Problems solved by technology

Simply improving the stiffness of the finished paper will inevitably make the thickness of the finished paper too high, and the absorbency will be enhanced. The empty tube part is caused by premature wetting and collapse when the lips are in contact, which will affect the product quality.
At the same time, there are many layers of fiber stacking, and the longitudinal friction between the fibers increases. Since the empty tube part has no internal support, there is no support when it is cut on the nozzle rod machine, which increases the difficulty of cutting, and stubble appears at the end of the nozzle rod, which is serious. affect product appearance
Therefore, the hard nozzle rod forming paper is only used in countersunk rods, but it is not a product designed and developed for countersunk rods

Embodiment 1

[0029] This embodiment provides a method for producing countersunk nozzle rod forming paper, comprising the following steps:

[0030] (1) Raw material selection: use softwood pulp with fiber length ≥ 2.5mm, fiber thickness ≥ 0.14mg / m, and fiber width 28-35μm; and fiber length ≥ 0.7mm, fiber thickness ≥ 0.08mg / m, Hardwood pulp with a fiber width of 20-35 μm.

[0031] (2) The coniferous pulp and broadleaf pulp are beaten separately; among them, the coniferous pulp is beaten by three disc refiners, the first is a cutting disc refiner, which mainly cuts fibers, the second and the third are broom Disc grinding mainly plays the role of beating degree. This beating method can control the fiber length. While ensuring the beating degree of the fiber, it can control the fiber length and the brooming rate, so that the needle fiber can not be too long when the beating degree is reached, and at the same time it can be exposed. There are enough hydroxyl groups, so that the paper can ensure...

Abstract

The invention provides a production method of countersunk nozzle rod forming paper. The production method of the countersunk nozzle rod forming paper comprises the following steps: (1) pulping needle-leaf raw pulp and broad-leaf raw pulp separately, and then mixing the needle-leaf raw pulp and the broad-leaf raw pulp according to the mass ratio of (1-1.5): 1, and then adding a ground calcium carbonate solution in the mixture to obtain mixed slurry; (2) diluting the mixed slurry until the mass concentration reaches 2.5-3.5%, then adding a polyoxyethylene solution and a cationic starch solutionin the mixed slurry, further diluting the mixed slurry until the mass concentration reaches 1.5-2.5%, treating the mixed slurry through a net, and adding an alkyl ketene dimer solution; (3) dehydrating and forming the slurry treated by the net through a squeezing portion to obtain a wet paper sheet with the water content of 45-65%; and (4) carrying out pre-drying treatment on the wet paper sheet to obtain a semi-dry paper sheet, dipping the semi-dry paper sheet with a mixed solution of polyamide polyurea resin, oxidized starch and polyvinyl alcohol, carrying out after-drying treatment on the paper sheet, and rolling the paper sheet to obtain the countersunk nozzle rod forming paper.

Description

technical field [0001] The invention belongs to the technical field of forming paper preparation, and in particular relates to a production method of countersink rod forming paper. Background technique [0002] Forming paper for countersunk tip rods is a kind of forming paper used to wrap cellulose acetate tow in cigarette filter rods and directly contact with cellulose acetate tow. The main difference between this product and ordinary filter rods is that this product uses In the half-tow tip rod, the so-called half-tow tip rod refers to the cigarette tobacco section coiled filter rod, the material wrapped by the forming paper includes one or more sections of acetate tow and acetate tow composite material tip rod , and a section of empty tube which is only made of forming paper. The empty tube is independently supported by the forming paper. There is no tow or tow filler in the tube. The length of the empty tube can be adjusted according to the design of the nozzle rod.
