Interface refers to the thickness of the transition zone about a few molecules of the two-phase contact, such as one for the gas phase, which is usually referred to as the interface surface. At the interface of solid and liquid phases in contact, or on two different liquids in contact with the interface, the molecular basis of the two substances, each with respect to the same number of molecules within the truth of the summed value of excess free energy, it called interfacial tension. Gas-liquid interfacial tension, the surface tension of the liquid is also called, is the interfacial tension between the liquid and the air. Steel heating is heating means almost all plastic mold design must be used, can be designed for a one-way connection, bi-wiring and other forms, can be seam pipe, seamless pipe, stainless steel pipe and other material on, and there is heat loss small, high thermal efficiency, simple cable, designed according to the need for 220V or 380V, flexible wiring formula. However, due to limitations of its materials and processing technology of contact angle measurement wholesale, mold design should pay attention to the body that it features. 2 drilling heating pipe installation from the perspective of understanding of heat transfer, heat pipe installation To fit the mold surface as possible, in order to facilitate heat transfer heat pipe to the mold as soon as possible. In fact heating tube and the mold is not much contact area, the nature of the radiation heat transfer is the contact angle meter, conductivity is secondary. Thus most of the heating tube surface for mounting the mold are coated with a coating to enhance infrared radiation, but also limits the use of the design power (10 watts / cm) approach to increase the life of the heating tube. Therefore, in the processing of the contact angle measurement instrument manufacturers heating holes, especially the long heating hole machining is not necessary to design with the gap is too small, efficient design approach is possible with the heating pipe at both ends of the hole tight fit, you can stuffer, plugging or other measures designed to blank. This approach can effectively reduce the heat dissipation area and the radiant heat pipe losses.
