Description
i DK 168349 B1in DK 168349 B1
Den foreliggende opfindelse angår en fremgangsmåde af den i krav 1's indledning angivne art.The present invention relates to a method of the kind set forth in claim 1.
Det er kendt at forsyne f.eks. beholdere med antivedhæftnings-lag, idet man først gør den almindeligvis af metal fremstil-5 lede beholders indre overflade ru ved hjælp af sandstråler, derpå påfører, f.eks. påsprøjter antivedhæftningslaget, almindeligvis på basis af polytetrafluorethylen (PTFE) og til slut brænder antivedhæftningslaget fast deri.It is known to supply e.g. containers with anti-adhesive layers, first roughening the generally surface of metal-made containers by sand blasting applied thereto, e.g. sprays the anti-adhesive layer, usually on the basis of polytetrafluoroethylene (PTFE), and finally the anti-adhesive layer burns firmly therein.
Fra GB-A-956.740 kendes en fremgangsmåde til opbygning og 10 fremstilling af en overflade, som skal anvendes til husholdningsgenstande, f.eks. kogegryder, stegepander og strygejern. Ved den kendte fremgangsmåde bliver en metallisk overflade af husholdningsgenstanden først gjort ru ved hjælp af sandstråler. Derpå bliver et lag påført af en legering, som fortrins-15 vis indeholder aluminium, kobber, kobber-nikkel eller jern, eller af glas i form af et porøst lag. På dette porøse lag med en tykkelse imellem 50 μιη. og 380 μτη bliver til sidst påført et antivedhæftningsmateriale, f.eks. PTFE. PTFE-laget bliver påført med en sådan tykkelse, at de porøse legeringslag bliver 20 fuldstændig overdækket. Antivedhæftningslaget bliver derpå hærdet under varmebehandling. Til sidst sker en mekanisk efterbehandling ved hjælp af en polerskive, med hvilken antivedhæftningslaget igen bliver afslidt mekanisk så langt, at det porøse legeringslags spidser eller øer igen kommer til syne.GB-A-956,740 discloses a method for constructing and manufacturing a surface to be used for household objects, e.g. cooking pots, frying pans and iron. In the known method, a metallic surface of the household object is first roughened by sand blasting. Then a layer is applied by an alloy which preferably contains aluminum, copper, copper nickel or iron, or of glass in the form of a porous layer. On this porous layer with a thickness between 50 μιη. and 380 μτη are eventually applied to an anti-adhesive material, e.g. PTFE. The PTFE layer is applied to such a thickness that the porous alloy layers are completely covered. The anti-adhesive layer is then cured during heat treatment. Finally, a mechanical finishing is done by means of a polishing disc, with which the anti-adhesive layer is again mechanically worn away so that the tips or islands of the porous alloy layer appear again.
25 Ved med denne kendte fremgangsmåde fremstillede husholdningsgenstande har antivedhæftningslaget ganske vist på sin side en bedre hæftning på husholdningsgenstandens overflade, end hvis antihæftningslaget var blevet anbragt umiddelbart på den sandstrålede metalliske overflade af husholdningsgenstanden ifølge 30 den tidligere kendte fremgangsmåde, men i praktisk anvendelse kan antihæftningslaget dog stadig gå af. Lagets mekaniske modstandsevne er også kun blevet forbedret uvæsentligt, fordi legeringslaget ikke har større hårdhed end husholdningsgenstandens metalliske materiale. Endelig er den afsluttende DK 168349 B1 2 mekaniske overfladebehandling af antivedhæftningsmaterialet yderst besværlig og kræver adskilt bearbejdningsplads, således at en flydende fremstilling ikke er mulig med den kendte fremgangsmåde. Men fremfor alt synes det foreslåede afsluttende 5 mekaniske fremgangsmådetrin med afpolering næppe anvendeligt i praksis, fordi en afpolering under seriefremstillingsbetingelser næppe vil kunne foretages så reproducerbart, at spidserne eller øerne af det påsprøjtede legeringslag dukker op i definerede størrelse fra antivedhæftningslaget.25 In the case of household articles made with this known method, the anti-adhesive layer, for its part, has a better adhesion to the surface of the household article than if the anti-adhesive layer had been applied directly to the sand-beamed metallic surface of the household article according to the prior art method, still get off. The mechanical resistance of the layer has also been significantly improved only because the alloy layer has no greater hardness than the metallic material of the household object. Finally, the final mechanical coating of the anti-adhesive material is extremely cumbersome and requires separate processing space so that a liquid preparation is not possible with the known method. Above all, however, the proposed final mechanical step of polishing seems hardly applicable in practice because a polishing under series fabrication conditions can hardly be made so reproducible that the tips or islands of the sprayed alloy layer appear in defined size from the anti-adhesive layer.
