Levymainen tuote - Skivlik produkt TSma keksintd koskee levymaista tuotetta, jossa on olennai-5 sesti tasomainen osa ja joka on valmistettu lignoselluloo-sapitoisesta materiaalista. KeksintO koskee erityisesti marka- tai kuivamenetelmaiia (MDF) valmistettua kuitulevya seka kuivamenetelmaiia valmistettua lastulevya. Kyseessa olevaa tuotetta voidaan erityisesti kayttaa parketin alus-10 levyna, pakkaustarkoituksiin tai mytts lattioiden suojauk-seen.The invention relates to a plate-like product having a substantially planar part and made of a lignocellulosic material. The invention relates in particular to fibreboard made of branded or dry process (MDF) and particle board made of dry process. In particular, the product in question can be used as a parquet board-10 board, for packaging purposes or for the protection of mytts floors.

On ennestaan tunnettua kayttaa kuitulevya parketin aluslevy-na. Tailainen levy on valmistettu huokoisesta kuitulevysta 15 toispuolisesti kuumapuristamalla ja taman levyn molemmat pinnat ovat sileat, toinen kova ja toinen huokoinen. Tailai-sen parketin aluslevyn epakohtana on, etta se ei tasaa alustan epatasaisuutta, etta se on suhteellisen paksu, etta se ei mahdollista tuuletusta alustan ja mainitun levyn 20 vaiilia ja etta se vaatii kaksi erillista valmistusvaihetta, minka seurauksena se on suhteellisen kallis. On myOskin tunnettua kayttaa aaltopahvia parketin alusmateriaalina, mutta sen epakohtana on, etta se ei kesta kosteutta ja etta se usein litistyy jo parketin asennusvaiheessa, jolloin 25 sen askeiaanieristysominaisuudet ovat hyvin huonot.It is previously known to use fibreboard as a parquet underlay. The spiky board is made of a porous fiberboard 15 by one-sided hot pressing, and both surfaces of this board are smooth, one hard and the other porous. The disadvantage of such a parquet base plate is that it does not compensate for the unevenness of the base, that it is relatively thick, that it does not allow ventilation of the base and said board 20 and that it requires two separate manufacturing steps, as a result of which it is relatively expensive. It is also known to use corrugated board as a base material for parquet, but its disadvantage is that it does not withstand moisture and that it often flattens already during the installation phase of the parquet, resulting in very poor ascetic insulation properties.

Kuitulevyista on myds tunnettua tehda ns. embossattuja levyja dekoratiivisiin tarkoituksiin esimerkiksi seindpanee-leiksi ym. Naihin levyihin on tehty matala kohokuviointi, 30 jonka tarkoituksena on vain saada aikaan haluttu koristeel-linen vaikutelma, esimerkiksi puujaijitelma.Fiberboard is myds known to make the so-called. embossed panels for decorative purposes such as seindpanee, etc. These panels are low embossed for the sole purpose of providing the desired decorative impression, for example a wooden arrangement.

Pakkaustarkoituksiin kaytetaan nykyisin hyvin yleisesti aaltopahvia, jonka kayttoa kuitenkin rajoittaa sen huono 35 kosteudenkestavyys ja huono lujuus.Corrugated board is now very commonly used for packaging purposes, but its use is limited by its poor moisture resistance and poor strength.

KeksinnOn tarkoituksena on aikaansaada levymainen tuote.The object of the invention is to provide a plate-like product.

2 90515 erityisesti kuitulevy, jolla vaitetaan edelia kosketeltuja, ennestaan tunnettujen ratkaisujen epakohtia.2,90515, in particular a fibreboard, by which the drawbacks of the previously known, previously known solutions are disputed.

