Description
Technical field
The present invention relates to a kind ofly for the manufacture of through upsetting pressure or the machine of the bag paper using breadth of upsetting pressure not, this machine has head box, wet end, press section, drying section and coil paper unit.
Background technology
The bag paper using also referred to as kraft sack paper, is made by paper pulp fiber, is mainly made by long fibered pulp, because it has larger intensity and larger paper porosity.By bag paper using Production Example as being used for the sack of packing cement or other powder products.Bag paper using important characteristic is to have larger intensity, larger porosity and enough rigidity when enough large stretchings.The load when the load in when transportation and sack are filled but necessary due to sack of this characteristic.This should occur as far as possible rapidly and not only require larger intensity and retractility for this reason, and requires larger porosity or gas permeability.Therefore, large quantity of air can spill from empty bag by the bag paper using when filling.Otherwise sack can break or a large amount of dust because Bas Discharged mouthful spills by filling.In addition, day by day require a side of paper web face, namely the sack outside afterwards also should more and more easily be printed, its prerequisite is higher fineness.
The known machine for the manufacture of the bag paper using has fibrous suspension is evenly distributed on head box on width, namely on the screen cloth in wet end or between screen cloth.In wet end, on forming net or the dehydration between two forming nets, form paper or breadth by suspension.When making multi-ply paper, paper machine has a plurality of with the corresponding wet end that sets head box respectively, and these head boxs form respectively as one deck of breadth separately.When form paper in wet end after, breadth is dewatered to dry weight content and reaches approximately 40% degree in having the press section of a plurality of press nip.In the situation that multi-ply paper, the paper web face that each breadth is guided from wet end up and down stackedly jointly and upsetting pressure becomes multilayer in press section.Need a plurality ofly, lower three front and back press nip in succession of situation mostly are in order to produce the enough large dewatering efficiencies that are used for larger dry weight content.Too little dry weight content can cause drying energy cost higher in drying section and have breadth running orbit (Bahnlauf) a large amount of stubs, poor after squeezing.In known machine, press section is designed to so-called breast roll press section, and wherein, two in three press nip form together by a common breast roll.Be drying section after press section, in drying section, the paper web face is guided through the cylinder of heating and therefore is dried.
On the inside or end of drying section, for the manufacture of have the upsetting pressure device in the machine of the bag paper using of upsetting pressure.Known upsetting pressure device is for example so-called little stretching property of wrinkle (Clupak) equipment.At this, the paper web face is jointly guided by drying drum or another roller with thicker elastic webbing.At least one position on the drying drum circumference, paper web face and elastic webbing are guided through by hold-down roller or clamping element and form and the gap narrower than the thickness of elastic webbing.Thus, elastic webbing and paper web face are with it along the traffic direction upsetting pressure.Covering by elastic webbing has prevented breadth fold visibly.Upsetting pressure has increased bag paper using toughness from now on.
The bag paper using of making on these known machine does not have for the enough fineness of better printability.Improve fineness by traditional calender, wherein, one or some press polish roll gaps are formed by columniform roller basically, cause breadth to be compressed to and make porosity be reduced to the degree of very low value.Therefore, put down in writing a kind of method in Germany Patent document DE102008043727A1, wherein, used boots formula calender after drying section, also referred to as wide roll gap calender.This boots formula calender comprises the press polish roll gap that is formed by heatable columniform counter roller basically and boots formula felt wrapped roll.This boots formula felt wrapped roll has the elasticity roller shell, and this roller shell is by being bearing in the pressure shoes guiding of the hydraulic compression on static fixedly york piece.Thus, produce press polish roll gap longer than traditional calender, pressure that have reduction.But still obviously the porosity than the bag paper using of making on the machine that there is no calender fully is lower for the porosity of the bag paper using of making like this.This causes, and the filling characteristic of sack is still poorer than traditional quality.Therefore, in known machine, always need to compromise between the printability of improving and good filling characteristic.
Summary of the invention
Technical problem to be solved by this invention is further to improve a kind of machine for the manufacture of the bag paper using, and this machine makes bag paper using realize the printability of improving, and can not use or the filling characteristic variation at this.Especially bag fineness of paper using breadth should be improved, and porosity can be greatly do not reduced.
This technical problem solves thus by the present invention: press section only is comprised of a unique press nip that is designed to the shoe press roll gap, and this shoe press roll gap is made of counter roller and shoe press roll.Only be guided through a unique press nip due to the paper web face, thereby its compression when dehydration is strong no longer like this in press section.Therefore, the porosity of bag paper using remains on higher level generally.For example record the porosity as Gurley value (ISO5636-5, TAPPI T460).Volume of air with 100ml in this records the pressure of presetting is pressed through the required time of paper.This value is less, and paper just has more pores and more ventilative.By pressing machine of the present invention, in made bag paper using, the Gurley value is less than 7s/100ml, especially is less than or equal to 5s/100ml or even is less than or equal to 3s/100ml.
