Embodiment 1

[0030] A kind of processing method of whole bamboo compact floor comprises the steps:

[0031] Step 1: Take the bamboo section with a wall thickness of 19-22mm, cut into slices, remove internal nodes, soften and flatten to make flat bamboo slices, and then planed by double-sided planing to make thickness control 17mm whole bamboo floor blank, spare;

[0032] Step 2: Neatly stack the whole bamboo floor blanks obtained in step 1 in a metal tank, press a weight on the top layer of the stack of whole bamboo floor blanks, dilute the water-soluble phenolic resin and water at a volume ratio of 1:1.5, After mixing thoroughly, pour in metal tank, the liquid level of glue is higher than whole bamboo floor blank stacking top layer 10cm, closes the opening of metal tank; The formula of described water-soluble phenolic resin: the mass ratio of phenol, formaldehyde and NaOH is 1: 2.9:0.33, cured product content 48wt%, free formaldehyde content<0.16wt%, resin pH value 8.9;

[0033] Step 3:...

Embodiment 2

[0042] Step 1: Take the bamboo section with a wall thickness of 19-22mm, cut into slices, remove internal nodes, soften and flatten to make flat bamboo slices, and then planed by double-sided planing to make thickness control 17mm whole bamboo floor blank, spare;

[0043] Step 2: Neatly stack the whole bamboo floor blanks obtained in step 1 in a metal tank, press with a weight on the top layer of the stack of whole bamboo floor blanks, dilute the water-soluble phenolic resin and water at a volume ratio of 1:2, After mixing thoroughly, pour in metal tank, the liquid level of glue is higher than whole bamboo floor blank stacking top layer 10cm, closes the opening of metal tank; The formula of described water-soluble phenolic resin: the mass ratio of phenol, formaldehyde and NaOH is 1: 2.9:0.33, cured product content 48wt%, free formaldehyde content<0.16wt%, resin pH value 8.9;

[0044] Step 3: Open the ball valve switch on the top of the closed metal tank connected to the air c...

Embodiment 3

[0053] Step 1: Take the bamboo section with a wall thickness of 19-22mm, cut into slices, remove internal nodes, soften and flatten to make flat bamboo slices, and then planed by double-sided planing to make thickness control 17mm whole bamboo floor blank, spare;

[0054] Step 2: Place the whole bamboo floor blanks obtained in step 1 neatly in the metal tank, press the weight on the top layer of the stack of whole bamboo floor blanks, dilute the water-soluble phenolic resin and water at a volume ratio of 1:1.8, After mixing thoroughly, pour in metal tank, the liquid level of glue is higher than whole bamboo floor blank stacking top layer 10cm, closes the opening of metal tank; The formula of described water-soluble phenolic resin: the mass ratio of phenol, formaldehyde and NaOH is 1: 2.9:0.33, cured product content 48wt%, free formaldehyde content<0.16wt%, resin pH value 8.9;

[0055] Step 3: Open the ball valve switch on the top of the closed metal tank and the air compresso...

Abstract

The invention discloses a machining method for whole bamboo dense floors. Firstly, fresh bamboo sections are manufactured into flat plate bamboo chips after the procedures of chip cutting, inner segment removing, softening and flattening, the flat plate bamboo chips are planed through a pressuring planer, and then whole bamboo floor blanks are manufactured; then, after the whole bamboo floor blanks are subjected to pressure impregnation and glue drainage, the whole bamboo floor blanks are stacked in a steel solidification tank in order, and the steel solidification tank is fed into a prepress for pressurizing and densifying; and finally, the steel solidification tank in which the whole bamboo floor blanks are stacked is fed into a wood drying kiln for drying and solidifying, after the steel solidification tank is placed for 10-20 days at room temperature, the whole bamboo floor blanks are fed into a matcher and a double-end profiler for machining, and the finished whole bamboo dense floors are manufactured after the procedures of sanding and varnishing are conducted. Internal stress generated due to high-temperature softening in flattened whole bamboo floors can be eliminated, the dimensional stability of the whole bamboo floor products can be improved, the probability of occurrence of buckling deformation of the whole bamboo floor products can be reduced, and therefore wide market development prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of bamboo processing, and in particular relates to a processing method for a whole bamboo dense floor. Background technique [0002] Using the bamboo high temperature softening technology to prepare the whole bamboo floor, although there are many advantages such as high utilization rate of bamboo and beautiful appearance of the product; but there are still disadvantages of large bamboo stress and easy warping and deformation of the product, which affects the range of use and the use of the whole bamboo floor. field. [0003] The flattened whole bamboo floor blank is impregnated with phenolic resin glue by the method of pressure impregnation; and then the finished whole bamboo dense floor is made by using the curing technology of the steel curing tank. This technology can eliminate the internal stress caused by high temperature softening inside the flattened bamboo floor, improve the dimensional stability of...
