Problems solved by technology

However, the chemical pulp fibers in old newspapers have been bonded during the paper-making process, the fiber itself has a dense structure, the cavity is reduced a lot, the surface is difficult to hydrate, the fiber becomes "stiff", the viscosity decreases, and the paper strength decreases.
Recycling of wrapping paper requires higher requirements, improper handling may even cause certain harm to human health, and there are few reports on recycling of wrapping paper in existing technologies

Embodiment 1

[0033] A processing method for enhanced reuse of waste wrapping paper, comprising the following steps:

[0034] (1) Crushing treatment:

[0035] Put the bactericide and waste packaging paper into the cryogenic pulverizer according to the volume-to-weight ratio of 1mL:23g, and take out the waste paper powder after pulverization for 30 minutes;

[0036] (2) Deinking treatment:

[0037] Put the waste paper powder and deinking agent obtained in step (1) into the purification tank according to the weight volume ratio of 1g:2mL and then stir them. When stirring and deinking, use microwave heating to keep the temperature in the purification tank at 50°C, and then stir After 1h, filter waste paper raw materials;

[0038] (3) Weighing of raw materials:

[0039] Weigh the following raw materials according to the corresponding parts by weight: 60 parts of waste paper raw materials obtained in step (2), 23 parts of biomass fiber, 24 parts of composite filler, 4 parts of starch, 3 parts...

Embodiment 2

[0058] A processing method for enhanced reuse of waste wrapping paper, comprising the following steps:

[0059] (1) Crushing treatment:

Description

technical field [0001] The invention belongs to the technical field of waste paper recovery and reuse, and in particular relates to a processing method for enhanced reuse of waste packaging paper. Background technique [0002] The cost of waste paper recycling The most attractive thing about waste paper recycling has always been its low cost. However, it is impossible for waste paper to be recycled indefinitely, and the limit depends on the deterioration speed and degree of fiber quality. In the processing of old newspaper pulp, the high-yield mechanical wood pulp contained in it, including chemical thermomechanical pulp and pressure groundwood pulp, retains high lignin and stiff fibers. After mechanical disintegration, the fibers become more soft and microfibrillated, which is beneficial to the bonding of the fiber structure, and can produce tighter and smoother newsprint. However, the chemical pulp fibers in old newspapers have been bonded during the paper-making process...
