Abstract
The present invention relates to woodwork production, and is especially fast artificial timber curing process. The artificial timber curing process includes adhering molding boards with insulating layer to the two sides of the combined artificial timber blank, adding steel frame outside the molding boards, fastening the steel frame with screws, applying high frequency electric field parallel to the gluing layer of the blank across the blank to heat, maintaining the pressure before demolding. The present invention has the energy of the electric field applied directly onto the adhesive molecules for easy heating and curing, and thus possesses advantages of short heating and storing time, short curing time, high production efficiency and convenient operation.
Description
Technical field
The present invention relates to the quick curing of a kind of method of woodwork production and processing, particularly a kind of imitation wood.
Background technology
In the woodwork production and processing industries; the high-quality natural timber that is used to decorate is fewer and feweri; environmental protection is also made more restriction to the felling of natural timber; people adopt the artificial fast growing wood section statining, select collocation, the gluing bonding agent, make up the method for putting into the moulding of special tool mould cure under pressure and make the imitation wood in recent years; imitation wood after the moulding has the effect of natural timber after section, be widely used for furniture, decoration field.Imitation wood's curing molding method of prior art has two kinds: the one, after the combination of gluing bonding agent, put into the special tool mould pressurization of high-frequency electrical pole plate, and impose high-frequency electric field and be placed on thermostatic chamber after heating a period of time interior 4 to 7 days, solve tool and mould then; Another kind method is after the gluing bonding agent combination, puts into the tool and mould pressurization, is placed on interior 5 days of thermostatic chamber to first quarter moon, solves tool and mould then.
The shortcoming of preceding a kind of method is: insulation board, worker's mould and processed timber integral body place high-frequency electric field, and the high-frequency electrical pole plate is parallel to coated face, and a high-frequency energy part acts on insulation board, the worker's mould, wastes energy; Under the high situation of moisture content, because steam and xanthan molecule heat its interaction process more complicated jointly, if it is improper that grasp heat time heating time, the timber internal temperature is too high to cause sapstain, wooden sustaining damage, if the short effect that does not have curing glue bonding agent again heat time heating time.Second method is because the moisture content of bringing into during the gluing bonding agent on timber, discharge at normal temperatures slowly, the moisture content height causes the adhesive solidification difficulty, and constant temperature is deposited so that the glue bonding agent solidifies for a long time, if solve tool and mould too early then can produce waster.All there is the problem that the tool and mould time is oversize, influence production efficiency that takies in said method simultaneously.
After imitation wood's moulding, the material that has is used for the slicing thin slice and needs moisture content high, the sawing that is used for that has is made wood strip, timber bar etc. and is needed moisture content low again, so its purposes of root a tree name determines its water content, and the fast curing-formed demoulding is the key link very during the imitation wood makes.
Summary of the invention
The curing that the purpose of this invention is to provide a kind of imitation wood, the technical problem that solve are the gluing bonding agents that solidifies fast in its manufacture process.
Imitation wood's of the present invention curing, parallel the worker's mould that sticks the tape insulation plate on imitation wood's assembly two sides, with rubberised layer, pull with steel framework again and be pressed in outside worker's mould, pull with the steel framework at fastening screw tension two ends at last, add the high-frequency electric field heating on imitation wood's assembly two sides, the back demoulding is deposited in pressurize, and described high-frequency electric field parallels with the rubberised layer of imitation wood's assembly.
Imitation wood's assembly of the present invention two sides, with the perpendicular face of rubberised layer positive plate and minus plate are set respectively, high-frequency electric field is applied between positive plate and the minus plate.
When imitation wood's assembly of the present invention was of a size of 2.54 * 0.63 * 0.63 meter, be 15-25 minute heat time heating time.
The pressurize resting period of the present invention is 1-8 hour.
High-frequency electric field of the present invention heat time heating time is 20 minutes.
Of the present inventionly pull assembly integral body with the steel framework after the fastening screw tension and be placed in the vacuum chamber, vacuumize earlier, then imitation wood's assembly is heated.
Vacuum in the vacuum chamber of the present invention is 0.8-0.098Mpa.
A kind of imitation wood's of the present invention curing, parallel the worker's mould that sticks the tape insulation plate on imitation wood's assembly two sides, with rubberised layer, imitation wood's assembly that will have worker's mould again is placed in the hydraulic press, add the high-frequency electric field heating on imitation wood's assembly two sides, the step-down demoulding after one hour, described high-frequency electric field parallels with the rubberised layer of imitation wood's assembly.The present invention compared with prior art, high-frequency electric field parallels with the rubberised layer of imitation wood's assembly, energy directly acts on the gluing agent molecule that connects, the gluing agent molecule that connects solidifies than the easier polarization heating of hydrone under high-frequency electric field, has reduced the wooden probability that sustains damage of Wood carbonization variable color, the energy utilization rate height, heating, resting period shorten, shorten hardening time greatly, improved production efficiency, and convenient operation and control.
