氨基磺酸与水能够产生什么样反应?
来源:http://www.jnjrh.com 日期:2019-08-09 发布人:admin
氨基磺酸与水反应,很容易生成与盐酸、硫酸同等的强酸性水溶液——氨基磺酸溶液,可去除铁、钢、铜、不锈钢等材料制造的设备表面的水垢和腐蚀产物。
Aminosulfonic acid can easily react with water to form strong acidic aqueous solution, which is the same as hydrochloric acid and sulfuric acid. Aminosulfonic acid solution can remove scale and corrosion products on the surface of equipment made of iron, steel, copper and stainless steel.
氨基磺酸与水配比:
Aminosulfonic acid and water ratio:
1、氨基磺酸水溶性:146.8 g/L (20°C);
1. Water solubility of aminosulfonic acid: 146.8 g/L (20 degree C);
2、氨基磺酸:水=1:125,即把氨基磺酸溶解在蒸馏水中(即称取8g氨基磺酸溶于1000mL蒸馏水中),就可配制成0.8%的氨基磺酸溶液;
2. Aminosulfonic acid: water = 1:125, that is, dissolved in distilled water (that is, 8 g of sulfamic acid dissolved in 1000 mL distilled water), can be prepared into 0.8% sulfamic acid solution;
3、氨基磺酸在0℃时溶于6.5份水,80℃时溶于2份水;
3. Aminosulfonic acid dissolves in 6.5 phr of water at 0 C and 2 phr of water at 80 C.
氨基磺酸
4、氨基磺酸在25℃,1%溶液的pH为1.18,相对密度2.15.
4. Aminosulfonic acid at 25 C, the pH of 1% solution is 1.18, and the relative density is 2.15.
氨基磺酸水解速率:
Aminosulfonic acid hydrolysis rate:
氨基磺酸溶于水后,其水溶液加热至60度以上时,将水解成硫酸盐:HSO3NH2+H2O=NH4HSO4,其水解速率与其浓度、温度和pH值成函数关系。
When sulfamic acid is dissolved in water and heated to above 60 degrees, it will be hydrolyzed into sulfate: HSO3NH2+H2O=NH4HSO4. The hydrolysis rate is a function of its concentration, temperature and pH value.
氨基磺酸溶解度:
Aminosulfonic acid solubility:
氨基磺酸易溶于水,并随着水温的升高,溶解度增大,如下表格:
Aminosulfonic acid is soluble in water, and the solubility increases with the increase of water temperature, as shown in the following table:
温度(0C)
Temperature (0C)
0, 20 ,40 ,60 ,80
0, 20, 40, 60, 80
重量(%)
Weight (%)
12.817.5722.7727.0832.01
12.817.5722.7727.0832.01
有此表格可知,氨基磺酸溶解度随温度的升高,与水垢的反应也越完全,所以可用于以钢、铁、铜、铝合金制成的设备内部的水垢、铁锈进行清洗,提高设备热效率,清洗时适当提高清洗液温度、添加适量的表面活性剂和分散剂可提高清洗效果。
It can be seen from this table that the solubility of aminosulfonic acid increases with temperature, and the reaction with scale is more complete. So it can be used to clean scale and rust in equipment made of steel, iron, copper and aluminium alloy, improve the thermal efficiency of equipment, properly raise the temperature of cleaning solution, add appropriate surfactant and dispersant when cleaning. It can improve the cleaning effect.
