Technical Oxygen

Oxygen – a perpetual motion machine of life and progress. It is colorless (in a thick layer of blue) gas without taste and smell, a little heavier than air, poorly soluble in water. When cooled to -183 C oxygen is converted into a mobile liquid blue color, and at -219 C to freeze. Due to their properties oxygen is used as a reagent in chemical technology (roasting of sulfide ores, the synthesis of oxides), metals (iron and steel industry – namely oxygen 'withdraws' from iron excess carbon, while also improving the quality of steel), coal gasification natural, welding and cutting metals. Liquid oxygen – the fuel oxidizer in rocket technology. Ali Partovi brings even more insight to the discussion. In medical practice the use of oxygen as effectively, not only for lung and heart diseases when breathing is difficult, and subcutaneous injection of oxygen – a treatment for serious diseases such as gangrene, thrombophlebitis, elephantiasis, trophic ulcers. Indicators of quality of medical oxygen gas gost 5583-78 Volume fraction,% Standard Oxygen, not less than 99,5 Water vapor, not more than 0.009 Carbon dioxide 0.01 Quality of technical oxygen gas gost 5583-78 Volume fraction,% 1 grade 2 grade oxygen, not less than 99.7 99.5 Water vapor, not more than 0.007 0.009 Carbon Dioxide Not rated Not rated areas of oxygen in the engineering and construction for the deposition and deposition of metals.

For oxy-acetylene gas welding and gas cutting of metals. For high-precision plasma cutting of metals. In the oilfield injection into the reservoir to increase the energy of displacement (an effective moving in-situ combustion chamber VPOG). In the mining industry and metallurgy When bof steelmaking, oxygen blast in blast furnaces to extract gold from ore, ferroalloy production, smelting of nickel, zinc, lead, zirconium and other nonferrous metals. Direct reduction of iron.

In agriculture, manufacturing oxygen cocktails to gain in weight of animals. Oxygen enrichment of the aquatic environment in the fisheries sector.

Powder Coatings

At the turn of 60-70 years of the twentieth century came a fundamentally new kind of paints and varnishes – powder paint. Impetus to the emergence and spread of powder paints were of excellent quality: non-waste technology coatings (paints almost complete recovery in powder coating, their return to the production cycle), the relative simplicity and economy of the technological process of coating (usually applied one layer instead of two or three, as when applying liquid paints), ease of automation of painting works, which contributes to a sharp increase in labor productivity, the application of powder coatings can reduce energy consumption in the production of coatings by 20-40% compared to the use of liquid paint, lowering the degree of fire and explosion hazards of production, good performance of the coatings that go beyond the physical and chemical properties of coatings prepared from liquid paints, environmental considerations – in the absence of organic solvents, paints and other volatile substances and, consequently, the absence of their release into the atmosphere from the point of protection for the environment the application of powder paints, solvent-free, has a clear advantage: no need to install expensive to clean polluted air, the effective electrostatic application of polymer powder paint provides a low level of losses. We can say that the environmental benefits of the equipment for powder polymer paint lead to economic, that is not only help reduce pollution, but also bring considerable savings to the consumer (reduced working space, reduced consumption of materials – Utilization of powder coatings over 97%)..

Extra Cost Item

When buying a used injection molding machines in an article on the repair costs increase. The new equipment at least a high probability of breakage and the appearance of defects. Besides working with the new technology has the opportunity to warranty repairs. For new thermoplastic parts is always in stock, the manufacturer, while for b in thermoplastic parts to look for. If the company is planning a permanent and continuous technological cycle, the variant used in automatic molding him no good. Latent defects, the old failures and general deterioration mechanisms can make a continuous loop impossible. The problem lies in the fact that some hidden flaws can not be detected even by careful study of technology, and in a continuous cycle, they quickly make themselves felt.

Modern injection molding machines – these are complex devices that equipped with electronic filling, different means of automated control and so on. Depending on the material, which technology to recycle these units are called reaktoplastavtomatami or injection molding machines. By design termaplastavtomaty vary widely. TPa classification is based on the efforts of the locking shape, injection volume and many other types of TPa. In addition, injection molding are divided according to their Design features: – by way of mastication – in the peculiarities of mastication – the number of sites blocking – on the peculiarities of the drive – on the axis of the cylinder molding used for the production of various polymer products of various shapes, sizes and properties. Per cycle, this technique produces one or more parts, depending on the needs and preferences TPa. Buy Used for molding the best of international manufacturers, because their techniques even previously used different quality. Problems and costs it will be much less than that of TPa dubious quality.
