Vynález sa týká taviva pre kapilárně spájkovanie materiálov z nehrdzavejúcich ocelí, nelegovaných ocelí, médi a jej zliatin a ich,kombinaci! spájkami, obsahu júcimi striebro.The present invention relates to flux for capillary brazing of stainless steel, non-alloy steel, media and its alloys, and combinations thereof. solders containing silver.
Na spájkovanie súčastí z nehrdzavejúcich ocelí, nelegovaných ocelí, médi a jej zliatin sa používá celý rad spájok na báze me3-zinok, me3-cín, raeS-titan-zinok, ale hlavně na báze meSstriebro. Patria sem všetky typy striebornýbh spájok s obsahom striebra 15 až 72 % hmotností,A variety of solders based on me3-zinc, me3-tin, raeS-titanium-zinc, but mainly meSstriebro are used for soldering stainless steel, non-alloy steel, media and its alloys. This includes all types of silver solders with a silver content of 15 to 72% by weight,
Pri spájkovaní sa kladie ddraz na nekorozívnosť spoja, a tým i taviva. Vačšina spájkovaných súčastí pracuje v rozličných agresívnych prostrediach. Na tieto spájkované spoje sa doteraz používalo viacero typov tavív. Niektoré tavivá mali malú čistiacu aktivitu, 3al’šie obsahovali chloridy a fluoridy, ktoré spósobovali koróziu spájkovanej súčasti, Ďal’šie tavivá na báze bóru a kyslých fluoridov uvďnujú značné množstvo dymov, čo představuje váčšie množstvo toxických látok, hlavně fluorovodíka a týia sa zhorušujú pracovně podmienky pracovníkov.During soldering, the emphasis is on the corrosion of the joint and thus the flux. Most soldered parts work in a variety of aggressive environments. So far, several types of flux have been used for these solder joints. Some fluxes had low cleaning activity, others contained chlorides and fluorides that caused corrosion of the brazed component. conditions of workers.

Tavivo podlá vynálezu je možné použit na spájkovanie všetkých uvedených materiálov, spájkami na báze striebra. Tavivo máThe flux according to the invention can be used for brazing all of said materials with silver-based solders. Flux has
227 108 podstatné nižšiu dymnatosť, to je menšiu normou povolenú koncentráciu toxických plynov. Vyznačuje sa výbornou kapilaritou u všetkýoh materiálov, výborná aktivačnú schopnost', má dobré tixotropnó a adhézne vlastnosti. Zníženou toxicitou plynov zlepšuje pracovně podmienky. V porovnaní s doteraz známými tavivami neobsahuje deficitné suroviny. Pre zvýšenie tixotropných vlastností taviva podía vynálezu přidáváme 0,1 až 2 % hmot, glycerínu alebo monoetylenglykolu. Na zvýšenie adhéznych vlastností sa do taviva dává 0,3 až 3 % hmot. podvojného kremičitanu sodnodraselného alebo kyslého kremičitanu sodného alebo draselného,227 108 significantly lower smokiness, that is to say, the less toxic concentration of toxic gases permitted. It is characterized by excellent capillarity in all materials, excellent activating ability, good thixotropic and adhesive properties. It improves working conditions by reducing the toxicity of gases. Compared to the known fluxes, it does not contain any deficit raw materials. To increase the thixotropic properties of the flux according to the invention, 0.1 to 2% by weight of glycerol or monoethylene glycol are added. 0.3 to 3 wt.% Is added to the flux to increase the adhesion properties. double potassium sodium or potassium silicate, or sodium or potassium silicate,
