Embodiment 1

[0018] A method for preparing fruit growth bagging paper from tobacco stalks, comprising the following steps:

[0019] (1) Soaking tobacco stalks: put the chopped tobacco stalks into 20-25mm long specifications into the cooking boiler, soak them in 95°C hot water for 1.5 hours, filter out the soaking liquid, and use the soaked tobacco stalks as raw materials for pulping ; The weight of the hot water is 5 times of the dry weight of the tobacco stalk. The filtered soaking liquid is concentrated into a liquid with a solute mass fraction of 50% for later use.

[0020] (2) Making tobacco stalk pulp: use a high-consistency refiner to refine the soaked tobacco stalks, the refining concentration is 10%, and the degree of grinding of the pulp is 25°SR, that is, the tobacco stalk pulp is obtained. And inject the tobacco stalk pulp into the pulp pool after knocking;

[0021] (3) Mixing pulp: Take the tobacco stalk pulp in the pulp tank after beating and the charcoal powder soaked in th...

Embodiment 2

[0029] A method for preparing fruit growth bagging paper from tobacco stalks, comprising the following steps:

[0030] (1) Soaking tobacco stalks: Put the chopped tobacco stalks into 20-25mm long specifications into the cooking boiler, soak them in 90-degree hot water for 2 hours, filter out the soaking liquid, and use the soaked tobacco stalks as raw materials for pulping ; The weight of the hot water is 7 times the weight of the dry matter of the tobacco stalk. The filtered soaking liquid is concentrated into a liquid with a solute mass fraction of 48% for later use.

[0031] (2) Tobacco stalk pulp production: The soaked tobacco stalks were refined using a high-consistency refiner with a refining concentration of 8%, and the degree of knocking of the ground pulp was 30°SR, to obtain tobacco stalk pulp.

[0032] (3) Mixing pulp: Take the tobacco stalk pulp in the pulp tank after beating and the charcoal powder soaked in the tobacco stalk soaking liquid, mix it in the same pu...

Embodiment 3

[0040] A method for preparing fruit growth bagging paper from tobacco stalks, comprising the following steps:

[0041] (1) Soaking tobacco stalks: Put the chopped tobacco stalks into 20-25mm long specifications into the cooking boiler, soak them in hot water at 98 degrees for 1.8 hours, filter out the soaking liquid, and use the soaked tobacco stalks as raw materials for pulping ; The weight of the hot water is 6 times the weight of the dry matter of the tobacco stalk. The filtered soaking liquid is concentrated into a liquid with a solute mass fraction of 52% for later use.

[0042] (2) Tobacco stalk pulp production: The soaked tobacco stalks were refined using a high-consistency refiner with a refining concentration of 12%, and the degree of beating of the ground pulp was 35°SR, to obtain tobacco stalk pulp.

[0043](3) Mixing pulp: Take the tobacco stalk pulp in the pulp tank after beating and the charcoal powder soaked in the tobacco stalk soaking liquid, mix it in the sa...

Abstract

The invention provides a method for preparing fruit growth bagging paper by utilizing tobacco stalk, including the following steps: (1) soaking tobacco stalk; (2) making tobacco stalk pulp; (3) mixing and pulp blending; (4) wet end moulding; (5) dehydration drying. The fruit growth bagging paper (fruit-bagged paper) prepared by the invention has the advantages of high air permeability, high dry / wet strength, good waterproof performance, good shading performance and difficult black drainage, the problem that the air permeability of the existing fruit-bagged paper is lower is solved, the paper can be widely applied to implantation cultivation of various fruit, fruit anti-pollution protection can be realized, and colour and lustre of fruit is maintained to be fresh.

Description

technical field [0001] The invention relates to a method for preparing fruit growth bagging paper by using tobacco stalks. Background technique [0002] With the improvement of people's living standards, while the demand for fruits continues to increase, higher requirements are also put forward for their quality. In recent years, with the promotion of fruit bagging technology, my country's demand for fruit growth bagging paper (ie fruit bag paper) is increasing. The annual need for fruit bag paper is as high as 100 billion, and 500,000 tons of pulp is needed. But at present, the air permeability of fruit bag paper is generally low or even too low. Contents of the invention [0003] The object of the present invention is to provide a method for preparing fruit growth bagging paper by using tobacco stalks. The fruit growth bagging paper (fruit growth bag paper) prepared by it has high air permeability, high dry / wet strength, good water resistance, light-shielding The advan...