KeksinnOn tarkoituksena on ennen kaikkea aikaansaada parke-5 tin alustana kaytettava levymainen tuote, joka tasaa pienia alustan epatasaisuuksia, joka muodostaa tuuletusrakoja alustan ja mainitun levymaisen tuotteen vaiilia, jolla on hyvåt askeiaanta ja lampoa eristavat ominaisuudet, joka joustaa ja joka kestaa kosteutta.The object of the invention is, above all, to provide a plate-like product for use as a base of a parquet, which compensates for small irregularities in the base, which forms ventilation gaps between the base and said plate-like product, has good stepping and heat-insulating properties, is flexible and moisture-resistant.

1010

KeksinnOn tarkoituksena on myOskin aikaansaada pakkaustar-koituksiin kaytettava levymainen tuote, joka voi korvata esimerkiksi aaltopahvin raskaammissa pakkauksissa, joka tarjoaa hyv3n suojan kolhuja vastaan ja joka omaa hyvan 15 kosteudenkestavyyden.It is also an object of the invention to provide a sheet-like product for packaging purposes which can replace, for example, corrugated cardboard in heavier packages, which offers good protection against bumps and which has good moisture resistance.

Nama tavoitteet on voitu toteuttaa esilia olevan keksinnOn mukaisella levymaiselia tuotteella, jonka paaasialliset tunnusmerkit ilmenevat oheisista patenttivaatimuksista.These objects can be achieved by a plate-like product according to the present invention, the main features of which appear from the appended claims.

2020

Esilia oleva keksintO perustuu siihen oivallukseen, etta levymaisen tuotteen tasomaisen osan ainakin toiseen pintaan muodostetaan pinnan tasosta ulkonevia maaramuotoisia ja -kokoisia osia, jotka ovat samaa materiaalia kuin tasomainen 25 osa ja joiden kohdalla tiheys on olennaisesti pienempi kuin sita ymparOivan tasomaisen osan tiheys.The present invention is based on the realization that at least one surface of the planar portion of the plate-like product is formed with surface-shaped and protruding portions of the same surface as the planar portion and having a density substantially lower than that of the surrounding planar portion.

KeksinnOn mukainen levymainen tuote on edullisesti kuitulevy, mutta se voi myOskin olla lastulevy. Kuitulevy voi 30 laadultaan olla kova tai puolikova. Markamenetelmaiia val- mistetun kuitulevyn tasomaisen osan paksuus on tyypillisesti vaiilia noin 2-12 mm. Kuivamenetelmaiia valmistetun levyn (MDF) tasomaisen osan paksuus on edullisesti noin 2-30 mm, mutta se voi olla jopa 60 mm.The sheet-like product according to the invention is preferably a fibreboard, but it can also be a particle board. The fiberboard may be hard or semi-hard in quality. The thickness of the planar portion of the fibreboard made by the markka method is typically about 2-12 mm. The thickness of the planar portion of the dry process board (MDF) is preferably about 2 to 30 mm, but may be up to 60 mm.

Mainittujen ulkonevien osien kohdalla tiheys on edullisesti ainakin 30 % pienempi kuin ymparOivan tasomaisen osan tiheys ja ulkonevien osien korkeus on yleensa ainakin 30 %, edul- 35 3 90515 lisesti 50-100 % tasomaisen osan paksuudesta. Ulkonevien osien huiput ovat edullisesti keskenåSn samalla tasolla. Mainitut ulkonevat osat voivat muodoiltaan esimerkiksi olla pyiJreita, lieriOmaisia, aaltomaisia, juovamaisia, suorakai-5 teen muotoisia tai tahden muotoisia.For said protrusions, the density is preferably at least 30% lower than the density of the surrounding planar portion and the height of the protruding portions is generally at least 30%, preferably 50-100% of the thickness of the planar portion. The peaks of the protruding parts are preferably at the same level. Said protruding parts may, for example, be circular, cylindrical, wavy, striped, rectangular or synchronous.

