Throughout the world, the use of intermediate bulk containers to transport and store liquid chemicals has become more common. Similarly, in the production of polyurethanes, the use of a 1000 kg container drum has significant advantages. According to Hennecke, the module The medium-sized bulk container station simplifies the loading and unloading of containers, ensures the stable and reliable process flow, and has higher cost-effectiveness due to the standardization of production and mass production.
Hennecke produces polyurethanes from modular medium-sized bulk container stations
Polyols and polyisocyanates are the most important raw materials for the production of polyurethanes. In the process of producing raw materials, excipients that can be added to polyols to facilitate processing, mainly include blowing agents, activators, emulsifiers and foam stabilizers. These excipients can Precipitate at the bottom of the container very quickly. In order to maintain consistent and repeatable production results, the polyol and excipient must be thoroughly mixed and homogenized before the material is filled into the metering machine. On the other hand, the polyisocyanate can be used without additional modulation. .
Chemical raw materials are also hazardous materials with potential risks. Clean and safe processing of raw materials is not only important for the health of employees, but also very important for the protection of the environment. The quality of raw materials is crucial for the production of high-quality polyurethane products, and therefore the quality of the raw materials being processed. It may not be affected during the transfer process.
Polyurethane processing equipment has high requirements for raw materials. For polyurethane processing equipment, tank equipment is the best solution for regulating chemical raw materials and filling polyurethane measuring machines. Many small and medium-sized raw material manufacturers have impractical storage equipment. 200 kg barrels will be used to replenish raw materials. Compared to medium-sized bulk containers with a capacity of 1,000 kg, polyurethane processing units must replace empty buckets more frequently with full barrels. Use of medium-sized bulk containers can prevent contamination by loading or replacing barrels. Faults and sources of error during processing, and can increase production efficiency.
Hennecke stated that it has developed a new medium-sized bulk container station for the exclusive use of drums. In addition to a consistent modular structure, it also has a unique selling point that is not available in similar products. Therefore, the system is to apply medium-sized bulk containers. The best solution for polyurethane production. For the user, its advantages are manifested at the time of loading: With a flexible structure, the user can assemble it by means of a stacker or crane. In bulk container stations, each Raw material components are marked with colored labels. Using rails and brakes, the medium-sized bulk container can be installed in the ground-mounted base frame. After the hose is properly configured and connected, the stirrer is released. When the button is pressed, the stirrer automatically enters. container.
After the stirrer has fully entered the container, the container is automatically sealed.
The controller can store a variety of processes for the processing of polyols. Therefore, it can be programmed. For example, at the beginning of a defined period of time, the stirrer passes in rapid succession to homogenize the material. During this time it cannot be removed. Raw material. After this, the raw material can be removed, the stirrer goes into protection mode, and the speed and interval switch slow. This ensures that the raw material is always filled into the meter under the same conditions. This ensures the high reliability of the process. During the raw material process, there is a continuous charge height detection. Therefore, the Floatjet and the pump can be automatically controlled and the need to replace the container can be displayed. The support expansion base can be used as needed to place the collection basin and the drying cylinder to dry the inflow Air. By separating the intermediate bulk container station into multiple individual modules, it can accommodate polyols and isocyanate intermediate bulk containers, which can be expanded as needed. The intermediate bulk container station can also be integrated into existing polyurethane processing units.
