Embodiment 1

[0032] A processing method for mulberry paper, comprising the following steps:

[0033] S1. Washing, wringing and sorting the boiled and bleached mulberry skin to obtain dried mulberry skin pulp;

[0034] S2. Mix the dried mulberry pulp, warm water at 60°C, and a surfactant, beat the pulp, let it stand, and wash it with clean water to obtain the raw material slurry;

[0035] S3, adding the raw material slurry to the papermaking tank filled with water after naturally controlling the water, adding the dispersant solution and stirring evenly to obtain the papermaking slurry;

[0036] S4. Manually papermaking the papermaking slurry to obtain wet paper; wherein, the papermaking includes three times of papermaking, and the papermaking slurry is picked up in the first pass and directly poured off; the second pass of papermaking will After the paper slurry is picked up, it is shaken back and forth 25 times, and in the third papermaking process, the papermaking slurry is picked up and...

Embodiment 2

[0039] A processing method for mulberry paper, comprising the following steps:

[0040] S1. Washing, wringing and sorting the boiled and bleached mulberry skin to obtain dried mulberry skin pulp;

[0041] S2. After mixing the dry pulp of mulberry skin, warm water at 65°C and surfactant, beating continuously for 50 minutes, standing for 20 minutes, and washing with water for 40 minutes, the raw material slurry is obtained; wherein, during the beating process, the beating equipment rotates at a speed of 80r / min, in the cleaning process, the rotating speed of equipment is 110r / min; The weight of described tensio-active agent is 15wt% of the dry pulp weight of mulberry skin, and the warm water of 65 ℃ of every cubic meter is mixed with 20kg dry pulp of mulberry skin;

[0042] S3. Add the raw material slurry to the papermaking tank equipped with water after naturally controlling the water, add the dispersant solution and stir evenly to obtain the papermaking slurry; wherein, the co...

Embodiment 3

[0046] A processing method for mulberry paper, comprising the following steps:

[0047] S1. Washing, wringing and sorting the boiled and bleached mulberry skin to obtain dried mulberry skin; wherein, the cleaning is carried out in a pool, the size of the pool used is 120cm×80cm×70cm, the inner and outer surfaces of the pool are tiled, and the bottom is provided with wood Lay a gauze net on the wooden grid, and when the water is released after cleaning, the mulberry skin fiber is blocked on the gauze net; a pool of water washes 25kg of the mulberry skin;

[0048] S2. After mixing the dried mulberry pulp, warm water at 62°C and a surfactant, it was continuously beaten for 50 minutes, left to stand for 45 minutes, and washed with clear water for 80 minutes to obtain the raw material slurry; wherein, during the beating process, the beating equipment had a rotating speed of 90r / min, in the cleaning process, the rotating speed of equipment is 100r / min; The weight of described tensio...

Abstract

The invention discloses a processing method of broussonetia papyrifera bark paper. The processing method comprises the following steps: washing, wringing and picking steamed and bleached broussonetiapapyrifera bark to obtain broussonetia papyrifera bark dry pulp; mixing the broussonetia papyrifera bark dry pulp, warm water of 60-65 DEG C and a surfactant, conducting pulping, conducting standing,and conducting cleaning with clear water to obtain raw material pulp; naturally draining water in the raw material pulp, adding the raw material pulp into a papermaking tank filled with water, addinga dispersing agent solution, and conducting uniform stirring to obtain papermaking pulp; carrying out manual papermaking on the papermaking slurry to obtain wet paper, wherein the papermaking comprises three times of papermaking, the first time of papermaking comprises the steps of directly conducting spilling after papermaking, the second time of papermaking comprises the steps of conducting shaking front and back for 25-30 times after papermaking, and the third time of papermaking comprises the steps of conducting shaking front and back for 20-25 times, conducting shaking left and right for15-20 times, then conducting shaking front and back for 15-20 times after papermaking, and splitting out remaining papermaking pulp; and neatly loading obtained wet paper into a paper pressing machinefor paper pressing, and conducting drying to obtain the broussonetia papyrifera bark paper.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a mulberry skin paper and a processing method thereof. Background technique [0002] Mu tree bast fiber is much thinner than hemp, and has high strength and good toughness. As a special long fiber raw material in my country, it is mainly used to produce various high-grade special papers. With the development of the times, mulberry trees are gradually and widely used in the manufacture of various paper types such as newsprint, gift wrapping paper, and rice paper. Along with the continuous development of society, the requirement to paper is also more and more higher, but owing to being subjected to the restriction of various factors such as raw material, processing condition, market, existing mulberry paper is not very good for aspects such as painting and calligraphy. Contents of the invention [0003] Based on the technical problems existing in the background technology, t...
