Product Description
Buick smoothness tester is a high-precision testing equipment designed and developed according to the working principle of the internationally used Buick smoothness tester for testing the surface smoothness performance of paper and cardboard. Smoothness is an important indicator to measure the flatness and finish of the paper surface; It determines the smoothness of a material by passing a certain amount of air through the gap between the surface of the specimen and the glass anvil of the instrument under specific pressure conditions, and measuring the time it takes for air to pass through.How it works:
Smoothness is an index to evaluate the unevenness of the paper surface, which indicates the flatness and smoothness of the paper surface. Paper or cardboard tray material is placed on a glass plate, a specific pressure is applied to create a semi-vacuum, which draws in air and passes it through the contact surface, measuring the time it takes for the vacuum level to change within a specified range. Under a specific state and a certain vacuum degree, the time required for a certain volume of air to pass through the gap between the sample surface and the glass surface under a certain pressure is the smoothness of the paper, which is often expressed in seconds (s). The smoother the surface of the paper, the longer the air will flow in; Conversely, the smoothness is low, and the time for air to flow in is shorter.
