DESCRIPTION:
FC-8 is a ferrochrome lignosulfonate with low pH 4 (acidic).
It is dark brown water-soluble product, which complies with OCMA
specification DFCP-8.
APPLICATION:
FC-8 is used as thinner and fluid loss reducer in most
types of water base mud systems. Higher concentration of FC-8 induces
an inhibitive effect upon formation clays. It stabilizes water base
mud systems up to very high temperature.
TECHNICAL INFORMATION:
FC-8 controls flow properties and fluid loss of water
base mud system. When temperature approaches 350°F, FC-8 begins
to degrade. It is recommended to be used when mud is contaminated
with salt or anhydrite. An optimum treatment with FC-8 is 8-10 ppb.
However to deflocculate seawater mud system 4-6 ppb is usually needed
and concentration is lowered to 2-3 ppb when fresh water mud system
is used. Since ferrochrome lignosulfonate is acidic, it is advisable
to adjust the pH value after treating mud system with FC-8. It is
preferable to mix caustic soda and FC-8 together through the mixing
chemical barrel.
PACKAGING:
FC-8 is packaged in 25 kg per multi wallpaper bag.
HAZARD:
Precaution should be taken while handling and mixing.
