Ngakhale zikopa zonse za silicone ndi zikopa zopanga zimagwera m'gulu la zikopa zopangira, zimasiyana kwambiri pamankhwala awo, kuyanjana kwachilengedwe, kulimba, komanso magwiridwe antchito. Zotsatirazi zimawafananiza mwadongosolo kuchokera kumawonekedwe azinthu, mawonekedwe azinthu, ndi momwe amagwiritsidwira ntchito:
I. Kusiyanasiyana kwa Zakuthupi ndi Kapangidwe ka Mankhwala
Zigawo Zazikulu: Inorganic siloxane polima (Si-O-Si msana), organic polima (CON maunyolo a PU/C-Cl unyolo wa PVC)
Crosslinking Method: Platinum-catalyzed supplement cure (yopanda mankhwala), solvent evaporation/isocyanate reaction (ili ndi VOC zotsalira)
Kukhazikika kwa Mamolekyulu: Kusagwira kwanyengo kwambiri (Si-O bond energy> 460 kJ/mol), pomwe PU imatha kutenga hydrolysis (ester bond energy <360 kJ/mol)
Kusiyana kwa Chemical: Msana wa silicone umapangitsa kukhazikika kwapadera, pomwe maunyolo achilengedwe a PU/PVC amatha kuwonongeka ndi chilengedwe. II. Kusiyana Kwakukulu mu Njira Zopangira
1. Silicone Leather Core Process
A [Mafuta a Silicone + Kusakaniza Kodzaza] --> B [Jakisoni Wothandizira wa Platinamu] --> C [Kutulutsa Chonyamula Mapepala]
C --> D [Kuchiritsa Kutentha Kwambiri (120-150°C)] --> E [Nsalu Yothirira (Nsalu Yolukidwa/Nsalu Yosalukidwa)]
E --> F [Kukometsera Pamwamba / Chithandizo cha Matting]
Njira Yaulere Yosungunulira: Palibe molekyu yaying'ono yomwe imatulutsidwa panthawi yochiritsa (VOC ≈ 0)
Base Fabric Lamination Method: Hot Melt Adhesive Point Bonding (osati PU Impregnation), Kusunga Base Fabric Breathability
2. Zoperewera za Njira Zachikhalidwe Zopangira Chikopa
- PU Chikopa: Kulowetsedwa Konyowa kwa DMF → Kapangidwe Kang'ono Komwe Kusungunula Kotsalira (Kumafunika Kutsuka Madzi, Kugwiritsa Ntchito Matani 200/10,000 Mamita)
- Chikopa cha PVC: Kusamuka kwa Plasticizer (3-5% Kumasulidwa Pachaka, Kumatsogolera Ku Brittleness)
III. Kufananiza kwa Parameter ya Performance (Measured Data)
1. Chikopa cha Silicone: Yellowing Resistance --- ΔE <1.0 (QUV 1000 Hours)
Kukaniza kwa Hydrolysis: Palibe kusweka pa 100 ° C kwa maola 720 (ASTM D4704)
Kuchedwa kwa Flame: UL94 V-0 (Nthawi Yozimitsa Yokha <3 masekondi)
Kutulutsa kwa VOC: <5 μg/m³ (ISO 16000-6)
Kutentha Kwambiri Kusinthasintha: Kutha kupindika pa 60 ° C (Palibe kusweka)
2. PU Synthetic Chikopa: Yellowing Resistance: ΔE > 8.0 (200 hours)
Kukaniza kwa Hydrolysis: Kusweka pa 70 ° C kwa maola 96 (ASTM D2097)
Kuchedwa kwa Flame: UL94 HB (Kuwotcha Pang'onopang'ono)
Kutulutsa kwa VOC: > 300 μg/m³ (Muli DMF/Toluene)
Kutentha Kwambiri Kusinthasintha: Kukhazikika pa -20°C
3. PVC Synthetic Chikopa: Yellowing Resistance: ΔE > 15.0 (100 hours)
Kukaniza kwa Hydrolysis: Sizikugwira ntchito (Sizoyenera kuyesa)
Kuchedwa kwa Flame: UL94 V-2 (Dripping Ignition)
