(54) Frita pre přípravu základného smaltu k nanášaniu za sucha v elektrostaticko!» poli(54) Frit for the preparation of basic enamel for dry application in the electrostatic field
Vynález sa týká frity pre přípravu základného smaltu k nanášaniu za sucha v elektrostatickom poli, vhodnej najma pre spósob nanášania základíného a krycieho smaltu s jedným vypalováním.The invention relates to a frit for the preparation of dry-base enamel in an electrostatic field, suitable in particular for a method of applying single-firing base and top enamel.
Známe frity tohto druhu podlá súčasného stavu techniky majú, popři všetkých výhodách, vyplýva;júcich z jednorázového vypalovania, svoju nevýhodu v tom, že sú náročné na povrchová predúpravu plechu, t. j. na odmasťovanie a morenie.Known frits of this kind according to the state of the art have, in addition to all the advantages resulting from disposable firing, the disadvantage that they are demanding for surface pre-treatment of the sheet, i.e. for degreasing and pickling.
Tieto nevýhody v značnej miere odstraňuje frita podlá vynálezu, ktorého podstata spočívá v tom, že frita obsahuje v hmotnostnej koncentrácii:These disadvantages are largely eliminated by the frit according to the invention, which consists in the fact that the frit contains, by weight concentration:
Výhodou frity pódia vynálezu popři tom, že ide o fritu vhodnú pre nanášanie základného smaltu v procese s jedným vypalováním, je.aj to, že je menej náročná na povrchová predúpravu plechu. Aj pri vynechaní morenia z povrchovej predúpravy si smalt zachovává velmi dobrú prídržnosť.The advantage of the frit according to the invention, while being a frit suitable for applying a base enamel in a single firing process, is that it is less demanding for surface pre-treatment of the sheet. Even if the pickling is omitted from the surface pre-treatment, the enamel retains a very good adhesion.
V dalšom je uvedený jeden z príkladov zloženia , frity, ktorej zložky sú vyjádřené v hmotnostnej koncentrácii:The following is one example of a frit composition whose components are expressed in weight concentration:
kysličník křemičitý SiO2 ..........28 % kysličník boritý B2O3 .........22 % kysličník sodný Na2O .........21% ' kysličník draselný K2O .......... 4 % kysličník hlinitý A12O3 ........ 4 % kysličník barnatý BaO ......... 4 % kysličník, vápenatý CaO .......... 5 % kysličník železitý Fe2O3 ........ 1,5% fluorid vápenatý CaF2 ......... 6\4 % kysličník fosforečný P2O5 ......... 1 % kysličník nikelnatý NiO .......... J %’ kysličník kobaltnatý CoO ......... 0,8 %, kysličník manganičitý MnO2 ........ 1,3%silicon dioxide SiO 2 ....... 28% boron oxide B 2 O 3 ......... 22% sodium oxide Na 2 O ......... 21% ' potassium oxide K 2 O .......... 4% aluminum oxide A1 2 O 3 ........ 4% barium oxide BaO ......... 4% calcium oxide CaO .......... 5% ferric oxide Fe 2 O 3 ........ 1.5% calcium fluoride CaF 2 ......... 6 \ 4% phosphorus pentoxide P 2 O 5 ......... 1% nickel oxide NiO .......... J% 'cobalt oxide CoO ......... 0,8%, manganese dioxide MnO 2 ........ 1.3%
Spftsobi aplikácie frity podlá vynálezu je nasledóviíý:The application of the frit according to the invention is as follows:
Frita s;a zomelie s vhodným hydrofobizačným prostriedkom, t. j. obafovadlom na konečnú jemnost’ mletia so zvyškom 2,3 až 8 % hmotnosti naFrit s and grind with a suitable hydrophobizing agent, i.e. a finish fineness grinding with a balance of 2.3 to 8% by weight
2.09294 site 63 gm, aleho so zvyškom 1,3 až 4,9% hmotnosti na site 78 μ á preoseje sa cez šito 250 μπι. Prášok musí mať měrný elektrický odpor minimálně ΙΟ12 Ω . m a vhodnú fluiditu. Prášok tohoto smaltu sa nastrieka v elektrostatickom poli tak, že sa vytvoří vrstva o plošnej hustotě nánosu2.09294 sieve 63 gm, but with a balance of 1.3 to 4.9% by weight on a 78 μ sieve and sieved through a 250 μπι sieve. The powder must have a specific electrical resistance of at least ΙΟ 12 Ω. has suitable fluidity. The powder of this enamel is sprayed in an electrostatic field so as to form a layer of surface density
