Plant fiber solubilizer and method for preparing plant fiber at room temperature

Abstract

The invention discloses a plant fiber relieving agent, which is prepared from, by mass percent, 35-45% of sodium carbonate, 25-35% of calcium hydroxide, 5-15% of sodium sulfate, 5-15% of hydrogen peroxide, 5-10% of saccharomycetes, 0.5-1.5% of hydrochloric acid, and 0.5-1.5% of formalin. By mixing sodium carbonate, calcium hydroxide, sodium sulfate, hydrogen peroxide, saccharomycetes, hydrochloricacid and formaldehyde at proper ratio (as described above), the plant fiber relieving agent generates neutralization, and penetrates to decompose a plant wall, soften the plant fiber and disperse other components; the plant fiber can quickly soften and relieve brooming and protect fiber and semifiber from excessive damage. Therefore, the plant fiber relieving agent can relieve plant fiber under the constant temperature, the fiber yield is naturally increased, and the produced fiber has very strong antioxidant and corrosive resistance, and can be placed without rotting for one year.

Description

technical field [0001] The invention relates to a plant fiber debonding agent and a method for preparing plant fibers at room temperature, belonging to the field of papermaking. Background technique [0002] Since Cai Lun invented the technology of extracting plant fiber to make paper in the Eastern Han Dynasty of my country, although the technology of extracting plant fiber and papermaking has made great progress in many aspects, it still has not got rid of the following shortcomings in traditional technology: [0003] One is to soak the plants with strong alkali and strong acid for a long time to soften the fibers. In order to shorten the time, the amount of acid and alkali can be increased or the temperature can be increased. In this process, harmful black liquor will inevitably be produced, causing pollution discharge; [0004] The second is that the plants soaked in strong alkali and strong acid need to extract fibers, and they must be cooked at a high temperature above...

Problems solved by technology

[0002] Since Cai Lun invented the technology of extracting plant fiber to make paper in the Eastern Han Dynasty of my country, although the technology of extracting plant fiber and papermaking has made great progress in many aspects, it still has not got rid of the following shortcomings in traditional technology:

[0003] One is to soak the plants with strong alkali and strong acid for a long time to soften the fibers. In order to shorten the time, the amount of acid and alkali can be increased or the temperature can be increased. In this process, harmful black liquor will inevitably be produced, causing pollution discharge;

[0004] The second is that the plants soaked in strong alkali and strong acid need to extract fibers, and they must be cooked at a high temperature above 200°C, which consumes coal and electricity and increases pollution;

[0005] The third is that the water consumption is large when the plants are soaked, and the amount of water used when cleaning the plant fibers after extraction is also large, resulting in excessive waste of water resources;

[0006] Fourth, the soaking and cooking process causes too much loss to plant fibers and semi-fibers, and the fiber yield is low
