Abstract
The invention discloses a process for preparing a pin board through cooperative treatment of pine fibers with laccase, xylanase and glucoamylase. Through the process, the use level of enzyme can be prominently reduced, and a fiber board with higher inner bonding strength can be obtained. The process comprises the following steps that the pine fibers are uniformly mixed with water and enzyme liquid in a container to adjust to a demanded pH value of 3.5-4.5; oxygen is introduced to generate a reaction by 50-70 min at a temperature of 28-30 DEG C; the pine fibers are taken out for drying; enzyme-treated fiber slurry is poured into a molding frame; moisture is filtered out; a slab is leveled under shaking by a liquid effect; and the dried fiber slab is cold pressed to extrude water, and is hot pressed.
Description
Technical field
The present invention relates to a kind of production technology of ferment treatment environmental protection deal board, belong to wood processing field.
Background technology
Along with the fast development of economic society, both at home and abroad to the demand of wildwood timber in increasing trend rapidly.In recent years, along with the raising of countries in the world environmental consciousness, retrenchment policy is carried out to timber export, further limit the outlet of natural timber, the nervous situation of timber demand is aggravated further.The substitute material of development wildwood timber, being the important channel alleviating the nervous contradiction of current wildwood timber supply and demand, is also the inevitable requirement of building a conservation-minded society.Fast-growing, high-yield woods is the forest tree resource that China enriches at present very much, China is successively proposed the large key project of forestry six from last century Mo, four are wherein had to be fast-growing and high-yield timber forest construction project, relate to 18 provinces in the whole nation, build nearly 4,000 ten thousand hectares of total scale, plan within about 2015, to set up nearly 600,000,000 mu of fast-growing and high-yield timber forest base.
On the cultural history of furniture, the Nordic intention of founder of pine furniture is performed meritorious deeds never to be obliterated, they turn the foul and rotten into the rare and ethereal, originally being become high-quality sheet material by the quick growing species of trees that excess resin is crowded through tread flaking oven dry, thus allow pine with its simple and unadorned texture, lifelike texture, pure beautiful color and luster, domestic environment is decorateeed plain, pure quiet, to incorporate and naturally harmonious and peaceful, thus humanity portion of pine furniture united state is decided to be environmental protection furniture.Pine furniture visually first " look " takes people by force.Indifferent to fame or gain soft pine true qualities " natural beauty difficulty is given up as hopeless " allow the low eyebrow of other seeds bow one's head.Not adding overwrought pine true qualities furniture is natural views, is nature landscape, the texture that essence is spacious, fine and smooth lines, hard and soft double Ji.Pine is a kind of confierophyte (common confierophyte has pine, China fir, cypress), it has rosin taste, look yellowish, furuncle scar is many, swell soon, easily to atmospheric temperature reaction, the extremely characteristic such as difficult natural air drying, therefore need through artificial treatment, as organic compound is removed in oven dry, degreasing, bleaching unified tree look, neutralization tree property, makes it not yielding.
" forest-science " 40 volume the 4th phase " enzyme activation treatment conditions and on pine cellulosic glue performance affect pre-test " is disclosed a kind of laccase treatment pinus khasys fiber and the method for pressboard, the sheet material internal bond strength that fiber after the internal bond strength of plate (or between slab bond strength) measurement result proof laccase treatment is pressed into can reach more than 1.0MPa, is significantly higher than water treatment fiber pressed sheet intensity.Enzyme liquid after inactivation and water equivalence, illustrate that other nutritional labeling in enzyme liquid and auxiliary agent can be ignored the contribution realizing timber Auto adhesion, to the mainly laccase itself realizing timber Auto adhesion and work.And the optimal parameter recorded is: enzyme dosage: 12-15U/g fiber; Concentration of substrate: 5%; PH value: 3.0 1 4.0; Enzymatic reaction temperature: (26 scholar 4) `C; Enzyme processing time: 2h; Hot pressing temperature: more than 140 DEG C.Adopt above-mentioned ferment treatment and sheeting process parameter, suppressed 300mmx300mmx8mm fiberboard, the density obtaining plate is 1.1575g/cm
3, internal bond strength measurement result is 1.536MPa.
The technique that the present invention aims to provide a kind of laccase, zytase, carbohydrase associated treatment pine cellulosic prepare deal board, described technique significantly can reduce the use amount of enzyme, and obtains the higher fiberboard of internal bond strength.
Summary of the invention
Based on the technical problem that background technology exists, the present invention is directed to background technology Problems existing, a kind of laccase, zytase, carbohydrase associated treatment pine cellulosic is provided to prepare the technique of deal board, described technique significantly can reduce the use amount of enzyme, and obtains the higher fiberboard of internal bond strength.
Object of the present invention is achieved through the following technical solutions:
A production method for ferment treatment environmental protection deal board, its step is as follows:
(1) raw material is prepared: prepare pine cellulosic;
(2) ferment treatment: pine cellulosic is mixed in a reservoir with water, enzyme liquid, the pH value being adjusted to requirement is 3.5-4.5, logical people's oxygen, and react 50-70min at 28-30 DEG C, taking-up drains;
(3) hot-forming: pour the fiber pulp after ferment treatment into shaping frame, moisture leaches, acting on to rock down and make slab smooth simultaneously by liquid, the fibre mat after draining first is colded pressing water squeezing, then hot pressing;
As preferably, the design parameter of described ferment treatment is: laccase dosage: 5-6U/g fiber, zytase dosage: 0.5-0.8U/g fiber, carbohydrase dosage: 1-1.5U/g, fibrous substrates concentration: 5%;
As preferably, described hot pressing temperature: 120-150 DEG C;
As preferably, described pressed fiber board 400mmx400mmx9mm.
It has been generally acknowledged that, the effect of laccase and lignin has two kinds of possible results.One is that lignin is farthest degraded, this application prospect mainly association with pulp bleaching possible on the one hand, papermaking wastewater process; Another kind is that the phenol of lignin is oxidized to after phenol oxygen-cent red radical through base and generates polymer, and possible application prospect is the chemistry one enzyme initiator system realizing timber Auto adhesion and the copolymerization of exploitation lignin one unsaturated monomer.In a word, laccase can increase fiber finer cell wall Auto adhesion power.The present invention surprisingly finds, laccase, zytase, carbohydrase can associated treatment pine cellulosic, and better effects if, consumption is more economized, and cost is lower, and this is great discovery of the present invention.
Usefulness of the present invention is:
1. present invention process environmental protection, does not contain hazardous substance;
2. the deal board bond strength for preparing of the present invention is high;
3. the present invention carries out coordinative role by several enzyme, significantly reduces consumption and the cost of enzyme.
