mer som forårsaker Fourdrinierwireslitasje. Mikroskopisk undersøkelse av slitte Fourdrinierwirer har vist at der er tallrike faktorer som innvirker på wirens levetid. En av de mest vanlige faktorer som for- more causing Fourdrinier wire wear. Microscopic examination of worn Fourdrinier wires has shown that there are numerous factors that affect the life of the wire. One of the most common factors that pre-

årsaker Fourdrinierwiresvikt er slipeslitasje forårsaket av en frik-sjon mellom bunnen på wiren og sugekassene, formebordene og avlederne. Det meste av denne slitasje inntreffer ved sugekassene. En alvorlig form for slipeslitasje består av graddannelse i bunnen på wirene, spesielt renningsleddene. I noen tilfeller utvikles tilstoppede steder i wirene. Dette kan mest alminnelig tilskrives dannelse av fremmed-legemér som er fastholdt i wiren. causes Fourdrinier wire failure is grinding wear caused by a friction between the bottom of the wire and the suction boxes, forming tables and diverters. Most of this wear occurs at the suction boxes. A serious form of grinding wear consists of burr formation at the bottom of the wires, especially the warp joints. In some cases, blocked places develop in the wires. This can most generally be attributed to the formation of foreign bodies that are retained in the wire.

Andre typer slitasje i Fourdrinierwirer kan tilskrives frik-sjonsvirkninger og viser seg som slitasje i form av hakk og forskyv-ninger. Ofte kan for stor wireslitasje tilskrives dårlige drenerings-egenskaper, enten på grunn av uriktig vakuum i sugekassene, eller andre tilsvarende grunner. Vann av dårlig kvalitet vil også forårsake avsetninger og gjentetning av masker i kantene. På grunn av wirens mekaniske egenskaper inntreffer ofte kantsprekker, kantsplitter og kantforskyvning. Other types of wear in Fourdrinierwirer can be attributed to frictional effects and shows up as wear in the form of notches and displacements. Excessive wire wear can often be attributed to poor drainage properties, either due to incorrect vacuum in the suction boxes, or other similar reasons. Poor quality water will also cause deposits and resealing of meshes at the edges. Due to the wire's mechanical properties, edge cracks, edge splits and edge displacement often occur.

En faktor som noen ganger fremskynder slipeslitasjen på Fourdrinierwirer, er korrosjon. I og for seg er korrosjon ikke spesielt ødeleggende for Fourdrinierwiren, men den vil i høy grad redusere wirens motstandsevne mot slipning og dreneringsegenskapene slik at friksjonsvirkningene som påføres wiren økes. One factor that sometimes accelerates grinding wear on Fourdrinierwirer is corrosion. In and of itself, corrosion is not particularly destructive to the Fourdrinier wire, but it will greatly reduce the wire's resistance to grinding and the drainage properties so that the frictional effects applied to the wire are increased.

Et nøyaktig studium av de ovenfor nevnte typer slitasje på en Fourdrinierwire får en fagmann til å trekke den åpenbare konklu-sjon at hvis slipeslitasje eller f riksj.onsegenskapene til Fourdrinierwire som er forårsaket av dens kontakt med de forskjellige deler og seksjoner anvendt i en Fourdriniermaskin kunne reduseres, og hvis dreneringsegenskapene til wiren kunne forbedres og derved hindre blokkering av enten fiber eller fremmedlegemer, så kunne en løsning på forlengelsen av Fourdrinierwirens levetid oppnås. Hvis derfor' en kjemisk behandling skal være.i stand til å forbedre operasjonsegen-skapene til en Fourdriniermaskin ved forlengelsen av brukstiden, må en slik behandling virke på to måter, dvs. den må være i stand til både å hindre slipeslitasje ved å gi en smørevirkning på wiren, og for det annet må den virke som et dispergerings- eller rensemiddel for å hindre eller fjerne avsetninger i wiremaskene. Hensikten med oppfinnelsen er derfor å tilveiebringe et rense- og smøremiddel som, når det anvendes i små økonomiske doser, vil forbedre driftseffektiviteten til en Fourdriniermaskin ved å hindre blokkeringen av wiremaskene av fremmedlegemer og cellulosefibre, og redusere slipeslitasjen. An accurate study of the above mentioned types of wear on a Fourdrinier wire leads one skilled in the art to draw the obvious conclusion that if the grinding wear or the frictional properties of the Fourdrinier wire caused by its contact with the various parts and sections used in a Fourdrinier machine could is reduced, and if the drainage properties of the wire could be improved and thereby prevent blockage of either fiber or foreign bodies, then a solution to extending the life of the Fourdrinier wire could be achieved. Therefore, if a chemical treatment is to be able to improve the operational characteristics of a Fourdrinier machine by extending the service life, such a treatment must work in two ways, i.e. it must be able to both prevent grinding wear by providing a lubricating effect on the wire, and secondly it must act as a dispersant or cleaning agent to prevent or remove deposits in the wire meshes. The object of the invention is therefore to provide a cleaning and lubricating agent which, when used in small economical doses, will improve the operating efficiency of a Fourdrinier machine by preventing the blocking of the wire meshes by foreign bodies and cellulose fibers, and reducing grinding wear.

