Application:
Zinc Bromide / Calcium Bromide brine is used as a clear-fluid brine during workover and
completion operations which require densities up to 19.2 lb/gal (2301 kg/M3). It is
blended with calcium chloride/calcium bromide brines to formulate and control density of
various fluids blends.
This brine provides inhibition preventing the hydration and migration of swelling clays and
can be used for packer fluids. Fluids can be formulated with various crystallization points
and are available for special applications and winter use.
For customers' options, the materials are available with Zinc Bromide liquid, Zinc Bromide
powder and Zinc Bromide / Calcium Bromide solution.
It can also be used as after-treatment agent for rayon. It can also be used in medicine and photography. Good completion fluid, cementing fluid and battery electrolyte for offshore oil fields.
Storage:
1) Store in a cool,dry and ventilated house away from moisture
2) Avoid handling or transporting together with acidic or alkaline substances
3) Prevent the material from rain and insolation
4) Load and unload carefully and protect from package damage
5) In the event of a fire,use water,soil or carbon dioxide fire extinguishing media
