Suitable for epoxy resin casting high-end small products or small batches of epoxy casting!
The small static mixing vacuum casting equipment is also a full vacuum static casting principle. The core technology is a two-component epoxy resin mixture, which is uniformly mixed by a static mixer. In principle, the mixing time of the two-component mixture is shorter. The fresher the material obtained. Compared with the traditional dynamic mixing method, the mixed materials are more fresh and suitable for the pouring of high-grade products. The principle of static mixing pouring equipment is to push the materials of equal pressure through the metering pump to realize the “material division-position movement-reconvergence” turbulence. In addition to the above three conditions, the fluid will also generate severe eddy currents in the cross-section direction. Strong shear forces act on the fluid, allowing the fluid to further split and mix and eventually mix to form the desired emulsion. It is called a "static" mixer because there are no moving parts in the static mixer. Through the cross-over method, the mixing of more than 100 million times is realized instantaneously, the mixing time is shortened to the greatest extent, and the chemical reaction time of the two-component materials is basically all delivered to the mold.
The small static mixing and pouring equipment mainly consists of a set of resin feeding system, a set of curing agent feeding system, a set of resin mixing degassing measuring tank system, a set of curing agent mixing degassing measuring tank system, and high precision. Two sets of silicon carbide pump system, one set of static mixer system, one set of vacuum casting tank system, one set of vacuum system, three sets of heating system, one set of cooling water system, one set of compressed air system, one set of control system, equipment A set of steel frames.
The small static mixing casting equipment is suitable for high-grade product requirements. The final mixing tank is replaced by the static mixer of the static equipment. The same pressure, the same or different proportions of materials pushed by the metering pump are mixed, the mixing time is short, and the mixing is short. The material is fresh, the flow performance is superior, and the wettability to the coil is improved. In short, the gel state of the first kilogram of the mixture and the last kilogram of the mixture in the dynamic mixing tank is different, and the material that enters the mold later than the material in the front, viscosity and infiltration The sex is much lower, that is, the quality is uncontrollable; and the gel state of the static mixture hitting the mold every stroke is exactly the same, regardless of time.
The casting production of dry transformers, dry transformers, dry reactors, basin insulators, insulators, etc. requires an epoxy vacuum casting equipment whose main function is to cast epoxy resin into the mold. The steps are also an important part of dry product production. In the specific implementation, the wound coil is first pre-baked in an oven, and the temperature reaches the temperature required for the active flow of the resin, and then transferred to the casting tank to vacuum-cast the epoxy coil in the mold to be ring-shaped. After the oxygen resin overflows the mold and the coil, it is transferred to the curing furnace, and after being completely solidified in the curing furnace, the mold is removed and the mold is removed to obtain a complete dry coil.