Fra norsk patent nr. 10 3 69-0 er det kjent et preparat for slitasjenedsettende og anti-korroderende behandling av Fourdrinier-trådduker, og dette preparat består av vandige blandinger av 2-amino-etanol og et alkalimetalisalt av 2-merkaptobenzotiazol. Foreliggende middel har en kombinert smørende og rensende virkning hvor den rensende virkning tilveiebringes ved hjelp av spesielle organiske disper-geringsmidler og den smørende virkning tilveiebringes ved hjelp av en nitrogenholdig heterocyklisk forbindelse. Et slikt middel har en total virkning som er mer fordelaktig enn det tidligere kjente middel hvorved en behandling med det foreliggende middel blant annet tillater en lenger brukstid for wiren. Norwegian patent no. 10 3 69-0 discloses a preparation for wear-reducing and anti-corrosive treatment of Fourdrinier wire cloths, and this preparation consists of aqueous mixtures of 2-amino-ethanol and an alkali metal salt of 2-mercaptobenzothiazole. The present agent has a combined lubricating and cleansing effect, where the cleansing effect is provided by means of special organic dispersants and the lubricating effect is provided by means of a nitrogen-containing heterocyclic compound. Such an agent has an overall effect that is more advantageous than the previously known agent whereby a treatment with the present agent allows, among other things, a longer service life for the wire.

Ifølge foreliggende oppfinnelse er det således tilveiebragt et rense- og smøremiddel for anvendelse på returdelen på Fourdrinierwirer, omfattende en fortynnet vandig oppløsning av en blanding inneholdende en svovelholdig heterocyklisk forbindelse med den generelle formel: According to the present invention, there is thus provided a cleaning and lubricating agent for use on the return part of Fourdrinierwirer, comprising a diluted aqueous solution of a mixture containing a sulfur-containing heterocyclic compound with the general formula:

kjennetegnet ved at oppløsningen inneholder minst 2.3 g per tonn, basert på tørrvekten av papiret og papirproduktene dannet på Fourdrinierwiren, av (A) 5-98 vektprosent av et vannoppløselig, høy-trykks smøremiddel omfattende nevnte heterocykliske forbindelse, og (B) 2-95 vektprosent av et vann-blandbart, organisk, ikke-ionisk eller anionisk dispergeringsmiddel, og at den eventuelt også inneholder 0.01 - 5 vektprosent av en vanndispergerbar organisk silisiumholdig forbindelse. characterized in that the solution contains at least 2.3 g per ton, based on the dry weight of the paper and paper products formed on the Fourdrinier wire, of (A) 5-98 percent by weight of a water-soluble, high-pressure lubricant comprising said heterocyclic compound, and (B) 2-95 weight percent of a water-miscible, organic, non-ionic or anionic dispersant, and that it optionally also contains 0.01 - 5 weight percent of a water-dispersible organic silicon-containing compound.