Keksinnttn mukainen levymainen tuote voidaan valmistaa siten, etta kuivamenetelmSn sirottelukoneella (valmistettaessa kuitu- tai lastulevyja) tai markamenetelman kokoojakoneella 10 (valmistettaessa kuitulevyja) muodostetut puristamattomat, tiheydeltaan tasaiset aihiot/massa-arkit kuumapuristetaan. Puristus voidaan suorittaa tasopuristimessa, jossa on val-mistettavan levyn toista tai molempia pintoja vastaan eri-tyinen muottilevy, jonka avulla puristettavaan levyyn muo-15 dostetaan mainitut maaramuotoiset ja -kokoiset ulkonevat osat. Muottilevyna voidaan kayttaa metallilevya, jonka puristettavaa levya vastaan tulevaan pintaan on tehty halu-tun muotoisia ja kokoisia syvennyksia ja/tai reikia, joiden tarkoituksena on saada puristuksessa aikaan levy, jonka 20 paksuus edelia mainittujen syvennysten ja/tai reikien koh- dalla on oleellisesti ymparistoa suurempi seka tiheys oleel-lisesti alhaisempi.The sheet-like product according to the invention can be produced by hot-pressing uncompressed, uniform-density preforms / pulp sheets formed by a dry-method sprinkler (for making fibrous or particle boards) or a mark-method collector (for making fibreboards). The pressing can be performed in a planar press having a special mold plate against one or both surfaces of the plate to be manufactured, by means of which said ground-shaped and sized protrusions are formed on the plate to be pressed. As the mold plate, a metal plate can be used, the surface of which is pressed against the plate to be pressed into recesses of the desired shape and size and / or holes, the purpose of which is to provide a plate with a thickness substantially greater than the environment at said recesses and / or holes. and the density is substantially lower.

Muottilevyyn tehtyjen syvennysten muodolla ja syvyydelia 25 yhdessa puristettavan levyn paksuuden kanssa voidaan vaikut-taa syntyviin jousto- ja vaimennusominaisuuksiin. Esimerkiksi, kun syvennys tehdaan riittavan syvaksi sen laajuuteen nahden tai paksuhko muottilevy rei'itetaan, tulee kuitule-vysta puristettaessa edelia mainitun syvennyksen tai reian 30 kohdalla hyvin huokoinen, ja uloimmat kuidut ovat vain osittain kiinnittyneet levyyn ja muodostavat siten varsin pehmean pinnan, mika joissakin eristys/pakkauskohteissa on edullista. Kun muotin syvennys tehdaan matalaksi, sileaksi ja loivareunaiseksi, saadaan taysin silea, esimerkiksi 35 nystyrapintainen levy, joka voi toimia esimerkiksi pakkauk-sissa suojana kolhuja vastaan, kun tasomainen kova pinta ottaa vastaan ulkoa tulevat iskut ja nystyrOiden tai juovien muodostama pehmeMmpi pinta vaimentaa iskut ja samalla muo- 4 90515 dostaa paksuutensa suuruisen suojaetåisyyden. Lisåksi omi-naisuuksiin voidaan luonnollisesti vaikuttaa sillå, kuinka suuri osa levyn pinta-alasta jåtetåån kovaksi/huokoiseksi.The shape of the recesses made in the mold plate and the depth 25 together with the thickness of the plate to be pressed can influence the resulting elastic and damping properties. For example, when the recess is made deep enough to its extent or a thicker mold plate is perforated, the fiber will become very porous when pressed on said recess or hole 30, and the outermost fibers will only partially adhere to the plate and thus form a fairly soft surface. / packaging items is preferred. When the mold recess is made low, smooth and bevelled, a completely smooth plate is obtained, e.g. shape 4 90515 gives a protective distance equal to its thickness. In addition, the properties can, of course, be influenced by how much of the surface area of the plate is left hard / porous.

