Description
The dispersant KEBOSOL PM enables a successful alkaline cleaning of the evaporators scaled with calcium oxalate deposits or mixed scales of calcium oxalate and silicates. When adding KEBOSOL PM as dispersant to alkaline and neutral solutions, in favourable cases, evaporators, preheaters and pans can be cleaned without using acid. Other fields of application are the dispersion of mainly organic scales and the stabilization of water hardness (Ca2+ and Mg2+) if hard water has to be used for the chemical cleaning. KEBOSOL PM contains a combination of polymeric compounds with dispersing and sequestering properties in an optimum blend.
Benefits
- Free from phosphorous, not volatile at high temperatures and practically resistant to hydrolysis.
- Has the ability of dispersing calcium oxalate scales as well as scales with a high content of organic substances and of removing them partly from the tube wall. During this process the compounds of calcium, magnesium, iron and other heavy metals contained in the scales are partly transformed into water soluble complexes.
- The removal of scales by sodium carbonate solutions is additionally based on a substitution effect so that in presence of KEBOSOL PM the active surfaces of the calcium carbonate being formed are covered with the dispersant and a new agglomeration is avoided.
- When in addition a surfactant (e.g.KEBOSOL VD) is used to reduce the surface tension, this process will be intensified.
Dosing, Addition
In general the dosing rate of KEBOSOL PM to alkaline solutions amounts to 0.5 %.

Storage
In closed original packages KEBOSOL PM is storable for at least two years. The intensification of the colour in case of a longer storage period does not have any influence on the quality and efficiency of the product. Protect from frost (enormous increase in the viscosity).
Notes. References
In case of proper application KEBOSOL PM complies with the requirements of the German Food and Feed Code (LFGB, revised version by announcement of 15.09.2021). The organic raw materials contained in KEBOSOL PM are exclusively of petrochemical origin and are therefore neither BSE-endangering (bovine spongiform encephalopathy) nor genetically modified.Kosher Certification No.: 81173637, company number: 0351
Os produtos apresentados em nosso site são apenas uma seleção de nossa linha completa de produtos. Não há um produto universal para a remoção rápida de impurezas. Algumas podem ser bem removidas com produtos alcalinos, enquanto outras respondem melhor a produtos ácidos. É altamente recomendável buscar uma consulta detalhada antes de iniciar a limpeza, devido à grande variedade de problemas de limpeza possíveis e à ampla gama de aditivos, inibidores e soluções de limpeza prontas que oferecemos.<br /> O mesmo se aplica a inibidores, antiespumantes, inibidores de acúmulos, produtos anticorrosivos, inibidores de decapagem, etc. Cada equipamento, material, produto e tipo de água de caldeira/refrigeração utilizada apresenta desafios individuais e distintos. Estamos bem preparados para lidar com esses desafios.
