Abstract
A modification treatment method for paulownia veneer includes the process of clear water cooking for several times alkali solution cooling, heating soaking and rinsing and natural air drying. The method has excellent degreasing and plasticizing effects and can eliminate the interstitial matter in wood without injuring lignocellulose and raise the bending strength obviously without affecting the tensile strength. The method makes the produce stable in color and easy for further treatment, such as painting, gluing, etc.
Description
The invention belongs to the processing technique field of timber, particularly relate to the modification processing method of veneer.
Paulownia wood is the timber that a kind of growth cycle is short, in light weight, deformation rate is little, wood grain is good, is applicable to make middle and high shelves furniture.In order to improve the utilization rate of paulownia wood resource, with tung board (veneer) more rudimentary sheet material or the spliced sheet material of corner small powder are carried out veneer, can improve the use class of inferior paulownia wood.But on existing market, because the color and luster of tung board itself is darker, color stability is relatively poor, and is easy to change, and veneer finished product damaged more is not easy to processing such as brushing, gummed; And the processing method that adopts existing other timber is used for paulownia wood, and the easy damaged wood fibre causes damage intensity, is not suitable for a large amount of uses, has limited the tung board selling price.
The purpose of this invention is to provide a kind of modification processing method of tung board, it is low to have processing cost, does not damage wood fibre, can reach the purpose that prevents the variable color of tung board finished product and improve folding (labor) intensity.
The objective of the invention is to realize by the following technical solutions: tung board is adopted repeatedly clear water boiling, alkaline solution boiling, adds the method that heat soaking rinsing and natural airing combine.
The concrete technological process of processing method of the present invention is:
Wet tung board after the firm slicing is immersed in the tank, water is heated to boiling, promptly more than 100 ℃, generally must not surpass 120 ℃,, will become dirty water emptying veneer boiling 10-60 minute; Add clean water again and proceed boiling, as follows circulate 3-15 time, the time of each boiling slightly increases progressively successively, promptly after once time slightly be longer than before once.Do not soak when filling out body when had poly-pentose, tannic acid etc. in the water through sampling observation, again with water: hydrogen peroxide: formaldehyde is 100 by weight: 1-5: the mixed solution of 0.1-0.5 ratio adds the immersion tank, the pH value of solution should be controlled alkalescent, be heated to the water boiling, boiling veneer 10-50 minute, emptying mixed liquor then; Veneer in temperature is 60-80 ℃ water purification, soaked 20-60 minute, but rinsing is gone out the remaining alkalies in the veneer, prevent wooden influence; By pulling veneer in the water out, paging is at the indoor natural airing of no sunlight.
Handle tung board through the inventive method good degreasing and plasticization are arranged, can remove colloid in wooden and poly-pentose, tannic acid etc. soaks and fills out body, and do not damage wood fibre, its product no color or smell, folding (labor) intensity significantly improves, and tensile strength is unaffected, and color stability is better, upright silk (year synthetic fibre) is obvious, decorative pattern is soft, is easy to processing such as covering with paint, gummed; Have that the processing method cost is low, technology is simple, easy row.Every cubic metre of tung board can improve more than 4000 yuans than the unit price of not handling tung board, and production cost increases by 50 yuan of less thaies, remarkable in economical benefits.
The invention will be further described below in conjunction with embodiment:
Embodiment 1:
Wet tung board after the firm slicing piled up in order put into tank together, with the whole submergence veneers of water purification, with boiler the water in the tank is heated to boiling, boiling is 20 minutes in about 100 ℃ water, drain only becoming dirty water, add water purification again and proceed boiling, as follows circulate 10 times, and the time of each boiling slightly increases progressively successively, in water, there has not been poly-pentose, tannic acid etc. soak when filling out body, again by (weight portion) water: hydrogen peroxide: formaldehyde is that 100: 1: 0.1 proportioning concentration adds the immersion tank, and boiling is 50 minutes behind the ebuillition of heated, then the emptying mixed liquor; Fill up water purification again, be warmed up to 60 ℃, soaked 40 minutes, by pulling veneer in the water out, paging is at indoor 40 hours natural airings of no sunlight.
