3. Silver and zinc twist button battery silver extraction technology: the positive electrode of silver zinc battery is mainly stored in the form of silver oxide, and the silver content of different types of batteries is different, generally between 15% and 35%, and the rate is 95%-99%, which shows that the silver and zinc battery refining has a higher value and profit. With the enzymatic method ** Silver in Waste Film :

The amount of silver used in X-ray soft films accounts for 1 5 of the total amount of silver used in industry. Chemists at Osaka University in Japan have invented a biological method to break down the photosensitive emulsion in the soft film, which can ** the silver in the soft film. They attacked the soft film layer with a bacterial enzyme, releasing silver ions into the solution and precipitating.

This method is non-contaminating, and the used soft sheet polyester base can be reused. The pilot plant in Osaka plans to process 1 t of used X-ray soft films per day.

Silver brazing is a brazing method in which the base metal or brazing metal to be joined is silver.

Brazing refers to the welding method in which the brazing metal below the melting point of the weldment and the weldment are heated to the melting temperature of the brazing material at the same time, and the liquid brazing material is used to fill the gap of the solid workpiece to make the metal connection.

During brazing, the oxide film and oil stain on the contact surface of the base metal should be removed first, so as to facilitate the capillary tube to play a role after the brazing metal is melted, and increase the wettability and capillary fluidity of the brazing metal. According to the different melting points of brazing metals, brazing is divided into hard brazing and soft brazing.

According to the different base metals or brazing metals to be connected, it can be divided into aluminum brazing, stainless steel brazing, titanium alloy brazing, superalloy brazing, ceramic brazing, composite brazing, as well as silver brazing, copper brazing, etc.

Hello, 60% of the silver content of the silver solder sheet is worth between 10 yuan and 100 yuan. The melting point (lower than that of copper and iron) is firm. Soldering copper parts (copper pipes) will not melt the copper parts to be welded.

Welding saw blades do not anneal, etc. Copper electrode is a copper-zinc alloy, and the oxyalkyne flame brazed copper electrode used for metal is phosphorus-containing copper, which has been made as a silver-free electrode to replace silver electrode due to its good self-detergency and good fluidity and wettability.

Summary. Hello silver-copper-indium brazing, also known as silver-copper alloy, refers to a silver alloy with copper as the main alloying element. The copper content in silver-copper alloys varies and the color varies, from silver-white to rose-red.

The crystallization is fine, no brittleness, and the wear resistance is better than that of sterling silver. Its outstanding feature is its strong resistance to sulfides. It is used as an electrical contact material, such as AGCU5, etc.

It has good mechanical properties, wear resistance and fusion welding resistance, and is mainly used as high-voltage, high-current relay contacts and electrical contacts in light and medium-load circuits. It has good electrical conductivity, fluidity and wettability, and is widely used in the electric vacuum industry.

Silver solder is a component of the electrode that contains silver in it, and hard brazing metal means that it has a high melting point! Hope it can help you Lik Sang Machinery Han Sheng.

Silver brazing solder is an alloy system with silver as the base material, and the welding temperature is generally low.

Hard brazing and soldering is a method to distinguish the types of brazing with 450 degrees as the boundary, higher than 450 degrees for hard brazing, and higher than 900 degrees for high temperature brazing, which are related to the brazing temperature of the alloy.
