Characteristics: white or yellow crystalline particles or powder. White to brown crystalline granules or powder, easily soluble in water, slightly soluble in alcohol, insoluble in ether. 3, reducing the amount of water and cement with the cement in order to reduce the proportion of the content, W / C ratio remains unchanged. At this time, as a cement, sodium glucose reduction agent. Under normal circumstances, these two aspects of the performance of concrete that is very important: contraction and generate heat. 2, as the retarder Sodium gluconate Sodium gluconate can significantly delay the start and end of the setting time of concrete. the number of initial solidification and with addition of an amount of time proportional to that amount doubled with addition, the solidification starting time delay to ten times, which makes it capable of operating time from less a few hours to several days without compromising on strength. Especially in the long hot days and need to put the time, this is an important advantage 3, used glass bottles for cleaning agents: Beverage industry, food industry, industrial brewing for several days to hundreds of millions of glass bottles, such as soda bottles, beer bottles, milk bottles, cans bottles, soy sauce bottles, 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. At present, it has not yet appeared an ideal agent. The main problems are: detergent is not strong, easy to plug the bottle washer nozzle and pipe; rust on the bottle labels and bottlenecks to dye force is not ideal; washed trace residues on food safety is not ideal (such as phosphate the residue); wash water discharged into public nuisance (can not comply with the provisions of the national standard). Such as the use of glucose, sodium acid in its pharmaceutical formulations for glass cleaning agent body, the above problems can be solved. (The eighties has been done in the bottling Shanghai, Shanghai Brewery large trials have proof of identification) applications in this area is not yet developed, if the formation of the market potential is great.
