Problems solved by technology

[0003] Although there are many methods and reports on the recycling of tea dregs, the stock of tea dregs is still very large. It is still of great economic importance to study new methods of recycling tea dregs to alleviate the environmental cleaning pressure brought about by tea dregs. Value and significant environmental significance

Embodiment 1

[0036] In this example, a paper machine is used to prepare tea paper for writing. The specific method is as follows:

[0037] 1) Dry the recovered tea dregs, then grind and smash, and sieve to obtain 60-80 mesh tea dregs powder;

[0038] 2) Mix 20kg of tea dregs powder with 50kg of wood pulp raw materials and 30kg of Asparagus grass material to make paper pulp;

[0039] 3) Feed the pulp of step 2) into the paper machine and prepare it to have a weight of 40-200g / m 2 Commodity paper.

[0040] The paper machine used in this example is a 1575 paper machine, which has been reformed after years of exploration. The principle is different from other ordinary paper machines. The paper machine in this example is replaced with artificially woven bamboo curtains in the mesh part, which completely imitates the papermaking of handmade paper. Molding technology. In addition, after the paper is pressed, the link to the dryer section ensures that the paper will not be wrinkled or damaged. details a...

Embodiment 2

[0059] In this example, hand-made paper is used to prepare tea paper for writing. The specific method is as follows:

[0060] 1) Dry the recovered tea dregs, then grind and smash, and sieve to obtain 60-80 mesh tea dregs powder;

[0061] 2) Mix 10kg of tea dregs powder with 50kg of wood pulp raw materials and 20kg of Asparagus grass material to make paper pulp;

[0062] 3) Manually make paper from the pulp of step 2) to prepare a gram weight of 40-200g / m 2 Commodity paper.

[0063] This example is produced by a purely manual process, the paper is relatively soft and breathable, and the printing and writing effect is better. The specific process of manual papermaking is as follows:

[0064] 1) Rinse, pass the made pulp into the bleaching tank to remove impurities;

[0065] 2) Papermaking: the rinsed pulp is transported to the tank through a pipeline, and the paper is made by manual bamboo curtains using the "wave method";

[0066] 3) Squeezing, the wet paper made by manual frying is presse...

Abstract

The invention discloses a method for recycling tea leaf residues and tea paper for writing. The method for recycling tea leaf residues comprises the following steps that (1) the tea leaf residues are dried, grinded and smashed, and tea leaf residue powder of 60-80 meshes is obtained by screening the tea leaf residues; (2) by weight, 10-20 parts of tea leaf residue powder, 30-50 parts of wood pulp raw materials and 20-30 parts of Chinese alpine rush materials are mixed evenly to prepare paper pulp; and (3) the paper pulp is fed into a papermaking machine or traditional paper picking is conducted, and commercial paper with the gram weight being 40-200 g / m<2> is obtained. According to the method, the tea leaf residue powder and the wood pulp raw material are mixed to prepare the paper pulp, the commercial paper suitable for writing is produced, a new means and a solution are provided for recycling of the tea leaf residues, the environment cleanliness pressure caused by the tea leaf residues is relieved, and great economic value and great significance in environmental protection are achieved. The tea paper for writing has a faint fragrance of tea and has a good sensory effect, the tea leaf residues are applied by a large scale, the wood pulp raw materials are saved, and the papermaking cost is effectively reduced.

Description

Technical field [0001] The present application relates to the field of tea residue recycling, in particular to a method for tea residue recycling and writing tea paper obtained based on the method. Background technique [0002] Tea is our country's advantageous specialty resources. The deep processing of tea has developed rapidly, and the by-products of deep processing of tea have increased sharply, but they have not been effectively recycled, which puts a lot of pressure on the clean environment. Tea dregs are solid wastes after tea soaking and extraction, and it is also the main by-product of deep processing of tea deep processing enterprises. Although there are reports that the organic-inorganic compound fertilizer made from tea residues can significantly promote the growth of new shoots of crops and increase the yield and quality of crops; however, its economic benefits are still not satisfactory. There are also reports on the innovative model of making mosquito coils and pi...