10 Fra GB-A-944.836 kendes en anden lignende fremgangsmåde, ved hvilken en overflade af en stegepande ligeledes først bliver sandstrålet. På den sandstrålede overflade bliver så anbragt et porøst oxidlag af nikkel og chromoxider samt aluminiumoxider ved hjælp af flammesprøjtning, og det i flere lag. Den 15 samlede tykkelse af det således dannede oxidlag andrager omtrent 170 μηα. Det således påførte oxidlag bliver, såfremt det falder for ru ud i sin overflade, glattet ved slibning ved hjælp af en oxid-slibesten. Herved skal det sikres, at det efterfølgende påførte antivedhæftnings lag dækker det samlede 20 oxidlag. Antivedhæftningslaget bliver fremstillet af et poly-fluorkulstof og påført ved hjælp af et farvesprøjteapparat i tre gennemgange med en samlet tykkelse på omtrent 76 μπι. Antivedhæftningslaget bliver til sidst tørret ved ca. 93°C, dernæst hærdet ved 385°C og til sidst endnu engang tørret ved 25 93°C i et længere tidsrum.From GB-A-944,836 another similar method is known in which a surface of a frying pan is also first sandblasted. A porous oxide layer of nickel and chromium oxides as well as aluminum oxides by flame spraying is then applied to the multi-layered surface. The total thickness of the oxide layer thus formed is approximately 170 μηα. The oxide layer thus applied, if it falls too roughly into its surface, is smoothed by grinding by means of an oxide abrasive. In this way, it must be ensured that the subsequent applied anti-adhesive layer covers the total 20 oxide layers. The anti-adhesive layer is made of a poly-fluorocarbon and applied by means of a three-pass paint sprayer with a total thickness of approximately 76 μπι. The anti-adhesive layer is eventually dried at approx. 93 ° C, then cured at 385 ° C and finally again dried at 25 93 ° C for an extended period of time.
De med denne kendte fremgangsmåde fremstillede genstande benytter dermed oxidlaget i det væsentlige som hæftemiddel imellem den metalliske pandebund og antivedhæftningslaget, hvis tykkelse er næsten halvt så stor som tykkelsen af selve oxid-30 laget. Dermed kan antivedhæftningslaget ridses næsten ligesom det er tilfældet ved en sædvanlig stegepande med et lag PTFE.Thus, the articles made by this known method utilize the oxide layer substantially as an adhesive between the metallic brow base and the anti-adhesive layer, the thickness of which is nearly half that of the oxide layer itself. Thus, the anti-adhesive layer can be scratched almost as is the case with a conventional frying pan with a layer of PTFE.
Opfindelsen har i forhold hertil til formål at videreudvikle en fremgangsmåde af den indledningsvis angivne art, således at husholdningsgenstandene vil kunne fremstilles med ekstremt DK 168349 B1 3 mekanisk stabilitet, men samtidig også med fremragende anti-vedhæftningsegenskaber.The object of this invention is to further develop a method of the kind mentioned initially, so that the household objects can be manufactured with extremely mechanical stability, but also with excellent anti-adhesive properties.
Dette formål opnås ved, at den indledningsvis angivne fremgangsmåde er ejendommelig ved det i krav 1's kendetegnende del 5 angivne.This object is achieved by the fact that the method of introduction initially is characterized by the characteristic part 5 of claim 1.
De enkelte fremgangsmådetrin forstærkes derved på fordelagtig måde. Ved en sammenvirkning mellem vedhæftningsgrundlaget og hårdstoflaget opnås for det første en optimal fastholdelse af laget på husholdningsgenstandens sædvanligvis metalliske bund.The individual process steps are thereby advantageously enhanced. Firstly, by an interaction between the adhesive base and the hard fabric layer, an optimal holding of the layer on the usually metallic base of the household article is achieved.
10 Men fremfor alt medfører samvirkningen af det findimensionere-de antivedhæftningslag på hårdstoflaget en særlig fordelagtig virkning. Ved at antivedhæftningslaget kun tyndt dækker hård-stoflagets spidser, opnås nemlig, at den dannede overflade på den ene sider er lige så hård som en keramik, men på den anden 15 side ligeså glidedygtig som en PTFE-belægning.10 Above all, however, the interaction of the fine-dimensioned anti-adhesive layer on the hard fabric layer has a particularly advantageous effect. By only covering the tips of the hard-fabric layer thinly, the anti-adhesive layer achieves that the surface formed on one side is as hard as a ceramic, but on the other hand is as slip-resistant as a PTFE coating.