Dette middel vil i alt vesentlig blir benyttet for behandling av Fourdrinierwirer hvor trådmaterialet består av fosfor-bronse. This agent will essentially be used for the treatment of Fourdrinier wires where the wire material consists of phosphor bronze.

De benyttede forbindelser har en dobbel virkning i og med at de gir smøring og forbedrer dreneringen av emnet som dannes og danner derved en overflate som har mindre tendens til å slippes enn en ubehandlet wire når den går over de forskjellige seksjoner til en typisk Fourdriniermaskin. Undersøkelser har ledet til den antagelse at lokaliserte områder med påkjenning er størst på de steder hvor det er høye trykk. Dette betyr at vanlige smøremidler har liten verdi når det gjelder å løse problemene som er nevnt ovenfor. For en mer inngående forståelse av hvorledes midlet ifølge oppfinnelsen anvendes til å forbedre driftsegenskapene til en Fourdriniermaskin, vises det til tegningen. The compounds used have a dual effect in that they provide lubrication and improve the drainage of the workpiece being formed, thereby creating a surface that has less tendency to drop than an untreated wire as it passes over the various sections of a typical Fourdrinier machine. Investigations have led to the assumption that localized areas of stress are greatest in places where there are high pressures. This means that ordinary lubricants are of little value in solving the problems mentioned above. For a more detailed understanding of how the agent according to the invention is used to improve the operating characteristics of a Fourdrinier machine, reference is made to the drawing.

Tegningen er et enkelt skjematisk diagram av en typisk Fourdrinierende på en papirfremstillingsmaskin. Tallene på tegningen representerer de forskjellige komponenter i Fourdriniersystemet. Det må forstås at tegningen er forenklet, men tjener til å illustrere hovedtrekkene i et typisk Fourdriniersystem. Innløpskassen og for-delingsområdet er i sin alminnelighet representert av henholdsvis tallene 1 og 2. Brystvalsen er illustrert av tallet 3 mens dekkel-valsene og formebordene er vist ved hjelp av tallene 4 og 5. Bord-valsen 6, trauet 7 og sugekassene 8 er en annen alminnelig gruppe komponenter som man finner i Fourdriniermaskiner. The drawing is a simple schematic diagram of a typical Fourdrinierende on a papermaking machine. The numbers in the drawing represent the different components of the Fourdrinier system. It must be understood that the drawing is simplified, but serves to illustrate the main features of a typical Fourdrinier system. The inlet box and the distribution area are generally represented by the numbers 1 and 2 respectively. The breast roll is illustrated by the number 3, while the cover rolls and the forming tables are shown using the numbers 4 and 5. The table roll 6, the trough 7 and the suction boxes 8 are another common group of components found in Fourdrinier machines.

Drivvalsene 9, dandyvalsen 10 og klumpknusevalsen 11 kan be-traktes som om de avslutter toppseksjonen på en typisk Fourdrinier-montering. Wiredusjene 12, vaskevalsene 13, automatiske styrevalser 14, strekkvalsene 15 og wirereturvalsene 16 og 16A danner alle hva som her. i sin alminnelighet er kalt returseksjonen på Fourdrinierwiren og arbeider for å kontrollere bunnbevegelsen på wiren. Selve wiren er indikert av tallet 18. En dusjanordning 17 er plasert mellom wire-returvalsen l6A og brystvalsen 3. Det er åpenbart at sprederen 17 bør være plasert slik at den sprer kjemikaliene ensartet på hele bredden til wiren 18 og den viste plasering er foretrukket. The drive rollers 9, the dandy roller 10 and the lump crusher roller 11 can be considered as terminating the top section of a typical Fourdrinier assembly. The wire showers 12, the washing rollers 13, the automatic guide rollers 14, the stretching rollers 15 and the wire return rollers 16 and 16A all form what here. in its generality is called the return section of the Fourdrinier wire and works to control the bottom movement of the wire. The wire itself is indicated by the number 18. A shower device 17 is placed between the wire return roller 16A and the breast roller 3. It is obvious that the spreader 17 should be positioned so that it spreads the chemicals uniformly over the entire width of the wire 18 and the location shown is preferred.

