  • Publication number: 20240247439
    Abstract: Methods and compositions for inhibiting scale in papermaking processes are provided. The methods may include adding an effective amount of a terpolymer composition to an aqueous medium in the papermaking process. The terpolymer may include various monomers, such as maleic anhydride, acrylic acid, and methacrylic acid. As non-limiting example, the weight average molecular weight of the terpolymer may be from about 5,000 Da to about 20,000 Da.

  • Publication number: 20220251781
    Abstract: A method of treating brown stock in a brown stock washing process is provided. The method includes measuring a refractive index of a brown stock; and dosing an additive to the brown stock according to at least the refractive index of the brown stock. A system for controlling dosing of an additive to a brown stock washing process is also provided. The system includes a refractive index measurement device; a controller configured to receive data provided by the refractive index measurement device and transform the data into additive addition output instructions; and an additive delivery unit configured to receive and execute the additive addition output instructions from the controller.

  • Publication number: 20170254022
    Abstract: A method of preparing a stable dispersion of flocculated filler particles for use in papermaking processes comprises use of an anionic first flocculating agent to an aqueous dispersion of filler particles, followed by addition of a second anionic flocculating agent to the dispersion and further optional shearing of the resultant filler flocs to the desired particle size resulting in shear resistant filler flocs with a defined and controllable size distribution.

  • Patent number: 8999111
    Abstract: The invention provides methods and compositions for increasing the strengthening effect of a starch coating on paper. The method involves contacting the starch with a synthetic polymer before the starch is cooked. This changes how the starch gelatinizes and how the polymer gets distributed on the paper resulting in greater paper surface strength.

  • Patent number: 8778140
    Abstract: A method of preparing a stable dispersion of flocculated filler particles for use in papermaking processes comprises use of microparticle prior to, simultaneous to, and/or after addition of a first flocculating agent to an aqueous dispersion of filler particles, followed by addition of a second flocculating agent to the dispersion and further optional shearing of the resultant filler flocs to the desired particle size resulting in shear resistant filler flocs with a defined and controllable size distribution. In addition, a neutralizing coagulant can be added to the dispersion to partially or completely neutralize the charge of the filler before the microparticle and/or the first flocculating agent is added.
