Application of titanium in the building industry
Application of titanium metal in the building materials is mainly based on pure titanium. Because it has many advantages, such as good formability, corrosion resistance, beautiful, high-grade, high concept and fashion. What's more, it has more features than the traditional copper, aluminum and stainless steel. More importantly, only titanium as building material can reach 100 years of quality assurance. In general, titanium metals as the most suitable for building materials is mainly based on the following characteristics:
Superior corrosion resistance: titanium surfaces will naturally form a layer of oxide film thickness less than 100A in the atmosphere, and the generated oxide film is extremely stable. So it can resist the corrosion of various kinds of environmental pollution, industrial radiation and extreme erosion of the atmospheric conditions; In addition, it can have superior corrosion resistance even in the coast area, acid rain area and Industrial pollution zone, and it can't fade because of the ultraviolet irradiation. It doesn't like stainless steel which is easy to have pitting corrosion, stress corrosion and crevice corrosion.
Environmental protection and energy saving: because titanium has a corresponding inert and non-toxic, it not only can't be decomposed, but also it can't indirectly pollute water source because of rain erosion. What's more, titanium can also be 100% recovered without lowering the level; Titanium doesn't pollute the environment, it accords with the requirements of the construction environmental protection. The thermal conductive coefficient of titanium is equal to the stainless steel. However, it’s just only 1/4 of the common steel, 1/8 of aluminum alloy, 1/20 of copper alloy, and it has the effect of maintaining the building temperature .So it can be regarded as the green environmental protection material.
Long life, remained unchanged for 100 years: when titanium is used for the roof and the external wall, the cost of initial material is higher than other metals. The costs of processing and installation are similar to other metals. However, the corrosion resistance of titanium makes it doesn't need to repair and constantly maintain. From the view of total life cycle cost, titanium has obvious superiority than other metals. Therefore, according to the long-term cost of operation, it has better advantages than other buildings metal materials.
