The invention discloses a fine loading control device of a static pressure bubble test. The fine loading control device comprises a base, wherein a protection case is arranged at the upper end of thebase and provided with a first cavity and a second cavity via a partition; a first transparent container with scales and a second transparent container with scales are arranged in the first cavity andthe second cavity respectively; the bottom of the first transparent container is communicated with the bottom of the second transparent container via a pipeline located in the base; T-shaped bolts penetrate through the middles of L-shaped support plates; one end of each T-shaped bolt is connected with a hold-down plate; a base layer covered by a sample to be detected is sealed by the left hold-down plate and the right hold-down plate at an upper port of the first transparent container. The device is very simple in structure and easy to operate; the lower part of the base layer of the sample to be detected is compressed on a side wall of the upper port of the first transparent container by the left hold-down plate and the right hold-down plate via locking of the T-shaped bolts; time wasteand inaccurate testing data due to falling-off of a coating film in an experimental process are effectively avoided.
Description
technical field [0001] The invention belongs to the technical field of static pressure bubbling test, in particular to a fine loading control device for static pressure bubbling test, and also relates to a method for using the fine loading control device for static pressure bubbling test. Background technique [0002] Thin-film technology has been widely used in many fields, such as protective coatings, decorative coatings, and thin-film devices in the microelectronics industry and optoelectronics industry. For protective coatings or decorative coatings, ie coating film-substrate structures, the reliability, stability, lifetime, etc. of film-substrate systems require a better understanding of the mechanical behavior of thin layer structures. [0003] Through the small holes in the base layer of the membrane-based system, the coating film adhered to the base layer is loaded. Since the hydrostatic pressure can only be applied according to a certain value, such as 1 Newton per ...
