Ensuring the best retention and drainage performance

Choosing and optimising a retention and drainage system can be bewildering these days, especially with conventional, microparticle, nanoparticle, and other systems available. How can we choose which is the best system for any particular machine or grade of paper, and will it be cost effective? Papertex can provide independent testing, advice and direction to enable you to obtain the best system for your machine.

Retention Services

• Machine surveys
• Laboratory testing
• Product selection to meet mill needs
• Liason between mill personnel and suppliers
• Trial management
• Problem solving and trouble shooting

Papertex has long experience in working with retention and drianage systems, and ensuring that they perform well in conjunction with other wet-end chemistry. We can provide technical and commercial support to both paper mills and chemical companies. Examples of some recent projects have included:

• Three day training programme on retention and drainage in Asia
• Lab studies to evaluate alternative charge control agents and anionic trash collectors
• Advice and support during optimisation of novel microparticle system
• Practical training on lab techniques for testing retention aids
• Laboratory evaluation of alternative retention and drainage aids
• Troubleshooting issues with variable retention results

Papertex is able to offer independent advice and support on all aspects of retention and drainage, from chemical make-up to application at the wet-end. We can also provide unbiased comparisons of alternative retention systems in the lab, or during machine trials, to help in the choice of supplier.

We are also able to supply retention aid and charge control agents. For data sheets, please see our downloads page.