For at de skal være effektive er det ønskelig at kjemikaliene anvendes på returseksjonen på Fourdrinierwiren mellom driv-valsen 3 og dens etterfølgende kontaktpunkt med brystvalsen 9. Denne del av wiren er meget vel skikket for påføring av behandlingsmidlet. Det er å foretrekke at påføringspunktet er så nær brystvalsen som mulig. In order for them to be effective, it is desirable that the chemicals are used on the return section of the Fourdrinier wire between the drive roller 3 and its subsequent point of contact with the breast roller 9. This part of the wire is very well suited for applying the treatment agent. It is preferable that the point of application is as close to the chest roller as possible.

En alternativ måte for påføring av midlet ville være å på-føre det som et belegg ved en passende anordning (ikke vist) på wire-returvalsen 16, hvorved wirens returdel ville bli ensartet belagt. Uansett påføringsmetoden er det viktig at hele wiren 18 dekkes med kjemikaliene og at kjemikaliene påføres i form av en fortynnet vandig oppløsning. An alternative way of applying the agent would be to apply it as a coating by a suitable device (not shown) on the wire return roller 16, whereby the return part of the wire would be uniformly coated. Regardless of the application method, it is important that the entire wire 18 is covered with the chemicals and that the chemicals are applied in the form of a diluted aqueous solution.

Ut fra den ovenfor nevnte beskrivelse er det åpenbart at midlet ifølge oppfinnelsen fortrinnsvis påføres som en fortynnet van-'dig oppløsning på bunnen av wiren like før den kommer i kontakt med emnet som kommer inn fra innløpskassen 1 gjennom fordeleren 2. Denne påføring av en fortynnet vandig oppløsning kan fås i stand ved å opp-løse kjemikaliene i en passende vannkilde (ikke vist) og derved på-føre dem ved hjelp av vanntank eller spreder 17. Midlet kan tilberedes til å begynne med enten i tørr form som deretter blir fortynnet i papirfabrikken eller der den skal anvendes, eller de kan fremstilles som et vandig konsentrat for lett forsendelse til fabrikken hvor den kan fortynnes av maskinoperatørene. From the above-mentioned description, it is obvious that the agent according to the invention is preferably applied as a diluted aqueous solution to the bottom of the wire just before it comes into contact with the workpiece that enters from the inlet box 1 through the distributor 2. This application of a diluted aqueous solution can be obtained by dissolving the chemicals in a suitable water source (not shown) and thereby applying them using a water tank or spreader 17. The agent can be prepared initially either in dry form which is then diluted in the paper mill or where it is to be used, or they can be prepared as an aqueous concentrate for easy shipment to the mill where it can be diluted by the machine operators.

De vannoppløselige, høytrykks smøremidler er sulfhydryl-inneholdende forbindelser. De kan klassifiseres stort sett som nitro-genholdige heterocykliske forbindelser som erkarakterisert vedat et ring-nitrogen er bundet til et ringkarbon. Til ringkarbonet er knyt-tet en ikke-ringsulfhydrylgruppe., Den karakteristiske strukturformel som dekker denne sulfhydryl-heterocykliske kombinasjon av elementer kan illustreres ved hjelp av formel I nedenfor: The water-soluble, high-pressure lubricants are sulfhydryl-containing compounds. They can be broadly classified as nitrogen-containing heterocyclic compounds which are characterized by a ring nitrogen being bonded to a ring carbon. Attached to the ring carbon is a non-ring sulfhydryl group. The characteristic structural formula covering this sulfhydryl-heterocyclic combination of elements can be illustrated by formula I below:

Forbindelser som har denne illustrerende molekylkonfigurasjon er slike velkjente forbindelser som 2-merkaptotiazol, 2-merkaptobenzimidazol, 2-merkaptobenzoksazol og 2-merkaptobenzotiazol. Av disse forbindelser er 2-merkaptobenzotiazol foretrukket fordi den er relativt bil-lig og er kommersielt tilgjengelig. Compounds having this illustrative molecular configuration are such well-known compounds as 2-mercaptothiazole, 2-mercaptobenzimidazole, 2-mercaptobenzoxazole and 2-mercaptobenzothiazole. Of these compounds, 2-mercaptobenzothiazole is preferred because it is relatively inexpensive and is commercially available.

