Mere spesielt vedrorer oppfinnelsen et cellulosefibermateriale, hvor der på overflaten er påfort et limingsmateriale under sure, nbytrale eller alkaliske pH-betingelser under forhold soir. er forenbare med vanlige papirf remstillingsmetoder. The present invention relates to a cellulose fiber material. More particularly, the invention relates to a cellulose fiber material, where a gluing material has been applied to the surface under acidic, neutral or alkaline pH conditions under conditions soir. are compatible with common papermaking methods.
Oppfinnelsen består hovedsakelig i at der på cellulosefibermate-rialets overflate er påfort et limingsmiddel bestående av en kombinasjon av (a) en forbindelse med formel hvor R betegner alkyl med 10-^0 karbonatomer, alkenyl med 10-^t-O karbonatomer eller alkylfenyl med minst 8 karbonatomer i hver alkylgruppe, eventuelt inneholdende inerte substituenter, slike som karboalkoksy, alkyloksy, aryloksy, aryloalkyloksy, keto(kar-bonyl), tertiært amid, halogen bundet til aromatiske karboner og The invention mainly consists in the fact that an adhesive consisting of a combination of (a) a compound of formula where R denotes alkyl with 10-^0 carbon atoms, alkenyl with 10-^t-0 carbon atoms or alkylphenyl with at least 8 is applied to the surface of the cellulose fiber material carbon atoms in each alkyl group, optionally containing inert substituents, such as carboalkoxy, alkyloxy, aryloxy, arylalkyloxy, keto(carbonyl), tertiary amide, halogen bonded to aromatic carbons and
R' er hydrogen, metyl eller klormetyl ogR' is hydrogen, methyl or chloromethyl and
n er en indeks fra 0 til 2, ogn is an index from 0 to 2, and
(b)' et polyalkylenimin med fra 2 til 3 karbonatomer i alkylengruppene, idet de forenede mengder av (a) og (b) er minst 0,1 vektsf av de torre cellulosefibrene, og vektsforholdene mellom (a) og (b) er fra 1:10 til 10:1. (b)' a polyalkylene imine with from 2 to 3 carbon atoms in the alkylene groups, the combined amounts of (a) and (b) being at least 0.1 by weight of the dry cellulose fibers, and the weight ratios between (a) and (b) being from 1:10 to 10:1.
Denne kombinasjon av 2-kloralkyl-sulfon-sulfoksyd eller -sulfid og polyalkyleniminet kan påfores ved enhver egnet metode kjent for fagmannen på limningsområdet. De kan forenes til en opplosning eller dispersjon og tilsettes til en vandig fibros oppslemning eller masseoppslemning, eller de kan også påfores ved overflatelimningsmetoder ved å fore celluloseholdig bane eller tekstiler gjennom opplosninger av de forenede ingredienser eller gjennom separate opplosninger av de to komponenter for å forårsake kontakt av cellulosefibermaterialet med både 2-kloralkyl-svovelforbindelse og polyalkyleniminet. Et foretrukket eksempel for påforingen er å tilsette til den vandige masseoppslemning som anvendes for å fremstille celluloseholdig papir, enten separat eller i kombinasjon et hoyere alkyl-2-kloretyl- eller 2,3-diklorpropylsulfon og et polyetylenimin, hvor de forenede mengder av de to komponenter er mellom 0,1 og 5»0 vektsf av den torre massefiber i masseoppslemningen som behandles, skjbnt totale prosentuelle mengder kan være fra 0,1$ til en hoyere mengde som dikteres av omkostningene. De to komponenter er for-trinnsvis forenet i vektsforhold på 1:1 til 1:3 mellom 2-kloralkyl-hydrofobsulfon, polyetylenimin, skjont egnede vektsforhold- mengder kan variere fra 1:10 til 10:1 og fremdeles gi en limende virkning. Et minimum på ca. 0,2$ av hver komponent skal brukes for effektiv liming. 2-bromalkylsulfider, -sulfoksyder og This combination of 2-chloroalkyl sulfone sulfoxide or sulfide and the polyalkylene imine can be applied by any suitable method known to those skilled in the art of bonding. They may be combined into a solution or dispersion and added to an aqueous fibrous slurry or pulp slurry, or they may also be applied by surface bonding methods by passing cellulosic webs or textiles through solutions of the combined ingredients or through separate solutions of the two components to cause contact of the cellulose fiber material with both the 2-chloroalkyl sulfur compound and the polyalkylenimine. A preferred example for the application is to add to the aqueous pulp slurry used to produce cellulosic paper, either separately or in combination, a higher alkyl-2-chloroethyl- or 2,3-dichloropropyl sulfone and a polyethyleneimine, where the combined amounts of the two components are between 0.1 and 5% by weight of the dry pulp fiber in the pulp slurry being treated, although total percentage amounts may be from 0.1 to a higher amount as dictated by cost. The two components are preferably combined in a weight ratio of 1:1 to 1:3 between 2-chloroalkylhydrophobesulfone, polyethyleneimine, although suitable weight ratio amounts can vary from 1:10 to 10:1 and still provide an adhesive effect. A minimum of approx. 0.2$ of each component should be used for effective bonding. 2-bromoalkyl sulfides, -sulfoxides and
-sulfoner kan også brukes, hvis onsket.-sulfones can also be used, if desired.
