Embodiment 1

[0057] This process includes the following steps:

[0058] A. Sorting: Classify the original veneer / square according to the variety, wood grain, color and tree number, and inspect and classify;

[0059] B. Blanching: Add sodium silicate, hydrogen peroxide and caustic soda in proportion to the bleaching liquid. The bleaching liquid can be reused and the interval between repeated use is 3 days. The cooking liquid is heated and the temperature of the blanching liquid is raised to 60°C, and then the sorted veneer / cubic is put into the blanching tank in batches for treatment, and blanched for 6 hours to obtain the blanched veneer / cubic;

[0060] C. Dyeing: Dyeing mixture is added to the dyeing vat, and the dyeing mixture can be reused and the interval between reuse is 3 days. The dyeing vat uses steam indirect heating to heat the dyeing mixture and raise the temperature of the dyeing mixture to 90 ℃, then put the bleached veneer / square into the dye vat, and dye for more than 8 hou...

Embodiment 2

[0069] This process includes the following steps:

[0070] A. Sorting: Classify the original veneer / square according to the variety, wood grain, color and tree number, and inspect and classify;

[0071] B. Blanching: Add sodium silicate, hydrogen peroxide and caustic soda in proportion to the bleaching liquid. The bleaching liquid can be reused and the interval between repeated use is 3 days. The cooking liquid is heated and the temperature of the blanching liquid is raised to 55°C, and then the sorted veneer / cubic is put into the blanching tank in batches for treatment, and blanched for 6 hours to obtain the blanched veneer / cubic;

[0072] C. Dyeing: the dyeing vat is added with dyeing mixture, the dyeing mixture can be reused and the interval of reuse is 3 days, the dyeing vat uses steam indirect heating to heat the dyeing mixture and raise the temperature of the dyeing mixture to 85 ℃, then put the bleached veneer / square into the dye vat, dye for more than 8 hours, and obt...

Embodiment 3

[0081] This process includes the following steps:

[0082] A. Sorting: Classify the original veneer / square according to the variety, wood grain, color and tree number, and inspect and classify;

[0083] B. Blanching: Add sodium silicate, hydrogen peroxide and caustic soda in proportion to the bleaching liquid. The bleaching liquid can be reused and the interval of repeated use is 5 days. The cooking liquid is heated and the temperature of the blanching liquid is raised to 65°C, and then the sorted veneer / cubic is put into the blanching tank in batches for treatment, and blanched for 6 hours to obtain the blanched veneer / cubic;

[0084] C. Dyeing: The dyeing vat is added with a dyeing mixture, which can be reused and the interval between reuse is 5 days. The dyeing vat uses steam indirect heating to heat the dyeing mixture and raise the temperature of the dyeing mixture to 95 ℃, then put the bleached veneer / square into the dye vat, and dye for more than 8 hours to obtain a dye...

Abstract

The invention belongs to the technical field of wood veneer/batten manufacturing, and particularly relates to a dyeing technology for a wood veneer/batten. The dyeing technology solves the problem that the existing technology is not reasonable in design and the like. The dyeing technology for the wood veneer/batten comprises the following steps that A, separation is conducted; B, kiering is conducted; C, dyeing is conducted; D, water is removed; F, drying is conducted; and F, post-treatment is conducted. The dyeing technology has the beneficial effects that firstly, removing resin oil, a mineral line, spots, cracks and the like is the purpose of kiering, the color required by a customer is achieved, the color of the wood veneer is whiter and whiter, and the hand feeling is more comfortable and softer; secondly, the technology is simple and easy to control; thirdly, the quality and structural stability of products are improved, and practicability is higher; and fourthly, the dyeing quality is improved.

Description

technical field [0001] The invention belongs to the technical field of veneer or wood square manufacturing, and in particular relates to a veneer / square dyeing process. Background technique [0002] The dyeing of veneer and wood is generally processed through dyeing equipment. [0003] For example, the Chinese patent literature discloses a production process of scientific veneer [application number: 201410835789.2], which specifically includes the following steps: (1) truncation; (2) rotary cutting; (3) cutting; (4) drying; (5) Sorting; (6) Dyeing; (7) Drying; (8) Repairing; (9) Forming; (10) Gluing; (11) Pressing; (12) Timber making; (13) Slicing ; (14) finished product repair; (15) inspection; (16) packing into storage. Compared with the existing technology, this solution solves the problems of rigid texture, unnatural stripes and blunt color transition of the existing scientific and technological veneer. The process of the solution is simple, and the veneer processed by...
