Abstract
The invention discloses a kind of method of hydrogen peroxide bleaching timber, step is as follows：(1) solution even of following mass percent concentration is mixed into bleaching agent：80%-90% hydrogen peroxide, 0.5%-1.0% watery hydrochloric acid, 1.0%-1.5% sodium carbonate and 5%-15% ammoniacal liquor；(2) on timber brushing step (1) bleaching agent, it is fully penetrated into timber；(3) 5min is stood at room temperature, sprinkles wood powder emery cloth wiped clean；(4) bleaching agent of brushing step (1) again, timber starts to bleach；(5) fully wash, be wiped repeatedly totally with immersion emery cloth after bleaching.The present invention is very good for the bleaching of timber, has the advantages that to be used conveniently and safely, cost is low, color inhibition.
Description
Technical field
The present invention relates to Wood Bleaching, more particularly to a kind of method of hydrogen peroxide bleaching timber.
Background technology
Wood furniture elegant in appearance is made, particularly the wood furniture of light color, wooden color used must be pure white consistent.But in actual production,
Not only different wood colors differs greatly, even if same timber, also can be because with " Heisui River line " and black speckle etc., causing furniture being made etc.
Color differs, and influences outward appearance, influences benefit.In addition, after erosion of the timber by stain fungus and mould, original color is changed, this
Color change is referred to as discoloration.After stain fungus or mould intrusion timber, the nutriment of wood cell intracavitary is absorbed, but does not decompose the material of cell membrane, at it
Discoloration can only be caused during whole show.It common are sapwood and become cinerous, be blue-stain.Also have and cause timber to be in rufous spot by stain fungus,
It is erythema；Also it is variegated be separated by be miscellaneous spot etc..These spots of wood surface, can bring uneven disadvantage to coating color and luster.Especially applying
When adoring into light-coloured transparent color, will make the decoration performance of wood product surface reduces, so the facestock that such timber is unfit to do light woodwork is used.If
It when covering with paint, lacquer, colour wash, etc. dark Transparent color, if blue-stain or spot can be covered, can also use, but often be required to carry out colorant match with pigment or dyestuff,
To make up the defect caused by it.The timber of discoloration can be only used to dark application or opaque application.But, in recent years, the confession of high-quality timber
It should measure and gradually decrease, force people clear-coated to carry out using those pollution materials and discoloration material, therefore the material that will change colour bleaches into the timber of qualified color
Seem more and more important.Wood Bleaching is also referred to as timber decolouring, and the purpose of Wood Bleaching is, by the lighter of wood surface, to reduce wood surface
The difference of each site color depth, makes color uniformity.So the bleaching of the no paper of the bleaching of timber, cloth is such harsh, and it need not reach
Such high whiteness.Suitably bleaching paper, cloth method it is a lot, such as heating bleaching, bleach in closed indoor Sulfur sootiness, by several medicines
Product are mixed for bleaching etc., but its effect is not very good for the bleaching of timber, and complex operation, time-consuming.Except
Outside the above method, the method for suitable Wood Bleaching is also a lot.
The content of the invention
It is an object of the invention to provide a kind of method of hydrogen peroxide bleaching timber.
A kind of method of hydrogen peroxide bleaching timber of the present invention, comprises the following steps：
(1) solution even of following mass percent concentration is mixed into bleaching agent：80%-90% hydrogen peroxide, 0.5%-1.0% watery hydrochloric acid, 1.0%-1.5%
Sodium carbonate and 5%-15% ammoniacal liquor；
(2) on timber brushing step (1) bleaching agent, it is fully penetrated into timber；
(3) 5min is stood at room temperature, sprinkles wood powder emery cloth wiped clean；
(4) bleaching agent of brushing step (1) again, timber starts to bleach；
(5) fully to wash, be wiped repeatedly totally with immersion emery cloth after bleaching.
The beneficial effects of the invention are as follows：The present invention is very good for the bleaching of timber, has the advantages that to be used conveniently and safely, cost is low, color inhibition.
