As environmental pollution becomes more and more serious, the country has put forward more stringent standards for flue gas emissions. Faced with this development pattern, line pipe companies must strengthen the application of flue gas dust removal technology and make a good choice of dust removal filter bags based on actual production conditions, in which PTFE coating processing is indispensable.
The coating process can be divided into pre-coating film technology and instant coating technology according to the different raw materials and equipment used. The two processes are mainly: solvent-free hot-melt adhesive pre-coating dry composite process and emulsion adhesive wet-coat composite process. Solvent-free hot-melt adhesive pre-coated film dry lamination has condensed and simplified the lamination production process into a single hot pressing, and is currently widely used in China. The core technology of the emulsion adhesive wet-ready composite process is mainly reflected in three aspects: coating, cold pressing, and drying.
Undertake various filter material PTFE coating processing services. Our company will perform coating processing according to the coating substrate provided by the customer or the coating substrate specified by the customer. The key to its technology is the optimized combination of speed ratio, pressure ratio, operating temperature and other parameters. Our company can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different needs of users.
The ptfe biaxially stretched film produced by ptfe coating processing has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can obtain high dust removal efficiency. For some diameters of 0.1 For ultra-fine particles ranging from um to 0.3um, the filtration level can reach H13-U16. In addition, the biaxially stretched film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the company’s production process, and it fully complies with current environmental protection standards.