5 Keksinnon mukainen levymåinen tuote on erityisen sopiva parketin aluslevyksi esimerkiksi mårkåmenetelmån kovalevynå tehtynå, jolloin sen paksuus voi olla tasomaiselta osaltaan esimerkiksi noin 2,5 mm ja kohoumien kohdalta esimerkiksi noin 5 mm. Kohoumat voivat esimerkiksi olla nystyroitå, 10 jotka voivat olla esimerkiksi 1 cm halkaisijaltaan ja niiden våli esimerkiksi 2 cm. Parketin alustana kåytettåesså kohoumat sijoitetaan alaspåin, jolloin ne joustavina tasaavat jonkin verran lattian pinnan epåtasaisuuksia, toimivat askelåånen eristeenå, låmmdn eristeenå (ilmatila) sekå 15 muodostavat parketin alle tuuletusraon. Kun levy lisåksi valmistetaan siten, ettå kohoumat levyå puristettaessa tulevat ylospåin, muodostaa mårkåmenetelmån kovalevyn taka-pinnan viirakuvio, kun kåytetåån sopivan harvaa viiraa, parketille sopivan åånettomån alustan.The sheet-like product according to the invention is particularly suitable as a parquet underlay, for example in the form of a wet-method hardboard, in which case its thickness may be, for example, about 2.5 mm in its planar part and, for example, about 5 mm in the case of protrusions. For example, the protrusions may be bumps, which may be, for example, 1 cm in diameter and spaced, for example, 2 cm in diameter. When used as a base for parquet, the protrusions are placed downwards, whereby they flexibly compensate for some irregularities in the floor surface, act as step sound insulation, heat insulation (air space) and form a ventilation gap under the parquet. In addition, when the board is made so that the protrusions come up when the board is pressed, the wire pattern of the back surface of the wet hardboard, when a suitably sparse wire is used, forms a soundless board suitable for parquet.

Keksinnon mukainen levymåinen tuote voidaan myoskin kiinnit-tåå tehtaalla valmiin parketin rakenneosaksi.The sheet-like product according to the invention can also be attached at the factory as a structural part of the finished parquet.

Edellå esitettyå paksumpana (tasomainen osa esim., 6-8 mm) • 25 levyå voidaan kåyttåå myds parkettia ohuempien/pehmeåmpien materiaalien alustana.Thicker than above (planar part e.g. 6-8 mm) • 25 boards can be used as a substrate for thinner / softer materials than myds parquet.

j Pakkaustarkoituksiin kohoumat voivat olla muotoillut esimer- . kiksi juoviksi levyn yhdelle tai molemmille puolille sekå 30 myos erisuuntaisiksi juoviksi, jotka helpottavat pakkauksis- sa levyjen taittamista juovia myoten.j For packaging purposes, the protrusions may be shaped e.g. strips on one or both sides of the plate, as well as strips in different directions, which make it easier to fold the sheets in the packages, thus streaking the strips.

Keksinnon mukaiset levymåiset tuotteet voidaan puristuksen yhteydesså tai sen jålkeen pinnoittaa paperilla, esimerkiksi 35 krepatulla paperilla, joka muotoutuu repeåmåttå erilaisiin muotoihin ja såilyy levymåistå tuotetta taitettaessakin låhes ehjånå. Levymåinen tuote voidaan my6skin pinnoittaa muovilla tai maalata. Keksinnon mukaisen levymåisen tuotteen I: 5 90515 valmistuksen yhteydessa voidaan sen pintaan paperin tai muovin lisaksi tai tilalle laittaa esimerkiksi lasikuitu-verkko tuotteen vahvistamiseksi.The sheet-like products according to the invention can be coated on or after pressing with paper, for example creped paper, which is formed without tearing into various shapes and remains almost intact even when the sheet-like product is folded. The sheet product can also be coated with plastic or painted. In connection with the production of the sheet-like product I: 5 90515 according to the invention, a glass fiber mesh can be placed on its surface in addition to or instead of paper or plastic, for example to reinforce the product.