De ovenfor nevnte forbindelser er for praktiske formål relativt vannuoppløselige, men de kan lett gjøres oppløselige ved å om-danne dem til deres alkalimetallsalter. Hvilke som helst av de velkjente alkalimetallsalter til disse forbindelser f.eks. natrium, kalium, cesium og rubidium kan anvendes, skjønt natriumsaltene er foretrukket på grunn av deres tilgjengelighet og pris. Likeverdige med natriumsaltene til disse forbindelser er ammoniumsaltene, men de er ikke spesielt foretrukket på grunn av flytighetsproblemet som man støter på når maskinene arbeider med høye temperaturer. The above-mentioned compounds are for practical purposes relatively water-insoluble, but they can easily be made soluble by converting them to their alkali metal salts. Any of the well-known alkali metal salts of these compounds, e.g. sodium, potassium, cesium and rubidium can be used, although the sodium salts are preferred because of their availability and cost. Equivalent to the sodium salts of these compounds are the ammonium salts, but they are not particularly preferred because of the fluidity problem encountered when the machines operate at high temperatures.

De vannblandbare anioniske og ikke-ioniske dispergerings-midler som kan anvendes til å forbedre dreneringsegenskapene og derved forminske slitasjen på wiren, kan velges fra et stort antall av vel-, kjente kjemikalier. I tilfellet med de anioniske rensemidler kan de velkjente alkarylsulfonsyrer og deres alkalimetallsalter, slik som natriumdodecylbenzensulfonat anvendes såvel som alkalimetallsaltene av sulfonerte alkoholer og de sulfonerte ligniner. The water-miscible anionic and non-ionic dispersants which can be used to improve the drainage properties and thereby reduce wear on the wire, can be selected from a large number of well-known chemicals. In the case of the anionic cleaning agents, the well-known alkaryl sulfonic acids and their alkali metal salts, such as sodium dodecylbenzene sulfonate can be used as well as the alkali metal salts of sulfonated alcohols and the sulfonated lignins.

Skjønt anioniske fuktemidler kan anvendes er det å foretrekke at et ikke-ionisk fuktemiddel kombineres med det vannoppløs-bare høytrykks smøremidlet. Foretrukne ikke-ioniske materialer er de alkylsubstituerte etoksylerte fenoler som illustreres av strukturformel II.. Although anionic wetting agents can be used, it is preferable that a non-ionic wetting agent is combined with the water-soluble high-pressure lubricant. Preferred nonionic materials are the alkyl substituted ethoxylated phenols illustrated by structural formula II.

I formelen ovenfor er R en alkylgruppe med fra 8 til 20 karbonatomer og n et helt tall som har en verdi på- høyst 20. En forbindelse som faller innenfor denne gruppe er dodecylfenol som er omsatt med 9 mol etylenoksyd. In the formula above, R is an alkyl group with from 8 to 20 carbon atoms and n is an integer that has a value of at most 20. A compound that falls within this group is dodecylphenol which has been reacted with 9 mol of ethylene oxide.

Andre egnede ikke-ioniske fuktemidler er de velkjente "Pluronic" materialene som er blokk-kopolymere av propylen- og etylenoksyd og er beskrevet i US patent nr. 2 .674 619. Other suitable nonionic wetting agents are the well-known "Pluronic" materials which are block copolymers of propylene and ethylene oxide and are described in US Patent No. 2,674,619.

For en mer omfattende og detaljert liste over forskjellige ikke-ioniske og anioniske fuktemidler som kan anvendes vises det til "Detergents and Emulsifiers to Date" av John W. McCutcheon, John W. McCutcheon, Inc., 1960. For a more extensive and detailed list of various nonionic and anionic wetting agents that may be used, see "Detergents and Emulsifiers to Date" by John W. McCutcheon, John W. McCutcheon, Inc., 1960.

