Embodiment 1
[0025] Put the PET chips in the twin-screw extruder, set the process parameters of the extruder, and then turn on the machine for extrusion and granulation. The long glass fibers are added from the glass fiber feeding port of the twin-screw extruder. The number of strands added for 1 share. After the material strip is pulled smoothly, keep all the processing parameters unchanged, place the glass fiber on the electronic scale, measure the same sampling time with a chronograph stopwatch for 1 minute, and record the weight reduction of the long glass fiber within 1 minute. At the same time, at the feed port of the twin-screw extruder, the feed was fed for 1 minute, and the weight of the feed was weighed with an electronic scale. Then divide the long glass fiber reduction by the material weight to get the long glass fiber filling, and compare it with the empirical value and the combustion test value. The long glass fiber is the long glass fiber produced by Taishan Glass Fiber Co....
Embodiment 2
[0027] Basically the same as embodiment 1, the difference is: the same sampling time measured by the chronograph stopwatch is 2 minutes.
Embodiment 3
[0029] Basically the same as embodiment 1, the difference is: the same sampling time measured by a chronograph stopwatch is 5 minutes.
