BELCLENE 283
BELCLENE 283
Belclene 283 is a cost effective alternative to polyacrylate-based calcium carbonate antiscalants, for low to moderate LSI cooling applications, food applications, and Kraft pulp digester treatment.
ApplicationS of Belclene 283:
In cooling water formulations, Belclene 283 provides:
-Superior calcium carbonate scale inhibition when used alone or in combination with phosphonates.
-Both threshold inhibition and crystal modification.
-Stabilization of zinc in solution to give better corrosion control.
-Contains no phosphorus or heavy metals, making it ideal for all-organic programs.
Benefits of Belclene 283:
In formulations for use in food plants, Belclene 283 also provides:
-FDA approval for use in non-contact cooling and retort waters.
-Halogen stability. In pulp mill product formulations, Belclene 283 also provides:
-Superior calcium carbonate scale inhibition in Kamyr digesters.
-FDA approval for use in pulp production where the paper that may contact food.
-Significant reductions in plant downtime for cleanings and repair.
Belclene 283 is a very cost effective alternative to polyacrylate based calcium carbonate antiscalant.
Belclene 283 is used for Low LSI cooling, food industry, and Kraft pulp digester.
Belclene 283 contains a chemical formula with various advantages, especially in cooling water, namely:
