为什么使用葡萄糖酸钠作为腐蚀阻垢剂?首先,葡萄糖酸钠有很多功能和功能,所以它可以解决很多问题,这与它的优点有很大关系。
Why use sodium gluconate as corrosion scale inhibitor? First of all, sodium gluconate has many functions and functions, so it can solve many problems, which is closely related to its advantages.
葡萄糖酸钠作为缓蚀剂和阻垢剂,其优点和特点是什么?
What are the advantages and characteristics of sodium gluconate as corrosion inhibitor and scale inhibitor?
1. 明显的协同效应。葡萄糖酸钠是一种“广谱”缓蚀剂和阻垢剂。
1. Obvious synergistic effect. Sodium gluconate is a broad-spectrum corrosion inhibitor and scale inhibitor.
它不仅可用于钼酸盐配方中增强主要缓蚀剂钼酸盐的缓蚀效果,还可用于硅、磷、硼、钨和亚硝酸盐配方中。
It can be used not only in molybdate formulation to enhance the corrosion inhibition effect of molybdate, but also in silicon, phosphorus, boron, tungsten and nitrite formulation.
2. 缓蚀率随温度的升高而增大。对于大多数缓蚀剂来说,随着温度的升高,缓蚀率一般会降低,有时甚至完全失去缓蚀效果。
2. The corrosion inhibition rate increases with the increase of temperature. For most corrosion inhibitors, with the increase of temperature, the corrosion inhibition rate generally decreases, and sometimes even completely loses its inhibition effect.
例如,当水温达到90℃时,主要的磷缓蚀剂六偏磷酸钠和三聚磷酸钠由于水解和降解,几乎失去了缓蚀能力。例如,当水温达到50℃以上时,有机胺类缓蚀剂的缓蚀效果基本丧失。
For example, when the water temperature reaches 90 C, the main phosphorus inhibitors, sodium hexametaphosphate and sodium tripolyphosphate, almost lose their corrosion inhibition ability due to hydrolysis and degradation. For example, when the water temperature reaches above 50 C, the inhibition effect of organic amine inhibitors is basically lost.
而葡萄糖酸钠的抑制率与温度呈反比关系。在特定条件下,它会上升。
The inhibition rate of sodium gluconate was inversely proportional to temperature. Under certain conditions, it will rise.
3.具有良好的络合性能,具有良好的阻垢效果。
3. It has good complexing property and scale inhibition effect.
4、不会造成水质二次污染,且价格低廉。但是,当葡萄糖酸钠作为缓蚀剂时,由于其营养丰富,可以促进藻类的繁殖,这是需要注意的问题。
4. It will not cause secondary pollution of water quality, and the price is low. However, when sodium gluconate is used as corrosion inhibitor, it can promote algae reproduction because of its rich nutrition, which is a problem to be noticed.
