S-WELD NEUTRALISER Neutralising Solution for Acidic Pickling Paste

  • S-Weld Neutraliser is a alkaline solution for the neutralisation of acidic pickling waste. It contains an in built pH indicator to provide a visual colour change when neutralisation of spent acidic waste has been completed.
  • S-Weld Neutraliser allows users of pickling paste and other acidic metal treatment products to comply with pH requirements of trade waste water regulating authorities.
  • Appearance : dark pink alkaline liquid; mixes with water
  • pH : 12.0 ± 0.5
  • Specific gravity : 1.14 - 1.16
  • Solubility in water : miscible

1) Neutralisation of retained acidic waste

 For every litre of spent pickling waste, add approximately 1.7 litres of S-Weld Neutralizer. The
 S-Weld Neutraliser on contact with the spent acid waste will go clear. Keep on adding S-Weld
 Neutraliser solution till a faint pink coloration exist.

 If neutralisation has not occurred with the initial dosage, then add additional quantities of
 S-Weld Neutraliser at 100ml per litre of waste until colour change is observed.

2) Diagnostic Use

 After washing the pickling gel away and while still wet, spray the S-Weld Neutraliser solution
 directly onto the area where the pickling gel was applied, in particular in corners and crevices. If
 residual acid is present an effervescent reaction will occur. Flush with water thoroughly once
 the effervescence has stopped.

 Avoid contact with skin or eyes.