Kutulutsa kwa VOC: >> 500 μg/m³ (kuphatikiza DOP)
Kutentha Kwambiri Kusinthasintha: Amachiritsa pa 10°C
IV. Zachilengedwe ndi Chitetezo
1. Chikopa cha Silicone:
Biocompatibility: ISO 10993 Medical-grade Certified (implant standard)
Kubwezeretsanso: Mafuta a silicone adachira kudzera pakuwotcha kwamafuta (kuchira> 85%)
Zinthu Zapoizoni: Zopanda zitsulo zolemera/zopanda halogen
2. Chikopa Chopanga
Biocompatibility: Chiwopsezo cha kuyabwa pakhungu (chili ndi ma isocyanates aulere)
Kubwezeretsanso: Kutayira malo (palibe kuwonongeka mkati mwa zaka 500)
Zinthu Zapoizoni: PVC ili ndi lead salt stabilizer, PU ili ndi DMF
Magwiridwe Ozungulira Pachuma: Chikopa cha silikoni chimatha kuvula kuchokera pansalu yoyambira kupita ku gulu la silikoni kuti lipangidwenso. Chikopa cha PU/PVC chimangotsitsidwa ndikusinthidwanso chifukwa cholumikizana ndi mankhwala. V. Zochitika Zogwiritsira Ntchito
Ubwino wa Chikopa cha Silicone
- Chisamaliro chamoyo:
- Ma matiresi a antibacterial (MRSA inhibition rate> 99.9%, mogwirizana ndi JIS L1902)
- Zovundikira patebulo la opaleshoni ya antistatic (resistivity yapamwamba 10⁶-10⁹ Ω)
- Magalimoto Atsopano Amagetsi:
- Mipando yolimbana ndi nyengo (-40°C mpaka 180°C kutentha kwa ntchito)
- Low-VOC zamkati (amakumana ndi Volkswagen PV3938 muyezo)
- Zida Zakunja:
- Mipando ya ngalawa yosamva UV (QUV 3000-ola ΔE <2)
- Mahema odziyeretsa okha (ngodya yolumikizana ndi madzi 110 °)
Synthetic Chikopa Mapulogalamu
- Kugwiritsa Ntchito Nthawi Yaifupi:
- Matumba amafashoni othamanga (chikopa cha PU ndichopepuka komanso chotsika mtengo)
- Zowonetsera zotayidwa (mtengo wachikopa wa PVC <$ 5/m²)
- Mapulogalamu osalumikizana nawo:
- Zigawo za mipando zomwe sizikhala ndi katundu (mwachitsanzo, m'mphepete mwa magalasi) VI. Kuyerekeza kwa Mtengo ndi Umoyo Wathanzi
1. Chikopa cha Silicone: Mtengo Wopangira --- $15-25/m² (Kuyeretsedwa kwa Mafuta a Silicone> 99%)
Kugwiritsa Ntchito Mphamvu Zamagetsi -- Kutsika (Kuchiritsa Mwachangu, Palibe Kusamba Kwa Madzi Kofunikira)
Moyo Wautumiki --> Zaka 15 (Kuyendera Kwanyengo Kwakunja Kwatsimikizika)
Mtengo Wokonza -- Pukuta Mwachindunji ndi Mowa (Palibe Zowonongeka)
2. Chikopa cha Silicone: Mtengo Wopangira --- $8-12/m²
Kugwiritsa Ntchito Mphamvu Zamagetsi -- Kukwera (mzere wopangira madzi umadya 2000kWh/10,000 metres)
Moyo Wautumiki -> Zaka 3-5 (Hydrolysis ndi Pulverization)
Mtengo Wokonza -- Umafunika Oyeretsa Mwapadera
TCO (Total Cost of Ownership): Chikopa cha silicone chimawononga 40% poyerekeza ndi chikopa cha PU pazaka 10 (kuphatikiza ndalama zosinthira ndi kuyeretsa). VII. Njira Zokwezera M'tsogolo
- Chikopa cha Silicone:
- Kusintha kwa Nanosilane → Lotus Leaf-ngati Superhydrophobicity (Contact angle> 160°)
-Embe
