Kunyangwe ese ari maviri ematehwe e-silicone nematehwe ekugadzira achiwira pasi pechikamu chematehwe ekugadzira, anosiyana zvakanyanya mumakemikari avo, hushamwari hwezvakatipoteredza, kusimba, uye mashandiro anoita zvinhu. Izvi zvinotevera zvakarongeka zvinozvienzanisa kubva pamaonero ekuumbwa kwezvinhu, maitiro maitiro, uye mamiriro ekushandisa:
I. Material Nature uye Chemical Structure Kusiyana
Zvikamu Zvikuru: Inorganic siloxane polymer (Si-O-Si musana), organic polymer (CON cheni dzePU/C-Cl cheni dzePVC)
Crosslinking Method: Platinum-catalyzed yekuwedzera mushonga (byproduct-isina), solvent evaporation/isocyanate reaction (ine VOC zvakasara)
Molecular Stability: Kunyanya kusagadzikana kwemamiriro ekunze (Si-O bond simba> 460 kJ/mol), nepo PU inotapukirwa nehydrolysis (ester bond simba <360 kJ/mol)
Musiyano Wemakemikari: Silicone's inorganic musana inopa kugadzikana kwakasiyana, nepo organic cheni yePU/PVC inotapukirwa nekuora kwezvakatipoteredza. II. Misiyano Yakakosha muMaitirwo Ekugadzira
1. Silicone Leather Core Process
A [Silicone Mafuta + Musanganiswa Wekuzadza] --> B [Platinum Catalyst Jekiseni] --> C [Release Pepa Carrier Coating]
C --> D [Kurapa Kwekupisa Kwepamusoro (120-150°C)] --> E [Mucheka Wakarukwa/Mucheka Usina Kurukwa)]
E --> F [Surface Embossing/Matting Treatment]
Solvent-Yemahara Maitiro: Hapana diki molecule inoburitswa panguva yekurapa maitiro (VOC ≈ 0)
Base Fabric Lamination Method: Kupisa Melt Adhesive Point Bonding (kwete PU Impregnation), Kuchengetedza Base Fabric Breathability
2. Kukanganisa kweTraditional Synthetic Leather Processes
- PU Leather: DMF Wet Impregnation → Microporous Structure asi Residual Solvent (Inoda Kugezwa Mvura, Kushandisa 200 Matani/10,000 Mamita)
- PVC Leather: Plasticizer Migration (3-5% Inosunungurwa Gore negore, Inotungamira kune Brittleness)
III. Performance Parameter Kuenzanisa (Yakayerwa Dhata)

Hydrolysis Resistance: Hapana kuputika pa100 ° C kwemaawa 720 (ASTM D4704)
Flame Retardancy: UL94 V-0 (Self-Etinguishing Time < 3 seconds)
VOC Emissions: <5 μg/m³ (ISO 16000-6)
Yakaderera-Temperature Flexibility: Inobhenda pa60°C (Hapana kutsemuka)
2. PU Synthetic Leather: Yellowing Resistance: ΔE > 8.0 (200 maawa)
Hydrolysis Resistance: Kutsemuka pa70°C kwemaawa makumi mapfumbamwe nematanhatu (ASTM D2097)
Flame Retadancy: UL94 HB (Slow Burning)
VOC Emissions: > 300 μg/m³ (Ine DMF/Toluene)
Kudzika-Tembiricha Kuchinjika: Brittle pa -20°C
3. PVC Synthetic Leather: Yellowing Resistance: ΔE > 15.0 (100 maawa)
Hydrolysis Resistance: Hazvishande (Hazvina basa pakuyedzwa)
Flame Retardancy: UL94 V-2 (Dripping Ignition)
VOC Emissions: >> 500 μg/m³ (kusanganisira DOP)
Kudzika-Tembiricha Kuchinja: Inorapa pa10°C
IV. Environmental and Safety Features
1. Silicone Leather:
Biocompatibility: ISO 10993 yekurapa-giredhi yakasimbiswa (implant standard)
Kudzokororwazve: Mafuta eSilicone akadzorerwa kuburikidza nekuputika kwemafuta (chiyero chekudzorera> 85%)
Chepfu Zvinhu: Heavy simbi-isina/halogen-isina
2. Synthetic Leather
Biocompatibility: Kushatirwa kweganda njodzi (ine yemahara isocyanates)
Recyclability: Kurasa marara (hapana kushatiswa mukati me500 makore)
Zvinhu zvine Chepfu: PVC ine lead salt stabilizer, PU ine DMF
Circular Economy Performance: Dehwe reSilicone rinogona kubviswa kubva pachigadziko chejira kusvika kune silicone layer yekudzoreredza granulation. PU/PVC dehwe rinogona kungodzikiswa uye kudzokororwa nekuda kwemakemikari muchinjiko. V. Mamiriro Ekushandisa
Silicone Leather Advantages
- Nezveutano:
- Antibacterial mattresses (MRSA inhibition rate> 99.9%, inoenderana neJIS L1902)
-Antistatic yekuvhiya tafura inovhara (yepamusoro resistivity 10⁶-10⁹ Ω)
-Motokari Itsva dzeMagetsi:
- Zvigaro zvinodzivirira mamiriro ekunze (-40°C kusvika 180°C kushanda tembiricha)
- Yakaderera-VOC yemukati (inosangana neVolkswagen PV3938 yakajairwa)
- Outdoor Equipment:
- UV-inodzivirira zvigaro zvechikepe (QUV 3000-awa ΔE <2)
-Kuzvichenesa matende (mvura yekubata angle 110 °)
Synthetic Leather Applications
-Kushandiswa kwenguva pfupi:
-Mabhegi efashoni anokurumidza (PU ganda rakareruka uye rakadhura)
- Inoraswa kuratidza vheji (PVC yematehwe mutengo <$5/m²)
-Kusina-kusangana Zvikumbiro:
- Isiri-inotakura-inotakura fenicha zvikamu (semuenzaniso, madhirowa mamberi) VI. Mutengo uye Hupenyu Kuenzanisa
1. Silicone Leather: Raw Material Cost --- $15-25/m² (Silicone Oiri Kuchena > 99%)
Maitiro Ekushandisa Simba -- Yakaderera (Kukurumidza Kurapa, Hapana Kugeza Mvura Inodiwa)
Hupenyu hweSevhisi -> Makore gumi nemashanu (Panze Yakakurumidza Kumira Kwemamiriro ekunze Yakasimbiswa)
Mutengo Wekugadzirisa -- Direct Pukuta neDoro (Hapana Kukuvadza)
2. Silicone Leather: Raw Material Cost --- $8-12/m²
Process Energy Consumption - Yakakwirira (Wet-processing line inoshandisa 2000kWh/10,000 metres)
Hupenyu hweSevhisi -> 3-5 Makore (Hydrolysis uye Pulverization)
Mutengo Wekugadzirisa -- Unoda Specialized Cleaners
TCO (Total Cost of Ownership): Dehwe reSilicone rinodhura 40% pasi pePU yematehwe pamusoro pemakore gumi (kusanganisira kutsiva nekuchenesa mari). VII. Remangwana Upgrade Madirections
-Silicone Leather:
- Nanosilane Kugadziriswa → Lotus Leaf-senge Superhydrophobicity (Bata Angle> 160°)
- Emb
