Abstract
Description
Foreliggende oppfinnelse angår en fremgangsmåte for fremstilling av papir og mer spesielt innpakningspapir og -papp. The present invention relates to a method for the production of paper and more particularly wrapping paper and cardboard.
Råpapirmassen som i det vesentlige består av cellulosefibre omgjøres til en fortynnet vandig suspensjon som bringes til kassen på papirmaskinen der den fordeles på en filtreringsduk eller wire der papirarket tildannes. Dette ark blir så viderebehandlet og til slutt tørket. Kvaliteter og egenskaper for det oppnådde papir bestemmes spesielt av driftsbetingel-sene for papirmaskinen, råmassen, de forskjellige additiver som settes til suspensjonen før tildanning av arket og også produktene som belegges på papirarket efter wiren. The raw paper pulp, which essentially consists of cellulose fibres, is converted into a diluted aqueous suspension which is brought to the box of the paper machine where it is distributed on a filter cloth or wire where the paper sheet is formed. This sheet is then further processed and finally dried. Qualities and properties of the obtained paper are determined in particular by the operating conditions of the paper machine, the raw stock, the various additives that are added to the suspension before forming the sheet and also the products that are coated on the paper sheet after the wire.
Ifølge foreliggende oppfinnelse beskrives mer spesielt de produkter som tilsettes før tildanning av arket. According to the present invention, the products which are added before forming the sheet are described more specifically.
Hovedkvaliteten som ønskes for innpakningspapir er styrke, det kan imidlertid også være fordelaktig å gjøre papiret fuktighetsmotstandsdyktig. Cellulosefibrene stammer fra råpapirmassen, men også hyppig fra resirkulert papir eller papp, enkelte ganger blandet med råmasse. The main quality desired for wrapping paper is strength, however it can also be beneficial to make the paper moisture resistant. The cellulose fibers originate from the raw paper pulp, but also frequently from recycled paper or cardboard, sometimes mixed with the raw pulp.
GB-PS 2 015 614 beskriver en fremgangsmåte for fremstilling av innpakningspapir- og -pappmasser der kationisk stivelse og et basisk aluminiumpolyklorsulfat eller aluminiumsulfat settes til suspensjonen av fibre før kassen. Mengden kationisk stivelse overskrider ikke 0,4$ av vekten av cellulosefibrene. Det er kjent at kationisk stivelse bidrar til den mekaniske styrke av papiret og det ville være fordelaktig å kunne innføre meget mer enn 0,456 i suspensjonen, spesielt for å bibeholde stivelsen i det tildannede ark. I denne forbindelse er stivelse meget hydrofilt og hvis en mengde på 0,5$ overskrides, er det ikke lenger mulig å danne papirarket på wiren, bortsett fra ved sterkt å redusere produktiviteten til papirmaskinen. Ifølge foreliggende oppfinnelse er det funnet en ny prosess som muliggjør at mengder av stivelse på over 0,5$ benyttes i kassen i papirfremstillingsmaskinen. GB-PS 2 015 614 describes a method for the production of wrapping paper and cardboard pulps in which cationic starch and a basic aluminum polychlorosulphate or aluminum sulphate are added to the suspension of fibers before the box. The amount of cationic starch does not exceed 0.4% of the weight of the cellulose fibers. It is known that cationic starch contributes to the mechanical strength of the paper and it would be advantageous to be able to introduce much more than 0.456 into the suspension, especially to retain the starch in the formed sheet. In this regard, starch is very hydrophilic and if an amount of 0.5$ is exceeded, it is no longer possible to form the paper sheet on the wire, except by greatly reducing the productivity of the paper machine. According to the present invention, a new process has been found which makes it possible for quantities of starch in excess of 0.5$ to be used in the case of the papermaking machine.
