碱性除油剂的主要成份及其作用：

The main components and their functions of alkaline deoiling agent:

1、氢氧化钠(NaOH ):它是一种强碱，皂化作用较强，但它的润湿作用和乳化作用较差，所以它不是一种好的去污剂。氢氧化钠本身水洗性较差，对许多有色金属有腐蚀性，并使黄铜变色。

1, sodium hydroxide (NaOH): it is a strong base, saponification is strong, but its wetting and emulsifying function is poor, so it is not a good detergents. Sodium hydroxide itself has poor washability, corroding many nonferrous metals and discoloring brass.

2、碳酸钠(Na2CO3 ):它具有良好的缓冲作用，然而其水解后碱性不高，如0.5%的水溶液pH 为11.30碳酸钠本身的去垢作用也较差，水洗性也不好。

2, sodium carbonate (Na2CO3): it has good cushioning effect, however, the alkaline hydrolysis is not high, such as the pH 0.5% aqueous solution of 11.30 sodium carbonate as the detergent action itself is also poor, washing is not good.

3、磷酸三钠(Na3PO4 ·12H2O):它具有良好的缓冲作用，0.5%的水溶液的PH为11.8。磷酸三钠具有一定的表面活性作用，它的水洗性极好，还有一种三聚磷酸钠效果更好。

3, three sodium phosphate (Na3PO4. 12H2O): it has a good buffer effect, and 0.5% of the aqueous solution of PH is 11.8. Three sodium phosphate has a certain surface activity, its water washing is excellent, and a kind of sodium tripolyphosphate is better.

4、硅酸钠:硅酸钠本身具有较好的表面活性作用，当它与其他表面活性剂组合使用时，它是碱类中最佳的润湿剂、乳化剂和分散剂。偏硅酸钠还广泛地应用在有色金属去油中作缓蚀剂。

4, sodium silicate: sodium silicate itself has good surface activity. When it is combined with other surfactants, it is the best wetting agent, emulsifier and dispersant in alkali. Sodium metasilicate is also widely used as a corrosion inhibitor in the deoiling of nonferrous metals.

5、乳化剂:乳化剂是一种表面活性剂，一种是憎水性的，一种是亲水性的。

5, emulsifier: emulsifier is a surface active agent, one is hydrophobicity, the other is hydrophilic.