Ved foretrukne udførelsesformer for fremgangsmåden ifølge opfindelsen består vedhæftningsgrundlaget af en nikkel-aluminium-legering eller en chrom-nikkel-legering. Hårdstoflaget består derimod fortrinsvis af aluminiumoxid eller en blanding 20 af aluminiumoxid og titanoxid. Til antivedhæftningslaget anvendes fortrinsvis PTFE.In preferred embodiments of the process of the invention, the basis of attachment consists of a nickel-aluminum alloy or a chromium-nickel alloy. The solid material layer, on the other hand, preferably consists of alumina or a mixture of alumina and titanium oxide. PTFE is preferably used for the anti-adhesive layer.
Som lagtykkelse indstilles for vedhæftningsgrundlaget fortrinsvis 10 μιη. til 20 μτη, mens hårdstoflaget fortrinsvis skal være 60 μπι tykt.Preferably, as a layer thickness for the adhesion base, 10 μιη is set. to 20 μτη, while the hard material layer should preferably be 60 μπι thick.
25 Som indbrændingstemperatur for antivedhæftningslaget anvendes fortrinsvis et område mellem 250°C og 350°C.Preferably a range between 250 ° C and 350 ° C is used as the burn-in temperature of the antifoam layer.
Opfindelsen egner sig især til bestemt husholdningsredskaber, især pander, gryder og bageforme, der som bekendt er forsynet med et antivedhæftningslag for at stege-, omrørings- og bage-30 materialet ikke klæber fast derpå. Sådanne husholdningsredskaber kommer under tilberedningen af madvarer, men især også DK 168349 B1 4 ved rengøring, hyppigt i berøring med hårde genstande, f.eks. skeer, gafler, børster, hæverter og tilsvarende genstande, således at på sædvanlig måde påførte antivedhæftningslag hyppigt er ridsede efter vedvarende brug eller ovenikøbet løsner 5 sig i flager. Her hjælper opfindelsen, idet der stilles et antivedhæftningslag til rådighed, der har en klart forbedret levetid også ved ikke særlig omhyggelig omgang med husholdningsbeholderen .The invention is particularly suitable for particular household utensils, especially pans, pots and baking trays which, as is well known, are provided with an anti-adhesive layer so that the roasting, stirring and baking material do not adhere thereto. Such household utensils come during the preparation of food items, but especially also when cleaning, frequently in contact with hard objects, e.g. spoons, forks, brushes, heaters, and similar items, so that in the usual manner the anti-adhesive layers applied are frequently scratched after sustained use or even loosened in flakes. Here, the invention assists, by providing an anti-adhesive layer which has a clearly improved service life even with not very careful handling of the household container.
Særlig fordelagtig kan opfindelsen imidlertid benyttes til 10 strygejerns strygestål. Som bekendt har nutidens strygejern ligeledes en antivedhæftningsbelægning på glidesålen, for at man også kan stryge særlig sarte stoffer med lille mekanisk modstand. Stryger man imidlertid beklædningsgenstande, der kan have hårde elementer, især metalknapper, lynlåse, nitter og 15 tilsvarende genstande, kan dette føre til, at antivedhæft-ningslaget på strygejernets glidesål ridses eller løsner sig i flager. Også her medfører opfindelsen på fordelagtig måde en hjælp, idet glidesålens levetid klart forbedres.However, it is particularly advantageous to use the invention for iron irons. As is well known, today's irons also have an anti-adhesive coating on the slip sole, so that especially delicate fabrics with little mechanical resistance can be ironed. However, ironing items that may have hard elements, especially metal buttons, zippers, rivets and similar items, may cause the antifoam layer on the iron sole to scratch or loosen in flakes. Here, too, the invention provides an advantageous aid, as the life of the slip sole is clearly improved.
Opfindelsen forklares nærmere neden for i beskrivelsen under 20 henvisning til tegningen. På tegningen viser fig. 1 en pande i delsnit og med et meget forstørret udsnit, fig. 2 en til fig. 1 svarende afbildning, men dog for et strygejern, og fig. 3 i endnu større forstørret snit et hårdstoflag med et 25 antivedhæftningslag til forklaring af opfindelsen.The invention is further explained in the description below with reference to the drawing. In the drawing, FIG. 1 is a partial sectional pan with a greatly enlarged section; FIG. 2 is a view of FIG. 1 is a view similar to that of an iron, and FIG. 3 shows an even larger enlarged section of a hard fabric layer with an anti-adhesive layer for explaining the invention.
