Abstract

The invention discloses a modification technology for enhancing anti-corrosive property of timber. The modification technology comprises the following steps: taking timer, cutting and sawing the timer; placing a sheet material in a pool filled with a novel timber anticorrosion modification liquid, taking the sheet material out, warping the sheet material by using a gauze immersed with the novel timber anticorrosion modification liquid, warping the sheet material with a preservative film, placing the material in an enclosed chamber; taking the wrapped sheet material out, removing the preservative film and gauze; placing the sheet material in a drying chamber, adjusting the temperature for drying the material; turning a temperature regulator off, after the room temperature is naturally cooled, the sheet material is taken out, and the water content of the sheet material is adjusted. The modification technology has the beneficial effect that the intensity and anticorrosion performance of the timer are enhanced, the density, hardness, bending strength and elastic modulus are good, usage performance of the timer is enhanced, service life of the timber is prolonged; the required equipment is simple, and enables large scale industrial production, timber anti-corrosive property is increased at high degree, and production cost is low.

Description

technical field [0001] The invention relates to a wood modification technology, in particular to a modification technology for enhancing wood corrosion resistance. Background technique [0002] With the development of the country's economic construction and the improvement of people's living standards, people's demand for wood is increasing. The implementation of natural forest protection projects has made the contradiction between supply and demand of timber more prominent. In order to alleviate the contradiction between supply and demand, my country has built a large area of ​​industrial plantation. Although the artificial forest wood has the advantages of fast growth and high yield, the physical and mechanical properties of the artificial fast-growing forest wood are poor, the density is low, the material is soft, and it is easy to shrink and deform. [0003] In order to expand the application range of artificial forest timber and improve the economic value of artificia...
