Isalathiso sokwenziwa kwe-retardant ye-flame for adhesives

Uyilo lwento yokuncamathelisa i-flame retardant ye-adhesives kufuneka yenziwe ngokwezifiso ngokusekelwe kuhlobo lwesiseko se-adhesive (efana ne-epoxy resin, i-polyurethane, i-acrylic, njl.) kunye neemeko zesicelo (ezifana nokwakhiwa, i-electronics, i-automotive, njl. Apha ngezantsi kukho amacandelo aqhelekileyo ancamathelayo elangatye lokubuyiswa komlilo kunye nemisebenzi yawo, egubungela zombini izisombululo ze-halogenated kunye ne-halogen-free flame retardant.

1. Imigaqo ye-Adhesive Flame Retardant Formulation Design

• Ukusebenza okuphezulu: Dibana ne-UL 94 V0 okanye iV2.
• Ukuhambelana: I-flame retardant kufuneka ihambelane nesiseko se-adhesive material ngaphandle kokuchaphazela ukusebenza kokubambisana.
• Ubuhlobo bendalo: Beka phambili iiretadanti zedangatye ezingenalo halogen ukuze zithobele imigaqo yokusingqongileyo.
• Ukuqhubekeka: I-flame retardant akufanele iphazamise inkqubo yokunyathela ye-adhesive okanye ukuhamba.

2. I-Halogenated Flame Retardant Adhesive Formulation

I-halogenated flame retardants (umz., brominated) iphazamisa ukutsha kwetsheyini lokutsha ngokukhupha i-halogen radicals, enika ukusebenza kakuhle kokubuyiswa komlilo.

Amacandelo okuqulunqa:

• I-Adhesive Base Material: I-epoxy resin, i-polyurethane, okanye i-acrylic.
• I-Brominated Flame Retardant: 10-20% (umzekelo, i-decabromodiphenyl ether, i-brominated polystyrene).
• IAntimony Trioxide (Synergist): I-3-5% (iphucula isiphumo somlilo we-flame retardant).
• Iplastiki: 1-3% (iphucula ukuguquguquka).
• Iarhente yokunyanga: Ikhethwe ngokusekelwe kuhlobo lokunamathela (umzekelo, i-amine-based for epoxy resin).
• Isinyibilikisi: Njengoko kufuneka (ilungisa i-viscosity).

Iimpawu:

• Iingenelo: Ukusebenza kakuhle kwe-flame retardant, inani eliphantsi lokongezwa.
• Iingxaki: Inokuvelisa iigesi ezinetyhefu ngexesha lokutsha; iinkxalabo zokusingqongileyo.

3. I-Halogen-Free Flame Retardant Adhesive Formulation

I-halogen-free flame retardants (umzekelo, i-phosphorus-based, i-nitrogen-based, okanye i-inorganic hydroxides) isebenza ngokusabela kwe-endothermic okanye ukwakheka komalale okhuselayo, okunika ukusebenza okungcono kokusingqongileyo.

Amacandelo okuqulunqa:

• I-Adhesive Base Material: I-epoxy resin, i-polyurethane, okanye i-acrylic.
• I-Phosphorus-Based Flame Retardant: 10–15% (umz.,ammonium polyphosphate APPokanye i-phosphorus ebomvu).
• I-Nitrogen-Based Flame Retardant: 5-10% (umzekelo, i-melamine cyanrate MCA).
• I-Inorganic Hydroxides: 20-30% (umzekelo, i-aluminium hydroxide okanye i-magnesium hydroxide).
• Iplastiki: 1-3% (iphucula ukuguquguquka).
• Iarhente yokunyanga: Ikhethwe ngokusekelwe kuhlobo lokunamathela.
• Isinyibilikisi: Njengoko kufuneka (ilungisa i-viscosity).

Iimpawu:

• Iingenelo: Ubuhlobo bendalo, akukho kukhutshwa kwegesi eyityhefu, ehambelana nemimiselo.
• Iingxaki: Ukusebenza okuphantsi kwe-flame retardant, izixa eziphezulu zokongeza, kunokuchaphazela iipropati zoomatshini.

4. Iingqwalasela ezingundoqo kuYilo loYilo

• UKhetho lwe-Flame Retardant:
  • I-Halogenated: Ukusebenza okuphezulu kodwa kubangela ingozi yendalo kunye nempilo.
  • IHalogen-Isimahla: I-Eco-friendly kodwa ifuna izixa ezikhulu.
• Ukuhambelana: Qinisekisa ukuba i-flame retardant ayibangeli ukuchithwa okanye ukunciphisa ukusebenza kwebhondi.
• Ukuqhubekeka: Kuphephe ukuphazamisana nokunyanga nokuhamba.
• Ukuthotyelwa kokusiNgqongileyo: Khetha iinketho ezingenazo i-halogen ukuhlangabezana ne-RoHS, REACH, njl.

5. Izicelo eziqhelekileyo

• Ukwakhiwa: Izitywini ezimelana nomlilo, izinto zokuncamathelisa zesakhiwo.
• Electronics: Ibhodi yesekethe ye-encapsulation adhesives, i-adhesive conductive.
• Iimoto: Ukunamathiswa kwe-headlight, ukunamathela kwangaphakathi.

6. Iingcebiso zokuPhuculwa koKuqulunqwa

• Ukuphucula ukuKhawuleza koMbane:
  • Ukuhlanganiswa kwe-Synergistic (umzekelo, i-halogen-antimony, i-phosphorus-nitrogen).
  • I-Nano flame retardants (umzekelo, i-nano magnesium hydroxide okanye i-nano clay) ukuphucula ukusebenza kakuhle kunye nokunciphisa inani elongezelelweyo.
• Ukuphuculwa kweePropati zoomatshini:
  • I-Tougheners (umzekelo, i-POE okanye i-EPDM) ukwandisa ukuguquguquka kunye nokuchasana kwempembelelo.
  • Ukuqinisa izihluzi (umzekelo, i-fiber yeglasi) ukwandisa amandla kunye nokuqina.
• UkuNcitshiswa kweendleko:
  • Lungiselela umlinganiselo wokubuyiswa komlilo ukuze unciphise ukusetyenziswa ngelixa uhlangabezana neemfuno.
  • Khetha izinto ezingabizi kakhulu (umzekelo, iiretardants zasekhaya okanye ezidityanisiweyo).

7. IiMfuno zokusiNgqongileyo nezoLawulo

• IHalogenated Flame Retardants: Ithintelwe phantsi kwe-RoHS, REACH, njl.; sebenzisa ngononophelo.
• IHalogen-Free Flame Retardants: Ukuthobela imigaqo; indlela yexesha elizayo.

8. Isishwankathelo

Ukwakhiwa kwe-Adhesive flame retardant kufuneka kuyilwe ngokusekelwe kwizicelo ezithile kunye neemfuno zokulawula, ukukhetha phakathi kwe-halogenated okanye i-halogen-free options. I-halogenated flame retardants ibonelela ngokusebenza okuphezulu kodwa ibeka imingcipheko yokusingqongileyo, ngelixa ezinye iindlela ezingenazo i-halogen zinobuhlobo nendalo kodwa zifuna izixa eziphezulu zokongeza. Ngokulungisa imiqulu kunye neenkqubo, ukusebenza okuphezulu, ukulungelelana kokusingqongileyo, kunye neendleko ezisebenzayo zokuncamathelisa i-flame retardant zinokuphuhliselwa ukwakhiwa, i-electronics, i-automotive, kunye namanye amashishini.
