xanthan gum oil drilling grade
Detailed Description
Xanthan gum have the performance of hydrodynamication,emulsion,suspension,excellent tolerance to high temperature,sacid, alkaline and salt,against pollution and protect environment,xanthan gum has obvious advantages compare with other conglomerates for oil drilling.Keep high viscosity in low longitudinal shear,let the low thickness of drilling liquid can float solid physicals,this is very important to sea drilling. Xanthan gum is widely used in sea drilling, land drilling, horizontal drilling.
a) A high degree pseudo-plasticity over board shear rate
b) Stable in both acidic and alkaline solutions
c) Stable in high temperature
d) High concentration of various salt
e) Excellent suspension for insoluble solids and oil droplets
f) Extremely effective emulsion and foam stabilizer
g) Drilling mud agent:well heatproof, anti-salt, shearing dilution
and particle suspended function
h) At saturation salt water and long-time stability
