Experiment group two;
weighing 50g of corn starch and 50g of cassava starch, mixing and diluting to the concentration of 33%, adding 1g of polyamine salt derivative and 18mg of α -amylase into the diluent, uniformly stirring to prepare slurry, carrying out enzymolysis on the slurry at 84 ℃ for 20 minutes to prepare enzymatic hydrolysate, rapidly heating the enzymatic hydrolysate to 135 ℃ by high-temperature high-pressure steam, carrying out enzymatic inactivation, cooling to 90 ℃ to prepare a glue solution, measuring the pH value of the glue solution, measuring the viscosity of the glue solution at 80 ℃, 70 ℃, 60 ℃ and 50 ℃, measuring the content of 325-mesh residues, and recording.
A first control group;
weighing 35g of corn starch and 65g of cassava starch, mixing and diluting until the concentration is 33%, adding α -amylase with the mass of 15mg into the diluent, uniformly stirring to prepare slurry, carrying out enzymolysis on the slurry at 84 ℃ for 20 minutes to prepare enzymatic hydrolysate, rapidly heating the enzymatic hydrolysate to 135 ℃ by high-temperature high-pressure steam, inactivating the enzyme, cooling to 90 ℃ to prepare a glue solution, measuring the pH value, measuring the viscosity at 80 ℃, 70 ℃, 60 ℃ and 50 ℃, measuring the content of 325-mesh screen residues, and recording.
A second control group;
weighing 50g of corn starch and 50g of cassava starch, mixing and diluting until the concentration is 33%, adding α -amylase with the mass of 18mg into the diluent, uniformly stirring to prepare slurry, carrying out enzymolysis on the slurry at 84 ℃ for 20 minutes to prepare enzymatic hydrolysate, rapidly heating the enzymatic hydrolysate to 135 ℃ by high-temperature high-pressure steam, inactivating the enzyme, cooling to 90 ℃ to prepare a glue solution, measuring the pH value, measuring the viscosity at 80 ℃, 70 ℃, 60 ℃ and 50 ℃, measuring the content of 325-mesh screen residues, and recording.
The recorded values of the pH values of the experimental group I, the experimental group II, the control group I and the control group II, the viscosities at 80 ℃, 70 ℃, 60 ℃ and 50 ℃ and the content of 325-mesh screen residues are prepared into a table I.
Watch 1
As can be seen from the table I, after the polyamine salt derivative with the corresponding mass is added to the experimental group I and the experimental group II, the contents of 325-mesh residues of the prepared glue solution are obviously lower than those of the control group I and the control group II without the polyamine salt derivative. The other parameters of the experimental group I and the experimental group II are basically consistent with those of the comparison group I and the comparison group II, the PH values are kept between 5.8 and 6.4, and the viscosity of the prepared glue solution is tested to know that the viscosity of the prepared glue solution is basically unchanged no matter whether the polyamine salt derivative is added or not, so that the aging characteristic of the glue solution is not influenced by the added polyamine salt derivative. FIG. 3 is a line diagram illustrating aging tests of the sizing composition prepared according to the present invention. The two broken lines superimposed on the top in FIG. 3 represent the viscosity values at 80 deg.C, 70 deg.C, 60 deg.C and 50 deg.C of the first experimental group and the first control group, and it can be seen from the graph that the viscosity values at 80 deg.C, 70 deg.C, 60 deg.C and 50 deg.C of the glue solution prepared by the first experimental group with the polyamine salt derivative added thereto and the glue solution prepared by the first control group are almost identical, which is illustrated in the following table for corn: when the cassava content is 35:65, whether polyamine salt derivatives are added or not has no influence on the aging characteristic of the glue solution. The following two tables of broken lines in FIG. 3 represent viscosity values at 80 deg.C, 70 deg.C, 60 deg.C and 50 deg.C for the second experimental group and the second control group, and it can be seen from the graphs that the viscosity values at 80 deg.C, 70 deg.C, 60 deg.C and 50 deg.C for the glue solution prepared by the second experimental group with the polyamine salt derivative added thereto and the glue solution prepared by the first control group are almost identical, which is illustrated in the following table for corn: when the cassava content is 50:50, whether polyamine salt derivatives are added or not has no influence on the aging characteristic of the glue solution.
Because polyamine salt derivatives can decompose proteins in corn starch, the use of inexpensive corn starch and polyamine salt derivatives in large quantities in the size liquor can reduce the screen residue in the size liquor and can also save costs. Please refer to table two, which is a graph of the cost per ton of paper for the sizing dope prepared in the present invention. Because the cost of the corn starch is lower than that of the cassava starch, when the ratio of the corn starch to the cassava starch is 2: 8, the price of the dry starch per ton of the glue application liquid is 2921.33 yuan, and when the ratio of the corn starch to the cassava starch is 5: 5, the price of the dry starch per ton of the glue application liquid is 2769.2 yuan, compared with the cost, 152.12 yuan is reduced, and therefore, the cost of the dry starch of the glue application liquid is saved when the using amount of the corn starch is increased. The glue solution for sizing of each ton of paper is fixed, when the cost of the dry starch of each ton of glue solution is reduced, the cost of the glue solution prepared from the dry starch of the glue solution is reduced, and finally the glue coating weight of each ton of paper per square meter is 300g, so that the glue solution for each ton of paper can be saved by 3.73 yuan, and the paper making quantity of a large-scale paper mill per year is more than one hundred thousand tons, thereby saving a large amount of cost of the glue solution and bringing greater benefits to the paper mill.
