Description
Technical field
The present invention relates to pulp technology for making paper, particularly relate to a kind of make paper grade pulp by raw material activity legal system of fresh bamboo
Technique.
Background technique
China's bamboo resource is abundant, and the annual output of bamboo occupies the first in the world, and most of bamboo pulping Papermaking Performances are excellent,
Close to broadleaf.However bamboo class raw tissue close structure, medicinal liquid osmosis is difficult, in traditional bamboo digesting technoloy, pulp washing
Black liquor directly send evaporation, is easy to happen silicon obstacle and calcium fouling, there are complex operation, digester cycle is long, production efficiency is low,
It consumes energy the problems such as serious, seriously polluted, does not meet green, environmental protection, low-carbon, energy-efficient production theory that country advocates.Thus state
The interior production to bamboo pulp has carried out maximum limitation, how to improve existing bamboo pulp manufacturing technique, is ensuring compliance with country
While green, environmental protection, low-carbon, production energy-saving theory, bamboo resource is efficiently used, to meet worldwide paper requirements not
Break widened requirement, is the current technical issues that need to address.
Summary of the invention
To solve the above the deficiencies in the prior art, the invention proposes one kind to make paper grade (stock) by raw material activity legal system of fresh bamboo
The technique of paper pulp.
The technical scheme of the present invention is realized as follows:
A kind of technique for making paper grade (stock) bamboo pulp using fresh bamboo as raw material activity legal system, includes the following steps:
(1) it cuts bamboo: bamboo section will be obtained after the cleaning of fresh bamboo wood, cutting；
(2) fragment: bamboo section is subjected to fragment and obtains bamboo chip；
(3) super-pressure classification rolls: bamboo chip being placed in classification in roll rolling and is rolled, classification is rolled grinds including four to six grades
Pressure, grinding pressure at different levels are gradually increased；Classification rolls so that fiber stress is gradually increased, and fiber is avoided to deform because once suppressing
Cause fibrous fracture greatly, the integrality of fiber can be kept to greatest extent；Rolling can be by the wood between fiber also in liquid
Element, protein, amino acid and various flavones etc. first squeeze out most of；
(4) thread rolling: the bamboo fiber bundle that super-pressure classification rolls being placed in thread rolling machine and carries out thread rolling, thread rolling process
In can squeeze out again between fiber also in the lignin of liquid, protein, amino acid and various flavones etc.；
(5) primary filtering squeezes: the bamboo pulp containing a large amount of fibers after thread rolling first being carried out physical filtering and squeezes to obtain again
Initial filter bamboo pulp；
(6) secondary filter squeezes: sequentially carrying out physical filtering and two into initial filter bamboo pulp plus after water after heating stirring again
Secondary extruding, then bamboo pulp is filtered, it squeezes and completes to secondary filter from raw bamboo felling, total time is no more than 72h；Primary filtering squeezes
Finally the lignin of liquid, protein, amino acid and various flavones can be separated with bamboo fibre with secondary filter extruding,
(7) biological enzyme bating relieves, and softening is relieved using the prior art, can specifically refer to Chinese patent: a kind of bamboo is fine
The softening method (application number 201710936614.4, publication No. CN 107639708A) of dimension.
Lignin, amino acid, flavones, protein etc. in liquid are carried out multiple, quick separating with bamboo fibre by this technique,
Facilitate to greatest extent keep bamboo fibre integrality, it is easy to operate, low in cost, will not to environment generate pollution, meet
National green, environmental protection, low-carbon, production energy-saving theory, highly promote and apply.
Preferably, fresh bamboo wood is the fresh bamboo of activity of 3 <bamboo age≤7 and felling time no more than 48h, is grown after cutting bamboo
The bamboo section of 1-4m is spent, obtains the bamboo chip that width is not more than 40mm after fragment.
It is further preferred that classification roll in gap between milling roller at different levels it is as follows: level-one: 4-6mm, second level: 2-
4mm, three-level: 1.5-2mm, level Four: 1-1.5mm, Pyatyi: 0.5-1mm, six grades: 0-0.5mm, rolling roller diameter is 200-

It is further preferred that the grinding pressure of level-one to Pyatyi is not more than 60MPa, six grades of grinding pressure 70-160MPa.It is more
It is secondary, be gradually increased grinding pressure carry out classification roll, both can be effectively by lignin, protein, the ammonia between fiber also in liquid
Base acid and various flavones squeeze out it is most of, and will not damaged fiber, the integrality of fiber can be kept, then ensure bamboo pulp
Excellent properties.
It is further preferred that the bamboo fiber bundle that classification rolls is placed in thread rolling machine after adding water on one side when thread rolling
Heating carries out thread rolling on one side, and adding the weight percent of bamboo fiber bundle after water is 5-50%, and heating temperature is no more than 90 DEG C.Add water can
So that bamboo fiber bundle it is mutual extruding force it is soft, reduce broken, the fracture of fiber；Heating can promote in bamboo fiber bundle
Lignin, amino acid, protein and various flavones isoreactivity ingredients be quickly dissolved into water；It is of course also possible to which directly addition is hot
Water.
It is further preferred that the grinding pressure that individual fibers are born (is arranged no more than 10N under microscope when thread rolling
The fibre bundle of quantity, then presses, after fibre bundle uniformly divides column, by the pressure of application divided by fiber number it can be learnt that.),
The stroke 100-250mm of effective roller compaction process, obtains the bamboo fibre of diameter 0.03-0.1mm, length 0.5-5mm after thread rolling.
It is further preferred that amount of water is not less than twice of initial filter bamboo pulp weight when secondary filter squeezes, heating temperature is
40-90 DEG C, the mixing time of the over dry initial filter bamboo pulp of every 500Kg is not less than 1.5h.
It is further preferred that the concrete operations that biological enzyme bating relieves are as follows: bamboo pulp will be filtered again and be placed in stainless cylinder of steel and add
Heat to 60-65 DEG C, keep the temperature 1h after be cooled to 40-45 DEG C, by Endocellulase, heat-resistant alpha-amylase, beta-glucosidase,
Polygalacturonase, medium temperature amylase and liquefying amylase, which are added in stainless cylinder of steel, stirs at least 1h, the use of every kind of enzyme
The weight percent of amount and over dry bamboo pulp is respectively 0.32 ‰, 0.45 ‰, 0.35 ‰, 0.40 ‰, 0.67 ‰ and 0.56 ‰；Heating
And when heat preservation, stainless cylinder of steel is lower than 2MPa in the pressure of air-tight state and inside, and in this low pressure range, fiber hydrolization is faster.
More preferably, primary filtering, which squeezes, is first filtered using the stainless steel filter screen of 30-70 mesh, then is squeezed；Two
Secondary filtering, which squeezes, is first filtered using the stainless steel filter screen of 40-60 mesh, then carries out high-pressure extrusion, and the pressure of the high-pressure extrusion is not
Lower than 60MPa.
Highly preferred, the initial filter bamboo pulp water content that primary filtering obtains after squeezing is no more than 55%, and secondary filter squeezes
What is obtained afterwards filters bamboo pulp water content not higher than 42% again.
The present invention, by itself and bamboo fibre quick separating, has when lignin, amino acid, flavones, protein etc. are also in liquid
Help to greatest extent keep bamboo fibre integrality, it is easy to operate, low in cost, will not to environment generate pollution, meet state
Family green, environmental protection, low-carbon, production energy-saving theory, highly promote and apply.
