MENETELMÄ JA LAITTEISTO PÄÄLLYSTYSTERÄN TAI VASTAAVAN KULUTUSTA KESTÄVÄN PINNOITTEEN VALMISTAMISEKSIMETHOD AND EQUIPMENT FOR PREPARING A COATING BLADE OR THEIR CONSUMPTION COATING

Tämän keksinnön kohteena on menetelmä paperirainan käsittelyyn tarkoitetun 5 käsittelyterän, kuten päällystys- tai kaavinterän, kulutusta kestävän timantin kaltaisen pinnoitteen valmistamiseksi.The present invention relates to a process for producing a wear-resistant diamond-like coating for a paper-blade processing blade, such as a coating or doctor blade.

Keksintö koskee myös laitteistoa sellaisen terän kulutusta kestävän innoitteen valmistamiseksi.The invention also relates to apparatus for making such a blade a wear-resistant inspiration.

Paperin päällystyksessä paperia pinnoitetaan yleensä jollakin pastamaisella lisäaineella, jossa on esimerkiksi pigmenttiä ja sideaineita. Päällystyksellä pyritään parantamaan paperin pinnan ominaisuuksia. Päällystys tapahtuu paperikoneen päällystysyksikössä, jossa pinnoitusaine levitetään ohjapaperin pintaan ja tasoite-15 taan. Päällystäminen voi tapahtua esimerkiksi teräpäällystimessä, jossa pinnoitusaine levitetään paperin pintaan ja tasoitetaan päällystystelan sekä sen yhteyteen järjestettyjen päällystysterän avulla. Päällystysterän paperirainaa kohti oleva reuna on viistetty.In paper coating, the paper is generally coated with a paste additive such as pigment and binders. The coating aims to improve the surface properties of the paper. The coating takes place in a paper machine coating unit where the coating material is applied to the surface of the guiding paper and to the leveling compound. The coating can take place, for example, in a blade coater in which the coating material is applied to the paper surface and leveled by a coating roll and a coating blade arranged in connection therewith. The edge of the coating blade towards the paper web is bevelled.

20 Päällystysterien kulumiskestävyyden lisäämiseksi päällystysterän paperirainan puoleinen reuna pinnoitetaan kulutusta kestävällä materiaalilla, kuten keraamisella, tai kovametallisella aineella (esim. Ti02 tai WC-Co). Pinnoitetulla terällä saavutetaan pidempi kestoikä, vähemmän teränvaihtoja, vähemmän paperihylkyä, enemmän paperia samalla koneajalla ja parempi paperin laatu.In order to increase the wear resistance of the coating blades, the paper-side edge of the coating blade is coated with a wear-resistant material such as ceramic or hard metal (e.g. TiO2 or WC-Co). A coated blade achieves longer life, less blade changes, less paper waste, more paper at the same machine time, and better paper quality.

Koneen osia voidaan suojata muillakin pinnoitteilla kuin termisesti ruiskutetuilla pinnoitteilla (Themal sprayed coatings). Kulutusta kestävien osien pinnoittaminen tapahtuu usein myös ohutkalvopinnoituksena. Pinnoitus tapahtuu usein PVD ^ (Physical Vapour Deposition) reaktoreissa joissa pinnoituslämpötila on riittävänMachine parts can be protected with coatings other than Themal sprayed coatings. Coating of wear-resistant parts is also often done as a thin film coating. Coating is often carried out in PVD ^ (Physical Vapor Deposition) reactors with sufficient coating temperature

Päällystysterien pinnoitusta rajoittaa kuitenkin terien suuri koko 2000-12000 mm.However, the coating of the coating blades is limited by the large size of the blades from 2000 to 12000 mm.

S Terät ovat kuitenkin ohuita tyypillisesti 0.4 *80 mm, näin ollen taipuisia. Näin pitkiä o g 35 teriä ei saada mahtumaan pinnoituslaitteisiin, joiden tyhjökammion halkaisija on c\j usein alle 1000 mm.S However, the blades are typically 0.4 * 80 mm thin and therefore flexible. Such long o g 35 blades cannot be accommodated in coating devices which often have a vacuum chamber diameter less than 1000 mm.

2 Tämän keksinnön tarkoituksena on poistaa tunnetun tekniikan epäkohdat ja saada aikaan uudenlainen timantinkaltainen pinnoite (DLC, Diamond Like Coating), menetelmä ja laitteisto (PVD, Physical Vapour Deposition) päällystysterän tai vastaavan reunassa olevan kulutusta kestävän pinnoitteen valmistamiseksi.The object of the present invention is to eliminate the drawbacks of the prior art and to provide a new type of Diamond-like Coating (DLC), a method and an apparatus (PVD, Physical Vapor Deposition) for producing a coating blade or similar abrasion resistant coating.

Keksinnön mukainen menetelmän eräs sovellutusmuoto perustuu siihen ajatukseen, että koska päällystysterin kuluminen tapahtuu ainoastaan terän reunasta, riittää terän pinnoittaminen sen reuna alueelta 2-12 mm. Tällöin terän pinnoittaminen voi tapahtua kietomalla terä spiraalille rummun ympäri, jolloin vain pinnoi-10 tettava alue terästä näkyy.An embodiment of the method according to the invention is based on the idea that, since the wear of the coating blade occurs only at the edge of the blade, it is sufficient to coat the blade from the edge region of 2 to 12 mm. The coating of the blade can then be done by wrapping the blade on a spiral around the drum, whereby only the area to be coated is visible.

Yksityiskohtaisesti keksinnön mukaiselle menetelmälle ja laitteistolle tunnusomaiset piirteet on esitetty oheisissa patenttivaatimuksissa.Detailed features of the method and apparatus of the invention are set forth in the appended claims.

