and high-frequency heating, and shortens pressing cycle;
5. post-processed.Wet method and semidry method fiberboard need through heat treatment and conditioning after hot-pressing, and dry-process fiberboard does not then need directly to carry out conditioning through Overheating Treatment.Medium density fibre board (MDF) surface needs sanding, and softboard surface needs fluting to burrow sometimes, and hardboard does lining used time surface can open " V " shape groove or bar groove.
At present, the fiberboard that my company independently researches and develops has adopted the task equipment production line balance oneself researched and developed, but fiberboard is when the process of the pressurization of pressing hydraulic press, can only pressurize one block of sheet material, so often just needs multiple stage machine to work simultaneously and just can reach output.And easily there is plastic deformation in the frame seat of pressing hydraulic press, edge's wing of pressing plate is bent and locally easily occur groove mark, cause pressing plate to pass to the pressure of goods and liquid measure uneven, fiberboard there will be the problems such as local charing, therefore brings inconvenience to enterprise's production.
