Embodiment 1
[0026] A preparation method for colored translucent fruit bag paper, comprising the following steps:
[0027] 1) beating, get 25 parts by weight of hardwood raw materials, 35 parts by weight of softwood raw materials, 15 parts by weight of deinked pulp, and 10 parts by weight of bagasse raw materials for beating with a hydraulic disintegrator respectively to obtain slurry respectively, when beating Adjust the pH value to 5 with acetic acid, mix in 0.05 parts by weight of softening agent and 0.05 parts by weight of beating enzyme, and control the degree of beating at 70°SR; the beating enzyme is composed of the following mass fractions: 5% cellulase , 4% hemicellulase, 4% xylanase, 4% phospholipase, 0.5% Span 60, 0.02% potassium sorbate, 1% laccase, and the balance is deionized water;
[0028] The enzyme activity of the cellulase in the beating enzyme preparation is 800U / mL, the enzyme activity of hemicellulase is 300U / mL, the enzyme activity of xylanase is 200U / mL, and the enz...
Embodiment 2
[0037] A preparation method for colored translucent fruit bag paper, comprising the following steps:
[0038] 1) beating, get 28 parts by weight of hardwood raw materials, 40 parts by weight of softwood raw materials, 18 parts by weight of deinked pulp, and bagasse raw materials of 15 parts by weight for beating with a hydraulic disintegrator respectively to obtain slurry respectively, when beating Adjust the pH value to 5.5 with acetic acid, mix in 0.2 parts by weight of softening agent and 0.08 parts by weight of beating enzyme, and control the degree of beating at 75°SR; the beating enzyme is composed of the following mass fractions: 8% cellulase , 5% hemicellulase, 5% xylanase, 4.5% phospholipase, 0.8% Span 60, 0.03% potassium sorbate, 1.5% laccase, and the balance is deionized water;
[0039] The enzyme activity of the cellulase in the described beating enzyme preparation is 1200U / mL, the enzyme activity of hemicellulase is 400U / mL, the enzyme activity of xylanase is 300U...
Embodiment 3
[0047] A preparation method for colored translucent fruit bag paper, comprising the following steps:
[0048] 1) beating, get the hardwood raw material of 30 weight parts, the coniferous wood raw material of 50 weight parts, the deinked pulp of 20 weight parts, the bagasse raw material of 20 weight parts respectively hydraulic cracker beating, respectively obtain slurry, when beating Adjust the pH value to 6 with acetic acid, mix in 0.5 parts by weight of softening agent and 0.1 parts by weight of beating enzyme, and control the beating degree at 80°SR; the beating enzyme is composed of the following mass fractions: the beating enzyme is composed of the following mass fraction Composition of fractions: 10% cellulase, 6% hemicellulase, 6% xylanase, 5% phospholipase, 1% Span 60, 0.03% potassium sorbate, 2% of laccase, and the balance is deionized water;
[0049] The enzyme activity of the cellulase in the described beating enzyme preparation is 1500U / mL, the enzyme activity of ...
