Description
Affiliated technical field
The utility model relates to a kind of wood-based plate manufacturing technology, especially a kind of curved surfaces thermoplastic mould.
Background technology
In the technical field of wood-based plate, making the multiple-plate method of stalk is after just stalk is processed into veneer at present, forms through certain technology assembly glue laminated again.Veneer needs before glue laminated by the even applying glue of certain thickness, and this is the necessary condition that guarantees cementing strength between each layer veneer.The stalk multi-layer sheet that adopts traditional handicraft to produce still has the problem of two aspects not resolve:
1) bonding quality between veneer is relatively poor, in use easily from interface cracking aliquation.Because at the certain pressure compacted under, the fiber free end on surface is solidificated in the plane lamina by stalk fibre, and the fineness on surface is higher, so glue application layer thickness is difficult to evenly, is the main cause that causes stalk multi-layer sheet aliquation.
2) the stalk plate is lower to the grip force of screw.Because contained cellulose and hemicellulose are than timber height in the stalk, contained lignin is low than timber, and is so stalk plate resistance of deformation is lower, low than the timber plate to the grip force of screw.
The utility model content
The purpose of this utility model is to provide a kind of curved surfaces thermoplastic mould, is intended to utilize microwaviness to improve the uniformity of veneer top sizing layer thickness, and utilizes microwaviness to improve the stalk plate to the grip force of screw, to address the above problem.
The technical solution of the utility model is achieved in that
A kind of curved surfaces thermoplastic mould comprises upper die and lower die and base, and the upper die and lower die shape is mated adaptation mutually, and counterdie places on the base, the base support counterdie; Have the interstitial channels of passing through as saturated vapours between counterdie inner surface and the outer surface.Upper die and lower die all are that diameter is about 1.5 meters semicylinder device; The counterdie inner surface is the indent curved surfaces, and outer surface and base join; Interstitial channels runs through and spreads all over space between the whole counterdie surfaces externally and internally between described counterdie inner surface and the outer surface; Counterdie outer surface both sides upper position is provided with two saturated vapours air inlets; Counterdie outer surface bottom is provided with a discharge outlet, discharges for the condensed water of saturated vapours.
The processing method of utilizing curved surfaces thermoplastic mould to produce microwaviness stalk veneer produces the processing method of microwaviness stalk veneer, comprises the steps:
(1) pretreatment of raw material
1) raw material fragmentation, sorting
2) fiber degrease processing: at a certain temperature raw material is heated, remove the wax fat of fiber surface; Remove the fiber of wax fat to the affinity increase of adhesive, both can improve stalk plate intensity, can reduce adhesive adapted amount again;
3) raw fibre processing: employing is rubbed loose sander stalk section is rubbed the pine polishing, and raw material is processed into fiber;
(2) the fiber kiss-coating is handled
Selecting the superior larch tannin resin glue of glue performance for use is adhesive, and the adhesive consumption is 2-3%, and liquid adhesive stirs with fiber in agitator;
(3) the kiss-coating fiber is mated formation
Fiber behind the kiss-coating is mated formation in the pressure mould by certain thickness;
(4) material of mating formation is hot-forming for the plane veneer
Under certain pressure, uniform temperature and certain hour, the material of mating formation is carried out hot pressing, form the plane veneer;
(5) veneer surface plasticizing
With the plane veneer put to radius of curvature be on the indent arc end template of R, and utilize patrix that the veneer compacting is carried out the curved surface thermoplastification at the arc bed die, bed die utilizes saturated vapor to carry out heated at constant temperature, fusion time is set as requested; Because the sheet material outer surface that becomes arc is subjected to the heating of end template, institute so that the fiber in the sheet material outer surface 1.0mm thickness plastify, and owing to following the string and with curved surface bus length generation plastic elongation;
(6) plane veneer microwavinessization
Veneer is taken off from the arcuate bottom template fast, and sheet material recovers flat shape at the elastic reaction that is not plastifying part sheet material, thereby causes the surface that also plastified owing to the shortening of linear dimension produces microwaviness.
The beneficial effects of the utility model are: the microwaviness living beings veneer of the utility model production has the technical advantage of three aspects:
1) veneer surface is fine and closely woven and the existence of uniform microwaviness makes veneer top sizing thickness even, thereby makes in the multi-layer sheet production process, and only the bonding quality between the laminate increases substantially, and fundamentally eliminates the phenomenon of stalk multi-layer sheet aliquation.
When 2) multi-layer sheet was suppressed, the other side's mother metal was advanced in the mutual punching press of fine ripple between the adjacent monolayer plate, and globality increases, and had improved the various aspects of performance of sheet material.
3) bigger drag effect is deviate to have to stoping screw in fine ripple inclined-plane, has improved the grip force of stalk plate to screw.
