Below are answers to frequently asked questions at Kenno Tech: How can corrosion be prevented / how can corrosion resistance be guaranteed? Corrosion is not usually a more significant problem in cells than in traditional structures. Corrosion management methods include material selection, surface treatment, use of corrosion inhibitors inside the cell, use of potential corrosion potential, and design solutions such as arranging ventilation through the cell. Can penetrations be made in the cells? What effect do the bushings have on the strength of the cell? Penetrations are often made in the cells. Preferably, the bushings are designed for the components of the cell, but it is also possible to make the bushings for the finished cells. Large bushings are taken into account in the dimensioning of the cell and the stiffness of the cell is ensured by local reinforcement. How can cell elements be connected to each other or to other structures? There are many ways to connect. Usually, the cells have an edge profile, the design of which solves the external connections of the cell. For example, a tongue-and-groove connection can be designed for the cell, which can be locked to the adjacent cell mechanically or by welding. How can shocks and point loads be controlled from sheet metal in laser welded cells? Point load and impact control in cells may be based on one or more of the following methods: coating the cell with a spot load spreading surface plate (e.g. plywood), using high strength steels in the surface plate and / or oversizing the surface plate thickness. Is the laser welded cell element completely sealed? The laser-welded cell is practically tight. The hermetic tightness of an individual cell cannot be guaranteed without testing. How can sound transmission be controlled in cellular structures? Äänien välittymisen hallinnassa pääasialliset keinot ovat kennon sisäisten eristeiden käyttö ja/tai kennon pinnoittaminen sopivilla materiaaleilla. Mikä on kennojen elinikä perinteisiin rakenteisiin verrattuna? Oikeaan kohteeseen hyvin suunnitellun kennon elinikä on yhtä hyvä tai parempi kuin perinteisen rakenteen. Voiko kennoissa käyttää sinkittyjä materiaaleja? Sinkityn levyn laserhitsaus on hidasta ja vaikeaa ja siksi sinkittyjä materiaaleja käytetään vain erikoistapauksissa. Sama pätee myös esim. muovipinnoitettuihin levyihin. Valmiin kennon kuumasinkitys aiheuttaa merkittäviä muodonmuutoksia, joten sitä ei suositella. Pienehköjen kennojen kuumasinkitys on rajoitetusti mahdollista. Saadaanko kennoista tehokkaasti lämpöeristäviä, kun ytimet muodostavat lämpösiltoja? If the insulation of the cell cannot be sufficient with the insulation alone, a heat failure can be implemented inside the cell. How fireproof are the cells? In the event of a fire, the cell structure is good. All required fire classes can be implemented with cell structures. What opportunities does Kenno Tech have to manufacture cell structures that are not planar? 3000 mm and welding head height movement 700 mm; within these limits, we are able to manufacture a wide variety of cell structures.
