Resins bulk storage

This is used in manufacture of brake linings and is a polymer based on cashew nutshell liquid admixed with formaldehyde or furfuraldehyde and other ingredients. The polymerised resin mixture is cast into 8 cm thick slabs and then ground finely to produce the friction dust. Several fires have been experienced during bulk storage of the dust, attributed to autoxidation of the still partially unsaturated resin compound. Previously, linseed oil was used in place of the nutshell liquid, but fires were then more frequent. 

Grades of fiberglass that are resistant to methanol have been developed, primarily for use in bulk storage tanks. Fiberglass not designed for methanol will quickly soften and delaminate. Ford has reported that onboard fuel lines made of poly phenylene sulfide resin give good performance [3.6].

Since many amino resins contain solvents, local safety codes regarding flammable liquids should be observed. For bulk storage an inert gas atmosphere above the resin should be used [2.162],... 

Water soluble styrene acryHcs are processed via free radical polymerization in glycol ether solvents. The solvent is stripped by conventional or proprietary processes. Rosin based resins are processed molten at high temperatures up to 265 °C. These materials are flaked or pelletized and packaged in bags or bulk storage for further conversion. 

Wood shrinks on exposure to formaldehyde and for this reason is not entirely suitable for use in bulk storage, although properly constructed barrels ai e used. Formaldehyde solution in contact with wood may extract a small amount of resinous material and thus become discolored. If the solution is also in contact with iron or copper, deep colorations ranging from blue to black may result. This does not impair solution strength nor render it unsuitable for many ordinary uses. If discoloration is objectionable, exposure to these materials should be avoided. 

Storage. Phenol is shipped in dmms, tank tmcks, and tank cars. It is loaded and shipped at elevated temperatures as a bulk Hquid. In storage, phenol may acquire a yeUow, pink, or brown discoloration which makes it unusable for some purposes. The discoloration is promoted by the action of water, light, air, and catalysts, eg, traces of iron or copper. When stored as a solid in the original dmm or in nickel, glass-lined, or tanks lined with baked phenolic resin, phenol remains colorless for a number of weeks. 

In this solution, the volume of phenol-formaldehyde resin exceeds 1,250 million pounds per year. Most plywood adhesive resins are shipped in bulk quantities of 4,000 to 10,000 gallons via tankwagon or tankcar to the plywood mills and stored in storage tanks. Other ingredients are collected in a glue mix area and combined with adhesive resin. 

Shipment, Storage, and Price, Tank cars and tank trailers, selected to prevent color formation, are of aluminum or stainless steel, or lined with epoxy or phenolic resins drums are lined with phenolic resins. Flexible stainless steel hose is used for transfer. Because of butanediol s high freezing point (about 20°C) tank car coil heaters are provided. The U.S. list price for bulk quantities in 1991 was about 2.18/kg, but heavy discounting was prevalent for large contracts. 

Aromatic monoamines, having a minimum one additional functional group, and being found in the patent literature of poly(ester-imide)s, are the aforementioned p-aminobenzoic acid [48, 77], the p-aminophenol [78], the aminoth-erephthalic acid [79] and the p-aminobenzenesulfonic acid [80], but probably none of these monomers were ever used for large scale production. Also the di-aminobenzenes had no economical success as wire enamel raw materials, probably because they were too expensive, too toxic and because they have, in bulk, insufficient storage stability. 3,5-Diaminotriazole-(l,2,4) was claimed as raw material for wire enamel resin yielding films with improved hardness [81].

Liquid binders and oil products are delivered in drums, by bulk container or by road tanker. They are stored in their delivery containers or, in the case of rail tankers, discharged direct into a dedicated storage. The containers are connected by pipe directly to the sand/resin/catalyst-mixing unit. Some catalysts and co-reactants are used in a gaseous form, but these are also delivered as liquids and handled in a similar fashion before being vaporised and mixed with a carrier gas. Evaporation is enclosed and may be carried out by a variety of methods.

Processing plants which receive resin in bulk shipments require a considerable storage capability to hold their raw material inventory. Silos have been widely adopted to fill this requirement. In this section, we will examine the two basic methods of construction (bolted and welded) and look at the accessories required for a workable tank installation.