I henhold til dette angår oppfinnelsen en fremgangsmåte for fremstilling av innpakningspapir og -papp, og den fremgangsmåte karakteriseres ved at det til cellulosefibermassen før arkdannelsen settes: a) mer enn 0,5 vekt-deler kationisk stivelse pr. 100 deler cellulosefibre, og b) mindre enn 1 vekt-deler aluminiumpolyklorid, angitt som According to this, the invention relates to a method for producing wrapping paper and cardboard, and that method is characterized by adding to the cellulose fiber mass before sheet formation: a) more than 0.5 parts by weight of cationic starch per 100 parts of cellulose fibers, and b) less than 1 part by weight of aluminum polychloride, indicated as
AI2O3, pr. 100 vekt-deler cellulosefibre og, eventuelt, AI2O3, per 100 parts by weight cellulose fibers and, optionally,
c) et lim, og, eventuelt, c) an adhesive, and, optionally,
d) et stoff valgt blant polyakrylamider, polyetyleniminer, karboksymetylcellulose, urinstoff-formaldehydharpikser, d) a substance selected from polyacrylamides, polyethyleneimines, carboxymethylcellulose, urea-formaldehyde resins,
melamin-formaldehydharpikser, aminopolyamid-epiklorhydrinharpikser og polyamid-epiklorhydrinharpikser. melamine-formaldehyde resins, aminopolyamide-epichlorohydrin resins and polyamide-epichlorohydrin resins.
Suspensjonen som inneholder cellulosefibrene kan være rå-eller bleket masse, eller en blanding derav. Brukt papir og papp kan hyppig settes til blandingen. The suspension containing the cellulose fibers can be raw or bleached pulp, or a mixture thereof. Used paper and cardboard can often be added to the mix.
Den kationiske stivelse er en blanding av ett eller flere produkter som markedsføres under det generiske navn kationisk stivelse. Disse produkter er for eksempel de som er beskrevet i "KIRK-OTHMER", 3. utgave, vol. 21, s. 503. Mengden er fortrinnsvis mellom 0,5 og 5 deler pr. 100 deler cellulosefibre, fortrinnsvis mellom 0,7 og 2 deler. The cationic starch is a mixture of one or more products marketed under the generic name cationic starch. These products are, for example, those described in "KIRK-OTHMER", 3rd edition, vol. 21, p. 503. The quantity is preferably between 0.5 and 5 parts per 100 parts cellulose fibers, preferably between 0.7 and 2 parts.
Aluminiumpolyklorid antyder produkter som vanligvis henvises til som "aluminiumpolyklorid", "basisk aluminiumpolyklorid" og "basisk aluminiumpolyklorsulfat", og er fortrinnsvis ett eller flere av de følgende produkter: Aluminum polychloride refers to products commonly referred to as "aluminum polychloride", "basic aluminum polychloride" and "basic aluminum polychlorine sulphate", and is preferably one or more of the following products:

Dette produkt er beskrevet i FR-PS 2 584 699. This product is described in FR-PS 2 584 699.
Mengden aluminiumpolyklorid, uttrykt som AI2O3, som benyttes, er fortrinnsvis minst mindre enn 1 del pr. 100 deler cellulosefibre og fortrinnsvis mellom 0,02 og 0,3 deler. The amount of aluminum polychloride, expressed as AI2O3, which is used is preferably at least less than 1 part per 100 parts cellulose fibers and preferably between 0.02 and 0.3 parts.
Selv om det er mulig å tilsette produktene a) og b) i en hvilken som helst rekkefølge og på et hvilket som helst punkt før kassen i papirmaskinen, er det foretrukket å tilsette aluminiumpolykloridet efter den kationiske stivelse. Det er også å foretrekke at aluminiumpolykloridet tilsettes på et punkt så nær som mulig kassen. Although it is possible to add the products a) and b) in any order and at any point before the box in the paper machine, it is preferred to add the aluminum polychloride after the cationic starch. It is also preferable that the aluminum polychloride is added at a point as close as possible to the case.
