Film Technologies for Advancing Building Skin Features

Sebastian Zehentmaier, Application Engineering Specialist, 3M
Fluoropolymers are well known materials in the architectural industry. Films made from these materials can be made into aesthetically pleasing building skins. But it’s a challenge to bond them to other materials. Multilayer optical film technologies can be used to manage building features while maintaining architectural aesthetics. The technology has been applied, for example, to the creation of visibly transparent IR mirror films, visible mirrors and decorative films. But not all of these are outdoor stable. 3M‘s proprietary nanostructuring process allows for almost universal bonding of fluorpolymers. But a process needs to be applied to a material to become a product.

Corrosion Inhibition Model for Aluminuim by Sodium Caboxyt Methyl Cellulose (Polymer) in Acidic Solution

Macdenis Egbuhuzor, Technologist in Charge of Process Laboratory, University of Nigeria Nsukka
We studied the efficiency of sodium carboxy methyl cellulose (a Polymer) in the inhibition and control of corrosion of aluminum on acidic medium. Sodium carboxymethyl cellulose was diluted into five different concentration levels and applied on several prepared and polished aluminum coupons for a weight loss experiment. Metal coupons previously cleansed and weighed were totally immersed in 100ml of 0.5M solution of HCl in an open beaker. The beaker was placed in a water bath maintained at varying temperatures. The procedures were conducted with and without the various concentrations of the inhibitor (Na-CMC) at temperatures 35oC, 45C, 55C, and 65C. At every time interval, the immersed metal specimen was withdrawn from the test solution, washed, dried and reweighed. The weight loss being the difference in weight of the specimen before and after immersion in the water bath was recorded for every coupon sample. The effects of concentration, temperature and time on weight loss, corrosion rate and inhibition efficiency were studied from the various plots and from the graph, it was observed that increase in the concentration of the inhibitor increases the inhibition efficiency. Also increase in the temperature of the operating environment decease the inhibition efficiency and vice versa. The relationship between the inhibitor efficiency, IE; concentration, C; temperature, T; and time t, was established through a model IE= 58.4770C0.5148-0.8913T + 50.4194t-0.1061, the proportion of variance explained (R^2) = 0.9128 (91.28%) and the prob(t) is 0.00001. Keywords: corrosion, weight loss, aluminium, inhibition efficiency, concentration.
