Manufacturing method of salix mongolica dyed hard wood

Abstract

The invention relates to a manufacturing method of salix mongolica dyed hard wood, using salix mongolica as raw material to manufacture dimensional lumber with density being 0.8-1.1 and expanding the application range thereof; the implementation process comprises the followings steps: (1) manufacturing salix mongolica strips into flat and peeled salix mongolica strands by a laminating method; (2) washing the strands with circulating water and bleaching; (3) drying the strands to water content of 20%-25%; (4) dying the strands; (5) using modified phenol gum for gumming the strands; (6) drying the strands to water content of 12%-15% after gumming; (7) using a cold pressing method to compact the compositive blank in a die with using unit pressure being 550-650kg / cm<2>; (8) causing the blank to be glued and solidified into integral salix mongolica dyed hard wood at the temperature of 140 DEG C to 145 DEG C; (9) processing and reforming the salix mongolica dyed hard wood into acceptable products with uniform specification. The invention provides a new hard wood for woodwork industry.

Description

technical field [0001] The invention relates to the field of man-made board manufacture, in particular to a method for manufacturing dyed hard wood whose density can reach 0.8-1.1 using Salix salix as a raw material. Background technique [0002] At present, the manufacture of man-made boards uses wood as the main raw material. Through different wood reorganization methods, it is made into various boards such as plywood, blockboard, particle board, etc., which consumes a lot of forest resources every year. my country's forest resources are scarce. There is a serious shortage of hard natural wood. After the implementation of the "Natural Forest Protection Project", the hard wood used in the production of wood products such as solid wood flooring and furniture mainly relies on imports to solve the shortage of supply and rising prices. This situation will restrict the development of the wood product industry for a long time. develop. [0003] Salix salix is ​​a desert plant, a s...

Problems solved by technology

However, because the diameter of the branches of Salix salix is ​​too small, generally about 1-3 cm, it is difficult to peel them off. The existing wood-based panel manufacturing methods cannot use a large amount of Salix salix as the main raw material. The Enthusiasm of Farmers and Herdsmen in Desert Areas to Plant Salix
