What is praestol a 3040 L?

Praestol A 3040 L and Praestol A 3075 L are two emulsion anionic polyacrylamides with different degree of hydrolysis and molecular weight. They are widely used in mineral processing, water treatment and oil fields. The emulsion anionic polyacrylamide (Praestol A 3040 LPraestol A 3075 L) can be replaced by ASIAFLOC EM2007 and ASIAFLOC EM3018

What is the difference between praestol 2540 and 2515?

As can be seen, although Praestol 2540 is a medium anionic polymer stronger than Praestol 2515, which is a weak anionic polymer, the kaolin suspension treated with these two different polymers reaches the zero zeta potential at approximately the same concentration, which is about 10-3 %.

What is praestol 2540 & chinafloc a2520?

Praestol 2540 is a kind of anionic flocculant with very high molecular weight can be used for wastewater treatment and mineral processing ,Chinafloc A2520 can replace of it totally with high performance. 1.

What is the optimum coagulant dose of praestol 2515- tetranyl at-7590?

Thus, when the complex Praestol 2515- Tetranyl AT-7590 and complex Praestol 2540- Tetranyl AT-7590 were used, the optimum coagulant dose (cζ) was 7.10-6 %, a value which is about two orders of magnitude smaller than that associated with the use of polymers Praestol 2515 and Praestol 2540.

What is the maximum sedimentation velocity of praestol 2515- tetranyl at-7590?

Therefore, when the complex Praestol 2515- Tetranyl AT-7590 was used, a maximum sedimentation velocity of 8.56.10-2 mm/s was obtained corresponding to an optimum coagulant dose of 2.10-6 % while when only Praestol 2515 was used, the maximum sedimentation velocity was 2.78.10-2 mm/s corresponding to an optimum coagulant dose of 0.5.10-3 %.

What is anionic emulsion polyacrylamide (CPAM)?

Anionic emulsion polyacrylamide (CPAM for short, CAS number: 9003-05-8) is a linear polymer product made of monomer and acrylamide tools. It is soluble in water, but the dissolution rate is slow, non-toxic and odorless.
