Problems solved by technology

However, as a fast-growing wood, fir is loose in material, has significant water absorption expansion, and strong internal stress. It is generally suitable for construction and furniture industries, and is not suitable for outdoor applications. How to treat fir to make it more suitable for outdoor applications , after searching, no one has been found to be interested in it

Embodiment Construction

[0015] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments: First, the leftovers of fir logs with medium and small diameters or large-diameter fir that meet the specifications are cut to length as needed or according to the rational utilization of raw materials, and then enter the carbonization kiln for ventilated well-shaped Pile them up layer by layer, close the kiln door, turn on the heat source, and gradually raise the temperature from the kiln to 80°C. After the fir wood is dry, immediately raise the temperature to above 130°C. Sampling and visually inspect the carbonization degree of the fir wood or weigh it. The light brown color of the fir wood is Slight carbonization, medium brown is medium carbonization, dark brown is heavy carbonization is not advisable, the equilibrium moisture content of Chinese fir is almost 1 / 2 of that of ordinary dry carbonization, when the weight loss of Chin...

Abstract

The invention relates to an outdoor fir finished-material manufacturing method. A fir is cut, dried and carbonized, and then the fir is also sawed and sliced into long materials which are combined, glued, pressed, solidified, cooled and discharged, etc. to be made into square, trapezium or triangle shape fir long materials (2) which are lightly or moderately carbonized and are all vertically arranged. The long materials (2) are adhered to waterproof glue layers (1) one by one and by intervals to be pressed into single-layer or multi-layer materials which are used for making outdoor pleasure grounds and play grounds, etc. establishments or other apparatuses. A bond adopted by the method is waterproof and an internal stress of the wood is small. The method has the advantage that a warp distortion is difficult to happen and creates conditions for more ideal outdoor application of small-diameter firs.

Description

technical field [0001] The invention relates to a production method of fir laminated timber, in particular to a production method of fir laminated timber which is not easily deformed and suitable for outdoor use. Background technique [0002] Chinese fir has strong adaptability and is widely distributed in my country. It is fast-growing, beautiful in wood grain, and fine in wood. It is used as the main raw material in the construction industry and furniture industry. In recent years, countries all over the world pay attention to forest protection, restrict and ban felling, and timber is in short supply. However, the artificial fir forest planted in my country for many years has a considerable amount of thinning, and has broad prospects for use. It is an effective way to use it. CN2561566 discloses Mr. Zhang Benlong's "Small diameter fir integrated board" is an example. However, as a fast-growing wood, fir is loose in material, has significant water absorption expansion, and...
