Oil Drilling & Exploitation Grade Xanthan Gum, 1. Function Introduction: Rigchina Oil Driling & Exploitation Grade Xanthan Gum is specially produced as mud additive for oil drilling and exploitation. Being an environment friendly and high efficiency mud additive, RIGCHINA Oil Drilling & Exploitation Grade Xanthan Gum has an excellent tolerance to the changes of temperature, acid, alaline and, it can extremely increase the products penetrating ability and suspending perform to small solid materials, and reduce the pressure loss during xanthan gum can not only fasten the well bore,but decrease the damage to oil can also greatly raise the efficiency of drilling, repair and completion. As a biotype oil driver, RIGCHINA Oil Drilling & Exploitation Grade Xanthan Gum can improve oil extraction rate and utilization factor of natural more important point is that it can furthest protect natural environment. 2、Specifications： Specifications RC***0 RC***0 Particle Size (Mesh) *0 PH Value (1% Solution) 6.**8.0 Loss on Drying（％） ≤*3 Ashes（％） ≤*3 Pyruvic Acid（％） ≥1.5 1% Solution Viscosity（ cps ） ********0 ********0 Shearing Ratio ≥6.0 ≥6.5 Rheological Property ∠ 0.5 ∠ 0.5 Yield Point ≥*0 1bs/**0ft 2 ≥*0 1bs/**0ft 2 Salt Tolerance at 3 rpm ≥*2.5 ≥*2.5 3.
