Description
Technical field
The present invention relates to pulp technology for making paper more particularly to a kind of paper, preparation method and dresses for adding tabacco straw
It sets.
Background technique
China is the big country of tobacco leaf planting and tobacco leaf production at present, but the utilization ways of non-tobacco leaf resource at this stage are few,
Also the condition for not yet forming industrialization, causes the waste of vast resources.But there is 150~1,600,000 tons of tabacco straw without out every year
Road.Tabacco straw is rich in having lignin, cellulose and nicotine, and tabacco straw is burnt up by tobacco grower as fuel, the burning of cigarette stalk
It is not only easy to propagate to poison, but also is easy to pollute the air of rural area and surrounding enviroment.
To make full use of tabacco straw, it is thus proposed that tabacco straw is used for papermaking or fiberboard, such as Chinese patent application
CN1059946 discloses a kind of " technology for making paper pulp with pure tobacco stalk by imine method ", using full cigarette stalk as papermaking body material papermaking,
Taking full advantage of tabacco straw, preparation process includes procedure for preparation, cooking process, defibrination process, washing process, pulping process,
But since paper technology usually requires to carry out slurrying, the paper maker of paper making raw material based on tabacco straw to body material timber
Skill needs to carry out pulping by cooking to tabacco straw, not only needs a large amount of chemicals to the boiling of tabacco straw, can also generate a large amount of
Waste water causes environmental pollution, if the disclosure patent carries out boiling to tabacco straw with using neutral imines method, can generate big quantization
Learn waste water, welding.In addition, the full cigarette stalk paper of raw material and the raw material based on common wood pulp based on tabacco straw
Paper compare, paper strength can be remarkably decreased, and influence paper service performance.
Summary of the invention
The object of the present invention is to provide a kind of paper, preparation method and devices for adding tabacco straw, in paper making pulp
Add appropriate amount tabacco straw powder, can keep paper strength variation less in the case where significantly improve Paper bulk and

Measurement result such as the following table 1, the paper of addition tabacco straw of the invention, cigarette it can be seen from following test result
When the additive amount of careless stalk powder is 0.01-30%, the strength character of paper influences less, and Paper bulk has and significantly mentions
It is high.Comprehensively consider paper strength performance and Paper bulk, the additive amount of the choosing of tabacco straw powder is 1%-7% in paper.
The performance test results of the paper of the different tabacco straw powder additive amounts of table 1
The further paper to the tabacco straw powder additive amount range for having both good strength character and Paper bulk
Ingredient analyzed, wood pulp price is based on 4000 yuan/ton, and tobacco rod price is based on 500 yuan/ton.
Result such as the following table 2 is analyzed, adds tabacco straw and addition wood pulp in paper it can be seen from following test result
On the basis of obtained Paper bulk and paper strength index value is comparable, the average cost value for adding wood pulp is 4000 yuan, is added
The value at cost for adding tabacco straw is 3860.Realize that tabacco straw fiber natural resources fully and rationally uses, investment is small, at low cost,
Comprehensively consider paper strength performance, Paper bulk and production cost, the more preferred addition of tabacco straw powder in paper
Amount is 5%.
The performance test of the paper of the different tabacco straw powder additive amounts of table 2, cost calculation result
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
