Description
Technical field
The invention belongs to wood mould technical fields, are related to a kind of green of water vapour boiling and carbon dioxide extraction timber
Mildew-proof treatment method.
Background technology
It is well known that the timber such as rubber wood timber, sweetgum wood, pine due to its own there are the internal organizational structure of the easy moisture absorption or
Richness closes nutriment and volatile organism, causes it easily to go mouldy in wet environment and discoloration, it is sharp to influence following process
With.If rubber wood timber belongs to diffuse porous wood, drying shrinkage is small, easy processing, cheap, be make the high-quality timber of furniture and toy, but by
Contain the nutriments such as about 1% protein and 3% starch in it, easily goes mouldy in wet environment.
CN102265902A discloses " a kind of mould inhibitor of rubber wood timber and its application " patented technology, be first use alkylnaphthalene acid sodium solution into
Row pretreatment, then carries out mould proof processing using the mould inhibitor being made of 10% sulfuric acid, N-Ethylbutylamine, sodium tetraborate decahydrate.
CN103707375A discloses " a kind of processing method that solid wood is mould proof ", is sprayed using solid wood drying, constant temperature, dehumidifier, surface second
Four steps that varnish with lacquer carry out mould proof processing to solid wood, and the difference that the drying of patent solid wood is dried with common wood is to use steam pair
Drying shed is timed temperature adjustment and conditioning, and maximum temperature rises to 85 DEG C, bad to solid wood anti-mold effect；Constant temperature and dehumidifier
Step is primarily to control the moisture content of solid wood；Surface second spraying japanning belongs to the subsequent processing operations of solid wood, as reality
The wooden pretreatment process will influence solid wood subsequent use.It is mould proof to be applied to the early stages such as the boron phenol mixture of wood preservation in the prior art
, all there is certain toxicity, generated to human body in agent, low-toxicity industrial bactericide, the efficient organic chemical reagent mould inhibitor of low toxicity
Harm, hypotoxicity mould inhibitor can not meet the requirement safe and harmless to timber such as wooden toy industry.Solid wood drying and surface
The purposes for spraying the Combined Treatments such as japanning limitation timber, makes troubles to timber subsequent applications.
Invention content
The technical problem to be solved by the present invention is to develop a kind of to utilize the Nantural non-toxics such as saturated vapor and carbon dioxide
Medium reacts with the building stone of the easy moisture absorption in timber, removes most of nutriment and volatile organism, long-term anti-corrosion effect
The good timber green mould proof processing method of fruit.
Technical solution is used by solving above-mentioned technical problem：Timber, which synchronizes, carries out saturated vapor boiling and titanium dioxide
Carbon-impregnated proposes processing, and timber is under high temperature high temperature, saturated vapor and the common atmosphere of carbon dioxide, since chemical group combines, wood
Material ingredient such as is thermally decomposed at the chemical reactions, reduces in timber the easily building stone of the moisture absorption；Saturated vapor and carbon dioxide are being located
It is flowed in reason tank, takes away the nutriments such as Partial Protein and lipid and volatile organism；Carbon dioxide is dissolved in water and generates centainly
The carbonic acid of amount plays the role of acidleach to timber and carries.
The mildew-proof treatment method carries out as follows：
One, using water vapour as heat medium, carbon dioxide gas, exclusion processing are passed through from another air inlet pipe by compressor
Air content is rapidly heated within 5% to 100-120 DEG C in tank, and processing pressure tank keeps 0.5-1MPa, soaking time 2-
4h；
Two, continue to be passed through water vapour, air compressor machine pressurization is passed through carbon dioxide, handles pressure tank 1-3MPa, be warming up to 120-
150 DEG C, soaking time 4-8h；
Three, continue to be passed through water vapour and carbon dioxide, keep the temperature 120-150 DEG C, handle pressure tank 1-2MPa, it is dry to aqueous
Within rate 5%；
Four, stop being passed through carbon dioxide, spraying cooling adjusts humidity, Temperature fall, moisture content 4- within 90 DEG C
8%.
Timber is the plank of domestic the tradition high-quality timber and fast growing wood such as maple, rubber wood timber, pine, plate thickness less than etc.
In 100mm.
The beneficial effects of the invention are as follows：This method is synchronized using timber carries out saturated vapor boiling and carbon dioxide extraction
Processing reduces the building stone of the easy moisture absorption in timber, removes the nutriments such as Partial Protein and lipid and volatile organism,
Environmentally protective, safe and harmless, long-term anti-mold effect is good；With the timber Environmental Safety of the mould proof processing of this method, can be used for preparing
Virgin wooden toy, baby child's daily necessities etc..
