Products and Properties

Theoretically, an almost infinite number of different grades can be produced in a high-pressure polyethylene plant, due to the high flexibility in polymerization conditions and the relative short transition times. In contrast to the lo v-pressure technology, where the polymerization is carried out by Ziegler/Natta, chromium, or metallocene catalysts, the high-pressure process can also use polar comonomers such as vinylacetate, acrylic acid, or N-butylacrylate to modify product properties. With all these opportunities, the resin producer can adjust the product portfolio to cover the market needs at the current economic environment. LDPE homopolymer resins with densities 0.917-0.934 g/cm at MFRs 0.15-100 g/10 min are available in the market.

Paper Production and Properties. During the paper production process, the wood pulp is mixed into an aqueous slurry, which is poured onto a continuously moving wire mesh and drained by gravity. Additional water is then squee2ed out of the paper by a felt web pressed from above. This pressed side, referred to as the felt side, has smaller, finer fibers and is therefore smoother. It is also the preferred printing side.

Titanium dioxide (E171, Cl white 6) is a white, opaque mineral occurring naturally in three main forms rutile, anatase, and brookite. More than 4 million tons of titanium dioxide are produced per year and it is widely used for industrial applications (paints, inks, plastics, textiles) and in small amounts as a food colorant. ° "° Production and properties — Titanium oxide is mainly produced from ilmenite, a titaniferous ore (FeTiOj). Rutile and anatase are relatively pure titanium dioxide (Ti02) forms. Titanium oxide pigment is produced via chloride or sulfate processes via the treatment of the titanium oxide ore with chlorine gas or sulfuric acid, followed by a series of purification steps. High-purity anatase is preferred for utilization in the food industry. It may be coated with small amounts of alumina or silica to improve technological properties.

It should be noted that, to produce a reasonably monodis-perse spray, the liquid flow rate should be maintained at an extremely low level, and thus the scaling up of such devices may pose some difficulties. It is also rather difficult to assess the liquid flow rate that can be achieved due to few quantitative studies and lack of comprehensive understanding of the underlying principles. Another drawback of the electrostatic atomization technique is that both the production and properties of droplets are significantly dependent on the electrical properties of the liquid, limiting the type of liquids that can be successfully atomized. 

Reactive incidents primarily cause onsite impacts, such as worker fatalities and injuries-and severe business impacts, including lost production and property damage. However, a significant number of incidents have led to public impacts,29 which include public harm (injury or fatality), offsite evacuation, or shelter-in-place. Nearly 50 of the 167 incidents in the CSB data affected the public. At least eight of the 12 reactive incidents listed in Table 2 had public impacts. One of these incidents (CSI) resulted in a public fatality.

The production and properties of ethylene homo- and copolymer foams with densities less than 50 kg/cu.m. are reviewed. A brief historical summary is given, followed by a discussion of six key parameters as they relate to the properties and form of the foam. The diversity of the manufacturing processes available for foam production is illustrated by three distinct operating techniques. Stress-strain curves are used to demonstrate the wide spectrum of properties obtainable and examples of applications are given. 11 refs. 

The fourth state of matter, the plasma state , although rarely found at the surface of the earth, is the most commonly found state of matter when the known universe is considered. The plasma state, consisting of a neutral collection of electrons and positive ions, may have a very wide range of densities. The production and properties of this state are described. 

The National Highway Traffic Safety Administration estimates that over 200,000 automobile crashes are caused by drowsy drivers every year, resulting in over 1,500 deaths, 70,000 injuries, and an estimated 12.5 billion in lost productivity and property loss. The National Sleep Foundation s 2002 Sleep in America poll showed that over half of Americans said they have driven while feeling drowsy, and approximately 17% said they had actually fallen asleep while driving. ... 

Thus far, we ve discussed the sources, production, and properties of some important metals. Some properties, such as hardness and melting point, vary considerably among metals, but other properties are characteristic of metals in general. For instance, all metals can be drawn into wires (ductility) or beaten into sheets (malleability) without breaking into pieces like glass or an ionic crystal. Furthermore, all metals have a high thermal and electrical conductivity. When you touch a metal, it feels cold because the metal efficiently conducts heat away from your hand, and when you connect a metal wire to the terminals of a battery, it conducts an electric current.

Acrylic fibers (PAC) are, together with PES and PA, the most important synthetic fibers [154], For methods of production and properties of PAC fibers see [96, pp. 629-642], To obtain fibers with satisfactory dyeing properties, anionic comonomers are used. In this way, the glass transition temperature Tg is lowered and anionic groups are available that can act as dye sites for cationic dyes. Thus, acrylic fibers are reliably and economically dyeable wth cationic dyes.

In a previous publication in this series (8), Hagemeyer set alkaline papermaking in the context of future demand for paper, and dealt briefly with some of the technical consequences. Since then, more mills have converted to the new method, and the aim of this chapter is to inform the reader in some detail about the reasons for changing to neutral/alkaline papermaking, some of the consequences for the production and properties of paper, and how the change impinges on...
