Description
~CMC stands for carboxymethyl cellulose. However, CMC is more
correctly the sodium salt of carboxymethyl cellulose.CMC has
the ability to impart viscosity to aqueous
solutions. CMC is pseudoplastic ,thixotropic and
essentially non-thixotropic rheology by nature .By choosing the
right cellulose gum type, the formulator has the ability to achieve
the desired rheology for any aqueous system, including suspensions
and emulsions. Besides controlling the rheology, CMC is also known
for its excellent water retaining capacity.
~Oil Drilling CMC. CAS NO: ********4
~Slurry with CMC would form thin but hard filter cake with low
permeability, reducing water loss. Adding CMC into slurry will
endow the drill with low initial gel strength, making the slurry
give off the gas inside and abandoning the waste into the slurry
pit. Same as other suspending dispersion, the drill slurry has an
existing period which will be stable and extended after adding
CMC.
Slurry with CMC is seldom affected by the bacterium and requires no
high PH value or corrosion resistant.
Slurry with CMC has excellent stability and will still reduce the
filtration loss under **0℃or above.
For CMC of LV and HV ,Maoyuan is one of the main suppliers to
Drilling companies in domestic and international.
Oil & Gas Drilling PAC. CAS NO: *******0
~Our PAC products are high-tech products. As anionic cellulose
ether, it features high purity, high replacement and well
distribution and can be taken as thickener, rheology modifier and
fluid loss agent. HV and LV PAC are indispensable products in
slurry combination. The application experience of CNPC, CNOOC,
Daqing Oilfield, Shengli Oilfield, oil mining enterprises in Middle
East and Europe witnesses the excellent performance as well as
stable and reliable quality.
High quality PAC is white flowing powder and the water solution is
transparent viscous liquid. As water soluble polymer, it can be
able to be thickener, rheology control agent, adhesive, stabilizer,
protective glue, suspending agent and water retaining agent.
In oil drilling industry, PAC is a good kind of slurry agent
and fluid material, with high mud yield and excellent salt
resistance. To fresh-water mud, seawater mud and saturated brine
mud, PAC is an excellent filtration reducer ,superior to increase
viscosity and high temperature resistance (**0℃). Besides, it can
formulate completion fluids with various densities .even there is
more calcium chloride, it still can keep the completion fluid with
certain viscosity and lower filtration.
Our HV and LV PAC products not only meet the standards of
OCMA and API *3A,but also able to step over these standards if you
have a special demand.
Oil Drilling CMS CAS NO: ********4
~CMS is a kind of modified starch with carboxymethyl
etherification, performance is better than that of carboxymethyl
cellulose (CMC) with competive price. It is the best products to
replace the CMC.
CMS has a good performance in adhesion, thickening, water
emulsion, suspension, dispersion, etc. As mud stabilizers in oil
drilling and water retention agent, it could reduce the water loss,
improve the stability of the coalescence of clay particles in
drilling fluid role.
Flotation CMC CAS NO: ********4
~CMC is widely used as an agent in floating
seperation in the mining industry .CMC is the pellet binder and
flotation inhibitor, It is a kind of ore forming binder which is
indispensable for making pellets,because it can improve the
properties of wet ball, dry and roast pellets.
Pellets with good ball cohesiveness have good performance of
antiknock, compression and falling,at the same time it can improve
the grade of pellets.
CMC is also a knid of adjusting agent in the process of
floatation，in silicate gangue and copper lead separation, It is
mainly used as inhibitor ,sometimes used as a slurry
dispersant.
