Recently, laboratory personnel from Wuxi Shuangrui Machinery Co., Ltd. and experts from a certain new material company jointly conducted an experiment on the filtration and drying of PPE resin materials at the Wuxi Shuangrui Experimental Base. The experiment aims to investigate whether PPE resin material can form a filter cake during the filtration and drying process, and whether the pressure is stable under vacuum.
Experimental Procedure
This experiment uses a 100L pilot cylinder cone filtration, washing, and drying three in one equipment. The experimental steps are as follows:
Put the material into the equipment, add solvent for stirring and filtering.
After sufficient filtration and stirring, helium gas is injected and pressurized to discharge the filtrate.
After the filtration is completed, remove the cone filtration part and observe the condition of the material filter cake.
Experimenters release PPE resin
experimental results
The experimental results showed that the filtrate discharged by stirring and filtering was clear without any discharge, and the material in the lower cone did not form a filter cake during the process of pressurized discharge of the filtrate. This indicates that Wuxi Shuangrui's three in one equipment can efficiently stir and filter materials, providing convenience for the subsequent drying process. In addition, the time required and final effect of drying materials in separate equipment have also been improved.
Cone type filtration, washing, drying, three in one material, pressurized and stirred to produce liquid
Based on the experimental results, the Wuxi Shuangrui technical team conducted in-depth discussions with experts in new materials. Due to PPE resin (polyphenylene ether) being an amorphous resin, its glass transition temperature (Tg) is approximately 210 ℃. The main molecular chain is composed of benzene rings connected by ether bonds, which endows the resin with a high degree of hydrolysis resistance. PPE resin has a low water absorption rate and a density of only 1.06, which is considered a relatively low level among general engineering plastics. During the process of pressurized stirring and filtration, due to the loose material, it is difficult to form a thick filter cake. However, after putting the materials into independent vacuum drying equipment, the drying time required was significantly reduced compared to the company's past data. Of particular note is that the filtrate obtained during the pressure filtration process is clear and leak free, earning high praise from the company's experts. At the subsequent equipment technology seminar, Wuxi Shuangrui's technical and sales personnel won high praise from customers for their unique insights into PPE resin technology.
Core equipment - cone filter, washing and drying three in one
A new type of filtering washing and drying machine with a conical structure is equipped with heating jackets on the cylindrical body and lower cone, which can heat or cool the material. Inside the multifunctional machine, a hollow shaft and a hollow spiral stirring device with variable angle and pitch are installed to stir and lift the material, and push it out during discharge. A conical filtering device with a relatively complex structure is installed inside the lower cone, and there is a specially designed quick discharge device with almost no dead corners or a pneumatic discharge ball valve with almost no dead corners at the bottom of the equipment.
In the reaction stage, the reaction material is added from the top, and the stirring structure can achieve very uniform stirring of the material inside the machine. The material is heated or cooled simultaneously through the cylinder jacket, cone jacket, hollow shaft, and hollow spiral blade, allowing the material to fully react inside the machine. In the filtration stage, this machine can filter and dry the material through pressure or vacuum filtration inside the machine, and add washing solution to automatically re slurry and wash the material multiple times inside the machine. After meeting the washing requirements, it can be compressed and dried again. In the drying stage, the cylinder jacket, cone jacket, hollow shaft, and hollow screw simultaneously heat the material and vacuum it at the top to perform vacuum sealed low-temperature drying. After drying, the material is automatically sealed and discharged.
Equipment application prospects
Wuxi Shuangrui's cone type filtration, washing, and drying three in one equipment performs well in the filtration and drying process of PPE resin materials and has broad application prospects. This device is not only suitable for PPE resin materials, but can also be widely used in the filtration and drying process of other materials. For example, fine chemicals and pharmaceuticals: antibiotics, APIs, biotechnology, colorants, crystals, essence and spices, natural extracts, peptides, drug synthesis, vitamins; Chemicals: additives, catalysts, colorants, metal powders, minerals, pigments, polymers; Food: additives, animal extracts, coloring agents, spices and flavorings, natural extracts, vitamin supplements. With the continuous development of technology, Wuxi Shuangrui will continue to increase its research and development efforts, continuously launch more efficient and intelligent filtration and drying equipment, and make greater contributions to the development of various industries.