Can reach higher dry weight content even up to 45% and larger by the organization plan as the press nip of shoe press roll gap, and not need a plurality of press nip now for this reason.Counter roller has columniform roller shell, and shoe press roll has by being bearing in the elasticity roller shell of pressure shoes guiding on static fixedly york piece, hydraulic compression.Can produce thus the press nip longer than general roll gap, this makes and improve dry weight content after press section.Another advantage that only has the press section of a unique press nip is, the paper web face needn't shift forming between a plurality of driving groups, different press nip, and also less loses ductility thus.This additionally produces positive effect to use and the filling characteristic of sack.
In addition, have the press section of a press nip only cause for the energy requirement of drive machines still less and maintenance and maintenance cost lower.
Can have calender in a kind of preferred machine, wherein, calender should only contain a unique press polish roll gap.Because paper web face moist in squeezing is compressible more than the paper web face of the drying drying section after, thus in squeezing the volume by an only roll gap acquisition and porosity than by with unique press polish roll gap of the calender of drying section adjacency in compression minimizing more.However, the fineness on surface still can be improved significantly.
In the favourable embodiment of another kind of the present invention, be designed to the dual laying felt rug of a unique press nip of shoe press roll gap.Improved on the one hand thus dewatering efficiency, and therefore improved again the dry weight content of paper web face, squeezed felt rug because water can squeeze out to enter respectively respectively by upside and downside from the paper web face.On the other hand, the expelling belt that the paper web face needn't be again adheres to the place from smooth pressure roller or smooth fluid-tight, this paper web face is pulled out, and this additionally increases its remaining ductility.Can reduce pulling force by higher dry weight content, that is, the speed difference between press section and drying section, this improves the paper web face equally along the ductility of traffic direction with transverse to the intensity of traffic direction.
Except in addition can be advantageously, the shoe press roll gap be the preferred 270mm at least of 220mm at least along the length of breadth traffic direction.In the situation that large length, the time of staying in press nip rises, and improves thus dehydration.
The boots formula calender of press polish roll gap that can also be by calender being designed to have lengthening by machine of the present invention improves, and this press polish roll gap is made of heatable felt wrapped roll and boots formula felt wrapped roll.Felt wrapped roll has columniform roller shell, and shoe press roll has the elasticity roller shell, and this elasticity roller shell is by being bearing in pressure shoes guiding on static fixedly york piece, hydraulic compression.Therefore the press polish roll gap of this lengthening causes smooth and cause still less compression better.
In a kind of favourable organization plan, heatable felt wrapped roll can be the bottom roller in calender.Thus, from wet end be out mostly a more smooth side paper web face downside with have the heatable felt wrapped roll of more suppressing light effect than boots formula felt wrapped roll and contact.
In addition, by in machine of the present invention, can have the upsetting pressure device in the inside of drying section, dry weight content be between 60% to 80% the time in this upsetting pressure device against traffic direction upsetting pressure paper web face.Thus, record the ductility that improves the paper web face of 5-15% than the fracture elongation.
In addition advantageously, setting makes forming net extend substantially transversely to the vibrating screen equipment that traffic direction moves back and forth in wet end.Thus, improve the intensity of paper web face when paper forms, this can compensate by the compression that reduces and form the more risk of small intensity in press section.
Be equipped with pulping device before paper machine in process, before fibrous suspension flows to head box by the equipment slots as intermediate storage mean, process fibrous suspension in different equipment in this pulping device.This equipment for described processing is fiberizer.In this fiberizer, fibrous suspension is guided and passes in two narrow gaps between the dish that relatively rotates with respect to each other.Dish is with the surface texture with rib or edge.The purpose of processing is for example to cut short fiber or make its external fibrillation by the shear load in the gap.By this processing to fiber, can affect targetedly the paper characteristic, intensity, ductility or the porosity of the breadth that for example forms afterwards and the dehydration characteristic when making breadth.
The improvement of paper characteristic can also be by existing high-concentration paste mill to realize in the pulping device by machine of the present invention attaching troops to a unit, and this high-concentration paste mill i.e. pulp treatment when the solid concentration in the suspension of having processed is between 25% to 40%.The intensity of the paper web face that has formed after also having improved thus.After flowing through high-concentration paste mill, when solid concentration is between 3 to 5%, material suspension being flowed to equipment slots (being supplied to machine from this equipment slots) before, can process material suspension in the low concentration fiberizer.The shortcoming that fiberizer is processed namely, also causes reduction to the porosity of the paper web face made thus, by only have a unique press nip, cause than traditional paper machine compression press section still less and avoid.
Can advantageously be furnished with the device of regulating for dilution water by at least one head box of machine of the present invention equally, for example it is known by EP1236828A1.Create these possibilities in this organization plan of head box, weight per unit area and fiber orientation is also regulated at width adjusted throughput, density of solid in sectional type ground therefore in some zones.When dilution water is regulated, the cross section of paper web face weight per unit area be adjusted so that in head box or before overweight position with in more water input corresponding zone and therefore reduce density of material in suspension in this zone.Otherwise in the position that kicks the beam.By therefore that improve, the weight per unit area paper web face cross section realizing bag more uniform porosity of paper using, intensity and ductility on the width of paper web face.