I fig. 1 ses en stegepande 10, der i det væsentlige består af et metalbasislegeme 11 og et greb 12. Metalbasislaget 11 kan bestå af stål, rustfrit stål, støbt aluminium, støbejern, kobber eller tilsvarende materiale. Man kan imidlertid også 30 benytte keramiske pander.In FIG. 1 shows a frying pan 10 consisting essentially of a metal base body 11 and a handle 12. The metal base layer 11 may consist of steel, stainless steel, cast aluminum, cast iron, copper or similar material. However, ceramic pans can also be used.

Basislegemet 11 har en indre overflade 11a, som hidtil er blevet gjort ru ved mekaniske fremgangsmåder, især ved sandbestråling. I modsætning hertil er der ifølge opfindelsen forudset først at give den indre overflade 11a et vedhæftnings-5 grundlag 13 ved plasmasprøjtefremgangsmåden. Vedhæftnings-grundlaget 13 består fortrinsvis af nikke-aluminium eller chrom-nikkel, men der kan også benyttes andre vedhæftnings-grundlag indeholdende en nikkel legering, således som det er kendt fra plasmasprøj tef remgangsmådernes teknik.The base body 11 has an inner surface 11a which has hitherto been roughened by mechanical methods, especially by sand irradiation. In contrast, according to the invention, it is envisaged to first provide the inner surface 11a with an adhesive base 13 in the plasma spraying process. The adhesive base 13 preferably consists of nickel-aluminum or chromium-nickel, but other adhesive bases containing a nickel alloy may also be used, as is known from the plasma spraying technique.
10 På vedhæftningsgrundlaget 13 er der ligeledes ved plasmasprøj -tefremgangsmåden påført et hårdstoflag 14. Hårdstoflaget 14 kan f.eks. bestå af aluminiumoxid eller en blanding af alumi-niumoxid/titanoxid, men man kan også benytte andre hårdstoflag indeholdende aluminiumoxid, således som de kendes fra plasma-15 sprøjtefremgangsmådens teknik.10 On the adhesive base 13, a hard material layer 14 is also applied to the plasma spraying process. may consist of alumina or a mixture of alumina / titanium oxide, but other hard solids containing alumina may also be used, as known in the art of the plasma spraying method.
Hårdstoflaget 14 er på sin overside forsynet med et i og for sig kendt antivedhæftningslag 15, der fortrinsvis består af en plast på fluorethylenpolymerbasis, især polytetrafluorethylen (PTFE) . Antivedhæftningslaget påsprøjtes fortrinsvis på hård-20 stoflaget 14. Efter påsprøjning af antivedhæftningslaget 15 indbrændes dette, hvortil der er forudset et temperaturområde mellem 200 og 500°C, fortrinsvis 250 og 350°C, og især 300°C.The hard fabric layer 14 is provided on its upper side with an antifoam layer 15 known per se, which preferably consists of a fluorethylene polymer-based plastic, in particular polytetrafluoroethylene (PTFE). The anti-adhesive layer is preferably sprayed onto the hard fabric layer 14. After spraying of the anti-adhesive layer 15, this is burned to which a temperature range between 200 and 500 ° C, preferably 250 and 350 ° C, and especially 300 ° C is predicted.
Det forstås, at den i fig. l viste stegepande 10 kun skal tages som et eksempel på et antal beholdere, således som de 25 især finder anvendelse som køkkenredskaber.It is understood that the embodiment shown in FIG. 1, the frying pan 10 is only to be taken as an example of a number of containers, such as the 25 in particular being used as kitchen utensils.
I fig. 2 ses et strygejern 20, hvis glidesål 22 har den i udsnittet meget forstørrede gengivne struktur svarende til den i fig. l viste. Man ser, at der på et metalbasislegeme 21a først er påført et vedhæftningsgrundlag 23, på dette et hårdstoflag 30 24 og på dette igen et antivedhæftningslag 25. Antivedhæft ningslaget 25 danner giidesålen 22's underside.In FIG. 2 shows an iron 20 whose sliding sole 22 has the enlarged reproduced structure of the section similar to that of FIG. 1. It is seen that on a metal base body 21a, first, an adhesive base 23 is applied, on this a hard fabric layer 30 24 and on this again an anti-adhesive layer 25. The anti-adhesion layer 25 forms the underside of the guide sole 22.
Lagene 23-25's materialer og disses mål svarer i det væsentli-The materials and layers of the layers 23-25 substantially correspond to
