Note: 1, the product packaging for 25KG / bag, with three international standards with a membrane valve pocket. Can also be based on user needs packaging.
     2, Apparent viscosity is measured under the condition of total salinity brine 5727mg / l, Ca2 ++ Mg2 + 108mg / l.
The above products are mainly used in oilfield drilling or tertiary oil recovery. They can be used in different specifications according to the characteristics of different blocks in the oilfield (formation temperature, salinity of formulated water, etc.). They can also be used for water treatment of urban sewage and industrial sewage Used as a flocculant
