According to the pipe diameter, it can be divided into two types: ordinary pipe and micro pipe. Main equipment: mixer, preformer, vertical pusher, drying and sintering furnace. Ordinary tube inner diameter PTFE adhesive tape Manufacturers 4mm, micro tube inner diameter 4mm. Production process parameters: Mixing: temperature 19℃, time 10min-20min, after mixing, park at 25℃-30℃ for more than 24h. Continuous sintering, drying zone 100℃-250℃, preheating zone 250℃-330℃, sintering zone 380℃-420℃, cooling zone less than 300℃. The pressing rate decreases with the increase of pipe diameter, and accelerates with the decrease of wall thickness.Drying: Below 210℃, 2h-3h. Typical formula for producing PTFE pipe: Disperse PTFE resin 100 (parts by weight) Extrusion aid 18-24 Production process: PTFE, extrusion aid.Main technical indicators: ZBG-33001-85, see table. Billet making: compression rate is about 50mm/min, pressure 0-3MPa. Pushing: The temperature of the material cavity is 30℃-50℃, and the temperature of the die is 50℃-60℃.The ordinary PTFE tube is made of polytetrafluoroethylene dispersed resin at room temperature with organic solvent as the extrusion aid, and then dried and sintered
