Description
Technical field
The present invention relates to the drying means technical field of wood single-plate, especially a kind of drying means of poplar veneer.
Background technique
In recent years, poplar wood is in Wood Flooring Industry using more and more extensive.Poplar wood is that a kind of speed of growth is exceedingly fast
Fast growing wood, 10-15 can become a useful person, but the poplar density of trees is low, and material is loose, using the dry poplar of conventional drying means
Veneer, poplar veneer are easily deformed in the drying process, cracking and shrinkage.Therefore using conventional drying means to poplar
Veneer is dried, and there are problems that poplar veneer is easily deformed, cracks and shrinkage.
Summary of the invention
The purpose of the present invention is the provision of a kind of drying means of poplar veneer.Using the dry poplar wood of the present invention
Veneer can solve and be easily deformed, crack and the problem of shrinkage in poplar veneer drying process.
Technical solution of the present invention: the drying means of poplar veneer includes the following steps,
A, poplar veneer is piled up in dry kiln；
B, it is 50-55 DEG C that dry kiln temperature, which is arranged, and it is 25%-30% that poplar veneer, which is dried to moisture content, obtains B product；
C, it is 40-50 DEG C that dry kiln temperature, which is arranged, and controlling humidity in dry kiln is 80%-90%, B product is dried to aqueous
Rate is 18%-20%, obtains C product；
D, it is 35-45 DEG C that dry kiln temperature, which is arranged, and controlling humidity in dry kiln is 70%-80%, C product is dried to aqueous
Rate is 13%-17%, obtains D product；
E, it is 30-40 DEG C that dry kiln temperature, which is arranged, and controlling humidity in dry kiln is 60%-70%, D product is dried to aqueous
Rate is 8%-10%, and kiln discharge obtains E product；
It F, is 25-30 DEG C in temperature by E product, humidity is to place 1-3 days to obtain finished product in 40%-50% environment.
In the drying means of poplar veneer above-mentioned, in step B, the heating rate of the dry kiln is 1-2 per hour
℃。
In the drying means of poplar veneer above-mentioned, in step B, it is 28% that poplar veneer, which is dried to moisture content,.
In the drying means of poplar veneer above-mentioned, in step C, the heating rate of the dry kiln is 1-2 per hour
℃。
In the drying means of poplar veneer above-mentioned, in step D, the heating rate of the dry kiln is 0.5- per hour
1℃。
In the drying means of poplar veneer above-mentioned, in step E, the heating rate of the dry kiln is 0.5- per hour
1℃。
Compared with the prior art, poplar veneer is first put into dry kiln by the present invention, in 50-55 DEG C of drying to aqueous
Rate is 25%-30%, is 40-50 DEG C then at temperature, and humidity is dried to moisture content under conditions of being 80%-90 be 18%-20%, then
It is 35-45 DEG C in temperature, humidity is dried to moisture content under conditions of being 70%-80% be 13%-17%, is 30-40 then at temperature
DEG C, moisture content is 8%-10% under conditions of humidity is 60%-70%, finally in temperature be 25-30 DEG C, humidity 40%-
In 50% environment, finished product is placed 1-3 days to obtain.The present invention uses low temperature drying when board using poplar board moisture content is larger, does not control wet
Degree, then gradually decreasing temperature and increasing humidity, is finally 25-30 DEG C in temperature, humidity is health in 40%-50% environment.The present invention can be kept away
The concentration for exempting from the drying stress and the mobile tension of moisture in poplar veneer drying process, it is dried to greatly reduce poplar veneer
It deforms, crack and the probability of shrinkage in journey, the present invention is reduced in conventional method ratio, the defect rate of deformation, cracking and shrinkage
8-12%.Using the dry poplar veneer of the present invention, it can solve and be easily deformed, crack and wrinkle in poplar veneer drying process
The problem of contracting.
