Likaroloana:
- E hloka>50% ea ho kenyabakeng sa UL94 V-0, empa e fokotsa matla le phallo ea tshusumetso.
- E loketse lits'ebetso tse nang le mosi o fokolang/chefo e tlase (mohlala, lipalangoang tsa terene).
3. Sistimi ea ho kopanya phosphorus le naetrojene (Aluminium Hypophosphite + MCA)
Tlhahiso e Ntlafalitsoeng ea HIPS
| Karolo | Ho ntse ho jarisoa (phr) | Mosebetsi/Lintlha |
| Maqhubu (sehlopha se nang le tšusumetso e kholo, mohlala, PS-777) | 100 | Thepa ea motheo (tšusumetso ≥5 kJ/m²) |
| Aluminium hypophosphite (AHP) | 12-15 | Mohloli oa phosphorus, botsitso ba mocheso |
| Melamine cyanurate (MCA) | 6-8 | Mohloli oa naetrojene, o sebetsa 'moho le AHP |
| SEBS/SBS | 8-10 | Sethapo se matla sa ho tiisa bakeng sa tshusumetso ≥7 kJ/m² |
| Oli ea soya e metsi e nang le parafini/epoxidized | 1-2 | Setlolo, se ntlafatsa phallo/phallo |
| PTFE | 0.3-0.5 | Moemeli o thibelang ho rotha |
| Antioxidant 1010 | 0.2 | E thibela ho senyeha |
Lintlha tsa Bohlokoa tsa Moralo:
- Khetho ea Resin:
- Sebelisa maemo a HIPS a nang le tšusumetso e kholo (mohlala,Chimei PH-888,Taifa PG-33) ka matla a tlhaho a tshusumetso a 5–6 kJ/m². SEBS e eketsa ho tiea le ho feta.
- Taolo ea Phallo:
- AHP/MCA e fokotsa MFI; e lefella ka mafura (mohlala, parafini e metsi) kapa li-plasticizer (mohlala, oli ea soya e nang le epoxidized).
- Haeba MFI e ntse e le tlase, eketsaTPU ea li-phr tse 2–3ho ntlafatsa phallo le ho tiea ha metsi.
- Netefatso ea ho Fokotsa Lelakabe:
- AHP e ka fokotsoa hoLipuo tse 12haeba e kopantsoe leEG ea 2–3ho hlokomela UL94 V-0.
- Bakeng saUL94 V-2, fokotsa meroalo e thibelang malakabe ho beha pele tšusumetso/phallo.
- Liparamitha tsa ho Enta ka Ente:
- Mocheso:180–220°C(qoba ho senyeha ha AHP/HIPS).
- Lebelo la ente:Bohareng-holimoho thibela ho tlatswa ho sa fellang.
Tshebetso e Lebelletsweng:
| Thepa | Boleng ba Sepheo | Tekanyetso ea Teko |
| Matla a tšusumetso | ≥7 kJ/m² | ISO 179/1eA |
| MFI (200°C/5 kg) | 5–7 g/metsotso e 10 | ASTM D1238 |
| Ho lieha ha lelakabe | UL94 V-0 (1.6 mm) | UL94 |
| Matla a tšepe | ≥25 MPa | ISO 527 |
4. Litharollo tse ling
- Khetho e Bontšang Litšenyehelo: Nka sebaka sa AHP ka karolo e itseng kaFosforasi e khubelu e kentsoeng ka har'a capsule e nyane (3–5 phr), empa hlokomela moedi wa mmala (o mofubedu-o sootho).
- Netefatso: Etsa liteko tse nyane ho leka-lekanya tšusumetso khahlanong le ho lieha ha lelakabe pele o ntlafatsa phallo.
