Description

Przedmiotem wynalazku jest sposób otulania ceramicznych wyrobów zasadowych zwlaszcza ogniotrwa¬ lych oraz zestaw urzadzen do stosowania tego sposobu.The subject of the invention is a method of coating ceramic basic products, especially refractory materials lenses and a set of devices for applying this method.

Znany dotychczas w przemysle materialów ogniotrwalych sposób otulania ceramicznych wyrobów zasadowych polega na recznym przyklejaniu otulin metalowych do ksztaltek ceramicznych przy uzyciu kleju polichloroprenowego typu butopren lub kleju epoksydowego typu epidiam.A method of covering ceramic products, known so far in the refractory industry basic consists in manually sticking metal covers to ceramic shapes using an adhesive polychloroprene type butoprene or epidiam type epoxy adhesive.

Niedogodnoscia tego sposobu jest to, ze wymaga on odtluszczania otulin stalowych po ich cieciu i gieciu wiazacego sie z odpowiednim wyposazeniem w urzadzenia j)o tego celu oraz z duzym nakladem pracy.The disadvantage of this method is that it requires degreasing of the steel covers after cutting and bending them. involving the appropriate equipment j) for this purpose and with a large amount of work.

Stosowane do odtluszczania srodki sa przewaznie latwopalne, stanowiace bezpieczenstwo pracy, a ponadto wymagaja dodatkowego zabiegu polegajacego na suszeniu odtluszczonych otulin. Uzycie kleju typu butapren ma ponadto te niedogodnosc, ze dla uzyskania dobrej spoiny nalezy przed sklejeniem odparowac rozpuszczalnik, co powoduje duze straty czasu oraz zwiekszone zapotrzebowanie na powierzchnie produkcyjna, jak równiez duze utrudnienie w zmechanizowaniu procesu oklejania.The degreasing agents used for degreasing are usually flammable, ensuring work safety and, moreover, require an additional treatment consisting in drying the degreased lagging. The use of butaprene glue has in addition, the disadvantage is that in order to obtain a good bond, the solvent must be evaporated before bonding, i.e. causes large losses of time and increased demand for production space, as well as large impediment in mechanizing the gluing process.

Zastosowanie natomiast do oklejania otulin kleju epoksydowego ma te zasadnicza wade, ze jest on klejem dwuskladnikowym i nalezy go sporzadzac bezposrednio przed uzyciem, co wymaga dodatkowego wyposazenia i nakladu pracy na sporzadzanie mieszanin z dokladnie odwazonej zywicy i utwardzacza oraz czestego czyszczenia latwopalnym rozpuszczalnikiem uzytego do klejenia sprzetu. Ponadto klej ten wykazuje pewne wlasciwosci toksyczne, a oklejanie nim wymaga stosowania obfitej wentylacji. Wspólna wada obydwu klejów w przypadku otulania wyrobów jest ich wydluzony czas wiazania, co umozliwia niedopuszczalne zmiany polozenia otuliny na ksztaltce w przypadku natychmiastowych manipulacji zaladowczych i transportowych. Wada ta stanowi równiez utrudnienie dla mechanizacji procesu klejenia i organizacji wysokowydajnych stanowisk produkcyjnych.On the other hand, the use of epoxy glue for covering lagging has the fundamental disadvantage that it is an adhesive two-component and should be prepared immediately before use, which requires additional equipment and effort to mix carefully weighed resin and hardener and frequent cleaning with a flammable solvent used for bonding equipment. In addition, this adhesive has some properties toxic, and sticking to it requires abundant ventilation. A common disadvantage of both adhesives in the case of products are covered with their extended setting time, which allows for unacceptable changes in the position of the cover on Ksztaltce for immediate loading and transport manipulations. This disadvantage is also impediment to the mechanization of the gluing process and the organization of high-performance production stations.

Celem wynalazku jest usuniecie przytoczonych wad i niedogodnosci.The aim of the invention is to eliminate the indicated drawbacks and inconveniences.

Zgodnie z wynalazkiem cel ten uzyskano w wyniku zastosowania zmechanizowanego procesu otulania przy uzyciu do klejenia kleju termotopliwego.
