Abstract
The invention discloses a method for performing mouldproof and mothproof treatment to bamboo. The method includes the steps of firstly, soaking the bamboo in acid solution at 20-60 DEG C for 7-9 days, and taking out the bamboo to obtain acid-soaked bamboo; secondly, carbonizing the acid-soaked bamboo in superheated steam of 110-130 DEG C for 1-3 hours to obtain carbonized bamboo; and thirdly, using desiccation to lower water content of the carbonized bamboo to 6%-12% to obtain the mouldproof and mothproof bamboo. The method is simple in process, fine in controllability, low in cost, easy to industrialize, and needs no expensive equipment.
Description
Technical field
What the present invention relates to is a kind of processing method of bamboo wood mildew and insect proof.
Background technology
Bamboo has that growth is fast, output high, and once after afforestation as long as manage rationally, can continuous utilization; The purposes of bamboo is very extensive, except being processed into food, handicraft, more can be used for the every field such as building, material, chemical industry.As construction timber, every 60 bamboos just can replace a balk.Bamboo product (especially bamboo craftwork product) is more and more subject to people and likes in daily life, and bamboo furniture also comes into vogue gradually.
But no matter bamboo wood is as construction material or furniture, artwork, all exist three natural defects: easy infested mildew, cracking, distortion, in course of industrialization, there is again the environmental problem same with timber industry: abuse coating, adhesive, anticorrisive agent, processing waste is many, artificial like this cost increase causes that inter-industry competition is poor, market is imperfect, so that bamboo industry can not really become the industry of complete sustainable development.
For merits and demerits more than bamboo industry, from the angle of sustainable development, design bamboo wood mildew and insect proof treatment process, through long-term research and experiment, obtains a kind of processing method of bamboo wood mildew and insect proof.
Summary of the invention
Technical problem to be solved by this invention is to be to provide a kind of technique simple, and controllability is good, and cost is low, does not need expensive equipment, is easy to the processing method of the bamboo wood mildew and insect proof of industrialization.
In order to solve the problems of the technologies described above, the processing method of bamboo wood mildew and insect proof provided by the invention, procedure of processing comprises:
(1), bamboo wood is immersed in acid solution, soaking technology is volume ratio=1 of 20-60 ℃ of temperature, bamboo wood and acid solution: (0.5-2.0), 7-9 days, then takes out bamboo wood, obtains acid bubble bamboo; Wherein acid solution be by formic acid, acetic anhydride, maleic anhydride, folium eucalypti acid according to mass percent concentration (0.1-0.2%): (0.2-0.4%): (0.1-0.15%): (0.3-0.5%) mix.
(2), acid steeped to bamboo in 110-130 ℃ of water vapour, carry out charing 1-3 hour, medium is superheated vapour, obtains charing bamboo.
(3), then adopt seasoning that charing bamboo moisture content is dropped to 6%-12%, obtain mildew and insect proof bamboo wood; As long as wherein seasoning refers to that all drying means that can make bamboo moisture content drop to 6%-12% all can.
Adopt the processing method of the bamboo wood mildew and insect proof of technique scheme, the mildew and insect proof bamboo wood of processing, mechanical strength declines in 9%, has the effects such as mildew-resistant, insect protected.Technique of the present invention is simple, and controllability is good, and cost is low, does not also need expensive equipment, is easy to industrialization, and prospect is widely used.
In sum, it is simple that the present invention is to provide a kind of technique, and controllability is good, and cost is low, do not need expensive equipment, is easy to the processing method of the bamboo wood mildew and insect proof of industrialization.
