Description
Technical Field
The invention provides a surface scab repairing process for a multilayer solid wood floor, belonging to the technical field of floor processing and manufacturing.
Background
The multilayer solid wood floor is a new ground wood product which is produced by improvement and innovation on the basis of a solid wood single-layer floor. The multi-layer solid wood floor is a tongue-and-groove floor which is formed by using a plywood as a base material, inlaying spliced boards or slicing thin wood on a surface layer by using rare wood chips of the specification and pressing the spliced boards or the sliced thin wood by urea-formaldehyde resin glue. The panel is made of the most popular world-name and precious tree species, and is formed by bonding and pressing a plurality of layers of criss-cross wood sheets through a special process, and the whole body of the panel is of a solid wood structure.
The wood scab is the scab generated by the growing branches of the wood, and the scab which does not fall off or decay belongs to a slip knot, and the scab belongs to a dead knot. Normally, without a clear material requirement, scabbing is normal, and some wood scabbing can also produce some decorative effects. When cutting trees into panels, the scabs in the trees are also cut open. When the floor is processed, the surface plate needs to be processed by hot pressing, sticking and the like, so that a part of the surface plate is not tightly connected or the surface plate is scarred and falls off due to partial decay, and a groove is formed on the surface plate.
In the prior art, the grooves after scab shedding are repaired by using putty powder, however, the overall attractiveness of the floor is affected after the repair due to the fact that the color and the structure of the putty powder and the color and the structure of the floor are different all the time, and the strength of the floor is reduced.
Disclosure of Invention
The invention solves the defects in the prior art, and provides the process for repairing the surface scars of the solid wood multilayer floor, which has the advantages of simple steps, low cost, no influence on the strength of the repaired floor and no influence on the beauty of the original floor.
The technical scheme adopted for realizing the above purpose of the invention is as follows:
a surface scab repairing process for a solid wood floor comprises the following steps:
(1) carrying out peripheral cleaning on the fallen scab part, and cleaning a groove formed at the fallen part; for the half-fallen scabs, digging out the scabs, cleaning the periphery of the scabs, and cleaning grooves formed at the fallen parts;
(2) selecting tree branches corresponding to the outer contour according to the shape of the groove to be repaired, and slicing the branches according to the depth of the groove, wherein the thickness of the slices is the same as the depth of the groove;
(3) soaking the sliced branch pieces in ammonia water to age and discolor the branch pieces;
(4) drying the branch sheet soaked in the ammonia water to crack the branch sheet;
(5) then according to the shape of the groove, micro-cutting is carried out on the split branch sheet, so that the branch sheet can be plugged into the groove, and the branch sheet is plugged after the micro-cutting is finished;
(6) smearing putty powder on the periphery of the groove and the surface of the branch sheet to fully fill the putty powder in a gap between the branch sheet and the groove;
(7) and grinding and polishing the periphery of the groove and the surface of the branch sheet by using a sander, cleaning the surface of the putty powder and enabling the branch sheet to be flush with the surface of the floor, thus finishing the repairing process.
The tree species of the branch sheet is the same as that of the middle surface plate of the solid wood floor.
The mass concentration of the ammonia water in the step (3) is 20-30%, and the soaking time is 10-30 h.
And (4) drying the branch sheets soaked in the ammonia water by using a dryer.
Compared with the prior art, the technical scheme provided by the invention has the following advantages: according to the invention, the natural tree branches are adopted to repair the grooves after the scars fall off, and as the structure and the color of the natural tree branches are closer to the color and the structure of the solid wood floor, after the natural tree branches are soaked in ammonia water and dried, the color of the tree branches is aged and cracks are generated, so that the natural scar pattern is simulated. The repaired floor has the advantages that the strength is not affected, and the overall attractiveness of the floor is improved.
Detailed Description
The present invention will be described in detail with reference to specific examples, but the scope of the present invention is not limited to the examples.
In this embodiment, the repairing process of the present invention is described in detail by taking a multi-layer solid wood floor with an elm surface layer as an example. The base layer of the multilayer solid wood floor is made of common fast-growing poplar wood, the surface layer is made of elm wood, and 1-2% of floors are required to be subjected to scabbing repair probably in the production process.
Firstly, collecting the floors to be repaired, checking the floors one by one, cleaning the periphery of the fallen scab part by using tools such as a blade, a hook and the like, and cleaning the groove formed at the fallen part; and for the half-fallen scabs, digging out the scabs, cleaning the periphery of the scabs, and cleaning the grooves formed at the fallen parts.
Then, the branches of the dried elm are taken, the branches corresponding to the outer contour are selected according to the shape of the groove to be repaired, the branches are sliced according to the depth of the groove, the thickness of the slices is the same as the depth of the groove, and the branches with the thickness of 3 mm are uniformly sawed in the embodiment.
Soaking the branch sheet in industrial ammonia water (28 wt%) overnight, taking out after soaking, and aging and discoloring the branch sheet. And drying the limb sheet soaked in the ammonia water by using a dryer, wherein the dried limb sheet can crack to imitate the natural scab shape.
And then according to the shape of the groove, performing micro-cutting treatment on the split branch sheet to enable the branch sheet to be plugged into the groove, and plugging the branch sheet after the micro-cutting treatment is completed. And (3) smearing putty powder on the periphery of the groove and the surface of the branch sheet to ensure that the putty powder is fully filled in the gap between the branch sheet and the groove. And (4) polishing the periphery of the groove and the surface of the branch sheet by using a sander, cleaning the surface putty powder and enabling the branch sheet to be flush with the surface of the floor, thus finishing the repairing process.
