Problems solved by technology

[0002] The traditional papermaking process for two thousand years has mostly used plant fibers such as wood, reeds, bamboo, etc. as the main raw material, consuming a large amount of high-quality wood, destroying the ecological balance and seriously polluting the environment
After searching domestic and foreign literature, no report has been found on the use of all discarded sunflower seed husks to make pulp

Embodiment 1

[0017] Example 1: Manufacturing pulp with sunflower seed hulls

[0018] Choose 1000 kilograms of sunflower seed skins to make pulp, and its technological process is as follows:

[0019] (1) Use a winnowing machine to remove weeds, sunflower leaves, dust and other sundries in the sunflower seed skins, and then spray with clean water to make the sunflower seed skins moist and soft, then use a roller roller to crush the sunflower seed skins into a thick filament;

[0020] (2) Soak the thick filamentous sunflower seed skin in the compound enzyme aqueous solution that has not passed the sunflower seed skin for 96 hours at room temperature to dissolve the crude protein, pectin, fat, etc. in the sunflower seed skin, and use the centrifuge to dry and dehydrate A hammer mill with a sieve gap of 20×3.2 mm is crushed into filaments, rinsed with 2,000 kg of clean water, passed through a 5-mesh sieve, and filtered with a filter press to obtain a coarse filter cake. The remaining filtrate ...

Embodiment 2

[0026] Embodiment 2: make writing paper with sunflower seed husk

[0027] Choose 1000 kilograms of sunflower seed skins to make writing paper, and the process is as follows:

[0028] (1) Use a winnowing machine to remove weeds, sunflower leaves, dust and other sundries in the sunflower seed skins, and then spray with clean water to make the sunflower seed skins moist and soft, then use a roller roller to crush the sunflower seed skins into a thick filament;

[0029] (2) Soak the thick filamentous sunflower seed skin with the compound enzyme aqueous solution submerged in the sunflower seed skin for 120 hours at room temperature to dissolve the crude protein, pectin, fat, etc. A hammer mill with a sieve gap of 20×3.2 mm is crushed into filaments, rinsed with 2,000 kg of clean water, passed through a 5-mesh sieve, and filtered with a filter press to obtain a coarse filter cake. The remaining filtrate is vacuum-absorbed with a filter cloth. Filtration of recycled waste for feed ...

Abstract

The present invention uses the sunflower seed peel as main raw material, and adopts the processes of enzymolysis, cooking and low-alkali making pulp to make pulp. Said invention can be implemented by adopting existent equipment and conventional process, the obtained pulp can be used for making various papers or paper products, and can be used as raw material for making viscose fibre, collodion and explosive, etc.

Description

technical field [0001] The invention relates to a method for making pulp, in particular to a method for making pulp with sunflower seed husks, which belongs to the manufacturing process of pulp for papermaking. Background technique [0002] The traditional papermaking process for two thousand years has mostly used plant fibers such as wood, reed, bamboo, etc. as the main raw material, consuming a large amount of high-quality wood, destroying the ecological balance and seriously polluting the environment. Searching domestic and international documents, there is no report on making pulp from all discarded sunflower seed husks. Contents of the invention [0003] The object of the present invention is to provide a method for producing pulp from sunflower seed hulls. [0004] The technical scheme that realizes the object of the present invention is: [0005] A method for making pulp with sunflower husks, using sunflower ...
