Ngā Tohutohu Hoahoa Hanganga Ārai-Mumura mō te Polystyrene Pānga-Tiketike Kore-Halogen (HIPS)
Ngā Whakaritenga a te KaihokoKo te HIPS ātete-mura mō ngā whare taputapu hiko, te kaha pānga ≥7 kJ/m², te taupū rere rewa (MFI) ≈6 g/10min, te whakahāngai werohanga.
1. Pūnaha Ārai-Mumura Whakakotahi Phosphorus-Hauota
Te Hanganga Ārai-Mumura o HIPS (Ripanga 1)
| Wāhanga | Utaina ana (phr) | Ngā Kōrero |
| te kapia o te hope | 100 | Rauemi turanga |
| Haukinia polyphosphate (APP) | 15-20 | Pūtake Whero |
| Melamine cyanurate (MCA) | 5-10 | Pūtake hauota, e mahi tahi ana me te APP |
| Karāpeti whakawhanui (EG) | 3-5 | Whakarei ake i te hanganga o te waro |
| Ārai-maturuturu (PTFE) | 0.3-0.5 | Ārai i ngā pata rewa |
| Kaiwhakaōrite (hei tauira, HIPS kua tāpirihia ki te MAH) | 2-3 | Whakapai ake i te horapa |
Ngā Āhuatanga:
- WhakatutukiUL94 V-0mā te hanganga āhua intumescent mai i te mahi tahi a APP/MCA.
- Kāore he halogen, he hoa hoki ki te taiao, engari ka whakaitihia pea ngā āhuatanga ā-pūkaha; me arotau.
2. Pūnaha Ārai-Mumura Waikawa Whakarewa
Te Hanganga o te HIPS (Ripanga 2)
| Wāhanga | Utaina ana (phr) | Ngā Kōrero |
| te kapia o te hope | 100 | - |
| Waikawa konumohe (ATH) | 40-60 | Ārai mura tuatahi |
| Waikawa konupūmā (MH) | 10-20 | Ka mahi tahi me ATH |
| Kaihoko hononga silane (hei tauira, KH-550) | 1-2 | Whakapai ake i te horapa o te whakakī |
| Kaiwhakapakari (hei tauira, SEBS) | 5-8 | Hei utu mō te ngaronga o te kaha pānga |
Ngā Āhuatanga:
- Me whai>50% te utainamō UL94 V-0, engari ka whakaiti i te kaha me te rere o te pānga.
- He pai mō ngā mahi iti-paowa/iti-paitini (hei tauira, te tereina).
3. Pūnaha Hononga Phosphorus-Haitore (Hypophosphite Konumohe + MCA)
Te Hanganga HIPS Arotau
| Wāhanga | Utaina ana (phr) | Mahi/Tuhipoka |
| HIPS (te taumata pānga nui, hei tauira, PS-777) | 100 | Rauemi turanga (pānga ≥5 kJ/m²) |
| Konumohe hypophosphate (AHP) | 12-15 | Pūtake whākawa, pumau wera |
| Melamine cyanurate (MCA) | 6-8 | Pūtake hauota, e mahi tahi ana me te AHP |
| SEBS/SBS | 8-10 | Whakapakari nui mō te pānga ≥7 kJ/m² |
| Parafini wai/hinu pīni soya kua whakapūkaratia | 1-2 | He hinu whakahinuhinu, he whakapai ake i te rere/te marara |
| PTFE | 0.3-0.5 | Ārai-maturuturu |
| Ārai mate 1010 | 0.2 | Ārai i te pirau |
Ngā Whakaaro Matua mō te Hoahoa:
- Kōwhiringa Resin:
- Whakamahia ngā taumata HIPS pānga nui (hei tauira,Chimei PH-888,Taifa PG-33) me te kaha pānga ā-roto o te 5–6 kJ/m². Ka whakarei ake a SEBS i te pakari.
- Mana Whakahaere Rere:
- Ka whakaitihia e te AHP/MCA te MFI; ka whakakapia ki ngā hinu whakahinuhinu (hei tauira, te paraffin wai) me ngā mea whakapūmau kirihou (hei tauira, te hinu pīni soya kua whakapūmautia).
- Mena kei te iti tonu te MFI, tāpirihia2–3 phr TPUhei whakapai ake i te rere me te pakari.
- Whakamanatanga Ārai Mura:
- Ka taea te whakaiti i te AHP ki12 ngā haoramēnā ka honoa ki2–3 phr EGhei pupuri i te UL94 V-0.
- MōUL94 V-2, whakaitihia ngā kawenga ātete mura hei whakarite i te pānga/rere.
- Ngā Tawhā Whakarewa Werohanga:
- Te pāmahana:180–220°C(ārai i te whakahekenga o te AHP/HIPS).
- Tere werohanga:Waenga-teiteihei ārai i te whakakī kāore i oti.
Te Mahi e Tumanakohia ana:
| Taonga | Uara Whāinga | Paerewa Whakamātautau |
| Te kaha o te pānga | ≥7 kJ/m² | ISO 179/1eA |
| MFI (200°C/5 kg) | 5–7 karamu/10 meneti | ASTM D1238 |
| Te ātete mura | UL94 V-0 (1.6 mm) | UL94 |
| Te kaha o te kume | ≥25 MPa | ISO 527 |
4. Ngā Otinga Rerekē
- Kōwhiringa Tairongo-UtuWhakakapia te AHP ki tētahi wāhangate whākawa whero kua whakakīia ki roto i te kāpūkara iti (3–5 phr), engari kia mōhio ki te herenga tae (parauri-whero).
- WhakamanatangaWhakahaerehia ngā whakamātautau iti hei whakataurite i te ātete pānga me te ātete mura i mua i te arotau i te rere.
