Abstract
The invention discloses a method for producing carbonized-surface solid-wood multilayer floor. The method comprises the following steps that: solid-wood floor blank and wood-chip surface material with needed specification are produced firsr; the wood-chip surface material is dried according to different wood types and different requirements on the color; the wood-chip surface material is carbonized in vacuum under the conditions of high temperature and high humidity; and then the carbonized-surface solid-wood multilayer floor is obtained through the steps of cutting, maintaining, patching, thermally pressing, maintaining, striping, matching, coating and packaging finished products. The method has the advantages of improving the stability and weather resistance of multilayer solid-wood floor, particularly the applicability to the areas in a atrocious weather condition, obviously improving deformation-resisting capability, providing more possibility for improving the product quality of the solid-wood multilayer floor and increasing the selection of surface-material wood species, design and color, prolonging the serive life of the wood floor and expanding the application range of the solid-wood multilayer floor.
Description
Technical field
The present invention relates to a kind of production method of solid wood multi-layer floor with charring surface.
Background technology
Solid wood multi-layer floor is natural with it, the texture of environmental protection and nature and become the main material of indoor and outdoor decoration.But in use,, add in the use maintenance and improper use because that timber is handled in earlier stage is insufficient, make timber floor cracking, distortion etc. often occur, therefore to how improving the dimensionally stable on floor, reducing floor cracking phenomena in use, is that the floor produces the problem that faces.
At present, the production process of solid wood multi-layer floor is generally: lining paster → hot pressing → health that drying is good → open bar → sanding → tongue and groove → application → finished product packing.Wherein the drying of lining is used usual manner, drying loses the Free water in the lining, reach 6%～8% moisture content, and under this usual manner, handle the still very strong activity of tool (swollen is one of wood feature) of wood chip, under the humidity conditions of higher, wood chip still can be out of shape or ftractures because of suction (tide), and the while nutrient is undecomposed, therefore the damp-warm syndrome conditions permit still also is easy to damage by worms.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of solid wood multi-layer floor with charring surface makes the solid wood multi-layer floor with charring surface dimensionally stable, can reduce timber floor and produce distortion, cracking because of the variation of environment, and have insect protected, corrosion-resistant effect.
Purpose of the present invention is achieved through the following technical solutions.
A kind of production method of solid wood multi-layer floor with charring surface, it is characterized in that: produce solid wooden floor board blank and required specification wood chip lining earlier, require the wood chip lining is carried out the drying processing according to wood kind and color then, the wood chip lining is handled in charing under vacuum state, through cutting, veneer, hot pressing, health, opening bar, sanding, tongue and groove, application, obtain solid wood multi-layer floor with charring surface again.
Described dry the processing is to be dried to moisture content 10～15% under the common drying of lining.
Described under vacuum state charing treated side material package draw together following steps:
1) the wood chip lining is separated stacking by per 30～50mm one deck with plumbous net, push up most and put a plumbous net, add or do not add light briquetting, put into carbonizer according to wood chip lining situation;
2) with vacuum to 0.20 in the kiln～0.25bar;
3) add steam readjustment humidity, making has 70%～90% air humidity in the kiln, and keeps the interior humidity of kiln to be warming up to 100 ℃ continuously under 70%～90% condition;
4) step heat preservation, and maximum temperature is no more than 180 ℃, and required time is 4～12 hours;
5) charing is carried out isostasy and final vacuum and air equilibrium after finishing, and makes the external and internal pressure unanimity just can open kiln;
6) cooling naturally behind the kiln discharge, the charing processing finishes.
Divide four-stage that kiln temperature is raised to 120 ℃～180 ℃ in the described step 4).
The present invention compared with prior art has the following advantages:
The present invention is owing to be under vacuum state, through high temperature, the wood chip lining is handled in charing under the condition of high humidity, be exactly in fact by being vacuum under negative pressure and the hot conditions, under the hot conditions, molecular water in the lumen of wood chip lining is spun off, it is most of active that cell is lost, shape after the dehydration of committed cell chamber, make most of organic nutrient dehydration coking in the wood chip lining simultaneously, lose nutritional labeling, to the tightr arrangement of the iuntercellular that makes the wood chip lining, and because of its cytoactive reduction, the swollen coefficient diminishes, make the wood chip lining in different environment, keep beautiful appearance, make its distortion minimum simultaneously, and reduce and ftracture, using in different regions like this and also can obtaining fine quality assurance is that weatherability is strengthened, this shows, the present invention is under vacuum (negative pressure) condition, under through certain high temperature (140 ℃～180 ℃) condition, the long-time pyrolysis of wood chip lining is finalized the design, make moisture and the degraded of the organic principle in the wood chip lining in the cell of wood chip lining, reduce the internal stress of wood chip lining, cytoactive is reduced, and reach the swollen that reduces the wood chip lining, to reach the stable of wood chip lining size, minimizing wood chip lining produces distortion because of the variation of environment, cracking.Simultaneously under the state of high temperature, anoxic, the wood chip lining has produced complicated physics, chemical reaction in carbonizer, make the organic nutrient forfeiture in the wood chip lining, thereby on the link of food chain, suppress the existence of mushroom and termite, play insect protected, corrosion-resistant effect.
The specific embodiment
Production method to solid wood multi-layer floor with charring surface of the present invention describes in further detail below.
The production method of solid wood multi-layer floor with charring surface of the present invention is to produce earlier solid wooden floor board blank and required specification wood chip lining, require the wood chip lining is carried out the drying processing according to wood kind and color then, the wood chip lining is handled in charing under vacuum state, again through cutting, veneer, hot pressing, health, opening bar, sanding, tongue and groove, application, obtain solid wood multi-layer floor with charring surface, wherein dry the processing is to be dried to moisture content 10～15% under the common drying of lining.
Charing treated side material package is drawn together following steps under vacuum state:
1) the wood chip lining is separated stacking by per 30～50mm one deck with plumbous net, push up most and put a plumbous net, add or do not add light briquetting, put into carbonizer according to wood chip lining situation;
2) with vacuum to 0.20 in the kiln～0.25bar;
3) add steam readjustment humidity, making has 70%～90% air humidity in the kiln, and keeps the interior humidity of kiln to be warming up to 100 ℃ continuously under 70%～90% condition;
