Throughout the years, many fine chemical companies, including those that produce silicone products, have encountered difficulties in the production of powdered raw materials, which has become a bottleneck in their manufacturing processes and an issue that needs to be addressed urgently. The main problems include the following: 1. Environmental protection requirements – In the production process, manual handling is often required for powdered raw materials, especially those with low density or that are ultra-fine; it is difficult to effectively control dust in such environments, leading to poor working conditions and safety concerns. 2. Occupational health and safety requirements are becoming more stringent; it is essential for enterprises to protect the physical and mental health of their employees. 3. The demographic dividend is weakening; in the past, as long as there were people available, corporate production could proceed normally. Currently, there are significant challenges in recruiting and retaining employees. The working conditions are harsh, and the jobs are demanding, dirty, and physically exhausting – factors that are difficult for people born in the 1980s and 1990s to accept. Difficulty in recruiting staff has thus become a major problem for businesses today. Therefore, it is very important and urgent to introduce powder automation system engineering into enterprises. From a professional perspective, powder engineering has always been a weak point for specialized design firms. This requires not only a solid theoretical foundation in the technologies related to powder engineering, but also a thorough understanding of the properties of various powder materials involved. In particular, there is a need for accurate analytical data regarding flammable powder materials, as well as extensive experience in powder engineering ； This topic is quite long; it would take too much time to describe it here. Looking back at the powder automation projects in the silicone industry, over the past few years we have carried out projects at various silicone manufacturers across the country, successfully completing the owners’ tasks from project planning and design to overall project management. The clients have silicone enterprises in Zhejiang, Jiangsu (Nanjing), Anhui, Hubei, Shandong, Inner Mongolia, and Xinjiang; I won’t mention the specific companies here. The actual technical principles behind powder automation engineering are not complex; what’s important is automatic conveying, automatic batching, and automatic feeding. The entire process takes place in a sealed environment, and dust is only generated when the packaging is opened for feeding. However, with a well-designed and properly configured dust removal system, and by maintaining a basic level of cleanliness in the workshop, this issue can be fully addressed. The main powder raw materials used in silicone production are silica gel (vapor-phase silica and precipitated silica). The density of vapor-phase silica is 0.02 g/cm^3, and it is quite difficult to control dust during feeding and transportation. At present, we use a combination of pneumatic conveying and powder pumps; for long-distance transportation, silo pumps are employed. For example, for deliveries over 1 kilometre or 2 kilometres to regions such as Inner Mongolia, Xinjiang, and Shandong, silo pumps are used, while powder pumps are used for transportation within the workshop. Together with metering silos, this setup fully meets the requirements of continuous production processes. There are many technical aspects involved here: the calculation of the specifications for silos and dust collectors, the selection of dust collectors, the design of material suction guns, the volume and pressure specifications for silo pumps, as well as the selection of powder pumps – all of these require precise calculations. Overall, the design of the engineering solution is crucial for a project; it is necessary to engage in repeated discussions based on the user’s production needs and process conditions in order to develop a reasonable solution. Once this is confirmed, further detailed design work can be carried out. Over the past five years, through practical experience in silicone-related projects, valuable experience has been accumulated, and new technologies have been provided to users, which is certainly gratifying. Today, I would like to give a brief introduction to the application of powder engineering in silicone manufacturing enterprises; those who wish to discuss this further can do so in person.
