Mechanical Treatment of Metals

On the surface of vapour phase degreased metals 12 - 14 mg/m of organic carbon was detected, while on the alkaline cleaned metal surface 6-8 mg/m of organic carbon was detected. [Pg.88]

For water-based cleaning three types of systems are known [Pg.88]

The acid phosphate systems will be considered in Section 3.2.5 on the chemical conversion of surfaces. [Pg.88]

This cleaning method is commonly used in metal industries. The process consists of cleaning parts in a mixture of surfactant, sodium or potassium hydroxide, and combinations with sodium carbonate, sodium silicate, borates and in special cases sodium gluconate. [Pg.89]
