Embodiment 1

[0029] Embodiment 1: a kind of bamboo dyeing method, it comprises the following steps:

[0030] (1) Drying: Dry the bamboo slats to adjust the moisture content to 6-7%;

[0031] (2) Penetrating dyeing: place the dried bamboo slats in the pressure furnace and seal the pressure furnace, start the high-pressure pump to feed the dyeing water into the pressure furnace until the pressure reaches 4-5MPa, so that the dyeing water penetrates along the bamboo fiber Inside the bamboo slats, the pressure is maintained for 2 days. During this period, the pressure in the pressure furnace is detected by a detector. If it is too low, the high-pressure pump is automatically activated to feed dyeing water into the pressure furnace. When the pressure reaches a predetermined value, the high-pressure pump is automatically turned off.

[0032] (3) Re-drying: pump the dyeing water out of the pressure furnace, then take out the bamboo board from the pressure furnace and place it in the drying room fo...

Embodiment 2

[0033] Embodiment 2: a kind of bamboo dyeing method, it comprises the following steps:

[0034] (1) Drying: Dry the bamboo slats to adjust the moisture content to 8-9%;

[0035] (2) Penetrating dyeing: place the dried bamboo slats in the pressure furnace and seal the pressure furnace, start the high-pressure pump to feed the dyeing water into the pressure furnace until the pressure reaches 5-6MPa, so that the dyeing water penetrates along the bamboo fiber Inside the bamboo slats, the pressure is maintained for 2.5 days. During this period, the pressure in the pressure furnace is detected by a detector. If it is too low, the high-pressure pump is automatically activated to feed dyeing water into the pressure furnace. When the pressure reaches a predetermined value, the high-pressure pump is automatically turned off.

[0036] (3) Re-drying: pump the dyeing water out of the pressure furnace, then take out the bamboo board from the pressure furnace and place it in the drying room ...

Embodiment 3

[0037] Embodiment 3: a kind of bamboo dyeing method, it comprises the following steps:

[0038] (1) Drying: Dry the bamboo slats to adjust the moisture content to 9-10%;

[0039] (2) Penetrating dyeing: place the dried bamboo slats in the pressure furnace and seal the pressure furnace, start the high-pressure pump to feed the dyeing water into the pressure furnace until the pressure reaches 5-6MPa, so that the dyeing water penetrates along the bamboo fiber Inside the bamboo slats, the pressure is maintained for 3 days. During this period, the pressure in the pressure furnace is detected by a detector. If it is too low, the high-pressure pump is automatically activated to feed dyeing water into the pressure furnace. When the pressure reaches a predetermined value, the high-pressure pump is automatically turned off.

[0040] (3) Re-drying: pump the dyeing water out of the pressure furnace, then take out the bamboo board from the pressure furnace and place it in the drying room f...

Abstract

The invention relates to bamboo wood processing, and especially relates to a bamboo sheet making method, a dyeing method, a dyeing water, and a preparation method of the dyeing water. The bamboo wood dyeing method comprises the following steps: 1, drying: drying bamboo board splints to adjust the water content to 6-10%; and 2, permeating: putting the dried bamboo board splints in a pressure furnace, sealing the pressure furnace, pumping the dyeing water into the pressure furnace through a high pressure pump until the pressure reaches 4-6MPa, allowing the dyeing water to permeate into the bamboo board splints along bamboo fibers, maintaining the pressure for 2-3d, detecting the pressure in the pressure furnace through a detector, automatically pumping the dyeing water into the pressure furnace through the high pressure pump if the pressure is too low, and automatically stopping the high pressure pump if the pressure reaches a predetermined value. The dyeing method has the advantages of simple process and easy enforcement, allows the dyeing water to permeate into and be attached to the core of bamboo wood along the bamboo fibers in the dyeing process in order to make the color loss of the bamboo wood difficult, and is in favor of producing colorful bamboo products.

Description

technical field [0001] The invention relates to bamboo processing, in particular to a preparation method of bamboo boards, a dyeing method, dyeing water, and a preparation method of dyeing water. Background technique [0002] Staining agents in the prior art, such as the high-coloring paint disclosed in the invention patent application with the application publication number CN103436135A, are particularly suitable as the coating on the surface of bamboo and wood products. However, this coating is easy to fade, especially in the finished product. When the surface is damaged, the color of the product itself is easy to show. Contents of the invention [0003] The purpose of the present invention is to provide a method for dyeing bamboo, which can effectively infiltrate dyeing water into the interior of the bamboo, so that the bamboo is not easy to fade, and even if the surface of the bamboo is damaged, it is not easy to show the color of the bamboo itself. [0004] Above-men...
