Description: Sodium erythorbate is a white or yellow white crystalline powder or granules, odorless, has little salt, the melting point is over 200, it is rather stable when being dry exposed to the air, but in the water solution, when there is air, metal, heat and light, the oxidation will occur. It easily dissolves in water; 16g/100ml at normal temperature, hardly dissolves in ethanol, the PH value of 2% water solution is 5.5-8.0.
Which complies with the specifications of GB8273-87, FCC for food additives
Net Weight: 25kgs/carton.
Uses: Sodium Erythorbate is mainly used in foodstuff industry, used as antioxidant, preservative and coloring agent, broadly used in meat food, fish food, beer, fruit juice, syrup crystal, fruit and vegetable tin, cake, dairy produce, confiture, sherry, pickles, and grease etc. the dosage to the meat foods is 0.5~1.0g/kg. To the frozen fish, the fish should be infused in the 0.1%-0.8% water solution before freezing. The dosage in the beverage such as syrup is 0.01%~0.03%, apple and bechamel tin: 0.15g/kg (dosage of single or together with the VC), luncheon meat, cooked meat powder, cooked front leg pork, cooked ham, the dosage is 0.5g/kg (dosage of single or together with the VC and other sodium salt, counted the VC ), for the peach, apple jam: 2g/kg,for the fruit tin, it is 0.75-1.5g/l, for the nature syrup, it is 0.08-0.11g/l, for the beer, it is 0.03g/l (FAO/WHO(1977).
Antioxidation property: the antioxidation property of the Sodium Erythorbate is great larger than the one of cenolate (Sodium VC), has no effects to identify the Vitamin C, but it will not persuade the body to absorb and use the Sodium Erythorbate. The body culls the Sodium Erythorbate and changes it into Vitamin C inside the body.
The physiological effects of the Sodium Erythorbate is only the 1/20 of the VC on anti-scurvy, but it is approximately same to the VC on drop blood pressure, diuresis, generating of hepatic glycogen, discharging of pigment, detoxifcation.

2. High slump retention performance: Normally carboxylic groups is damaged of ordinary polycarboxylate superplasticizer by the high temperature during dry spray process, this product takes the special process so protect the carboxylic groups and achieve the excellent slump retention ability.
3. Excellent solubility and fast solvability: Due to uniform particles, the specific area is larger, so the product is dissolved quickly in the water then no impurity after dissolving
DOSAGE
0.2~0.3% of the aggregate material, it is instead of liquid polycarboxylate superplasticizer after dissolving the dosage after dissolving reference to the actual solid content of dissolving liquid.
The unit technology uses extremely small air bubbles to lift suspended solids and oil to the top surface. The formed sludge layer is scraped into a sludge holding tank. The addition of coagulation and flocculation chemicals may be required to enhance the performance.
Removal efficiency is usually superior to gravity bases systems and often applied as polishing step (downstream of CPI)
The unit can be supplied with a gas-tight cover, coagulation & flocculation dosing and mixing equipment and air-saturation by special pumps or in separate pressure vessel.
Flotation consists of separating solids from the water phase by attaching the solids to fine air bubbles to decrease the densityof the particles which float instead of sinking. The rising solids are called the and are skimmed off the surface and further processed in the sludge train.Chemicals can be added to improve the separation: first for coagulation and then for flocculation.
The type of flotation used by Dissolved Air Flotation in which the suspension is saturated with air at high pressure. Bubbles are released to the water and will attach to the suspended solids.The bubbles from a system are much smaller than in other types of flotation systems and better adhere to the solids.This makes
one of the most efficient flotation options of wastewater treatment.
Copper concentrate is a refined product obtained from copper ores, boasting a higher purity level compared to its raw counterparts. It typically contains 25-30% copper, achieved through meticulous removal of impurities and unwanted elements �¹.
The production process involves several steps:
- Exploration: Identifying potential copper deposits through mapping, sampling, and surveys.
- Mining: Extracting copper ore through open-pit or underground mining methods.
- Crushing and Grinding: Breaking down the ore into smaller pieces to increase surface area.
- Froth Flotation: Separating copper minerals from waste rock using chemicals and air bubbles.
- Concentrate Thickening and Filtration: Refining the concentrate to remove excess water and impurities.
- Smelting: Heating the concentrate to eliminate unwanted elements and produce copper matte.
- Electro-Refining: Dissolving copper matte in an electrolyte solution and passing an electric current to produce pure copper cathodes.
Copper concentrate has various applications:
- Plumbing: Copper\'s non-toxic, non-permeable, and corrosion-resistant properties make it ideal for plumbing.
- Electrical and Communications Wiring: Copper\'s exceptional conductivity and ductility make it perfect for electrical wiring.
- Bronze Production: Copper is alloyed with tin to produce bronze, used in bearings, statues, and other applications.
- Heat Conduction: Copper\'s high heat conductivity makes it suitable for heat exchangers.
- Construction and Architecture: Copper is used in roofing, gutters, and decorative fixtures due to its corrosion resistance and adaptability.
- Transportation: Copper is used in vehicles, planes, trains, and ships due to its versatility and reliability.
