properties:
the main composition of dispersant xt-904 is anion polymer. it can adsorb on surface of microparticles resulting in static repulsion, resulting in disperse and preventing sedimentation and coarse turn-back. xt-904 is little foaming, innocuous, non-corrosiveness and non-hazardous.
xt-904 is used as chelant in papermaking coating, building coating, concrete retarder, water reducer, woven and dyeing. its performance can reach to that of sn-5040. adding xt-904 to slurry during grinding process of bolus alba, lime carbonate, pottery clay, titanium pigment, french chalk, barium sulfate, coal-water slurry, etc., the viscosity can be largely reduced and the dispersed slurry is stable.
