Durable surface treatment of metals for the chemical industry and waste economy
Thermoplastic metal coatings are not only used in exterior but also because of their properties they are an excellent solution even in aggressive environments. An example is the surface treatment of the wastewater treatment plant.
Požiadavky na povrchovú úpravu oceľovej konštrukcie kalolisu:
- chemická odolnosť
- vysoká mechanická odolnosť
- vynikajúca priľnavosť povrchovej vrstvy
- dlhá životnosť
- hrubá vrstva povlaku 1000 μm
 | |
Konštrukcia kalolisu mala veľké rozmery a pomerne komplikovaný tvar. Najdlhší diel meral 5,5 m a najťažší vážil 750 kg.
 | |
Tradičné povrchové úpravy nevedeli garantovať dlhú životnosť a kvalitu výsledného povlaku v danom prostredí. Investor sa preto rozhodol pre termoplastické povrchové úpravy. Realizátorom povrchovej úpravy bola spoločnosť IPC s.r.o.. Ing. Vladimír Martinko, majiteľ spoločnosti: „Za pomoci mobilného zariadenia Gladiátor sme aplikovali termoplastický povlak na kovovú konštrukciu. Jedná sa o modernú, funkčnú povrchovú úpravu poskytujúcu vynikajúcu, dlhodobú, antikoróznu ochranu kovov v exteriéri a v agresívnom prostredí so životnosťou počítajúcou na desiatky rokov.“
 | |
Mobilné zariadenie Gladiátor umožňuje povrchovú úpravu i veľkých nadrozmerných oceľových konštrukcií. Pracuje na princípe plameňometu, ktorým sa kov nahrieva a následne aplikuje termoplastický prášok. Ten sa vplyvom tepla taví a vytvára trvácny povrch. Hrúbka vrstvy je viac ako 500 μm, pevne drží na kove, nepraská, neolupuje sa. Termoplastická povrchová vrstva je dolná voči UV žiareniu, soli, chemickým látkam, hlavne kyselinám, čistiacim prostriedkom, odoláva mrazu a nepriazni počasia.
