Mafotokozedwe a flame retardant makonzedwe a zomatira

Kapangidwe ka zomatira kolepheretsa moto kutengera zomatira ziyenera kusinthidwa malinga ndi mtundu wa zomatira (monga epoxy resin, polyurethane, acrylic, etc.) ndi mawonekedwe ogwiritsira ntchito (monga zomangamanga, zamagetsi, magalimoto, ndi zina). M'munsimu muli zigawo zomata zomata zomwe zimalepheretsa kuyatsa moto ndi ntchito zake, zomwe zimaphimba zonse zomwe zili ndi halogenated ndi halogen-free flame retardant solution.

1. Mfundo za Adhesive Flame Retardant Formulation Design

• Kuchita Bwino Kwambiri: Kumanani ndi UL 94 V0 kapena V2.
• Kugwirizana: Choyimitsa moto chikuyenera kukhala chogwirizana ndi zomatira m'munsi popanda kusokoneza magwiridwe antchito.
• Ubwenzi Wachilengedwe: Ikani patsogolo zoletsa moto za halogen kuti zigwirizane ndi malamulo a chilengedwe.
• Kuthekera: Chowotcha moto sichiyenera kusokoneza njira yochiritsira yomatira kapena kuyenda.

2. Halogenated Flame Retardant Adhesive Formulation

Ma halogenated flame retardants (mwachitsanzo, brominated) amasokoneza kuyaka kwa tcheni potulutsa ma halogen radicals, kupereka mphamvu yoletsa moto kwambiri.

Zopangira Zopanga:

• Zomatira Base Material: Epoxy resin, polyurethane, kapena acrylic.
• Brominated Flame Retardant: 10-20% (mwachitsanzo, decabromodiphenyl ether, brominated polystyrene).
• Antimony Trioxide (Synergist): 3-5% (imapangitsa kuti moto usawonongeke).
• Plasticizer: 1-3% (imasintha kusinthasintha).
• Wothandizira Wochiritsa: Zosankhidwa potengera zomatira (mwachitsanzo, amine-based for epoxy resin).
• Zosungunulira: Monga pakufunika (kusintha mamasukidwe akayendedwe).

Makhalidwe:

• Ubwino wake: Kugwiritsa ntchito bwino kwamoto woyaka, kutsika kowonjezera.
• Zoipa: Itha kutulutsa mpweya wapoizoni pakuyaka; nkhawa zachilengedwe.

3. Kupanga Zomatira Zopanda Moto za Halogen

Zoletsa moto zopanda halogen (monga phosphorous-based, nitrogen-based, or inorganic hydroxides) zimagwira ntchito popanga ma endothermic kapena kupanga masanjidwe oteteza, zomwe zimapangitsa kuti chilengedwe chiziyenda bwino.

Zopangira Zopanga:

• Zomatira Base Material: Epoxy resin, polyurethane, kapena acrylic.
• Phosphorus-Based Flame Retardant10-15% (mwachitsanzo,ammonium polyphosphate APPkapena phosphorous wofiira).
• Nayitrogeni-Based Flame Retardant: 5-10% (mwachitsanzo, melamine cyanrate MCA).
• Inorganic hydroxides20-30% (mwachitsanzo, aluminium hydroxide kapena magnesium hydroxide).
• Plasticizer: 1-3% (imasintha kusinthasintha).
• Wothandizira Wochiritsa: Osankhidwa potengera mtundu womatira.
• Zosungunulira: Monga pakufunika (kusintha mamasukidwe akayendedwe).

Makhalidwe:

• Ubwino wake: Ndiokonda zachilengedwe, osatulutsa mpweya wapoizoni, wotsatira malamulo.
• Zoipa: Kuchepetsa mphamvu yochepetsera moto, kuchuluka kwa zowonjezera, kungakhudze makina.

4. Mfundo zazikuluzikulu pakupanga mapangidwe

• Kusankhidwa kwa Flame Retardant:
  • Halogenated: Kuchita bwino kwambiri koma kumadzetsa zoopsa zachilengedwe komanso thanzi.
  • Halogen-Free: Eco-friendly koma imafuna kuchuluka kwakukulu.
• Kugwirizana: Onetsetsani kuti chowotcha moto sichimayambitsa delamination kapena kuchepetsa magwiridwe antchito.
• KuthekeraPewani kusokoneza machiritso ndi kuyenda.
• Kutsatira Zachilengedwe: Kukonda zosankha zopanda halogen kuti mukumane ndi RoHS, REACH, ndi zina.

5. Zomwe Zimagwira Ntchito

• Zomangamanga: Zosindikizira zosagwira moto, zomatira zamapangidwe.
• Zamagetsi: Circuit board encapsulation zomatira, zomatira conductive.
• Zagalimoto: Zomatira pamutu, zomatira mkati.

6. Malangizo Okonzekera Kukonzekera

• Kupititsa patsogolo Kuwonongeka kwa Flame:
  • Kuphatikiza kwa synergistic (mwachitsanzo, halogen-antimony, phosphorous-nitrogen).
  • Nano retardants (mwachitsanzo, nano magnesium hydroxide kapena nano dongo) kuti apititse patsogolo mphamvu ndikuchepetsa zowonjezera.
• Kupititsa patsogolo Katundu Wamakina:
  • Tougheners (mwachitsanzo, POE kapena EPDM) kuti apititse patsogolo kusinthasintha komanso kukana mphamvu.
  • Kulimbitsa zodzaza (mwachitsanzo, ulusi wagalasi) kuti muwonjezere mphamvu ndi kusasunthika.
• Kuchepetsa Mtengo:
  • Konzani kuchuluka kwa retardant kuti muchepetse kugwiritsa ntchito mukakwaniritsa zofunikira.
  • Sankhani zinthu zotsika mtengo (monga zotsekera m'nyumba kapena zosakanikirana ndi moto).

7. Zofunikira Zachilengedwe ndi Zowongolera

• Ma Halogenated Flame Retardants: Zoletsedwa pansi pa RoHS, REACH, etc.; gwiritsani ntchito mosamala.
• Ma Halogen-Free Flame Retardants: Kugwirizana ndi malamulo; m'tsogolo.

8. Mwachidule

Zomata zoziziritsa kumoto ziyenera kupangidwa kutengera momwe zimagwiritsidwira ntchito komanso zofunikira pakuwongolera, kusankha pakati pa zosankha za halojeni kapena zopanda halogen. Ma halogenated flame retardants amapereka mphamvu zambiri koma amawononga chilengedwe, pomwe njira zopanda halogen ndizothandiza zachilengedwe koma zimafunikira zowonjezera zambiri. Mwa kukhathamiritsa mapangidwe ndi njira, zomatira zogwira ntchito kwambiri, zokondera zachilengedwe, komanso zotsika mtengo zomangira moto zimatha kupangidwa pomanga, zamagetsi, zamagalimoto, ndi mafakitale ena.
