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 boiler, engine cooling water system treatment chemicals. Because it has the following specific advantages: ⑴ obvious coordination effect. Suitable for molybdenum, silicon, phosphorus, tungsten, nitrite formula, lack of coordination Effect, inhibition effect of greatly increased. ⑵ efficiency increases with increasing temperature. General corrosion inhibition efficiency increased with increasing temperature decrease, or even completely useless. But sodium gluconate on the contrary, inhibition rate within a certain range with increasing temperature increase, for example, carbon steel and other materials of the test, the temperature rose from *7 ℃ F on to **0 ℃ F, which buffer the average rate increased by 5% the above. So sodium gluconate this strange characteristic of high temperature systems or from low to high variable temperature system is ideal to use as a corrosion inhibitor. ⑶ scale capability: calcium, magnesium, iron has a strong complexing ability, so the scale are strong, especially for Fe3 + has excellent chelation, even in the full range of PH inside the role.
