Q:What is the brazing flux
When the flux of low melting point, called soldering, such as soldering; when the flux of high melting point, called brazing, such as brazingSoldering flux is usually a mixture of rosin as the main component. It is an auxiliary material to ensure the smooth progress of welding process. Welding is the main process in electronics assembly process, flux is used in welding materials, the main role is to remove the solder and flux of materials to be welded on the surface of the oxide, the metal surface to achieve the necessary cleanliness. It again to prevent surface oxidation during welding, reduce the surface tension of welding material, improve the welding performance of flux. The quality directly affects the quality of the electronic products.
Q:I want to ask, before the flux, solder paste and red glue unopened, in the fridge, and food can be put together? Is there any harm to the human body?
Must not, and very unhappy
Q:Silver copper phosphorus brazing welding electrode and a copper tube with no flux?
The copper tube and the copper tube do not need welding flux when welding the copper tube and the brass piece
Q:How to judge the quality of a soldering flux?
Your question is very difficult...... What kind of soldering flux is good?A flux suitable for production needs is good! There are many kinds of soldering flux. According to the production process, there are mainly tin fluxes. Wave soldering flux, hand dipped flux, these three categories. Their standards are different. The pH value, corrosion to copper, the proportion of halogen content, solid content, resistance welding surface insulation resistance, solvent extraction, odor, smoke volume, solution appearance is different. Before the guy who said the proportion of the proportion of 0.80-0.82 should be measured.The specific weight of tin spray flux is 1. Can you say it's not good? There are also IC rosin based soldering fluxes, some of which can reach 0.85......To judge whether the flux is good or bad should be judged by whether it can meet the needs of production. The answer is for reference only
Q:Manual tin pot what kind of flux should be used (lead wire end immersion tin), the proportion of how much?
The flux is matched with a chemical liquid. Taking the question, I'm telling you the secret recipe
Q:Is there any environmental protection for soldering flux?
Look at what you ask for environmental protection, that's all. ROHS generally passes
Q:Solder soldering for stainless steel. What is used as soldering flux?
Teach you a few simple ingredients: hydrochloric acid, phosphoric acid, and zinc chloride. Use a certain proportion of water to dissolve. According to look at what can buy materials locally, these can meet the general requirements for welding, welding, ha ha ha, in relation to a confidentiality, more sorry, this is not to say.
Q:Is carbon dioxide gas shielded welding wire a flux cored wire?What is the explanation of solid cored wire?.
Two wire wire flux is fierce treasure is carbon dioxide wire surface is anti rust paint
Q:What component of a soldering flux conducts electricity?
It is the main component of solder paste
Q:Flux problem
Flux is a mixture containing a variety of volatile substances, leaving only one night without halogen halogen substances.
