Abstract

The invention relates to an elm plate material distressing treatment method, which comprises the following steps: (1) impregnating an elm plate material in a urea aqueous solution with a weight fraction of 5% for 2 days, spreading a layer of sodium bicarbonate on the surface of the elm plate material and drying in air at room temperature for 0-15 days; (2) washing away impurities on the surface of the elm plate material, impregnating the elm plate material in a treatment solution at the temperature of 35 DEG C for 12 hours, washing with clean water and preserving heat for 6 hours at the temperature of 58 DEG C and the relative humidity of 42%; (3) impregnating the treated elm plate material in step (2) in a urea aqueous solution with a weight concentration of 2.5% for 30 hours at the temperature of 22-30 DEG C, fishing out and washing with clean water, preserving heat for 3 hours at the temperature of 46 DEG C and the relative humidity of 32% and then preserving heat for 10 hours at the temperature of 38 DEG C and the relative humidity of 20%. The elm plate material distressing treatment method provided by the invention is simple, the treatment is carried out by targeting at the wood quality of elm wood material and the treatment effect is good.

Description

A kind of elm sheet material do old processing method

Technical field

The invention belongs to treating of wood field, what be specifically related to a kind of elm sheet material does old processing method.

Background technology

Elm plank can for furniture, vehicle, farm implements, utensil, bridge, building etc.Starch-containing and goo in bark, grinds claims elm surface.Edible in fusion flour, and for making vinegar raw material; Branch hide fiber is tough and tensile, for numb rope making rope, gunnysack or can make synthetic cotton and paper making raw material; Children tender samara and flour are puddled can steamed wheaten foods, old fruit oil-containing 25%, can for medicine with gently, chemical industry; Leaf is capable of using as feed.Elm matter weight, be a kind of excellent Furniture panel raw material, the many needs of existing furniture carry out doing old process, but elm and other timber is wooden certain difference, use that conventional to do old processing method effect bad.

Summary of the invention

What the object of this invention is to provide a kind of elm sheet material does old processing method, improves doing aging method, does old effective.

The present invention is achieved through the following technical solutions:

Elm sheet material do an old processing method, comprise the following steps:

(1), by elm sheet material operating weight mark be the aqueous solution of urea immersion treatment 2 days of 5%, then sprinkle one deck sodium bicarbonate at elm wood surface, at normal temperatures air-dry 10-15 days;

(2) impurity of elm plate surface, is washed away, use mixed liquor immersion treatment 12h at 35 DEG C of benzene sulfonic acid sodium salt 1.2 parts, 3.5 parts, potassium nitrate, sodium acid carbonate 4.2 parts, 100 parts, water by weight, use clear water is rinsed well, then 58 DEG C, be incubated 6h under the condition of relative humidity 42%;

(3) aqueous solution of urea immersion treatment 30h at 22-30 DEG C of the elm sheet material operating weight concentration 2.5%, step (2) handled well, pull rear use clean water out clean, 46 DEG C, be incubated 3h under the condition of relative humidity 32%, then 38 DEG C, be incubated 10h under the condition of relative humidity 20%.

Beneficial effect of the present invention: elm sheet material provided by the invention to do old processing method simple, process for the wooden of elm timber, treatment effect is good, the time of doing old process can also be shortened, by liquid process and isothermal holding, do old treatment effect more naturally evenly, and to do old effect on elm sheet material be continuous print, effect is naturally simple and unsophisticated, the treatment fluid that the present invention simultaneously uses is effective, without severe corrosive, strong corrosion can not be produced to elm sheet material and cause elm timber intensity to decline, ensure that the merit of elm sheet material.Process through each step, treatment effect is good simultaneously, can not cause cracking, and can promote the anti-corrosion capability of elm after process, and elm goods are stale-proof for 10 years.

Detailed description of the invention

Elm sheet material do an old processing method, comprise the following steps:

(1), by elm sheet material operating weight mark be the aqueous solution of urea immersion treatment 2 days of 5%, then sprinkle one deck sodium bicarbonate at elm wood surface, at normal temperatures air-dry 10-15 days;

(2) impurity of elm plate surface, is washed away, use mixed liquor immersion treatment 12h at 35 DEG C of benzene sulfonic acid sodium salt 1.2 parts, 3.5 parts, potassium nitrate, sodium acid carbonate 4.2 parts, 100 parts, water by weight, use clear water is rinsed well, then 58 DEG C, be incubated 6h under the condition of relative humidity 42%;

(3) aqueous solution of urea immersion treatment 30h at 22-30 DEG C of the elm sheet material operating weight concentration 2.5%, step (2) handled well, pull rear use clean water out clean, 46 DEG C, be incubated 3h under the condition of relative humidity 32%, then 38 DEG C, be incubated 10h under the condition of relative humidity 20%.
