Inkasta oo maqaar silikoon ah iyo maqaar synthetic labaduba ay hoos yimaadaan qaybta maqaar macmal ah, waxay ku kala duwan yihiin asal ahaan kiimikaadkooda, saaxiibtinimo deegaanka, cimri dhererka, iyo sifooyinka shaqada.

Farqiga Kiimikada: Silikoon's laf-dhabarta inorganic waxay bixisaa xasillooni aan caadi ahayn, halka silsiladaha organic ee PU/PVC ay u nugul yihiin daxalka deegaanka. II. Farqiga Muhiimka ah ee Hannaanka Wax Soo Saarka
1. Habka Muhiimka ah ee Maqaarka Silikoon
A [Salidka Silikoon + Isku-darka Buuxinta] --> B [Diritaanka Platinum Catalyst] --> C
C --> D [Daawaynta Heerkulka Sare (120-150°C)] --> E
E --> F

Habka Fabric Lamination ee Saldhigga: Isku-xidhka Dheefta Kulul ee Kulul (ma aha Impregnation PU), Ilaalinta Neefsashada Dharka Saldhigga
2. Niyad-jabka Hannaanka Maqaar-Dhaqameed

2. Maqaarka synthetic PU: Caabbinta Jaallaha: ΔE> 8.0 (200 saacadood)
Iska caabinta Hydrolysis: Dilaaca at 70 ° C 96 saacadood (ASTM D2097)

3. Maqaarka synthetic ee PVC: Caabbinta Jaallaha ah: ΔE> 15.0 (100 saacadood)
Iska caabinta Hydrolysis: Ma khuseyso (ma khuseyso baaritaanka)
Dib u Celinta Ololka: UL94 V-2 (Diddhicidda)
Sii daynta VOC: >> 500 μg/m³ (ay ku jirto DOP)

IV. Tilmaamaha Deegaanka iyo Badbaadada
1. Hargaha Silikoon:
Biocompatibility: ISO 10993 heerka-caafimaadka oo la xaqiijiyay (heerka maqaar-galaha)

Walxaha Sunta ah: Biraha culus ee bilaa birta ah/halogen-la'aanta ah
2. Maqaarka synthetic
Biocompatibility: Khatarta cuncunka maqaarka (waxaa ku jira isocyyanates bilaash ah)
Dib-u-warshadaynta: Qashin qubka (wax xaaluf ah ma jiro 500 sano gudahood)
Walxaha Sunta ah: PVC waxa ku jira xasiliye cusbo leh, PU waxa ku jira DMF
Waxqabadka Dhaqaalaha Wareega: Maqaarka Silikoon ayaa jir ahaan laga siibi karaa dharka salka ilaa lakabka silikoon si dib loogu soo celiyo. Maqaarka PU/PVC waa la dhimi karaa oo dib loo warshadayn karaa sababtoo ah isku xidhka kiimikada. V. Xaaladaha Codsiga
Faa'iidooyinka maqaarka ee Silikoon
- Daryeelka caafimaadka:
- JIS L1902.
- Miisaska qalliinka antistatic ayaa daboolaya (iska caabbinta dushiisa 10⁶-10⁹ Ω)
- Baabuurta Tamarta Cusub:
-Kuraasta cimiladu u adkaysan karto (-40°C ilaa 180°C heerkulka shaqaynta)

Codsiyada Maqaarka Synthetic
- Isticmaalka muddada gaaban:
- Bacaha moodada degdega ah (maqaarka PU waa mid fudud oo qiimo jaban)
- muraayadaha muraayadda ee la tuuri karo (qiimaha maqaarka PVC <$5/m²)

Habka Isticmaalka Tamarta -- Sare (khadka farsamaynta qoyan wuxuu cunaa 2000kWh/10,000 mitir)
Nolosha Adeegga --> 3-5 Sano (Hydrolysis and Pulverization)
Kharashka Dayactirka -- Waxa uu u baahan yahay Nadiifiyeyaasha Khaaska ah
TCO (Qiimaha Wadarta Lahaanshaha): Maqaarka Silikoonku wuxuu ku kacayaa 40% in ka yar maqaar PU muddo 10 sano ah (oo ay ku jiraan beddelka iyo kharashyada nadiifinta). VII. Tilmaamaha Hagaajinta Mustaqbalka
