Prosessihihnaprocess belt
Keksinnön kohteena on prosessihihna erityisesti rainan vedenpoistoa tai rainan siirtoa varten, joka prosessi-5 hihna käsittää kantavan perusrakenteen ja sen päälle sovi tetun, rainan koskettavan pinnan muodostavan kerroksen.The invention relates to a process belt, in particular for dewatering or transferring a web, which process belt 5 comprises a load-bearing basic structure and a layer forming a contacting surface of the web arranged thereon.
Tällaiset prosessihihnat ovat nykyään hyvin tunnettuja paperiteollisuuden yhteydessä. Prosessihihnoja käytetään esimerkiksi tavanomaisina puristinhuopina poistet-10 taessa vettä rainasta puristamalla.Such process belts are now well known in the paper industry. Process belts are used, for example, as conventional press felts for removing water from a web by pressing.
Prosessihihnoja on valmistettu hyvin monenlaisina toteutuksina. Yksistään puristinhuopia on markkinoilla erittäin monia tyyppejä ja niiden variaatioita.Process belts have been manufactured in a wide variety of implementations. There are many types of press blankets on the market and their variations.
Aiemmin käytettyjen huopien epäkohtana on ollut se, 15 että niiden vedenpoistokyky ei ole ollut paras mahdollinen.The disadvantage of previously used blankets has been 15 that their dewatering capacity has not been optimal.
Lisäksi huonona puolena on ollut pinnan liian suuri karkeus, jolloin raina jää sileydeltään huonoksi puristuksen jälkeen. Em. epäkohdat johtuvat mm. siitä, että huopien kontaktipinta-V alat eli ts. pinnat, joilla huopa koskettaa rainaan, ovat ·: 20 olleet liian pienet. Nykyisin käytössä olevien huopien kontaktipinta-alat ovat olleet alle 10 %. Lisäksi tunnettujen huopien ja ennenkaikkea niiden pintojen huokoskoot ovat ol-leet suhteellisen suuria. Koko huopien huokoskoot tunnetuis-- sa huovissa ovat rajoissa 50 - 200 pm. Keksimääräiset huo- 25 koskoot tunnetuissa huovissa ovat puolestaan noin 100 - 150 pm.In addition, the disadvantage has been the excessive roughness of the surface, which leaves the web having poor smoothness after compression. Em. the disadvantages are due to e.g. that the contact surface areas V of the felts, i.e. the surfaces on which the felt contacts the web, have been too small. The contact areas of the felts currently in use have been less than 10%. In addition, the pore sizes of the known felts and in particular of their surfaces have been relatively large. The pore sizes of the entire felts in the known felts are in the range of 50 to 200. The average pore sizes in known felts are in turn about 100 to 150.
Keksinnön tarkoituksena on saada aikaan prosessi-hihna, jonka avulla aiemmin tunnettujen ratkaisujen epäkohdat pystytään eliminoimaan. Tähän on päästy keksinnön 30 mukaisen prosessihihnan avulla, joka on tunnettu siitä, että rainaan koskettavan pinnan kontaktipinta-ala (FOGRA-KAM -arvo % puristuspaineella 2,5 MPa) on yli 10% ja että rainaan koskettavan pinnan muodostavan kerroksen keskimääräinen huokoskoko on olennaisesti alueella 80-0 pm.The object of the invention is to provide a process belt by means of which the disadvantages of the previously known solutions can be eliminated. This is achieved by a process belt according to the invention 30, characterized in that the contact area of the web-contacting surface (FOGRA-KAM value at% compression pressure 2.5 MPa) is more than 10% and that the average pore size of the web-contacting surface layer is substantially in the range 80-0 pm.

Koska keksinnön mukaisella prosessihihnalla on mm. suuri kosketuspinta-ala niin tavanomaisena puristinhuopana käytettynä keksinnön mukainen prosessihihna antaa korkean kuiva-aineen. Sekä tavanomaisena puristinhuopana että 5 yksinomaisena siirtohuopana käytettynä keksinnön mukainen prosessihihna antaa paperille myös hyvän sileyden. Suuren kontaktipinta-alansa ansiosta keksinnön mukainen prosessi-hihn toimii hyvin siirtohuopana, koska raina kiinnittyy hyvin huopaan. Rainan tarttuvuutta huopaan voidaan säädellä 10 edullisella tavalla kulloisenkin käyttötilanteen mukaan.Since the process belt according to the invention has e.g. the large contact area so used as a conventional press felt, the process belt according to the invention gives a high dry matter. Used both as a conventional press felt and as an exclusive transfer felt, the process belt according to the invention also gives the paper good smoothness. Due to its large contact area, the process belt according to the invention works well as a transfer felt, because the web adheres well to the felt. The adhesion of the web to the felt can be adjusted in an advantageous manner according to the particular situation of use.
