Bitstream created a library of "classic" fonts (usually under different names for trademark reasons) in digital form. For example, Times Ten was released as Dutch 801, Akzidenz-Grotesk as Gothic 725, Antique Olive as Incised 901, Bembo as Aldine 401, Berthold Block as Gothic 821, Bodoni Campanile as Modern 735, Choc as Staccato 555, Eurostile as Square 721, Frutiger as Humanist 777, Gill Sans ...
To create foam latex, a liquid latex base is mixed with various additives and whipped into a foam, then poured or injected into a mold and baked in an oven to cure.The main components of foam latex are the latex base, a foaming agent (to help it whip into a froth), a gelling agent (to convert the liquid foam into a gel), and a curing agent (to turn the gelled foam latex into a solid when baked).
Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, thus achieving suppression of the combustion. Firefighting foam was invented by the Moldovan engineer and chemist Aleksandr Loran in 1902. [1] The surfactants used must produce foam in concentrations of ...
Continuous foam separation is a chemical process closely related to foam fractionation in which foam is used to separate components of a solution when they differ in surface activity. In any solution, surface active components tend to adsorb to gas-liquid interfaces while surface inactive components stay within the bulk solution.
The formula was meant to be dissolved in water at the concentration of 9.0 g/L, giving a bath with pH = 1.5. It yielded a light gold color after 1 min, and a golden-brown film after 3 min. The average thickness ranged between 200 and 1000 nm. [6] Iridite 14-2 is a chromate conversion bath for aluminum.
Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...
Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes ...
[1]: 6 [2]: 4 [3] The foam "may contain more or less liquid [or solid] according to circumstances", [1]: 6 although in the case of gas-liquid foams, the gas occupies most of the volume. [ 2 ] : 4 The word derives from the medieval German and otherwise obsolete veim , in reference to the "frothy head forming in the glass once the beer has been ...
