Abstract
The invention discloses a high-strength kraft linerboard manufacturing method comprising steps of smashing, grading, heat-decentralized processing, pulping, forming, squeezing, drying and press-polishing. The beneficial effects are that examinational indexes such as folding and breaking resisting capacities of the high-strength kraft linerboard can be improved by 30% compared with common kraft linerboards, so demands of downstream clients to high-strength finished paper can be met.
Description
Technical field
The present invention relates to the technical field of papermaking, more particularly, to a kind of high-strength craft paper making side
Method.
Background technology
Extensively, its production technology compares craft paper range relatively with for other packing boards
Higher, mainly slurrying, paper manufacturing streams are more complicated.The quality technology of product requires also to compare
High.The closure of craft paper manufacture process grey water system and the decline of raw materials quality, for ensureing into
The intensity of paper, needs to develop the papermaking process of some raising paper strengths.
Content of the invention
It is an object of the invention to provide a kind of high-strength craft paper manufacture method, to solve paper strength
The problem declining.
The invention provides a kind of high-strength craft paper manufacture method, comprise the following steps：
1. by waste paper in pulper size degradation at a temperature of 50 ± 3 DEG C, revolve at a high speed in pulper
In the presence of the rotor turning and waterpower, final size degradation becomes the slurry of 3-5%；
2. by the centrifugal force of HC Cleaner, by weight thick to fiber and iron nail, glass dregs etc.
Impurity separates, and the heavy seeds isolated pass through the tail slurry pipe removal system of HC Cleaner,
And the good slurry pipe that the slurry purifying passes through HC Cleaner enters subsequent processing；
3. through two sections of classifying screens, slurry is sorted as short fine, middle fine and three kinds of fibre lengths of long fibre
Different slurries；
4. pass through the vacuum draw of polydisc thickener, by the slurry having sorted by 0.8-1.0%'s
Concentration is condensed into the concentration of 8-10%；
5. the slurry after concentrating is through heat dispersion machine in 100 DEG C of heating and heat dispersion machine abrasive disc
The decentralized processing in 0.2mm gap, tiny sicker in dissolving slurry, improves stock quality；
6. through the making beating of mill, fiber carries out profit and rises and wire-dividing broom purification the slurry after dissipation of heat,
Improve the bond strength of fiber in slurry.Slurry after making beating is delivered to paper machine and is carried out copy paper；
7. by the conveying of approach system, approach flow molding, and through press section press；
8. to squeezing after paper pulp through 6 groups of drying cylinders plus steam drying, film transfer applying glue, 3
The steam drying again of group drying cylinder；
9. load the line pressure of 45KN/m at 120 DEG C with twice calender by the paper pulp of re-dry
Carry out press polish process, improve into the smoothness of paper, after press polish, form high-strength craft paper.
Described press sections be twice shoe press with together with glazing press, specifically include：
1. the paper web through wet end molding enters press section；
2. pass through the squeezing paper web preliminary hydro-extraction of first boots pressure；
3. the squeezing paper web through second boots pressure is dehydrated further；
4. drying section is entered by the process paper web of the 3rd road glazing press.
Described operating procedure also includes blocking, by reel machine and rewinding machine, the high-strength cattle being formed
Paper carries out cutting volume bag.
Beneficial effects of the present invention are：The high-strength craft paper that the present invention makes is than common craft paper
Folding, the resistance to material index such as broken improve 30%, meet the needs to paper strength for the downstream client.
Specific embodiment
Below embodiments of the present invention are further described in detail：
The embodiment of the present invention additionally provides a kind of high-strength craft paper manufacture method, comprises the following steps：
1. by waste paper in hydrabrusher size degradation at a temperature of 50 ± 3 DEG C, high in pulper
In the presence of the rotor of speed rotation and waterpower, repulping of waste paper is become the slurry of 3-5%, and
Part heavy seeds and big light impurity are removed by chute and sediment well；
2. by the centrifugal force of HC Cleaner, by weight thick to fiber and iron nail, glass dregs etc.
Impurity separates, and the heavy seeds isolated pass through the tail slurry pipe removal system of HC Cleaner,
And the good slurry pipe that the slurry purifying passes through HC Cleaner enters subsequent processing；
3. through two sections of classifying screens, slurry is sorted as short fine, middle fine and three kinds of fibre lengths of long fibre
Different slurries；
4. pass through the vacuum draw of polydisc thickener, by the slurry having sorted by 0.8-1.0%'s
Concentration is condensed into the concentration of 8-10%, thus preparing for dirt count；
5. the slurry after concentrating is concentrated further through the propelling worm of heat dispersion machine, will starch
Material concentration improves to 28-30%, and the slurry after concentration heats at dissipation of heat preheating screw
To 100 DEG C with again through the decentralized processing in heat dispersion machine main frame abrasive disc 0.2mm gap, molten
Tiny sicker in solution slurry, improves stock quality.Pass through again in dissipation of heat outlet slurry
The process of dilution water, the concentration of pulp dilution to 5.5-6.5%；
6. through the making beating of mill, fiber carries out profit and rises and wire-dividing broom purification the slurry after dissipation of heat,
Improve the bond strength of fiber in slurry.Slurry after making beating is delivered to paper machine and is carried out copy paper；
7. the conveying by approach system for the slurry that slurrying comes, slurry is surfed the Net in head box outlet
Type, and through press section press；
8. to squeezing after paper pulp through 6 groups of drying cylinders plus steam drying, film transfer applying glue, 3
The steam drying again of group drying cylinder；
9. load the line of 45KN/m at 120 DEG C with twice calender by the paper pulp of re-dry
Pressure carries out press polish process, improves into the smoothness of paper, forms high-strength craft paper after press polish.
Described press sections be twice shoe press with together with glazing press, specifically include：
1. the paper web through wet end molding enters press section；
2. pass through the squeezing paper web preliminary hydro-extraction of first boots pressure；
3. the squeezing paper web through second boots pressure is dehydrated further；
