Brown goods

Appliances may be classified into three major types white goods, brown goods, and traffic appliances. White goods are primarily those products associated with laundry and refrigeration such as washers, dryers, dishwashers, ranges, refrigerators, and freezers. The name was due to the primary use of white for these products. Brown goods Include radios, television sets, furnaces, air conditioners, and home entertainment products, while traffic appliances include toasters, mixers, electric knives, fans, blenders, and other more portable items. 

Materials, like ABS and HIPS are widely used as housings for brown goods, IT and business machines. Unfortunately they bum easily but can be protected by the correct use of flame retardant science and technology. The starting point has always been to use brominated FRs plus antimony oxide as a synergist. However, these long-standing products do not often meet all of the requirements. 

The major location of the BFRs is in business, data processing and telecomms equipment at 53% of EEE using BFRs. Brown goods have 22%, industrial items a further 7%, household ones just 2%... 

Polymers, including PP, are widely used in other consumer electrical goods, such as brown goods and the home computer market. These will not be included in this chapter and the focus will be on household appliances and white goods. 

Brown goods TV sets, VCR, DVD players, audio equipment.

The solid readily dissolves chemically in concentrated hydrochloric acid, forming a complex, and in ammonia as the colourless, linear, complex cation [H3N -> Cu <- NHj] (cf AgCl) if air is absent (in the presence of air, this is oxidis to a blue ammino-copper(II) complex). This solution of ammoniacal copper(I) chloride is a good solvent or carbon monoxide, forming an addition compound CuCl. CO. H2O, and as such is used in gas analysis. On passing ethyne through the ammoniacal solution, a red-brown precipitate of hydrated copper(I) dicarbide (explosive when dry) is obtained ...

Bakery Products. Sorbates are used in and/or on yeast-raised and chemically leavened bakery products. The internal use of sorbates in yeast-raised products at one-fourth the amount of calcium—sodium propionate that is normally added provides a shelf life equal to that of propionate without adversely affecting the yeast fermentation. Sorbates added at one-tenth the propionate level reduce the mix time by 30% (126). This internal treatment combined with an external spray of potassium sorbate can provide the same or an increased shelf life of pan breads, hamburger and hot-dog buns, English muffins, brown-and-serve roUs, and tortillas. The total sorbate useful in or on these baked goods ranges from 0.03 wt % for pan breads to 0.5 wt % for tortillas 0.2—0.3 wt % sorbic acid protects chemically leavened yellow and chocolate cakes (127). Emit-pie fillings and icings can be protected with 0.03—0.1 wt % sorbates. 

In dyehouses where sulfide effluent is a problem, sulfur dyes of good chlorine fastness that dye satisfactorily from a dithionite—caustic alkaU bath offer an advantage. Included in this group are Cl Sulfur Black 11, Cl Sulfur Red 10 [1326-96-1] (Cl 53228), Cl Sulfur Brown 96 [1326-96-1] (Cl 53228), Cl Vat Blue 42, and Cl Vat Blue 43. The shades of these dyes can be brightened by the addition of vat dyes thus increasing the fastness of the resulting dye. 

Metallurgical (smelter) plants and spent acid decomposition plants usually produce acid of good (low) color because the SO2 feed gases ate extensively purified prior to use. In some cases, however, and particularly at lead smelters, sufficient amounts of organic flotation agents are volatilized from sulfide ores to form brown or black acid. Such acid can be used in many applications, particularly for fertilizer production, without significant problems arising.
