Talooyinka Nakhshadeynta Naqshadeynta Olol-Celin ee loogu talagalay Halogen- Saamaynta Sare ee Polystyrene (HIPS)
Shuruudaha Macaamiisha: Ololka HIPS ee guryaha qalabka korantada, xoogga saamaynta ≥7 kJ/m², index socodka dhalaalka (MFI) ≈6 g/10min, qaabaynta duritaanka.
1. Foosfooraska-Nitrogen isku-dhafan Nidaamka Dab-dejinta
HIPS-Qaabka Dib-u-dhigista Ololka (Shaxda 1)
| Qayb | Soodejinaya (phr) | Hadallo |
| Xabagta HIPS | 100 | Qalabka saldhigga ah |
| Ammonium polyphosphate (APP) | 15-20 | Fosfooraska isha |
| Melamine cyanurate (MCA) | 5-10 | Isha Nitrogen, waxay la shaqaysaa APP |
| Garaafka fidsan (EG) | 3-5 | Waxay kordhisaa samaynta char |
| Wakiilka ka-hortagga dareeraha (PTFE) | 0.3-0.5 | Waxay ka hortagtaa dhibco dhalaalka ah |
| Laqabsiyaha (tusaale, HIPS-ku-tallaalan MAH) | 2-3 | Waxay hagaajisaa kala firdhinta |
Astaamaha:
- GuuleystaUL94 V-0iyada oo loo marayo samaynta char intumescent ee ka imanaya is-dhexgalka APP/MCA.
- Halogen-free iyo deegaan-saaxiibtinimo, laakiin waxa laga yaabaa inay yarayso sifooyinka farsamada; wanaajinta ayaa loo baahan yahay.
2. Nidaamka Dib u Celinta Ololka Birta Hydroxide
Habka HIPS (Shaxda 2)
| Qayb | Soodejinaya (phr) | Hadallo |
| Xabagta HIPS | 100 | - |
| Aluminium hydroxide (ATH) | 40-60 | Dab-demiska aasaasiga ah |
| Magnesium hydroxide (MH) | 10-20 | Waxay la shaqaysaa ATH |
| Wakiilka isku xirka Silane (tusaale, KH-550) | 1-2 | Waxay hagaajisaa kala firdhinta buuxinta |
| Toughener (tusaale, SEBS) | 5-8 | Waxay magdhabisaa luminta xoogga saamaynta |
Astaamaha:
- u baahan>50% raristaloogu talagalay UL94 V-0, laakiin waxay hoos u dhigtaa saameynta xoogga iyo socodka.
- Ku habboon codsiyada qiiq-hoose/sumowga hooseeya (tusaale, gaadiidka tareenka).
3. Nidaamka Isku-dhafka Fosfooraska-Nitrogen (Aluminium Hypophosphite + MCA)
Habaynta HIPS ee la hagaajiyay
| Qayb | Soodejinaya (phr) | Shaqada/Xusuusyada |
| HIPS (darajada saamaynta sare leh, tusaale, PS-777) | 100 | Waxyaabaha salka (saamaynta ≥5 kJ/m²) |
| Aluminium hypophosphite (AHP) | 12-15 | Isha fosfooraska, xasilloonida kulaylka |
| Melamine cyanurate (MCA) | 6-8 | Isha Nitrogen, waxay la shaqaysaa AHP |
| SEBS/SBS | 8-10 | Adkeeye muhiim u ah saamaynta ≥7 kJ/m² |
| Saliid soybean ah oo dareere ah/epoxidized | 1-2 | Saliid, waxay wanaajisaa socodka/kala-firdhinta |
| PTFE | 0.3-0.5 | Wakiilka ka-hortagga dareeraha |
| Antioxidant 1010 | 0.2 | Waxay ka hortagtaa hoos u dhaca |
Tixgelinta Naqshadaynta Muhiimka ah:
- Xulashada xabagta:
- Isticmaal darajooyinka HIPS ee saamaynta sare leh (tusaale,Chimei PH-888,Taifa PG-33) oo leh awood saameyn dabiici ah oo ah 5-6 kJ/m². SEBS waxay sii kordhisaa adkaanta.
- Xakamaynta socodka:
- AHP/MCA waxay dhimaysaa MFI; ku magdhow saliidaha (tusaale, paraffin dareere ah) ama balaastikada (tusaale, saliid soybean ah oo epoxidized ah).
- Haddii MFI ay hooseyso, ku dar2-3 phr TPUsi loo hagaajiyo socodka iyo adkaanta.
- Xaqiijinta Dib u Dhaca Ololka:
- AHP waxaa lagu yarayn karaa12 phrhaddii lagu daro2-3 phr EGsi loo ilaaliyo UL94 V-0.
- WaayoUL94 V-2, yaree raritaanka ololka si loo kala hormariyo saamaynta/ socodka.
- Halbeegyada Habaynta Durida:
- Heerkulka:180-220°C(iska ilaali hoos u dhaca AHP/HIPS).
- Xawaaraha duritaanka:Dhexdhexaad-saresi looga hortago buuxinta aan dhamaystirnayn.
Waxqabadka la filayo:
| Hanti | Qiimaha Bartilmaameedka | Heerka Imtixaanka |
| Awood saamayn | ≥7 kJ/m² | ISO 179/1eA |
| MFI (200°C/5kg) | 5-7 g/10 daqiiqo | ASTM D1238 |
| Dib u dhaca ololka | UL94 V-0 (1.6 mm) | UL94 |
| Xoog xajin | ≥25 MPa | ISO 527 |
4. Xalka Beddelka ah
- Qiimaha xasaasiga ah ikhtiyaarkaAHP ku beddel qayb ahaanFosfooraska cas microencapsulated (3-5 phr), laakiin ogow xaddidnaanta midabka (guduud-brown).
- XaqiijintaSamee tijaabooyin yar-yar si loo dheellitiro saameynta iyo dib u dhaca ololka ka hor inta aan la wanaajin socodka.
