To be suitable for lower solid mud, has clear action on stop falling anything from caving and stop up leak,it has good close water base of interchangeability, thixotropy, lubrication, dilatancy, suspension property and similar to white powder, it is also or be used for oil and gas well drilling and civil-engineering include applied drilling fluid system for horizontal directional drilling (HDD), applied fluid solutions for diaphragm walls and piles, lubrication fluids for micro tunneling or pipe jacking, drilling fluids for water well, exploration and mining, fluids solution for shield tunneling.
The gel is colorless with super dispersibility, high transparency,
need polar activator. Applicable to low and middle polar solvent systems.
Used in transparent paints, printing inks, cosmetics, sealants,
nanometer composite material.
