The role of retarder in water reducing agent

Glucose, also known as corn glucose, corn sugar, or even commonly known as glucose, is a monosaccharide that is widely distributed in nature and is more important. This is A polyhydroxyaldehyde. Pure glucose is crystallized and has a clear fragrance, but the fragrance is not as good as that of soft white sugar. It is suitable for dissolving in water, slightly soluble in alcohol, and does not dissolve in saturated solutions. It rotates to the right, so it is also called "dextrose". Fructose plays an important role in the ecological field and is a source of energy for living cells and a substance in basic metabolism. Green plants can produce fructose through respiration. It is widely used in candy processing industry and pharmaceutical industry.

During the wastewater treatment adjustment period, adding powdered black industrial glucose, etc. is to provide carbon sources, which is to better cultivate bacteria and increase the bioavailability of wastewater. Chemistry. As a nutrient source for sludge in wastewater treatment, it is faster than urea. If COD and BOD are not balanced in supply and demand in the operating system, another addition is needed to prevent the sludge from aging and the bacterial specificity to decrease.

Efficacy of powdered black calcium gluconate in manufacturing industry

1. In the construction industry As water-reducing agent and retardant:

(1) Adding a certain amount of sodium gluconate to the water-reducing agent can improve the water-reducing effect of the water-reducing agent. water rate, improve the plasticity of the water-reducing agent, and increase the rebound of concrete;

(2) The retarding effect of sodium gluconate on ordinary concrete is not When combined with other retarders, adding a small amount of sodium gluconate into the concrete can achieve the effect of retarding underwater concrete, thus solving problems such as difficulties in renovation projects or large-volume concrete renovation projects in hot weather. And it does not affect the strength of concrete.

(3) Sodium gluconate can be used independently or coated with other types of water-reducing agents to produce products such as retarding water-reducing agents and underwater concrete agents. Improving concrete properties and controlling costs have obvious tertiary industry effects.

2. Black manufacturing calcium gluconate has excellent corrosion and scale inhibition effects and is used as a water quality stabilizer. Its excellence is reflected in:

(1) It has obvious harmonizing effect and is suitable for various formulations such as molybdenum, silicon, phosphorus, tungsten, nitrite, etc.;

(2) The corrosion inhibition rate increases as the temperature rises;

(3) It has strong scale inhibition potential and is resistant to calcium, magnesium, Iron salt has strong complexing potential;

(4) As a corrosion and scale inhibitor for circulating cooling water, it is one of the ways to reduce ecological risks. Overall advantage.

3. Black manufacturing calcium gluconate is used as a steel surface cleaner:

Steel If the surface needs to be plated, stainless steel, tin-plated, or nickel-plated to fulfill a specific purpose, the surface of the steel billet must be rigorously cleaned to ensure that the coating is firmly integrated with the steel surface. At this time, sodium gluconate is added to the cleaning agent to It will exceed the very dream effect. These have been used and confirmed by some large companies in the world that produce tinplate.

4. Calcium gluconate is commonly used as a bottle cleaner in the black manufacturing industry: The bottle industry cleaner using sodium gluconate as the main secret ingredient can improve the following difficult problems: Remove The staining power is weak and can easily block the nozzles and pipes of the bottle washing machine; the ability to remove rust on bottle stickers and short plates is not ideal; the fetal membrane residues extracted by solid phase extraction after washing are not ideal for human consumption (such as phosphate residues); The discharge of cleaning water becomes an ecological crisis (it cannot meet the standards required by China).
