Chlorinated rubber paints production

Figure 1 indicates a typical nitroglycerin facility "inside out" wood frame construction at a concrete floor slab. Note that the exterior cant strip, the lead conductive floor cant and the wood cap are all sloped to discourage product build-up and facilitate cleaning. This assembly also indicates spray-on foam insulation as an optional construction item. At Radford AAP this is a safety approved insulation system. The insulation at Radford AAP received a chlorinated rubber paint coating for weathering. 

Production corresponds to that of pure chlorinated rubber paints (see Section 2.3.2). 

Diisopropyl ketone [565-50-0] (DIPK, 2,4-dimethyl-3-pentanone) is a high-boiling solvent used in the production of cellulose nitrate emulsion lacquers for coating leather, chlorinated rubber paints, and diluents for poly(vinyl chloride) organosols [14.267]. 

Interannual changes in production of total chlorinated paraffins (CPs) reported by the Flame Retardant Chemicals Association of Japan (FRCJ) [2] are shown in Fig. 2. FRCJ also reported the production and shipment of SCCPs, medium-chain chlorinated paraffins (MCCPs), and long-chain chlorinated paraffins (LCCPs) in 2001 [2] as shown in Table 1. It indicates that 500 tons per year of SCCPs were shipped, suggesting that SCCPs were not used for polyrvinyl chloride. In the Kanto region, 500 tons per year of SCCPs were mainly used in oil fluids. In contrast, nearly 200 tons of SCCPs were shipped to the Kansai region for other uses including flame retardant additives and lipid additives for rubber, paint, and adhesives. As shown in Table 1, approximately half of SCCPs were used in oil fluids and the other half for other products. 

Before the challenges that face the industry can be reasonably discussed, the industry itself must be defined. Specific statistics that give adequate comparisons on sales, pounds, and total value of synthetic organic chemicals sold are not easy to determine, and it becomes necessary to define the industry by a process of elimination. The United States Department of Commerce reports that the aggregate of sales among chemicals and allied products accounted for about 23 billion in 1957. In Table I, it can be seen that almost 18 billion of this aggregate were accounted for by finished product sales synthetic rubber, paints, soaps, fertilizers, and pharmaceuticals or by inorganic chemicals such as sulfuric acid, ammonia, and chlorine. 

Dimethylacetal [534-15-6] (acetaldehyde dimethyl acetal, 1,1-dimethoxyethane) is a neutral liquid that is miscible with water and organic solvents. It dissolves cellulose nitrate, cellulose ethers, poly(vinyl acetate), polyacrylates, polymethacrylates, poly(vinyl ethers), some vinyl chloride copolymers, and synthetic and natural resins. It does not dissolve poly(vinyl chloride), polystyrene, chlorinated rubber, and cellulose acetate. It is used in the production of paints, adhesives, and shoe-cap stiffeners. 

Plasticized, it produces a film highly impermeable to water and water vapor. Chlorinated rubber is chiefly used in the production of heat- and chemical-resistant paints, varnishes, and lacquers. Films, impregnating solutions, adhesives, and (with the addition of plasticizers) molding powders can also be made. 

Chlorinated Rubber (rubber chloride) (1) Natural rubber in which about two-thirds of the hydrogen atoms have been replaced by chlorine atoms. The resin is formed by the reaction of rubber with chlorine at about 100° C in an inert solvent or as a latex. UnHke rubber, the resulting product is readily soluble and yields solutions of low viscosity. It is sold as white powder, fibers, or as blocks. Commercial products generally contain about 65% chlorine. It has good chemical resistance properties, however, it tends to cobweb when sprayed. Now mostly chlorinated polymers are used, as 1-butene, polyethylene, etc. It has adhesive properties and, because of its good fire resistance, is used in paints. (2) Chlorinated natural rubber. Manufactured by Bayer, Germany. 

A white fibrous product obtained when chlorine is passed into a solution of rubber. It was used mainly in corrosion-resistant paints and varnishes but has been superseded by tailored synthetic polymers systems. 

The transformation of raw materials into products of greater value by means chemical reaction is a major industry, and a vast number of commercial prod is obtained by chemical synthesis. Sulfuric acid, ammonia, ethylene, propyl phosphoric acid, chlorine, nitric acid, urea, benzene, methanol, ethanol, ethylene glycol are examples of chemicals produced in the United States, billions of kilograms each year. These in turn are used in the large-scale manu ture of fibers, paints, detergents, plastics, rubber, fertilizers, insecticides, Clearly, the chemical engineer must be familiar with chemical-reactor design operation. 

Epichlorohydrin is usually prepared from propene and is mainly used in the manufacture of glycerol and epoxy resins. It is also used in the manufacture of elastomers, glycidyl ethers, cross-linked food starch, surfactants, plasticizers, dyestuffs, pharmaceutical products, oil emulsifiers, lubricants, and adhesives as a solvent for resins, gums, cellulose, esters, paints, and lacquers and as a stabilizer in chlorine-containing substances such as rubber, pesticide formulations, and solvents. 

MAJOR USES Used in the manufacture of carbon tetrachloride, trichloroethylene, chlorinated hydrocarbons, polychloroprene, polyvinylchloride, hydrogen chloride, hypochlorous acid, ethylene dichloride, metallic chlorides, chlorobenzene, chloroacetic acid, chlorinated lime, chloroform Used in the manufacturing process of water purification, flame retardant compounds, paper products, textiles, petroleum products, medicines, antiseptics, insecticides, solvents, paints, plastics, disinfectants, synthetic rubber. 

Chlorosulphonated polyethylene (CSM). A synthetic rubber produced by reacting polyethylene with chlorine and sulphur dioxide. Its products have good weather resistance even in light colours. Applications technical rubber goods, roofing sheets, fabric coatings, film-forming component in lacquers and paints. Trade name Hy-palon (USA). 

Chlorine is also used in the production of many inorganic chemicals. The major product is titanium dioxide, which is made by reacting rutile (92-96% 1102) or a mixture of ilmenite (40-55% TiOi) and rutile with chlorine to fomi HCU which is then purified and oxidized to Ti02. 1102 is used as a pigment for paints, paper, plastics, and rubber.
