Nā Manaʻo Manaʻo Hoʻolālā ʻAla ʻAi ʻAi no ka Halogen-Free High-Impact Polystyrene (HIPS)
Pono nā mea kūʻai aku: HIPS pale ahi no nā hale mea uila, ikaika hopena ≥7 kJ/m², melt flow index (MFI) ≈6 g/10min, hoʻoheheʻe ʻia.
1. Phosphorus-Nitrogen Synergistic Flame-Retardant System
HIPS Hoʻolāʻau ʻAi ʻAi Paʻa (Paʻa 1)
| ʻāpana | Ke hoʻouka nei (phr) | ʻŌlelo |
| HIPS resin | 100 | Mea kumu |
| Ammonium polyphosphate (APP) | 15-20 | Puna o ka phosphorus |
| Melamine cyanurate (MCA) | 5-10 | ʻO ke kumu Nitrogen, hui pū me APP |
| graphite i hoʻonui ʻia (EG) | 3-5 | Hoʻonui i ka hana char |
| ʻAi hoʻoheheʻe wai (PTFE) | 0.3-0.5 | Kāohi i nā kulu hehee |
| Mea hoʻohālikelike (e laʻa, HIPS i kālai ʻia ʻo MAH) | 2-3 | Hoʻomaikaʻi i ka hoʻopuehu |
Nā hiʻohiʻona:
- LoaʻaUL94 V-0ma o ka hoʻokumu ʻana i nā char intumescent mai APP/MCA synergy.
- ʻAʻohe halogen a me ka ʻoluʻolu, akā hiki ke hōʻemi i nā waiwai mechanical; pono ka hoʻonui ʻana.
2. Pūnaehana Hoʻopaʻa ʻAi ʻAi ʻAi Metala
Hoʻokumu ʻia ʻo HIPS (Pakaukau 2)
| ʻāpana | Ke hoʻouka nei (phr) | ʻŌlelo |
| HIPS resin | 100 | - |
| Aluminum hydroxide (ATH) | 40-60 | Pākuʻi ahi mua |
| ʻO ka Magnesium hydroxide (MH) | 10-20 | Hoʻohui pū me ATH |
| ʻAno hoʻohui Silane (e laʻa, KH-550) | 1-2 | Hoʻomaikaʻi i ka hoʻopuehu filler |
| Mea paʻakikī (e laʻa, SEBS) | 5-8 | Hoʻopaʻi no ka nalowale o ka ikaika hopena |
Nā hiʻohiʻona:
- Pono>50% hoouka anano UL94 V-0, akā hoʻohaʻahaʻa i ka ikaika a me ke kahe.
- He kūpono no nā noi haʻahaʻa-uwahi/haʻahaʻa-ʻawaʻawa (e laʻa, kaʻaahi kaʻaahi).
3. Pūnaehana Synergistic Phosphorus-Nitrogen (Aluminum Hypophosphite + MCA)
Hoʻolālā ʻia ʻo HIPS
| ʻāpana | Ke hoʻouka nei (phr) | Hana/Memo |
| HIPS (papa hopena kiʻekiʻe, e laʻa, PS-777) | 100 | Mea kumu (ka hopena ≥5 kJ/m²) |
| Aluminum hypophosphite (AHP) | 12-15 | Puna phosphorus, paʻa wela |
| Melamine cyanurate (MCA) | 6-8 | ʻO ke kumu Nitrogen, hui pū me AHP |
| SEBS/SBS | 8-10 | Mea paʻakikī koʻikoʻi no ka hopena ≥7 kJ/m² |
| ʻO ka ʻaila paraffin wai/epoxidized soybean | 1-2 | Lubricant, hoʻomaikaʻi i ke kahe / dispersion |
| PTFE | 0.3-0.5 | ʻAi kūʻokoʻa |
| ʻAiʻona 1010 | 0.2 | Kāohi i ka hoʻohaʻahaʻa |
Nā Manaʻo Hoʻolālā Nui:
- Koho Resin:
- E hoʻohana i nā māka HIPS hopena kiʻekiʻe (e laʻa,Chimei PH-888,Taifa PG-33) me ka ikaika o ka hopena o 5–6 kJ/m². Hoʻonui hou ka SEBS i ka paʻakikī.
- Mana Hoʻoheheʻe:
- Hoʻemi ʻo AHP/MCA i ka MFI; e hoʻopaʻi me nā lubricants (e laʻa, ka paraffin wai) a i ʻole nā mea plasticizers (eg, epoxidized soybean oil).
- Inā haʻahaʻa ka MFI, hoʻohui2–3 hola TPUe hoʻomaikaʻi i ke kahe a me ka paʻakikī.
- Hōʻoiaʻiʻo ʻana i ke ahi:
- Hiki ke hoemi ia AHP i12 phrina hui pu me2–3 phr EGe mālama i ka UL94 V-0.
- No ka meaUL94 V-2, e ho'ēmi i ka hoʻouka ʻana o ke ahi e hoʻokahua i ka hopena/kahe.
- Nā ʻāpana hoʻoheheʻe ʻia:
- Mahana:180–220°C(ʻalo i ka hōʻino ʻana o AHP/HIPS).
- ʻO ka wikiwiki hoʻoheheʻe:Kūwaena-kiʻekiʻee pale i ka hoʻopiha piha ʻole.
Hana i manaʻo ʻia:
| Waiwai | Waiwai Kuhikuhi | Kūlana hoʻāʻo |
| Ka ikaika pili | ≥7 kJ/m² | ISO 179/1eA |
| MFI (200°C/5 kg) | 5–7 g/10min | ASTM D1238 |
| Hoʻopaʻa ahi | UL94 V-0 (1.6 mm) | UL94 |
| Ka ikaika tensile | ≥25 MPa | ISO 527 |
4. Nā Hoʻoponopono ʻē aʻe
- Koho-Kinaki Koho: Hoʻololi hapa AHP memicroencapsulated ʻulaʻula phosphorus (3-5 phr), akā e hoʻomaopopo i ka palena kala (ʻulaʻula-ʻulaʻula).
- Hōʻoia: E hana i nā hoʻāʻo liʻiliʻi e kaulike i ka hopena me ka hoʻopaneʻe ahi ma mua o ka hoʻomaikaʻi ʻana i ke kahe.
