Nylon (Polyamide, PA) bụ plastik injinia na-arụ ọrụ dị elu nke a na-ejikarị na ngwa elektrọnik, ụgbọ ala, akwa na mpaghara ndị ọzọ. N'ihi ire ọkụ ya, ngbanwe naịlọn na-egbochi ire ọkụ dị mkpa nke ukwuu. N'okpuru ebe a bụ nkọwa zuru ezu na nkọwapụta nke usoro ire ere naịlọn, na-ekpuchi ma halogenated na halogen na-enweghị ihe mgbochi ire ọkụ.
1. Ụkpụrụ nke Nylon Flame Retardant Formulation Design
Nhazi nke usoro ire ere naịlọn kwesịrị ịgbaso ụkpụrụ ndị a:
- Ọkụ na-adịgide adịgide: Zute ụkpụrụ UL 94 V-0 ma ọ bụ V-2.
- Ịrụ ọrụ nhazi: Ndị na-ere ọkụ ekwesịghị imetụta njirimara nhazi naịlọn nke ukwuu (dịka ọmụmaatụ, mmiri mmiri, nkwụsi ike ọkụ).
- Ihe eji arụ ọrụ: Mgbakwụnye nke ire ere kwesịrị ibelata mmetụta na ike naịlọn, ike siri ike na nguzogide eyi.
- Enyi na gburugburu ebe obibi: Nyefee ndị na-ere ọkụ na-enweghị halogen ụzọ ka ha rube isi n'iwu gburugburu ebe obibi.
2. Ngwakọta naịlọn na-egbochi ọkụ halogenated
Ndị na-ere ọkụ halogenated (dịka ọmụmaatụ, ogige brominated) na-akwụsị mmeghachi omume nrụnye combustion site n'ịhapụ halogen radicals, na-enye nnukwu ọkụ retardant arụmọrụ.
Ihe mejupụtara:
- resin nylon (PA6 ma ọ bụ PA66): 100 phr
- Ọkụ na-egbochi ire ọkụ: 10–20 phr (dịka ọmụmaatụ, decabromodiphenyl ethane, polystyrene brominated)
- Antimony trioxide ( synergist): 3–5 phr
- Mmanu mmanu: 1-2 phr (dịka ọmụmaatụ, calcium stearate)
- Antioxidant: 0.5–1 phr (dịka, 1010 ma ọ bụ 168)
Usoro nhazi:
- Premix naịlọn resin, ire ọkụ retardant, synergist, mmanu, na antioxidant n'otu n'otu.
- Gbazee-agwakọta site na iji ejima-skru extruder na pelletize.
- Control extrusion okpomọkụ na 240-280 Celsius (dozie dabere na ụdị naịlọn).
Njirimara:
- Uru: Nnukwu ọkụ retardant arụmọrụ, obere mgbakwunye ego, na-eri-irè.
- Ọdịmma: Enwere ike ịhapụ gas na-egbu egbu n'oge ọkụ, nchegbu gburugburu ebe obibi.
3. Ngwakọta naịlọn na-egbochi ọkụ halogen-efu
Ndị na-ere ọkụ na-enweghị halogen (dịka ọmụmaatụ, sitere na phosphorus, dabere na nitrogen ma ọ bụ inorganic hydroxides) na-arụ ọrụ site na mmeghachi omume endothermic ma ọ bụ nhazi oyi akwa, na-enye arụmọrụ gburugburu ebe obibi ka mma.
Ihe mejupụtara:
- resin nylon (PA6 ma ọ bụ PA66): 100 phr
- Nkwụghachi ọkụ nke sitere na phosphorus: 10–15 phr (dịka ọmụmaatụ, ammonium polyphosphate APP ma ọ bụ phosphorus na-acha uhie uhie)
- Ọkụ na-egbochi Nitrogen: 5-10 phr (dịka, melamine cyanurate MCA)
- Inorganic hydroxide: 20-30 phr (dịka ọmụmaatụ, magnesium hydroxide ma ọ bụ aluminum hydroxide)
- Mmanu mmanu: 1-2 phr (dịka ọmụmaatụ, zinc stearate)
- Antioxidant: 0.5–1 phr (dịka, 1010 ma ọ bụ 168)
Usoro nhazi:
- Premix naịlọn resin, ire ọkụ, mmanu, na antioxidant n'otu n'otu.
- Gbazee-agwakọta site na iji ejima-skru extruder na pelletize.
- Control extrusion okpomọkụ na 240-280 Celsius (dozie dabere na ụdị naịlọn).
