Inayiloni (i-Polyamide, PA) iyipulasitiki yobunjiniyela esebenza kakhulu esetshenziswa kakhulu kweze-elekthronikhi, ezezimoto, zezindwangu nakweminye imikhakha. Ngenxa yokuvutha kwayo, ukuguqulwa kwe-nayiloni kwe-flame retardant kubaluleke kakhulu. Ngezansi kunomklamo nencazelo enemininingwane yokubunjwa kwe-nylon flame retardant, okuhlanganisa kokubili izixazululo ze-halogenated ne-halogen-free flame retardant.
1. Izimiso Zokuklama I-Nylon Flame Retardant Formulation
Idizayini yokubunjwa kwe-nylon flame retardant kufanele ihambisane nalezi zimiso ezilandelayo:
- High Flame Retadancy: Hlangana ne-UL 94 V-0 noma i-V-2 amazinga.
- Icubungula ukusebenza: Izinqamuli zomlilo akufanele zithinte kakhulu izakhiwo zokucubungula inayiloni (isb., uketshezi, ukuzinza kokushisa).
- Izakhiwo Zemishini: Ukwengezwa kwama-flame retardants kufanele kunciphise umthelela emandleni enayiloni, ukuqina, nokumelana nokugqokwa.
- Ubungane Bemvelo: Beka kuqala izinciphisi zamalangabi ezingenalo i-halogen ukuze zihambisane nemithetho yemvelo.
2. Ukwakhiwa Kwenayiloni Ye-Halogenated Flame Retardant
Ama-halogenated flame retardants (isb., izinhlanganisela ze-brominated) aphazamisa ukusabela kweketango lokuvutha ngokukhulula ama-halogen radicals, anikeza ukusebenza kahle kwe-flame retardant.
Ukwakhiwa Kokwakhiwa:
- I-nayiloni resin (PA6 noma i-PA66): 100 phr
- I-brominated flame retardant: 10–20 phr (isb, i-decabromodiphenyl ethane, i-brominated polystyrene)
- I-Antimony trioxide (i-synergist): 3-5 phr
- Okokugcoba: 1–2 phr (isb, calcium stearate)
- I-Antioxidant: 0.5–1 phr (isb, 1010 noma 168)
Izinyathelo Zokucubungula:
- I-Premix inayiloni resin, i-flame retardant, i-synergist, i-lubricant, ne-antioxidant ngokufanayo.
- Hlanganisa i-Melt usebenzisa i-twin-screw extruder kanye ne-peltize.
- Lawula izinga lokushisa le-extrusion ku-240–280°C (lungisa ngokusekelwe ohlotsheni lwenayiloni).
Izici:
- Izinzuzo: Ukusebenza kahle kwe-flame retardant, inani eliphansi lesengezo, elingabizi kakhulu.
- Ukubi: Ukukhishwa okungaba khona kwamagesi anobuthi ngesikhathi sokusha, ukukhathazeka kwemvelo.
3. Ukwakhiwa Kwenayiloni Engabusheki Ilangabi Le-Halogen
Ama-flame retardants angenayo i-halogen (isb., asekelwe ku-phosphorus, e-nitrogen-based, noma ama-inorganic hydroxides) asebenza ngokusabela kwe-endothermic noma ukwakheka kongqimba oluvikelayo, okunikeza ukusebenza okungcono kwemvelo.
Ukwakhiwa Kokwakhiwa:
- I-nayiloni resin (PA6 noma i-PA66): 100 phr
- I-phosphorus-based retardant flame: 10–15 phr (isb, ammonium polyphosphate APP noma i-phosphorus ebomvu)
- I-nitrogen-based retardant flame: 5-10 phr (isb, melamine cyanrate MCA)
- I-Inorganic hydroxide: 20–30 phr (isb, i-magnesium hydroxide noma i-aluminium hydroxide)
- Okokugcoba: 1–2 phr (isb., i-zinc stearate)
- I-Antioxidant: 0.5–1 phr (isb, 1010 noma 168)
Izinyathelo Zokucubungula:
- I-Premix inayiloni resin, i-flame retardant, i-lubricant, ne-antioxidant ngokufanayo.
- Hlanganisa i-Melt usebenzisa i-twin-screw extruder kanye ne-peltize.
