1. Common processing technology of fluorine rubber1. Injection molding: The fluororubber using this process can adopt low and medium Mooney viscosity (20-60MV), good scorch safety and fast vulcanization speed.2. Injection compression molding: The fluororubber using this process can adopt low Mooney viscosity and medium Mooney viscosity (20-60MV), and the grade with good scorch safety, so as to avoid scorch during the injection process.3. Flat compression molding: The fluororubber using this process can adopt the brand with high Mooney viscosity (50-90MV) and fast vulcanization speed.4. Extrusion molding: The fluorine rubber using this process can adopt low Mooney viscosity (20-40MV) and good scorch safety grades. In many cases processing aids can be used to improve flow and surface finish.5. Coating and forming: the viscosity of the solution is determined by the selected solvent and the amount of filler. The stability (shelf life) of the solution is the primary issue to be considered.―Second stage vulcanization: In order to achieve the best performance, the rubber is finally subjected to two stage vulcanization. The general two-stage vulcanization condition is 230°C×24h. However, the time and temperature of secondary vulcanization vary with different products, processes and costs. for some applications. Secondary vulcanization may not be used.Second, the application field of fluorine rubberAutomobile, aerospace, petrochemical and machinery industries are the most widely used fields of fluororubber, and 60% to 70% of fluororubber is used in the automotive industry. Relevant regulations for automobiles will have a profound impact on the application of fluoroelastomers. The biggest challenge for the fluoroelastomer manufacturing industry is to help the automotive industry find better and less permeable sealing materials to meet stringent new automotive emissions standards. Fuel system and engine gasket manufacturers have long focused on fluoroelastomers for fuel and drivetrain gaskets, hoses, engine air intakes and oil-resistant gaskets. At present, my country's fluorine rubber is facing good opportunities for development.

Technical application:This technology is a new type of sealing structure developed after studying the special working conditions of the damper cylinder, which can solve the common phenomenon that the seals of the damper are easy to leak and not resistant to high temperature.Technical points:1. According to the long-life requirements of the building damper, the seal material with good durability and weather resistance is selected: the base material of the seal is made of special polytetrafluoroethylene modified composite material, and the spring is made of special stainless steel material.2. A special sealing lip is designed according to the high viscosity characteristics of the working medium, and an O-shaped spring is used to strengthen the support of the lip and prevent sealing leakage.3. To prevent the seal from being eccentric, the structure of double grooves and double springs is adopted.Technical advantages:1, Special sealing lip and strong supporting spring structure can scrape off the working medium adhering to the piston rod to prevent seal leakage.2, Double spring structure, can adapt to the eccentric movement of the piston rod, enhance the anti-eccentric ability of the seal, and prolong the working life.3, Ideal material selection to ensure low friction and long life of the seal.Patent No.: 2016110518228 2016212690229

Technical application:This structure overcomes the contradiction between the sealing effect and the movement resistance of the general oil cylinder sealing structure, and can achieve a good seal while reducing the movement friction resistance, effectively improving the output efficiency of the oil cylinder, and the seal is easy to install.Technical points:1. The main body of the seal is a Teflon slip ring (one end of the slip ring structure is thicker and the other end is thin, and the thin end is the lip), and rubber and other elastic elements are used to provide sealing force and wear supplement.2. Innovative piston seal installation structure, the two main sealing lips of the piston are installed facing each other, which is convenient for installation.3. There is only one seal for the piston rod, with low friction and low resistance.Technical advantages:1. The friction contact surface of the oil cylinder seal is made of Teflon material, and the friction coefficient is small.2. The structure of the thin lip is easy to change, and it can fit regardless of the internal pressure, and the internal leakage is extremely small.3. Teflon material sealing system has good medium adaptability and longer working life.4. The seal is easy to install and can be installed without any tooling.5. The system resistance is low, which can solve the defects of ordinary oil cylinders such as crawling, shaking, and abnormal noise.Patent No.: 201721923909X 2017114635672Scope of application and solution to pain points: crawling, shaking, low resistance and long-term effect

Technical application:This technology can scrape off hard objects such as ice slag and cement solidification attached to the piston rod of construction machinery, avoid damage to the cylinder seal by hard objects, and prolong the life of the oil cylinder.Technical points:1. Polyoxymethylene is used as the base material, which has high hardness, small friction coefficient and good wear resistance.2. O-shaped spring provides preload.3. Double lip structure.Technical advantages:1. The hardness of the matrix material is relatively high, which can scrape off hard objects such as cement slag and ice slag attached to the piston rod;2. The O-shaped sheet spring has a large resilience, and the lip is close to the piston rod to scrape off the dust particles in the general environment.3. The matrix material has a small friction coefficient and good wear resistance, which can prolong the service life of the dust seal.4. The double-lip structure scrapes dust more cleanly.
