The all-new CAS particle charge measurement system takes traditional methods of measuring Streaming Potential and establishes a new era of technology and comfort in particle charge analysis. Using industry accepted techniques of titration CAS determines cationic/anionic and acid/base demands of aqueous charge systems. Both Streaming Potential (mV) and pH are measured simultaneous. Making it possible to easily determine isoelectric and flocculation points of a sample.

The FPA is designed to determine the Zeta Potential of fibers according to the Helmholtz-Smoluchowski equation by simultaneously measuring conductivity, pressure and the streaming current potential. The measuring principle is based on the streaming current potential measuring method in a fiber plug. That fiber plug is automatical build up on a screen electrode in the measuring cell of the FPA by (with the help) a vacuum. By periodically changing the vacuum during the measurement the charge clouds absorbed on the fibers are moving with the liquid stream and generating the streaming current potential measured by the screen and ring electrode.

The knowledge of the fiber charge enables a correct and effective dosage of the charged chemical additives. The fiber adsorption of cationic starch, wet strength resin, and many other chemical aids can be easily measured with original samples on-site to optimize the dosage of chemicals in the wet end of the paper manufacturing process.

This instrument has been developed to quickly and accurately determine the influence of chemicals on filtration properties by automatic analysis of drainage and retention of fiber suspensions.

The instrument can be operated very simply from the computer program. This program allows all of the relevant data to be entered. A mixing profile can also be programmed, that can be used to simulate process conditions.

After setting the necessary parameters, you are requested to feed the material to be measured into the instrument, following the mixing profile will run its program. When this is completed, the valve will automatically open and filtration will take place. The amount of filtrate is continuously measured with approximately 5 samples per second. This is displayed in a graph showing the amount of filtrate as a function of time. The computer program can be used to compare all of the graphs by displaying them in the window. It is possible to add all sorts of parameters to the graph, so that comparable graphs are created, such as the dosed amount of chemicals compared to the dehydration velocity.

As machine speeds in paper coating and converting operations steadily increase, papers are stretched more than before, eg. In the printing press, which may result in misregister problems. Because of this, the paper quality has to be assessed prior to upgrading and converting. However, traditional static test methods such as wet tensile, COBB, or HST tests fail to satisfactorily describe the converting behavior. What is needed for quality assurance is more detailed test methods which give close-to-reality results. This is where the WSD Analyzer comes in-to measure the wet stretch dynamics of paper.

It reveals the behavior of paper materials during printing and impregnating processes. The results provide information about the composition of papers or liquids such as inks or impregnating resins, so that industrialists can work on optimization.

Problems caused by deposits in piping and containers are well known and they may lead to Impaired quality reduced run ability and increased costs. Deposits are substances which stick to surfaces, generate agglomerates and therewith congest filters, felts and nozzles which lead to trouble in the production process. Whether or not deposits are generated depends on the method of white water treatment as well as on the successful use of a deposit controlling concept. The measurement of the thickness and pace of growth of those deposits at certain points in the Paper machine is an important requirement to enable an optimal reaction. With the Deposit Control System (DCS) a new, modern and very reliable tool is available in order to help optimizing the conduction of the process. A fast return on investment is ensured.
