Abstract
The present invention relates to a method for the denaturing processing of a pencil board. The main working procedures comprise pencil board preparation, preheating, evacuation, impregnation (using a softener and a cross-linking agent), cooking, dyeing and waxing. The present invention can replace the board baking method. The present invention not only can be used for processing basswood and alniphyllum fortunei to increase the quality of the board and the utilization rate of wood, but also can be used for processing wood not used for making pencils, such as pine, rubber wood and Italian poplar, so as to meet the requirements for making the pencils; thus, the wood sources for making the pencils are expanded.
Description
The present invention relates to a kind of method for processing pencil board in modifying.Pencil plate chemical tendering is handled, and is understood by people, has all done many research work both at home and abroad in this respect, roughly can reduce two classes.
Method of chemical treatment.The chemical agent that it comprises organic acid or inorganic acid, alkali or some salt such as nitrate and contains at least a metal erosion retardant acts on timber, softening under suitable condition the processing washed chemical agent off with the solvent that is fit to then with reaction product.The drying of wood, again the timber of drying is handled with the processing agent solution, its inorganic agent has animal fat, fatty acid salt, oil or paraffin etc. again.
Fused agent method, United States Patent (USP) 2907684 etc. are C with polyethylene glycol, paraffin etc. or with carbon number
8～C
50, fusing point is lower than 180 ℃, preferably uses chemical substances such as paraffin, Fluhyzon, chlorinated paraffin wax, tar, anthracene, bitumen blowing thing and nonionic surface active agent, in uniform temperature, handle under the pressure, change the mechanical property of timber, to reach needed softening purpose.
In the said method; the former is owing to adopt strong chemical agent; must add the metal erosion retardant; with protection equipment; used chemical agent is after effect stops; need clean in the lump together with its reaction biology; drying repeated treatments such as wax again; thereby cause irrational energy consumption; though the latter's processing method has the color and luster that improves timber; reduce advantages such as hygroscopicity, but can not make the cutting resistance of timber obtain basic change, do not reach the prices of raw and semifnished materials costliness of pencil with material requirement and use.For this reason, the pencil industry still generally adopts traditional handicraft-method for baking wooden board at present.Method for baking wooden board has the board size good stability that reduced investment, equipment are simple, with low cost, baked, and hygroscopicity is low, can satisfy the processing of the high-quality pencil of linden and so on material.Yet it also exists unsurmountable disadvantage; At first method for baking wooden board lacks the science operating basis, and entirely with workman's knowhow, the plank mass discrepancy after baking is big, and the plate aberration has defectives such as more serious burnt limit, fillet.Secondly, be not suitable for opening up the processing of non-pencil with material, this is to timber resources today in short supply, and it can not satisfy the production needs.
Application of the present invention can substitute the roasted method of pencil plate.Both be applicable to high-quality timber, also be suitable for substituting timber, and, can improve the quality and the class of making pen of plate, improved timber utilization rate now using the processing of timber one linden, Alniphyllum fortunei wood.In addition, adopt this method, help opening up the new assortment of a system usefulness,, after chemical tendering is handled, also can become the raw material of system pencil as pine, rubber trees, Italian poplar wood etc.
The present invention utilizes chemical softener, under certain condition, destroys wood cell and constitutes the molecular structure of cellulose, hemicellulose and lignin that its cell forms, thereby reduce the machinery-physical property of timber.The pencil plate of handling through this method has following characteristics: good processing and manufacturing performance is arranged, and the pencil of making has good volume and cuts performance; Plate matter is soft, the plate face is smooth; The clear no fillet phenomenon of frid corner angle; Bright and clean no rat of penholder and bar hair; Become a color and luster even.
Institute of the present invention with medicament is easy to get, and corrosivity is low, and is nontoxic.Technology is simple, flow process is short, equipment is few, " three wastes " but the comprehensive regulation, softening plate cost is low.
Basic point of the present invention: be processed as 180 * (40-80) * 5mm pencil plate, through giving heat to 100-110 ℃, found time 10-20 minute, implantation concentration is the softening agent of 0.1-10%, be: ammonium sulfite or ammonium bisulfite, or the mixture of the two, ammonification be the pH conditioning agent, regulator solution pH is 4-10, and add the 0.2-0.5% crosslinking agent, it is formaldehyde or trichloroacetaldehyde or urea.In negative pressure or add and depressed dipping 1-5 hour, be preferably 1-1.5 hour, plank is extracted softening agent out after fully soaking into, steam with water vapour and separate, steam pressure (2-10) * 9.80665 * 10
4Pa is preferably (2-6) * 9.80665 * 10
4Pa, 119.6 ℃-179 ℃ of temperature, best 119.6-158.1 ℃, time 30-120 minute, preferably 60-90 minute, venting was carried out finding time the second time more then, the acid orange IG-100% of implantation concentration 0.1-0.3% or acid scarlet or the two mixed liquor, and in (6-10) * 9.80665 * 10
4Under the Pa pressure, pressurizeed 60-120 minute, thereafter plank is heated to more than 140 ℃ once more, but should not surpasses 150 ℃, venting after 20-60 minute, inject modifier thereupon, it is the mixed liquor of the water of paraffin and the nonionic surface active agent that contains 0.1-0.5%, inhales wax through 20-30 minute and handles, after control suction wax amount reaches 2-3 kilogram/ten thousand pen, extract solution out, plank is sent to dry getting final product.The present invention can not only handle Alniphyllum fortunei wood, and can handle pine, rubber trees and willow wood.
