Description
Technical field
The present invention relates to the high-pressure drying method of rotary cut venner and to use the rotary cut venner after high-pressure drying to prepare solid wood multiple
Close the preparation method on floor.
Background technology
The preparation method of the solid wooden compound floor seen is, is composition each laminate material gluing of solid wooden compound floor, group
The operations such as base, hot pressing or Cold-press adhesion, then carry out the operation such as secondary operations such as mortice opening and surface paint and obtain.
Along with the raising of timber rotary-cut technology, the thickness of current rotary cut venner should rise to present by original 1-4mm
6-14mm, owing to the rotary-cut number of times for juggle reduces, can save the use of timber in a large number, but, the thicker list that rotary-cut goes out
Plate preparation floor during usually produced problem have:
(1) existing due to the crack, the back side of veneer, the front and back of thick core veneer differs greatly, in hot pressing thermal histories, and stress
Cannot discharge, cause sheet material to be prone to that the defect such as warpage, distortion occurs；
(2) thicker veneer easily produces more score during rotary-cut, in Process of Applying Glue, needs substantial amounts of glue
Fill score, the waste of substantial amounts of glue and the unequal phenomenon of positive and negative resin added can be caused, the most easily make
The asymmetric of positive and negative is become to produce warpage and bend even degumming defect；
(3) thicker veneer is in dry run, self the most easily produces warpage, easily causes fracture in subsequent handling, impact
The integrity of veneer.
In order to solve these problems, the most conventional solution is mainly by tenderizing veneer sheets technology in the front of veneer
Or back side fluting and reduce the method such as completeization (the most whole veneer is divided into multiple veneers) of veneer to reduce stress, lead to
Cross the means such as hot plate or high-pressure drying (as guipure compresses) are dried to control the deformation of veneer, but can not discharge follow-up completely
The thermal stress produced in hot pressing.
Summary of the invention
It is an object of the invention to provide a kind of type of respiration high-pressure drying method of rotary cut venner, the most dried rotation
Singulation intralaminar part is the most unstressed, and angularity is low, and planarization is good, and smooth surface is smooth.
The type of respiration high-pressure drying method of rotary cut venner of the present invention, it is 100-240 that rotary cut venner is placed in temperature
DEG C pressure drying machine in, repeat following type of respiration press-drying processes until its moisture content is down to less than 3%: with heating platen
To sandwich layer pressurize 0.1-3MPa, pressurize 10-40s/(mm core layer thickness) rise heating platen, 5-40s/(mm core layer thickness afterwards) after again
Secondary with heating platen to sandwich layer pressurize.
The type of respiration high-pressure drying method of above-mentioned rotary cut venner, rotary cut venner thickness is 5-14mm.
It is a further object of the present invention to provide a kind of solid wooden compound floor production method, the solid wood produced in this way is combined
Floor, angularity is low, and planarization is good, and resin added is few simultaneously.
Solid wooden compound floor production method of the present invention, described solid wooden compound floor include as the thickness of sandwich layer be
The rotary cut venner of 5-14mm, to after other each layer gluings of sandwich layer and composition solid wooden compound floor, assembly, compressing, open again
Tenon and notch prepare solid wooden compound floor；Before gluing, sandwich layer is placed in the pressure drying machine that temperature is 100-240 DEG C,
Repeat following type of respiration press-drying processes until the moisture content of sandwich layer is down to less than 3%, then sandwich layer is placed in air or people
In the environment that work is arranged, natural moisture absorption is to moisture content 6-12%；Described type of respiration press-drying processes is: add sandwich layer with heating platen
Pressure 0.1-3MPa, pressurize 10-40s/(mm core layer thickness) rise heating platen, 5-40s/(mm core layer thickness afterwards) after again with hot pressing
Sandwich layer is pressurizeed by plate.
Beneficial effects of the present invention: rotary-cut timber (veneer) stress that the present invention is directed to rotary-cut timber especially thick is difficult to release
Putting, veneer positive and negative is asymmetric and veneer easily produces the features such as score during rotary-cut, uses heating platen to be dried
Technology, is dried means by repeatedly pressurization, the type of respiration repeatedly of release so that the moisture content of rotary cut venner is down to less than 3%, and one
The score of thick veneer can be filled and led up by aspect so that rotary cut venner smooth surface, smooth, attractive in appearance, on the other hand can release
Put the thermal stress of thick core veneer, in follow-up hot pressing process, be not likely to produce deformation, it is ensured that the solid wooden compound floor of preparation
Flatness.Use repeatedly type of respiration to be dried means so that dried sandwich layer (rotary cut venner) surface does not has burr substantially simultaneously
And groove mark, it is possible to reduce glue-spread, and increase its bond properties.Repeatedly pressurization, the type of respiration repeatedly of release are dried means, also can
The veneer superficial charring phenomenon that preventing pressurizes for a long time causes.Natural moisture absorption can more readily adapt to current glue to moisture content 6-12%
The heat pressing process that plywood produces, reduces the phenomenon of coming unglued caused because of taken in excess glue.Heating platen pressurization dwell time and heat
Pressing plate release time, depending on being based on core layer thickness (unit mm).For every millimeter of core layer thickness heating platen pressurization dwell time
Being 10-40s, heating platen release time is 5-40s.Pressurization pressurize makes veneer internal moisture progressively become steam from veneer every time
Internal release, finally makes the rotary cut venner moisture content after pressurization pressurize be down to less than 3%.The when of press temperature height during pressurize
Between shorter, the when that press temperature being low, length is a little the dwell time.During temperature height, the dwell time is long, and the easy carbonization in veneer surface, to list
The outward appearance of plate and performance produce impact；When temperature is low, the time is the shortest, and veneer internal moisture can not become steam and release inside veneer
Put.Certainly, during rotary cut venner initial aqueous rate height, temperature can be higher, and the dwell time can also be longer.At the beginning of rotary cut venner
When beginning moisture content is low, temperature can be lower, and the dwell time can also be shorter
The artificial environment arranged mainly provides uniform temperature and the environment of humidity, and the humidity of natural environment is as weather, gas
Each factors such as time and change, temperature and humidity condition is manually set so that the degree of veneer moisture absorption is more stable.
Above-mentioned solid wooden compound floor production method, the single spreading amount to sandwich layer is 80-220g/m2.The feelings of glue-spread
Condition is different with the difference of glue kind, solid content and sizing equipment, and the low glue kind glue-spread of usual solid content is big, coating uniformly and
The thin required adhesive liquid quantity of coated glue layer is little.
Above-mentioned solid wooden compound floor production method, described solid wooden compound floor include two-layer, three layers, four layers, five layers, six
Layer, seven layers, eight Rotating fields, containing described sandwich layer in its structure.Due to by the sandwich layer veneer stability after above-mentioned processing method
Well, the solid wooden compound floor for various structures operates the effect that all can play steady production.
Above-mentioned solid wooden compound floor production method, described core concentration is 0.4-1.0g/cm3, close with sandwich layer adjacent layer
Degree is more than core concentration.Preferably symmetrical structure such as three layers, five layers, seven-layer structure.
