Description

A kind of aging wooden products processing method
Technical field
The invention belongs to treating of wood field, be specifically related to a kind of aging wooden products processing method.
Background technology
Now with the raising of people's living standard, people are also improving for the pursuit of art, in the fields such as furniture, The most a lot of people pursue pseudo-classic furniture, before prepared by pseudo-classic furniture, need to make plank old process, and present plank does old many Use strong acid, highly basic to corrode, but it is more apparent to do old vestige, also has the strongest corrosivity to plank, causes furniture to make Shorten with the time, and along with using the change of furniture color to cause quality to decline.People attempt using the more gentle of other Solution carries out doing old process, but majority also exists complicated component, preparation trouble, processes time length, inconvenient problem with use.This Outward, existing do the woodwork that aging method prepares and also exist the surface moisture absorption short-tempered, easy, the problem such as the most wear-resisting more.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of aging wooden products processing method.
The present invention is achieved through the following technical solutions:
A kind of aging wooden products processing method, comprises the steps:
(1) woodwork pretreatment:
A. the ratio of wormcast and water 1:4 by weight is mixed, then stir with the rotating speed of 600 ~ 700 revs/min Mix, cross leaching supernatant after 30min standby;
B. being immersed in by pending woodwork in the supernatant of operation a gained, heating keeps the temperature of supernatant to be 40 ~ 50 DEG C, standing processes and is taken out by woodwork after 1h, with clear water rinse one time standby;
C. the woodwork after rinsing operation b dries process, when the water content on its surface is 55 ~ 60%, puts it into temperature Degree, for storing 15min in the freezer of-6 ~-4 DEG C, is immediately placed in after taking-up in drying kiln, treats that the ice crystal of wood product surface steams completely Take out after Faing;
(2) old process is done:
Weigh following material the most by weight: 3 parts of Pericarpium Citri junoriss, 2 parts of Ramulus Moris, 1 part of sodium carboxymethyl cellulose, 1.5 parts of sodium pyrosulfates, 0.6 part of ammonium chloride, 1 part of polyvinyl alcohol, 180 parts of water;
B. Pericarpium Citri junoris and Ramulus Mori being pulverized 100 mesh jointly, then the deionized water with its gross mass 3 times mixes jointly, heating boiling After boiling 25min, filter to extract filtrate standby;
C. by sodium carboxymethyl cellulose, sodium pyrosulfate, ammonium chloride, polyvinyl alcohol is common with water mix homogeneously after, then will operation b institute The extraction filtrate obtained adds, and is again stirring for uniformly, and the pH value regulating solution overall is 5.6 ~ 6.2, must do old liquid standby;
What d. step (1) pretreated woodwork be immersed in operation c gained does in old liquid, simultaneously applies in old liquid to hand over to doing Stream electricity, takes out woodwork, with standby after deionized water rinsing after being jointly processed by 3 ~ 4h;
(3) process of guaranteeing the quality is dried:
A. the woodwork after step (2) being processed is put into and is dried process in calorstat, be dried to woodwork water content be 12 ~ 15% is standby;
B. the woodwork after being processed by operation a places in alternating temperature case, and the highest temperature controlling alternating temperature case is 42 ~ 45 DEG C, lowest temperature Being 2 ~ 5 DEG C, relative humidity remains at less than 15%, and period carries out continuous alternating temperature operation with the speed of 4 DEG C per minute, i.e. arrives Lower the temperature when reaching the highest temperature, heat up when arriving lowest temperature, after processing 30 ~ 40min, take out.
Further, described in step (1) operation c, the temperature in drying kiln is 130 ~ 140 DEG C.
Further, described in step (2) operation d, the frequency of alternating current is 50 ~ 55Hz, and the electric current density of alternating current is 90 ~100A/m2
Further, described in step (3) operation a, the temperature in calorstat is 55 ~ 60 DEG C.
There is advantages that
(1) first the present invention has carried out pretreatment to woodwork, and enzyme in wormcast and microorganism are by the fiber of wood product surface Carry out softening, loose, then put it into and under low temperature environment, carry out surface crystallization, finally toast with high temperature, can well go Except surface fiber so that wood product surface is the most smooth, compact, follow-up process operation.
(2) it is simple that what the present invention prepared does old liquid composition, safe and nontoxic, noresidue, and solution is overall in subacidity, improves Strong acid easily causes the etching obvious problem of phenomenon, and under the effect of alternating current, it does old speed and is greatly improved with effect, Alternating current has a characteristic of sense of current mechanical periodicity simultaneously, drives charged particle to move back and forth, and polyvinyl alcohol etc. is effectively Composition preferably wraps the surface at woodwork.
(3) to do old after woodwork carry out drying and guarantee the quality process, can further improve and do old effect, strengthen its heatproof Change, crack resistence, the ability of anti-moisture absorption.
(4) the inventive method overall simple, treatment effeciency is high, can complete to do old process, compare traditional lacking in one day Then one week, the processing mode of month was compared at most, greatly improves work efficiency, reduced cost of manufacture, and do old after Wood product surface is the most smooth, compact, and humidity resistance is more preferable, and water absorption rate reduces about 15%, and cracking rate during use reduces About 20%, the life expectancy of woodwork extends more than 10%, and use value is higher.
