Atụmatụ Nhazi Ihe Ndị Na-egbochi Ọkụ Maka Polystyrene Na-enweghị Halogen (HIPS)
Ihe Ndị Ahịa Chọrọ: HIPS nke na-egbochi ire ọkụ maka ebe a na-etinye ngwa eletriki, ike mmetụta ≥7 kJ/m², ndeksi mmiri gbazee (MFI) ≈6 g/10 nkeji, ịkpụzi ihe ntụtụ.
1. Sistemụ Nrụpụta Ọkụ Na-egbochi Phosphorus-Nitrogen
Usoro HIPS nke na-egbochi ire ọkụ (Tebụl 1)
| Akụkụ | Na-ebugo (phr) | Okwu ndị e kwuru |
| Resin HIPS | 100 | Ihe isi ihe |
| Ammonium polyphosphate (APP) | 15-20 | Isi iyi phosphorus |
| Melamine cyanurate (MCA) | 5-10 | Isi iyi nitrogen, na-emekọrịta na APP |
| Grafit gbasaara (EG) | 3-5 | Na-eme ka nhazi àgwà dịkwuo mma |
| Ihe na-egbochi ntapu mmiri (PTFE) | 0.3-0.5 | Na-egbochi ụmụ irighiri mmiri gbazere agbaze |
| Ihe na-eme ka ihe kwekọọ (dịka ọmụmaatụ, HIPS nke e tinyere na MAH) | 2-3 | Na-eme ka mgbasa dịkwuo mma |
atụmatụ:
- MmezuUL94 V-0site na nhazi intumescent char site na mmekorita APP/MCA.
- Enweghị halogen na gburugburu ebe obibi, mana ọ nwere ike ibelata ihe onwunwe igwe; ọ dị mkpa imeziwanye ya.
2. Sistemụ Na-egbochi Ọkụ nke Metal Hydroxide
Usoro HIPS (Tebụl 2)
| Akụkụ | Na-ebugo (phr) | Okwu ndị e kwuru |
| Resin HIPS | 100 | - |
| Aluminom hydroxide (ATH) | Afọ 40-60 | Ihe mgbochi ọkụ bụ isi |
| Magnesium hydroxide (MH) | 10-20 | Na-ejikọta ya na ATH |
| Ihe njikọ Silane (dịka ọmụmaatụ, KH-550) | 1-2 | Na-eme ka mgbasa ihe njupụta ka mma |
| Ihe siri ike (dịka ọmụmaatụ, SEBS) | 5-8 | Na-akwụ ụgwọ maka mfu ike mmetụta |
atụmatụ:
- ChọrọIbu >50%maka UL94 V-0, mana ọ na-emebi ike na mmiri mmetụta.
- Ọ dị mma maka iji obere anwụrụ ọkụ/ihe na-egbu egbu (dịka ọmụmaatụ, ụgbọ okporo ígwè).
3. Sistemụ Njikọ Phosphorus-Nitrogen (Aluminum Hypophosphite + MCA)
Usoro HIPS kachasị mma
| Akụkụ | Na-ebugo (phr) | Ọrụ/Ihe ndetu |
| HIPS (ọkwa mmetụta dị elu, dịka ọmụmaatụ, PS-777) | 100 | Ihe dị n'okpuru (mmetụta ≥5 kJ/m²) |
| Aluminom hypophosphite (AHP) | 12-15 | Isi iyi phosphorus, nkwụsi ike okpomọkụ |
| Melamine cyanurate (MCA) | 6-8 | Isi iyi nitrogen, na-emekọrịta na AHP |
| SEBS/SBS | 8-10 | Ihe siri ike dị mkpa maka mmetụta ≥7 kJ/m² |
| Mmanụ soybean mmiri mmiri paraffin/epoxidized | 1-2 | Mmanụ mmanu, na-eme ka mmiri na-asọ/agbasa nke ọma |
| PTFE | 0.3-0.5 | Ọgwụ mgbochi ntapụ mmiri |
| Ọgwụ mgbochi oxidant 1010 | 0.2 | Na-egbochi mmebi |
Ihe Ndị Dị Mkpa E Ji Mee Nhazi:
- Nhọrọ resin:
- Jiri akara HIPS dị elu (dịka ọmụmaatụ,Chimei PH-888,Taifa PG-33) nwere ike mmetụta sitere n'okike nke 5–6 kJ/m². SEBS na-eme ka ike sie ike dịkwuo elu.
- Njikwa Njem Na-aga n'ihu:
- AHP/MCA na-ebelata MFI; na-eji mmanụ mmanụ (dịka ọmụmaatụ, paraffin mmiri mmiri) ma ọ bụ ihe ndị na-eme ka plastik dị nro (dịka ọmụmaatụ, mmanụ soybean e tinyere na epoxid).
- Ọ bụrụ na MFI anọgide na-adị ala, tinyeTPU 2–3 kwa elekereiji melite mmiri na ike.
- Nnwale Nkwụsị Ọkụ:
- Enwere ike belata AHP ka ọ bụrụ otu12 phrọ bụrụ na ejikọtara ya na2–3 phr EGiji nọgide na-enwe UL94 V-0.
- MakaUL94 V-2, belata ibu ndị na-egbochi ire ọkụ iji mee ka mmetụta/mgbapụta dị mkpa.
- Ọgwụ na ịkpụzi paramita:
- Okpomọkụ:180–220°C(zere mmebi nke AHP/HIPS).
- Ọsọ ịgba ọgwụ:Ọkara-eluiji gbochie ijupụta ihe na-ezughị ezu.
Arụmọrụ a tụrụ anya ya:
| Akụ na ụba | Uru Ebumnuche | Ụkpụrụ Ule |
| Ike mmetụta | ≥7 kJ/m² | ISO 179/1eA |
| MFI (200°C/5 kg) | 5–7 g/nkeji iri | ASTM D1238 |
| Ire ọkụ na-adịghị mma | UL94 V-0 (1.6 mm) | UL94 |
| Ike ọdụdọ | ≥25 MPa | ISO 527 |
4. Ngwọta Ndị Ọzọ
- Nhọrọ Na-emetụta Ọnụ Ego: Dochie AHP n'akụkụ ụfọdụ naphosphorus uhie a gbanyere n'ime obere kapsụl (3–5 phr), mana rịba ama na agba ya dị oke mma (ọ na-acha ọbara ọbara-agba aja aja).
- Nkwenye: Mee obere nnwale iji dozie mmetụta na ire ọkụ tupu ị hazie usoro mmiri.
