Ukwakhiwa kwereferensi ye-flame retardant yama-adhesives

Idizayini yokubunjwa kwe-flame retardant yezinto ezinamathelayo idinga ukwenziwa ngendlela oyifisayo ngokusekelwe ohlotsheni lwesisekelo sokunamathelayo (njenge-epoxy resin, i-polyurethane, i-acrylic, njll.) kanye nezimo zokusetshenziswa (njengokwakha, izinto zikagesi, ezezimoto, njll.). Ngezansi kukhona izakhi ezivamile zokuhlanganisa i-adhesive flame retardant kanye nemisebenzi yazo, ehlanganisa kokubili izixazululo ze-halogenated ne-halogen-free flame retardant.

1. Izimiso Zomklamo Wokwakhiwa Kwe-Adhesive Flame Retardant

• Ukusebenza Okuphezulu: Hlangana ne-UL 94 V0 noma i-V2.
• Ukuhambisana: I-flame retardant kufanele ihambisane nesisekelo sokunamathela ngaphandle kokuthinta ukusebenza kokubopha.
• Ubungane Bemvelo: Beka kuqala izinciphisi zamalangabi ezingenalo i-halogen ukuze zihambisane nemithetho yemvelo.
• Ukusebenziseka: I-flame retardant akufanele iphazamise inqubo ye-adhesive yokuphulukisa noma ukugeleza.

2. I-Halogenated Flame Retardant Adhesive Formulation

Ama-halogenated flame retardants (isb., brominated) aphazamisa ukusabela kweketango lomlilo ngokukhulula ama-halogen radicals, anikeza ukusebenza kahle kwe-flame retardant.

Izingxenye Zokwakha:

• I-Adhesive Base MaterialI-Epoxy resin, i-polyurethane, noma i-acrylic.
• I-Brominated Flame Retardant: 10–20% (isb, i-decabromodiphenyl ether, i-brominated polystyrene).
• I-Antimony Trioxide (Synergist): 3–5% (ithuthukisa umphumela wokunqanda ilangabi).
• I-Plasticizer: 1–3% (ithuthukisa ukuguquguquka).
• I-ejenti yokwelapha: Kukhethwe ngokusekelwe ohlotsheni lwe-adhesive (isb, i-amine-based for epoxy resin).
• I-solvent: Njengoba kudingeka (ilungisa i-viscosity).

Izici:

• Izinzuzo: Ukusebenza kahle kwe-flame retardant, inani eliphansi lesengezo.
• Ukubi: Ingase ikhiqize amagesi anobuthi ngesikhathi sokusha; ukukhathazeka kwemvelo.

3. I-Halogen-Free Flame Adhesive Adhesive Formation

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.

Izingxenye Zokwakha:

• I-Adhesive Base MaterialI-Epoxy resin, i-polyurethane, noma i-acrylic.
• I-Phosphorus-Based Flame Retardant: 10–15% (isb.ammonium polyphosphate APPnoma i-phosphorus ebomvu).
• I-Nitrogen-Based Flame Retardant: 5–10% (isb, i-melamine cyanrate MCA).
• I-Inorganic Hydoxide: 20-30% (isb, i-aluminium hydroxide noma i-magnesium hydroxide).
• I-Plasticizer: 1–3% (ithuthukisa ukuguquguquka).
• I-ejenti yokwelapha: Kukhethwe ngokusekelwe kuhlobo lokunamathela.
• I-solvent: Njengoba kudingeka (ilungisa i-viscosity).

Izici:

• Izinzuzo: Ayihambisani nemvelo, akukho kukhishwa kwegesi enobuthi, okuhambisana nemithethonqubo.
• Ukubi: Ukusebenza kahle kokubuyiswa komlilo okuphansi, amanani aphezulu okungezwayo, kungase kuthinte izakhiwo zemishini.

4. Okucatshangelwayo Okubalulekile Emklamweni Wokwakha

• Ukukhetha I-Flame Retardant:
  • I-Halogenated: Ukusebenza okuphezulu kodwa kubangela izingozi zemvelo nempilo.
  • I-Halogen-Free: I-Eco-friendly kodwa idinga amanani amakhulu.
• Ukuhambisana: Qinisekisa ukuthi i-flame retardant ayibangeli ukubola noma yehlise ukusebenza kwebhondi.
• Ukusebenziseka: Gwema ukuphazamisa ekwelapheni kanye nokugeleza.
• Ukuthobela Imvelo: Khetha izinketho ezingenayo i-halogen ukuhlangabezana ne-RoHS, REACH, njll.

5. Izicelo Ezijwayelekile

• Ukwakha: Ama-sealant angashi, izinamathiselo zesakhiwo.
• Ezogesi: Izinamatheliso ze-encapsulation zebhodi lesifunda, ama-adhesive conductive.
• Ezezimoto: Izinamathiselo ze-Headlight, izinamathiselo zangaphakathi.

6. Izincomo Zokuthuthukisa Ukwakhiwa

• Ukuthuthukisa Ukubuyiswa Kwelangabi:
  • Inhlanganisela ye-Synergistic (isb, i-halogen-antimony, i-phosphorus-nitrogen).
  • I-Nano flame retardants (isb, i-nano magnesium hydroxide noma i-nano clay) ukuze kuthuthukiswe ukusebenza kahle nokunciphisa amanani angeziwe.
• Ukuthuthukisa Izakhiwo Zemishini:
  • Ama-Tougheners (isb, i-POE noma i-EPDM) ukuthuthukisa ukuguquguquka nomthelela wokumelana.
  • Ukuqinisa ama-filler (isb, i-glass fiber) ukwandisa amandla nokuqina.
• Ukwehliswa Kwezindleko:
  • Lungiselela izilinganiso ze-flame retardant ukuze unciphise ukusetshenziswa ngenkathi uhlangabezana nezidingo.
  • Khetha izinto ezingabizi kakhulu (isb., ama-flame retardants asekhaya noma ahlanganisiwe).

7. Izidingo Zemvelo Nezokulawula

• Ama-Halogenated Flame Retardants: Ikhawulelwe ngaphansi kwe-RoHS, REACH, njll.; sebenzisa ngokucophelela.
• Ama-Halogen-Free Flame Retardants: Ukuthobela imithethonqubo; umkhuba wesikhathi esizayo.

8. Isifinyezo

Ukwakhiwa kwe-Adhesive flame retardant kufanele kuklanywe ngokusekelwe kuzinhlelo zokusebenza ezithile kanye nezidingo zokulawula, ukukhetha phakathi kwezinketho ze-halogenated noma ezingenayo i-halogen. Ama-halogenated flame retardants anikeza ukusebenza kahle okuphezulu kodwa afaka izingozi zemvelo, kuyilapho ezinye izindlela ezingenazo i-halogen zivumelana nemvelo kodwa zidinga amanani aphezulu okunezelwa. Ngokwenza kahle ukwakheka nezinqubo, izinto zokunamathela ezisebenza kahle kakhulu, ezinobungani nemvelo, nezingabizi kakhulu zingathuthukiswa ukuze kwakhiwe, eze-electronics, ezezimoto, nezinye izimboni.