Andre produkter som farvestoffer kan også settes til suspensjonen av cellulosefibre før tildanning av papirarket og i tillegg til produktene a) og b). Other products such as dyes can also be added to the suspension of cellulose fibers before forming the paper sheet and in addition to products a) and b).
I henhold til en annen utførelsesform av oppfinnelsen er det utover den kationiske stivelse mulig å tilsette ett eller flere produkter valgt blant polyakrylamider, polyetyleniminer, karboksymetylcellulose, urea-formaldehydharpikser, melamin-formaldehydharpikser, aminopolyamid-epiklorhydrinharpikser og polyamid-epiklorhydrinharpikser. Fortrinnsvis benyttes disse produkter i tillegg til kationisk stivelse og i de samme mengder. According to another embodiment of the invention, in addition to the cationic starch, it is possible to add one or more products selected from among polyacrylamides, polyethyleneimines, carboxymethylcellulose, urea-formaldehyde resins, melamine-formaldehyde resins, aminopolyamide-epichlorohydrin resins and polyamide-epichlorohydrin resins. Preferably, these products are used in addition to cationic starch and in the same quantities.
I henhold til en annen utførelsesform av oppfinnelsen er det også mulig i tillegg til produktene a) og b) eller i tillegg til de produkter som tilsettes med den kationiske stivelse slik som polyakrylamider og lignende som nevnt ovenfor, å tilsette et limingsmiddel for å gjøre papiret noe hydrofobt, noe som gjør at det motstår fuktighet. According to another embodiment of the invention, it is also possible in addition to the products a) and b) or in addition to the products that are added with the cationic starch such as polyacrylamides and the like as mentioned above, to add a sizing agent to make the paper somewhat hydrophobic, which means it resists moisture.
Selv om et hvilket som helst limmiddel er egnet, er det foretrukket å benytte kolofonium eller en blanding av ett eller flere produkter valgt blant dimere alkylketener og disses derivater, fluorerte fosfater, anhydrider av fett-kjedekarboksylsyrer, visse polyuretaner samt styren/malein-syreanhydridkopolymerer. Although any adhesive is suitable, it is preferred to use rosin or a mixture of one or more products selected from dimeric alkylketenes and their derivatives, fluorinated phosphates, anhydrides of fatty chain carboxylic acids, certain polyurethanes and styrene/maleic anhydride copolymers.
Det er foretrukket å benytte dimere alkylketener og karboksylsyreanhydrider. Mengden som benyttes avhenger av de egenskaper man ønsker i papiret eller pappen. Fortrinnsvis er mengden mindre enn 10 deler pr. 100 deler cellulosefibre og fortrinnsvis mellom 0,1 og 2 deler. It is preferred to use dimeric alkylketenes and carboxylic acid anhydrides. The amount used depends on the properties you want in the paper or cardboard. Preferably, the amount is less than 10 parts per 100 parts cellulose fibers and preferably between 0.1 and 2 parts.
Limet tilsettes fortrinnsvis før aluminiumpolyklorid tilsettes. The glue is preferably added before aluminum polychloride is added.
Vanlige additiver som farvestoffer og lignende kan også settes til suspensjonen før dannelse av papirarket. Common additives such as dyes and the like can also be added to the suspension before forming the paper sheet.
En annen fordel ved oppfinnelsen i tillegg til de gode oppnådde mekaniske egenskaper, er en sterk reduksjon av suspenderte stoffer i vannet som samles under wiren efter dannelse av arket. Another advantage of the invention, in addition to the good mechanical properties achieved, is a strong reduction of suspended substances in the water that collects under the wire after formation of the sheet.
Ytterligere en fordel ved oppfinnelsen er en større produk-tivitet på maskinen og en bedre indre kohesjon. Alle disse fordeler ville fremgå av eksemplene som skal illustrere oppfinnelsen. A further advantage of the invention is greater productivity on the machine and better internal cohesion. All these advantages would appear from the examples which will illustrate the invention.
