Talooyinka Naqshadeynta Qaab-dhismeedka Ka-hortagga Dabka ee Polystyrene-ka Saameynta Sare Leh ee aan Halogen-ka lahayn (HIPS)
Shuruudaha MacaamiishaHIPS-ka dabka celiya ee loogu talagalay guryaha qalabka korontada, xoogga saameynta ≥7 kJ/m², tusmada socodka dhalaalka (MFI) ≈6 g/10 daqiiqo, qaabaynta duritaanka.
1. Nidaamka Fosfooraska-Nitrogen-ka ee Isku-dhafka ah
Qaabaynta HIPS-ka ee ka hortagga ololka (Jadwalka 1)
| Qaybta | Soo raraya (phr) | Faallooyin |
| Reesinka miskaha | 100 | Alaab saldhig ah |
| Ammonium polyphosphate (APP) | 15-20 | Ilaha Fosfooraska |
| Melamine cyanurate (MCA) | 5-10 | Isha Nitrogen-ka, waxay la midowdaa APP-da |
| Graphite la ballaariyay (EG) | 3-5 | Waxay xoojisaa sameynta qaab-dhismeedka |
| Wakiilka ka hortagga dhibcaha (PTFE) | 0.3-0.5 | Waxay ka hortagtaa dhibcaha dhalaalay |
| Iswaafajinta (tusaale ahaan, HIPS-ka MAH-lagu dhejiyay) | 2-3 | Waxay hagaajisaa kala firdhinta |
Astaamaha:
- GuuloUL94 V-0iyada oo loo marayo sameynta qaab-dhismeed gudaha ah oo ka imanaya iskaashiga APP/MCA.
- Halogen-la'aan iyo deegaan-saaxiibtinimo, laakiin waxay yareyn kartaa sifooyinka farsamada; hagaajinta ayaa loo baahan yahay.
2. Nidaamka Ka-hortagga Ololka ee Birta Haydarojiin
Qaabaynta HIPS (Jadwalka 2)
| Qaybta | Soo raraya (phr) | Faallooyin |
| Reesinka miskaha | 100 | - |
| Aluminium hydroxide (ATH) | 40-60 | Qalabka dab-damiska aasaasiga ah |
| Magnesium hydroxide (MH) | 10-20 | Waxay la shaqaysaa ATH |
| Wakiilka isku xidhka Silane (tusaale ahaan, KH-550) | 1-2 | Waxay hagaajisaa kala firdhinta buuxinta |
| Xoojiye (tusaale ahaan, SEBS) | 5-8 | Waxay magdhowdaa khasaaraha xoogga saameynta |
Astaamaha:
- Waxay u baahan tahay>50% raristaee UL94 V-0, laakiin waxay hoos u dhigtaa xoogga saameynta iyo socodka.
- Ku habboon codsiyada qiiqa yar/sumowga yar (tusaale ahaan, gaadiidka tareenka).
3. Nidaamka Isku-dhafka ah ee Fosfooraska-Nitrogen (Aluminium Hypophosphite + MCA)
Qaab-dhismeedka HIPS ee la Hagaajiyay
| Qaybta | Soo raraya (phr) | Shaqada/Qoraallada |
| HIPS (heerka saamaynta sare leh, tusaale ahaan, PS-777) | 100 | Agabka salka (saameyn ≥5 kJ/m²) |
| Aluminium hypophosphite (AHP) | 12-15 | Isha fosfooraska, xasilloonida kulaylka |
| Melamine cyanurate (MCA) | 6-8 | Ilaha Nitrogen-ka, wuxuu la midoobaa AHP |
| SEBS/SBS | 8-10 | Adkayn muhiim ah oo saameyn leh ≥7 kJ/m² |
| Saliid soybean ah oo dareere ah oo paraffin/epoxide ah | 1-2 | Saliidayn, waxay hagaajisaa socodka/fiditaanka |
| PTFE | 0.3-0.5 | Wakiilka ka hortagga daadinta |
| Antioxidant 1010 | 0.2 | Waxay ka hortagtaa burburka |
Tixgelinta Naqshadeynta Muhiimka ah:
- Xulashada Resin-ka:
- Adeegso darajooyinka HIPS ee saamaynta sare leh (tusaale ahaan,Chimei PH-888,Taifa PG-33) oo leh xoog saameyn ku dhisan oo ah 5-6 kJ/m². SEBS waxay sii xoojisaa adkeysiga.
- Xakamaynta Socodka:
- AHP/MCA waxay yareeyaan MFI; waxay ku magdhabaan saliidaha (tusaale ahaan, paraffin dareere ah) ama balaastig-sameeyayaasha (tusaale ahaan, saliidda soybean-ka ee epoxidized).
- Haddii MFI uu hooseeyo, ku dar2–3 phr TPUsi loo hagaajiyo socodka iyo adkaanta.
- Xaqiijinta Dib-u-Celinta Ololka:
- AHP waxaa loo dhimi karaa ilaa12 saacadoodhaddii la isku daro2–3 phr EGsi loo ilaaliyo UL94 V-0.
- Waayo,UL94 V-2, yaree rarista dab-damiska si loo kala hormariyo saameynta/socodka.
- Halbeegyada wax lagu duro:
- Heerkulka:180–220°C(ka fogow burburka AHP/HIPS).
- Xawaaraha duritaanka:Dhexdhexaad-saresi looga hortago buuxinta aan dhammaystirnayn.
Waxqabadka la filayo:
| Hantida | Qiimaha Bartilmaameedka | Heerka Imtixaanka |
| Xoogga saameynta | ≥7 kJ/m² | ISO 179/1eA |
| MFI (200°C/5 kg) | 5–7 g/10 daqiiqo | ASTM D1238 |
| Dabacsanaanta ololka | UL94 V-0 (1.6 mm) | UL94 |
| Xoogga jiidista | ≥25 MPa | ISO 527 |
4. Xalalka Kale
- Ikhtiyaarka Xasaasiga ah ee Kharashka: Ku beddel qayb ahaan AHPFosfooraska cas ee yar yar ee la dahaadhay (3-5 phr), laakiin ogow xaddidaadda midabka (casaan-bunni).
- Xaqiijinta: Samee tijaabooyin yar yar si loo dheellitiro saameynta iyo dib u dhaca dabka ka hor inta aan la hagaajin socodka.
