This book is devoted to a nontraditional class of materials which are manufactured by the melt-blowing process - i.e. by extrusion of polymer melt followed by fiber stretching with a gas stream. For the first time extensive data on classical and modern modifications of this technology are generalized and a review is given of extrusion head dies and subsidiary equipment. The text examines the structure and main properties of melt-blown materials as conditioned by peculiarities of overheated polymer melt spraying in an oxidizing medium. Information is given about filtering mechanisms and the...

One of the key problems of failure-free operation of machinery is prevention of corrosion. The global scale of modern production makes this problem even more critical. At the beginning of the 21st century industrial contami- tion and the corrosion-active nature of the environment reached a level such that corrosive damage of materials became commensurate with their prod- tion volume and expenditure on anticorrosion protection of machines became comparable with investments in basic production. Anticorrosion techniques changed from being an auxiliary service to industrial enterprises into a...

The objective of the book is to present a new understanding of the joint functioning as an "intelligent" friction assembly and of the biophysical mechanisms of interaction of synovial fluid with joint tissues through the electromagnetic biofield of the joint. These ideas have served the basis for the methodology of transfusion chondroprotection of synovial joints. Its main propositions and first encouraging results of clinical application are discussed in this book. The book can be of interest to orthopedists, physiologists, biophysists, and specialists in material science and tribology.

Kniga posvyashchena razrabotke upakovochnykh polimernykh plenok, otkhody kotorykh uskorenno razrushayutsya pochvennymi mikroorganizmami. Otlichitel'naya osobennost' razrabatyvaemykh plenok sostoit v tom, chto oni yavlyayutsya elektretami, t.e. elektricheski polyarizovany i dlitel'no sokhranyayut polyarizatsionnyy zaryad. Postoyannoe elektricheskoe pole, sozdavaemoe elektretnymi plenkami s poverkhnostnoy plotnost'yu zaryada 4-8 nKl/sm kv., yavlyaetsya faktorom, privlekayushchim pochvennye mikroorganizmy. Eto obuslovlivaet ikh uskorennuyu immobilizatsiyu na plenochnykh otkhodakh i...
