Chemical Purification and Natural Corrosion Restoration
Passivation is a specialized chemical bath for stainless steel. Cutting welding and machining leave free iron particles on metal surfaces that can rust. Passivation dissolves these surface impurities and helps a fresh protective chromium oxide layer form quickly.
تزيل معالجة التخميل شوائب الحديد والملوثات الناتجة عن اللحام للقطعة الفولاذية مما يعيد بناء طبقة الكروم الواقية بسرعة.
Essential Standards for Food Hygiene and Medical Safety
Because passivation leaves a completely clean non reactive surface without altering component size, it is essential for medical instruments food handling equipment beverage tanks and marine valves.
تعد معالجة التخميل ضرورية لمعدات الأغذية والمستلزمات الطبية لضمان النظافة التامة ومنع التفاعل الكيميائي.
