1. sulfuric acid (H
2SO
4) as strong acid, because its density is bigger, H behind obtain solution
2SO
4Easy deposition is along with soaking the increase of timber time, owing to container leaves standstill, serious relatively in the wood corrosion of bottom when handling timber.And solution has pollution to environment.Transportation (according to hazardous materials transportation regulation transportation), to store near (avoid contact with reducing agents such as organic matter, metal dusts, forbid unlimited concentrated acid container smoking during storing or employ naked light) requirement very high.To red stain is generally all arranged after the timber preliminary treatment.
2. caustic soda (NaOH) physicochemical properties: belong to highly basic, have strong corrosivity, 30% caustic soda is a liquid under the normal temperature.Contact with acid vigorous reaction can take place, emit a large amount of heat, can corroding metal, some plastics of etch, rubber and coating.
3. hydrogen peroxide (is commonly called as hydrogen peroxide solution, molecular formula, H
2O
2) strong oxidizing property is arranged, though itself is not flammable, the oxygen that produces when decomposing can be combustion-supporting consumingly, and can set off an explosion bump, friction and the danger of combustion explosion is arranged when shaking after combustibles, organic matter contacts.
Because the strength and stiffness of fast growing material own are smaller, had a strong impact on its direct application in engineering and industry, can open up its range of application greatly and it is manufactured a kind of dalle with concavo-convex veining on surface of characteristic modelled after an antique.To carry out preliminary treatment to wood surface in wood surface Z-Correct bump mapping Z-correct first being processed; Promptly in order to process the sheet material that the surface has Z-Correct bump mapping Z-correct; Making early at first as far as possible, the late wood distinguishes; So that process the decorative wooden sheet material that the surface that meets the requirements has the natural texture concave-convex sense, be the basis that goes out Z-Correct bump mapping Z-correct in its Surface Machining so fast growing wood is softened preliminary treatment.
Employed chemical reagent strong acid in traditional timber preprocess method, highly basic are very high to the rate of corrosion of fast growing wood cell membrane; And wood cell wall is elementary cell and the basis that constitutes strength of wood and rigidity, then influences very big with traditional timber preliminary treatment chemical reagent strong acid, highly basic preliminary treatment fast growing wood to its strength and stiffness.So the damage to its cell membrane in the process of preliminary treatment fast growing wood should be paid close attention especially.
Three, summary of the invention
