- Inorganic hydroxide: 20-30 phr (mohlala, magnesium hydroxide kapa aluminium hydroxide)
- Lubricant: 1-2 phr (mohlala, zinc stearate)
- Antioxidant: 0.5–1 phr (mohlala, 1010 kapa 168)
Mehato ea Ts'ebetso:
- Premix nylon resin, flame retardant, lubricant, le antioxidant ka mokhoa o ts'oanang.
- Qhibiliha ka ho sebelisa twin-screw extruder le pelletize.
- Laola mocheso oa extrusion ho 240-280 ° C (fetola ho latela mofuta oa nylon).
Litšobotsi:
- Melemo: E na le tikoloho, ha e na khase e chefo, e lumellanang le melao.
- Mefokolo: Ts'ebetso e tlase ea ho khutlisa lelakabe, palo e phahameng ea tlatsetso, tšusumetso e ka bang teng ho thepa ea mochini.
4. Lintlha tsa Bohlokoa ho Moralo oa Tlhahiso
(1) Khetho e Lekang Lelakabe
- Li-halogenated flame retardants: Ho sebetsa hantle haholo empa ho beha likotsi tsa tikoloho le bophelo bo botle.
- Li-flame retardants tse se nang Halogen: Eco-friendly empa e hloka chelete e ngata 'me e ka ama ts'ebetso ea thepa.
(2) Tšebeliso ea Li-Synergists
- Antimony trioxide: E sebetsa ka tumellano le li-halogenated flame retardants ho matlafatsa ho lieha ha lelakabe.
- Synergy ea phosphorus-nitrogen: Litsamaisong tse se nang halogen, li-flame retardants tse thehiloeng ho naetrojene li ka kopanya ho ntlafatsa ts'ebetso.
(3) Phatlalatso le Ts'ebetso
- Li-disperants: Etsa bonnete ba ho hasana ka mokhoa o ts'oanang oa li-retardants tsa malakabe ho qoba libaka tse phahameng tsa libaka.
- Lisebelisoa: Ntlafatsa ho sebetsa ha metsi le ho fokotsa ho roala ha lisebelisoa.
(4) Li-antioxidants
Thibela ho senyeha ha thepa nakong ea ho sebetsa le ho matlafatsa botsitso ba sehlahisoa.
5. Likopo tse Tloaelehileng
- Tsa elektroniki: Likarolo tse thibelang malakabe joalo ka likhokahanyo, li-switches le li-sockets.
- Tsa makoloi: Li-phr tse thibelang malakabe joalo ka likoahelo tsa enjene, lithapo tsa likhoele, le likarolo tsa kahare.
- Lisebelisoa: Likhoele le masela a thibelang mollo.
6. Litlhahiso tsa ho ntlafatsa ho theha
(1) Ho Ntlafatsa Tšebeliso e Ntle ea Flame Retardant
- Motsoako o thibelang malakabe: Halogen-antimony kapa phosphorus-nitrogen synergies ho ntlafatsa tshebetso.
- Nano flame retardants: Mohlala, nano magnesium hydroxide kapa letsopa la nano, ho ntlafatsa ts'ebetso le ho fokotsa palo ea tlatsetso.
(2) Ho Ntlafatsa Thepa ea Mechini

- Ho matlafatsa li-fillers: Mohlala, fiber ea khalase, ho ntlafatsa matla le ho tiea.
(3) Phokotso ea Litšenyehelo
- Ntlafatsa likhakanyo tse thibelang malakabe: Fokotsa ts'ebeliso ha u ntse u kopana le litlhoko tsa ho lieha ha malakabe.
- Khetha thepa e bolokang chelete e ngata: Mohlala, li-retardants tsa lelakabe tsa lapeng kapa tse tsoakiloeng.
7. Litlhoko tsa Tikoloho le Taolo
- Li-halogenated flame retardants: E thibetsoe ke RoHS, REACH, joalo-joalo, e hlokang tšebeliso e hlokolosi.
- Li-flame retardants tse se nang Halogen: E lumellana le melaoana, e emelang mekhoa e tlang.
Moralo oa litlolo tse thibelang lelakabe la nylon o lokela ho nahana ka maemo a ikhethileng a ts'ebeliso le litlhokahalo tsa taolo ha o khetha li-halogenated kapa tse se nang halogen flame retardants. Li-halogenated flame retardants li fana ka ts'ebetso e phahameng empa li beha likotsi tsa tikoloho, athe mefuta e meng e se nang halogen e sebetsa hantle ka tikoloho empa e hloka likhakanyo tse kholoanyane. Ka ho ntlafatsa litlhophiso le lits'ebetso, lisebelisoa tsa nayilone tse sebetsang hantle, tse baballang tikoloho, le tse bolokang chelete e ngata tse sa cheseheng mollo li ka ntlafatsoa ho fihlela litlhoko tsa lisebelisoa tsa elektroniki, tsa makoloi, tsa masela le liindasteri tse ling.
