Description
Technical field
The invention mainly relates to woodwork processing technique field, more particularly to a kind of softening method of ash.
Background technology
Ash is that a kind of texture is straight, uniform, and property corrosion resistant, nail-holding ability is strong, the good wood material of stability, be fit to do furniture,
Floor, handicraft and other items, but be unlikely to deform, there is preferable durability, but ash material is harder, in processing
Difficulty is bigger, so craftsman first can bend timber when being processed to ash furniture item, to enter
Very long process could complete most basic moulding and design because the hardness of ash material is bigger, it on moulding not
Take advantage, production efficiency is slow, hence it is evident that improve the cost of ash furniture or handicraft.
The content of the invention
The defects of in order to make up prior art, it is an object of the invention to provide a kind of softening method of ash.
A kind of softening method of ash, comprises the following steps：
（1）Cutting：Ash section is cut according to required size, flitch can be made to carry out uniformly softening, be easy at softening
The progress of reason, obtains flitch；
（2）Immersion：Flitch is placed in the potassium sulfate solution that mass concentration is 1.3 ~ 1.5% and carries out immersion 10 ~ 12 hours, is accelerated
Potassium sulfate penetrates into flitch fiber, reduces the binding ability of lignin and cellulose, improves the flexibility of cellulose, be easy to be molded,
Take out, obtain immersion flitch；
（3）Cold-heat treatment：To immersion flitch even spraying castor oil, be placed in freezer and freeze 3 ~ 5 hours after spraying, take out after
60 ~ 65 DEG C are heated 4 ~ 6 hours, castor oil of spraying again, repeat spraying 3 times, are down to room temperature after heating naturally, increase ash fiber
Smoothness, it is easy to be molded, while the glossiness and antiseptic property of ash can be increased, improves the durability of ash product, obtain cold
It is heat-treated flitch；
（4）Dry：It is 63 ~ 65% that cold-heat treatment flitch, which is placed in 92 ~ 96 DEG C to be dried to water content, keeps the flexible of softening ash
Property and rigidity, to flitch uniform sprinkling, it is 20 ~ 25ml/m to spread water2, infiltrate 10 ~ 12 hours, be dried in 73 ~ 78 DEG C aqueous
Measure as 7 ~ 9%, enable flitch evenly drying, keep not getting damp again for ash, it is indeformable, increase the processing characteristics of ash, must soften
Ash.
The step（2）Immersion, temperature be 46 ~ 50 DEG C.
The step（3）Castor oil, each spray amount is 20 ~ 25ml/m2。
The step（3）Freezer, temperature be -43 ~ -41 DEG C.
The step（4）Infiltration, temperature be 36 ~ 38 DEG C.
The softening ash that the softening method of the ash is prepared.
The application method of the softening ash, before shaping, softening ash is placed in 70 ~ 80 DEG C and heated 30 ~ 40 minutes, is made soft
Change ash and recover flexibility, be down to room temperature after solid shape, continue to fix 5 ~ 6 hours, you can shaping.
It is an advantage of the invention that：The softening method of ash provided by the invention, method is simple, easy to operation, without large-scale
Equipment, increase ash pliability, lower molding difficulty；After ash section is cut by required size flitch can be carried out uniformly soft
Change, be easy to the progress of sofening treatment；First flitch is placed in the potassium sulfate solution of heat and soaked, accelerates potassium sulfate and penetrates into flitch
Fiber, reduce the binding ability of lignin and cellulose, improve the flexibility of cellulose, be easy to be molded；Will immersion flitch surface
Even spraying castor oil repeatedly, then freezing and heating is repeated, castor oil is penetrated into ash fiber, increase ash fiber is smooth
Property, it is easy to be molded, while the glossiness and Antimicrobial preservative performance of ash can be increased, improve the durability of ash product；It is cold and hot
First flitch is dried in short-term in lower temperature after processing, keeps the pliability and rigidity of softening ash, then sprays a small amount of water
Infiltrated, then reduce temperature and dried, enable flitch evenly drying, keep not getting damp again for ash, it is indeformable, increase Chinese scholartree
The processing characteristics of wood.
