Description
Technical field
The invention belongs to timber bating effect quantitatively regulating and controlling technical field, and in particular to a kind of hydro-thermal-microwave combined softening
The model building method of timber bating effect after processing.
Background technology
Either to timber carry out transverse compression with improve its density still it is carried out longitudinal compression make its produce gauffer
To improve its transverse curvature, softening process is all very important a link.Softening for timber, the method handled at present
Mainly there is Physical（Such as：Boiling, decatize, microwave, high-frequency dielectric heat）And chemical method（Such as：Liquefied ammonia, gaseous ammonia, ammonium hydroxide,
Hydrazine, urea and alkali process etc.）Two classes（Song Kuiyan, 2006）.Under normal conditions, timber is on the premise of without softening,
It is essentially in glassy state.Be compressed to ensure timber under conditions of big micro-damage does not occur it is closely knit, one
As need in advance to soften timber；On the contrary, can be without the intercellular layer of the timber softened in advance its cell when compressed
Tear, which produces, under the action of external force destroys and causes being greatly reduced for strength of wood.The reason for timber can be softened be its mainly into
Lignin, cellulose and hemicellulose is divided to be respectively provided with glass transition temperature, as long as giving certain moisture and temperature conditionss, three
The glass transition temperature of big element will reduce, so as to achieve the purpose that softening.Research confirms that as long as temperature is no more than 160 DEG C of wood
Three big elements of material would not degrade（Guo Menglin etc., 2010）, its mechanical strength remains to recover as before after moisture loses.It is but different
For seeds due to its cell membrane chemical constituent and the difference of structure, soft condition is also different, i.e., one kind in one experiment
Timber corresponds to a specific sofening treatment technique, and the process conditions by testing certain timber obtained softening are possible cannot
It is useful in the softening of other timber.Under normal conditions, the height of density has direct influence to the bating effect of timber.Density
Low timber, the amount of wood cell wall material is just few in unit volume（I.e.：The absolute content of three big elements is got in unit volume
It is low）, soften and easily carry out；On the contrary, softening is not easy to carry out, when softening, just needs the process conditions of higher（Such as：Higher temperature
Or longer time）It has been only possible to preferable bating effect.If we can build the amount of wood cell wall material（Density）, it is soft
Change the relation of process conditions and timber bating effect, can solve " in an experiment a kind of timber only correspond to one it is specific
The problem of sofening treatment technique ".So amount to wood cell wall material（Density）, softening process condition and timber softening imitate
The structure of fruit relation（I.e.：The a set of softening process suitable for all timber of optimization）This will be the core of the invention for needing to solve
Problem.

Row significance test, first to axial maximum compression ratey 1 Multiple regression equation fitting effect evaluated, ensure 5 factors and
Constant is notable to the regression coefficient of axial maximum compression rate；Then to horizontal maximum compression ratey 2 Multiple regression equation fitting
Effect is evaluated, and ensures that 5 factors and constant are notable to the regression coefficient of horizontal maximum compression rate.
10. the quantitatively regulating and controlling method of timber bating effect after hydro-thermal according to claim 1-microwave combined sofening treatment,
It is characterized in that multiple regression equation described in the step C timber bating effect after hydro-thermal-microwave combined sofening treatment is determined
Application in amount regulation and control, the application are specially to take timber to be softened, and are givenx 1 ,x 2 ,x 3 ,x 4 ,x 5 Parameter value, substitute into it is polynary
Regression equation, you can obtain the maximum compression rate of timber to be softenedy 1 With horizontal maximum compression ratey 2 Model value；Or give and treat
Soften the maximum compression rate of timbery 1 With horizontal maximum compression ratey 2 Model value, you can extrapolate its hydro-thermal-microwave combined softening
The process conditions of processing；So as to fulfill the quantitatively regulating and controlling of timber bating effect.
