Abstract
A method for treating wood in order to prevent cracking and deforming includes such steps as sawing, and steaming in a steaming room for 48-72 hr while gradiently controlling the heat-supplying pressure to be 3-5 Kg/sq.cm.
Description
Technical field
The present invention relates to a kind of processing method of timber, relate in particular to a kind of boiling processing method timber.
Background technology
Less to the method for the employing of the processing before the timber stoving at present, the processing to the famous and precious hardwood of import also is at the early-stage especially.At present domesticly treating of wood generally is simple oven dry handles, adopt this simple oven dry to handle, timber (hardwood class) easily produces crack and distortion after making finished product, thereby makes the leftover problem of timber after making finished product more.
Therefore having the researcher to propose to adopt boiling technology to handle timber (only is imagination, have not yet to see open report), through test, the digestion time of discovery timber be can not determine, in case digestion time is long or too short, will make the timber after the boiling gloomy, irregular colour is even, oven dry back cracking and crooked situation are more serious, and volume recovery is undesirable.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of quality height for the defective that overcomes above-mentioned prior art existence, and the natural characteristic of sheet material is the processing method of natural and bright and new timber more.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of processing method of timber is characterized in that, this method may further comprise the steps: after timber is processed sawing, put into vaporium, adopt steam to carry out boiling as thermal source, and control heat supply pressure, this heat supply pressure is controlled at 3kg/cm
2～5kg/cm
2, in conjunction with indoor temperature and humidity, carried out boiling 48～72 hours, promptly finish processing.
In 36 hours, put into vaporium after the described timber processing sawing and carry out the boiling processing.
Described timber adopts different stacking methods, and controls the relation of timber amount of storage and vaporium internal volume according to the thickness difference of its processing after sawing, and it is remained between 60%～80%.
Described stewing temperature is controlled between 60 ℃～70 ℃, and humidity is controlled between 80%～100%.
Compared with prior art, the present invention adopts steam to carry out boiling as thermal source, and control heat supply pressure, carrying out echelon handles quality (cracking, distortion, the implosion etc.) situation of the timber (particularly black walnut) obtain and takes a favorable turn, and the natural characteristic of sheet material is nature and bright and new more, and the excellent rate of finished product improves 20%～30%.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
Embodiment 1
A kind of black walnut hardwood, the sheet material moisture content about 85% when advancing kiln, and to control this black walnut hardwood amount of storage be 70% of vaporium internal volume, adopts steam as thermal source, through 4kg/cm
2Uniform pressure is handled, and temperature is controlled at 65 ℃, humidity and is controlled at 80%, boiling after 65 hours timber stoving all right.
Embodiment 2
A kind of black walnut hardwood, the sheet material moisture content about 70% when advancing kiln, and to control this black walnut hardwood amount of storage be 60% of vaporium internal volume, adopts steam as thermal source, through 3kg/cm
2Uniform pressure is handled, and temperature is controlled at 70 ℃, humidity and is controlled at 90%, boiling after 72 hours timber stoving all right.
Embodiment 3
A kind of black walnut hardwood, the sheet material moisture content about 70% when advancing kiln, and to control this black walnut hardwood amount of storage be 80% of vaporium internal volume, adopts steam as thermal source, through 5kg/cm
2Uniform pressure is handled, and temperature is controlled at 60 ℃, humidity and is controlled at 100%, boiling after 48 hours timber stoving all right.
Claims (3)
