Mazano ekugadzira Mushonga Unodzivirira Moto wePolystyrene (HIPS) Isina Halogen
Zvinodiwa neVatengi: HIPS inodzivirira moto yedzimba dzemidziyo yemagetsi, simba rekukanganisa ≥7 kJ/m², melt flow index (MFI) ≈6 g/10min, injection molding.
1. Sisitimu Inodzivirira Moto Inodzivirira Phosphorus-Nitrogen
Kugadzirwa kweHIPS-Retardant Flame (Tafura 1)
| Chikamu | Kurodha (phr) | Mashoko |
| Resin yehudyu | 100 | Zvinhu zvepakutanga |
| Ammonium polyphosphate (APP) | 15-20 | Phosphorus inobva |
| Melamine cyanurate (MCA) | 5-10 | Nitrogen inobva, inoshanda pamwe chete neAPP |
| Graphite yakawedzerwa (EG) | 3-5 | Inowedzera kuumbwa kwemavara |
| Mushonga unodzivirira kudonha kwemvura (PTFE) | 0.3-0.5 | Inodzivirira madonhwe akanyungudutswa |
| Compatibilizer (semuenzaniso, MAH-grafted HIPS) | 2-3 | Inovandudza kupararira |
Zvinhu zvirimo:
- AnobudiriraUL94 V-0kuburikidza nekuumbwa kwechar inobuda mukati kubva kuAPP/MCA synergy.
- Haina halogen uye haikuvadzi nharaunda, asi inogona kuderedza hunhu hwemakanika; kugadzirisa kunodiwa.
2. Sisitimu Inodzora Moto yeSimbi Hydroxide
Kuumbwa kweHudyu (Tafura 2)
| Chikamu | Kurodha (phr) | Mashoko |
| Resin yehudyu | 100 | - |
| Aluminium hydroxide (ATH) | 40-60 | Chinhu chinodzora moto chikuru |
| Magnesium hydroxide (MH) | 10-20 | Inoshanda pamwe chete neATH |
| Mushonga wekubatanidza silane (semuenzaniso, KH-550) | 1-2 | Inovandudza kupararira kwezvizere |
| Toughener (semuenzaniso, SEBS) | 5-8 | Inotsiva kurasikirwa nesimba remuchina |
Zvinhu zvirimo:
- Zvinoda>50% kurodhayeUL94 V-0, asi inoderedza simba remagetsi uye kuyerera kwemagetsi.
- Yakakodzera kushandiswa pakushandisa zvinhu zvisina utsi hwakawanda/zvisina chepfu yakawanda (semuenzaniso, kutakura vanhu nechitima).
3. Sisitimu yePhosphorus-Nitrogen Synergistic (Aluminum Hypophosphite + MCA)
Kugadzirwa kweHIPS Kwakagadziridzwa
| Chikamu | Kurodha (phr) | Basa/Zvinyorwa |
| HIPS (mhando yepamusoro, semuenzaniso, PS-777) | 100 | Zvinhu zvepakutanga (kukanganisa ≥5 kJ/m²) |
| Aluminum hypophosphite (AHP) | 12-15 | Phosphorus source, kugadzikana kwekupisa |
| Melamine cyanurate (MCA) | 6-8 | Nitrogen inobva, inoshanda pamwe chete neAHP |
| SEBS/SBS | 8-10 | Chinosimbisa simba rekurova ≥7 kJ/m² |
| Mafuta e soya ane parafini/epoxidized | 1-2 | Mafuta anozora, anovandudza kuyerera/kupararira kwemvura |
| PTFE | 0.3-0.5 | Mushonga unodzivirira kudonha kwemvura |
| Antioxidant 1010 | 0.2 | Inodzivirira kuora |
Zvinhu Zvikuru Zvekufunga Nezvekugadzira:
- Kusarudzwa kweResin:
- Shandisa magiredhi eHIPS ane simba guru (semuenzaniso,Chimei PH-888,Taifa PG-33) ine simba rekusimba re5–6 kJ/m². SEBS inowedzera kusimba kwayo.
- Kudzora Kuyerera Kwemvura:
- AHP/MCA inoderedza MFI; inotsiva nemafuta anonhuhwirira (semuenzaniso, paraffin yemvura) kana mapurasitiki (semuenzaniso, mafuta esoya akasanganiswa ne epoxidized).
- Kana MFI ikaramba yakaderera, wedzeraTPU ye2–3 phrkuvandudza kuyerera uye kusimba kwemvura.
- Kusimbiswa kweFlame Retardancy:
- AHP inogona kuderedzwa kusvikaMapumburu gumi nemavirikana zvakabatana ne2–3 phr EGkuchengetedza UL94 V-0.
- ZveUL94 V-2, deredza zvinhu zvinodzora moto kuti uise pamberi simba/kuyerera kwemvura.
- Maparamita Ekugadzira Jekiseni:
- Tembiricha:180–220°C(dzivisa kukanganiswa kweAHP/HIPS).
- Kumhanya kwejekiseni:Pakati nepakati-yakakwirirakudzivirira kuzadza kusina kukwana.
Kushanda Kunotarisirwa:
| Pfuma | Kukosha kweTarget | Mwero wekuyedza |
| Simba remhedzisiro | ≥7 kJ/m² | ISO 179/1eA |
| MFI (200°C/5 kg) | 5–7 g/10min | ASTM D1238 |
| Kunonoka kwemurazvo | UL94 V-0 (1.6 mm) | UL94 |
| Simba rekusimba | ≥25 MPa | ISO 527 |
4. Mhinduro Dzakasiyana
- Sarudzo Inonyanya Kukoshesa Mari: Tsiva AHP zvishoma nephosphorus tsvuku yakavharirwa muzvikamu zvidiki (3–5 phr), asi cherechedzai muganhu weruvara (tsvuku-tsvuku).
- Kusimbiswa: Itai miedzo midiki yekuenzanisa kukanganiswa kwesimba nemoto usati wanyatso fambisa mvura.