Virkningen av denne spesielle kombinasjon av et 2-kloralkylsulfon, sulfoksyd og sulfid og et polyalkylenimin er helt uventet, fordi kombinasjon av beslektede materialer, slik som 2-hydroksyetyl-octadecylsulfon med polyetylenimin og påfort på en måte lignende påforingen av 2-kloretyl-octadecylsulfon og polyetylenimin ga i det vesentlige ingen liming. Det er imidlertid blitt funnet at 2,3-diklorpropyl-hydrofob-hydrocarbonsulfider og sulfoksyder kan brukes for å forårsake liming i overensstemmelse med nærværende oppfinnelse eller erstatte helt eller delvis det tilsvarende sulfon av limningskombinasjonen, men sulfonet er foretrukket fordi det er mer effektivt i denne kombinasjon. 2,3-diklorpropyl-hydrofobsulfid er langt mer effektivt i limningsblandingen enn 2-kloretyl-hydrofobsulfidet er. Når 2-kloralkylsulfider og sulfoksyder brukes, er det imidlertid vanligvis nodvendig å herde det behandlede cellulosematerialet, f.eks. ved 105° C i en time for å forårsake liming. De.tilsvarende sulfoner i denne kombinasjon bevirker liming uten et langvarig herdningstrinn og folgelig er sulfonene foretrukket. The effect of this particular combination of a 2-chloroalkylsulfone, sulfoxide and sulfide and a polyalkylenimine is completely unexpected, because combining related materials, such as 2-hydroxyethyl octadecyl sulfone with polyethyleneimine and proceeding in a similar manner to the application of 2-chloroethyl octadecyl sulfone and polyethyleneimine produced essentially no bonding. However, it has been found that 2,3-dichloropropyl hydrophobic hydrocarbon sulfides and sulfoxides can be used to cause sizing in accordance with the present invention or replace in whole or in part the corresponding sulfone of the sizing combination, but the sulfone is preferred because it is more effective in this combination. 2,3-dichloropropyl hydrophobic sulfide is far more effective in the sizing mixture than 2-chloroethyl hydrophobic sulfide is. However, when 2-chloroalkyl sulfides and sulfoxides are used, it is usually necessary to cure the treated cellulosic material, e.g. at 105° C for one hour to cause bonding. The corresponding sulphones in this combination effect gluing without a prolonged curing step and consequently the sulphones are preferred.
