Industrial growth rate

Worldwide growth in the adhesives market will reach 4% by 2004, again exceeding average industrial growth rates. 

The model assumes that only the two variables of relative market share and industry growth rate are necessary to establish the strategic position of a business. 

The apphcations of high purity gases are primary in the semiconductor industries. From 1991 to 1995, the North American semiconductor bulk gas sales increased from U.S. 214 to 252 million (aimual growth rate of 4.2%) and specialty gas sales increased from U.S. 78 million to 169 million (aimual growth rate of 21.4%). 

Acetic acid has a place in organic processes comparable to sulfuric acid in the mineral chemical industries and its movements mirror the industry. Growth of synthetic acetic acid production in the United States was gready affected by the dislocations in fuel resources of the 1970s. The growth rate for 1988 was 1.5%. 

In addition to their automotive use, PAO oils also find appfication in industrial and aircraft hydraufic fluids, gear oils, compressors, and environmentally sensitive appfications. They are also used in multipurpose greases for army, navy, nuclear, and industrial appfications. Expanding use has led to a growth rate of PAO production from 1985 to 1990 of 19% per year (28). 

The total production of the U.S. paper industry in 1994 was ca 85 million metric tons with a compound aimual growth rate over the previous decade of 2.7%. The domestic production of paper and board plus imports and minus exports maintains a remarkably constant ratio with real gross domestic product in the United States. One sector of the paper industry that has grown at a higher rate than GDP is recycled papers and boards which is projected to grow at 6.8% aimuaHy. Over one-half of paperboard production in the United States is from recycled fiber, and the industry as a whole is expected to achieve 50% recovery rate for paper and board products by the end of the twentieth century (see Recycling, paper). 

The term amino resin is usually appHed to the broad class of materials regardless of appHcation, whereas the term aminoplast or sometimes amino plastic is more commonly appHed to thermosetting molding compounds based on amino resins. Amino plastics and resins have been in use since the 1920s. Compared to other segments of the plastics industry, they are mature products, and their growth rate is only about half of that of the plastics industry as a whole. They account for about 3% of the United States plastics and resins production. 

In 1993, the United States medical device industry employed 282,000 people, averaging a growth rate of about 4% since 1975. Research and development spending in this industry outpaced that in virtually every other industry. Over 7% of sales were spent on research and development in 1993, amounting to a Httle less than 3 bHHon. This rate reflects both the rapid rate of innovation and short product life-cycle. Medical devices become obsolete far more rapidly than pharmaceuticals (qv), forcing companies continuously to be innovative. 

In 1993, nearly 36 million tons of paper were recovered in the United States, twice as much as in 1980 (54). Eor the first time, more paper was recovered in the United States than landfilled. As a result, 11 million fewer tons of paper were landfilled in the United States in 1993 than in 1987. This saved more than 69 X 10 m (90 x 10 yd ) of landfill space. In 1995, recovered paper accounted for 31.5% of the fiber used to manufacture 84.1 million metric tons of paper products (54). Annual capital spending for paper recycling projects from 1995 to the year 2000 is estimated to average 2 biUion (55). The American Eorest Paper Association (AE PA) estimates U.S. consumption of recovered paper will increase 4.9% per year through the year 2000, nearly twice the total paper industry capacity growth rate (56). Consumption of recovered paper in U.S. mills in 1997 is estimated at 35.6 million tons (57). 

Hard facing of various components in the aircraft gas-turbine engine and in industrial apphcations for textile machinery parts, oil and gas machinery parts, paper-shtting knives, etc, is estimated at 1 x 10 in 1995 with an estimated growth rate of 5% annually. The mix is approximately 45% aerospace apphcations, 55% industrial apphcations. Additionally, repair coatings for gas-turbine blades and vanes is estimated at 500 x 10 . These coatings are primarily deposited by plasma spray, arc-wire, HVOF, and detonation gun techniques. 

Consequendy, the figures of Table 7 are stiU appHcable to the present day. More recent independent reviews (27,28) indicate a slighdy lower wodd output of 750,000 to 800,000 t/yr. With the present state of the wodd economy in 1993 the growth rate for the industry is likely to be as low as 2—3%, but even this low figure represents something like an additional 20,000 t/yr. The major dye producing countries and companies in Western Europe are shown in Table 8. 

It is emphasized that the delta L law does not apply when similar crystals are given preferential treatment based on size. It fails also when surface defects or dislocations significantly alter the growth rate of a crystal face. Nevertheless, it is a reasonably accurate generahzation for a surprising number of industrial cases. When it is, it is important because it simphfies the mathematical treatment in modeling real crystallizers and is useful in predicting crystal-size distribution in many types of industrial crystallization equipment. 

In order to treat crystallization systems both dynamically and continuously, a mathematical model has been developed which can correlate the nucleation rate to the level of supersaturation and/or the growth rate. Because the growth rate is more easily determined and because nucleation is sharply nonlinear in the regions normally encountered in industrial crystallization, it has been common to...
