The hand lay-up or spray-up process, used universally for the production of laminar composites incorporating glass fiber reinforcement, is most efficient for the manufacture of large parts, such as boats, bathtubs, tanks, architectural shapes, and recreational accessories. Resins intended for spray-up processes are usually modified with thixotropic additives, such as fumed siHca (1%), to reduce the risk of drainage when appHed over large vertical mold surfaces. Molds are also made from ERP for short-mn products usually surfaced with a tooling gel coat to provide consistent surface quaHty and appearance. 

Design Features There are three classes of thickeners, each differentiated by its drive mechanism (1) bridge-supported, (2) center-column supported, and (3) traction drives. The diameter of the tank will range from 2 to 150 m (6.5 to 492 ft), and the support structure often is related to the size required. These classes are described in detail in the subsection Components and Accessories for Sedimentation Units. ... 

The cost of the filter station includes not only the installed cost of the filter itself but also that of all the accessories dedicated to the filtration operation. Examples are feed pumps and storage facihties, precoat tanks, vacuum systems (often a major cost factor for a vacuum filter station), and compressed-air systems. The dehvered cost of the accessories plus the cost of installation of filter and accessories generally is of the same order of magnitude as the dehvered filter cost and commonly is several times as large. Installation costs, of course, must be estimated with reference to local labor costs and site-specific considerations.

There are a wide range of applications that are made from SBC that may show up in the ordinary household. Some SBCs are used in appliances, housewares and office supplies. Owing to limitations of temperature resistance, chemical resistance, and abrasion resistance, the SBC may be blended with polymers such as styrene-methyl methacrylate (SMMA) to improve functionality. SBCs may also be seen in parts such as aquarium filter tanks, sewing machine dust covers, bird feeders, cake pan lids, pens, vacuum cleaners and computer accessories.

The chief items of cost in any suction conveyor system are the powerful exhaust fan required and the tank with its accessories in which the load handled is deposited and these essential appliances are just as costly for a short system as for a long one. The expense entailed for the conveyor duct, intakes, etc., varies, but for all practical purposes the cost of a complete system will be found to vary very nearly directly with its size, diameter of conveyor duct, or conveying capacity. The relative cost of a complete suction conveyor system is then expressed by the equation ...
