Найти книгу: "Additives for Coatings"

No doubt: A perfect coating has to look brilliant! But other properties of coatings are also most important. Coatings have to be durable, tough and easily applicable. Additives are the key to success in achieving these characteristics, even though the amounts used in coating formulations are small. It is not trivial at all to select the best additives. In practice, many series of tests are often necessary, and the results do not explain, why a certain additive improves the quality of a coating and another one impairs the coating. This book is dedicated to developers and applicants of coatings working in research or production, and it is aimed at providing a manual for their daily work. It will answer the following questions: How do the most important groups of additives act? Which effects can be be achieved by their addition? Scientific theories are linked to practical applications. Emphasis is put on the optical aspects that are most important for the applications in practice. This book is a milestone in quality assurance in the complete field of coatings!

Describes twenty-one of the most important and commonly used additives A Concise Introduction to Additives for Thermoplastic Polymers focuses on additives for thermoplastic polymers and describes 21 of the most important and commonly used additives from Plasticizers and Fillers to Optical Brighteners and Anti-Microbial additives. It also includes chapters on safety and hazards, and prediction of service time models. While there are many exhaustive and complex books dealing with additives for polymers, the size of them deter students and many industry engineers from using them. The purpose of this book, therefore, is to fill this void and present a concise introduction to this important subject. Written in an accessible and practical style, the author introduces the reader to the complex subject of plastics additives in an engaging manner. His ability to be concise is the result of his teaching courses on the subject and using his own lecture notes for material. This book comprises the author's course notes so that a larger public can benefit from his knowledge. A Concise Introduction to Additives for Thermoplastic Polymers is the ideal primer for students who will later work in polymer science or the development of plastics formulation, as well as industry engineers and specialists who want to have a deeper knowledge of the plastics industry.

It is intended that the book will be a practical guide to provide any reader with the basic information to help them understand what is necessary in order to produce a good barrier coated web or to improve the quality of any existing barrier product. After providing an introduction, where the terminology is outlined and some of the science is given (keeping the mathematics to a minimum), including barrier testing methods, the vacuum deposition process will be described. In theory a thin layer of metal or glass-like material should be enough to convert any polymer film into a perfect barrier material. The reality is that all barrier coatings have their performance limited by the defects in the coating. This book looks at the whole process from the source materials through to the post deposition handling of the coated material. This holistic view of the vacuum coating process provides a description of the common sources of defects and includes the possible methods of limiting the defects. This enables readers to decide where their development efforts and money can best be used to improve the barrier performance of their own process or materials. The 2nd edition contains at least 20% new material including additional barrier testing techniques that have been developed and testing and cleaning equipment brought to market since the 1st edition was published in 2010. The topic of adhesion is covered in more detail and there is a section on the Hanson Solubility Parameter which is a method of predicting the solubility of gases or liquids in materials.

The Chemistry of Food Additives and Preservatives is an up-to-date reference guide on the range of different types of additives (both natural and synthetic) used in the food industry today. It looks at the processes involved in inputting additives and preservatives to foods, and the mechanisms and methods used. The book contains full details about the chemistry of each major class of food additive, showing the reader not just what kind of additives are used and what their functions are, but also how they work and how they can have multiple functionalities. In addition, this book covers numerous new additives currently being introduced, and an explanation of how the quality of these is ascertained and how consumer safety is ensured.

“Plastics Additives and Testing” is a practical book for engineers and operators and discusses both inorganic and organic chemicals that are widely used as additives in plastics processing operations. It is common practice today to use analytical techniques to improve plastics processing. Because it is critically important to manufacture quality products, a reasonable balance must be drawn between control requirements and parameters for improved processing method with respect to plastics additives. This book serves to implement this balance in the manufacturing line. Written by a successful, international consultant with an excellent publishing track record, it combines plastics additives, testing and quality control and is a valuable and critical book for engineers and operators to have when performing their tasks.

The use of additives in food is a dynamic one, as consumers demand fewer additives in foods and as governments review the list of additives approved and their permitted levels. Scientists also refine the knowledge of the risk assessment process as well as improve analytical methods and the use of alternative additives, processes or ingredients. Since the first edition of the Food Additives Databook was published, there have been numerous changes due to these developments and some additives are no longer permitted, some have new permitted levels of use and new additives have been assessed and approved. The revised second edition of this major reference work covers all the «must-have» technical data on food additives. Compiled by food industry experts with a proven track record of producing high quality reference work, this volume is the definitive resource for technologists in small, medium and large companies, and for workers in research, government and academic institutions. Coverage is of Preservatives, Enzymes, Gases, Nutritive additives, Emulsifiers, Flour additives, Acidulants, Sequestrants, Antioxidants, Flavour enhancers, Colour, Sweeteners, Polysaccharides, Solvents. Entries include information on: Function and Applications, Safety issues, International legal issues, Alternatives, Synonyms, Molecular Formula and mass, Alternative forms, Appearance, Boiling, melting, and flash points, density, purity, water content, solubility, Synergists, Antagonists, and more with full and easy-to-follow-up references. Reviews of the first edition: «Additives have their advantages for the food industry in order to provide safe and convenient food products. It is therefore essential that as much information as possible is available to allow an informed decision on the selection of an additive for a particular purpose. This data book provides such information – consisting of over 1000 pages and covering around 350 additives. This data book does provide a vast amount of information; it is what it claims to be! Overall, this is a very useful publication and a good reference book for anyone working in the food and dairy industry.» —International Journal of Dairy Technology, Volume 59 Issue 2, May 2006 «This book is the best I have ever seen … a clear winner over all other food additive books .... a superb edition.» —SAAFOST (South African Association for Food Science and Technology)
