Problems solved by technology

[0004] The problem of the chemical pulping method is that the alkali content in the pulping wastewater is high, the pulping wastewater and the subsequent papermaking wastewater are difficult to treat, and the pulp yield is low
The biological treatment agent used in the biopulping method is mainly some biological flora and its metabolites, which have a slight effect on the lignin in the plant raw material, and it is difficult to produce high-quality pulp

Embodiment 1

[0035] The environment-friendly pulping and papermaking modifier of the present embodiment is made by mixing the following raw materials in mass percentage: 10% potassium hydroxide, 14% sodium sulfate, 8% calcium oxide, 7% hydrogen peroxide, 1% white rot fungus, and The amount is water.

[0036] Mix potassium hydroxide, sodium sulfate, calcium oxide, hydrogen peroxide, white rot fungus and water in a mixing tank for 1 hour to obtain the modifier. It is a colorless liquid, a small part of calcium peroxide precipitates at the bottom of the modifier.

Embodiment 2

[0038] The environment-friendly pulping and papermaking modifying agent of the present embodiment is made by mixing raw materials in the following mass percentages: 5% potassium hydroxide, 7% sodium sulfate, 5% calcium oxide, 5% hydrogen peroxide, 0.5% white rot fungus, and The amount is water.

[0039] Mix potassium hydroxide, sodium sulfate, calcium oxide, hydrogen peroxide, white rot fungus and water in a mixing tank for 2 hours to obtain the modifier.

Embodiment 3

[0041] The environment-friendly pulping and papermaking modifier of the present embodiment is made by mixing the raw materials in the following mass percentages: 7% potassium hydroxide, 10% sodium sulfate, 6% calcium oxide, 6% hydrogen peroxide, 0.8% white rot fungus, and The amount is water.

[0042] Mix potassium hydroxide, sodium sulfate, calcium oxide, hydrogen peroxide, white rot fungus and water in a mixing tank for 2 hours to obtain the modifier.

Abstract

The invention belongs to the field of papermaking, and relates to an environment-friendly pulping and papermaking composition, a modifier and an environment-friendly pulping and papermaking method. The composition consists of the following raw materials in parts by weight: 5-10 parts of potassium hydroxide or sodium hydroxide, 7-14 parts of sodium sulfate, 5-8 parts of calcium oxide, 5-7 parts of hydrogen peroxide and 0.5-1 part of white rot fungi. In the composition, the potassium hydroxide and the sodium hydroxide play a role in softening and decomposing, the sodium sulfate plays a role in permeating, the calcium oxide and the hydrogen peroxide have the functions of strong oxidation, sterilization, disinfection and avoiding the blackening or decay of raw materials, and the white rot fungi can degrade lignin and improve the pulping speed. When the composition is to be used, the composition and water are mixed for use, all the raw material components are matched with one another, a good dissociation effect on plant fiber raw materials is achieved, the paper pulp yield can be increased, and the wastewater treatment difficulty can be reduced.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to an environment-friendly pulping and papermaking composition, a modifier, and an environment-friendly pulping and papermaking method. Background technique [0002] Pulp is a fibrous substance made from plant fibers through different processing methods. According to the processing method, it can be divided into mechanical pulp, chemical pulp and chemical mechanical pulp; it can also be divided into wood pulp, straw pulp, hemp pulp, reed pulp, sugarcane pulp, bamboo pulp, rag pulp, etc. according to the fiber raw materials used. According to different purity, it can be divided into refined pulp, bleached pulp, unbleached pulp, high-yield pulp, semi-chemical pulp, etc. Generally used in the manufacture of paper and cardboard. [0003] Traditional pulping refers to the production process of using chemical methods, mechanical methods or a combination of both to dissociate plant...
