European Advances in Fluorine Plastics Processing Technology

Elongation rate is good and blow molding complex shapes of the ideal raw material. THV blow molding itself,[link widoczny dla zalogowanych], but it is usually common with the polyolefin plastic blow molding,[link widoczny dla zalogowanych], polyolefin plastic container to provide a complete structure,[link widoczny dla zalogowanych], THV fluoroplastic improve chemical resistance and anti-permeability. (2) injection molding pellets can be used for injection molding THV, THV fluoropolymer plastic injection molding than any other low temperature (at 200 ℃ ~ 300 ℃). THV can use conventional plastic injection molding machine processing. General conditions such as injection molding shown in Table 4. Table 4THV characteristics of injection molding processing temperature / ℃ characteristics of raw materials,[link widoczny dla zalogowanych], processing characteristics of the control screw melting point of 115 to 180 square tooth shape from a single screw injection pressure / MPa172 moisture content of <1, the melt processing of 200 to 300 large tb / (L / D ) 15; 1 to 28; a clamping force corresponding to the injection pressure drying recommended dry, but not always need to die 6O ~ 100 diameter / ram28 back down coloring THV fluoroplastic can be colored compression ratio of 2:1 ~ 3:1 injection speed 3 ~ 1O THV fluoroplastic can be any recovery ratio (low compression screw) / (mm / s) cases with recycled and new materials coupled with 7-_E. Aspect ratio of 23:15 Guarniflon company Guarniflon City is located in Bergamo, Italy, the main production of Teflon suspended material products, annual output of 2,700 tons in 2001, the main products are PTFE sheet, rod, tube, film, O-ring, piston ring, oriented with the other, the domestic manufacturers of similar products with similar, but more the following characteristics of products and technologies. A 56-5.1SC grade silicon carbide products, which is a filled PTFE sealing material, PTFE products with both high temperature, corrosion resistance and other characteristics, but also improve its mechanical properties, creep resistance, are replaced asbestos a better material, widely used in chemical, petroleum, food, paper and other fields. Table 5 shows the SC-level product classification. Plastic Deformation Analysis of Injection Molded Parts 32 2003 No. 4 Table 5SC-level performance SC1600 Product Name Product temperature use, more flexible, for medium acidity, used in the food industry for high temperature, high pressure, strong acid solvents, used in heat exchangers, SC1400 hydrogenation process, paper and other research and development of the product SC1300 molding method has some difficulties, it is necessary to join the hard silicon carbide, mechanical pressure to improve their performance, but also to keep it soft sealing materials. Which may add some kind of pore forming agent, under certain conditions and then be precipitated, to some kind of foam products to the character, meet the requirements. 5.2CALFILM This is developed in a 1998 film products, with heat, deformation, corrosion resistance, slip resistance, high voltage, shielding and good characteristics, and self-adhesive, easy to use, used in food, machinery, electronics, aviation, and other fields. Products Table 6. Name of Product Characteristics Table 6Calfilm GFZ ultra smooth thin film composite insulating tape GF PSA high modulus, pressure sensitive insulation with GF. 481 High insulation may be turning with the product and then through the rolling, single pull handle, with a single strength, stability enhancement difficult to damage, and increase transparency. After the film surface to reduce the through-hole pressure to improve the electrical properties. 5.3 Guarniflon PTFE surface treatment technology company developed a PTFE surface treatment technology (also translated as etching), through the use of chemical solvents on the PTFE surface etching, you can stick with a particular then agents will PTFE and metal, rubber, plastics, etc. together. No difference in the bonding at the uniform, the process safety and no pollution, no residue processing surface cleaning can be handled on both sides, after the warranty period of up to 1O ~ 12 months, and for pure PTFE and filled PTFE. Very characteristic of the technology to improve the currently used sodium naphthalene treatment method for a number of shortcomings, such as the operation of non-polluting, and do not have to immediately after bonding, practical, strong.