2-kloralkyl-hydrofobsulfidene, sulfoksydene og sulfonene som er funnet å være anvendelige for liming av cellulosefiber-materialer, omfatter de i hvilke hydrofobgruppen er et hoyere alkyl med minst 10 karbonatomer, f.eks. decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, heksadecyl, heptadecyl, octadecyl, tetracosyl og pentacosyl og hoyere alkyl opp til ^0 karbonatomer, hvis onsket, skjont de med fra 25 karbonatomer er foretrukket, The 2-chloroalkyl hydrophobic sulphides, sulphoxides and sulphones found to be useful for sizing cellulosic fiber materials include those in which the hydrophobic group is a higher alkyl of at least 10 carbon atoms, e.g. decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, tetracosyl and pentacosyl and higher alkyl up to ^0 carbon atoms, if desired, although those with from 25 carbon atoms are preferred,
de tilsvarende alkenylgrupper med 10 til h0 karbonatomer og noen eksempler på disse er decenyl, tridecenyl, heptadecenyl, octa-decenyl, eicosenyl, tricosenyl, osv. alkylfenyl og alkylsubsti-tuert cykloalkyl med minst 8 karbonatomer i alkylgruppene som er bundet til fenyl eller cykloalkylgruppen,. f.eks. octylfenyl, dinonylfenyl, dodecylfenyl, tridecylfenyl, pentadecylfenyl, octadecylfenyl, heneicosylfenyl, nonylcyklopropyl, dodecylcyklo-butyl, tridecylcyklopentyl, tetradecylcykloheksyl, pentadecyl- the corresponding alkenyl groups with 10 to h0 carbon atoms and some examples of these are decenyl, tridecenyl, heptadecenyl, octa-decenyl, eicosenyl, tricosenyl, etc. alkylphenyl and alkyl-substituted cycloalkyl with at least 8 carbon atoms in the alkyl groups which are attached to the phenyl or cycloalkyl group, . e.g. octylphenyl, dinonylphenyl, dodecylphenyl, tridecylphenyl, pentadecylphenyl, octadecylphenyl, heneicosylphenyl, nonylcyclopropyl, dodecylcyclo-butyl, tridecylcyclopentyl, tetradecylcyclohexyl, pentadecyl-
cykloheptyl, octadecyl.cykloheksyl etc, og slike som alkyl, alkenyl, alkylfenyl og alkylcykloalkyl, 2-kloralkylsulfid, cycloheptyl, octadecyl.cyclohexyl etc, and such as alkyl, alkenyl, alkylphenyl and alkylcycloalkyl, 2-chloroalkyl sulphide,
sulfoksyd eller sulfonforbindelser som ikke inneholder noen for-styrrende inerte substituenter. Inerte substituenter som kan være til stede omfatter grupper, slike som karboalkoksy, alkyloksy, aryloksy, arylalkyloksy, keto(carbonyl), tertiært amid, halogen bundet til aromatiske karboner eller alifatiske heterocykliske grupper, dvs. heterocykliske radikaler som ikke inneholder noen umettet benzen. Det heterocykliske radikal kan være mettet eller umettet. Typer på radikaler som ikke skal være til stede i noen vesentlig grad i den hydrofobe gruppe eksemplifise-res av hydroksylgrupper, primære og sekundære aminogrupper, sulfoxide or sulfone compounds which do not contain any interfering inert substituents. Inert substituents which may be present include groups, such as carboalkoxy, alkyloxy, aryloxy, arylalkyloxy, keto(carbonyl), tertiary amide, halogen bonded to aromatic carbons or aliphatic heterocyclic groups, i.e. heterocyclic radicals containing no unsaturated benzene. The heterocyclic radical can be saturated or unsaturated. Types of radicals which should not be present to any significant extent in the hydrophobic group are exemplified by hydroxyl groups, primary and secondary amino groups,
labile halogener, amidgrupper med amidohydrogen og karboksyl eller andre sure grupper. Fagmannen på området vil være klar over arter av hydrofobgrupper som kan brukes i disse 2-kloralkyl-sulf id, sulfoksyder og sulfon-forbindelser, hvis uonskede bi-reaksjoner skal unngås. labile halogens, amide groups with amidohydrogen and carboxyl or other acidic groups. Those skilled in the art will be aware of species of hydrophobic groups that can be used in these 2-chloroalkyl sulfide, sulfoxides and sulfone compounds, if undesired side reactions are to be avoided.
Disse sulfid, sulfoksyd og sulfonforbindelser kan brukes som enkelte rene forbindelser for oppfinnelsens formål. Imidlertid ved vanlig praksis, 2-kloralkylsulfid, sulfoksyd og sulfonforbindelser som inneholder f.eks. blandet hydrofobalkyl, blandet alkenyl og alkyl, alkylfenyl eller alkyl og alkylsubstituerte cykloalkylgrupper kan hensiktsmessig anvendes. Blandinger som sulfider, sulfoksyder og sulfoner er også anvendelige. These sulfide, sulfoxide and sulfone compounds can be used as individual pure compounds for the purposes of the invention. However, in common practice, 2-chloroalkyl sulfide, sulfoxide and sulfone compounds containing e.g. mixed hydrophobic alkyl, mixed alkenyl and alkyl, alkylphenyl or alkyl and alkyl-substituted cycloalkyl groups can suitably be used. Mixtures such as sulphides, sulphoxides and sulphones are also useful.
