Sodium gluconate for concrete

Specification

Sodium Gluconate is the sodium salt of gluconic acid, produced by fermentation of glucose. Sodium Gluconate is a white to tan, granular to fine, crystalline powder, very soluble in water.Sodium Gluconate is non corrosive, non toxic and resistant to oxidation and reduction, even at high temperatures. It is readily biodegradable (98% after 2 days).

Application

C6H11NaO7 effectively inhibits scale formation by binding calcium and magnesium ions in hard water, thus preventing deposits in boilers, cooling towers, and heat exchangers. It works well with phosphonates and polymers in antiscalant formulations. Additionally, it forms protective films on metal surfaces, especially steel and copper, reducing corrosion rates in closed-loop cooling systems at pH ranges of 7.0-9.5. In cleaning applications,Sodium gluconate removes iron oxide deposits in membrane cleaning formulations and degrades calcium carbonate scales without damaging equipment. It's commonly used in RO/UF membrane cleaning at concentrations of 0.5-2%. In industrial water systems, typical dosage ranges from 5-50 ppm depending on water hardness. As a biodegradable alternative to phosphates and EDTA, it is compatible with most water treatment chemicals.

According to the different types of fermentation enzymes used, fermentation methods can be divided into two stages: one is to use enzymes from Aspergillus Niger, the other is to use acids, and the latter is to use glucose dehydrogenation to form lactones, which are then decomposed.

Sodium gluconate retarding admixture functions by disrupting the normal hydration process of cement, which delays the setting and hardening times of concrete.

Enhanced Performance: Provides better performance in high-temperature environments by slowing down the setting process, which can otherwise accelerate.

The packaging design of chemical products in powder form is unique. Each bag of products is sealed with woven bags, and the outer layer is woven bag packaging to ensure that the net weight of the product is within the precise range of 25 kg or 40 kg, which is easy to carry and transport. Liquid products are packaged in 200kg plastic barrels, or 1000kg and 1150kg IBC barrels. During transportation, please pay attention to waterproofing and scratch prevention to protect the integrity of the barreled products and avoid damage to the normal use of the products. For storage, this concrete additive needs to be stored in a special warehouse to ensure a ventilated and dry environment. Its shelf life is two years. Even if it exceeds this period, it can still be used as long as it is tested and confirmed to be of qualified quality. However, if it encounters agglomeration caused by moisture, it needs to be dried and crushed before use to ensure that its performance is not affected.
