Suitable adjustment of the measurement of the aspect ratio can be measured for different types of fibers, the bending properties such as high performance fibers, metal fibers, spider protein fiber, cashmere, fibers, and various commonly taking objective and quantitative evaluation of the modified fiber. The method and device solves the short fibers (such as cashmere, cotton fibers) can not be measured bending performance problems, but also for a variety of filament fibers. To measure the bending properties of the yarn, by changing the film and the fabric, or on different platforms with a pore diameter of fine grooves. Leaflets photography function. Successive punctual photography functions, arbitrary adjustable time punctuality. Tangent method measurement methods appear directly contact angle values, accuracy 0.1 °. Supreme Court chord measurement method, the contact angle values ??appear precision 0.1 °. Ellipse fitting method to measure the contact angle values ??show the accuracy of 0.1 °. Protractor method measuring method, the contact angle values ??appear precision 0.1 °. Measurement scale: 0 ~ 180 ° maximum frame rate: 25 frames / sec arbitrary rotation and moving graphics, graphics conclude automated accounting viewpoint and can immediately apparent. A complete picture of the overall test results and save function. JY-PHa primary contact angle measurement equipment: contact angle host, Lenovo's commercial aircraft a majority of solid materials are made from a variety of different particle shapes constructed, therefore, fine particulate material shape and size of the material structure and performance has a significant impact. Especially for nanomaterials powder contact angle measurement, the particle size and shape on the properties of the material plays a decisive role. Therefore, nanomaterials particle size, shape characterization, and control is of great significance. General solid material particle size particle size can be used to describe the concept. However, due to the complexity of the shape of the particles is generally difficult to directly use a scale to describe a particle size of the optical contact angle measurement, and therefore, the particle size is widely used in the description of the process of the concept of equivalent particle size. For the different principles of particle size analysis instruments, measuring principle is based on the different characteristics of the particle is not the same, only the equivalent contrast, a direct comparison can not be laterally. Such as sedimentation particle size analyzer is based on an equivalent particle settling velocity contrast, the measured vertical diameter of settling velocity equivalent diameter, which uses the same diameter as measured particle settling velocity of homogeneous spherical particles to represent the actual particle size. Diameter of the laser particle size analyzer is the use of a laser diffraction and scattering characteristics as an equivalent contrast, the measured particle size of the equivalent diameter of the equivalent scattering, i.e., actual measured particles having the same scattering effect of the spherical particles to represent the actual size of the particles. When the measured particle is spherical, its particle diameter is equivalent to its actual diameter. Molding process is one of the most common plastic material, the oldest molding method, and is a process for research material properties of the most commonly used. It has a molding apparatus is simple, small investment in equipment, simple mold structure and other characteristics contact angle measurement, in mechanization and automation of production today's highly developed video contact angle measurement, still one of the one of the most popular means of production. However, compression molding die design can refer to the literature in addition to textbooks, monographs written several predecessors, mold design legend, few people die design summary of key skills.
