Abstract
The invention discloses a bamboo wood decolorizer. The bamboo wood decolorizer comprises, by mass, 0.1%-1% of an alkali metal sulfite compound or ammonium sulfite compound, 0.013%-0.3% of alkali metal salt and 98.5%-99.5% of solvent. The invention further discloses a usage method of the bamboo wood decolorizer. The bamboo wood decolorizer is reasonable in formula, low in cost, low in irritation, safe in use, convenient to use, and good in decoloration effect to bamboo wood which mildews and is not fresh enough. Bamboo products after decoloration is bright in color, natural in color and luster, smooth and not prone to fuzzing, clear in bamboo fiber line, free from odour, and capable of being dyed with random colors and being processed with decoration. When the bamboo wood decolorizer is used, a user can decolor the bamboo wood into different colors according to market demands.
Description
Technical field
The present invention relates to a kind of bamboo wood bleaching agent and using method thereof.
Background technology
At present, the bamboo material product uses extensively, and as building materials bamboo decoration board, bamboo curtain, bamboo tooth pick, bamboo chopsticks, bamboo floor, bamboo furniture plate, bamboo craftwork plate, bamboo planning cutting board etc., bamboo all need to bleach mildew-resistant before making these bamboo products processes.
The bleaching process of bamboo wood is mainly the processing that lignin in bamboo wood is carried out.The method of bleaching mainly contains two kinds, and a kind of is the bleaching of sloughing lignin, and another kind is the bleaching of reserve quality.In general, the bleaching of sloughing lignin can obtain the high and stable bamboo wood of whiteness, and the bleaching of reserve quality, the effect that reaches whiteness is less better.At present, the method for bleaching that bamboo wood is commonly used is the hydrogen peroxide bleaching method, the active oxygen atom that produces under alkalescence or heating condition due to hydrogen peroxide has strong oxidisability, can be with the various moulds in bamboo wood and the coloring matter oxidation in fiber, play the effect of sterilization bleaching, simultaneously hydrogen peroxide itself can with bamboo wood in some coloring matter generation redox reaction, play discoloration thereby generate colourless material.Although this kind method for bleaching has stronger bleaching and disinfecting and mildew-proof function, but because hydrogen peroxide has very strong oxidisability and reproducibility, the bamboo fiber damage is large, the bamboo wood density loss is large, and color and luster is dull, very easily corrode human body skin in the bleaching process of bamboo wood, cause work safety accident.
Summary of the invention
For solving the problems of the technologies described above, the invention provides that a kind of technique is simple, bleaching effect good, the bamboo wood bleaching agent of safe ready and the method for using this bamboo wood bleaching agent to bleach.
For achieving the above object, the technical solution used in the present invention is:
A kind of bamboo wood bleaching agent is comprised of the component of following quality percent by volume: the sulfite compound 0.1～1% of alkali metal or ammonium; Alkali metal salt 0.013～0.3%; Solvent 98.5～99.5%.

Above-mentioned solvent is aqueous solvent or oil solvent.
The using method of above-mentioned a kind of bamboo wood bleaching agent is soaked bamboo wood and is floated in the bamboo wood bleaching agent.
Further, above-mentioned soaking floated for heat and floated or cold floating, and normal pressure soaks and floats or pressurize to soak and float.
Float step above-mentioned soaking, those of ordinary skills can be according to the color and luster of bamboo wood needs bleaching, compound and consumption that the degree of depth is allocated corresponding color voluntarily; The concentration of bleaching agent, temperature and soak and float time length soak that to float the pressure size or whether pressurize be not that invention of the present invention will be put the place, and those of ordinary skills can grasp voluntarily.
Beneficial effect of the present invention: bamboo wood bleaching agent formula of the present invention is reasonable, with low cost, excitant is little, and is safe and convenient to use, especially to go mouldy, fresh not bamboo wood has good bleaching effect, bamboo product color after bleaching is fresh, the color and luster nature, smooth and phozy, the bamboo fibre lines is clear, odorless, arbitrarily painted and decoration is processed.Bamboo wood can be bleached into also depending on market demand that rice white or milky, silvery white, beautiful white, potato are white, ivory buff, can also be white middle band yellow or be with green, band is blue, band is grey, wait redly.
