1. according to different conditions of raw water, you can do a small test before use to obtain the best quantity.
2. press for production: solid: clear water = 1/5 or so, mix and dissolve first, then add water to dilute to a solution with a content of 2-3%.
Industrial glucose solid products are pure white, white powder, and easily soluble in water.
2. The hydrolysis speed is fast and the hydration is weak. The formed alum flowers are dense and settle fast.
3. It is less affected by the change of water temperature and can meet the requirement of shearing force during the flow process.
4. It can effectively remove the aluminum ions in the source water and the residual free aluminum ions in the water after aluminum salt coagulation.
5. the dosage is small, the treatment effect is good, and the cost is saved by 10-20% compared with other coagulants.
industrial glucose has obvious effect on purification of drinking water and various industrial water. Domestic drinking water, industrial water, domestic water, domestic sewage and industrial sewage treatment, etc.
1. The role of industrial glucose in sewage: Why do you need to process glucose in sewage treatment? During the commissioning of sewage treatment, glucose in the processing industry is to provide a carbon source. This is to better cultivate bacteria and improve the biodegradability of sewage. Effectively improve the affinity of sludge, faster than the effect of urea. If the COD and BOD in the running system are not enough to supply the growth and reproduction of bacteria, they need to be added separately to prevent sludge aging and biological activity reduction.
2. Industrial grade glucose leather industry uses treated leather, such as sole leather, leather case leather, etc., which can increase its softness and reduce the agent for chrome tanning.
3. Industrial glucose is used as a cleaning agent for the surface of steel: if the surface of steel needs to be plated with bowl, chrome, tin and nickel for special purposes, such as making tinplate, galvanized sheet, chrome plating on the surface (electrical degree), etc., the surface of the billet needs to be strictly cleaned to make the coating firmly combined with the surface of steel. at this time, sodium gluconate will be added to the cleaning agent to achieve a very ideal effect.
4. Industrial glucose can be used as a cement admixture: after adding a certain amount of gluconic acid to the cement, it can increase the plasticity and strength of the concrete, and has a blocking effect, that is, delaying the initial and final solidification period of the concrete, such as adding 0.15% gluconic acid, It can extend the initial setting time of concrete by more than 10 times, that is, extend the plastic time of concrete from a few hours to a few days without affecting its fastness.
5. Industrial glucose can be used in many industrial fields such as electroplating and film manufacturing.
6. As a special cleaning agent for glass bottles: The professional cleaning agent for glass bottles with sodium gluconate as the main formula can improve the following common problems: the detergency is not strong, and it is easy to block the nozzles and pipelines of the bottle washing machine; The stain removal ability of bottle sticking and bottleneck rust is not ideal; The safety of trace residues after washing is not ideal (such as phosphate residues); Washing water is discharged as a public hazard;
Industrial glucose (bacterial industrial glucose) is also called whole sugar powder. White lumpy solid, sweet. Solid ≥ 80%,DE ≥ 95, products are widely used in sewage treatment, medicine, chemical industry, food, microbial fermentation and other industries.
1. Used in medicine to regulate the acid-base balance in the human body to restore the normal function of nerves. For the same purpose, used in food additives;
2. Used as a water quality stabilizer, its excellence is shown in:
⑴ It has obvious coordination effect and is suitable for various formulas such as molybdenum, silicon, phosphorus, tungsten, nitrite, etc. Due to the coordination effect, the corrosion inhibition effect is greatly improved;
⑵ Contrary to general corrosion inhibitors, the corrosion inhibition rate increases with increasing temperature;
(3) Scale inhibition ability technical requirements have strong complexation ability for calcium, magnesium, and iron salts, especially for Fe3 + has excellent chelation effect;
(4) As a circulating cooling water corrosion and scale inhibitor, it is unmatched by other corrosion and scale inhibitors currently used, and can achieve the effect of eliminating public hazards;
3. Used in the food industry, because it can effectively prevent the occurrence of low sodium syndrome, it can be used as a food additive. Sodium gluconate and potassium gluconate have excellent taste threshold. Sodium gluconate has no irritation and bitter taste. The salt taste is close to salt. The threshold is much higher than other organic acid salts. It is 5 times that of salt (inorganic salt), 2.6 times that of sodium malate, and 16.3 times that of sodium lactate. Sodium gluconate and potassium gluconate are used in food processing to adjust pH and improve food taste. Instead of salt processing into healthy low-salt or salt-free (no sodium chloride) food, it plays a great role in improving human health and enriching people's lives.
4. During the commissioning of sewage treatment, glucose in the processing industry is to provide a carbon source, which is to better cultivate bacteria and improve the biodegradability of sewage. If the COD and BOD in the running system are not enough to supply the growth and reproduction of bacteria, they need to be added separately to prevent sludge aging and biological activity reduction.
5. It can be used directly in the food and pharmaceutical industries, as a reducing agent in the printing and dyeing leather industry, and glucose is commonly used as a reducing agent in the mirror industry and the silver plating process of hot water bottles. In industry, a large amount of glucose is used as raw material to synthesize vitamin C (ascorbic acid)
