Problems solved by technology

[0008] Some data show that the carbonization temperature of phenolic resin glue is as low as about 250°C after heat curing, and it collapses into ash at 400°C. Therefore, the large-scale salix wood building materials made of phenolic resin glue glued and cured have limited fire resistance.

Embodiment

[0029] Step 1: Prepare the inorganic sulfur-magnesium cement adhesive, with 10 kilograms per part by weight, each component is prepared according to the following parts by weight, lightly burned magnesium oxide 45, magnesium sulfate heptahydrate 22, sepiolite powder 8, citric acid 0.3, temperature 27 of water at 20-60°C; or, 47 of light-burned magnesium oxide, 26 of magnesium sulfate heptahydrate, 5 of sepiolite powder, 0.5 of citric acid, and 30 of water at a temperature of 20-60°C; or, of light-burned magnesia 50, magnesium sulfate heptahydrate 30, sepiolite powder 10, citric acid 0.7, water at a temperature of 20-60°C 35.

[0030] Put light-burned magnesia, magnesium sulfate heptahydrate, sepiolite powder, citric acid and water at a temperature of 20-60°C in the above weight ratio into a mixer, and stir for 5-8 minutes to obtain an inorganic sulfur-magnesium cement adhesive.

[0031] The fluidity of the inorganic sulfur-magnesium cement adhesive is tested according to exist...

Abstract

The invention discloses a fireproof salix mongolica integrated wood machining method. According to the method, an inorganic sulfur magnesium cement binding agent not containing phenol or formaldehydeis adopted for gluing laminated flat salix mongolica strips. The method comprises the steps that the inorganic sulfur magnesium cement binding agent is prepared, salix mongolica trunk branches are subjected to cutting tidying, glue immersing, cold-press pressing fit, cutting and sanding, and then finished wood is obtained. The salix mongolica integrated wood machined through the method has the prominent beneficial effects that combustion is avoided, corrosion resistance, water resistance and durability are achieved, strength is high, sound isolation and heat preservation are achieved, and machinability is good.

Description

technical field [0001] The invention relates to a method for processing refractory salix integrated wood. Background technique [0002] Salix salix is ​​a shrub plant mainly used for sand fixation. It has the characteristics of cold resistance, drought resistance, high temperature resistance, sand burial resistance, easy planting and fast growth. According to the growth habit of Salix salix, stubble must be carried out every three years, which is conducive to the germination of a large number of branches of Salix salix and promotes its growth to tall and thick, otherwise it will cause Salix salix to decay and even die. [0003] The branches of Salix salix are composed of the branches that have not been lignified and the main branches that have been lignified. The branches are usually used as animal feed, and the main branches are mainly used for industrial fuel and domestic fuel. However, the calorific value of the branches of Salix is ​​only coal About 50% of that, so it i...
