immune to this, the more users:)) The purpose of each article – is to present a kind of knowledge. The article should be useful to a person and she will live. In this brief essay I will talk about how the decoration of metal, their advantages and disadvantages and the estimated average prices. So nachnem.Shelkografiya Silk was invented in 1908 in London and patented a technology called Silk screen printing. Principle: The dye is applied through the silk on any surface. It can be metal, plastic, fabric. Badges made using this technology have a high value (about 1.8 cm square of P), low quality graphics and poor abrasion resistance. That photo made nameplate using this technology: Thermal transfer Thermal transfer – is sublimation.
Initially, the film is printed mirror image, then the film is placed upon the surface of the metal and the hot press and hold pressed for half a minute. Quality Graphics satisfactory stoikost to abrasion is poor, resistance to UV light at all. Cost about 2 rubles per sq. cm. At the bottom photo, look at what happened to the plate for 4 months of sunny summer: Chemical etching Steel Chemical etching are also called 'chemical engraving.
" Principle: in some parts of the plate is applied to acid-metallicheksoy layer, then the metal surface is treated with an acid or a strong alkali. The graphics. Cost about 3 USD. per sq. cm. Average quality graphics, amazing resistance to abrasion. Schild, stainless steel can last 50 million years or more. Here are photos: Alyumofoto Alyumofoto – new technology which is the principle that the surface of a plate of metal (aluminum), contains silver particles. At the plate through the negative image was projected and some parts of plaques 'zatsvechivayutsya' ultraviolet light. Amazing quality graphics – you can even move the metal photo. Abrasion resistance is excellent. The cost of 1.5-3 rubles. per sq. cm. The photo below Metallografika Metallografika – a new technology developed by for the needs of the Russian military-industrial complex. The essence of the method: the metal is pre-processed and disclosed his pores. Then the plate is placed in a bath of an organic dye, and then under vakkuumnym clamp to the plate and pressed against the film illuminates the ultraviolet light. Then, the unexposed areas washed with water and applied to the protective oxide layer. Graphics quality, excellent. The stability is amazing. Cost – 0.5 -1.7 rubles per sq. cm.
In encyclopedias and dictionaries published in the mid-nineteenth century, the concept of "napkin" refers solely to the dining room linen. Not much time, and the development of technology, small pieces of cloth or soft paper, which we call wipes, were used not only to ensure hygiene of food and interior decoration. In our time, we can speak about the separation of tissues into: Decorative – small tablecloth, still intended to decorate our homes. Canteen – popular in the business related to public health, and the house, cloth or paper. Hygiene – used for various purposes: to clean and freshen your face, wipe your hands if you can not wash them properly, to prepare a face to the imposition of cosmetic masks, etc. Health – one of the necessary materials, without which it is now difficult to imagine a visit to the dentist or patient care with urinary and fecal incontinence. That production, which is intended to be used for medical purposes, shall comply with the requirements of a lot more than wipes designed for beauty and convenience in daily life. When we go to a dentist or a gynecologist, it is very important that all consumables used in the examination and treatment, not only provided us with comfort, but not proved to be a source of new problems. If compliance with hygiene plays an important role in the use of food, that when we go to the doctor, all tools and materials should be even safer for our health.
One of the major errors grow? Sian enterprises manufacture? Lei PP – an attempt to reach the same production of the full range – both in class density, and volume production. Unfortunately, most often due to lack of proper funding, a deep study of marketing and market conditions, as a consequence,? eat concept of the planned reconstruction. Purchase single road? Yaschih position equipment does not give the desired effect either on volume nor the quality of the products, if in the same processing chain work and obsolescent machinery and technology. Any business, expected to continue and develop the production of PP, in must first define its market position in both series, and the level complexity of the product. If you are unable to complete the reconstruction of production in a short time, it is necessary to develop a single strategy for the long term and planned to implement that plan.
Is encouraging that in recent years there have been serious changes in the manufacturing industry production capacities of the PP. Now completely reconstructed or created several companies, some are planned reconstruction, or will start soon a new building or renovation of production. In conclusion, we offer consider our views on the prospects of time? development of Russian-made PCB. Our view is based on the fact that Southeast Asian countries are close to the peak of its export production capacity. The overriding objective PP industry of China is constantly evolving needs of UBC-rochnogo domestic production, which in future will be directed? Leno to satisfy the domestic market.
Also do not forget that even by Russian standards, 80% of China's population lives in poverty, and this – more than 1 billion people. Of course, China and Southeast Asia will remain the main producers of PP in large batches. However, the export share of medium and small-scale orders will tend to gradually decrease. On this basis, we can assume that the Russian PP industry, there are certain prospects. We believe that over the next five years, Russia has not changed only the volume but also the structure? round production of PP. Already there are production ready to fulfill orders for sredneseriynye boards at competitive prices from Southeast Asia and terms. As new or renovating existing domestic enterprises share of orders placed in the Southeast Asian countries, will gradually decrease and, correspondingly, the proportion of orders placed on the Russian domestic market will increase from year to year.