Under behandling av Fourdrinierwiren for å gi øket varighet under dens normale operasjon, tilføres midlet i en relativt lav dose, f.eks. 2.37 g per tonn basert på tørrvekten av papiret som er laget på Fourdrinierwiren med den valgte dose mellom fra 11.4 til 45.4 g per tonn. During treatment of the Fourdrinier wire to give increased duration during its normal operation, the agent is added in a relatively low dose, e.g. 2.37 g per tonne based on the dry weight of the paper made on the Fourdrinier wire with the selected dose between 11.4 to 45.4 g per tonne.

Fuktemidlene og de vanndispergerbare høytrykks-smøremidlene kombineres slik at de gir en sammensetning som inneholder fra 5 til 98 vektprosent av det vannoppløsbare høytrykks smøremidlet og fra 2 til 95 vektprosent av det vannblandbare ikke-ioniske eller anioniske dis-pergeringsmidlet. The wetting agents and the water dispersible high pressure lubricants are combined to provide a composition containing from 5 to 98 percent by weight of the water soluble high pressure lubricant and from 2 to 95 percent by weight of the water miscible nonionic or anionic dispersant.

Egenskapene til de to bestanddelene kan selvfølgelig variere, avhengig av de spesielle forhold ved Fourdriniermaskinen og wiren som skal behandles. For eksempel, hvis det er fastslått av slipnings-slitasjen i høy grad kommer av gjenstopping av maskeåpningene i wiren, vil det være ønskelig at det anvendes en større mengde av overflate- aktivt middel, mens hvis slipningsslitasje er et fremherskende pro-blem så bør mengden av vannoppløsbart høytrykks smøremiddel økes. The properties of the two components can of course vary, depending on the particular conditions of the Fourdrinier machine and the wire to be processed. For example, if it has been established that the grinding wear is to a large extent caused by plugging of the mesh openings in the wire, it will be desirable that a larger amount of surface-active agent is used, while if grinding wear is a predominant problem then the amount should of water-soluble high-pressure lubricant is increased.

Rensemidlet ifølge oppfinnelsen kan enten formuleres somThe cleaning agent according to the invention can either be formulated as

en tørr blanding og så oppløses på anvendelsesstedet eller fortrinnsvis tilberedes de som et vandig konsentrat som så utblandes til bruks-konsentrasjon. a dry mixture and then dissolved at the point of use or preferably they are prepared as an aqueous concentrate which is then diluted to a concentration for use.

En typisk sammensetning som er hensiktsmessig er følgende A typical composition that is appropriate is the following

vandige konsentrat:aqueous concentrate:

Skjønt produkter av typen som er illustrert ovenfor har vært meget gode med hensyn til å forbedre arbeidsegenskapene til Fourdriniermaskiner, har det også blitt oppdaget at midlet kan forbedres når det gjelder virkningsgrad, spesielt i tilfeller hvor sugekassefrik-sjonen er meget stor, ved å innarbeide i fra 0.001 til 0.5 vektprosent av en vanndispergerbar organisk silisiumholdig forbindelse. Although products of the type illustrated above have been very good in improving the working characteristics of Fourdrinier machines, it has also been discovered that the agent can be improved in terms of efficiency, particularly in cases where suction box friction is very high, by incorporating in from 0.001 to 0.5 percent by weight of a water-dispersible organosilicon-containing compound.

De silisiumholdige forbindelser kan være av to hovedtyper, den første er et organisk silisiumoksyd kondensasjonsprodukt som omfatter slike velkjente produkter som de kondenserte estere av orto-og metakiselsyre og de velkjente silisiumpolymere slik som polydimetyl-siloksaner. Produkter av denne hovedtype er beskrevet i detalj i US The silicon-containing compounds can be of two main types, the first is an organic silicon oxide condensation product which includes such well-known products as the condensed esters of ortho- and metasilicic acid and the well-known silicon polymers such as polydimethyl siloxanes. Products of this main type are described in detail in US