- Lawula izinga lokushisa le-extrusion ku-240–280°C (lungisa ngokusekelwe ohlotsheni lwenayiloni).
Izici:
- Izinzuzo: Ayihambisani nemvelo, ayikhiphi igesi enobuthi, ehambisana nemithethonqubo.
- Ukubi: Ukusebenza kahle kwe-retardant ye-flame, amanani aphezulu okungeziwe, umthelela ongaba khona ezimpahleni zemishini.
4. Okucatshangelwayo Okubalulekile Emklamweni Wokwakha
(1) Ukukhetha Ukubuyiswa Komlilo
- Ama-halogenated flame retardants: Ukusebenza kahle okuphezulu kodwa kubangela ubungozi bemvelo nempilo.
- Ama-flame retardants angenayo i-halogen: I-Eco-friendly kodwa idinga amanani amakhulu futhi ingase ithinte ukusebenza kwempahla.
(2) Ukusetshenziswa kwama-Synergists
- I-Antimony trioxide: Isebenza ngokubambisana nama-halogenated flame retardants ukuthuthukisa ukulibaziseka komlilo.
- I-Phosphorus-nitrogen synergy: Ezinhlelweni ezingenayo i-halogen, i-phosphorus ne-nitrogen-based flame retardants ingahlanganisa ukuze kuthuthukiswe ukusebenza kahle.
(3) Ukuhlakazeka kanye Nokucubungula
- Abahlakaza: Qinisekisa ukusabalalisa okufanayo kwezinqamuli zomlilo ukuze ugweme ukugxila okuphezulu okwenziwe kwasendaweni.
- Izinto zokugcoba: Thuthukisa ukucubungula uketshezi futhi unciphise ukuguga kwemishini.
(4) Ama-Antioxidants
Vimbela ukonakala kwezinto ngesikhathi sokucubungula futhi uthuthukise ukuzinza komkhiqizo.
5. Izicelo Ezijwayelekile
- Ezogesi: Izingxenye ezingabambezeli ilangabi njengezixhumi, amaswishi, namasokhethi.
- Ezezimoto: I-phr evimbela amalangabi njengamakhava enjini, amahhanisi ezintambo, nezinto zangaphakathi.
- Izindwangu: Imicu nezindwangu ezinganqamuki ilangabi.
6. Izincomo Zokuthuthukisa Ukwakhiwa
(1) Ukuthuthukisa Ukusebenza Kwe-Flame Retardant
- Ukuhlanganiswa kwe-flame retardant: I-Halogen-antimony noma i-phosphorus-nitrogen synergies ukuthuthukisa ukusebenza.
- I-Nano flame retardants: Isb, i-nano magnesium hydroxide noma i-nano clay, ukuthuthukisa ukusebenza kahle nokunciphisa amanani angeziwe.
(2) Ukuthuthukisa Izakhiwo Zemishini

(3) Ukwehliswa Kwezindleko
- Lungiselela izilinganiso zokubuyiswa komlilo: Nciphisa ukusetshenziswa ngenkathi uhlangabezana nezidingo zokuncipha komlilo.
- Khetha izinto ezingabizi kakhulu: Isb, ama-flame retardants asekhaya noma ahlanganisiwe.
7. Izidingo Zemvelo Nezokulawula
- Ama-halogenated flame retardants: Ikhawulelwe yi-RoHS, REACH, njll., edinga ukusetshenziswa ngokuqapha.
- Ama-flame retardants angenayo i-halogen: Ihambisana nemithethonqubo, emele izitayela zesikhathi esizayo.
Idizayini yokubunjwa kwe-nayiloni ye-retardant flame kufanele icabangele izimo ezithile zohlelo kanye nezidingo zokulawula lapho kukhethwa ama-halogenated noma ama-flame retardant angenawo i-halogen. Ama-halogenated flame retardants anikeza ukusebenza kahle okuphezulu kodwa abeka izingozi zemvelo, kuyilapho ezinye izindlela ezingenayo i-halogen zivumelana nemvelo kodwa zidinga amanani amakhulu okungeziwe. Ngokwenza kahle ukwakheka nezinqubo, izinto zenayiloni ezisebenza kahle, ezivumelana nemvelo, nezingabizi kakhulu zingathuthukiswa ukuze zihlangabezane nezidingo zama-electronics, ezezimoto, zendwangu, nezinye izimboni.
