Fiberglass composite boats have been made since the early 1940s, [20] and many sailing vessels made after 1950 were built using the fiberglass lay-up process. As of 2022, boats continue to be made with fiberglass, though more advanced techniques such as vacuum bag moulding are used in the construction process.
Deoxidization is a method used in metallurgy to remove the rest of oxygen content from previously reduced iron ore during steel manufacturing. In contrast, antioxidants are used for stabilization, such as in the storage of food.
[34] [35] The staining properties of sunblock made with avobenzone are particularly noticeable on fiberglass boats with white gelcoat. [citation needed] Avobenzone also reacts with boron trifluoride to form a stable crystalline complex that is highly fluorescent under UV irradiation.
Fluxes are also used in foundries for removing impurities from molten nonferrous metals such as aluminium, or for adding desirable trace elements such as titanium. As reducing agents, fluxes facilitate soldering, brazing, and welding by removing oxidation from the metals to be joined. In some applications molten flux also serves as a heat ...
Textile fiberglass is used to reinforce plastics in applications that range from boats, to industrial piping to computer circuit boards. [33] In the jewelry industry, boric acid is often used in combination with denatured alcohol to reduce surface oxidation and formation of firescale on metals during annealing and soldering operations. [34] [35]
Police also promoted a program that helps boat owners remove their damaged vessels from the water at no cost.
In-water cleaning, also known as in-water surface cleaning, is a collection of methods for removing unwanted material in-situ from the underwater surface of a structure.. This often refers to removing marine fouling growth from ship hulls, but also has applications on civil engineering structures, pipeline intakes and similar components which are impossible or inconvenient to remove from the ...
Weld purging is the act of removing, from the vicinity of the joint; oxygen, water vapour and any other gases or vapours that might oxidize or contaminate a welding joint as it is being welded and immediately after welding.
