Preservation method for titanium alloy materials and products |
| Titanium plate industry has been developing rapidly in recent years, and the export range and quantity are also expanding constantly, with broad prospects. Is the titanium plate definitely not corroded? Decorative titanium plate corrosion, in addition to its own defects, and the environment, such as air humidity, air temperature, flow speed, flow direction, air containing impurities and the number of components have a great relationship. In the atmosphere and weak corrosive media because of the corrosion rate is less than 0.01mm/ year, is considered to be "completely corrosion resistant". But in CL - medium such as salt, sulfuric acid, oxalic acid is often used in engineering external wall cleaning, hydrochloric acid, porcelain brighteners interior corrosion in the cleaning supplies, neutral substances such as water should be used in the process of curing often clean in order to reduce corrosive medium adhesion and rust, also should avoid sharp objects scratch as (blade, titanium wire brush) in order to avoid affect the appearance and intergranular structure damage and corrosion. Preservation requirements for common titanium alloy materials and titanium products: 1) The site or warehouse for the storage of titanium plate products should be selected in the place with clean and clean, smooth drainage, and away from the factories and mines with harmful gases or dust. On the ground to clean up weeds and all sundries, maintain titanium material clean and tidy. 2) in the storehouse can not be stacked together with acid, alkali, salt, sensitive soil and other materials with denudation of titanium materials. Titanium materials of different varieties should be classified and stacked in order to avoid confuse and contact with corrosive objects. 3) Titanium alloy materials such as large titanium pipes, titanium rods, thick titanium plates, large diameter titanium pipes and titanium forgings can be stacked in the open air. 4) small and medium-sized model titanium, titanium plate, titanium rod, medium caliber titanium pipe, titanium wire, etc., can be stored and placed in the ventilated material barn, remember to cover up the mat. 5) Small size titanium material, thin titanium plate, titanium belt, small diameter or special shaped titanium pipe, all kinds of cold rolled, cold drawn titanium material and high price, easy to corrosion metal products, can be stored and placed in the warehouse. 6) The warehouse shall always maintain appropriate storage background, pay attention to ventilation in sunny days, and pay attention to closing moisture-proof in rainy days. 7) warehouse should be selected according to the geographical conditions, ordinary think appropriate and use the usual closed warehouse, that is, there is a roof with walls, a house tight, with ventilation device warehouse. |
