Abstract
The invention provides a sea buckthorn pulping method which adopts mechanical pulping technique; with the method, raw material has wide sources, and a mechanical environment-friendly pulping mode without adding alkali and other chemical substances is adopted; the pulp yield rate reaches 76.5 to 82.5 percent and no pollution produces in the production process.
Description
Technical field
The present invention relates to a kind of pulping process of paper industry, specifically, relate to a kind of sea-buckthorn pulping process and sea-buckthorn thereof slurry.
Background technology
Corrugated paper and combination board be a kind of in light weight, materials are few, cost is low, intensity is high, shock-absorbing capacity is good, sound-absorption and heat-insulation, the green material being convenient to recycle.In recent years, because packaging industry is advocated " mould with paper generation, with paper for wood " energetically, this green material is as a kind of novel environmentally friendly packing material, the application of packaging field just progressively to pay attention to and greatly develop.This will facilitate packaging material to lightizationer development, to reduce the shipment cost.The timber waste of wooden block dish packing, wooden-box package, white pollutions such as plastic foamed liner packing, all there is comparatively serious environmental issue in these packaging material, and corrugated board is green paper product, are substitutes such as wooden block dish packing, wooden-box package and plastic foamed liner packing in the future.Since the nineties in last century, strict packaging waste lambda limiting process has successively been formulated in countries and regions such as the U.S., Canada, Japan and European Union, and China has also issued relevant policy and rules in recent years.Under these circumstances, paper products have obtained unprecedented development.Paper and cardboard have accounted for 40～50% of all packaging material.
Therefore, corrugated board is a kind of novel environmentally friendly packing material, has good use value, is the cardboard kind with investment value.And China's corrugated case industry just carrying out the industry adjustment, proposed the corrugated board manufactured goods from the requirement of unification to development in pluralism.Corrugated board not only is used for producing carton, also can be used for developing other products, such as diversification products such as corrugation furniture, corrugation toy, light weight building materials and products, paper pallet, corrugated boards.
But country is the constantly felling of restriction timber at present, and severe situation in short supply will appear in timber, therefore need continually develop the raw material of new production corrugated board, such as, some wide material sources, plant material or seeds that growth cycle is short.
Sea-buckthorn is the main ecology-economical seeds of loess hill semiarid region, and Chinese sea buckthorn wild planting area accumulative total reaches 2,000 ten thousand mu, accounts for 95% of world's sea-buckthorn gross area.The root of sea-buckthorn, stem, leaf, flower, really, particularly sea buckthorn fruit contains rich nutrient substances and bioactivator, has been widely used in many departments of national economy such as food, medicine, light industry, space flight, agriculture and animal husbandry fishery, foreign trade.Because sea-buckthorn adaptability is strong, cultivation management technology is easily grasped, and has become a kind of important economic plants resource of shaking off poverty and setting out on the road to prosperity in the loess plateau, middle reaches, China the Yellow River and the poor areas of the western region.Especially in recent years along with, multipurpose research and development comprehensive to sea-buckthorn utilize, demonstrated the sea-buckthorn wide development and utilization prospects.Sea buckthorn fruit or a small amount of leaf are only purchased by sea-buckthorn processing enterprise now, and a large amount of limbs is not utilized, and causes the waste of resource yet.
Nowadays, China's corrugated paper material year consumption figure is 1,500 ten thousand tons, and wherein the straw pulp consumption is only had an appointment 4,000,000 tons, only accounts for 27%, is that raw material comes slurrying if adopt sea-buckthorn, if sea-buckthorn branch slurry ratio accounts for 20%, is 3,000,000 tons.From future analysis, to the year two thousand twenty, if sea-buckthorn branch slurry can be brought up to 40～50% ratio, then annual requirement will reach 1200～1,600 ten thousand tons, and as seen its market space is huge.
Summary of the invention
The purpose of this invention is to provide a kind of sea-buckthorn pulping process, these method raw material sources are extensive, and adopt mechanical environment-friendly pulping mode, do not add chemical substances such as alkali, and slurry yield height and production process are pollution-free.
Another object of the present invention provides a kind of sea-buckthorn slurry of being made by sea-buckthorn branch or hippophae rhamnoides patch.
In order to realize the object of the invention, a kind of sea-buckthorn pulping process of the present invention comprises the steps:
1) earlier to sea-buckthorn cut into slices, removal of impurities handles;
2) carrying out itemize then handles;
3) steam in advance again and handle and divide silk to crumple into crude fibre;
4) at last crude fibre being carried out the classification defibrination handles.
Sea-buckthorn of the present invention is sea-buckthorn branch or sea-buckthorn wood chip.
Described section is: it is 15～20mm that sea-buckthorn is cut into length.
Described removal of impurities is handled and is carried out in sand removing machine.
Described itemize is treated to and adopts banding machine that sea-buckthorn is divided into slice.
Described pre-steaming is treated to: carry out 2～3 hours softening processing in the steam feeding sea-buckthorn bar with 1～2kg pressure.
The rubbing of described branch silk is carried out in thread rolling machine.
Described classification defibrination adopts three grades of defibrinations.Three grades of defibrinations carry out in the dense disassembler of height, middle-density refiner and low dense fiberizer respectively, the concentration of slurries is 35～40% in the dense disassembler of described height, concentration of slurry is 60～70% in the described middle-density refiner, and concentration of slurry is 80～90% in the described low dense fiberizer.
Can screen behind three grades of defibrinations and enter in the reserve pit standbyly, the slurries that filter out also can enter and carry out defibrination in middle-density refiner, the low dense fiberizer and handle, to improve slurry yield.
Pulping process of the present invention adopts pure mechanical means that the sea-buckthorn branch is put into slicer, cut into slices (bar), by machineries such as banding machine, thread rolling machine, high dense disassembler to the material conquassation, rub and tear, brooming, form fiber, decompose branch fiber process and do not add any chemical addition agent, belong to environment friendly pulping process.
By the sea-buckthorn slurry that machinery pulping of the present invention obtains, slurries yield height, slurry yield is 76.5～82.5% behind pulp washing.These slurries can be used for copying joins corrugated paper and other paper kind.
Slurry can be joined 50～30% secondary stocks (OCC) at corrugation paper machine making fluting medium with 50～70% sea-buckthorn branch pulping after handling.Through chemical examination, its performance is better than the fluting medium that the straw cleaning pulping is manufactured paper with pulp many-sided.The fluting medium of making by sea-buckthorn, tightness 0.35～0.45g/cm after testing
3, breaking length 3.5～4.5km, ring crush index 10～12N.m/g.(the index tightness 0.4g/cm of high-strength B level paper
3, breaking length 4km, ring crush index 6～7N.m/g)
