Double membrane gas cabinet structure features and installation
Double membrane gas cabinet structure features and installation of double membrane gas cabinet graphic details, double membrane biogas cabinet - double membrane gas cabinet technical requirements, double membrane gas cabinet operation principle, double membrane gas cabinet characteristics and advantages introduced manufacturer Chen manager double membrane gas cabinet Introduction of double membrane gas cabinet membrane: The material selection of double membrane gas cabinet is very important, and the quality of the material determines the quality and life of the whole gas cabinet. Fluoride materials with strong tensile strength, anti-corrosion, anti-UV, and certain acid and alkali resistance are generally selected. Not all materials containing fluorine or fluorine coating are suitable. Special composite materials are required to ensure the applicable life. Generally, materials with good flexibility, strong tensile strength, compact composite, good air tightness and anti-corrosion are used. The double-membrane gas cabinet membranes are made of corrosion-resistant environmentally-friendly composite materials, mainly composed of high-strength tensile fibers, air-tight anti-corrosion coatings and surface coatings. They have anti-corrosion, anti-aging, anti-microbial and ultraviolet functions, and are fireproof. The level reaches the B standard. 1. The physical properties of the double-film gas cabinet membrane are the tensile strength, tear strength and elasticity of the material. The strength of polyester fiber is generally 44-71 cN/dtex, and it has good heat resistance, light fastness and wear resistance, and can be used at -70 to 170 °C. The film is arranged in a textile manner in the horizontal and vertical directions. The H6 series material can withstand a tensile strength of 7000N/5cm after molding, and its ideal flexibility and wide temperature range are ideal membrane materials. Base cloth selection. 2, the surface treatment of double membrane gas cabinet is mainly self-cleaning, anti-ultraviolet and natural aging, which mainly refers to the outer membrane. The outer membrane material needs to be specially self-cleaning and anti-aging on the surface, generally PVDF treatment. The better materials are treated with high concentration PVDF watch, which has good performances in anti-ultraviolet, self-cleaning and anti-aging. The theoretical life under natural conditions is more than 30 years, and the actual life can reach at least 15 years. Heavy rain can make the surface as clean as the wash, and the appearance is greatly improved. This kind of material can't be directly welded. When welding, it is necessary to remove the surface of the welded surface, which is more difficult to process. The H66 type membrane is treated with three times of PVDF. 3, double membrane gas cabinet resistance to gas corrosion mainly refers to the material and stability of the coating. According to different gas main bodies, the existing anti-sulfurization corrosion, acid and alkali resistance, anti-microbial or anti-organic dissolution. High-quality materials use additives with good corrosion resistance and weather resistance, and the actual use effect is superior. 4. The material and process of the gas-tight coating of the double-film gas cabinet determine the airtightness of the material. The quality of the material coating is relatively tight, and the coating process is more precise, which can effectively prevent gas leakage. Gas leaks can cause an explosion hazard, and the most immediate hazard is damage to the material itself. Corrosive gases penetrate into the material and are likely to cause premature corrosion of the base fabric or bonding layer of the material. 5. The bonding strength (peeling strength) of the double film gas cabinet is the bonding strength between the coating, the surface treatment and the base fabric. High-quality materials have high bonding strength, good welding quality and are not easy to open. Inferior membranes can easily lead to cracks in the weld and have a short service life.
