Wood bleaching method based on microelectronic technology

Abstract

The invention discloses a wood bleaching method based on a microelectronic technology, and relates to the technical field of microelectronics. The method requires the following raw materials in parts by mass: wood; 15-17 parts of a penetrant; 3-5 parts of anhydrous sulfuric acid; 2-4 parts of magnesium carbonate; 5-7 parts of borax; 3-4 parts of glycerol; 9-11 parts of urea; 800-1000 parts of hydrogen peroxide; 1.5-2.5 parts of ammonium bicarbonate; 0.5-1.5 parts of sodium persulfate; and 5-11 parts of an ionic liquid-based protective agent. Through use of the ionic liquid-based protective agent, wood is pretreated during wood bleaching, so that lignin can be selectively dissolved out, fibers can be loosened, the swelling degree is improved, subsequent bleaching agent permeation is facilitated, through cooperative use of a fiber protective agent and the penetrant, a fiber protective layer is formed on the surface of the wood during bleaching, excessive yellowing during the bleaching is avoided, meanwhile, the penetrant can help penetration of a bleaching agent, black ribs generated on the surface of wood after bleaching are reduced during wood bleaching, and the stability of the wood during bleaching is improved.

Description

technical field [0001] The invention relates to the field of microelectronic technology, in particular to a wood bleaching method based on microelectronic technology. Background technique [0002] Microelectronics technology is the core technology of high-tech and information industry. With the progress and development of society, the field of microelectronics application is becoming more and more extensive. In wood processing, microelectronics technology will also be used for operation. [0003] Among them, due to the fast growth of artificial forests, the early maturity, loose material, uneven material color, dark tone, and the discoloration and pollution of wood during storage and processing, it is necessary to make wood ornaments when making wood. Bleaching is used to remove the natural uneven color of wood and stains caused by other reasons, but when bleaching existing wood, due to its own fiber layer structure, the bleaching solvent cannot be fully absorbed inside the ...

Problems solved by technology

[0003] Among them, due to the fast growth of artificial forests, the early maturity, loose material, uneven material color, dark tone, and the discoloration and pollution of wood during storage and processing, it is necessary to make wood ornaments when making wood. Bleaching is used to remove the natural uneven color of wood and stains caused by other reasons, but when bleaching existing wood, due to its own fiber layer structure, the bleaching solvent cannot be fully absorbed inside the wood, making The bleaching efficiency of wood is low, and due to the strong concentration of bleaching solvent, the bleached wood is prone to yellowing, which has a negative impact on the aesthetics of the wood

[0004] In order to solve the above problems, the inventor proposed a wood bleaching method based on microelectronic technology, which has the advantages of improving bleaching efficiency and avoiding yellowing, and solved the problem of low efficiency and easy yellowing of existing wood during bleaching. Disadvantages, when using this method for wood bleaching, it is guaranteed to improve the bleaching efficiency and the whiteness of the wood
