Influence Of Modified Corn Stalk Cells And Chemical Composition On The Enhancement Of Paper Products

This paper first have Specific analysis on the components of corn stalk rang, theprincipal components and Content are: the benzene and alcohol extractive content is13.52%,1%NaOH extractive content is52.91%, Klason lignin content is10.74%, the total ligninContent is13.64%, holocellulose content is57.95%, pentosan content is23.99%, pectincontent is1.35%. compared with wood, corn stalks Rang has low fiber content, short fiberlength, high level of hybrid cells, isn’t suitable for directly appling to the pulp and papermaking, but by composition analysising, the content of Hemicellulose and otherPolymerization sugar are relatively high.so corn stalk Rang is modified as paper reinforcer.Hemicellulose of corn stalk rang is isolated and purified, the optimal conditions is:liquidratio1:30,pH=7, filtrate and ethanol volume ratio of1:1, concentration of KOH6%,treatment temperature is80℃, treatment time is12h. Under the optimal position, the yieldof hemicellulose is24.38%, pentosan yield is48.81%.Then following the material properties of corn stalks rang and modifing the corn stalkRang by organic solvent ethanol. After modifing,the average fiber length is about0.45mm.during the process of modification, the decomposition process can make the molecules breakinto pieces, and increase the liquidity and permeability, which make it more easy topenetrate into the fiber. When modified corn stalks is added in pulp,it penetrates into theinternal spaces, and removes the air. The process of the above is able to increase the contactarea between the fibers, and Indirectly enhance s the links between fiber and fiber.These modified corn stalks and waste paper pulp papermaking are put to together, whenthe paper’s physical strength achieve the best, the best corn stalks rang ratio is20%to25%.The physical strength index of the sheet increased: tensile index,77.74%; central pressureindex47.07%; tear index7.59%; burst index26.72%; folding233.33%; tightness13.33%.Finally, by mixing different proportions of the corn stalks Rang,mineral wool and Cornstalk pulp as a reinforcing agent is used in cushion packaging materials. In the experiment,when the Ratio of mineral wool and modified corn stalks Rang is5%and15%, the effect is Most obvious. After experimental analysis, mineral wool fiber can improve the staticcompression strength of the pulp molding products, at the same time saving a lot of energy.
