The Pneumatic Sheet Press is a standard specimen preparation device specifically designed for pulp and paper laboratories, fully compliant with the QB/T 3703-1999 standard (Preparation of laboratory sheets + conventional sheet former method). This equipment adopts a pneumatic control system with an adjustable working pressure range of 0-0.9 MPa, a standard pressing pressure of 0.414 MPa, a cylinder diameter of 63 mm, and a nominal pressing force of 45-80 Kg. The pressing platen accommodates specimens up to 310×310×200 mm. By applying controlled pneumatic pressure, it rapidly removes water from wet handsheets, significantly increasing their density, smoothness, and physical strength. The unit features a compact and lightweight structure with overall dimensions of 570×400×900 mm and comes complete with an air compressor for ready-to-use operation. It is an indispensable step in the standard handsheet preparation workflow, delivering properly pressed specimens for subsequent physical property testing.
