Sodium naphthalene sulfonate formaldehyde years

Sodium naphthalene sulfonate formaldehyde years there has been bleeding,
segregation and slump loss with time and other shortcomings. We find that, by (1) to extend the condensation time (2) adding acid modified S two ways to reduce the slump loss at the same time, can significantly reduce bleeding; and analysis found that adding 11% of modified S carboxyl content of the finished product, yield increased after acid, sulfonated increased by 10%. Naphthalene superplasticizer have raw cheap, simple synthesis process and low cost advantages. However, the disadvantage of sodium naphthalene sulfonate formaldehyde is also well known, such as bleeding, segregation, slump when big loss, poor adaptability to different cement. Years of study at home and abroad
to improve its shortcomings [1-3] a lot, but most of the time focused on improving the slump loss. Focus describes the condition of the characteristics of superplasticizer, research and development. Some issues to be raised further study and research trends sodium naphthalene sulfonate formaldehyde. Ultra-fine mineral admixture is inorganic non-metallic materials.

Superplasticizer is currently the most widely used research and a concrete admixtures, concrete admixtures has become other than cement, sand, stone fifth part of [1]. One is to improve the concrete mixing water reducing admixtures rheological properties of water reducer in concrete slump is basically the same and does not affect sodium naphthalene sulfonate formaldehyde the workability conditions, with less water, raising the temperature effect of admixtures. Synthesized by molecular design various functional groups containing carboxylic acid copolymer (CoPoCa-300) admixtures, and naphthalene sulfonic acid formaldehyde condensates get a new series of complex composite superplasticizer
CoPoCa-NSF series. Superplasticizer compound reduces the amount of sodium naphthalene sulfonate formaldehyde and produces ultra-additive effect of
the composite water reducer has a high water reduction (24% to 28%) and good slump retention, can significantly improve the strength of the concrete 40% to 50%. Currently widely used in domestic superplasticizer mainly naphthalene sulfonic acid formaldehyde condensate (referred naphthalene superplasticizer), amino acid salt series polycarboxylate polymers and superplasticizer [1].
Polycarboxylate superplasticizer series is widely recognized as a new, green high-performance water-reducing agent [2-4], the biggest advantage of this type of water-reducing agent is water reducing rate.

Used as a cleaning agent sodium gluconate

Used as a cleaning agent sodium gluconate: Beverage industry, food industry, brewing industry, the number of days to hundreds of millions of dollars in glass bottles, such as soda bottles, beer bottles, milk bottles, cans bottles, soy sauce, wine bottles, etc., the cleaning work is a very important thing, cleaning pharmaceutical formulations agent is a higher degree of difficulty of the technical work. Currently not yet appeared an ideal drug. The main problems are: detergent is not strong, easy to plug the washing machine nozzle and pipe; rust on bottle labels and bottlenecks to dye force is not ideal; washed trace residues on food security is not ideal (such as phosphate residues); wash water discharge into public nuisance (can not comply with the national standard). Such as sodium gluconate use in pharmaceutical formulations in their glass as the main cleaning agent, the above problems can be solved. (Eighties bottling has been done in Shanghai, Shanghai brewery large trials have identification to prove) this application is not yet developed, if a market has great potential. Water is used as a stabilizer: Because sodium gluconate has excellent corrosion and scale effect, it is widely used in water stabilizer, such as the petrochemical
business cycle cooling water system, low pressure boilers, engine cooling water systems and other treatment agents.

Because it has the following specific advantages: ⑴ obvious coordination effects. Suitable molybdenum, silicon, phosphorus, tungsten, nitrite formulations, the coordination Effect, the inhibition effect is greatly improved. ⑵ corrosion rate increases with increasing temperature. General corrosion inhibition efficiency increased with increasing temperature drop, or even completely useless. But contrary sodium gluconate, corrosion rates within a certain range to improve with increasing temperature, for example, carbon steel and other materials test, the temperature rose from 77 ℃ F on to 120 ℃ F, its average rate of 5% buffer above. Therefore, this singular feature of sodium gluconate, the higher the temperature of the system from low to high temperatures or temperature variation system, is ideal to use as a corrosion inhibitor. ⑶ scale capability: calcium, magnesium, iron complex has a strong ability to scale so strong, particularly Fe3 + chelation excellent, even in the full scope of the role of internal PH. ⑷ eliminate pollution. Using sodium gluconate as circulating cooling water corrosion inhibitor, to eliminate pollution, which is an advantage other corrosion inhibitor currently in use can not be compared. Used in medicine: Regulation of acid-base balance in the human body to restore nerve function properly, but also for the same purpose, for food additives.For medicine, you can adjust the acid-base balance in the human body
to restore nerve function normally, for the same purpose, used in food additives; Water is used as a stabilizer, and its superiority in: ⑴ obviously coordinated effects, for molybdenum, silicon, phosphorus, tungsten, nitrite, and other formulations, the coordination Effect, inhibition effect of greatly increased;
⑵ contrast with the general sodium gluconate corrosion, corrosion rate increases with increasing temperature; ⑶ scale technical ability requirements for calcium, magnesium, iron has a strong complexing ability, particularly Fe3 + has an excellent chelating;

Steel surface cleaning agent: steel surface plated bowl as needed, chrome, tin, nickel-plated to suit the special purpose, its slab surface shall be rigorously cleaned, the coating material combined with a solid steel surface, this time adding its cleaning agents sodium gluconate will achieve very good results;
Pipeline; rust on the bottle labels and bottlenecks to dye force is not ideal; washed trace residues on food security is not ideal (such as phosphate residues); wash water discharged into public nuisance; Sodium gluconate as a retarder
Sodium gluconate can significantly delay the start time and the end of the solidification of the concrete. In the amount of 0.15% or less, with the logarithm of the initial solidification increase the amount of time proportional relationship, that with increase the amount to double clotting time delay to the start times, which makes it able to work from the time few hours to a few days without compromising on strength. Especially hot days and a longer time to be placed, this is an important advantage.
