So-called "vanity
sizing" is said to be creeping into stores with retailers cutting clothes larger but keeping the same size.
The new starch substantially increases the
sizing efficiency of ASA.
They also provide proper prediction domains for
sizing. The simplified models provide some insight into the difference between esterified sizes and fortified sizes for the relationships between paper
sizing and the factors of pH, temperature, water hardness, and fortification.
What is the effect on alkyl ketene dimer (AKD)
sizing when aspen high-yield pulp is substituted for hardwood kraft pulp?
New
sizing compounds have now been synthesized to overcome these problems.
As expected,
sizing increased markedly with dosage over the range of dosage studied.
S-cutter press-side sprue/runner return granulator produces uniform particle size with minimal fines at low rotational speed of 30 rpm without a
sizing screen.
More effective internal
sizing, including ASA's on-machine curing capability, means less surface
sizing, which improves printability.
In this work, the researchers studied the effects of impulse drying on AKD retention and on the efficiency of
sizing. Impulse-pressed handsheets beaten to 25[degrees]SR or 40[degrees]SR were prepared.
The two most important parameters to consider in
sizing a dryer are air flow (cubic ft/min or cfm) and process-air temperature.
As furnishes become more contaminated, the higher
sizing efficiency of ASA is also preferential over using increasingly more AKD to achieve the same result.
The correct granulator selection matches the rotor and knife design, knife clearances, rotor speed, and screen
sizing to the infeed material's properties and physical form.
