Fiber Fundamentals
This type of pulp is used for strength generation and structure
What is Softwood?
The primary mode of action for defibering in a repulper
What is mechanical action?
The primary purpose of refining
What is strength generation?
Another name for Kymene
Permanent Wet Strength Resin
These two water sources are used in the papermaking process
What is fresh and treated water?
This is what MPD stands for
What is Materials Process Delivery?
Two kinds of broke on a papermachine
What is machine broke and bleached broke?
This brand has making instruction limits for PFR
What is Charmin?
BOM chemicals used in tissue papermaking
What is TWSR and Redibond?
The recommended Coagulant ppm/Flocculent ppm ratio in our DAFs?
What is 1:3?
The most expensive fiber
What is broke?
This piece of equipment on a pulper ensures inform particle size is allowed forward in the process
What is an extraction plate?
These are two negative consequences of over refining
What is loss of tensile strength and poor drainage?
The chemistry with the highest spend in papermaking
What is PWSR?
DAILY DOUBLE!
Hardness can have these three impacts to the papermaking process
What is scaling, chemical retention, and Yankee glue coating?
Fatty acid and oils
What is pitch?
This is graphed on a pulper curve
What is Tensile vs Pulping Time?
DAILY DOUBLE!
These three factors are used to calculate refining intensity
What is net kW, refiner RPM, and bar edge length?
Most chemistries are added to react with fiber. This chemistry is the exception.
What is CMC?
The sequence of transformations in the DAF
What is DAF feed > Coagulant Addition > Flocculent Addition > Dissolved Air Injection > Floatation > Scraping sludge/reclaiming treated water?
These three shades of blue are new ways to categorize NSK
What is Indigo, Cobalt, and Sapphire?
These two chemistries are used in stock prep repulpers to process broke
What is sodium hypochlorite and oxone?
Historically, this fiber type has been refined with softwood for savings
What is Northern Hardwood Kraft (NHK)?
This happens to TWSR in the tissue process when pH drops below target
What is permanent wet strength?
The mechanism for how coagulant and flocculant work together in the DAF
What is Patch/Bridge model?
