Embodiment 1

[0017] The present invention is made by following raw material:

[0018] Water hyacinth 60%, calcium hydroxide 10%, talcum powder 25%, kaolin 4%, titanium dioxide 1%

[0019] The above-mentioned raw materials are added and polished into fiber pulp according to the process procedure.

[0020] Production Process:

[0021] Take an appropriate amount of water hyacinth, add a certain amount of water, add calcium hydroxide, and grind it into a slurry→cooking→screening→purify, add talcum powder and kaolin, mix and grind→add titanium dioxide for bleaching→mechanical pulping, such as adding 0.002% royal blue, fiber pulp The effect is better.

Embodiment 2

[0023] The present invention is made by following raw material:

[0024] Water hyacinth 65%, calcium hydroxide 9%, talcum powder 22%, kaolin 3%, titanium dioxide 1%

[0025] The above-mentioned raw materials are added and polished into fiber pulp according to the process procedure.

[0026] All the other features are the same as in Embodiment 1.

Embodiment 3

[0028] The present invention is made by following raw material:

[0029] Water hyacinth 70%, calcium hydroxide 6.5%, talcum powder 20%, kaolin 3%, titanium dioxide 0.5%

[0030] The above-mentioned raw materials are added and polished into fiber pulp according to the process procedure.

[0031] All the other features are the same as in Embodiment 1.

Abstract

A water hyacinth fiber pulp used as fibrous raw material for paper making is provided, which is made from fibers of water hyacinth plant of the Pontederiaceae family by paper pulp process technique. The water hyacinth fiber pulp is characterized in that the fiber pulp contains water hyacinth fibers, calcium hydroxide, talc powder, kaolin and titanium dioxide. The water hyacinth contains high-quality fibers and the fiber pulp processed from water hyacinth is used as chemical raw material for paper making and cellulose production. The invention utilizes water hyacinth fibers as raw material, which is improvement of the prior art, and helps to protect environment and restore ecological balance and simultaneously solves the problem that the water hyacinth enrichment causes the blockage of water transport, resulting in the hazard to global traffic. The invention changes waste water hyacinth to a new resource for human beings. The invention has significant social value as well as economic value.

Description

technical field [0001] The invention relates to a water hyacinth fiber pulp used for papermaking and the like. Background technique [0002] The pulp fiber raw materials currently used in the paper industry mainly include the following categories: [0003] 1. Wood fiber raw materials, such as spruce, fir, deciduous fir, hemlock, masson pine, needle pine, poplar, birch, beech, maple, etc. Wood fiber is a high-quality papermaking material with a wide range of uses. Hard, high production and processing costs, and most of the pulp depends on imports. [0004] 2. Grass fiber raw materials, such as rice straw, wheat straw, reed, bagasse, sorghum stalk, cotton stalk, hemp stalk, etc., have thicker fibers and are mostly used for processing low-grade paper. [0005] 3. Bamboo fiber raw materials, such as Yuan bamboo, Ci bamboo, white bamboo, Nan bamboo, etc. Its fibers are thick and long, and they are mostly used as raw materials for traditional craft paper and wrapping paper.
