摘要:
It is an object of the present invention to provide a method for simply mixing two or more types of liquids in a porous carrier. The present invention provides a method for mixing two or more types of liquids in a porous carrier, which comprises: laminating a first porous carrier consisting of an upstream portion and a down stream portion that are integrated with each other on a second porous carrier consisting of an upstream portion and a downstream portion that are integrated with each other, such that the upstream portion of the first porous carrier and the upstream portion of the second porous carrier form a bifurcated portion; adding a first liquid to the upstream portion of the first porous carrier; adding a second liquid to the upstream portion of the second porous carrier; and giving external force in a vertical direction towards the first and second porous carriers at a position wherein the first porous carrier is laminated on the second porous carrier on the side downstream of the bifurcation point of the bifurcated portion, so as to mix the first liquid with the second liquid in the first and second porous carriers.

A liquid ejection apparatus (10, 10', 10") includes: a gas chamber (60) surrounding a piezoelectric element (56) in an inkjet head (16K, 16C, 16M, 16Y, 16K', 16C', 16M', 16Y', 16K", 16C", 16M", 16Y"); and a dry gas supply device (70, 70', 70") configured to start supply of dry gas to the gas chamber (60) before supply of electric power to the inkjet head (16K, 16C, 16M, 16Y, 16K', 16C', 16M', 16Y', 16K", 16C", 16M", 16Y") is started, to continue the supply of the dry gas while the supply of the electric power to the inkjet head (16K, 16C, 16M, 16Y, 16K', 16C', 16M', 16Y', 16K", 16C", 16M", 16Y") is continued, and to halt the supply of the dry gas after the supply of the electric power to the inkjet head (16K, 16C, 16M, 16Y, 16K', 16C', 16M', 16Y', 16K", 16C", 16M", 16Y") is halted. While the dry gas supply device (70, 70', 70") halts the supply of the dry gas to the gas chamber (60), a dry gas supply flow channel opening and closing device (80) is closed to disconnect the dry gas supply device (70, 70', 70") and the gas chamber (60), and a gas return flow channel opening and closing device (84) is closed to disconnect the gas chamber (60) and the external air.
