Abstract
The invention provides a papermaking method by oxidizing banana stemfiber, comprising the following steps of: cutting banana stem into sheets, and coarsely grinding into fiber sizing agent; washing the fiber sizing agent to remove hemicellulose, lignin, pectin and the like in a washing way; extruding to be fiber sizing agent which has 50%-60% of moisture after washing; adding quick lime and sodium hypochlorite after extruding, charging CO2 gas to oxidize the fiber sizing agent, separating impurity by a centrifugal pulp screen after oxidizing, and carrying out medium-consistency grinding on the pulp to be 32-36 beating degree in the process of separating; and mixing the sizing agent as required, so that the sizing agent is applicable to the sizing agent quality requirement of various papers. According to the invention, the papermaking method which oxidizes the banana stemfiber, and is free from stewing, pollution-free to environment, low-carbon, and energy-saving is adopted, so that the banana fiber papermaking difficulty can be effectively solved, the banana stemfiber can be softened within 40min, and the integrants which can not be used for papermaking in the hemicellulose, the lignin and the banana stem can be separated; and therefore, the banana fiber paper pulp which is suitable for making the fine paper can be obtained.
Description
Technical field
The present invention relates to a kind of papermaking process that is oxidized fibers from banana stem.
Background technology
Papermaking enterprise is restricted the bottleneck of development at present, is mainly to derive from following reason.The one, resource scarcity, the developmental process of the timber of each cube needs the very long process of 10-15 year, the 2nd, too much felling timber is for papermaking, be unfavorable for water and soil conservation, the Nature such as mud-rock flow, sandstorm disaster is of common occurrence, causes water and soil conservation imbalance to have close relationship with too much the cutting down forest of people.
Tradition paper technology uses highly basic strong acid boiling method more, produces " three wastes " and discharges unavoidable contaminated environment, has caused the attention of government and relevant department, so the row that the incomplete papermaking enterprise of environmental protection is just being shut down, stop, merge and change.But due to social progress, human civilization life all be unable to do without paper, the disparities between supply and demand of paper products are outstanding, although government department carries out the various measures such as paperless office energetically, reduce the consumption of paper product as far as possible, but always can not accomplish with no paper life, so just there are greatly different disparities between supply and demand in paper products, demand constantly increases on one side, just closing on one side, stop, and, turn, so market has openings constantly increases, bring many inconvenience to people's life, in order to alleviate these contradiction, the task of top priority is to find the ramp of a kind of energy, in process, can avoid the new alternative papermaking raw material of contaminated environment.
Five provinces and regions, China southeast are as Guangdong, Guangxi, Hainan, Fujian, 1,000 ten thousand mu more than of the provinces and regions banana planting areas such as Yunnan, because banana fruit is 8 months and a lifelong harvest growth period, so fruit tree must be cut down after receiving every year fruit, therefore annual list just has several 4,000 ten thousand tons more than with regard to banana stalk, and every 10 tons of banana stalks just can substitute the timber of one cube, and only banana stalk is with regard to the papermaking log of alternative 4,000,000 cubic meters.
Fibers from banana stem content is not less than 10%, and molecular structure and other fibre structure not something in common are: its fiber is more crisp, and after drying, slightly folding is disconnected, is difficult to achieve the goal with traditional papermaking process.
Summary of the invention
For solving an above-mentioned difficult problem, the object of this invention is to provide a kind of papermaking process that is oxidized fibers from banana stem, the present invention taking banana stalk as raw material, under normal temperature oxidation processes carry out papermaking, can make banana fiber reach softening in 40 minutes, and the part that is not useable for papermaking in hemicellulose, lignin and banana stalk is separated, obtain meeting the banana fiber paper pulp of fine paper of manufacturing paper with pulp.Technique of the present invention simply, easily grasp, less investment instant effect, has the market competitiveness, is conducive to alleviate the disparities between supply and demand of paper products.
The present invention is achieved through the following technical solutions:
A papermaking process that is oxidized fibers from banana stem, step is as follows:
(1) raw-material processing: the banana stalk of receiving after fruit is cut into sheet, adopts conventional kibbling mill that sheet banana stalk is roughly ground into fibre stuff;
(2) washing: after the fibre stuff that previous step is obtained is delivered to continuous hydraulic pulper and cleans, the vibrating screen that to flow into aperture be 6mm washs, by washing by eccysis such as hemicellulose, lignin and pectin;
(3) extruding: the fibre stuff that is squeezed to moisture content 50-60% after washing with extruder;
(4) oxidation: the fibre stuff after extruding packs in container, add the quick lime CaO of pH value 7-8 by 10% of banana stalk quality, stir 20-30 minute, in stirring, adding inchmeal content by the 5-7% of previous step gained moisture content 50-60% fibre stuff quality is 85% clorox, stop stirring and after standing 10-15 minute, passing into CO from the bottom of container at normal temperatures
2gas is oxidized fibre stuff, venting pressure 0.3-0.35 kilogram, and the time is 6-8 minute; Be oxidized after 40-45 minute with centrifugal sereen the impurity such as thick slag, dust and cane marrow that is not suitable with copy paper is separated, then carry out middle concentrated jordaning to 32-36 beating degree; Size mixing as requested, make the manufacture paper with pulp slurry matter requirement of various paper products of its adaptation.
The present invention adopt oxidation fibers from banana stem, non-evaporating boil and normal temperature under free of contamination environment, low-carbon (LC), energy-conservation papermaking process, efficiently solve a difficult problem for banana fiber papermaking, can make fibers from banana stem reach softening in 40 minutes, and the content that is not useable for papermaking in hemicellulose, lignin and banana stalk is separated, obtain meeting the banana fiber paper pulp of fine paper of manufacturing paper with pulp.
Use oxidation fibers from banana stem method provided by the invention, banana fiber fine fibre in processing procedure runs off seldom, yield is high,, the technique slurry yield of the inventor's Chinese patent CN200910114078.5 improves 20%, accomplish to make the best use of everything, fiber quality is good, is a kind of papermaking process of more environmental protection.Because of technique, advanced person is scientific and reasonable, outer row's waste water is not because containing harmful chemical addition agent, outside workshop in row's wastewater treatment process with after polyaluminium sulfate settling suspension thing again with flocculant the waste water flocculating of discharging, after flocculation, fall to slurry stock pump under pond and be extracted into after filtering on 60 object slanted screens and use as fuel by press filtration again.