Prosessihihnan pinnan pienen huokoskoon ansiosta ei tapahdu jälleenkostumista, vaikka raina saattaa olla pitkäaikai-sessakin kontaktissa huovan kanssa silloin kun huopaa käytetään puristimessa yksinomaisesti rainan siirtotarkoi-15 tuksiin.Due to the small pore size of the process belt surface, rewetting does not occur, although the web may be in prolonged contact with the felt when the felt is used in the press exclusively for web transfer purposes.
Keksintöä ryhdytään seuraavassa selvittämään tarkemmin oheisessa piirustuksessa esitetyn keksinnön erään edullisen suoritusmuodon avulla, jolloin piirustuksen kuvio esittää keksinnön mukaista prosessihihnaa periatte-20 eilisenä poikkileikkauskuvantona.The invention will now be explained in more detail by means of a preferred embodiment of the invention shown in the accompanying drawing, in which the drawing of the drawing shows the process belt according to the invention in principle in cross-section.
Kuvion esimerkissä on esitetty eräs prossesihihnan rakenneratkaisu silloin, kun prosessihihnaa käytetään tavanomaisena puristinhuopana eli huopana, joka osallistuu vedenpoistoon puristimella ottamalla vettä vastaan rainasta. 25 Rainasta tapahtuvan vedenpoiston periaate ja toteutukset ovat alan ammattimiehelle sinänsä tunnettua tekniikkaa, joten ko. seikkoja ei tässä yhteydessä selvitetä tarkemmin.The example of the figure shows a structural solution of a process belt when the process belt is used as a conventional press felt, i.e. a felt which participates in dewatering with a press by receiving water from the web. 25 The principle and implementations of dewatering from a web are a technique known per se to a person skilled in the art, so that the the issues are not clarified in this context.
Kuvion esimerkissä on viitenumeron 1 avulla merkitty puristushuovan perusrakenne, ts. peruskudos, joka muo-30 dostaa huovan kantavan rakenteen. Rainaan koskettavan pin nan muodostava kerros on merkitty kuvioon viitenumeron 2 avulla. Rainaan koskettava pinta on puolestaan merkitty numerolla 3. Kerroksen 2 alapuolella on kuvion esimerkissä toinen kerros 4. Kerros 2 on muodostettu karkeudeltaan hie- 35 nosta hahtuvasta, ts. alle 6 dtex:ä olevasta hahtuvasta ja kerros 4 puolestaan karkeudeltaan olennaisesti n. 15 dtex:ä.In the example of the figure, reference numeral 1 denotes the basic structure of the press felt, i.e. the base fabric, which forms the support structure of the felt. The layer forming the surface in contact with the web is indicated in the figure by reference numeral 2. The surface in contact with the web is in turn marked with the number 3. Below layer 2 there is a second layer 4 in the example of the figure. Layer 2 is formed of fluffy with a fine roughness, i.e. less than 6 dtex, and layer 4 is substantially fluffy of about 15 dtex: s.
3 793713 79371
Kuvion esimerkissä on viitenumeron 5 avulla lisäksi merkitty tavanomainen nurjan puolen hahtuvakerros.In the illustrated example, by means of reference numeral 5 in addition to conventional labeled reverse side batt fiber layer.
Keksinnön mukaisesti rainaan koskettavan pinnan 3 kontaktipinta-ala on yli 10 %. Rainaan koskettavan pinnan 5 3 muodostavan kerroksen 2 keskimääräinen huokoskoko on puolestaan olennaisesti alueella 80-0 ||m. Kuvion esimerkissä on lisäksi rainaan koskettavan pinnan 3 muodostavan kerroksen paksuus suuruudeltaan noin 0,5 mm.According to the invention, the contact area of the surface 3 in contact with the web is more than 10%. The average pore size of the layer 2 forming the web-contacting surface 5 3, in turn, is substantially in the range of 80-0 μm. In the example of the figure, the thickness of the layer forming the surface 3 in contact with the web is further about 0.5 mm.
