Izincomo Zomklamo Wokwakheka Okungashisi Amalangabi we-Polystyrene Enamandla Engenawo i-Halogen (ama-HIPS)
Izidingo Zamakhasimende: Ama-HIPS avimbela ilangabi ezindlini zemishini kagesi, amandla okushaya ≥7 kJ/m², inkomba yokugeleza kokuncibilika (i-MFI) ≈6 g/10min, ukubumba ngomjovo.
1. Uhlelo Lokuvimbela Amalangabi Oluhambisana Ne-Phosphorus-Nitrogen
Ukwakheka Okungalawuli Ilangabe Kwezihlubuki (Ithebula 1)
| Ingxenye | Iyalayisha (phr) | Amazwi |
| I-resin ye-HIPS | 100 | Izinto eziyisisekelo |
| I-Ammonium polyphosphate (APP) | 15-20 | Umthombo we-phosphorus |
| I-Melamine cyanurate (MCA) | 5-10 | Umthombo we-nitrogen, uhambisana ne-APP |
| I-graphite enwetshiwe (EG) | 3-5 | Kuthuthukisa ukwakheka kwezinhlamvu |
| I-ejenti yokulwa nokuconsa (i-PTFE) | 0.3-0.5 | Ivimbela amaconsi ancibilikisiwe |
| I-Compatibilizer (isb., ama-HIPS afakwe ku-MAH) | 2-3 | Kuthuthukisa ukuhlakazeka |
Izici:
- ImpumeleloI-UL94 V-0ngokwakhiwa kwe-intumescent char kusuka ekusebenzisaneni kwe-APP/MCA.
- Ayina-halogen futhi inobungani nemvelo, kodwa inganciphisa izakhiwo zemishini; kudingeka ukulungiswa.
2. Uhlelo Lokuvimbezela Ilangabi Le-Metal Hydroxide
Ukwakhiwa Kwama-HIPS (Ithebula 2)
| Ingxenye | Iyalayisha (phr) | Amazwi |
| I-resin ye-HIPS | 100 | - |
| I-aluminium hydroxide (ATH) | 40-60 | Isivimbeli somlilo esiyinhloko |
| I-Magnesium hydroxide (MH) | 10-20 | Isebenzisana ne-ATH |
| I-ejenti yokuxhuma i-Silane (isb., KH-550) | 1-2 | Kuthuthukisa ukusabalala kokugcwalisa |
| I-Toughener (isb., i-SEBS) | 5-8 | Ibuyisela ukulahleka kwamandla okushaya |
Izici:
- Kudinga>50% ukulayishakwe-UL94 V-0, kodwa kwehlisa amandla omthelela kanye nokugeleza kwawo.
- Ifanele ukusetshenziswa kwentuthu encane/ukungabi nobuthi obuphansi (isb., ukuhamba ngesitimela).
3. Uhlelo lwe-Phosphorus-Nitrogen Synergistic (i-Aluminium Hypophosphite + MCA)
Ukwakheka Kwe-HIPS Okulungiselelwe
| Ingxenye | Iyalayisha (phr) | Umsebenzi/Amanothi |
| Ama-HIPS (izinga elinomthelela omkhulu, isib., i-PS-777) | 100 | Izinto eziyisisekelo (umthelela ≥5 kJ/m²) |
| I-aluminium hypophosphite (AHP) | 12-15 | Umthombo we-phosphorus, ukuzinza kokushisa |
| I-Melamine cyanurate (MCA) | 6-8 | Umthombo we-nitrogen, uhambisana ne-AHP |
| I-SEBS/SBS | 8-10 | Isithambisi esibalulekile sokushaya ≥7 kJ/m² |
| Uwoyela wesoya owuketshezi we-paraffin/epoxidized | 1-2 | Isithambisi, sithuthukisa ukugeleza/ukuhlakazeka |
| I-PTFE | 0.3-0.5 | I-ejenti yokulwa nokuconsa |
| I-Antioxidant 1010 | 0.2 | Kuvimbela ukuwohloka |
Izinto Ezibalulekile Okufanele Uzicabangele Ngokuklama:
- Ukukhethwa kwe-Resin:
- Sebenzisa amazinga e-HIPS anomthelela omkhulu (isb.,I-Chimei PH-888,I-Taifa PG-33) enamandla omthelela angokwemvelo angu-5–6 kJ/m². I-SEBS ithuthukisa ukuqina kwayo.
- Ukulawula Ukugeleza:
- I-AHP/MCA inciphisa i-MFI; ibuyisela ngamafutha okugcoba (isb., i-paraffin ewuketshezi) noma ama-plasticizer (isb., uwoyela wesoya ofakwe i-epoxidized).
- Uma i-MFI ihlala iphansi, engezaI-TPU engama-phr angu-2–3ukuthuthukisa ukugeleza nokuqina.
- Ukuqinisekiswa Kokuvinjelwa Komlilo:
- I-AHP ingancishiswa ibe yi-Izinhlamvu ezingu-12uma kuhlanganiswe2–3 i-EGukugcina i-UL94 V-0.
- NgobaI-UL94 V-2, nciphisa umthwalo ovimbela ilangabi ukuze ubeke phambili umthelela/ukugeleza.
- Amapharamitha Okubumba Umjovo:
- Izinga lokushisa:180–220°C(gwema ukuwohloka kwe-AHP/HIPS).
- Isivinini somjovo:Okuphakathi nendawo okuphezuluukuvimbela ukugcwaliswa okungaphelele.
Ukusebenza Okulindelekile:
| Impahla | Inani Eliqondiwe | Izinga Lokuhlola |
| Amandla omthelela | ≥7 kJ/m² | I-ISO 179/1eA |
| I-MFI (200°C/5 kg) | 5–7 g/10 min | I-ASTM D1238 |
| Ukuphelelwa yilangatye | I-UL94 V-0 (1.6 mm) | UL94 |
| Amandla okudonsa | ≥25 MPa | I-ISO 527 |
4. Izixazululo Ezihlukile
- Inketho Ebucayi Ngezindleko: Faka esikhundleni i-AHP kancane ngei-phosphorus ebomvu efakwe emaphaketheni amancane (3–5 phr), kodwa qaphela ukulinganiselwa kombala (obomvu-onsundu).
- Ukuqinisekiswa: Yenza izivivinyo ezincane ukuze ulinganisele umthelela uma kuqhathaniswa nokuvinjelwa komlilo ngaphambi kokuthuthukisa ukugeleza.
