Description
PRODUCT STABILITY
This can be observed by simple adjustment of product pH. Using an alternative solvent based PMA, impurities readily precipitate, creating sediment and changing product appearance. PMA stability is maintained throughout these adjustments. With PMA you choose higher quality and are less likely to experience formulation stability problems commonly associated with other solvent based PMA’s.
HALOGEN TOLERANCE
PMA is at least as halogen tolerant as other based PMA’s and will provide maximum flexibility for controlling microbial activity in a cooling system.
PMA CALCIUM CARBONATE & CALCIUM SULFATE INHIBITION PROPERTIES
Simple jar testing is frequently used to assess additives for deposit control properties. It reveal the superior performance properties of PMA versus an alternative solvent based PMA.
Under severely stressed conditions (e.g high cycles of concentration), process water can become supersaturated with respect to calcium sulfate. PMA offers an additional feature of effectively controlling calcium sulfate precipitation where other PMA’s do not.
CALCIUM CARBONATE DYNAMIC TUBE BLOCK TEST
Dynamic tube block testing is another technique used to assess the properties of additives, in this case their efficiency in supressing crystal growth at surfaces. Data from experiments which measure how pressure builds in stainless steel capillary tubes when solutions of anions and cations are mixed together, in the absence and presence of inhibitors. Clearly, PMA is able to moderate calcium carbonate growth long after alternative solvent PMA has been overwhelmed. Polymers are tested at 1 mg/L as solids.
FEATURES/BENEFITS:
