Protective articles

The Environmental Protection Law is a comprehensive law on environmental protection. Article 33, which is directly related to management of POPs, states, The production, storage, transportation, sale and use of toxic chemicals and materials containing radioactive substances must comply with the relevant state provisions so as to prevent environmental pollution. In addition, the Law on the Prevention and Control of Water Pollution, the Law on the Prevention and Control of Air Pollution, the Marine Environment Protection Law, the Law on Environmental Impact Assessment, and the Law on the Prevention and Control of Environmental Pollution by Solid Wastes have all put forward pollution prevention requirements. Previous experience can also be used in the management of POP-like materials. Presently, China has no laws that specifically address management of POPs.

ACFs have been successfully applied in many fields, such as the treatment of organic and inorganic waste gases, the recovery of organic solvent, air cleaning and deodorization, treatment of wastewater and drinking water, separation and recovery of precious metals, as medical adsorbents and protective articles, and in electrodes [57], Some of the most common applications of ACF are listed below Table 8.2. 

European Commission Directorate-General for Energy, Directorate D - Nuclear Energy Radiation Protection, Article 35 Technical Report, Institute of Isotopes, Budapest, Hungary, HU-12/01, 6 to 8 March 2012. 

There are only two commercially important water-borne polymers currently used by the dipping industry and both are used to manufacture hand-protection articles. These polymers are ... 

As stated earlier ethylene-propylene elastomers are sensitive to light and UV rays. If the compound is black then the carbon black will act as an absorber and can protect articles from the effects of daylight exposure for decades. 

This article presents methods of synthesis and objective control of special flat optical elements (computer-synthesized holograms) as elements of protection. Due to the limited number of pages, we cannot go into great detail to explain the technology of how computer-synthesized holograms are created. The goal of this publication is to discuss following subjects ...

Packaging constitutes another significant use and is often a foam-ia-place operation to protect iadustrial equipmeat such as pumps or motors. Furniture articles molded from rigid foam are used in the form of decorative drawer fronts, clock cases, and simulated wooden beams. Flotation for barge repair and sport boats as well as insulation for portable coolers are a few other uses. 

This article provides a basic, step-by-step approach to problem solving in the practice and management of patents and trade secrets. The significance of aggressive patent and trade secret protection to the economic well-being of a business or organization should not be underestimated. Without patents and trade secrets, the marketplace is reduced to competition on the basis of price, which may be very difficult. 

Polyamides, like other macromolecules, degrade as a result of mechanical stress either in the melt phase, in solution, or in the soHd state (124). Degradation in the fluid state is usually detected via a change in viscosity or molecular weight distribution (125). However, in the soHd state it is possible to observe the free radicals formed as a result of polymer chains breaking under the appHed stress. If the polymer is protected from oxygen, then alkyl radicals can be observed (126). However, if the sample is exposed to air then the radicals react with oxygen in a manner similar to thermo- and photooxidation. These reactions lead to the formation of microcracks, embrittlement, and fracture, which can eventually result in failure of the fiber, film, or plastic article. 

In rare instances it is possible to sterilize an article at the time and place of its use. However, steriliza tion generally takes place at one location prior to use of an article at another location. The main purpose of packaging (qv) is to protect the stetiHty of the contents. When an article is placed in its protective container and subsequentiy sterilized, the process is called terminal sterilization. When it is sterilized first and then placed in a presterilized container, the process is called sterile filling. 

In devising strategies to prevent insect attack on processed woolens, it is appropriate to aim only to protect processed wool goods and to control the principal domestic pest species. This is usually achieved by incorporation of an insecticide into those goods required to be protected, usually from the dyebath while the articles are being dyed, and methods for protection of wool goods have been reviewed (122). 

The required extent of durabiUty depends on the use of the treated article. For example, an antistatic finish that is removed after several launderings would be termed nondurable for blankets to be used in hospitals and motels where static protection through over fifty launderings is desirable. However, the same finish appHed to blankets for household use which would be laundered once or twice per year could be termed durable. Antistatic finishes have been widely reviewed (73—75,77,86,90—95). 

Barrier polymers are used for many packagiag and protective applications. As barriers they separate a system, such as an article of food or an electronic component, from an environment. That is, they limit the iatroduction of matter from the environment iato the system or limit the loss of matter from the system or both. In many cases the environment is simply room air, but the environment can be very different, such as ia the case of protecting a submerged system from water.