For noen anvendelser av disse materialkombinasjoner på noen cellulosefibrose materialer iakttas oket limningsvirkning når disse 2-kloralkylsulfid, sulfoksyd og sulfoner påfores til fibrost substrat blandet med eller samtidig med et basisk materiale, slik som et alkalimetallhydroksyd i en mengde tilstrekkelig til å bevirke limning på den basiske'side i pH-området, dvs. over pH 7 enten for eller samtidig med tilsetningen av polyetyleniminet. Når denne metode anvendes, vil basen som anvendes vanligvis være natriumhydroksyd, fordi den er den lettest til-gjengelige og den mest okonomiske å bruke. Imidlertid skal det forstås at andre basiske materialer, slik som kaliumhydroksyd, kalk, hydratisert kalk, kalsiumhydroksyd og andre alkalimetaller og jordalkalimetallbaser og basiske salter kan brukes, hvis onsket. Fra tysk patent nr. 1 155 666 er det kjent en fremgangsmåte for fremstilling av sugedyktige og vannmotstandsdyktige vevnader av cellulosefibre, hvor der på fibrene i oppslemning påfores en blanding av herdbare i og for seg kjente kunstharpikser eventuelt i forbindelse med vanlige fyll-, farge- og kondisjoneringsmidler, hvilken fremgangsmåte omfatter epoksydharpikser og 10-50 mol$ For some applications of these material combinations on some cellulosic fibrous materials, increased gluing action is observed when these 2-chloroalkyl sulfide, sulfoxide and sulfones are applied to the fibrous substrate mixed with or simultaneously with a basic material, such as an alkali metal hydroxide in an amount sufficient to effect gluing on the basic side in the pH range, i.e. above pH 7 either before or simultaneously with the addition of the polyethyleneimine. When this method is used, the base used will usually be sodium hydroxide, because it is the most readily available and the most economical to use. However, it should be understood that other basic materials, such as potassium hydroxide, lime, hydrated lime, calcium hydroxide and other alkali metal and alkaline earth metal bases and basic salts may be used, if desired. From German patent no. 1 155 666, a method is known for the production of absorbent and water-resistant woven fabrics of cellulose fibres, where a mixture of hardenable synthetic resins known per se is applied to the fibers in a slurry, possibly in connection with usual fillers, dyes and conditioning agents, which method comprises epoxy resins and 10-50 mol$
av dimetylol-ureaharpikser, guanidinformaldehydharpikser eller pentametyleniminer. Anvendelse av polyetyleniminer i limings-kombinasjoner er her kjent, men ikke i den patentanmeldte kombinasjon og ikke .med den effekt som fremgår av nedenstående beskrivelse. of dimethylol urea resins, guanidine formaldehyde resins or pentamethylene imines. The use of polyethylene imines in bonding combinations is known here, but not in the patent pending combination and not with the effect that appears from the description below.
Kombinasjonen av sulfid, sulfoksyd og sulfonmaterialer og polyetylenimin kan påfores de fibrose substrater for å lime disse på vanlig måte. Det fibrose materiale i form av cellulosemasse, ferdig papirark eller papirprodukt, tekstilfiber, trå, garn eller stoffer kan være enkelt dyppet i en opplosning av et med vann ikke blandbart organisk opplosningsmiddel av 2-kloralkylsulfid, sulfoksyd eller sulfon og derpå i en. opplosning av polyetyleniminet og deretter torres. Uttrykket "torring" og de tilsvarende adjektiv, verb og partisippformer anvendes her for å inkludere herdning av det behandlede fibrose substrat for å gi et ferdiglimt fibrost produkt. Mengden av 2-kloralkylsulfidet, sulfoksydet eller sulfonet og polyetyleniminet som holdes til-bake av det fibrose materiale kan reguleres ved konsentrasjon av behandlingsopplosningen og graden av vridning eller pressing av det dyppede fibrose materiale for torring. The combination of sulphide, sulphoxide and sulphone materials and polyethyleneimine can be applied to the fibrous substrates to bond them in the usual way. The fibrous material in the form of cellulose pulp, finished paper sheet or paper product, textile fiber, thread, yarn or substances can be simply dipped in a solution of a water-immiscible organic solvent of 2-chloroalkyl sulphide, sulphoxide or sulphone and then in a. dissolution of the polyethyleneimine and then dried. The term "drying" and the corresponding adjective, verb and participle forms are used herein to include curing the treated fibrous substrate to provide a pre-bonded fibrous product. The amount of the 2-chloroalkyl sulfide, sulfoxide or sulfone and polyethyleneimine retained by the fibrous material can be controlled by concentration of the treatment solution and the degree of twisting or pressing of the dipped fibrous material for drying.