2 4l6 503-4. Når silisiumholdige forbindelser av denne type anvendes, er det viktig at de i det minste kolloidalt er dispergerbare i vann. Når forbindelsene ikke er dispergerbare i seg selv, er det mulig å bringe dem til en tilstrekkelig oppdelt tilstand f.eks. en mikron eller mindre, for derved å gjøre det mulig kolloidalt å dispergere slike silisiumholdige forbindelser i vannet. En foretrukken gruppe silisiumholdige forbindelser er de organisk funksjonelle silaner med den generelle formel III: 2 4l6 503-4. When silicon-containing compounds of this type are used, it is important that they are at least colloidally dispersible in water. When the compounds are not dispersible in themselves, it is possible to bring them to a sufficiently divided state, e.g. a micron or less, thereby making it possible to colloidally disperse such silicon-containing compounds in the water. A preferred group of silicon-containing compounds are the organically functional silanes of the general formula III:

I formelen ovenfor er R en lavere alifatisk hydrokarbon-gruppe med høyst 4 karbonatomer i kjeden. Y er en alifatisk aminholdig gruppe og n = 0 eller 1. Typiske eksempler på forbindelser som kommer innenfor strukturformelen ovenfor er gamma-aminpropyltrietoksysilan, delta-aminobutylmetyl-dietoksysilan og 2-(3-trimetoksysilylpropylamin)-etylamin. De ovenfor nevnte vanndispergerbare organiske silisium-holdige forbindelser har ikke bare en tendens til å forbedre smøre-egenskapene til rensemidlet, men de virker også i noen tilfeller som skumhindrende middel til å hindre overdreven skumdannelse i det punkt hvor formelen påføres. In the formula above, R is a lower aliphatic hydrocarbon group with at most 4 carbon atoms in the chain. Y is an aliphatic amine-containing group and n = 0 or 1. Typical examples of compounds that come within the structural formula above are gamma-aminopropyltriethoxysilane, delta-aminobutylmethyl-diethoxysilane and 2-(3-trimethoxysilylpropylamine)-ethylamine. The aforementioned water-dispersible organic silicon-containing compounds not only tend to improve the lubricating properties of the cleanser, but they also act in some cases as anti-foam agents to prevent excessive foaming at the point where the formula is applied.

Følgende eksempler illustrerer oppfinnelsen.The following examples illustrate the invention.

Eksempel IExample I

Dette forsøk ble utført i en papirfabrikk som fremstilte ub leket kraftforingsplater på en Fourdriniermaskinwire med arbeidB-hastigheter mellom 152.5 og 411.75 m per minutt. Fourdrinierwiren hadde en levetid på mellom 8 og 10 dager. Inspeksjon av wiren indi-kerte at slipningsødeleggelse inntraff på grunn av passasjen av wiren over sugekassene. Det ovenfor angitte konsentrat ble sprøytet på wiren ved hjelp av et spredehode plasert mellom brystvalsen og bord-valsen, idet dosene ble startet opprinnelig med 68.1 g per tonn i flere timer og så ble redusert til 45.4 g per tonn. Ved slutten av flere måneders prøve var det åpenbart at wirelevetiden var drastisk øket. Noen omganger tillot en maskin å arbeide i 20 dager med den korteste wirelivstid på 12 dager. Inspeksjon av wiren viste alltid at den var ren med lite eller ingen tilstopping med enten cellulose-materiale eller fremmedlegemer av noen sort. This experiment was carried out in a paper mill which produced unbleached kraft liner plates on a Fourdrinier machine wire at working speeds between 152.5 and 411.75 m per minute. The Fourdrinier wire had a lifespan of between 8 and 10 days. Inspection of the wire indicated that grinding damage occurred due to the passage of the wire over the suction boxes. The above-mentioned concentrate was sprayed onto the wire by means of a spreading head placed between the breast roller and the table roller, the doses initially starting at 68.1 g per tonne for several hours and then being reduced to 45.4 g per tonne. At the end of several months of testing, it was obvious that the wire life had been drastically increased. Some rounds allowed a machine to work for 20 days with the shortest wire life of 12 days. Inspection of the wire always showed it to be clean with little or no clogging with either cellulosic material or foreign matter of any kind.

