Ifomyula ethintela ilangatye ebhekisa kwi-adhesives

Uyilo lwefomyula ethintela ilangatye kwiiglue kufuneka lwenziwe ngokwezifiso ngokusekelwe kuhlobo lwesiseko seglue (njenge-epoxy resin, i-polyurethane, i-acrylic, njl.njl.) kunye neemeko zokusetyenziswa (ezifana nolwakhiwo, izixhobo ze-elektroniki, iimoto, njl.njl.). Apha ngezantsi kukho izinto eziqhelekileyo zefomyula ethintela ilangatye ethintela ilangatye kunye nemisebenzi yazo, equka zombini izisombululo ze-halogenated kunye ne-halogen-free flame retardant.

1. Imigaqo yoYilo lokuQokelelwa kweNkunkuma eNcibilikisayo yeLanga

• Ukusebenza kakuhle okuphezulu: Dibana ne-UL 94 V0 okanye i-V2.
• Ukuhambelana: Isithinteli-mlilo kufuneka sihambelane nezinto ezisisiseko zokuncamathelisa ngaphandle kokuchaphazela ukusebenza kwe-bonding.
• Ubuhlobo kwiNdalo: Beka phambili izinto ezithintela ilangatye ezingenayo i-halogen ukuze zihambelane nemigaqo yokusingqongileyo.
• Ukuqhubekeka: Isithinteli-langatye akufuneki siphazamise inkqubo yokuncamathelisa okanye ukuhambahamba kweglue.

2. Ukwenziwa kwe-Adhesive Retardant Adhesive eHalogenated Flame

Izinto ezithintela ilangatye ezifakwe i-halogenated (umz., ezifakwe i-brominated) ziphazamisa ukusabela kwe-combustion chain ngokukhupha ii-halogen radicals, nto leyo enika ukusebenza kakuhle kwe-flame retardant.

Izixhobo zokuQulunqa:

• Izinto ezisisiseko ezincamathelayo: I-Epoxy resin, i-polyurethane, okanye i-acrylic.
• I-Brominated Flame Retardant: 10–20% (umz., i-decabromodiphenyl ether, i-brominated polystyrene).
• I-Antimony Trioxide (iSynergist): 3–5% (iphucula isiphumo sokungatshisi ilangabi).
• I-plasticizer: 1–3% (iphucula ukuguquguquka).
• Iarhente yokunyanga: Ikhethwe ngokusekelwe kuhlobo lokuncamathelisa (umz., i-amine-based for epoxy resin).
• Isinyibilikisi: Njengoko kufuneka (ilungisa i-viscosity).

Iimpawu:

• Iingenelo: Ukusebenza kakuhle kokurhoxisa ilangabi, ubungakanani obuphantsi bokongeza.
• Iingxaki: Ingavelisa iigesi ezinobuthi ngexesha lokutsha; iinkxalabo zokusingqongileyo.

3. Ukwenziwa kwe-Adhesive Retardant Adhesive engenalo i-Halogen-Flame

Izinto ezithintela ilangatye ezingenayo i-halogen (umz., ezisekwe kwi-phosphorus, ezisekwe kwi-nitrogen, okanye ii-hydroxide ezingaphiliyo) zisebenza ngee-endothermic reactions okanye ukwakheka komaleko okhuselayo, nto leyo enika ukusebenza okungcono kokusingqongileyo.

Izixhobo zokuQulunqa:

• Izinto ezisisiseko ezincamathelayo: I-Epoxy resin, i-polyurethane, okanye i-acrylic.
• Ilangatye eliSekelwe kwiPhosphorus: 10–15% (umz.,i-ammonium polyphosphate APPokanye i-phosphorus ebomvu).
• I-Nitrogen-Based Flame Retardant: 5–10% (umz., i-melamine cyanurate MCA).
• IiHydroxides ezingaphiliyo: 20–30% (umz., i-aluminium hydroxide okanye i-magnesium hydroxide).
• I-plasticizer: 1–3% (iphucula ukuguquguquka).
• Iarhente yokunyanga: Ikhethwe ngokusekelwe kuhlobo lweglu.
• Isinyibilikisi: Njengoko kufuneka (ilungisa i-viscosity).

Iimpawu:

• Iingenelo: Inobuhlobo nokusingqongileyo, akukho kukhutshwa kwegesi enobungozi, ithobela imithetho.
• Iingxaki: Ukusebenza okuphantsi kokurhoxisa ilangabi, ubuninzi bezongezo, kunokuchaphazela iimpawu zoomatshini.

4. Izinto ezibalulekileyo ekufuneka ziqwalaselwe kuYilo loYilo loBuchule

• Ukhetho oluBambelela ilangatye:
  • I-Halogenated: Isebenza kakuhle kakhulu kodwa ibeka umngcipheko kwindalo nakwimpilo.
  • Akukho Halogen: Ayinabungozi kwindalo kodwa ifuna ubungakanani obukhulu.
• Ukuhambelana: Qinisekisa ukuba into ethintela ilangatye ayibangeli ukwahlulwa okanye ukunciphisa ukusebenza kwe-bonding.
• Ukuqhubekeka: Kuphephe ukuphazamiseka kokunyangwa kunye nokuhamba kwamanzi.
• Ukuthobela iNdaloKhetha iindlela ezingenayo i-halogen ukuze zihlangabezane ne-RoHS, i-REACH, njl.

5. Izicelo eziqhelekileyo

• Ulwakhiwo: Izinto zokuvala ezingatshiyo, izinto zokuncamathelisa ezakhiweyo.
• Izixhobo zombane: Izincamathelisi zokuncamathelisa zebhodi yesekethe, izincamathelisi eziqhuba umbane.
• Iimoto: Izincamathelisi zezibane zentloko, izincamathelisi zangaphakathi.

6. Iingcebiso zokuphucula ukwenziwa kwefomyula

• Ukuphucula Ukuthintela Ilangatye:
  • Iintlanganisela ze-synergistic (umz., i-halogen-antimony, i-phosphorus-nitrogen).
  • Izinto ezithintela ilangatye le-nano (umz., i-nano magnesium hydroxide okanye i-nano clay) ukuphucula ukusebenza kakuhle nokunciphisa ubungakanani bezongezo.
• Ukuphucula iiPropati zoomatshini:
  • Ii-Tougheners (umz., i-POE okanye i-EPDM) ukuphucula ukuguquguquka kunye nokumelana neempembelelo.
  • Ukuqinisa izizalisi (umz., ifayibha yeglasi) ukuze komelezwe amandla nokuqina.
• Ukuncitshiswa kweendleko:
  • Lungiselela iireyithingi ezithintela ilangatye ukuze kuncitshiswe ukusetyenziswa xa kuhlangatyezwana neemfuno.
  • Khetha izinto ezingabizi kakhulu (umz., izinto ezithintela umlilo zasekhaya okanye ezixutyiweyo).

7. Iimfuneko zeNdalo kunye neMithetho

• Izinto ezithintela ilangatye ezineHalogenated: Ithintelwe phantsi kweRoHS, REACH, njl.njl.; sebenzisa ngononophelo.
• Izinto ezithintela ilangatye ezingenayo iHalogen: Iyahambelana nemigaqo; indlela eza kwenzeka ngayo kwixesha elizayo.

8. Isishwankathelo

Iifomyula ezincamathelayo ezithintela ilangatye kufuneka ziyilwe ngokusekelwe kwizicelo ezithile kunye neemfuno zomthetho, zikhethe phakathi kweendlela ze-halogen okanye ezingenayo i-halogen. Iifomyula ezithintela ilangatye ...