Oppfinnelsen omfatter også bruken av denne kombinasjon av limingsmaterialer i forbindelse, med midler bestemt for å oke tilbakeholdelsen av de limende midler på det fibrose substrat, slik som cellulosefibre. Anvendelige hjelpemidler av denne art omfatter kationisk stivelse og et godt eksempel på denne er en modifisert maisstivelse som har et nitrogen-innhold på ca. 0,25$ og som selges under varemerke "Cato 8" av National Starch Products Company. Når fra 0,1 til ca. 0,5 vekts$ basert på vekten av det fibrose substrat, f.eks. cellulosemasse, av en kationisk stivelse, slik som "Cato 8" tilsettes til masseoppslemningen for, etter eller samtidig med limningsmidlet, oppnås en avgjort forbedring i tilbakeholdelsen av limningsmidlet. The invention also includes the use of this combination of adhesive materials in conjunction with agents intended to increase the retention of the adhesive agents on the fibrous substrate, such as cellulose fibers. Useful aids of this kind include cationic starch and a good example of this is a modified maize starch which has a nitrogen content of approx. 0.25$ and which is sold under the trademark "Cato 8" by the National Starch Products Company. When from 0.1 to approx. 0.5 wt based on the weight of the fibrous substrate, e.g. cellulose pulp, of a cationic starch, such as "Cato 8" is added to the pulp slurry before, after or at the same time as the sizing agent, a decided improvement in retention of the sizing agent is achieved.
Polyalkyleniminene som anvendes ved nærværende oppfinnelse er polymerisasjonsprodukter av etylenimin eller derivater av dette. De som anvendes ved oppfinnelsen er de som har fra 2 til 3 karbonatomer i hver alkylengruppe som er vannopploselig. Slike pro-dukter er f.eks. beskrevet i U.S. patent nr. 2 192 306. Poly(N-metylalkyleniminene) som også kan brukes er polymerisasjons-produktene av N-metyl-etylenimin, N-metylpropylenimin eller blandinger av disse. The polyalkylenimines used in the present invention are polymerization products of ethyleneimine or derivatives thereof. Those used in the invention are those which have from 2 to 3 carbon atoms in each alkylene group which are water soluble. Such products are e.g. described in the U.S. patent no. 2 192 306.

De folgende eksempler vil ytterligere illustrere oppfinnelsen, The following examples will further illustrate the invention,
EKSEMPEL 1EXAMPLE 1
Dette eksempel illustrerer den vesentlige okede limningseffektivitet som oppnås ved å bruke kombinasjonen av polyetyleniminet og et 2-kloretylsulfon av den art som nærværende oppfinnelse foreskriver i sammenligning med et 2-hydroksyetylsulfon. This example illustrates the substantially increased bonding efficiency obtained by using the combination of the polyethylene imine and a 2-chloroethyl sulfone of the kind prescribed by the present invention in comparison with a 2-hydroxyethyl sulfone.
