I need a dirt particle analyzer software for deinked pulps? Is there anyone who can help me?
Or how can i supply software?
You can contact University of Quebec, Trois-Rivieres, Canada or CTB France for ERIC testing equipment or you can buy one.Following
Mustafa Çiçekler added an answer:Which enzyme gives the best result in deinking?
My work is about deinking and I will use enzyme before deinking process. Which enzyme does give the best result in deinking? I am waiting for your suggestion.
Thanks for your interesting, Dear SanjayFollowing

Aleksei Guzev added an answer:How do print machine engineers control the color when they make a printing device?Even though we do a good color management for a printing device with a certain kind of paper, for some in-gamut color, the delta E is still bigger than expected. Could anyone tell me how the engineers control the color in a new printing device and what lead to this result?
There is a lot of tools engineers use. What do You mean by "delta E"? Was it difference between print and original? Maybe it was the difference between prints of different machines of the same model?Following
Aleksei Guzev added an answer:Whats the best way to prepare RGB files for CMYK printouts?I need to prepare colour tiles (approx 3*3mm with a uniform color) that were stored in sRGB color space for printing out on a litho printing machine (CMYK U.S. Web Coated (SWOP) v2).
However, when I use the seperate+ plugin for GIMP to change to CMYK, the output changes the colors sometimes dramatically. I'm aware that the CMYK color space is more limited than the RGB space, but is there any way to keep the colors more consistent?

Humphrey Lumadede Mudoga added an answer:Can someone advise me on making slurry for manufacture paper from sawdust?
I am try to do a laboratory scale manufacture from sawdust and I need to know the parameters and chemicals I should use and in what ratio? Does Sawdust loose its lignocellulossic structure and thus may need a strong binder for paper or soft tissue making? Please how does one make a slurry for paper manufacture using sawdust as the raw material? Humphrey
Thank you for your anwers
F. Louis Floyd added an answer:Could we correlate the rheological properties of a conducting ink with spreading and dry ink on substrates?
I want to correlate the rheological properties of ink with spreading and drying behavior of ink on substrates. Please suggest any good references which explain the rheological properties with drying and spreading of ink on solid substrates.
Any liquid containing magnetic or conductive pigments or fillers exhibits more complex rheology than liquids not containing such particles. The attractive forces between such particles are considerably stronger than for non-magnetic and non-conductive particles, and usually exceed the repelling forces usually introduced by the addition of surfactants or dispersing agents.
These forces can be measured by
- measuring viscosity as a function of shear rate, starting at zero rate. The yield strength is the force required to see the first rotation of the spindle, and is quite sensitive to attractive forces between particles.
- In addition, any shear-thinning (pseudo-plasticity) will also reflect those forces.
- A third technique is to measure the viscosity response for the up-curve (increasing shear rate) with the reversed down-curve (decreasing shear rate). The gap is called the hysteresis for the system, and is again sensitive to attractive forces.
These three properties well-define the behavior of systems filled with particles that have attractive forces that tend to exceed the repelling forces usually introduced by the addition of surfactants or dispersing agents.
I hope this is some value to you. The more specific you can phrase your questions, the better we all can respond to your interests.
