Brass wire tables

Many methods are available for determining particle size in pharmaceutical practice, including microscopy, sieving, sedimentation, and determination of particle volume [19]. Sieve analysis with U.S. standard sieves is widely used to determine the particle size distribution based on powder weight. Sieves are classified according to the number of openings (Table 14) and are generally made of wire cloth woven from brass, bronze, or other suitable wire.

Overall this new process is very attractive and has several environmental advantages, if it could replace brass on steel tyre cords. Tests with silane-treated tyre cords are in progress. The authors proposed use of a new tyre cord without brass coating but with a zinc coating instead, as tyre cords without brass coating are difficult to manufacture (the brass lubricates the die in the final wire drawing process). The final zinc-plated cord is then passed through a silane bath and dried. Quite remarkable in this system is that the silane-based film does not impair the adhesion of brass to sulphur-cured compound. If the adhesion of a brass plated cord is mediocre, the silane process actually improves its performance, as shown in Table 6.1 [58].