15 Saavutetut edut aiempiin teränvalmistusmenetelmiin verrattuna: Myös pitkät terät voidaan pinnoittaa DLC:llä PVD reaktoreissa. Sen lisäksi keksinnön mukainen pinnoitusjärjestely on yksinkertainen ja edullinen.15 Advantages over previous blade manufacturing processes: Long blades can also be coated with DLC in PVD reactors. In addition, the coating arrangement according to the invention is simple and inexpensive.

Seuraavassa keksintöä selostetaan yksityiskohtaisemmin esimerkin avulla viit-20 taamalla oheisiin piirustuksiin, joissa kuvio 1 esittää keksinnön mukaisella laitteistolla valmistettua päällystysterää sovitettuna päällystystelan yhteyteen, 25 kuvio 2 esittää keksinnön mukaista teräpinnoitusta.In the following, the invention will be described in more detail by way of example with reference to the accompanying drawings, in which Figure 1 shows a coating blade made with an apparatus according to the invention fitted to a coating roll, Figure 2 shows a blade coating according to the invention.

o g 35 Kuva2: Kietomalla terä 4 kartiomaisen rummun DRUM1 ympärille spiraalille voi- c\j daan pieneen pinnoitusreaktoriin (kammio) REACTOR1 laittaa taipuisaa teränau- haa jopa useita satoja metrejä. Koska päällystysterin kuluminen tapahtuu ainoastaan terän reunasta, riittää terän pinnoittaminen sen reuna-alueelta 2-12 mm. Kun 3 terän pinnoittaminen voi tapahtua kietomalla terä spiraalille rummun ympäri, vain pinnoitettava alue terästä näkyy. Kietomalla terä edellä kuvatulle kiepille voidaan ratkaista pitkän kappaleen reunan pinnoitusongelma.o g 35 Fig. 2: By wrapping the blade 4 around a conical drum DRUM1, a small coating reactor (chamber) REACTOR1 can be inserted into a flexible blade strip up to several hundreds of meters. Since the wear of the coating blade occurs only at the edge of the blade, it is sufficient to coat the blade from its edge area 2 to 12 mm. While the 3 blades can be coated by wrapping the blade on a spiral around the drum, only the area to be coated is visible. Wrapping the blade on the coils described above can solve the problem of coating the edge of a long piece.

5 Nykyisin käytetyt terät karkaistaan, pinnoitetaan keraameilla tai kovametallilla käyttöiän lisäämiseksi (esim. WC-CoCr tai Ti02). Terän kulumisen väheneminen perustuu pinnoitteen kovuuteen. Pinnoitteiden ja karkaisun kovuus vaihtelee HV 700-1500 välillä. Lisäämällä pinnoitteen kovuutta voidaan terän käyttöikää lisätä. Edellä mainittuja pinnoitteita kovempaa on timantti tai timantinkaltaiset hiilipinnoit-10 teet (DLC= Diamond Like Coating). Timantin kaltaista pinnoitetta käytetään, koska timantti on tunnetuista aiheista kovinta, Vikkersin asteikossa noin HV 10000. Käyttämällä timanttia voidaan terän kestoa lisätä merkittävästi. Lisäämällä terän kestoa voidaan terän vaihtoväliä paperikoneessa lisätä merkittävästi. Pinnoite muodostetaan esihiotun terän reunaan 1-20pm vahvuisen kalvona. Kuvassa 2 on 15 esitetty skemaattisesti pinnoitteen sijainti esihiotulla terällä.5 The blades currently used are hardened, coated with ceramic or carbide to increase the service life (eg WC-CoCr or TiO2). The reduction in blade wear is based on the hardness of the coating. The hardness of coatings and hardening ranges from HV 700-1500. By increasing the hardness of the coating the blade life can be increased. Tougher than the above coatings are diamond or diamond-like carbon coatings (DLC = Diamond Like Coating). A diamond-like coating is used because the diamond is the hardest known material on a Vikkers scale of about HV 10000. Using a diamond can significantly increase the blade life. Increasing the blade duration can significantly increase the blade change interval in the paper machine. The coating is formed on the edge of the pre-milled blade in the form of a film of 1-20 pm. Figure 2 shows schematically the location of the coating with a pre-sanded blade.

Keksinnön mukainen menetelmä paperirainan ja telapinnan käsittelyyn tarkoitettu päällystys-ja kaavinterän pinnoittamiseksi toimii seuraavasti: - terän valmistusmenetelmä on tunnettu siitä, että terä pinnoitetaan alipaineessa 20 <0.1 bar PVD menetelmällä timantin kaltaisella pinnoitteella teräsnauhaan - teräsnauha on kiedottu spiraalille pinnoituskammiossa joko vapaasti tai sylinterin ympäri. Nauhaa voi olla 3-1000 m kiepillä - pinnoitettava alue on nauhakiepin näkyvällä ulkopinnalla 2-12 mm alueella - pinnoite tehdään tarvittaessa esihiottuun reunaan, joka on leveydeltään 0.1-3 25 mm - esihiotun reunan kulma voi olla 0-60° - pinnoite on timantinkaltaista pinnoitetta (DLC).The method of coating the coating and scraper blade for treating a paper web and a roll surface according to the invention works as follows: the blade manufacturing method is characterized in that the blade is coated at 20 <0.1 bar PVD with a diamond-like coating on a steel strip; The strip can be 3-1000 m wide - the area to be coated is 2-12 mm on the visible outer surface of the strip - the coating is applied to a pre-sanded edge, which is 0.1-3 25 mm wide - the angle of the pre-sanded edge can be 0-60 ° - (DLC).
