![]() It is through these openings in the surface that sound waves enter the body of the acoustic material and are absorbed. When painting acoustic materials, the painter should be very careful that the paint does not close up the acoustic surfaces perforations or fissures. The amount of absorption depends on the thickness of the porous material, the size and number of pores, and the frequency of the noise. Sound-absorbing materials are highly porous to increase their sound absorption qualities. construction depends a great deal on acoustic materials to act as sound containment or sound control, either in residential or commercial applications. Whilst most treatments are old and well established, in recent years there has been a growth in innovative products, which overcome difficulties with the old technologies, especially when making the treatments more visually acceptable to architects. Read moreĪcoustic materials are used to treat indoor and outdoor spaces to make speech intelligible, and places less noisy and more pleasant to be in. It will also help the readers to understand underlying surface phenomena and will enhance the reader's potential for solving critical formulation, evaluation and process problems. In addition, it will be a valuable reference source for both novices as well as experts in the field of waterborne technology. ![]() The editors hope that this volume will serve its intended objective of reflecting the current understanding of formulation and process problems related to waterborne coatings, paints and inks. This volume includes discussions of various waterborne polymers in coating!printing systems. These papers are divided in three broad categories: (1) Waterborne Polymers and pigment Dispersions, (2) Latex Film, Wetting Phenomena and Printing Gloss, (3) Surfactants and Polymers in Aqueous Coating!printing Systems. This edition includes sixteen selected papers related to recent developments in waterborne technology. Major topics discussed involve waterborne polymers and polymer blends, pigment grinding, millbases, paint formulation, and characterization of coating films. The volume deals with various basic and applied aspects of research on waterborne coating!printing technology. The FPS meeting was held in Las Vegas, Nevada, July 13-17, 1992. It documents several invited papers and the proceedings of the International Symposium on Surface Phenomena and Latexes in Waterborne Coatings and printing Technology sponsored by the. This is the third volume in the series on waterborne coating and printing technology. THE CURRENT STATE OF THE ART of waterborne polymers, paints, coatings, inks and printing processes is presented in this volume. It is expected that national industries can fulfill the paint requirements, code and standard as protection coatings on NPP components and can develop and produce paint that is resistant to radiation, chemicals and fire. From the result of the study it is concluded that if Indonesia builds nuclear power plant. The purpose of the study is to identify the requirements, codes and standards used for paint as protection coatings of nuclear power plants. The methodology used in this study is: 1) collecting articles and journals related to paint protection coatings for NPP components 2) reviewing requirements for the manufacture of paints as protection coatings of nuclear components 3) reviewing codes and standards required in the manufacture of paints as coatings protection. ![]() Paint Code and Standards requirements as a layer of protection of nuclear power plants refer to ASTM standards and some other standards. Potential safety impacts are a function of location within a plant that is divided into 3 levels: 1) Coating service Level I (CSL I), 2) Coating Service Level II (CSL II), 3) Coating Service Level III (CSL III). NPPs must use a strong protective coating and be able to meet the Accident Basic Design standard without affecting the safety related components required to reduce accidents. Paint coatings used in power plant should not contain lead, mercury, copper, cadmium, cobalt, antimony, chloride and fluoride more than 1%. ![]() The paint requirements should meet radiation resistance, ease of decontamination, chemical resistance, durability during operating conditions, durability during postulated post-injury conditions and fire resistance. Paint coatings are used on nuclear power plants to protect the surface of facilities and equipment to avoid corrosion, cracks, material degradation and contamination of radionuclides and for protection during plant operation and maintenance activities. The Paint is used to coat concrete and steel in Nuclear Power Plant (NPP) and other components.