Eksempel IIExample II

I en papirfabrikk fremstilte en maskin ubleket kraftpappIn a paper mill, a machine produced unbleached kraft paperboard

og papir med en hastighet på 366 til 640.5 ni i minuttet. Normal wire-levetid ved denne fabrikk var gjennomsnittlig f. 5 dager. Det ovenfor angitte konsentrat ble påført wirens returdel ved hjelp av en spreder som var plasert nær brystvalsen med en dose som gikk fra mellom 36.32 and paper at a speed of 366 to 640.5 ni per minute. Normal wire life at this factory was an average of 5 days. The above-mentioned concentrate was applied to the return part of the wire by means of a spreader placed near the breast roller with a dose ranging from between 36.32

g til 113.6 g per 907.2 kg. Prøven strakte seg over flere måneder og på slutten av denne tid ble det beregnet at wirens varighet var for-lenget til et gjennomsnitt på 10 1/3 dag. Dette er selvfølgelig en anseelig forøkning i forhold til gjennomsnittet for den opprinnelige varighet som man hadde før behandlingen. Behandlingen forbedret og holdt dreneringsegenskapene over dreneringen som man oppnådde på en g to 113.6 g per 907.2 kg. The test extended over several months and at the end of this time it was calculated that the duration of the wire had been extended to an average of 10 1/3 days. This is of course a considerable increase compared to the average for the original duration that one had before the treatment. The treatment improved and maintained the drainage properties above the drainage achieved on one

wire ved starten av prøven. Eksemplet ovenfor illustrerer at dose-størrelsene kan varieres. Erfaring og virkelige papirfabrikkforhold har vist at det er ønskelig å innledningsvis forbehandle wiren ved å påføre over en kort tidsperiode f.eks. flere timer til. flere dager, noe større dose som så reduseres til en minimumsmengde. Således ville det i et typisk papirfabrikksystem være ønskelig å behandle med 113.6 g per tonn med en sammensetning som nevnte konsentrat i flere timer og så holde en dose på 45.4 g per tonn. Dette gjør det mulig for et beskyttende lag av fuktemidlet og et vannoppløselig høytrykkssmøre-middel, i tilstrekkelig grad å belegge wiren og å gi en smøremiddel-basis på wiren som så opprettholdes ved den etterfølgende kontinuer-lige dose. Det er mulig å mate behandlingsmidlene i mengder avbrutt med mellomrom på wirens returdel, men det er en foretrukket praksis at den kjemiske behandling holdes kontinuerlig gjennom hele wirens levetid for å oppnå maksimal varighet. wire at the start of the test. The example above illustrates that the dose sizes can be varied. Experience and real paper mill conditions have shown that it is desirable to initially pre-treat the wire by applying over a short period of time e.g. several more hours. several days, somewhat larger dose which is then reduced to a minimum amount. Thus, in a typical paper mill system, it would be desirable to treat with 113.6 g per ton with a composition such as said concentrate for several hours and then maintain a dose of 45.4 g per ton. This enables a protective layer of the wetting agent and a water soluble high pressure lubricant to sufficiently coat the wire and to provide a lubricant base on the wire which is then maintained by the subsequent continuous dose. It is possible to feed the treatment agents in quantities interrupted at intervals on the return part of the wire, but it is a preferred practice that the chemical treatment is kept continuous throughout the life of the wire to achieve maximum duration.

Som vist ovenfor er et viktig resultat oppnådd ved å anvende foreliggende rensemiddel, nemlig den store forbedring som oppnås i dreneringen av emnene som dannes på de ubehandlede wirer. Denne virkning tillater at en bedre papirkvalitet fremstilles samt hurtigere tørking og flakdannelse. Oppfinnelsen tillater også at det anvendes større variasjoner i raffinerings- og maskinhastigheter. As shown above, an important result has been achieved by using the present cleaning agent, namely the great improvement achieved in the drainage of the blanks formed on the untreated wires. This effect allows a better paper quality to be produced as well as faster drying and flake formation. The invention also allows greater variations in refining and machine speeds to be used.
