C --> D [Ukwelapha Kwezinga Lokushisa Okuphezulu (120-150°C)] --> E [Indwangu Eyisisekelo (Indwangu Elukiwe/Indwangu Engalukiwe)]
E --> F [Embossing Surface/Matting Treatment]
Inqubo Ye-Solvent-Free: Akukho ukukhishwa kwe-molecule encane ngesikhathi senqubo yokwelapha (VOC ≈ 0)
Indlela Yokumisa Yendwangu Eyisisekelo: I-Hot Melt Adhesive Point Bonding (hhayi i-PU Impregnation), Ukulondoloza I-Base Fabric Breathability
2. Ukushiyeka Kwezinqubo Zendabuko Zokwenziwa Kwesikhumba
- Isikhumba se-PU: I-DMF Emanzi Yokumila → Isakhiwo Esincane Esincane Kodwa I-Residual Solvent (Idinga Ukugeza Amanzi, Isebenzisa amathani angu-200/10,000 wamamitha)
- Isikhumba se-PVC: Ukufuduka kwe-Plasticizer (I-3-5% Ikhishwa minyaka yonke, eholela ku-Brittleness)

I-Flame Retardancy: UL94 V-0 (Isikhathi Sokuzicisha < 3 imizuzwana)
Ukukhishwa kwe-VOC: <5 μg/m³ (ISO 16000-6)
Ukuvumelana nezimo Zezinga Eliphansi: Iyagobeka ku-60°C (Akukho ukuqhekeka)
2. I-PU Synthetic Isikhumba: I-Yellowing Resistance: ΔE > 8.0 (amahora angu-200)
Ukumelana ne-Hydrolysis: Ukuqhekeka ku-70°C amahora angama-96 (ASTM D2097)
I-Flame Retadancy: UL94 HB (Ukushiswa Kancane)
Ukukhishwa kwe-VOC: > 300 μg/m³ (Iqukethe i-DMF/Toluene)
Ukuvumelana nezimo Kwezinga Eliphansi: Ibhilide ku -20°C
3. I-PVC Synthetic Isikhumba: Ukumelana Okuphuzi: ΔE > 15.0 (amahora angu-100)
I-Hydrolysis Resistance: Ayisebenzi (Ayifanele ukuhlolwa)
I-Flame Retardancy: UL94 V-2 (I-Dripping Ignition)
Ukukhishwa kwe-VOC: >> 500 μg/m³ (kuhlanganise ne-DOP)
Ukuvumelana nezimo Zezinga Eliphansi: Kwelapheka ku-10°C
IV. Izici Zemvelo Nokuphepha
1. Isikhumba Silicone:
I-Biocompatibility: I-ISO 10993 yebanga lezokwelapha eqinisekisiwe (izinga lokufakelwa)
I-Recyclability: Amafutha e-Silicone atholakala ngokuqhekeka okushisayo (izinga lokubuyisela> 85%)
Izinto Ezinobuthi: I-Heavy metal-free/halogen-free
2. Isikhumba Sokwenziwa
I-Biocompatibility: Ingozi yokucasuka kwesikhumba (iqukethe ama-isocyanate amahhala)
Ukuphinda kusetshenziswe kabusha: Ukulahlwa kweLapho (akukho ukucekelwa phansi phakathi neminyaka engama-500)
Izinto Ezinobuthi: I-PVC iqukethe i-lead stabilizer, i-PU iqukethe i-DMF
Ukusebenza Komnotho Oyindilinga: Isikhumba se-Silicone singakhumulwa ngokoqobo kusuka endwangu eyisisekelo kuya kusendlalelo se-silicone ukuze siphindwe kabusha. Isikhumba se-PU/PVC singehliswa kuphela futhi sigaywe kabusha ngenxa yokuxhumanisa kwamakhemikhali. V. Izimo Zokusebenza
I-Silicone Leather Izinzuzo

- Izingxenye zefenisha ezingawuthwali umthwalo (isb., izinhlangothi zamadrowa) VI. Ukuqhathaniswa Kwezindleko Nesikhathi Sokuphila
1. Isikhumba Se-Silicone: Izindleko Zempahla Engavuthiwe --- $15-25/m² (Silicone Oil Purity > 99%)
Ukusetshenziswa Kwamandla Okucutshungulwa -- Kuphansi (Ukuphulukiswa Ngokushesha, Akukho Ukugeza Amanzi Okudingekayo)
Impilo Yesevisi -- > Iminyaka eyi-15 (Isimo Sezulu Esisheshayo Sangaphandle Siqinisekisiwe)
Izindleko Zokulungisa -- Sula Ngokuqondile Ngotshwala (Akukho Ukulimala)
2. Isikhumba Se-Silicone: Izindleko Zempahla Engavuthiwe --- $8-12/m²
