  Jul 05,2014

• Expiry Date:

  Jul 05,2015

• Detailed Description:

  Cas No. :9004-32-4 Quantity: 10000Metric Tons
  Payment Method: LC/TT/NEGOTIATE
  Appearance: White or yellowish powder
  Packing: 25kg net kraft paper bags with PE inner
  Storage: in a light-proof, dry and cool place
  
  
  Main Usage: CMC and PAC can reduce water loss, and increase viscosity in drilling fluid, cementing fluid and fracturing fluid. They play the roles of protecting the wall of well, taking drilling trifles, protecting drilling bit, preventing mud loss and increasing drilling rate. Usage: add to mud directly or glue solution preparation, Addition: 0.1-0.3% in fresh water mud; 0.5-0.8% in salt water mud.
