Summary
DSBF-470 is specially manufactured for sulfate-reducing bacteria (SRB), tjkij gin bacteria (TGB), which wildly exist in oilfield. The product is a broad-spectrum biocide synthesized by cationic long-chain polymer, surfactants and stabilizer. It can be widely used in infection water for oil flooding, drilling mud, effluent water, and recycling water in petrochemistry.
Properties
Strong bacteriercidal ability to SRB and iron bacteria
Bacteriostatic time can last over 1 month.
Low price and dosage
Nontoxic, colorless, odorless, and non-stimulation to skin
Resistant to high temperature , effective below 400℃
Resulting in non-resistance to biocide for long-term using
Resistant to interference of organic, non-corrosive to metal
No foaming, soluble in water, degradable, and no environmental pollution

Bactericidal mechanism
The electropositive and electronegative adsorption to bacterium and viruses can restrain the division and reproduction of bacterium and viruses. The twining effect of the polymerized long chain can suffocate the microorganisms. The special physical bactericidal mechanism results in non-resistance to biocide for the bacterium.
Strong Exterminate Action to Anaerobic Bacteria
DSBF-470 can exterminate the anarerobic bacteria in oilfield, the test completed by Daqing Oil Industry Crude Oil and Petroleum Products Quality and inspection Center shows that DSBF-470 has a good biocidal effect to the anaerobic bacteria, the relative data are in the table below.
