Anadik oksidlanish plitalari uchun alyuminum qotishma nima?
6xxx seriyali (al-MG-Si), bu uning muvozanatli anadirmaydigan javobi va tarkibiy kuchi tufayli ko'pincha qo'llaniladi. 1xxx seriyali oksidi "Okspa", ammo cheklangan mexanik xususiyatlarni taqdim etadi. Mis-boy 2xxx seriyali korroziyani oldini olish uchun maxsus xrom kislotasini ankalashtiradi. 5xxx seriyasi oksidlanishdan yuqori soyaga chidamlilikni namoyish etadi, ammo kulrang ranglar paydo bo'lishi mumkin. Zamonaviy ishlanmalarga bo'yalgan temir tarkibiga (0,15-0,35%) bo'yashni singdirishini kuchaytirish uchun o'zgartirilgan 6xxx qotishmalari mavjud.
Yuzaki tayyorlash oksidlangan alyumin plitalarining sifatiga qanday ta'sir qiladi?
Mexanik parlatishga erishish kerak<0.2μm roughness for decorative applications. Alkaline etching (50-70g/L NaOH at 50°C) removes 3-5μm surface layer to expose fresh aluminum. Electropolishing with phosphoric acid improves reflectivity before hard anodizing. Ultrasonic degreasing eliminates organic contaminants that cause uneven oxidation. A desmutting step using 30% nitric acid is critical after etching to remove intermetallic particles.
Turli oksidlanish jarayoni orqali qanday qalinlikka erishish mumkin?
Oddiy anadizatsiya me'moriy dasturlar uchun 5-25 mkmlarni 5-25 mkment peparatlarini ishlab chiqaradi. Qattiq anadizing (15-20V, 0-5 daraja) CareceUce Carece uchun 50-100 mmetr qatlamlarini quradi. Mikro ark oksidlanishi 1500 soat qattiqlik bilan 10-300 mmkmik palitsni yaratadi. Yupqa metall elektrolitik oksidlanish (TFO) elektronika uchun 1-5 mmm. O'sish sur'ati odatda elektrolit konsentratsiyasiga qarab 0,5-1,5 mkm / minut.
Muhr qilish muolajalari oksidiyalangan alyuminiy plitaning ishlashini kuchaytiradimi?
Hot water sealing (95-100°C) hydrates the porous layer to improve corrosion resistance. Nickel acetate sealing provides superior dye retention for colored components. Cold sealing with fluorides reduces energy consumption by 60% compared to traditional methods. Chromate sealing offers maximum protection for marine applications but faces environmental restrictions. Advanced plasma electrolytic sealing can achieve hydrophobic surfaces with >150 daraja suv bilan aloqa qilish burchagi.
Qanday sifat sinovlari oksidiya platentsian sanoat standartlariga muvofiqligini tekshiradimi?
Qoplamali qalinlik Eddy oqimini (ISO 2360) yoki kesma mikroskopik (ASTM B487) orqali o'lchanadi. Tuzni püskürtmen sinovi (ASTM B117) 1000+ dan keyin korroziya qarshiligini baholaydi. Aşeryuzaga chidamlilik Taber Test (CS-10 g'ildirak, 1000 tsikl) bilan miqdoriy hisoblangan. Rang izchillik spektrofotometriyasi (dr<1.5 for architectural grades). Adhesion is verified through tape tests (ISO 2819) and bend tests (180° without cracking).
