Shawarwarin Tsarin Tsarin Rubuce-rubuce Masu Hana Wuta Don Polystyrene Mai Haɗari Mai Haɗari Ba Tare Da Halogen Ba (HIPS)
Bukatun Abokin Ciniki: HIPS mai hana harshen wuta don gidajen kayan lantarki, ƙarfin tasiri ≥7 kJ/m², ma'aunin kwararar narkewa (MFI) ≈6 g/minti 10, ƙera allura.
1. Tsarin Haɗakar da ke Hana Wutar Lantarki ta Phosphorus-Nitrogen
Tsarin HIPS Mai Rage Wuta (Tebur 1)
| Bangaren | Ana lodawa (phr) | Bayani |
| Resin HIPS | 100 | Kayan tushe |
| Ammonium polyphosphate (APP) | 15-20 | Tushen phosphorus |
| Melamine cyanurate (MCA) | 5-10 | Tushen Nitrogen, yana haɗuwa da APP |
| Faɗaɗa graphite (EG) | 3-5 | Yana inganta tsarin characteristic |
| Maganin hana ɗigawa (PTFE) | 0.3-0.5 | Yana hana ɗigon narkewa |
| Mai jituwa (misali, HIPS da aka haɗa da MAH) | 2-3 | Inganta watsawa |
Siffofi:
- NasarorinUL94 V-0ta hanyar ƙirƙirar char mai ƙarfi daga haɗin gwiwar APP/MCA.
- Ba ya halogen kuma yana da kyau ga muhalli, amma yana iya rage halayen injiniya; ana buƙatar ingantawa.
2. Tsarin hana harshen wuta na ƙarfe Hydroxide
Tsarin HIPS (Tebur 2)
| Bangaren | Ana lodawa (phr) | Bayani |
| Resin HIPS | 100 | - |
| Aluminum hydroxide (ATH) | 40-60 | Babban mai hana harshen wuta |
| Magnesium hydroxide (MH) | 10-20 | Yana aiki tare da ATH |
| Maganin haɗin Silane (misali, KH-550) | 1-2 | Yana inganta watsawar cikawa |
| Mai tauri (misali, SEBS) | 5-8 | Yana rama asarar ƙarfin tasiri |
Siffofi:
- Yana buƙatar>50% lodawadon UL94 V-0, amma yana rage ƙarfin tasiri da kwararar ruwa.
- Ya dace da aikace-aikacen ƙarancin hayaƙi/rashin guba (misali, jigilar jirgin ƙasa).
3. Tsarin Haɗin Phosphorus-Nitrogen (Aluminum Hypophosphite + MCA)
Tsarin HIPS da aka Inganta
| Bangaren | Ana lodawa (phr) | Aiki/Bayanan kula |
| HIPS (matsayin tasiri mai girma, misali, PS-777) | 100 | Tushen abu (tasirin ≥5 kJ/m²) |
| Aluminum hypophosphite (AHP) | 12-15 | Tushen phosphorus, kwanciyar hankali na zafi |
| Melamine cyanurate (MCA) | 6-8 | Tushen Nitrogen, yana haɗuwa da AHP |
| SEBS/SBS | 8-10 | Mahimmin mai tauri don tasiri ≥7 kJ/m² |
| Man waken soya mai ruwa-ruwa/mai mai sinadarin epoxidized | 1-2 | Man shafawa, yana inganta kwarara/watsawa |
| PTFE | 0.3-0.5 | Maganin hana digawa |
| Maganin hana tsufa 1010 | 0.2 | Yana hana lalacewa |
Muhimman Abubuwan Da Za A Yi La'akari da Su:
- Zaɓin Resin:
- Yi amfani da makin HIPS mai tasiri sosai (misali,Chimei PH-888,Taifa PG-33) tare da ƙarfin tasirin da ke cikinsa na 5-6 kJ/m². SEBS yana ƙara haɓaka tauri.
- Sarrafa Gudawa:
- AHP/MCA suna rage MFI; suna ramawa da man shafawa (misali, paraffin na ruwa) ko kuma masu amfani da robobi (misali, man waken soya da aka yi da epoxidized).
- Idan MFI ya kasance ƙasa, ƙaraTPU na 2-3 na safedon inganta kwarara da tauri.
- Tabbatar da Jinkirin Wuta:
- Ana iya rage AHP zuwa12 phridan aka haɗa da2–3 phr EGdon kula da UL94 V-0.
- DominUL94 V-2, rage lodin da ke hana harshen wuta don fifita tasirin/zubar da shi.
- Sigogi na Molding Allura:
- Zafin jiki:180–220°C(ku guji lalata AHP/HIPS).
- Saurin allura:Matsakaici-tsayidon hana cikawa ba tare da cikakke ba.
Aikin da ake tsammani:
| Kadara | Darajar Manufa | Tsarin Gwaji |
| Ƙarfin tasiri | ≥7 kJ/m² | ISO 179/1eA |
| MFI (200°C/5 kg) | 5–7 g/minti 10 | ASTM D1238 |
| Rashin ƙarfin harshen wuta | UL94 V-0 (1.6 mm) | UL94 |
| Ƙarfin tauri | ≥25 MPa | ISO 527 |
4. Madadin Mafita
- Zaɓin Mai Sauƙin Kula da Farashi: Sauya AHP kaɗan dajan phosphorus mai ƙarancin ƙarfi (3-5 hr), amma a lura da iyakancewar launi (ja-launin ruwan kasa).
- Tabbatarwa: Gudanar da ƙananan gwaje-gwaje don daidaita tasirin da kuma jinkirin wuta kafin inganta kwararar ruwa.
