1. Electroplating, oxidation, electrophoresis industry
The chiller is oxidized in the electroplating industry and the electrophoresis industry. The chiller helps to stabilize the metal and non-metal ions, so that the metal ions can be quickly attached to the electroplated parts, oxidized parts, and electrophoretic parts, which not only increases the density and smoothness, but also reduces the number of plating During production, the electroplating solution generates heat indefinitely during the electroplating reaction, thereby gradually increasing the temperature of the electroplating solution. When the temperature of the electroplating solution exceeds the requirements of the process, the firmness and uniformity of the appearance of the electroplated finished product produced. , Flatness and appearance finish have a greater impact. However, the choice of freezing the electronic components provided by the chiller requires the components to be connected or cooled at a specific temperature during the production process, and the functional parameters of the electronic components are controlled in a preset state. Water is used to cool and connect the constant temperature of the plating solution, which will greatly improve the plating production process and production efficiency.
2. Reactor cooling
In food plants, pharmaceutical plants, and chemical plants, in the process of industrial production in which the reaction kettle participates, the raw materials in the kettle need to be rapidly cooled down. In order to achieve this purpose, we hope to directly cool down the reactor, so as to indirectly reduce the temperature of the material in the reactor. Therefore, we need to use appropriate refrigeration equipment to reduce the temperature of the reactor.
3. Ink and powder coating industry
During the grinding process of ink or coating, the molecular structure of the material will be changed to produce high temperature, which will affect the quality of the raw material. This will cause a reduction in production efficiency and severe wear on the grinding machine. At this time, we need to perform constant temperature control on the cold water provided by the grinding machine to protect the quality of equipment and raw materials, and also improve production efficiency.
When the grinding raw material becomes powder, the powder temperature will agglomerate if it is too high. Affects production efficiency and powder quality. At this time, we need to install low-temperature cold air into the grinding chamber to rapidly cool the materials, and the materials are not agglomerated.
4. Injection, blister, extrusion industry
Injection: Injection molds basically require a cooling system, because injection molds are injected into the mold cavity by heating the molten plastic particles in the injection machine to a couple of Baidu. Imagine that hot plastic is injected into the mold cavity. If the cooling system is not used, the product with a cycle of 30 seconds will naturally take a long time to cool. It may be 5 minutes, 10 minutes, or 20 minutes. One mold, so the production cost is too high.
Blister: In order to improve production efficiency, vacuum blister molding products often need to be cooled before being ejected from the mold. Ideally, the inner and outer surfaces of the part in contact with the mold are cooled, and it is best to use a built-in cooling coil mold. For non-metal molds, such as wood, gypsum, glass fiber reinforced plastic, epoxy resin and other molds, because they cannot be water cooled, they can be replaced with air cooling, and water mist can be added to cool the outer surface of the vacuum blister molding.
Extrusion: Cooling of extruded products is an important measure to ensure product geometry and internal structure. After extruding the plastic extrusion cladding, it should be cooled immediately, otherwise it will be deformed by gravity. For non-crystalline materials such as polyvinyl chloride, the problem of crystallization can be ignored. Plastic products can be quenched by direct cooling with water to allow them to cool through in the cooling water tank without deformation. The cooling of crystalline polymers such as polyethylene and polypropylene should take into account the crystallization problem. If the rapid cooling method is used, it will adversely affect the structure of plastic products and generate internal stress, which will cause cracks in the product in the future. One of the reasons must be paid attention to in the extrusion process; the extrusion cladding of crystalline plastics such as polyethylene and polypropylene should be carried out by gradually cooling the temperature of warm water. Generally, it depends on the auxiliary equipment of the equipment. The cooling water tank should be divided The sections are divided into sections. The water temperature can start from the temperature of 75 ℃ ～ 85 ℃ that the plastic cladding enters the first section of the water tank, and the water temperature is lowered step by step to room temperature. The smaller the temperature difference between the sections, the more reasonable.
