Description

A kind of elm sheet material do old processing method

Technical field

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

Background technology

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

Summary of the invention

It is an object of the invention 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:

A kind of elm sheet material do old processing method, comprise the following steps:

(1) the aqueous solution of urea immersion treatment, by elm sheet material using weight fraction to be 5% 2 days, then spreads last layer sodium bicarbonate at elm plate surface, air-dries at normal temperatures 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 of potassium nitrate, sodium acid carbonate 4.2 parts, 100 parts of water by weight, use clear water is rinsed well, then 58 DEG C, be incubated 6h under conditions of relative humidity 42%；

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

Beneficial effects of the present invention: the elm sheet material that the present invention provides to do old processing method simple, wooden for elm timber processes, high treating effect, the time doing old process can also be shortened, processed by liquid and isothermal holding, do old treatment effect more natural uniformly, and doing old effect on elm sheet material is continuous print, effect is the simpleest and the most unsophisticated, the treatment fluid that the present invention uses simultaneously is effective, without severe corrosive, elm sheet material will not be produced strong corrosion and cause elm timber intensity to decline, it is ensured that the merit of elm sheet material.Process through each step, high treating effect simultaneously, do not result in cracking, and the anti-corrosion capability of elm after processing, can be promoted, make elm goods be stale-proof for 10 years.

Detailed description of the invention

A kind of elm sheet material do old processing method, comprise the following steps:

(1) the aqueous solution of urea immersion treatment, by elm sheet material using weight fraction to be 5% 2 days, then spreads last layer sodium bicarbonate at elm plate surface, air-dries at normal temperatures 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 of potassium nitrate, sodium acid carbonate 4.2 parts, 100 parts of water by weight, use clear water is rinsed well, then 58 DEG C, be incubated 6h under conditions of relative humidity 42%；

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