Molten metal antioxidant biological reducing agent and preparation method thereof

Abstract

A molten metal antioxidant biological reducing agent comprises polyethylene glycol oleate, a thermophilic enzyme, a lipase, ammonium dihydrogen phosphate, ethylene diamine tetramethylene phosphonate acid and phytoncid. The molten metal antioxidant biological reducing agent is prepared by adding the components in batches slowly under a certain temperature. The molten metal antioxidant biological reducing agent has high reducing efficiency, is non-toxic, contains no carcinogenic substance, generates less flue and does not corrode machines. Particularly, the molten metal antioxidant biological reducing agent can be used for removing the redundant metal and oxide impurities released onto the surface of tin in a tin furnace to play a role of purifying and can react with a carbonized soldering flux in a high-temperature furnace to exert the reducing effect further to release metal elements. The residues from the reduction of the molten metal antioxidant biological reducing agent are water-soluble, self-degradable, pollution-free and easy to process, conform to environmental protection standards, consume less manpower for management and occupy less space for placement.

Description

technical field [0001] The invention relates to the field of molten metal technology, in particular to a molten metal anti-oxidation bioreductant and a preparation method thereof. Background technique [0002] Molten metal is often used in the manufacture of electronic products. The molten metal (or alloy) will be oxidized when it encounters air, and it will also melt and oxidize in a high-temperature furnace; the molten metal will continue to circulate in the furnace, and the oxidation speed will be accelerated. The amount of oxidized metal will increase, and the oxide will contain carbonized flux and a large amount of tin, which will accumulate and float on the tin surface to affect the flow of tin and the quality of the surface tin, so it can only be salvaged. However, the height of the tin surface will be reduced after the tin slag is salvaged, so tin strips should be added frequently. In order to make tin less prone to oxidation in air, reducing separators are required...

Problems solved by technology

In order to solve the above problems, reducing powder is often used in the prior art. Due to the raw material composition of molten metal reducing powder, this type of reducing powder has the following defects: poisonous, low reduction rate; because there is strong acid in the ingredients, most of them are strong acids Strong alkali is corrosive to the machine, and the smoke is large

In addition, there is also a type of molten metal reducing agent. This type of reducing agent is also toxic. It contains carcinogens and is irritating to the human body. The smoke has a strong smell and is corrosive to the machine. The residue is gelatinous and difficult to clean. Defects that do not meet environmental protection standards and are very expensive

In the prior art, there is also the use of a molten metal reduction machine. This solution has the following problems for visitors to the molten metal reduction machine: the quality of the molten metal itself after reduction is poor, and it consumes electricity, manpower, management and space.
