Buried discharge heat pipe, preferably the inner tube of the same media magnesium oxide powder filling optical contact angle meter, to reduce the heat load on the heating tube surface, this method can reduce the surface oxidation of the tube, effectively extending the life of the tube . Able to do so, the mounting holes are the best heating pipes poured into magnesium oxide powder. Insulation measures to strengthen the mold can reduce heat loss of the mold, the mold will reach a predetermined temperature in a short production time and reduce energy waste. Each engineering and technical personnel on this issue has a unique solution, I only talk about my experience. Many die insulation measures the contact angle, the available asbestos cloth or glass cloth wrapped aluminum hydroxide cotton insulation warm. Now on the market there is a thermal insulation coating is the ideal insulation material for the mold, it is the Chinese and long fiber pulp, and a mixture of foam insulation, moderate viscosity, easy to apply. This material is often used as insulation material in chemical, heating pipes, containing slightly alkaline (corrosive mold). After use at 150 ℃ conditions not found charred, melted, the negative impact of smell. At the same time the material is very light, strong plasticity, easy to form a more beautiful mold surface water cooling is used to cool the way the majority of the mold surface and interface contact angle tester, but also has its drawbacks; require pipeline seal better, way down pipes must be smooth, big waste of water. When the cooling temperature exceeds 100 ℃, easy to produce steam explosion. The advantage is a large heat capacity, enabling rapid cooling. Air cooling is an ideal method for cooling and water cooling the contrary, it does not require tight pipe sealing surface energy WORK contact angle, there is no waste of resources, can be higher than the cooling temperature of the mold 100 ℃, gas can flow through to determine the rate of cooling, and the source of simple and convenient, there is a certain scale production plant can be made more convenient gas source.
