Problems solved by technology

Compared with other pulps for papermaking, tobacco stems have not been processed by cooking, bleaching, etc., and tobacco stems themselves contain a large amount of organic matter such as hemicellulose, sugar, pectin, etc., making it difficult to use in modern high-speed paper machines. Larger technical difficulties, such as: 1. The influence of the organic matter in the tobacco stem on the paper machine system generally makes the paper machine unable to produce normally; 2. The organic matter in the tobacco stem is added to the coated white cardboard for tobacco, and the organic volatile matter content exceeds the standard; 3. If the lignin in the tobacco stem is not removed, it will have an adverse effect on the strength of the paper

preparation example Construction

[0027] A preparation method for tobacco stem coated white cardboard, comprising the following steps:

[0028] S1. Taking tobacco stem powder with a particle size of 1-200 μm, adding water to prepare a suspension, and then performing leaching and / or pressure filtration on the suspension;

[0029] S2, taking the tobacco stem powder treated in step S1 and performing cationic starch coating treatment;

[0030] S3. After mixing the tobacco stem powder coated in the step S2 with the pulp slurry, the tobacco stem coated white cardboard is prepared through pulp distribution, water filtration, dehydration by pressing, drying, and coating.

[0031] From the above description, it can be seen that the beneficial effect of the present invention lies in that the scheme of the present invention adds recycled tobacco stem powder to the pulp slurry, which reduces the production cost, and at the same time, the coated white cardboard added with tobacco stem powder also has an anti-counterfeiting...

Embodiment 1

[0058] Embodiment 1 of the present invention is: a kind of preparation method of tobacco stem coated white cardboard, comprises the following steps:

[0059] 1), the preparation and processing of tobacco stem powder: the control of the particle size of tobacco stem powder is by grinding the tobacco stem powder to a particle size of 180-200 μm; the tobacco stem powder is pretreated to remove organic matter, and the tobacco stem powder is diluted with water to prepare 10% solution, using a plate and frame filter press to filter; the tobacco stem powder treated by the filter is then coated with cationic starch, specifically:

[0060] a. Preparation of tobacco stem powder particle size control: the dried tobacco stem raw material is pulverized and pulverized by a mill to make tobacco stem powder of 180-200 μm, wherein the dried tobacco stem raw material can be dried by hot air Drying, the moisture in the tobacco stem after drying is usually controlled to be 6-10%.

[0061] b. Tob...

Embodiment 2

[0077] Embodiment 2 of the present invention is: a preparation method of white cardboard coated with tobacco stems, which differs from Embodiment 1 of the present invention only in that the number of press filtrations is twice.

Abstract

The invention discloses tobacco-stem-coated white card paper and a preparation method and application thereof. The preparation method includes the following steps that S1, tobacco stem powder with theparticle diameter of 1 micron to 200 microns is taken, water is added, suspension liquid is prepared, and then the suspension liquid is extracted and / or subjected to filter pressing; S2, the tobaccostem powder after being treated with the step S1 is taken and subjected to cationic starch coating; S3, the tobacco stem powder after being coated in the step S2 and pulp are mixed, then pulp distribution, water filtering, squeezing, dewatering, drying and coating are carried out, and the tobacco-stem-coated white card paper is prepared. The tobacco-stem-coated white card paper prepared with the technical scheme can be used for preparation of packaging paper or packaging boxes. Compared with the prior art, the technical scheme is economical and environmentally friendly, and the prepared tobacco-stem-coated white card paper has the good performance.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to white cardboard coated with tobacco stems, a preparation method and application thereof. Background technique [0002] Tobacco stems, a by-product of tobacco manufacturing, are extremely wasteful due to their limited recycling options. However, tobacco stems belong to plant fibers. If they can be effectively used in papermaking, the waste of natural resources will be greatly reduced, and at the same time, wood pulp fibers for papermaking will be saved. Compared with other pulps for papermaking, tobacco stems have not been processed by cooking, bleaching, etc., and tobacco stems themselves contain a large amount of organic matter such as hemicellulose, sugar, pectin, etc., making it difficult to use in modern high-speed paper machines. Larger technical difficulties, such as: 1. The influence of the organic matter in the tobacco stem on the paper machine system generally makes...
