Corrosion and mould resistant process for bamboos

Abstract

The invention provides a bamboo corrosion and mould resistant process with high processing efficiency. The process comprises the steps that bamboos are placed in an environment with the superheated steam pressure being 0.4-0.6 MPa and the steam temperature being 125-135 DEG C to be processed for 80-100 min; and when the bamboos are subjected to superheated steam treatment, a mould inhibitor stock solution is sprayed to steam, and 1.54 kg of the mould inhibitor stock solution is sprayed to every 1 m3 of the bamboos. The corrosion and mould resistant process has the beneficial effects that under the high-pressure and superheated steam state, the surfaces of the bamboos are carbonized, so that the situation that alien insects stay on the surfaces of the bamboos is avoided, germs and eggs inside the bamboos can be killed completely with the high pressure at the high temperature, meanwhile, sugar, air, impurities and the like inside the bamboos can be extracted out under vacuum, nutriment needed by moths is removed, only wood fibers remain, bacterium regeneration is avoided, and damage to the bamboos by worms is not liable to occur.

Description

technical field [0001] The invention relates to an anti-corrosion and anti-mildew process for bamboo. Background technique [0002] Bamboo contains more hemicellulose, starch, sugar and protein than wood. Even if it is hot-pressed into bamboo-based panels such as automobile compartment floor, bamboo floor, bamboo recombined wood and other products, these bamboo-based panel products will be damaged during use. If it encounters the right temperature and temperature, it is prone to mildew and decay. Especially when these products are used outdoors, due to climate change, it is inevitable that there will be conditions where the temperature and humidity meet the growth of mold and decay bacteria. Early slight mildew appears on the surface of bamboo products, which only affects the appearance, but as the mold develops, mycelia will penetrate deep into the bamboo products, and decaying bacteria will also develop, which will change the microstructure of bamboo, which will not only ...

Problems solved by technology

Early slight mildew appears on the surface of bamboo products, which only affects the appearance, but as the mold develops, mycelia will penetrate deep into the bamboo products, and decaying bacteria will also develop, which will change the microstructure of bamboo, which will not only affect the appearance, It also greatly reduces the strength of bamboo products and reduces the service life of bamboo products

For bamboo, the effective anti-mold and anti-corrosion treatment is still chemical treatment, and most of them use organic solvent-based anti-mold and anti-corrosion agents, which have a great impact on the environment during construction and use.

At present, relevant domestic research institutions and production enterprises have realized the benefits of water-based anti-mildew preservatives, and developed several high-efficiency, low-toxic water-based bamboo wood protective agents, but they all use manual treatment methods such as soaking and brushing, and the treatment efficiency is low. Workers will be exposed to anti-mildew preservatives during operation, which will have a certain impact on personal health
