Pierwszenstwo: Zgloszenie ogloszono: 30.05.1973 Opis patentowy opublikowano: 25.02.1974 KI. 49h, 35/36 MKP B23k 35/36 Twórcywynalazku: Wlodzimierz Rdzak, Waclaw Kepka Uprawniony z patentu tymczasowego:Wytwórnia Sprzetu Komunikacyjnego „Delta—Mielec" Przedsiebiorstwo Panstwowe, Mielec (Polska) Topnik do lutowania i lutospawania Przedmiotem wynalazku jest topnik do lutowania i lutospawania, zwlaszcza stali z miedzia, stali z brazem, brazu z brazem, stali z mosiadzem oraz mosiadzu z mosiadzem. Znane sa i stosowane topniki do lutowania i lutospawania pod nazwa UNI-LUT.Wada tych topników jest to, ze lutowie nie tworzy wlasciwego zacieku lutu w procesie lutowania oraz powoduje intensywne utlenianie powierzchni czesci poddanych procesowi lutowania. Dalsza wada tego rodzaju topników jest to, ze w niedostatecznym stopniu oczyszczaja i zwilzaja powierzchnie czesci lutowanych lub lutospawanych, co ma istotny wplyw najakosc polaczenia.Celem wynalazku jest unikniecie podanych niedogodnosci, zwlaszcza wykluczenie powstawania pecherzy i por w spoinie, których usuniecie jest bardzo kosztowne a czesto wrecz niemozliwe. Dla osiagniecia tego celu zostalo wytyczone zadanie opracowania skladu topnika, który zapewnia spoinie korzystne wlasciwosci metalur¬ giczne. Do lutowania lub lutospawania tym topnikiem mozna stosowac rózne druty lub tasmy stopowe bez obawy wypalania sie wiekszych ilosci skladników stopowych.Zgodnie z wynalazkiem rozwiazanie zagadnienia, poparte wieloma doswiadczeniami, rózni sie od znanych srodków lutowniczych tego rodzaju tym, ze jest mieszanina zawierajaca wagowo 25-35 czesci boraksu, 25-35 czesci kwasu borowego, 15-25 czesci fluorku potasu, 7-12 czesci fluorku wapnia, 4-8 czesci weglanu sodu, 3-8 czesci chlorku sodu.Stwierdzono, ze korzystne wyniki uzyskuje sie stosujac mieszanine w stanie pylistym zawierajaca wagowo: 30 czesci boraksu, 30 czesci kwasu borowego, 20 czesci fluoboranu potasu, 10 czesci fluorku wapnia, 5 czesci weglanu sodu, 5 czesci chlorku sodu.Najkorzystniejszym sposobem dozowania topnika przy pracach lutowniczych jest urabianie go na paste w sta¬ nie plynnym stosujac wagowo na 100 czesci mieszaniny 50 czesci kwasu fosforowego lub ortofosforowego oraz 50 czesci wody. Paste w stanie plynnym naklada sie pedzlem lub natryskowo pistoletem na krawedzie laczo¬ nych czesci oraz na pret lub tasme lutowia.Innym sposobem dozowania jest zanurzenie podgrzanego preta w topniku w postaci pylistej. Topnik ten pozwala na otrzymanie znacznie lepszych polaczen pozbawionych przede wszystkim por i pecherzy oraz jest dogodny w uzyciu i calkowicie nieszkodliwy dla zdrowia lutownika.2 70327 PL PLPriority: Application announced: May 30, 1973 Patent description was published: February 25, 1974 KI. 49h, 35/36 MKP B23k 35/36 Creators of the invention: Wlodzimierz Rdzak, Waclaw Kepka Authorized by the provisional patent: Wytwórnia Sprzetu Komunikacyjnego "Delta-Mielec" Przedsiebiorstwo Panstwowe, Mielec (Poland) Flux for soldering and brazing The subject of the invention is a flux for soldering and brazing , especially steel with copper, steel with bronze, bronze with bronze, steel with brass and brass with brass. There are known and used fluxes for soldering and braze welding under the name UNI-LUT. The disadvantage of these fluxes is that the solder does not create the proper flow of the solder in the brazing process and causes intensive oxidation of the surfaces of parts subjected to the brazing process. A further disadvantage of this type of fluxes is that they do not sufficiently clean and moisten the surfaces of the brazed or brazed parts, which has a significant impact on the quality of the connection. The aim of the invention is to avoid the above-mentioned drawbacks, especially to exclude formation of blisters and pores in the joint, which are very expensive to remove and often even impossible. To achieve this goal, the task of developing a flux composition which provides the weld with favorable metallurgical properties. Various wires or alloy strips can be used for brazing or brazing with this flux without fear of burning out larger amounts of the alloy components. According to the invention, the solution to the problem, supported by many experiences, differs from known soldering agents of this type in that it is a mixture containing 25-35 by weight parts of borax, 25-35 parts of boric acid, 15-25 parts of potassium fluoride, 7-12 parts of calcium fluoride, 4-8 parts of sodium carbonate, 3-8 parts of sodium chloride. It has been found that favorable results are obtained by using the mixture in a dusty state containing by weight: 30 parts of borax, 30 parts of boric acid, 20 parts of potassium fluorate, 10 parts of calcium fluoride, 5 parts of sodium carbonate, 5 parts of sodium chloride. The most advantageous way to dose the flux in soldering works is to make a paste in a liquid state using by weight per 100 parts of a mixture of 50 parts of phosphoric or phosphoric acid and 50 parts of water. Liquid paste is applied with a brush or spray gun to the edges of the joined parts and to the rod or tape of solder. Another method of dosing is to immerse the heated rod in a powdery flux. This flux allows for obtaining much better connections, mainly devoid of pores and blisters, and is convenient to use and completely harmless to the health of the soldering iron. 2 70327 EN EN
