氨基磺酸水溶液的清洗机理介绍
来源:http://www.jnjrh.com 日期:2019-06-24 发布人:admin
氨基磺酸的水溶液呈酸性,与金属氧化物、氢氧化物碳酸盐反响,构成可溶性盐,因而除去氧化铁锈水垢等。
The aqueous solution of aminosulfonic acid is acidic and reacts with metal oxides and hydroxide carbonates to form soluble salts, thus removing scale of iron oxide rust.
氨基磺酸的性能、清洗机理
Performance and Cleaning Mechanism of Aminosulfonic Acid
氨基磺酸易溶于水,并随着水温的升高,溶解度增大。在清洗过程中,耗费氨基磺酸质量分数与垢层厚度有关,按理论计算,除去1 g碳酸钙垢需求1. 94 g氨基磺酸。依据理论经历,碳酸钙水垢厚度
Aminosulfonic acid is soluble in water, and the solubility increases with the increase of water temperature. In the cleaning process, the consumption of sulfamic acid mass fraction is related to the thickness of scale layer. According to theoretical calculation, 1.94 g sulfamic acid is needed to remove 1 g calcium carbonate scale. Calcium carbonate scale thickness based on theoretical experience
在实践清洗过程中,若清洗液pH上升至3.5时清洗液中的氨基磺酸根本耗尽,需添加氨基磺酸,清洗液才干恢复清洗除垢性能。
In practical cleaning process, if the pH of the cleaning solution rises to 3.5, the aminosulfonic acid in the cleaning solution will be completely exhausted, and the cleaning solution will be added to restore the cleaning and descaling performance.
氨基磺酸清洗液随着清洗液温度的升高,与水垢的反响也越完整。无水的氨基磺酸是白色稳定晶体,它的水溶液稳定性较差。普通控制状况时的温度不高于60%。
氨基磺酸
As the temperature of the cleaning solution increases, the reaction with scale becomes more complete. Anhydrous sulfamic acid is a white stable crystal with poor stability in aqueous solution. The temperature under general control is not higher than 60%.
氨基磺酸对橡胶塑料、尼龙等均无腐蚀作用,但对金属有一-定的腐蚀性,因而在清洗时,针对不同的材质需在清洗液中添加适宜的缓蚀剂。
Aminosulfonic acid has no corrosive effect on rubber plastics and nylon, but has a certain corrosivity to metals. Therefore, suitable corrosion inhibitors should be added to the cleaning solution for different materials.
为进步清洗效果,在氨基磺酸清洗液中添加具有润湿、浸透、乳化和增溶作用的外表活性剂。供选择的有:TX-10、十二烷基苯磺酸钠等阴离子型或非离子型外表活性剂,质量分数-般取0. 1%3)。
In order to improve the cleaning effect, the surfactant with wetting, soaking, emulsifying and solubilizing effects was added to the aminosulfonic acid cleaning solution. Selected are: TX-10, sodium dodecylbenzenesulfonate and other anionic or non-ionic surfactants, the mass fraction - generally 0.1% 3.
因聚丙烯酸不但能吸附CaSO4 CaCO3及粘泥,而且在低pH时有较好的分散作用,可进步钙垢的溶解才能。因而在氨基磺酸清洗液中还要参加0.1%左右的聚丙烯酸作为分散剂。
Because polyacrylic acid can not only adsorb CaSO4 CaCO3 and clay, but also have better dispersing effect at low pH, which can improve the dissolution ability of calcium scale. As a result, about 0.1% polyacrylic acid should be added to the aminosulfonic acid cleaning solution as a dispersant.
