Perfluoroether rubber can withstand corrosion from over 1,600 chemical solvents, including strong acids, strong alkalis, organic solvents, ultra-high-temperature steam, ethers, ketones, esters, nitrogen compounds, hydrocarbons, alcohols, aldehydes, furans, amine compounds, and more. It can endure temperatures up to 320°C. FFKM perfluoroether components have been used in numerous industries for nearly 40 years with practical application experience.Rubber Seal Ring Sealing Pressure Test Method:This test method measures the pressure exerted by the seal on the material installed in its groove, simulating actual usage conditions. It measures the force required to open the seal lip to the thickness of the material it seals. For double-groove seals, this method involves inserting a metal restrictor of specified thickness into one groove and conducting the test on the other groove. Thus, the test results reflect the pressure of the sealing lip during use.Equipment:1. Tensile testing machine, compliant with HG/T2369 requirements, with B-grade accuracy.2. Fixture3. Lip separator, made of stainless steel, used for molded corner specimens4. Metal restrictor, used when testing double-groove seals. Its width should match the specimen's width, and its thickness should match the installed material's thickness.Extruded specimens should be actual seal pieces with a length of at least 20mm but not more than 305mm. At least four specimens per batch should be tested.Corner specimens should have both sides measuring 25mm from the inner corner. At least four specimens per batch should be tested.An important step in production is vulcanization, which transforms the linear polymer structure into a three-dimensional polymer structure. Sulfur forms covalent bonds between two polymer chains, creating a three-dimensional structure and enhancing the rubber's properties. Therefore, controlling vulcanization is crucial. However, before vulcanization, the rubber must undergo mixing, adding vulcanizing agents and reinforcing agents to improve its properties.Benefits of Vulcanized Rubber:It exhibits characteristics such as non-stickiness and resistance to breakage.1.

Company: Shaanxi Deli Energy Technology Co., Ltd.

Product Description: At the same time, Vandelli Boiler, leveraging the inherent advantages of semi-coke while addressing its shortcomings, has fully utilized its benefits and employed proprietary technology to mitigate and resolve its deficiencies. This led to the development of a high-temperature gasification and pyrolysis combustion semi-coke boiler. The principle involves first gasifying the semi-coke to convert it into combustible gas, which is then burned to produce hot water, steam, or heat thermal oil. A key feature of this equipment is that gasification and combustion occur almost simultaneously within microseconds. The rectification plan for coal-fired boilers above 20 tons, announced before October 31, 2016, includes four options: 1. Grid connection: Priority given to boilers meeting grid connection conditions. 2. Natural gas: Preference for natural gas where pipeline networks are available. 3. Installation of desulfurization and denitrification equipment: Retrofitting existing coal-fired boilers with such equipment without replacement. 4. Semi-coke: Converting coal-fired boilers to use semi-coke as a clean energy source. Industry experts recommend that, among these options, boilers capable of grid connection should be prioritized for that solution. For boilers that cannot be connected to the grid, converting coal-fired boilers to semi-coke boilers is the preferred alternative. This approach significantly reduces both equipment investment and operational costs while fully complying with environmental emission standards. As a clean fuel, semi-coke produces lower levels of SO2, NOx, dust, and heavy metals during combustion compared to raw coal. Its post-combustion emissions meet environmental requirements and have been recognized as a clean energy source by the National Development and Reform Commission and the Hebei Provincial Government, exempting it from coal consumption quotas. Semi-coke boasts a high calorific value of 6,200 kcal/kg, an annual production exceeding 100 million tons, and highly competitive pricing. However, due to its low volatile content and unique carbon particle structure, semi-coke faces challenges such as difficulty igniting and incomplete combustion in conventional boilers, which has severely limited its widespread adoption in industrial boilers. more>

The 4KW model offers moderate power, striking a good balance between performance and energy consumption, making it ideal for most standard mining operations. The 5.5KW version provides strong power, suitable for large-scale, high-intensity production, enabling rapid output of large quantities of stemming material and boosting work efficiency.Voltage Specifications:Common voltage options include 380V, 380/660V, and 660–1140V. Selecting the appropriate voltage is crucial and must match the power supply system at the mining site. 380V is a common industrial voltage, suitable for general surface operations or locations without special voltage requirements. Voltage specifications like 380/660V and 660–1140V are more often used in special environments such as underground coal mines.Output Speed:The typical output speed ranges from 20 to 22 meters per minute. Output speed directly affects production efficiency—a higher speed allows for more stemming material to be produced per unit of time. However, if the speed is too high, it may compromise the quality of the stemming material, leading to issues like uneven surface texture or inconsistent density.When selecting a mining stemming machine, it’s important to consider factors such as production requirements comprehensively—no waiting, no delays.
