Problems solved by technology

[0002] The medicine box is the medicine packaging box. After the medicine is taken, the medicine box will directly become waste paper, but the medicine box is different from ordinary waste paper. To protect the waste paper, it also increases the difficulty of the treatment of the waste paper of the medicine box. The existing waste paper deinking method is to beat the waste paper first, and then perform the deinking treatment, so that it is difficult to separate the crushed film from the pulp. , which reduces the deinking efficiency and increases the deinking cost of waste paper

Embodiment 1

[0017] A method for deinking the waste paper of a veterinary drug box, comprising the following steps:

[0018] (1) Freezing: After the medicine box is recovered, rinse the surface debris and place it in a cold storage at -32°C for 10 hours to reduce the binding ability between the coating and the medicine box, and obtain a frozen medicine box;

[0019] (2) Hot blanching: Steam the frozen medicine box at 126°C for 20 minutes to reduce the binding ability of the film and ink to the waste paper fiber, improve the binding fastness of the ink and the composite, and remove a large amount of ink when the film is removed. Improve the whiteness and yield of pulp, take it out, and get a blanching medicine box;

[0020] (3) Soaking: Put the blanching kit in the soaking liquid, ferment and soak at 32°C for 2 days, 28kHz ultrasonic for 30 minutes, ferment with various microorganisms, reduce the binding ability of ink, film and waste paper fiber, and directly filter Remove the film, remov...

Embodiment 2

[0027] A method for deinking the waste paper of a veterinary drug box, comprising the following steps:

[0028] (1) Freezing: After the medicine box is recovered, rinse the surface debris and place it in a cold storage at -31°C for 11 hours to reduce the binding ability between the coating and the medicine box, and obtain a frozen medicine box;

[0029] (2) Hot ironing: Steam the frozen medicine box at 128°C for 24 minutes to reduce the binding ability of the film and ink to the waste paper fiber, improve the binding fastness of the ink and the composite, and remove a large amount of ink when removing the film. Improve the whiteness and yield of pulp, take it out, and get a blanching medicine box;

[0030] (3) Soaking: Put the blanching kit in the soaking liquid, ferment and soak at 33°C for 2 days, 29kHz ultrasonic for 33 minutes, ferment with various microorganisms, reduce the binding ability of ink and film and waste paper fibers, and can be directly filtered Remove the fi...

Embodiment 3

[0037] A method for deinking the waste paper of a veterinary drug box, comprising the following steps:

[0038] (1) Freezing: After the medicine box is recovered, rinse the surface debris and place it in a cold storage at -30°C for 12 hours to reduce the binding ability between the coating and the medicine box, and obtain a frozen medicine box;

[0039] (2) Hot ironing: Steam the frozen medicine box at 130°C for 25 minutes to reduce the binding ability of the film and ink to the waste paper fiber, improve the bonding fastness of the ink and the composite, and remove a large amount of ink when removing the film. Improve the whiteness and yield of pulp, take it out, and get a blanching medicine box;

[0040] (3) Soaking: Put the blanching kit in the soaking liquid, ferment and soak at 34°C for 3 days, 30kHz ultrasonic for 35 minutes, ferment with various microorganisms, reduce the binding ability of ink and film and waste paper fibers, and directly filter Remove the film, remov...

Abstract

The invention mainly relates to the technical field of printing and discloses a method for deinking veterinary medicine box waste paper. The method comprises the steps of freezing, performing hot ironing, soaking and removing sand. The method is simple, large equipment is not needed, popularization is facilitated, a membrane on the surface of the medicine box can be removed simply and integrally,the yield of paper pulp is 87.3 percent, the whiteness of the paper pulp is obviously improved, and the new method for deinking veterinary medicine box waste paper is provided; the waste paper is subjected to cleaning and impurity removal and then is frozen, the binding capacity of the membrane and the medicine box is reduced, steaming is conducted at high temperature and under high pressure, thebinding capacity of the membrane and printing ink on the waste paper fiber is reduced, and the whiteness and the yield of the paper pulp are increased; after the medicine box is subjected to hot ironing, the medicine box is placed into soaking liquid to be soaked and fermented, fermentation of various microorganism is conducted, the binding capacity of the printing ink, the membrane and the wastepaper fiber is reduced, the membrane can be directly filtered and removed, the printing ink is removed quietly, addition of a large of deinking agent and repeated floatation in the traditional methodare avoided, energy is saved, environmental friendliness is achieved, and the yield of the paper pulp is increased.
