Lanxi City Ruifeng Plastic Factory to introduce you to the preparation method of isotactic polypropylene fibers. Polypropylene fiber forming melt spinning method usually used (see melt spinning). To reduce swelling and avoid melt fracture aperture is usually chosen larger spinneret hole diameter (0.5 to 0.8 mm), and raise the aspect ratio of the nozzle hole. The melt spinning temperature is usually higher than the melting point of about 100 ℃ candles retail base, which is about 270 ℃ spinning. Lanxi City Ruifeng Plastic Factory to introduce you to the preparation method of isotactic polypropylene fibers. Such as adding a small amount of additives in the polypropylene resin, such as nitrogen or oxygen stable free radical compounds, such as the method of wholesale candle base and polyester blend spinning, spinning may be appropriate to reduce the temperature of the candle base foreign trade, improve the rheological properties of the melt. And other low glass transition temperature gauge polypropylene fibers (about -18 ℃), crystallization ability, to make the spun fiber to maintain a certain degree of orientation and crystallinity, shall strengthen and strictly controlled cooling extruded strands forming conditions . Quality candle base, Guizhou candle base, Ruifeng Plastic Factory notoriety by Lanxi City Ruifeng Plastic Factory.
