Polypropylene diaphragm filter plate

Why is Polypropylene Diaphragm Filter Plate resistant to high temperatures?

In today's ever-changing filtering technology, Jiangsu Sudong Chemical Machinery Co., Ltd. is a leading domestic manufacturer and supplier of filtering equipment. It always stands at the forefront of industry innovation and is committed to providing efficient and reliable filtering solutions to customers around the world. One of our products, Polypropylene Diaphragm Filter Plate, stands out among many filtering equipment due to its high temperature resistance and is a trusted choice in many industrial fields. The following will explore the secret of Sudong polypropylene diaphragm filter plate's high temperature resistance.

1. Jiangsu Sudong Chemical Machinery Co., Ltd. Polypropylene diaphragm filter plate can maintain stable performance in high temperature environments thanks to its high-quality materials. Polypropylene is a semi-crystalline thermoplastic that has good heat resistance, chemical corrosion resistance and good mechanical properties. In the products of Jiangsu Sudong Chemical Machinery Co., Ltd., we carefully select high-purity, high-performance polypropylene raw materials to ensure the excellence of the basic material of the filter plate. However, pure polypropylene materials still face challenges under extreme high temperature conditions. To this end, Jiangsu Sudong Chemical Machinery Co., Ltd. introduced high-quality TPE as a modified material for the diaphragm. TPE, with its excellent elasticity, temperature resistance (it can maintain performance at temperatures from -40°C to 120°C or even higher) and chemical corrosion resistance, perfectly blends with polypropylene, improving the elasticity and resilience of the diaphragm, and greatly enhancing its stability and durability at high temperatures. The application of this composite material is an important cornerstone of the high temperature resistance of Sudong polypropylene diaphragm filter plate.

2. In addition to the selection of materials, the structural design of Jiangsu Sudong Chemical Machinery Co., Ltd. polypropylene diaphragm filter plate is also unique. Reasonable structural design can further improve the overall performance of the filter plate, including high temperature resistance. During the research and development process, we continuously optimized the core structure and flow channel design of the filter plate. Jiangsu Sudong Chemical Machinery Co., Ltd. polypropylene diaphragm filter plate adopts an integrated structure formed by high-temperature hot pressing of double diaphragms and core plates. This design ensures the close combination between the diaphragm and the core plate, and also forms a unique extrusion chamber (i.e., the hollow part). When the extrusion medium (such as water or compressed air) is introduced into this chamber, the diaphragm will expand and squeeze the filter cake in the filter chamber, achieving secondary extrusion and dehydration of the filter cake. In this process, the pressure and temperature of the diaphragm reached a high level, and it is precisely because of its unique material and structural design that the Sudong diaphragm filter plate can still maintain stable performance and high filtration efficiency at high temperatures.

3. High-quality products are inseparable from exquisite craftsmanship and strict quality control. At Jiangsu Sudong Chemical Machinery Co., Ltd., from the storage of raw materials to the delivery of finished products, every link is strictly checked and tested. We use advanced production equipment and technical means to ensure that the polypropylene diaphragm filter plate maintains stable quality and performance during the production process.
Especially in the high-temperature molding process, we strictly control key parameters such as heating temperature, pressure and time to ensure that the hot pressing bonding between the diaphragm and the core plate is firm and uniform. At the same time, we also conduct multiple performance tests on the finished products, including high temperature resistance test, pressure resistance test, corrosion resistance test, etc., to ensure that each filter plate can meet or even exceed customer expectations.

4. Jiangsu Sudong Chemical Machinery Co., Ltd. polypropylene membrane filter plates have been widely used in many industrial fields due to their excellent high temperature resistance. Whether it is oil filtration in the petrochemical industry, liquid medicine refining in the pharmaceutical industry, sewage treatment in the environmental protection field, liquid clarification in the food industry, etc., Sudong membrane filter plates can play their unique advantages and help customers achieve efficient and stable filtration operations. In the high-temperature oil refining process, Jiangsu Sudong Chemical Machinery Co., Ltd. membrane filter plates can effectively meet the filtration needs of high-temperature oil products and ensure oil quality and production efficiency; in the pharmaceutical field, its good chemical corrosion resistance and high temperature stability ensure the purity and safety of drugs. These successful cases have verified the technical strength and market competitiveness of Jiangsu Sudong Chemical Machinery Co., Ltd. polypropylene membrane filter plates, and have also won us the trust and support of more customers.
