Lead coatings are mainly applied by cladding and find principal use in the chemical industry for resistance to sulphuric acid, for cable sheathing resistant to attack by soils and in architectural applications where resistance to industrial atmospheres is particularly good. They rely for their protective action on the formation of insoluble corrosion products which stifle the corrosion reaction and lead to very long service lives, but the corrosion resistance is impaired when chlorides are present. [Pg.458]

The trend in architectural applications has been towards more matt finishes, and the sodium hydroxide-based etchants used frequently contain additives such as sodium nitrate or nitrite or sodium fluoride. Chelating agents such as gluconates, heptonates or sorbitol are added to complex the aluminium produced, and other additives such as sulphides may be present in the etchant to complex zinc dissolved from the alloy, and allow it to be used continuously without dumping ... [Pg.701]

The atmospheric corrosion performance of the newer colour anodised finishes is of interest, and severtil authors have reported testsLongterm weathering of dyed finishes has also been described and this has led to the recommendation of a limited range of special dyes for architectural applications Good performance of the combined anodised and elec-trophoretically deposited clear lacquered finishes, now used very widely in Japan, has also been reported together with details of the vertical lines used to produce them . [Pg.704]

Other Types of Portland Cements. White Portland cement is standard Type I or III Pordand cement with raw materials selected and controlled to have negligible amounts of iron and manganese oxides, which impart the gray color. The white Pordand cement is used in decorative and architectural applications like precast curtain walls, terrazzo surfaces, stucco, tile grout, and decorative concrete. [Pg.323]

Other fibrous and porous materials used for sound-absorbing treatments include wood, cellulose, and metal fibers foamed gypsum or Portland cement combined with other materials and sintered metals. Wood fibers can be combined with binders and flame-retardent chemicals. Metal fibers and sintered metals can be manufactured with finely controlled physical properties. They usually are made for applications involving severe chemical or physical environments, although some sintered metal materials have found their way into architectural applications. Prior to concerns regarding its carcinogenic properties, asbestos fiber had been used extensively in spray-on acoustical treatments. [Pg.312]

The use of FRP in architectural applications has been going for many years. They are used to produce exterior decorative items such as cornices, facades, sky lights, etc. (Figure 23.11) and have also... [Pg.718]

The use of FRP is desired to replace older materials of construction such as concrete, stucco, etc. They have been used in many historical preservation projects. The reason they are desired is because of light weight, durability ease of installation, and low maintenance (no dry rot, attack by insects, mold, etc.). These are typically nonstructural parts made by spray-up process or continuous panel process. An example are shown in Figure 23.11. This market is expected to continue to grow. The main resin used for exterior architectural applications are halogenated polyester resins. Since there is not a smoke requirement, resins that meet the ASTM E-84 flame spread requirement of <25 can be used for this application. The other common material used for these applications is polyester resin or modified acrylic resins that are filled with ATH. The ATH filled resins can also be used in interior applications since they will typically also have low smoke values. [Pg.719]

The micro-scale science of nanotechnology may be in its infancy, but it offers great promise in the chemicals and coatings sector nonetheless. Nanotech advances will eventually affect everything from LEDs, where brighter monitors and displays may be possible, to slicker, denser paints for industrial, marine and architectural applications. [Pg.47]

Because they are very similar architecturally, applications written for Windows 95 will work with Windows 98, and those written for Windows NT will work with Windows 2000. Those written for the newer systems, however, are not always backward compatible. [Pg.633]

This approximate law holds for both native structure [22] and folding dynamics [2], In this regard, this wrapping motif may be regarded as a structural element that captures the basic component of energy transduction from hydrophobic association to structure formation. Furthermore, it implies that a fundamental constraint in protein architecture applicable to native structures applies also throughout the folding trajectory. [Pg.41]

The quantities of solvents in paints vary with desired characteristics (e.g., drying time desired) and application (building interiors, automotive surfaces, and architectural applications). Other solvents, including chlorinated hydrocarbons and terpenes, for example, are also formulated into paints. Virtually all solvent-based paints contain mixtures of lipophiles and hydrophiles. The exposures of painters to low levels of solvents (sufficiently low enough so that they do not experience acute symptoms at the time of exposure and below the TLVs for the individual solvent molecules) enables one to ascribe neurotoxicological reactions to low level mixture exposures. [Pg.309]

Design for corrosion resistance may be almost exclusively for appearance when favorable appearance is an economic advantage. Stainless steel and aluminum are frequently used for architectural applications and in food service largely for appearance. They also are used for trim on automobiles for the same reason. [Pg.4]

Other water-borne coatings include water-soluble emulsions, dispersions, and latex resins. Water-soluble resins are rare because most resins derived from vegetable oils are insoluble in water. The true emulsions are based on the emulsification of the oil or alkyd through either the action of a surfactant or a resin that has a surfactantlike character. The alkyd emulsions are readily prepared and can be used for OEM coatings and architectural applications. The submicron size droplets are stabilized by the thickeners (El-Aasser Sudol, 2004 Landfester, 2005 Landfester et al., 2004 Tsavalas et al., 2004 Weissenborn Motiejauskaite, 2000a,b). In dispersions, the resin is a solid and is dispersed in water. The latex resin is usually vinyl acetate, styrene, acrylates, or methacrylates radically copolymerized in a micelle to form particles 0.1 pm in diameter (Bloom et al., 2005 Brister et al., 2000 Jiratumnukul Van De Mark, 2000 Thames et al., 2005). [Pg.584]
