ACUMER 2100 Scale Inhibitor and DispersantCarboxylate/sl!onate copoly"er that !nctions as a scale inhibitorand dispersant !or #ater syste"s

Description

ACUMER 2100 is a copolymer that functions as a scale inhibitor and dispersant bycombining strong acid (sulfonate and !ea" acid (carbo#ylate that pro$ide optimal anti%scale&dispersant efficiency'

re-uirements

Che"istry and Mode o! Action

ACUMER 2100 copolymer combines t!o functional groups strong acid (sulfonate and!ea" acid (carbo#ylate that pro$ide optimal anti%scale&dispersant efficiency through thefollo!ing different mechanisms

olubility enhancement by threshold effect+ !hich reduces precipitation

of sparingly soluble inorganic salts (calcium carbonate in particular'

Crystal modification+ !hich deforms the gro!ing inorganic salt crystalto gi$e small+ irregular+ readily fractured crystals that do not adhere!ell to surfaces and can be easily remo$ed during cleaningoperations'

ispersing acti$ity+ !hich pre$ents precipitated crystals or other

inorganic particles from agglomerating and depositing on surfaces'3he sulfonate groups increase the negati$e charge of the carbo#ylategroups adsorbed onto particles and+ by then+ reinforce the repulsion

'er!or"ance

ACUMER 2100 pro$ides superior stabili4ation of calcium phosphate+ 4inc and calciumcarbonate' t also pre$ents calcium sulfate and calcium o#alate scales+ e$en in e#tremep. en$ironments (p. 5%10'

n addition+ ACUMER 2100 is a strong dispersant in "eeping the silt and commonlyencountered inorganic particles suspended and in pre$enting their settling out onto heattransfer surfaces'

Applications

ndustrial 6ater 3reatment ispersant for boilder sludge control

'er!or"ance

ACUMER 1890 is a general purpose scale inhibitor and dispersant' t is effecti$e toinhibit scale deposition on e-uipment surfaces' t acts against precipitation anddeposition of calcium carbonate+ calcium sulphate and other sparingly soluble salts'

ACUMER 1890 is thermally $ery stable' 3here is no !eight loss up to 590;C(thermogra$imetric analysis' t is particularly recommended to use ACUMER 1890 assludge dispersant and scale control polymer in boiler+ e$en in high pressure boilers'

Applications

ndustrial 6ater 3reatment

cale inhibition in open recirculating cooling circuits

ispersant for all types of cooling circuits

ispersant for boiler sludge control
