I-Nylon (i-Polyamide, i-PA) iyipulasitiki yobunjiniyela esebenza kahle kakhulu esetshenziswa kakhulu kuma-elekthronikhi, ezimotweni, ezindwangu, nakweminye imikhakha. Ngenxa yokusha kwayo, ukuguqulwa kwe-nylon evimbela ilangabi kubaluleke kakhulu. Ngezansi umklamo oningiliziwe kanye nencazelo yezakhiwo ze-nylon evimbela ilangabi, ezihlanganisa izixazululo ze-halogenated kanye ne-halogen-free flame retardant.
1. Izimiso Zomklamo Wokwenza I-Nylon Flame Retardant
Ukwakheka kwezakhi zokuvimbela umlilo ze-nylon kufanele kuhambisane nezimiso ezilandelayo:
- Ukumelana Nokushisa Okuphezulu: Hlangana nezindinganiso ze-UL 94 V-0 noma ze-V-2.
- Ukusebenza Kokucubungula: Izinto ezivimbela ilangabi akufanele zithinte kakhulu izakhiwo zokucubungula ze-nylon (isb., ukugeleza kwamanzi, ukuqina kokushisa).
- Izakhiwo Zemishini: Ukwengezwa kwezinto ezivimbela ilangabi kufanele kunciphise umthelela emandleni enayiloni, ukuqina kwayo, kanye nokumelana nokuguguleka kwayo.
- Ubungane Bemvelo: Beka phambili izinto ezivimbela ilangabi ezingenayo i-halogen ukuze zihambisane nemithethonqubo yezemvelo.
2. Ukwakheka kwe-Nylon Evimbela Umlilo Ene-Halogenated
Izinto ezivimbela ilangabi ezifakwe i-halogenated (isb., izinto ezihlanganisiwe) ziphazamisa ukusabela kweketanga lokushiswa ngokukhulula ama-halogen radicals, okunikeza ukusebenza kahle okuphezulu kokuvimbela ilangabi.
Ukwakheka Kokwakheka:
- I-resin ye-nylon (i-PA6 noma i-PA66): 100 phr
- I-brominated flame retardant: 10–20 phr (isb., i-decabromodiphenyl ethane, i-polystyrene ene-brominated)
- I-antimony trioxide (i-synergist): 3–5 phr
- Isithambisi: 1–2 phr (isb., i-calcium stearate)
- I-Antioxidant: 0.5–1 phr (isb., 1010 noma 168)
Izinyathelo Zokucubungula:
- I-premix nylon resin, i-flame retardant, i-synergist, i-lubricant, kanye ne-antioxidant ngokufanayo.
- Ncibilikisa ingxube usebenzisa i-extruder enama-screw amabili bese uyixuba.
- Lawula izinga lokushisa lokukhipha ku-240–280°C (lungisa ngokusekelwe kuhlobo lwe-nylon).
Izici:
- Izinzuzo: Ukusebenza kahle kokushisa ilangabi okuphezulu, inani eliphansi lokwengeza, futhi kuyabiza.
- Ukungalungi: Ukukhishwa okungenzeka kwamagesi anobuthi ngesikhathi sokusha, izinkinga zemvelo.
3. Ukwakheka kwe-Nylon Engadingi I-Halogen-Flame Retardant
Izinto ezivimbela ilangabi ezingenayo i-halogen (isb., ezisekelwe ku-phosphorus, ezisekelwe ku-nitrogen, noma ama-hydroxide angaphili) zisebenza ngokusabela kwe-endothermic noma ukwakheka kwezingqimba ezivikelayo, okunikeza ukusebenza okungcono kwemvelo.
Ukwakheka Kokwakheka:
- I-resin ye-nylon (i-PA6 noma i-PA66): 100 phr
- Isivimbeli somlilo esisekelwe ku-phosphorus: 10–15 phr (isb., i-ammonium polyphosphate APP noma i-phosphorus ebomvu)
- Isivimbeli somlilo esisekelwe ku-nitrogen: 5–10 phr (isb., i-melamine cyanurate MCA)
- I-hydroxide engakhiqizi: 20–30 phr (isb., i-magnesium hydroxide noma i-aluminium hydroxide)
- Isithambisi: 1–2 phr (isb., i-zinc stearate)
- I-Antioxidant: 0.5–1 phr (isb., 1010 noma 168)
Izinyathelo Zokucubungula:
- I-premix nylon resin, i-flame retardant, i-lubricant, kanye ne-antioxidant ngokufanayo.
- Ncibilikisa ingxube usebenzisa i-extruder enama-screw amabili bese uyixuba.
- Lawula izinga lokushisa lokukhipha ku-240–280°C (lungisa ngokusekelwe kuhlobo lwe-nylon).
Izici:
- Izinzuzo: Inobungani nemvelo, ayikhiphi igesi enobuthi, ihambisana nemithethonqubo.
- Ukungalungi: Ukusebenza kahle okuphansi kokuvimbela umlilo, amanani aphezulu okwengezwayo, umthelela ongaba khona ezimpahleni zemishini.
4. Izinto Ezibalulekile Okufanele Zicatshangelwe Ekwakhiweni Kwefomula
(1) Ukukhetha Okungalawuli Ilanga
- Izinto ezigcina ilangabi ezifakwe i-halogen: Ukusebenza kahle kakhulu kodwa kunezingozi zemvelo nezempilo.
- Izinto ezivimbela ilangabi ezingenayo i-halogen: Ivikela imvelo kodwa idinga inani elikhulu futhi ingathinta ukusebenza kwezinto ezibonakalayo.
(2) Ukusetshenziswa kwama-Synergists
- I-antimony trioxide: Isebenza ngokubambisana nezithiyo zomlilo ezine-halogenated ukuze kuthuthukiswe ukuthiyo zomlilo.
