Ukuqulunqwa koqulunqo:
- Inayiloni resin (PA6 okanye PA66): 100 phr
- I-phosphorus-based flame retardant: 10–15 phr (umz., ammonium polyphosphate APP okanye i-phosphorus ebomvu)
- I-nitrogen esekelwe kwi-flame retardant: 5-10 phr (umzekelo, i-melamine cyanrate MCA)
- I-Inorganic hydroxide: 20–30 phr (umzekelo, i-magnesium hydroxide okanye i-aluminiyam hydroxide)
- I-Lubricant: 1–2 phr (umzekelo, i-zinc stearate)
- I-Antioxidant: 0.5–1 phr (umz., 1010 okanye 168)
Amanyathelo Okulungisa:
- I-Premix ye-nylon resin, i-flame retardant, i-lubricant, kunye ne-antioxidant ngokufanayo.
- Nyibilikisa-udibanise usebenzisa i-twin-screw extruder kunye ne-peltize.
- Lawula ubushushu be-extrusion kwi-240-280 ° C (lungisa ngokusekelwe kuhlobo lwenayiloni).
Iimpawu:
- Iingenelo: Ubuhlobo bendalo, akukho kukhutshwa kwegesi eyityhefu, ehambelana nemimiselo.
- Iingxaki: Ukusebenza okuphantsi kwe-flame retardant, izixa eziphezulu zokongeza, impembelelo enokubakho kwiipropati zoomatshini.
