The paper presents the information about biodamages and protection of leather and fur. The contributors put a special emphasis on rawhide microflora, putrefied hide microflora, effect of prior operations on bioresistance of leather, interesting facts, fur skin structure and properties changes by microorganisms and the methods of leather preservation against microorganism impact.
The paper is including information about classification and diagnostics of biodamages, raw materials, materials and products, biostability of materials evaluation methods and methods for material protection against biodamaging. The contributors are discussing the problems of biocides classification, application of antimicrobial materials, requirements to biocides and evaluation methods for antimicrobial properties of biocides
Requirements to properties of protective-technological coatings for the tin bronze melting from secondary raw materials were formulated in the work. The choice of model glasses compositions in the initial Na2O-B2O3-SiO2 system on the basis of the melting parameters values was made. Non-scarce and inexpensive raw materials for protective coatings were selected. Also the best glass composition was determined based on the complex of chosen properties. The formation mechanism of the selected composition glassy melting by using DTА and XRDА was studied.
