Abstract
The present invention relates to a production technique for manufacturing greaseproof paper by using salt field cladophora, which belongs to the production technique of greaseproof paper. The present invention is characterized by salt field cladophora raw material collecting, raw material wash, degumming, filter pressing, deproteinization, filter pressing, bleaching, pulping and papermaking. The present invention has the advantages of simple manufacturing technique, low cost, easy waste water treatment and high economic benefit, and produced greaseproof paper does not contain any additive. The salt field cladophora raw material used in the present invention is harmful algae in solarization salt fields and has the disadvantages of high growth rate, common coverage of a wide range of water surface, serious influence on salt field output rate and water passage blockage, and the decomposition of a large amount of salt field cladophora raw material commonly cause the eutrophication of water quality; the present invention changes the salt field cladophora raw material from bane into boon.
Description
The present invention relates to a kind of production technology of greaseproof paper, particularly a kind of production technology of making greaseproof paper with the bristle algae.
At present, domestic paper-making industry all adopt traditional raw material as: timber or grass fiber carry out papermaking as raw material, because traditional raw material contains a large amount of lignin, need be with a large amount of chemicalss during papermaking, removed this papermaking process expense cost height, and serious environment pollution through digesting technoloy; Also need in paper product, to add additives such as soap, alum, cationic retention aid agent and papermaking chemical product, paper technology complexity when making greaseproof paper.
The objective of the invention is to provide the production technology of the making greaseproof paper by using salt-field cladophora that a kind of technology is simple, cost is low, free from environmental pollution.
The object of the present invention is achieved like this: collect salt pan bristle algae raw material-→ raw material cleans-→ come unstuck-→ press filtration-→ deproteinization-→ press filtration-→ bleaching-→ making beating-→ copy paper.
In the such scheme, adopting salt pan bristle algae is that raw material carries out papermaking, has avoided handling in traditional paper technology the process of lignin, so avoided the severe contamination to environment; Because salt pan bristle algae raw material is the Exposure to Sunlight salt Tanaka fast green alga that grows, thus raw material get easily, cost is low; Because the paper that has adopted such scheme to produce is greaseproof paper, need not add additive in paper-making process, technology is simple, has reached purpose of the present invention.The salt pan bristle algae raw material that uses among the present invention is Exposure to Sunlight salt Tanaka's a harmful algae, and this fast regular meeting of algal grown speed covers large stretch of water surface; have a strong impact on the productive rate of sea salt; block water channel, regular meeting causes the water quality eutrophication when rotting in a large number, and the present invention turns bane into boon it.This invention manufacturing technique is simple, cost is low, wastewater treatment is easy, and the greaseproof paper of producing does not contain any additives, the economic benefit height.
The present invention is described in detail below in conjunction with embodiment.
Embodiment 1: collect the bristle algae from salt Tanaka, be placed under the daylight and tan by the sun; Drying is pulled the segment that algal filament rolls into the 1-2 centimeter length out after the silt foreign material are removed in cleaning, makes fine fodder; Fine fodder is soaked with the 1%-2% hydrochloric acid solution, take out after 10-12 hour in insulation under the 50-60 ℃ of condition and squeeze out acidic extraction liquid and algae-residue; Algae-residue is immersed among the dilute alkaline soln of 0.5%-2%, insulation is 8-6 hour under 50 ℃ of-60 ℃ of conditions, stirs for several times therebetween, squeezes out green juice; Clean algae-residue with clear water, get the light green algae-residue after squeezing the water out, for making beating usefulness, dark excessively as the algae-residue green, available sig water repeats above-mentioned processing procedure; Making beating then; Copy paper, this making beating; Machine hand's skill and traditional handicraft are omited together.The paper that this technology is made is green greaseproof paper.
Embodiment 2: the algae-residue of green is bleached with hydrogen peroxide or chlorine or bleaching powder; Or algae-residue placed under the daylight tan by the sun, algae-residue is bleached naturally, soak essence with 1%-2% hydrogen peroxide bleaching liquid then and float, promptly get white algae-residue, other technology is same with embodiment 1, summary.The paper that this technology is made is the greaseproof paper of white.
Claims (2)
1, a kind of production technology of making greaseproof paper by using salt-field cladophora is characterized in that: collect salt pan bristle algae raw material, and------coming unstuck,------------paper is copied in bleaching---making beating---to deproteinization in press filtration in press filtration in the raw material cleaning;
Described raw material is the bristle algae that is grown in salt Tanaka; Describedly come unstuck, press filtration is that fine fodder is soaked with the 1%-2% hydrochloric acid solution, take out after 10-12 hour in insulation under 50 ℃ of-60 ℃ of conditions and squeeze out acidic extraction liquid and algae-residue; Described deproteinization, press filtration are that algae-residue is immersed among the dilute alkaline soln of 0.5%-2%, and insulation is 8-6 hour under 50 ℃ of-60 ℃ of conditions, stirs for several times therebetween, squeezes out green juice; Clean algae-residue with clear water, get the light green algae-residue after squeezing the water out, for making beating usefulness, dark excessively as the algae-residue green, available sig water repeats above-mentioned processing procedure; Described bleaching is that the algae-residue of green is bleached with hydrogen peroxide or chlorine or bleaching powder; Or algae-residue placed under the daylight tan by the sun, algae-residue is bleached naturally, soak essence with 1%-2% hydrogen peroxide bleaching liquid then and float, promptly get white algae-residue.
2, the production technology of making greaseproof paper by using salt-field cladophora according to claim 1 is characterized in that: it is to collect the bristle algae from salt Tanaka that described raw material cleans, and is placed under the daylight and tans by the sun, dry after clean, remove the silt foreign material, pull the segment that algal filament rolls into the 1-2 centimeter length out, make fine fodder.
