(www.dgshengding.com) is specialized in the "contact angle measurement, tensile tester, drop angle detector, tables, interface instrument" of the enterprise, the company adhering to the "honesty, hard service" philosophy, to provide you with the highest quality products and services. Welcome to inquire! Contact: Lee. Most of the solid material are constructed from a variety of different shapes of the particles from the contact angle measurement, and therefore, the fine particulate material shape and size has an important impact on the structure and properties of the material. Especially for nanomaterials, 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, 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 powder contact angle measurement, 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, in mechanization and automation of production is highly developed today, 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. Heating a mold clamping of the mold structure, the insulation is closely related with the cooling system, while providing a certain convenience features for the replacement of the mold, handling. Most of the designers for the convenience of maps, just simply make a few mounting holes for fixing the mold. Most cases are not individually designed heating device die contact angle measuring instrument price, but mounted on the upper and lower platen press heated plate to simplify SME mold processing. Mold structure on the left constitutes the main structure of the module cavity. Then the mold approaches the fixed mold may be an injection molding mold ?? platen is fixed to the upper and lower templates. On the heating plate fixed platen mold design space can be good. This design not only can be used in the mobile die, the die can also be used with a simple mechanism of entry. Only need to design the heating plate before considering the ram position does not conflict with the heating pipe can be. You can also utilize a plurality of mold mold mold versatility transformation to simplify the mold manufacturing cost. If the mold is higher, simply can not meet the heating plate is heated uniformly heating needs, then you need to install an auxiliary heating system in the mold, you can mountain heating film, heating pipes and iron core composition. For a simple structure, small size of the mold, using a heating plate heating will cause a large amount of heat loss through the high temperature contact angle measurement, in the mold body design simple heating system can meet the requirements. Note that between the mold and press the fixing plate to add insulation material (usually to the use of asbestos cardboard) to insulation, also need to pay attention to the position neatly routed and galvanic bore power lines. This design); Due to the heat capacity is smaller, particularly for applications that require repeated heating and cooling or rapid heating and cooling of the small mold
