The Uses Of Tetrasodium ethylenediaminetetraacetic acid (EDTA-4na)
As a heavy metal complexing agent, it is used to complex heavy metals in water to soften water quality. Because EDTA has a strong complexing ability, it is corrosive to some sensitive metals, such as copper/silver and so on.
EDTA 4 Na
Tetrasodium ethylenediaminetetraacetic acid
Among the salts of ethylenetetraminetetraacetic acid, the tetrasodium salt is the most important. It is an important complexing agent. Used in electroless copper plating, gold plating, lead-tin alloy plating, electrochemical polishing of steel parts and solution before silver plating of copper parts, also used in detergents, liquid soaps, shampoos, agricultural chemical sprays, color photosensitive materials Bleaching and fixing solution, water purifying agent, PH regulator, anticoagulant, etc.
In the reduction initiation system for the polymerization of styrene-butadiene rubber, tetrasodium EDTA is used as a component of the active agent, which is mainly used to complex ferrous ions and control the polymerization reaction speed.

Sodium hexametaphosphate is directly related to the glossiness of the coating. Its functions are mainly reflected in the following aspects:1.Disperse pigments and reduce particle aggregationAs an inorganic dispersant, sodium hexametaphosphate can effectively reduce the surface energy of pigment part
Polyacrylamide, referred to as PAM, is divided into anionic (HPAM), cationic (CPAM), and nonionic (NPAM). It is a linear polymer and one of the most widely used water-soluble polymer compounds. Polyacrylamide and its derivatives can be used as effective flocculants, thickeners, paper strengtheners,
In daily life and industrial production, cleaning and maintenance of metal utensils and equipment are crucial. Metal parts will inevitably carry some dirt, such as oil, solid particles and scale, during production, transportation and storage. The dirt on the metal surface can be removed by certain t
With the continuous acceleration of industrialization and the rapid growth of the economy, refractory materials, as key industrial raw materials, play a vital role in the field of high-temperature industry. In the process of widespread use and large-scale production of refractory materials, the bene
EDTA tetrasodium (EDTA-4NA) is an important chemical with a wide range of applications. It is a white crystalline powder, soluble in water, odorless and tasteless, and is a strong chelating agent. EDTA tetrasodium has the chemical formula C10H12N2Na4O8 and is soluble in water and acid, but insolu
When we usually says dispersants, you may not know what they are. When materials were not so developed, people thought that some mechanical tools that could stir were dispersants because they could muddy clean water and disperse the whole. Humans learned brewing, dyeing, smelting and other technolog
Sodium gluconate is a white crystalline powder that is easily soluble in water and has stable chemical properties. It can play a variety of roles in concrete. First, sodium gluconate is an excellent retarder that can extend the initial and final setting time of concrete, providing construction worke
Refractory material is a special material with high temperature, corrosion resistance, erosion resistance and other characteristics. It is usually used in high temperature industrial fields. In the manufacturing process of refractory materials, binder is a necessary additive. Sodium hexametaphosphat
