The present application discloses a sizing method for making paper. An alkenyl succinic anhydride (ASA) is added to a papermaking process. An aluminum salt is added in one or more process steps during the papermaking process. Preferably, the aluminum salt is an aluminum salt which can generate free aluminum ion in aqueous solution. The sizing method of the present application enhances the usage efficiency of a sizing agent and the aluminum salt, as well as provides paper having a high moisture content.

Sizing method for making paper and paper prepared thereof

The present invention provides a laundry processing apparatus (), which includes: a laundry processing drum (), used for holding laundry for processing; a driving system (), used for driving the laundry processing drum () to process the held laundry; and a power control system (), at least used for providing power of a grid for the driving system (), where the power control system () includes an electrical storage device (). Through the setting, when external grid power outage occur or the fluctuation of the voltage is excessively large, the power control system may switch a power storage device to supply power to the laundry processing apparatus, thereby eliminating the influence on the apparatus caused by unstable voltage of power transmitted by the grid or grid power outage, and avoiding the trouble brought to a user.
