Materials  Sulphurous heat settings of PVC
PVS is one the most common used polymer in the world. One of the most problem making hardships to the polyvinylchloride processing is its thermal instability. Therefore, it shall proceed to PVC processing after its stabilization only. The effective stabilizing systems introduction allows to increase the induction period greatly. Here is sited the analysis of different PVC stabilizers using in the article. As established, the specimens possessing quite high thermally stabilize activity relatively PVC, were exposed among amides and minosuphyth acids. Such thermally stabilizing agents may prove be perspective for PVC packing materials production for a food oiling agents and fat-containing products. Biodegradable polymeric package The wide using of polymers for a package production besides its great preferences has some disadvantages also. One of them is the ecological problem solution difficultness. This solution may be biodegradable polymeric materials production. The production analysis and three groups of biodegradable polymeric materials using are given in the article. These materials are widely used with packing means production in West Europe and North America. However, there are no wide perspectives of biodegradable materials using in CIS countries yet. Polyvinylacetate glues It is observed, during the last years, the great rise of PVA glue using mainly for glues and dyes production. The most used glue is a polyvinylacetate dispersion. Glues are made on the PVA glue base are used by packing industry automatic lines for a cardboard wrapper production and to production of multy-layer paper bags, fiber drams, combined materials, envelopes and so on. It is may be obtained a quantities of production types with the copolymerization way, possessing input properties. Here is cited examples of PVA glue using in the national economy different fields and the exchanging methods of its physical - mechanical properties in the article. Even the present day, the glue remains quite perspective and actual item. Technology  PETF package using and its hygienic characteristic
Along with the wide using of polymers different types as packing materials, for the last 10 years PETP has a wide using also. The polymer is produced as films, fibers or complete products usually. It is known the equipment samples whereby the complete product packing process is made. Along with the mentioned above it is known that under the accordant conditions (temperature, pressure) PTEP destruction may happens and as a result the foodstuffs contamination with toxic agents. Results of different PETP items hygienic researches in contact with model environments, which imitate foodstuffs, are given in the article. It has been ascertained that thermo and chemical stable PETP package is ecologically clean for many foodstuffs packing and storage.
Projection of transport and technological packing systems The undisturbed and quality operations ensuring of highly productive automatic lines requires the detailed projection of not only all technological process elements and the correspondent tests of all transport process elements. The coordination necessity of the technological operations execution time with production transportation operations makes demands of comprehensive approach to the projection of technological and transportation processes, so that the projection of transport and technological packing devices. In the article is given the transportation process structure as the consecution of typical transport operations. Along with it, we will carry out the classification and enciphering of transport operations on transport and technological systems three elements interaction - an article, packing machine and tangible flow.
Drastic change pressure technologies using in package technologies
The vacuum technologies for foods packing found wide using during the last period. The production vacuum treatment, as a rule, is accompanied with a power action. For all that, it is not in mind the power is spent to the vacuum creating peculiarly, and to the biological system conversion to its new thermodynamic state. The thermodynamic parameters changing speed under a vacuumization may be compared with scopes of quite limited physical treatments parameters quantities. In the article is given a comparative analysis of power affect methods to biological systems, and as a result the confirmation of drastic change pressure technologies availability in packing technologies. Compaction of loose production in the consumer package With the loose production transportation from a producer to consumer, its packing is carried of the dynamical and static loads. As a result, the transported production is compacted that leads to its volume decreasing and to the empty volume extension between the production and the package body. These effects lead to the package integrity destruction and its appearance attractiveness losing. For the problem partial dissolving it is installed the vibrating systems in the packing equipment. It allows to compact a product and fill up the package almost completely. Here is, in the article, sited the vibrating systems researches results, which provide the effective loose products compaction for different rheological groups. Influence of a construction closing of a node On impermeability of canning tare The virtues and deficiencies of different types of corking of tare from a point of view of the producer of tinned yields and customer are analysed. The analysis of influence is intense is deformed states of devices closing of a node on origin of imperfections in tare is carried out. Is shown, that at development of new types of tare with given volume it is necessary to diminish a diameter D and to augment height (Í/D 1,1…1,5), and also to diminish magnitude of a sag of a cover, to augment a rigidity of a housing of metal tare in a place of a running together of a cover, to develop such profile of a contour of covers, which would eliminate an opportunity of environing compression loads on a housing of tare and formation of imperfections on covers. The transport packets fastening properties There are used, quite widely at factories a transport packets fastening by their wrapping with elastic polymer film using rotary type machine. Under a comparative simplicity of such machines construction, the wrapping process has an essential disadvantages range. There is given, in the article the analysis of packets fastening disadvantages with elastic polymer film and the recommendations for their removal are formulated. DESIGN  Fibonacci serves to design
Any normal human is arranged so, that is eager to a harmony permanently - with the nature, in relations, and to the visual harmony of course. In all probability, a certain intrinsic etalon that worked up by previous generations and perfected with obtained education makes a human to estimate the around world just from this position. Our brain analyses a milieu, categorizes to rectangular components, gives them an assessment and collects in completely again as a childish meccano as. However, the process occurs at the subconscious level and the most people even don't surmise about it. They feel only: I like it or I dislike it. Nevertheless, professionals, especially designers, must not only know and feel the process and be able to explain and manage it. Furthermore, they must forecast and construct it in order to make own design-project competently. Polygrafika  Measure!
(why a laboratory in typography and how to equip it)
For the qualitative printing drawing a typography employers shall everywhere measure a lot of parameters concerning as to the room microclimate, half-stocks and obtained production quality, and to the printing press state. Here is, in the article, sited examples of different measuring means for parameters volumes determination in the main three fields, their application and these volumes impact to the printing drawing quality. Marketing  The analysis of technical and commercial characteristics lines for polymers processing
The competitive ability conception of technological lines for polymers processing is quite complicated and it is included, besides of quality level and price, a whole parameters range as, for example a delivery terms, payment conditions, transportation to the operation place condition, customs duties volumes balancing and commissioning volumes, warranties and so on. Taking into account all the mentioned above, the analysis of technical and commercial characteristics technological lines may be performed by means of the lines competitive ability integral index for a tubular film production on the screw extruder base with 45,63mm screws diameter. The method, which is given, may be used for a wide range of packaging equipment. Ñontemporary packing - falsification control method The reliable methods system on falsification control creating is the main direction of population health protection for each economically developed country. In this connection, 2004 was declared as the falsification control year. A contemporary packing plays very important role in the problem solution. The protection from falsification, under contemporary market conditions, is carried on all possible directions: trade organizing control, products packing and quality control. Examples of control carrying with a trade organizing and packing quality (labels drawing, corking mean), that will allow to consumers to distinguish an original product from its falsification. Ecology  Whether the processing of the used container from PEÒ is possible?
The updating of scraps PEÒ by crystalline polymers PP and HLDP enables to stabilize the technological process of extrude and moulding under pressure, and also to receive by these methods of an products of small sizes and mass (up to 20 g) satisfactory quality.
On a foundation of obtained outcomes the project of specifications on moulding products with usage of scraps PEÒ and their mixtures with other polymers of engineering and economic assignment is developed. Secondary processing of the used packaging from PET For the complete analysis of physical properties of a material, except for reological and mechanical, it is necessary to know and heat-physical of its property, as last give complete introducing about possible ways of processing of polymeric materials.
