Jerzy Kwiecien, Emil Kolasinski Wlasciciel patentu: Instytut Mechaniki Precyzyjnej, Warszawa (Polska) Sposób aluminiowania zanurzeniowego siatek drucianych, zwlaszcza siatek do gazowych promienników podczerwieni Przedmiotem wynalazku jest sposób aluminio¬ wania metoda zanurzeniowa siatek drucianych, a zwlaszcza siatek do gazowych promienników podczerwieni, dla podniesienia ich zaroodpornosci ' Dotychczas zaroodporne siatki przeznaczone do gazowych promienników podczerwieni sa wyko¬ nywane z drutu chromowo-niklowego. Zaroodpor- nosc tych siatek nie jest dostateczna, co pociaga za soba niska ich trwalosc.Dla podniesienia zaroodpornosci siatek aluminio¬ wania zanurzeniowego przy uzyciu znanych top¬ ników w postaci mieszanin takich zwiazków, jak: NaCl, KC1, Na3AlF6 albo BaCl2, NaCl, NaF wzgle¬ dnie CaBr2, NaCl, Na3AlF6 lub tez KJ, NaCl i A1F3 oraz zestawów wyzej wymienionych z dodatkiem Na2B407 i NH4C1. Wyniki byly ujemne, gdyz nie osiagano potrzebnej zwilzalnosci, szczególnie w miej¬ scach stykania sie drutów. Równiez i dodatki skla¬ dników organicznych w postaci roztworu wodnego krochmalu kukurydzanego zawierajacego zawiesine M0O3 nie daly pozytywnych wyników.Sposób wedlug wynalazku polegajacy na zasto¬ sowaniu obok znanych mieszanin topników, soli sodowej karboksymetylocelulozy pozwala na osia¬ gniecie dobrej zwilzalnosci.Sposób wedlug wynalazku umozliwia zastapienie drutu chromowo-niklowego drutem stalowym. Co wiecej, trwalosc aluminiowanych siatek z drutu stalowego jest kilkakrotnie wieksza. Podczas gdy czas gwarancyjny dla siatek chromowo-niklowych wynosi 2000 godzin, wyniki badan prowadzonych na siatkach wykonanych sposobem wedlug wynalazku wskazuja na to, ze okres gwarancyjny mozna pod¬ niesc juz do okolo 8000 godzin. 5 Sposób wedlug wynalazku polega na oczyszcze¬ niu gotowych siatek, a mianowicie na odtluszcze¬ niu i wytrawieniu w dowolny znany sposób. Przed samym zanurzeniem do kapieli cieklego aluminium siatki umieszcza sie w roztworze wodnym topnika 10 o skladzie: 5—50 g/l, najlepiej 10 g/1 chlorku amo¬ nowego, 10—100 g/l najlepiej 30 g/l flurocyrkonia- nu potasu lub czteroboranu sodu oraz 0,5—5 g/l, najlepiej 1 g/l soli sodowej karboksymetylocelu¬ lozy. Po zanurzeniu do topnika siatki umieszcza 15 sie w kapieli z cieklego aluminium.Dla dodatkowego powiekszenia zaroodpornosci siatki po aluminiowaniu wyzarza sie w temperatu¬ rze 700—900°C w ciagu 0,5—2,5 godziny, zaleznie od srednicy drutu, w atmosferze powietrza lub 20 w atmosferze zdysocjowanego amoniaku.

Jerzy Kwiecien, Emil Kolasinski Patent owner: Instytut Mechaniki Precyzyjnej, Warsaw (Poland) Method of dip coating wire nets, especially nets for gas radiators The subject of the invention is the method of aluminizing wire nets, especially nets for gas infrared heaters, in order to increase their resistance to heat. Until now, heat-resistant nets intended for gas infrared heaters are made of chromium-nickel wire. The heat resistance of these nets is insufficient, which implies their low durability. To increase the heat resistance of hot dip aluminization nets using known fluxes in the form of mixtures of such compounds as: NaCl, KC1, Na3AlF6 or BaCl2, NaCl, NaF or CaBr2, NaCl, Na3AlF6 or also KJ, NaCl and A1F3 and the combinations mentioned above with the addition of Na2B407 and NH4Cl. The results were negative because the required wettability was not achieved, especially in the areas where the wires were joined. Also, the addition of organic ingredients in the form of an aqueous solution of corn starch containing a suspension of MoO3 did not give positive results. The method according to the invention consisting in the use of sodium carboxymethyl cellulose in addition to known flux mixtures allows to obtain a good wettability according to the invention. chrome-nickel wire with steel wire. Moreover, the durability of the aluminized steel wire mesh is several times greater. While the warranty period for chromium-nickel grids is 2,000 hours, the results of the tests carried out on the grids according to the invention show that the warranty period can be extended up to approximately 8,000 hours. The method according to the invention consists in cleaning the finished meshes, namely degreasing and etching in any known manner. Before the immersion of the liquid aluminum into the bath, the nets are placed in an aqueous solution of the flux 10 composed of: 5-50 g / l, preferably 10 g / l, ammonium chloride, 10-100 g / l, preferably 30 g / l, potassium flurocirconate or sodium tetraborate and 0.5-5 g / l, preferably 1 g / l, of sodium carboxymethyl cellulose. After immersion into the flux, the meshes are placed in a bath of liquid aluminum. air or in an atmosphere of dissociated ammonia. PL
