Abstract
The invention discloses a formula for bleaching wood and a using method of the formula. The formula is formed by mixing the following solutions in the same amount: 20 to 25 percent ammonia water and 30 to 35 percent hydrogen peroxide. The using method comprises the following steps: (1) mixing the 20 to 25 percent ammonia water and the 30 to 35 percent hydrogen peroxide in the same amount for later use; (2) brushing and coating the mixed solution obtained in the step (1) on the wood so that the mixed solution fully penetrates into the wood; and (3) after the wood becomes white slowly and bleaching treatment is performed, fully washing the wood with water, repeatedly wiping the wood by using submerged abrasive cloth, fully and repeatedly wiping and cleaning substances obtained by bleaching treatment. The ammonia water of the formula is reacted with chromophoric groups, such as tannic acid, and the hydrogen peroxide has a bleach function (oxygen ions with oxidation property can be easily decomposed when the hydrogen peroxide meets the ammonia water or an alkali); the formula and the using method are particularly suitable for bleaching the wood with dark color and removing spots from the wood. According to the formula and the using method thereof, the effect on bleaching the wood is quite ideal by mixing the ammonia water and the hydrogen peroxide; the using method is easy to operate; labor and time are not wasted.
Description
Technical field
The present invention relates to bleach the method for timber, especially a kind of formula and using method thereof of bleaching timber.
Background technology
Timber is subject to after the erosion of stain fungus and mould, and variation has occurred original color, and this change color is called variable color.Stain fungus or mould are invaded after timber, absorb the nutriment in wood cell chamber, but do not decompose the material of cell membrane, in its whole show process, can only cause variable color.Common are sapwood and become cinerous, be blue-stain.Also have by stain fungus and cause that timber is rufous spot, is erythema; Also have variegated be separated by be assorted spot etc.
These spots of wood surface, bring inhomogeneous disadvantage can to coating color and luster.Especially in the time covering with paint, lacquer, colour wash, etc. into light-coloured transparent look, will make the decorate properties of wood product surface reduce, use so this type of timber is unfit to do the plane materiel of light woodwork.If while covering with paint, lacquer, colour wash, etc. dark Transparent color, if blue-stain or spot can be covered, also can use, but often all need to carry out colorant match with pigment or dyestuff, to make up the defect that it is caused.
The timber of variable color only can be for dark application or opaque application.But in recent years, the supply of high-quality timber reduces gradually, force people to utilize those pollution materials and variable color material to carry out clear-coated, the timber of therefore variable color material being bleached into qualified color seems more and more important.Wood Bleaching is also referred to as timber decolouring, and the object of Wood Bleaching is that the color of wood surface is shoaled, and reduces the difference of the each site color depth of wood surface, makes color uniformity.
So the bleaching of timber does not have paper, cloth bleaching harshness like that, does not need to reach high whiteness like that.The method of suitable bleaching paper, cloth is a lot, as the bleaching of heating, in the sootiness such as airtight indoor Sulfur bleaching, several medicines are mixed for bleaching etc., but its effect is not very good for the bleaching of timber, and complicated operation, time-consuming.Except said method, the method for suitable Wood Bleaching is also a lot.
Summary of the invention
The object of this invention is to provide a kind of formula and using method thereof of bleaching timber.
The formula of this bleaching timber and using method thereof, be made up of following solution mixed in equal amounts:
The ammoniacal liquor of 20%～25% concentration, the hydrogen peroxide of 30%～35% concentration;
Above concentration all refers to mass percent concentration.
Bleach a using method for the formula of timber, form by accepting step:
1. the hydrogen peroxide equivalent proportioning of the ammoniacal liquor of 20%～25% concentration and 30%～35% concentration is mixed for subsequent use;
2. above-mentioned mixed liquor is 1. brushed on timber, allow mixed liquor fully be penetrated in timber and to go;
3. timber slowly starts to bleach, and fully washing after bleaching, with the wiping repeatedly of immersion emery cloth, by bleaching material out wiped clean fully again;
Above concentration all refers to mass percent concentration.
Ammoniacal liquor and hydrogen peroxide incorporation time are in 30min.
The beneficial effect of the invention:
Hydrogen peroxide is being commonly called as of hydrogen peroxide, and sterling is transparent viscous liquid, is slightly blue.The aqueous solution is subacidity, and the commodity of selling on market are generally 30% and 3% the aqueous solution.Hydrogen peroxide can evenly mix with arbitrary proportion with water, and character is very unstable, easily resolves into water and oxygen, has oxidation, but while running into strong oxidizer, it is again a kind of reducing agent, is corrosive.It is mainly as the bleaching agent of the industries such as weaving, paper, food, disinfectant, the anticorrisive agent etc. of medical industry.Because adopt hydrogen peroxide method to carry out at normal temperatures, just can obtain effective bleaching effect within the utmost point short time;
Ammoniacal liquor of the present invention reacts with chromophoric groups such as tannic acid, hydrogen peroxide bleaching (hydrogen peroxide runs into ammoniacal liquor or alkali more easily decomposites the oxonium ion with oxidation susceptibility), the spot that this method is specially adapted to bleach the darker timber of color and removes timber.The present invention mixes with hydrogen peroxide by ammoniacal liquor, and its effect is come very good for the bleaching of timber, and simple to operate and do not take a lot of work not time-consuming.
