poly(chlorotrifluoroethylene) - Molding Process
Open Data Verified Data
- Polychlorotrifluoroethylene can be processed by a molding method of a general thermoplastic. However, since its viscosity in the molten state is still as high as several kilopascals-seconds, it is necessary to have sufficient processing fluidity at a relatively high temperature, and therefore a higher processing temperature and pressure are required. In addition, because the processing temperature (250~320 deg C) and decomposition temperature (about 300 deg C) is very close, so the processing temperature range is very narrow, should be noted. Specific molding processing methods include molding, injection molding, extrusion and coating. Can be made of film, pipe, bar, plate, etc. Molding due to high temperature will cause the decomposition of the resin, the release of corrosive acid gas, so the mold should be used corrosion resistant alloy materials or the use of high quality nickel chromium alloy, or with tool steel and then plated with hard chromium. The process conditions are as follows: the molding temperature is 220~240 ℃ (10~30 ℃ lower than that of common resin); The hot pressing pressure is 1~4. 9MPa; Cold pressure is 9.8~29. 4MPa; Heating time according to the thickness of the product, the thickness of 5mm when the heating time is 15min,lOmm is 35min,15mm is 50min.
- During extrusion molding, the screw aspect ratio (L/D) is ≥ 20, the compression ratio is (2:1) to (3:1), and the screw rotation speed is 15 to 20 r/min. When the pipe is produced, the processing temperature is 250 ° C. After the cylinder, 290 ° C. Before the cylinder, 320 ° C. After the mold, and 340~350 ° C. Before the mold. When producing thin tubes, emergency cold, and thick wall parts should be slow cold, so as to avoid bubbles. The mold temperature during injection molding was 130 to 150 ° C., and the pressure was 147 to 196MPA. Polychlorotrifluoroethylene suspension can be applied by dipping, spraying, pouring and brushing. Take spraying as an example. The coating process conditions are as follows: the diameter of the spray gun is sound 1. 5mm, the number of primer spraying is 1~2 layers, the number of fabric spraying is 6~7 layers, the distance between the spray gun and the spray piece is 10 ~ 20cm, and the moving speed of the spray gun is about 8 m/min, the oven temperature was 270 °c.
