Inama ku miterere y'imashini zigabanya umuriro zikoresha polystyrene (HIPS) idafite Halogen
Ibisabwa n'abakiriya: Amagufwa adashobora gushya ku bikoresho by'amashanyarazi, imbaraga z'ingaruka ≥7 kJ/m², igipimo cy'amazi ashongeshejwe (MFI) ≈6 g/iminota 10, imashini zitera umuriro.
1. Sisitemu y'ubushyuhe igabanya umurabyo wa Fosifore na Azote
Uburyo bwo gukora imyitozo ngororamubiri igabanya umurabyo mu kibuno (Imbonerahamwe ya 1)
| Igice | Gupakira (phr) | Ibitekerezo |
| Resin y'ikibuno | 100 | Ibikoresho by'ibanze |
| Ammonium polyphosphate (APP) | 15-20 | Inkomoko ya fosifore |
| Melamine cyanurate (MCA) | 5-10 | Isoko ya azote, ikorana na APP |
| Grafiti yagutse (EG) | 3-5 | Yongera imiterere y'inyuguti |
| Umuti urwanya amazi (PTFE) | 0.3-0.5 | Birinda ibitonyanga byashongeshejwe |
| Ihuza (urugero, HIPS yashyizwemo MAH) | 2-3 | Binoza ikwirakwira ry'ibicuruzwa |
Ibiranga:
- Yageze ku ntegoUL94 V-0binyuze mu miterere y'ibara rya intumescent riva kuri APP/MCA synergy.
- Nta halogen irimo kandi ntirinda ibidukikije, ariko ishobora kugabanya imiterere ya mekanike; ikoranabuhanga rirakenewe.
2. Sisitemu y'icyuma igabanya umuriro wa Hydroxide
Uburyo bwo gukora ikibuno (Imbonerahamwe ya 2)
| Igice | Gupakira (phr) | Ibitekerezo |
| Resin y'ikibuno | 100 | - |
| Hydroxide ya aluminiyumu (ATH) | 40-60 | Icanira umuriro cy'ibanze |
| Hydroxide ya manyeziyumu (MH) | 10-20 | Ikorana na ATH |
| Umuti uhuza Silane (urugero, KH-550) | 1-2 | Binoza ikwirakwira ry'ibinure |
| Umuti woroshye (urugero, SEBS) | 5-8 | Ibyishyura igabanuka ry'imbaraga z'impanuka |
Ibiranga:
- Bisabwa>50% by'ibicuruzwakuri UL94 V-0, ariko byangiza imbaraga n'umuvuduko w'ingufu.
- Bikwiriye gukoreshwa mu gihe hadakoreshejwe umwotsi mwinshi cyangwa hadakoreshejwe uburozi bwinshi (urugero, inzira ya gari ya moshi).
3. Sisitemu yo guhuza Fosifore na Azote (Aluminium Hypophosphite + MCA)
Uburyo bwiza bwo gukora hipps
| Igice | Gupakira (phr) | Imikorere/Inyandiko |
| Ikibuno (cyagize ingaruka nyinshi, urugero, PS-777) | 100 | Ibikoresho by'ibanze (ingaruka ≥5 kJ/m²) |
| Hypophosite ya aluminiyumu (AHP) | 12-15 | Isoko ya fosifore, ubushyuhe buhamye |
| Melamine cyanurate (MCA) | 6-8 | Isoko ya azote, ikorana na AHP |
| SEBS/SBS | 8-10 | Ingufu ikomeye yo gukonjesha ≥7 kJ/m² |
| Amavuta ya soya ya parafini/amavuta ya epoxidized | 1-2 | Ivuta rivamo amavuta, rituma amazi atemba/akwirakwira |
| PTFE | 0.3-0.5 | Umuti urwanya amazi |
| Antioxydant 1010 | 0.2 | Birinda kwangirika |
Ibitekerezo by'ingenzi ku gishushanyo mbonera:
- Guhitamo Resin:
- Koresha amanota ya HIPS afite ingaruka nyinshi (urugero,Chimei PH-888,Taifa PG-33) ifite imbaraga z'ubukana bwa 5–6 kJ/m². SEBS yongera imbaraga zo gukomera.
- Kugenzura uburyo amazi atembera:
- AHP/MCA igabanya MFI; igabanya amavuta yo kwisiga (urugero: parafini y'amazi) cyangwa pulasitiki (urugero: amavuta ya soya yahinduwemo epoxidized).
- Niba ibigo by'imari iciriritse bikomeje kuba bike, ongeramoTPU ya 2–3kunoza urujya n'uruza rw'amazi n'ubukomere.
- Kwemeza uburyo umuriro udashobora guhagarara:
- AHP ishobora kugabanuka kugera kuriIbiro 12iyo bihujwe naIbice 2–3 bya EGkubungabunga UL94 V-0.
- KuriUL94 V-2, gabanya imitwaro igabanya umuriro kugira ngo ushyire imbere ingaruka/amazi.
- Ibipimo byo Gutera Inshinge:
- Ubushyuhe:180–220°C(irinde kwangirika kwa AHP/HIPS).
- Umuvuduko wo gutera inshinge:Hagati-hejurukugira ngo hirindwe ko kuzuza neza.
Imikorere iteganijwe:
| Umutungo | Agaciro k'intego | Igipimo ngenderwaho cy'ibizamini |
| Imbaraga z'ingaruka | ≥7 kJ/m² | ISO 179/1eA |
| Igiciro cy'Imari Iciriritse (200°C/5 kg) | 5–7 g/iminota 10 | ASTM D1238 |
| Kudakomeza umuriro | UL94 V-0 (1.6 mm) | UL94 |
| Imbaraga zo gukurura | ≥25 MPa | ISO 527 |
4. Ubundi buryo bwo gukemura ibibazo
- Uburyo bwo kwitabwaho ku giciro: Simbuza AHP igice ukoreshejefosifore itukura ifite ibice bito (3–5 phr), ariko menya ko ibara ridafite aho ribogamiye (ritukura-umukara).
- Kwemeza: Kora igerageza rito kugira ngo uhuze ingaruka n'ubudahangarwa bw'umuriro mbere yo kunoza amazi.
