a) Suctioned in water by using a vacuum funnel, feeding should be
uniform, so that the powder can be uniformly dispersed in water,
otherwise it will form "fisheye".
b) After the addition of powder, using cement truck or circulating pump cycle for 30-45 min.
c) The prepared liquid standing for 2 h, so powders can be fully swollen in water.
Features
General
JF011-50A is the most widely used thickener,
which has strong thickening capacity, good temperature and shear
resistance capacity, and low leak off, low residue content. It can meet
the demands of different well depth and amount of sands.
Application
a) Suctioned in water by using a vacuum
funnel, feeding should be uniform, so that the powder can be uniformly
dispersed in water, otherwise it will form "fisheye".
b) After the addition of powder, using cement truck or circulating pump cycle for 30-45 min.
c) The prepared liquid standing for 2 h, so powders can be fully swollen in water.
