    摘要: The following method is used to measure the adhesion of a polymer binder to a heated metal surface:
    A metal plate is attached to a heated (350 °F; 177 °C) platform and allowed to equilibrate to the temperature of the platform. A polymer emulsion binder is applied to a substrate, such as cotton fabric, and an end of the coated substrate is attached to a tensile measuring apparatus. The coated side of the coated substrate is pressed onto the heated metal plate; e.g., using a 3-Ib lab roller. After a length of time to cause drying and/or partial cure of the binder (approximately 30 seconds), the metal plate and the tensile measuring device are separated at a given uniform speed. The amount of force needed to remove the substrate from the metal plate is recorded.

    摘要: Method and apparatus for measuring, monitoring and/or providing an indication of material 'damage' in board products, particularly Machine Direction (MD) Shear. In this regard, the present document discloses applying a predetermined force to a board product such that the board product is not deflected beyond its elastic region. The apparatus used for applying the force is preferably of a size or structure suitable for physically limiting the amount of deflection of the board product. By maintaining the board product within its elastic region as such, the occurrence of permanent damage to the board product is reduced. Hence, the disclosed method and apparatus are able to provide a non-destructive indication of MD Shear on the paperboard product being tested, and are thus suitable for use in on-line testing/monitoring of paperboard production.
