Description
Technical field
The invention belongs to wood processing treatment technical fields, and in particular to a kind of timber anticracking processing method.
Background technique
With the continuous improvement of living standards, people require also to step up to the class of furniture, and wherein wood furniture is outstanding
It is well received by consumers.With the progress of science and technology, the connection between all parts of the world is more and more closer, the wood furniture that is produced from the country
Fast-selling all parts of the world, while also technical problem is brought to wood furniture industry: due to the temperature difference of different regions on the earth
Greatly, humidity is different, and the framing timbers of wood furniture are very easy to cracking and deformation, so that the condition of wood furniture is destroyed,
Great puzzlement is brought to wood furniture business and consumer.
Currently, in order to reduce the cracking of wooden product and deformation, it is common practice to paint on wooden product surface, be reduced with this
Influence of the extraneous humidity to wooden product, but wooden deep layer can not be handled due to doing paint, user locates after a period of use
Reason layer will be ground off, in addition, making paint and can change the natural colored of timber itself, wooden comb be made to lack natural color,
In addition painting the influence due to itself particle, and the self inflation of itself is painted, do paint on wooden product surface or cannot subtracted very well
Influence of few extraneous humidity to wooden product.On the other hand, one mainly is formed in wood surface when traditional paint uses outdoors
The layer very strong paint film of physicochemical property is closed in timber surface layer, prevents timber from breathing, easy to crack over time, paint film is easy to fall off；
When being irradiated by sunlight and ultraviolet light, xanthochromia is easily generated, weatherability, durability are poor；Meanwhile traditional paint coating former material
Material is mostly that chemical product is done harm to huamn body containing a large amount of toxicity and stimulating component, has been unable to meet people instantly
Requirement for health environment-friendly.Therefore, it is badly in need of wanting a kind of healthy, green, the method that can effectively prevent timber crack at present
To prevent timber crack.
