Nigute ushobora gutwika Nylon (Polyamide, PA)?

Nylon (Polyamide, PA) ni plastike yubuhanga ikora cyane ikoreshwa muri electronics, ibinyabiziga, imyenda, nibindi bice. Bitewe no gukongoka kwayo, flame retardant guhindura nylon ni ngombwa. Hano hepfo ni igishushanyo kirambuye hamwe nubusobanuro bwa nylon flame retardant formulaire, ikubiyemo ibisubizo byombi bya halogene na halogen-flame retardant ibisubizo.

1. Amahame ya Nylon Flame Retardant Igishushanyo mbonera

Igishushanyo cya nylon flame retardant formulaire kigomba kubahiriza amahame akurikira:

• Umuriro mwinshi: Kuzuza UL 94 V-0 cyangwa V-2.
• Gutunganya imikorere: Imirasire yumuriro ntigomba kugira ingaruka zikomeye kumitunganyirize ya nylon (urugero, fluidity, stabilite yumuriro).
• Ibikoresho bya mashini: Kwiyongera kwa flame retardants bigomba kugabanya ingaruka kumbaraga za nylon, gukomera, no kwambara.
• Ibidukikije: Shyira imbere abadafite umuriro wa halogene kugirango bakurikize amabwiriza y’ibidukikije.

2. Halogenated Flame Retardant Nylon

Halogenated flame retardants (urugero, ibibyimba bivangwa na bromine) bihagarika urunigi rwo gutwika kurekura halogen radicals, bitanga imikorere yumuriro mwinshi.

Ibigize:

• Nylon resin (PA6 cyangwa PA66): interuro 100
• Brominated flame retardant: interuro 10–20 (urugero, decabromodiphenyl ethane, polystirene ya bromine)
• Antimony trioxide (synergiste): interuro 3-5
• Amavuta yo kwisiga: 1-2 interuro (urugero, calcium stearate)
• Antioxidant: 0.5-1 interuro (urugero, 1010 cyangwa 168)

Intambwe zo Gutunganya:

1. Premix nylon resin, flame retardant, synergist, lubricant, na antioxydeant kimwe.
2. Gushonga-kuvanga ukoresheje twin-screw extruder na pelletize.
3. Kugenzura ubushyuhe bwo gusohora kuri 240-280 ° C (hindura ukurikije ubwoko bwa nylon).

Ibiranga:

• Ibyiza: Flame retardant ikora neza, ingano yinyongera, igiciro-cyiza.
• Ibibi: Ibishobora kurekurwa imyuka yubumara mugihe cyo gutwikwa, impungenge z ibidukikije.

3. Halogen-Yubusa Flame Retardant Nylon

Imirasire ya Halogene idafite (urugero, fosifore, ishingiye kuri azote, cyangwa hydroxide ya organic organique) ikora binyuze mumikorere ya endothermic reaction cyangwa gushiraho urwego rukingira, bitanga imikorere myiza yibidukikije.

Ibigize:

• Nylon resin (PA6 cyangwa PA66): interuro 100
• Fosifore ishingiye kuri flame retardant: 10-15 interuro (urugero, amonium polyphosphate APP cyangwa fosifore itukura)
• Azote ishingiye kuri azote: 5-10 interuro (urugero, melamine cyanurate MCA)
• Hydroxide idasanzwe: interuro 20-30 (urugero, hydroxide ya magnesium cyangwa hydroxide ya aluminium)
• Amavuta: 1-2 interuro (urugero, zinc stearate)
• Antioxidant: 0.5-1 interuro (urugero, 1010 cyangwa 168)

Intambwe zo Gutunganya:

1. Premix nylon resin, flame retardant, lubricant, na antioxydeant kimwe.
2. Gushonga-kuvanga ukoresheje twin-screw extruder na pelletize.
3. Kugenzura ubushyuhe bwo gusohora kuri 240-280 ° C (hindura ukurikije ubwoko bwa nylon).

Ibiranga:

• Ibyiza: Ibidukikije byangiza ibidukikije, nta byuka bihumanya ikirere, byubahiriza amabwiriza.
• Ibibi: Flame retardant ikora neza, ingano yinyongera, ingaruka zishobora kuba kumiterere yubukanishi.

4. Ibyingenzi byingenzi mugushushanya

(1) Guhitamo Flame Retardant Guhitamo

• Halogenated flame retardants: Gukora neza ariko bitera ingaruka kubidukikije nubuzima.
• Halogen-flame retardants: Ibidukikije byangiza ibidukikije ariko bisaba amafaranga menshi kandi birashobora kugira ingaruka kumikorere.

(2) Gukoresha Synergiste

• Antimony trioxide: Akorana hamwe na halogenated flame retardants kugirango yongere umuriro.
• Fosifore-azote ikorana: Muri sisitemu idafite halogene, fosifore na azote ishingiye kuri flame retardants irashobora guhuriza hamwe kugirango irusheho gukora neza.

(3) Gutatana no gutunganywa

• Gutatana: Menya neza ko ikwirakwizwa rya flame retardants kugirango wirinde kwibanda cyane.
• Amavuta: Kunoza uburyo bwo gutunganya no kugabanya ibikoresho.

(4) Antioxydants
Irinde kwangirika kwibintu mugihe cyo gutunganya no kuzamura ibicuruzwa bihamye.

5. Porogaramu zisanzwe

• Ibyuma bya elegitoroniki: Flame-retardant ibice nkibihuza, guhinduranya, na socket.
• Imodoka: Flame-retardant interuro nkibifuniko bya moteri, ibyuma bifata ibyuma, nibice byimbere.
• Imyenda: Flame-retardant fibre nigitambara.

6. Ibyifuzo byo guhitamo neza

(1) Kongera imbaraga za Flame Retardant

• Flame retardant kuvanga: Halogen-antimony cyangwa fosifore-azote ikomatanya kunoza imikorere.
• Nano flame retardants: Urugero, nano magnesium hydroxide cyangwa ibumba rya nano, kugirango byongere imikorere kandi bigabanye inyongeramusaruro.

(2) Kunoza imiterere ya mashini

• Gukomera: Eg, POE cyangwa EPDM, kugirango wongere ubukana bwibintu no kurwanya ingaruka.
• Gushimangira abuzuza: Urugero, fibre fibre, kugirango utezimbere imbaraga no gukomera.

(3) Kugabanya ibiciro

• Hindura ibipimo bya flame retardant: Gabanya imikoreshereze mugihe wujuje ibyangombwa bisabwa.
• Hitamo ibikoresho bikoresha neza: Ingero, urugo cyangwa uruvange rwa flame retardants.

7. Ibidukikije nibisabwa

• Halogenated flame retardants: Bibujijwe na RoHS, REACH, nibindi, bisaba gukoresha ubwitonzi.
• Halogen-flame retardants: Kubahiriza amabwiriza, byerekana ibizaza.

Igishushanyo mbonera cya nylon flame retardant formulaire igomba gusuzuma ibintu byihariye bisabwa nibisabwa mugihe uhitamo halogene cyangwa halogen idafite flame retardants. Halogenated flame retardants itanga umusaruro mwinshi ariko igatera ingaruka kubidukikije, mugihe ubundi buryo bwa halogene butangiza ibidukikije ariko busaba umubare munini winyongera. Mugutezimbere uburyo nibikorwa, bikora neza, bitangiza ibidukikije, kandi bikoresha ibikoresho bya flame-retardant nylon birashobora gutezwa imbere kugirango bikemure ibikoresho bya elegitoroniki, ibinyabiziga, imyenda, nizindi nganda.
