ACA Systems 推出全新超⾼剪⼒粘度仪 ACA AX100

ACAV AX100 Ultra high shear viscometerACA Systems is celebrating the 30 years in the business at PulPaper Exhibition in Helsinki 29.5 – 31.5. The company launched as well new innovative analyzer for paper & board coating optimization, ACAV AX100.

ACAV viscometer was a breakthrough in 90’s and due to its ability to describe runnability of a coating color, the measurement became in industrial standard for paper and board coatings.

Now it is time to launch brand new ACAV viscometer as technology has enhanced and the customer demand is clearly picking up.  The new user-friendly analyzer makes the coating development and quality control easier than ever.

Due to ultra-high shear rates provided by the analyzer, the rheology of the coating color can be studied in the real process conditions, having a very good correlation to actual coating runnability. This is extremely important for example in sustainable water based barrier coatings that are typically very challenging in terms of runnability.

The first unit was sold to a global leading coated board manufacturer in Finland.

 

 

 

Core benefits of ACAV AX100

Simulating real coating conditions

  • Coating colors are rheologically complex materials.
  • Their viscosity is strongly dependent on shear rate. Modern highspeed coaters generate shear rates > 1 000 000 1/s
  • ACAV AX 100 measures viscosity at shear rates > 1 000 000 1/s whereas low shear rheograms that are commonly used in the industry demonstrate only low shear viscosity portion and can be extremely misleading when it comes to the prediction of coating performance or runnability on high speed coaters.

Speed up coating development

  • Unique and tailored measurement head design provides excellent contact with the web and eliminates the leakage air, dust and other disturbances.
  • Generated stable air flow leads to very high correlation (> 0,95 R2) between ACA Permi and any lab standard (Gurley, Bendtsen, Coresta, delta P…)
  • Roll to roll data and color maps with high statistical confidence to identify uniform and non-uniform rolls.
