    摘要: A small flow of a water with a high carbon dioxide content (normally a carbon-dioxide-saturated water) is produced using hollow-fiber membranes, and is uniformly mixed with a large flow of untreated water with constant proportions. Since the hollow-fiber membrane module has a reserve capacity for adding carbon dioxide to the water, the resistivity of the mixed water is maintained at a constant level by maintaining constant proportions of the small and large flows, even if the total flow rate fluctuates due to fluctuations in the rate of water used in a subsequent process. Accordingly, no automated control device is particularly necessary in order to maintain the resistivity at a constant level. Therefore, a compact and simple apparatus can be produced which can operate at a low cost.

    摘要: An apparatus for controlling the resistivity of ultra pure water, including a housing to house a gas permeable membrane, an inlet for untreated ultra pure water which communicates with an ultra pure water path, and an outlet for resistivity-controlled ultra pure water which communicates with the ultra pure water path. The gas permeable membrane divides the interior of the housing into the ultra pure water path and a mixed gas path. A mixed gas is selected from the group consisting of a mixed gas including carbon dioxide and a gas having a lower resistivity controlling ability than carbon dioxide and a mixed gas including ammonia and a gas having a lower resistivity controlling ability than ammonia. The gas permeable membrane is capable of supplying carbon dioxide or ammonia to the untreated ultra pure water at a concentration equal to or more than 90% of the equilibrium concentration.

    摘要: To provide a papermaking internal sizing agent capable of efficiently imparting sizing performance even in neutral papermaking which uses calcium carbonate as filler, and uses no aluminum sulfate or uses a small amount of aluminum sulfate, and also provide a paper or a paperboard obtained by using the papermaking internal sizing agent. The papermaking internal sizing agent comprises as an effective ingredient an amphoteric copolymer having hydrophobic groups and cationic groups, at least a part of the cationic groups being quaternized. Preferably, the amphoteric copolymer is obtained by polymerizing monomer ingredients that it essentially contain a hydrophobic monomer (A), a cationic monomer (B), and an anionic monomer (C) and that an anion equivalent of the monomer (C) is 0.1 to 90% of a cation equivalent of the monomer (B), in which a rate of quaternizing of the cationic groups is not less than 40% by mole. The paper or the paperboard contains the above papermaking internal sizing agent.

    摘要: To effectively impart sizing performance to paper, while reducing the amounts of an internal sizing agent and aluminum sulfate, the invention provides as a papermaking additive a mixture of a cationic copolymer having a hydrophobic group whose quarterization ratio is 40% by mole or more, or an amphoteric copolymer having a hydrophobic group which has the same quarterization ratio as above, and in which the ratio of the anion equivalent to the cation equivalent is 0.1 to 90%, and a filler (a pretreated filler). The pretreated filler is one in which suitable water repellency is imparted to the filler. Hence, by adding this to pulp slurry, followed by a wet papermaking, the pretreated filler is efficiently adsorbed onto pulp fibers having anionic property, so that effective sizing performance can be imparted to the paper by using a smaller amount thereof than the internal sizing agent, while reducing the amounts of the internal sizing agent and the aluminum sulfate.
