Description
Przedmiotem wynalazku jest topnik w postaci plynnej oraz sposób jego wytwarzania do twardego lutowania palnikami gazowymi. Topnik dozowany jest do srefy lu¬ towania za pomoca gazu palnego, zasilajacego palnik gazowy.The subject of the invention is a liquid flux and a method of producing it for brazing gas burners. The flux is dosed to the sphere of the barrel burner feeding with fuel gas gas.
Ujemna ceche stosowanych dotychczas topników do twardego lutowania stanowi charakterystyczna szklista powloka zuzla potopnikowego, trwale przylegajacego do lutowiny i jej poboczy. Zuzel potopnikowy z reguly nie rozpuszcza sie w wodzie i jest bardzo trudny do usuniecia "tak na drodze mechanicznej jak i chemicznej, a w wiekszosci przypadków musi byc usuwany ze wzgledu na zadana antykorozyjnosc i estetyke wyrobu, nakladanie powlok galwanicznych, lakierniczych itp. W konsekwencji wyste¬ puje koniecznosc stosowania niezwykle pracochlonnego Tecznego odbijania lub szlifowania zuzla, przy czym usu¬ niecie go z trudno dostepnych miejsc jest czesto w ogóle niemozliwe.The negative characteristics of the fluxes used so far do brazing is a characteristic glassy the coating of the post-flux tube, permanently adhering to solder and its edges. As a rule, Zuzel Potopnikowy does not dissolves in water and is very difficult to remove "both mechanically and chemically, and mostly cases must be deleted because of the requested anticorrosion and product aesthetics, application of coatings electroplating, varnishing etc. As a consequence, there were there is a necessity to use an extremely labor-intensive one Effectively reflect or grind the scrap, and remove it It is often removed from hard-to-reach places at all impossible.
Celem wynalazku jest opracowanie topnika, który nie pozostawialby zuzla na polutowanych polaczeniach i elimi¬ nowalby tym samym trudnosci z jego usuwaniem.The object of the invention is to provide a flux that does not it would leave badges on soldered connections and elimi it would have no problem with removing it.
Cel ten osiagnieto opierajac sklad chemiczny topnika na alkoholowym roztworze boranu trójmetylowego z dodat¬ kami stabilizatora oraz aktywizatora, których wprowadzenie do topnika wymaga odpowiedniej technologii laczenia surowców.This goal was achieved by basing the chemical composition of the flux on an alcoholic solution of trimethyl borate with the addition of kami stabilizer and activator, which introduction to the flux requires an appropriate joining technology raw materials.
Topnik zawiera wagowo: boran trójmetylowy 30 do 70%, •alkohol metylowy 25 do 64%, glikol etylenowy 5 do 8%, -wode do 0,90% oraz fluorek kwasny z grupy potasowców 4o0,07%.The flux contains by weight: trimethyl borate 30 to 70%, • methyl alcohol 25 to 64%, ethylene glycol 5 to 8%, - water up to 0.90% and acid fluoride from the group of potash 4o0.07%.
Przykladowy sklad topnika w przeliczeniu na surowce wyjsciowe moze byc nastepujacy: boran trójmetylowy — 620 ml alkohol metylowy — 310 ml glikol etylenowy — 62 ml woda — 8 ml fluorek kwasny z grupy potasowców — 0,6 g Zaleznie od potrzeb mozna uzyskac szeroka zmiane wlasnosci lutowniczych topnika, a w szczególnosci jego aktywnosc poprzez dobór odpowiedniego fluorku kwasnego z grupy potasowców oraz zmiane zawartosci boranu trój¬ metylowego.An example of the composition of the flux in terms of raw materials the output may be as follows: trimethyl borate - 620 ml methyl alcohol - 310 ml ethylene glycol - 62 ml water - 8 ml acid fluoride from the group Potashites - 0.6 g Depending on your needs, you can get a wide change the soldering properties of the flux, especially its activity by selecting the appropriate acid fluoride from the group of potassium and changes in the content of tris borate methyl.
Topnik otrzymuje sie mieszajac dokladnie rozdrobniony i rozpuszczony w wodzie fluorek kwasny z alkoholem metylowym i nastepnie dodajac boran trójmetylowy oraz glikol etylenowy. Topnik ma postac plynna i wyróznia sie okreslona lotnoscia w temperaturach otoczenia w wyniku czego jego dozowanie w strefe lutowania odbywa sie bez bezposredniego udzialu lutowacza.The flux is obtained by mixing finely ground and acid fluoride dissolved in water with alcohol and then by adding trimethyl borate and ethylene glycol. The flux is in a liquid and distinctive form become determined aerobic at ambient temperatures as a result what its dosing in the soldering zone is done without direct involvement of the solder.
W procesie lutowania, nastepuje rozklad topnika na zwia¬ zki aktywne oczyszczajace laczone metale i spoiwo nie two¬ rzac przy tym zuzlowych pozostalosci. Uzyskane polaczenia lutowane cechuje wysoka jakosc oraz metaliczna czystosc hitowin i przyleglych powierzchni elementów, bedacych podczas lutowania pod dzialaniem plomienia gazowego zawierajacego topnik.In the brazing process, the flux is decomposed into a solid active detoxifying combined metals and non-forming binder throwing away the deadly remains. Connections obtained solder is characterized by high quality and metallic purity hitowin and adjacent surfaces of the elements being when soldering under the action of a gas flame containing flux.
W rezultacie zlacza lutowane lotnym topnikiem spelniaja 102 499102 499 .3 4 warunki techniczne nakladania pokryc lakierowanych lub H20 do 0,90% i fluorek kwasny z grupy potasowców da galwanicznych. 0,07%.As a result, the joints soldered with volatile flux do not work properly 102 499 102 499 .3 4 technical conditions for applying varnished coatings or H20 up to 0.90% and acid fluoride from the group of potashites galvanic. 0.07%.