I dette eksempel ble polyetylenimin tilsatt til en 2% papir-masseoppslemning i vann i en mengde lik 1% basert på torrvekten og rort om i 15 minutter, og derpå ble 1$, basert på vekten av massen,av enten 2-kloretyloctadecylsulfon som en opplosning i p-cymen tilsatt, hvilke ble emulgert i vann ved bruk av heksa-decyltrimetyl-ammoniumbromid (Arquad) som emulgeringsmiddel. Etter omrdring for å oppnå ensartet dispersjon, ble den behandlede masse formet til papirark på en Noble and Wood papirmaskin. Papirarkene som ble oppnådd ble torret og noen ark ble herdet i en time ved 105°C og undersokt på limningseffektiviteten ved å bruke blekkpenetreringsmetoden, idet antall sekunder for blekk inntas på den ovre iaktatte overflate som mål for liming. Noen ferdige papirark fikk forbli, mens andre ark ble neddykket i kloroform, torret og derpå undersokt på liming på samme måte. Prøveresultatene er satt opp i den folgende tabell. In this example, polyethyleneimine was added to a 2% paper-pulp slurry in water in an amount equal to 1% based on dry weight and stirred for 15 minutes, and then 1%, based on the weight of the pulp, of either 2-chloroethyloctadecylsulfone as a solution in p-cymen added, which were emulsified in water using hexadecyltrimethylammonium bromide (Arquad) as an emulsifier. After rearrangement to achieve uniform dispersion, the treated pulp was formed into paper sheets on a Noble and Wood paper machine. The paper sheets obtained were dried and some sheets were cured for one hour at 105°C and examined for gluing efficiency using the ink penetration method, taking the number of seconds for ink on the upper observed surface as a measure of gluing. Some finished paper sheets were allowed to remain, while other sheets were immersed in chloroform, dried and then examined for gluing in the same way. The test results are listed in the following table.
EKSEMPEL 2 EXAMPLE 2
Til en vandig oppslemning som inneholder 2 vekts$ av en bleket Gatineau-sulfitmasse raffinert til en kanadisk Standard Freeness på ca. 500t 20 ml og som har en pH på 9?0 ble tilsatt en emulsjon som er fremstilt ved å opplose 0,75 g 2,3-diklorpropyl n-octadecylsulfid eller sulfon i 5 ml xylen og blande den resulterende opplosning med 20 ml av en opplosning av 0,1$ heksadecyltrimetyl-ammoniumbromid i vann. Den behandlede vandige masse-oppslemning ble blandet i 15 minutter for å sikre ensartet distribusjon, og derpå anvendt for å fremstille papirark på en Noble and Wood papirmaskin. Noen ark ble bare torret og derpå undersokt for liming. Andre ark ble herdet i 60 minutter ved 105°C og derpå undersokt. To an aqueous slurry containing 2 wt$ of a bleached Gatineau sulphite pulp refined to a Canadian Standard Freeness of approx. 500t 20 ml and having a pH of 9?0 was added to an emulsion prepared by dissolving 0.75 g of 2,3-dichloropropyl n-octadecyl sulfide or sulfone in 5 ml of xylene and mixing the resulting solution with 20 ml of a solution of 0.1$ hexadecyltrimethylammonium bromide in water. The treated aqueous pulp slurry was mixed for 15 minutes to ensure uniform distribution and then used to produce paper sheets on a Noble and Wood paper machine. Some sheets were simply dried and then examined for gluing. Other sheets were cured for 60 minutes at 105°C and then examined.
Andre satser av den samme blekede Gatineausulfit-masseoppslemning ved pH 9 ble behandlet forst med en vandig oppslemning av et polyetylenimin, blandet som foran angitt, og med en av 2,3-diklorpropyl n-octadecylsulfid eller sulfonemulsjoner som foran. Other batches of the same bleached Gatineausulfite pulp slurry at pH 9 were treated first with an aqueous slurry of a polyethylene imine, mixed as above, and with one of 2,3-dichloropropyl n-octadecyl sulfide or sulfone emulsions as above.
De resulterende behandlede masser ble formet til ark som foran angitt, og enten torret eller herdet ved 105°C i 60 minutter som foran angitt, og derpå undersokt på limningseffektivitet ved blekkprovemetode. Noen prover ble torret med aceton, torret og derpå undersokt for å bestemme limningspermanens. Resultatene på disse prover på forskjellige papir er satt opp i folgende tabell. The resulting treated pulps were formed into sheets as above, and either dried or cured at 105°C for 60 minutes as above, and then examined for bonding efficiency by the ink test method. Some samples were dried with acetone, dried, and then examined to determine adhesive permanence. The results of these tests on different papers are set out in the following table.
Fotnote: Footnote:
1. 6000+ betyr at proven ble avsluttet ved 6000 sekunder og er indiserende for hard liming. 1. 6000+ means that the test ended at 6000 seconds and is indicative of hard bonding.
