Description

LAITE VIRTAUKSEN OHJAAMISEKSI Keksinnön ala 5 Tämän keksinnön kohteena on laite virtauksen ohjaamiseksi, jollaista laitetta tarkemmin sanottuna käytetään väliaineen, kuten ilman ohjaamiseksi.FIELD OF THE INVENTION The present invention relates to a device for controlling a flow, more particularly, a device for controlling a medium, such as air.

Keksinnön tausta 10 Erilaisissa virtauksen, kuten ilmavirran ohjaukseen käytettävissä laitteissa, kuten ilmanvaihtokanavissa, poistoilmalaitteessa (kuten esim. poistoilmaventtiili tai pois-toilmasäleikkö tai muu poistoilmalaite) on ongelmana niiden pintoihin kertyvä lika, koska pintoja ei ole suojattu riittävän tehokkaasti likaa vastaan. Lian kertyminen pintoihin heikentää laitteiden käytettävyyttä ja vaatii lian puhdistamista, joka aihe-15 uttaa lisätyötä sekä kustannuksia.BACKGROUND OF THE INVENTION Various devices for controlling flow, such as airflow, such as ventilation ducts, exhaust air device (such as exhaust air valve or exhaust grille or other exhaust air device) have a problem with their surfaces because surfaces are not adequately protected against dirt. Accumulation of dirt on surfaces impairs the usability of the equipment and requires cleaning of the dirt, which requires additional work and costs.

Keksinnön tarkoituksena onkin aikaansaada laite ilman ohjaukseen, joka laite ei likaannu niin herkästi kuin tunnetut, ilmavirran ohjaukseen käytettävät laitteet. Samalla myös pyritään aikaansaamaan helposti puhdistettavissa oleva ilmavirran 20 ohjaukseen käytettävä laite.It is an object of the invention to provide a device for controlling the air which is not so dirty as the known devices for controlling the air flow. At the same time, it is also sought to provide a device for controlling the air flow 20 which is easy to clean.

§ 35 sistä lähtöaineista joko kokonaan tai osittain epäorgaaninen kiinteä verkosto kon- 00 ventionaalisia keraamipinnoitustekniikoita huomattavasti matalammissa lämpöti loissa. Kuten tekniikan nimikin viittaa, pitää se sisällään epäorgaanisen verkoston muodostumisen kolloidisen suspension (soolin) geeliytymisen kautta. Geelin kuivumisen sekä kovettumisen kautta voidaan edelleen muodostaa jatkuva kiinteä 2 verkosto, joka voi olla esimerkiksi pinnoite. Tällä tekniikalla tuotetut pinnoitteet ovat ohuita, tyypillisesti sadoista nanometreistä kymmeneen mikrometriin.Of the feedstocks, either in whole or in part, an inorganic solid network at conventional temperatures significantly lower than conventional ceramic coating techniques. As the name of the technology implies, it involves the formation of an inorganic network through the gelation of a colloidal suspension (sol). Through the drying and curing of the gel, a continuous solid network 2 may be formed, which may be for example a coating. The coatings produced by this technique are thin, typically from hundreds of nanometers to ten micrometers.

Sooli-geelikemiällä voidaan tuottaa myös epäorgaanis-orgaanisia (ts. keraami-5 polymeeri) yhdistelmämateriaaleja. Näillä nanoskaalan komposiittimateriaaleilla voidaan tuottaa läpinäkyviä ohuita pinnoitteita, joissa pystytään yhdistämään eri materiaaliryhmille tyypillisiä piirteitä molekyylimittakaavassa. Näillä pinnoitteilla voidaan materiaaliominaisuuksia säätämällä vaikuttaa muun muassa pintojen lian-hylkivyyteen, puhdistettavuuteen, itsepuhdistuvuuteen ja kulutuskestoon sekä 10 muihin suojaominaisuuksiin. Säädettäviä pintaominaisuuksia ovat muun muassa pintaenergia, topografia, pintakovuus ja pinnoitteen tiiveys. Sooli-geelipinnoitteet perustuvat usein silaanipohjaisiin ratkaisuihin, mutta pinnoitteita voidaan valmistaa myös muita metallien alkoksideja hyödyntäen.Sol-gel chemistry can also be used to produce inorganic-organic (i.e., ceramic-5 polymer) composite materials. These nanoscale composite materials can be used to produce transparent thin coatings capable of combining features typical of different groups of materials on a molecular scale. By adjusting the material properties, these coatings can influence, among other things, the dirt repellency, cleanability, self-cleaning and abrasion resistance of the surfaces as well as other protective properties. Adjustable surface properties include surface energy, topography, surface hardness and coating density. Sol-gel coatings are often based on silane-based solutions, but coatings can also be prepared using other metal alkoxides.

