Glass-fiber reinforced plastic

Liquid polyalurninum chloride is acidic and corrosive to common metals. Suitable materials for constmction of storage and handling facilities include synthetic mbber-lined steel, corrosion resistant fiber glass reinforced plastics (FRP), ceramics, tetrafluoroethylene polymer (PTFE), poly(vinyhdene fluoride) (PVDF), polyethylene, polypropylene, and poly(vinyl chloride) (PVG). Suitable shipping containers include mbber-lined tank tmcks and rail cars for bulk shipment and plastic-lined or aH-plastic dmms and tote bins for smaller quantities. Except for aluminum chlorohydrates, PAG products are shipped as hazardous substances because of their acidity. 

DynaWave equipment is typicaUy smaller than conventional equipment and is usuaUy made of fiber glass reinforced plastic (ERP) at considerable capital savings over conventional materials. DynaWave is now in use at a number of plants worldwide. 

Most metals, concrete, and other constmction materials are corroded by hydrobromic acid. Suitable materials of constmction include some fiber glass-reinforced plastics, some chemically resistant mbbers, PVC, Teflon, polypropylene, and ceramic-, mbber-, and glass-lined steel. Metals that are used include HasteUoy B, HasteUoy C, tantalum, and titanium. The HasteUoys can only be used at ambient temperatures. Liquid hydrogen bromide under pressure in glass at or above room temperature can attack the glass resulting in unexpected shattering.

Experimental research was performed on models of reinforced concrete beams (10 x 20 x 120 cm) with polymeric concrete layers. B 25 class concrete was used main longitudinal reinforcement of A-III class was used in the form of two 8-mm diameter rods and the 5-mm diameter stirrups of the same class arranged, so that destruction would be along normal sections. Epoxy-rubber compositions were used as covering layer materials. All compositions were made on ED-20 epoxy-based resin. Besides fiber glass-reinforced plastic glued by ED-20 compositions based on liquid rubbers, RubCon was used. The composition of the polymer layers and some of their mechanical characteristics are given in Table 6.3. 

While the previously described three membrane modules required flat sheet membrane material for their preparation, special membrane configurations are needed for the preparation of the tubular, capillary, and hollow fiber modules. The tubular membrane module consists of membrane tubes placed into porous stainless steel or fiber glass reinforced plastic pipes. The pressurized feed solution flows down the tube bore and the permeate is collected on the outer side of the porous support pipe, as indicated in Figure 1.33 (d). The diameters of tubular membranes are typically between 1-2.5 cm. In some modules, the membranes are cast directly on the porous pipes and in others they are prepared separately as tubes and then installed into the support pipes.

Quenching reduces the volume of gas leaving the furnace, allowing smaller equipment to be used downstream. The temperature downstream of a quench tank is maintained below about 185°F (85°C) allowing less-expensive and more-corrosion-resistant materials such as fiber glass-reinforced plastic to be used in the scmbbing system and stack. 

Many filler materials are treated chemically to improve the adhesion between the filler and resin. The most widely known of these treatments are used on glass fibers and include silane reaction products and chromium complexes. Glass fibers are often flame treated. Several of the treatments are summarized in Table 3-3. Improved versions of these treatments have resulted in major improvements in the performance of fiber glass reinforced plastics so that a large fraction of the potential strength of these materials is realized in practice.
