STRUB pH-Raiser
Art.-No. 31520
Description
STRUB pH- Raiser is an additive/adjustment agent for the adjustment of the pH- value for the MWF types Biobalanced and Biostabile.
Application
STRUB pH- Raiser is added to alkaline water miscible coolants to raise and stabilize the pH- value. In a cooling water circuit, the pH value can drop due to various inputs and as a result corrosion, instability of the emulsion, performance problems and finally microbial infestation can occur. Caution Do not use with amine-free cooling lubricants. When dosing, it is mandatory to wear protective goggles and gloves.
Dosage
STRUB pH-Raiser is added to 0.1 - 0.2% of the emulsion. It is important to mix the bath volume thoroughly immediately after addition. Afterwards the pH should be checked, it should be 9.0 - 9.2. Otherwise, a further addition must be made.
