Malangizo Opangira Mapangidwe Osagwiritsa Ntchito Lawi a Polystyrene Yopanda Halogen (HIPS)
Zofunikira pa Makasitomala: Ma HIPS oletsa moto m'nyumba zosungiramo zida zamagetsi, mphamvu ya impact ≥7 kJ/m², melt flow index (MFI) ≈6 g/10min, jekeseni.
1. Dongosolo Loletsa Moto la Phosphorus-Nitrogen Synergistic
Kupanga kwa HIPS-Retardant Flame (Table 1)
| Chigawo | Kutsegula (phr) | Ndemanga |
| Utomoni wa m'chiuno | 100 | Zinthu zoyambira |
| Ammonium polyphosphate (APP) | 15-20 | Gwero la phosphorous |
| Melamine cyanurate (MCA) | 5-10 | Gwero la nayitrogeni, limagwirizana ndi APP |
| Grafiti yowonjezereka (EG) | 3-5 | Zimathandizira kupangika kwa char |
| Woletsa kudontha (PTFE) | 0.3-0.5 | Zimaletsa madontho osungunuka |
| Chogwirizanitsa (monga, MAH-grafted HIPS) | 2-3 | Zimathandiza kuti anthu azifalikira |
Mawonekedwe:
- AmakwaniritsaUL94 V-0kudzera mu intumescent char formation kuchokera ku mgwirizano wa APP/MCA.
- Palibe halogen komanso siwononga chilengedwe, koma ikhoza kuchepetsa mphamvu za makina; kukonza bwino kumafunika.
2. Dongosolo Loletsa Moto la Chitsulo cha Hydroxide
Kupanga kwa Ma Hips (Table 2)
| Chigawo | Kutsegula (phr) | Ndemanga |
| Utomoni wa m'chiuno | 100 | - |
| Aluminium hydroxide (ATH) | 40-60 | Choletsa moto chachikulu |
| Magnesium hydroxide (MH) | 10-20 | Zimagwirizana ndi ATH |
| Cholumikizira cha silane (monga, KH-550) | 1-2 | Zimathandiza kuti zinthu zifalikire bwino |
| Toughener (monga, SEBS) | 5-8 | Zimathandizira kutayika kwa mphamvu ya kugunda |
Mawonekedwe:
- Amafuna>50% kukwezaya UL94 V-0, koma imawononga mphamvu ndi kayendedwe kake.
- Yoyenera kugwiritsidwa ntchito pochotsa utsi wambiri/poizoni wambiri (monga, poyendera sitima).
3. Dongosolo Logwirizanitsa Phosphorus-Nitrogen (Aluminium Hypophosphite + MCA)
Kupanga Kwabwino Kwambiri kwa Ma Hips
| Chigawo | Kutsegula (phr) | Ntchito/Zolemba |
| Ma HIPS (omwe ali ndi mphamvu zambiri, mwachitsanzo, PS-777) | 100 | Zipangizo zoyambira (mphamvu ≥5 kJ/m²) |
| Aluminium hypophosphite (AHP) | 12-15 | Gwero la phosphorous, kukhazikika kwa kutentha |
| Melamine cyanurate (MCA) | 6-8 | Gwero la nayitrogeni, limagwirizana ndi AHP |
| SEBS/SBS | 8-10 | Cholimba chofunikira kwambiri pakugunda ≥7 kJ/m² |
| Mafuta a soya opangidwa ndi paraffin/epoxidized | 1-2 | Mafuta odzola, amathandiza kuti madzi aziyenda bwino/asafalikire |
| PTFE | 0.3-0.5 | Woletsa kudontha madzi |
| Antioxidant 1010 | 0.2 | Amaletsa kuwonongeka |
Mfundo Zofunika Zoganizira Pakapangidwe:
- Kusankha Utomoni:
- Gwiritsani ntchito magiredi a HIPS omwe ali ndi mphamvu zambiri (monga,Chimei PH-888,Taifa PG-33) yokhala ndi mphamvu yochokera ku mphamvu ya 5–6 kJ/m². SEBS imawonjezeranso kulimba.
- Kulamulira Kuyenda Bwino:
- AHP/MCA imachepetsa MFI; imachepetsa mafuta odzola (monga paraffin wamadzimadzi) kapena ma plasticizer (monga mafuta a soya osungunuka).
- Ngati MFI ikadali yotsika, onjezeraniTPU ya 2–3 phrkuti apititse patsogolo kuyenda bwino komanso kulimba.
- Kutsimikizira Kubwerera kwa Moto:
- AHP ikhoza kuchepetsedwa kufika paMa phr 12ngati ziphatikizidwa ndi2–3 phr EGkusamalira UL94 V-0.
- KwaUL94 V-2, chepetsani katundu woletsa moto kuti muyambe kuyika patsogolo mphamvu/kuyenda kwa magetsi.
- Magawo Opangira Jakisoni:
- Kutentha:180–220°C(pewani kuwonongeka kwa AHP/HIPS).
- Liwiro la jakisoni:Pakati-pamwambakuti mupewe kudzaza kosakwanira.
Magwiridwe Oyembekezeredwa:
| Katundu | Mtengo Wofunika | Muyezo Woyesera |
| Mphamvu ya mphamvu | ≥7 kJ/m² | ISO 179/1eA |
| MFI (200°C/5 kg) | 5–7 g/mphindi 10 | ASTM D1238 |
| Kulephera kwa moto | UL94 V-0 (1.6 mm) | UL94 |
| Kulimba kwamakokedwe | ≥25 MPa | ISO 527 |
4. Mayankho Ena
- Njira Yoyenera Kutengera Mtengo: Sinthani AHP pang'ono ndiphosphorous wofiira wopangidwa ndi microcapsulated (3–5 phr), koma onani malire a mtundu (wofiira-bulauni).
- KutsimikiziraChitani mayeso ang'onoang'ono kuti muyese mphamvu poyerekeza ndi kuchedwa kwa moto musanagwiritse ntchito bwino mphamvu ya magetsi.