Koska huovan pinnan hahtuva on karkeudeltaan n.Since the fluffy surface of the felt has a roughness of approx.
10 3 dtex:ä niin raakahuovalle on saatu jo mahdollisimman pieni huokoskoko ja mahdollisimman suuri kontaktipinta. Kontaktipintaa on lisäksi kasvutettu ja huokoskokoa laskettu hahtuvamateriaaliin lisätyn lisäaineen avulla. Kerroksen 4 huokoskokoa voidaan myös pienentää lisäaineen avulla.10 3 dtex so the raw felt has already had the smallest possible pore size and the largest possible contact area. In addition, the contact surface has been increased and the pore size has been reduced by means of an additive added to the fluff material. The pore size of layer 4 can also be reduced by means of an additive.
15 Kuviona 1 esimerkissä on siis lähdetty tavanomai sella neulausmenetelmällä valmistetusta raakahuovasta. Kosketuspintaa ja huokoisuuttaa voidaan säätää jo raaka-huopavaiheessa käyttämällä erilaisia hahtuvahienouksia ja erilaisia hahtuvien kerrostuksia sekä erilaisia kudostyyp-20 pejä perusrakenteessa. Kerroksen 2 paksuutta säätelemällä voidaan myös säädellä valmiin huovan ominaisuuksia. Huovan pinnan muodostava kerros 2 voj näin ollen runsaimmassa tapauksessa ulottua jopa huovan läpi. Tällainen sovellutus-muoto on edullinen varsinkin silloin kun huopaa käytetään 25 vain rainan siirtohuopana.Thus, in Figure 1, the example is based on a raw felt made by a conventional needling method. The contact surface and porosity can be adjusted already in the raw felt stage by using different fluff fines and different fluff layers as well as different tissue types in the basic structure. By adjusting the thickness of the layer 2, the properties of the finished felt can also be regulated. The layer 2 forming the surface of the felt thus voj thus extends even through the felt. Such an embodiment is advantageous especially when the felt is used only as a web transfer felt.
Huovan ominaisuuksia voidaan säädellä lisäksi edelleen erilaisten lisäaineiden avulla. Lisäaineilla tarkoitetaan tässä yhteydessä kaikkia aineita, jotka on tuotu huopaan tavanomaisen huovan valmistuksen aikana tai sen jälkeen 30 huovan kontaktipinnan lisäämiseksi ja huokoskoon pienentä miseksi. Tällaisia aineita ovat esimerkiksi valmistuksen aikana hahtuvaan lisätyt kuidut, joiden sulamispiste on alhaisempi kuin varsinaisen hahtuvan kuitujen sulamispiste, jolloin lisätyt kuidut sulaavat huovan viimeistelyvaiheessa. 35 Termi lisäaine käsittää myös kumit,polyuretaanit, muut muovi- materiaalit jne., joilla pystytään lisäämään huovan 4 79371 kontaktipintaa ja pienentämään huokoskokoa. Em. termi lisäaine käsittää edelleen myös erilaiset kemikaliot, joiden avulla kontaktipintaa voidaan kasvattaa ja huokoskokoa pienentää.In addition, the properties of the felt can be further regulated by means of various additives. Additives in this context refer to all substances introduced into the felt during or after the manufacture of a conventional felt in order to increase the contact surface of the felt and to reduce the pore size. Such materials include, for example, fibers added to the fluff during manufacture that have a lower melting point than the fibers of the actual fluff fibers, whereby the added fibers melt in the felt finishing step. The term additive also includes rubbers, polyurethanes, other plastic materials, etc., which are capable of increasing the contact surface of a felt 4 79371 and reducing the pore size. Em. the term additive further encompasses various chemicals that can be used to increase the contact area and reduce the pore size.
5 Rainaan koskettavan pinnan muodostavaa kerrosta 2 ei myöskään välttämättä tarvitse muodostaa hahtmaakerroksesta ja lisäaineesta, vaan kerros on mahdollista muodostaa perusrakenteen 1 päälle sovitetusta lisäainekerroksesta, joka voi olla esim. muovimateriaalia tai jotain muuta edel-10 lä mainittua lisäainemateriaalia.The layer 2 forming the surface in contact with the web also does not necessarily have to be formed of a fluff layer and an additive, but the layer can be formed of an additive layer arranged on the base structure 1, which may be e.g. a plastic material or some other aforementioned additive material.
