1. Ki sa ki pwopriyete yo materyèl kle yo mande pou jwen papye aliminyòm?
High-purity aluminum (≥99.5%) ensures corrosion resistance in chemical environments. Annealed foil with 0.1–0.5mm thickness balances flexibility and sealing pressure. ASTM B479 standards define tensile strength (>80 MPa) pou aplikasyon pou gasket. Polymer Coatings (egzanp, PTFE) Amelyore anti - Pèfòmans baton pa 40-60%. Mikwo - sifas Relief amelyore pousantaj rekiperasyon konpresyon a 90-95%.
2. Kijan chenn tanperati a afekte pèfòmans gasket aliminyòm?
Continuous service at -70°C to +315°C requires alloy additives like silicon (1–3%). Thermal cycling tests show ≤0.2% permanent deformation after 500 cycles. Cryogenic applications use laminated foil with fiberglass interlayers. Excessive heat (>400 degre) Akselere oksidasyon, diminye validite pa 50-70%. Pousantaj ekspansyon diferans yo dwe matche ak materyèl bride (egzanp, asye pur).
3. Ki sa ki endistri majorite sèvi ak jwen papye aliminyòm ak poukisa?
Otoklav famasetik konte sou jwen papye pou sele esteril (ISO 13485 konfòme). Semiconductor fab itilize ultra - vèsyon pwòp ak<0.01μg/cm² particle shedding. Automotive exhaust systems prefer perforated foil-asbestos composites. Aerospace hydraulic systems require fireproof variants (FAR 25.853 certified). Cost-effectiveness drives adoption in HVAC duct joints.
4. Ki sa ki se mòd echèk komen nan jwen papye aliminyòm?
Creep deformation under sustained load (>10 kN/m) causes 80% of leaks. Chloride-induced pitting occurs in coastal environments within 6–12 months. Improper flange surface finish (Ra >3.2μm) mennen nan konpresyon inegal. Vibration fatig fant kòmanse nan Stamping bor apre 5 × 10⁶ sik. Enkonpatibilite chimik (egzanp, asid fò) fonn kouch oksid pwoteksyon.
5. Kouman se kontwòl kalite aplike nan pwodiksyon gasket papye?
Eskanè epesè lazè detekte ± 5μm devyasyon nan reyèl - tan. Tès elyòm fwit verifye poze sele nan 10⁻⁶ mbar · l/s papòt. X - Ray fluoresans konfime konpozisyon alyaj nan ± 0.3%. Konpresyon - Mete tès swiv pwotokòl ASTM F36. Sistèm vizyon otomatik enspekte 200+ garnitur/minit pou domaj sifas yo.
