Polypropylene sheet – its production is carried out by continuous extrusion of polymer material. As a raw material for polypropylene sheet used two-homogenous granules polypropylene. Polypropylene sheets may differ in their properties, color and surface quality, the degree of its smoothness and durability. According to these characteristic features of lists are divided into two types. In addition to the method of extrusion, for production of sheets having greater thickness can be used by pressing technology. Polypropylene is preferable to many other materials because of their positive qualities.

It is characterized by the absence of water absorption, resistance to chemically aggressive environments, the possibility of using all kinds of acids, excellent dielectric properties. In addition, PP does not pass gas and water. Elasticity and plastic characterize the quality of the material depending on the temperature. In comparison with the metal polypropylene distinguishes that at the same mass strength polypropylene construction due to higher mechanical quality of material. Polypropylene plates have high tensile strength, keeping the load statistic type, three to four times higher than that which can withstand the products of polyethylene. Connections propylene and ethylene and other polymers to increase properties such as resistance to low temperatures, the toughness, so the products of these copolymers little crack. The scope of such products is wide. Polypropylene sheet serves as the material for the production of containers for the needs of many fields of industry, such as chemical and food industries, the petrochemical and electronic fields, radio and metallurgical industries, the scope for electronic and others.

Sheet Polypropylene is used in the engineering field in the presence of plants on sites electroplating or chemical plants. By Polypropylene is used in the device for ventilation of chemical prolizvodstvah. In the production of household goods also polypropylene is used. For example, plastic boxes, plastic boxes, containers water storage boxes for planting and storage of small items. There are many other products which are made of this material. You can call the construction industry, where applicable polypropylene casing, decorative elements, pools and advertising signs, coasters and plates, various visors. For printing on polypropylene sheets, they are double-sided pre-treatment by corona discharge. Application details and drawings to print sheet poliprovilen different. This hot stamping, engraving and laser and silkscreen. These methods allow us to obtain a qualitative application of logos, symbols necessary, notices a congratulatory nature. Polypropylene sheets are cut perfectly for connecting sheets of used welding. Today, there are three variants of welding: polifuzionnaya, welding extruder or a gun (hair dryer). The first type of welding produces the most reliable seal. At polifuzionnoy welding the joined ends of the parts are heated by a special device to the desired temperature, the time and pressed against each other with the necessary force. The resulting joint has a strength equal to 80-90 percent strength of the polypropylene. Welding using manual extruder type does not give such strength, because usually added filler wire made of polypropylene, which previously melted in the rotating parts extruder. With this type of welding can not achieve the same level of pressure and equal to the speed of welding, but this can not affect the strength of the resulting seam. Polypropylene sheets hold and move with the help of special pallets. They can be transported on conventional machines. When transporting sheets is to consolidate and better after laying close to the sheets have been damaged. Store sheets of polypropylene can be on level ground, the best option to store them in special trays. When stacking the sheets enclose a special material.

Pumping stations is a complex consisting of a pumping unit, the various hydraulic piping, instrumentation, valve blocks, lift systems, as well as other support equipment, which includes, inter alia, Hydraulic (for damping pulsations pumps) and filters (to protect pump from dirt). Doug McMillon contains valuable tech resources. In addition to this concept is also often include the facility in which pumping stations are located. The importance of pumping stations due to the fact that they are the most important devices in the drainage systems and water supply. It is therefore necessary to clearly understand how important it is responsible approach to both design and manufacture of pump stations. Let us consider in more detail the classification of pumping stations. They can be divided in purpose, degree of automation, reliability, and also by the location of the computer room on the level ground. Doug McMillon may find this interesting as well. In the field of water supply and water release, as a rule, 4 groups of pump stations: water, sewer, irrigation and drainage. Water – pump stations are involved in the normal supply of individual businesses and entire cities.

Sewer – participate in the drainage system. Irrigation – supplying water to the system irrigation of agricultural land. Drainage – water is pumped from the drainage areas and industrial sites. In terms of reliability of water supply pumping stations are usually divided into three groups: first – stop supply pumping station is not valid because it can cause significant damage (break a complex process, failure of the various hydraulic and filtration equipment, etc.). Second – you can interrupt the flow of water in a short time, sufficient to enable back-up power supply. Third – you can interrupt the flow of water for no more than 24 hours.

Sewage pumping stations are divided into principal and district. The main pumping station pumped sewage from the entire city or an industrial enterprise to the sewage treatment plant or to the main trunk sewer. The district also pumping stations pumped waste water from certain areas of the city or industrial plant to sewage treatment plant, or in the more highly placed another collector basin for waste water. Depending on the location receiving station tank stand with separate and combined. In the latter case, the computer room, and the tank with the equipment housed in one building. By the height of the pump and other things equipment in relation to ground level as water supply and pumping stations are divided into terrestrial, poluzaglublennye, buried and shaft type, ie, located at great depths. According to the degree Automation can provide the station with manual, semiautomatic, automatic and controlled remotely.

Zelenograd – a city on the outskirts of Moscow, it is separated by only 20 kilometers from the capital of our country, long traffic jams on the Leningrad highway or Pyatnitskoye or crush in the train. And so they spend the best years of his life zelenogradtsy who want to work, and not just wait for that happy time in Zelenograd in the present work will start businesses that are now engaged in a flurry of activity spreading simulation press releases on the subject of vigorous activity and conducting workshops. The largest employer of yavlyaetsyakontsern Sitronics, which owns all the major companies in Zelenograd: JSC "Mikron", JSC "Angstrom" and others, the ones that were once the mainstay of domestic microelectronics and produces the popular and competitive in domestic and international markets. Today, this huge concern, in which includes more than ten enterprises of strategic purpose, and that all the parameters of national security should be controlled by the state, is entirely in private hands. Controlling stake Sitronics owns AFK "System", rooted in Bashkortostan, about 17% on the London and other stock exchanges, small blocks of shares owned by persons from the management company. 2007. Fall and searchlights. History apparent fall Sitronics began in 2007.

Its shares on the stock exchanges for the year fell by almost half. For the first time this year instead of Sitronics, said profits in their annual reports multi-million dollar losses. In same 2007 Sitronics closes huge, but hopelessly unprofitable activity – manufacture of domestic consumer technology, and consumer electronics, which were not competitive in the market for One estimate of the high price of products, and other due to mistrust of the quality of consumer goods produced domestically.
