Uses Area of NIPACIDE CI 15:
In Metalworking Liquid Protection:
NIPACIDE CI 15 is recommended for the control of bacteria and fungi in soluble and emulsifiable type aqueous metalworking fluids.
For the maintenance of a nonfouled system, use NIPACIDE CI 15 at 32 fluid ouncesNper 1000 gallons of emulsion (2 Ibs.) every 4 weeks or 3-154 fluid ounces per 1000 gallons emulsion (2-10 Ibs.) every 8-12 weeks.
For a noticeably fouled system use an initial dose of 64-154 fluid ounces per 1000 gallons emulsion (4-10 Ibs.) to be followed by subsequent maintenance dosages depending upon the treatment interval noted above.
A higher dosage range and/or increased fi-equency of treatment may be required depending upon rate of dilution of the preservative with makeup fluid the nature and severity of contamination, level of control required, filtration effectiveness, system design, etc.
The preservative should be dispensed into the use-dilution of the metalworking fluid using a metering pump and uniformly dispersed throughout the system.
In Metal Cleaning Fluid Preservation:
NIPACIDE CI 15 is recommended as a preservative for use in the manufacture and use of alkaline acid, and emulsion based metal cleaning fluids typically used in electroplating, phosphatizing, galvanizing and general metal cleaning operations.
For addition to a metal cleaning concentrate, add NIPACIDE CI 15 at a level to ensure that the final use-dilution fluid will contain 425 to 1,675 ppm product (6.25 to 25 ppm active isothiazolones).
For direct addition to a fouled system, add 54-214 fl. oz. (3.6-14.1 Ibs.) of NIPACIDE LX microbiocide to each 1,000 gallons of use dilution metal cleaning fluid every 3-4 weeks to provide 425-1,675 ppm product (6.25-25 ppm active isothiazolones).
A higher dosage range and/or increased frequency of treatment may be required depending upon rate of preservative with the make up fluid, the nature and severity of contamination, level required, filtration effectiveness, system design, etc.
The preservative should be dispensed into the use-dilution metal cleaning fluid using a metering pump and uniformly dispersed throughout the system
