The present invention provides a dispersant and foaming agent combination that is useful in the production of gypsum wallboard and other aqueous cementitious products, a method of forming a gypsum wallboard and a gypsum wallboard. The dispersant in the combination according to the invention is a naphthalene sulfonate-aldehyde condensate alkali salt polymer having a weight average molecular weight of from about 17,000 to about 47,000. The alkali is preferably an alkali metal and/or an alkaline earth metal. The aldehyde is preferably formaldehyde. The foaming agent used in the combination according to the invention is a soap, preferably an alkali salt of an alkyl ether sulfate and/or an alkyl sulfate. The combination of a high molecular weight dispersant and a foaming agent produces a gypsum wallboard core effect that more efficiently entrains air (i.e., creates void space), thereby lowering overall board weight without detrimentally affecting strength. A gypsum wallboard formed using the dispersant and foaming agent combination according to the invention exhibits a higher nail pull value than gypsum wallboard formed using a conventional dispersant and a foaming agent at the same solids loading ratio.

To carry out drying of printing ink with the use of Nano sized high-temperature dryness steam. Nano sized high-temperature dryness steam being clustered on Nano oder is generated and jetted to the print side of printed material so that the Nano sized high-temperature dryness steam imparts intramolecular vibrational energy to ink of the print side. Consequently, the Nano sized high-temperature dryness steam being clustered on Nano oder not only passes through fiber pores in the printed material but also collides with the ink of the print side. The Nano sized high-temperature dryness steam having collided with the ink of the print side imparts thermally excited energy as intramolecular vibrational energy to the ink containing polar molecules. The ink is dried by the intramolecular energy.