Njirimara:
- Uru: Enyi na gburugburu ebe obibi, enweghị ikuku gas na-egbu egbu, na-agbaso ụkpụrụ.
- Ọdịmma: Lower ire retardant arụmọrụ, elu mgbakwunye ichekwa, nwere ike mmetụta na n'ibu Njirimara.
4. Ihe ndị dị mkpa na nhazi nhazi
(1) Nhọrọ na-egbochi ire ọkụ
- Halogenated ire ọkụ retardants: Oke arụmọrụ mana na-ebute ihe egwu gburugburu ebe obibi na ahụike.
- Ihe mgbochi ọkụ na-enweghị halogen: Eco-enyi na enyi mana ọ chọrọ nnukwu ego ma nwee ike imetụta arụmọrụ ihe.
(2) Iji Synergists
- Antimony trioxide: Na-arụ ọrụ synergistically na halogenated ire ọkụ retardants iji welie ire retardant.
- Phosphorus-nitrogen mmekọrịta: N'ime sistemu na-enweghị halogen, ndị na-egbochi ire ọkụ sitere na phosphorus na nitrogen nwere ike imekọrịta ọnụ iji melite arụmọrụ.
(3) Mgbasa na nhazi
- Ndị na-ekesa: Gbaa mbọ hụ na mgbasa nke ire ọkụ na-agbaze n'otu n'otu ka ịzenarị nnukwu mkpokọta mpaghara.
- Mmanụ aṅụ: Mma nhazi nhazi ma belata akụrụngwa akụrụngwa.
(4) Antioxidants
Gbochie mmebi ihe n'oge nhazi ma kwalite nkwụsi ike ngwaahịa.
5. Ngwa a na-ahụkarị
- EletrọnịkịIhe ndị na-egbochi ire ọkụ dị ka njikọ, mgba ọkụ, na sọket.
- Ụgbọala: phr na-egbochi ire ọkụ dị ka mkpuchi injin, ihe nkedo wiring na ihe ndị dị n'ime.
- Akwa akwa: eriri na akwa na-egbochi ire ọkụ.
6. Ntụnye nkwalite nhazi nhazi
(1) Ịkwalite arụmọrụ ire ọkụ
- Ngwakọta ire ere: Halogen-antimony ma ọ bụ phosphorus-nitrogen synergies iji melite arụmọrụ.
- Nano ire ọkụ retardants: Dịka ọmụmaatụ, nano magnesium hydroxide ma ọ bụ ụrọ nano, iji kwalite arụmọrụ ma belata ihe mgbakwunye.
(2) Imelite akụrụngwa akụrụngwa
- Ndị siri ike: Dịka, POE ma ọ bụ EPDM, iji welie ihe siri ike na nguzogide mmetụta.
- Na-eme ka ihe ndozi dị ike: Dịka ọmụmaatụ, eriri iko, iji meziwanye ike na isi ike.
(3) Mbelata ọnụ ahịa
- Welie oke nkwụghachi ọkụ: Wedata ojiji ka ị na-emezu ihe achọrọ nkwụghachi ọkụ.
- Họrọ ihe ndị dị ọnụ ahịa: Dịka ọmụmaatụ, ihe mgbochi ire ọkụ nke ụlọ ma ọ bụ agwakọta.
7. Ihe ndị chọrọ gburugburu ebe obibi na usoro iwu
- Halogenated ire ọkụ retardants: Amachibidoro site na RoHS, REACH, wdg, chọrọ iji nlezianya mee ihe.
- Ihe mgbochi ọkụ na-enweghị halogen: Dabere na ụkpụrụ, na-anọchite anya ọnọdụ n'ọdịnihu.
Nhazi nke usoro ire ere naịlọn kwesịrị ịtụle ọnọdụ ngwa ngwa yana ihe achọrọ mgbe ị na-ahọrọ ihe mgbochi ire ọkụ na-enweghị halogen ma ọ bụ halogen. Ndị na-ere ọkụ halogenated na-enye arụmọrụ dị elu mana na-ebute ihe egwu gburugburu ebe obibi, ebe ndị ọzọ na-enweghị halogen bụ enyi na enyi mana ọ chọrọ nnukwu mgbakwunye. Site n'ịkwalite usoro na usoro, a ga-emepụta ihe naịlọn nke na-eme ka ọ dị mma, nke na-akwado gburugburu ebe obibi na nke dị ọnụ ahịa iji gboo mkpa nke ngwá electronic, ụgbọala, textiles na ụlọ ọrụ ndị ọzọ.
