Description
Technical field
The invention belongs to treating of wood fields, and in particular to a kind of aging wooden products processing method.
Background technology
Now with the improvement of people's living standards, people are also improving the pursuit of art, in the fields such as furniture,
Many people pursue pseudo-classic furniture now, before pseudo-classic furniture preparation, need to carry out doing old processing to plank, present plank does old more
Corroded using strong acid, highly basic, but it is more apparent to do old trace, also has very strong corrosivity to plank, furniture is caused to make
Shortened with the time, and with using furniture color change to cause quality decline.People attempt using other more mild
Solution carries out doing old processing, but there is complicated component, preparation trouble, processing time length, inconvenient problems with use for majority.This
Outside, it is existing do woodwork made from aging method mostly there is surfaces short-tempered, the easy moisture absorption, it is not wear-resisting the problems such as.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of aging wooden products processing methods.
The present invention is achieved through the following technical solutions：
A kind of aging wooden products processing method, includes the following steps：
（1）Woodwork pre-processes：
A. by wormcast and water by weight 1:4 ratio is mixed, then with 600 ~ 700 revs/min of rotating speed into
Row stirs, and it is spare to filter to take supernatant after 30min；
B. by pending woodwork be immersed in operation a obtained by supernatant in, heating keep supernatant temperature be 40 ~
50 DEG C, woodwork is taken out after stewing process 1h, with clear water rinse one time it is spare；
C. the woodwork after being rinsed to operation b carries out drying processing, when the water content on its surface is 55 ~ 60%, is put
Enter in the freezer that temperature is -6 ~ -4 DEG C and store 15min, is immediately placed in drying kiln after taking-up, waits for that the ice crystal of wood product surface is complete
It is taken out after pervaporation；
（2）Do old processing：
A. following substance is weighed by weight：3 parts of orange peels, 2 parts of ramulus moris, 1 part of sodium carboxymethylcellulose, 1.5 parts of pyrosulfuric acids
Sodium, 0.6 part of ammonium chloride, 1 part of polyvinyl alcohol, 180 parts of water；
B. orange peel and ramulus mori be crushed into 100 mesh jointly, then mixes, adds jointly with the deionized water of 3 times of its gross mass
After 25min is boiled in heat boiling, filter to extract filtrate spare；
It c. jointly after mixing by sodium carboxymethylcellulose, sodium pyrosulfate, ammonium chloride, polyvinyl alcohol and water, then will behaviour
Make the extraction filtrate obtained by b to be added, be again stirring for uniformly, and the pH value for adjusting solution entirety is 5.6 ~ 6.2, and it is standby must to do old liquid
With；
D. by step（1）Pretreated woodwork is immersed in doing in old liquid obtained by operation c, while being applied to doing in old liquid
Add alternating current, takes out woodwork after being jointly processed by 3 ~ 4h, it is spare after being rinsed with deionized water；
（3）Dry processing of guaranteeing the quality：
A. by step（2）Treated, and woodwork is put into insulating box that processing is dried, dry to woodwork water content
It is spare for 12 ~ 15%；
B. will operation a treated that woodwork places into becomes in incubator, control become the highest temperature of incubator into 42 ~ 45 DEG C, most
Low temperature is 2 ~ 5 DEG C, relative humidity remain at 15% hereinafter, period continuous alternating temperature operation is carried out with 4 DEG C of rate per minute,
Cool down when reaching the highest temperature, heats up when reaching lowest temperature, after handling 30 ~ 40min, taking-up.
Further, step（1）It is 130 ~ 140 DEG C to operate the temperature in drying kiln described in c.
Further, step（2）The frequency for operating alternating current described in d is 50 ~ 55Hz, and the current density of alternating current is 90
~100A/m2。
Further, step（3）It is 55 ~ 60 DEG C to operate the temperature in insulating box described in a.
The present invention has the advantages that：
（1）The present invention first pre-processes woodwork, and the enzyme and microorganism in wormcast are by wood product surface
Fiber is softened, loosely, then is put it into and carried out surface crystallization under low temperature environment, is finally toasted with high temperature, can be very well
Removal surface fiber so that wood product surface is more smooth, compacts, be conducive to subsequent processing operation.
（2）What the present invention prepared do, and old liquid ingredient is simple, safe and nontoxic, noresidue, and solution is in integrally subacidity, is improved
Strong acid easily causes the apparent problem of etching phenomenon and under the action of alternating current does old rate and be greatly improved with effect,
Alternating current has the characteristic of current direction mechanical periodicity simultaneously, and charged particle is driven to move back and forth, and polyvinyl alcohol etc. is effective
Ingredient preferably wraps on the surface of woodwork.
（3）To do it is old after woodwork carry out drying and guarantee the quality processing, can further improve and do old effect, enhance its heatproof
Change, crack resistence, anti-moisture absorption ability.
（4）The method of the present invention overall simple, treatment effeciency is high, can be completed in one day and does old processing, lacks compared to traditional
Then one week, at most one month processing mode was compared, and working efficiency is greatly improved, and is reduced the production cost, and do it is old after
Wood product surface is more smooth, compacts, and humidity resistance is more preferable, and water absorption rate reduces 15% or so, and cracking rate when use reduces
20% or so, the life expectancy of woodwork extends 10% or more, and use value is higher.