15 Hyötynä aiempiin orgaanisiin (esim. fluoropolymeeripohjaisiin) alhaisen pintaener-gian pinnoitteisiin voidaan sooli-geelitekniikalla tuotetuilla pinnoitteilla muun muassa saavuttaa pinnoitteen parempi adheesio pohjamateriaaliin, mikä yhdistettynä epäorgaanisten osioiden tuomaan pintakovuuden nousuun johtaa paremmin kulutusta kestäviin lopputuotteisiin. Sooli-geelitekniikan etuna on myös nestemäisen 20 pinnoitteen applikoitavuus eri märkäpinnoitusmenetelmin, mikä osaltaan edesauttaa näiden pinnoitteiden teknistaloudellista hyödynnettävyyttä.By utilizing previous organic (e.g., fluoropolymer based) low surface energy coatings, sol-gel coatings can, among other things, achieve better adhesion of the coating to the substrate, which, when combined with an increase in surface hardness provided by inorganic portions, leads to better wear resistant finishes. Sol-gel technology also has the advantage of applying the liquid 20 coatings by various wet coating methods, which contributes to the techno-economic utilization of these coatings.

Keksinnöllisen ajatuksen mukaisesti sooli-geeli pinnoitteella voidaan pinnoittaa ainakin seuraavia ilman ohjaukseen käytettäviä laitteita (tai laitteistojen osia): 25 - ilmanvaihtokanava (tulo-ja poistokanava) kuten ilmanvaihtoputki - poistoilmalaite (esim. poistoilmaventtiili tai poistoilmasäleikkö tai muu pois- o toilmalaite)According to the inventive idea, the sol-gel coating can be applied to at least the following air control devices (or parts of equipment): 25 - ventilation duct (inlet and outlet duct) such as a ventilation duct - exhaust air device (eg exhaust air valve or exhaust air grille or other exhaust air device)

§ 35 lian tarttumisen poistoilmalaitteen pintaan, jolloin tuote pysyy puhtaampana, ei 00 näytä esteettisesti rumalta, tekniset arvot säilyvät muuttumattomina, eikä vaadi niin usein puhdistamista. Poistoilmapuhaltimessa likaa hylkivä pinnoite estää lian tai rasvan kiinnittymisen poistoilmapuhaltimen juoksupyörään ja vaippaan, jolloin tekniset arvot säilyvät, tuote toimii hyvällä hyötysuhteella koko elinkaaren, pyörään 3 ei tule tasapaino-ongelmia, jotka rasittavat laakereita, eikä se vaadi niin usein puhdistusta.§ 35 adherence of dirt to the surface of the exhaust air unit, whereby the product remains cleaner, 00 does not look aesthetically unsightly, the technical values remain unchanged and does not require frequent cleaning. In the exhaust fan, a dirt-repellent coating prevents dirt or grease from adhering to the exhaust fan impeller and casing while maintaining technical values, the product operates well throughout the life cycle, wheel 3 does not have balance problems that burden the bearings and require less frequent cleaning.

Tuloilmaventtiilissä likaa hylkivä pinnoite estää huoneesta indusoidun likaisen il-5 man tarttumisen pintoihin.In the supply air valve, a dirt-repellent coating prevents room-induced dirty IL-5 from adhering to surfaces.

Pinnoite on muodostettu edellä mainittuihin laitteisiin tai niiden osiin suihkuttamalla, telaamalla tai sivelemällä.The coating is formed by spraying, rolling or brushing on the aforementioned devices or parts thereof.

10 Alan ammattimiehelle on selvää, että keksintö ei ole rajoitettu edellä esitettyihin sovellutusmuotoihin, vaan sitä voidaan vaihdella oheisten patenttivaatimusten puitteissa.It will be apparent to one skilled in the art that the invention is not limited to the embodiments set forth above, but may be varied within the scope of the appended claims.

Keksinnössä käytettävä sooli-geelipinnoite voi olla myös hybridipinnoite tai nano-15 komposiitti-hybridipinnoite.The sol-gel coating used in the invention may also be a hybrid coating or a nano-15 composite hybrid coating.