Edellä esitettyjä suoritusesimerkkejä ei ole mitenkään tarkoitettu rajoittamaan keksintöä, vaan keksintöä voidaan muunnella patenttivaatimusten puitteissa monin eri tavoin. Näin ollen on selvää, että esimerkiksi keski-15 määräistä huokoskokoa voidaan muunnella vapaasti käyttöti lanteen mukaan. Keskimääräinen huokoskoko voi tavanomaisena puristinhuopana olla esimerkiksi vähintäin 80 - 60 μια, mutta vaativammissa tapauksissa em. arvo voi olla 60 - 20 μπι. S iirtohuopatarkoituksissa keskimääräinen huokoskoko 20 voi olla esim. vähintäin 60 - 40 pjn, mutta kohdevaatimuksi- sta riippuen huokoskoko voi olla jopa 40-0 Jim. Mikäli koko huovan huokoskoko on pienennetty, on sen huokoskoko silloin keskimäärin alle 100 pjn. Tavanomaisena puristin-huopana koko huovan keskimääräinen huokoskoko on 100 -25 40 jim ja siirtohuopana 60-0 pm. Tekstissä mainittu kontaktipinta-ala on mitattu FOGRA-kontaktisileysmittarilla (FOGRA-KAM-arvo %) puristuspaineella 2,5 MPa. Huokoskoon arvot on puolestaan saatu elohopeaporosimetrillä.The above embodiments are in no way intended to limit the invention, but the invention can be modified in many different ways within the scope of the claims. Thus, it is clear that, for example, the average pore size of 15 can be freely varied according to the application. The average pore size can be, for example, at least 80 to 60 μια as a conventional press felt, but in more demanding cases the above value can be 60 to 20 μπι. For transfer felt purposes, the average pore size 20 may be, for example, at least 60 to 40 microns, but depending on the target requirements, the pore size may be as high as 40-0 microns. If the pore size of the entire felt is reduced, then its pore size is on average less than 100. As a conventional press felt, the average pore size of the entire felt is 100 -25 40 Jim and as a transfer felt 60-0 pm. The contact area mentioned in the text is measured with a FOGRA contact smoother (FOGRA-KAM value%) at a compression pressure of 2.5 MPa. Pore size values, in turn, have been obtained with a mercury porosimeter.
Keksintöä ei ole myöskään rajoitettu sen suhteen 30 millä menetelmällä lisäaine on huopaan tuotu. Lisäaine voidaan tuoda huopaan tuomalla se huovan hahtuvan mukana, nostamalla telalla tai suihkuttamalla se nestemäisessä muodossa, vaahdottamalla, laminoimalla jne. Keksinnön mukaisen prosessihihnan kontaktipintaa voidaan myös lisätä 35 mekaanisten menetelmien avulla täysin vapaasti. Pintaa 5 79371 voidaan lisätä esim. kalanteroimalla, hiomalla jne. Kuten edellä jo on todetta keksintöä ei ole rajattu tavanomaista kudosta ja neulaustekriiikkaa hyväksikäyttävään ratkaisuun, vaan prosessihihna voi olla minkälainen hihna tahansa.The invention is also not limited to the method by which the additive is introduced into the felt. The additive can be introduced into the felt by bringing it with the felt fluff, lifting it with a roller or spraying it in liquid form, foaming, laminating, etc. The contact surface of the process belt according to the invention can also be added completely freely by mechanical methods. Surface 5 79371 can be added e.g. by calendering, grinding, etc. As already stated above, the invention is not limited to a solution utilizing conventional fabric and needling techniques, but the process belt can be any type of belt.
5 Kuvien mukaista ratkaisua voidaan luonnollisesti myös muunnella niin että kerros 4 jätetään pois tai vaihtoehtoisesti kerroksen 4 tilalla on useita kerroksia. Mikäli rainaan koskettavan pinnan muodostava kerros muodostetaan suoraan perusrakenteen päälle niin on selvää että kerros 10 voidaan muodostaa millä tahansa menetelmällä ja mistä tahansa em. lisäaineesta tai niiden seoksista.Of course, the solution according to the figures can also be modified so that the layer 4 is omitted or, alternatively, the layer 4 is replaced by several layers. If the layer forming the surface in contact with the web is formed directly on the base structure, it is clear that the layer 10 can be formed by any method and from any of the above-mentioned additives or mixtures thereof.
