Powder Coating

Powder coating of metal is already used in industry as one of the most reliable and cost-effective methods of applying protective coatings. And we are not surprised to hear that parts of the car or constructions have completed the powder coating. Quality and durability coatings are widely used in areas where colored objects uses a lot of people. For example, a staircase in shopping mall – how many people each day goes on it? Tens and hundreds. It is clear that the usual coating wears off quickly, but the powder coating can stand (unless it is made to the technology). However, the scope application of powder coating is not limited to industrial production and mass use of objects. In fact, powder coating has been successfully used in smaller scale.

The most simple Example – steel doors, which now stand at almost every apartment. If the manufacturer claims that the metal surface applied anti-vandal cover, you know – here we used powder coating. Only this technology makes it possible to form a solid layer of paint so that it can successfully withstand any mechanical stress. And note that the decorative features of the powder coating does do not suffer. Modern techniques make it possible to achieve different visual effects, including such complex, like a chameleon or tissue. The process of powder coating metal can take place in different ways: for today developed many ways of coating literally on all occasions. Of course, in specialized shops is used for this high-tech equipment, which not only provides high quality, but also an unprecedented low percentage of waste. However, there are manual settings, sprayers, allowing strike coverage on small items without opening the entire pipeline. With all of this powder coating is available for the average consumer – most shops take orders for staining single products and small parties.

Processing Equipment

Breakthroughs stimulate the production of new models of equipment for the production of paper. In our time, waste management and closed loop are important. These two factors often are decisive in the selection of equipment, as they allow full use of all raw materials and saves significant finance company. Sizes and compatibility of equipment for the paper also affects the organization production process. After all, the compact machines and mini-mills, which offer high performance, excellent pay off and allow you to save your workspace.

Good hardware compatibility promotes the expansion of capacities by linking various machines. This allows you to organize the entire production cycle of paper products. Modern equipment for the paper is a reliable and high performance. But do not forget about one more positive thing. It is easy to operate. This factor is often the deciding factor in choosing the equipment, since the ease of machine control and efficiency training eliminates any production from the mass of personnel problems.

Wide choice of capacities can help solve many problems. For example, produced a mini-factories for recycling of waste paper are able to give the final product in the form of bobbins with paper sanitary purposes. Waste paper, after a series of operations is prepared paper pulp, which goes to the grid table, where distributed and calibrated. Later, pressed paper is dried, cleaned and wrapped in a spool or log of a certain size. Good compatibility of equipment can immediately rewind the reel to reels toilet paper and paper towels. During rewinding paper unwound tighter and softened by stamping. In the next stage on a special machine is cutting into convenient rolls. After that, a special machine performs the packing boxes. Along with the mini-mills, there are stand-alone machines that perform a single operation, such as packaging, rewind or cutting. Many of them are perfectly integrated into the complex equipment paper. Bobinorazmotochny machine is used to rewind the reels in the log of which is further made rolls of toilet paper and paper towels. Machine for cutting paper base with a knife and tape convenient system setup used for rolls of paper. Size and sharpening the knife can easily adjust the relevant mechanisms of the machine. Among the variety of equipment for paper machines should be allocated production of recycled paper napkins. They are characterized by high profitability and good performance. This is achieved through the use of proven components for tools designed for high loads. Also cheapness of basic raw materials – waste paper, waste and closed loop production saves significant assets of the company. In the process, by stamping, folding and cutting, achieved the desired parameters of the future products. The work machine for the production of napkins, as most equipment for the paper, is semi-automated and requires minimal operator action. The output is ready with paper napkins embossing. Convenient and simple.

Processing Metal

Processing of metal man made more than five thousand years. At the dawn of blacksmithing use soft metals, which are easy to handle. In the jewelry business has long used gold and silver, and for creation tools, and quality of weapons used copper, and much later they began to process the iron as a more time-consuming stuff. Most metal working was poor quality and very low volume production. But with every passing decade, the need for high quality metal is growing rapidly and by the early twentieth century, the volume of smelting reached twenty-eight million tons.

With the development of industrial production, except for the smelting of ferrous metals, increases the need for extraction of rare metals such as copper, aluminum, titanium, zinc, tungsten and others. To obtain the metal with the necessary physical and chemical composition are two basic method. The first method involves obtaining the metal with the desired characteristics of the starting materials. The second method allows to obtain the necessary form in a plastic state without altering the chemical properties material. Allocate the following technological processes of metal: pressing, forging, drawing, stamping and rolling. When such methods of plastic processing of metal attached to not only the desired shape and size, but also significantly improve the mechanical characteristics of parts. The most important method of processing metal is definitely rolling, and accounts for 80% of the melted metal and each year the release of finished steel increased, extended range and improved product quality.

Rolling metal produce large products for industrial use in the construction and engineering, as well as receive various blanks (sheet steel, bars) for further processing by other species – stamping or forging. Pressed for forging is often used rolled billet. Drawing using metal produced on wire looms. One of the most important facts production of finished steel is the principle of continuity of the process and automation of manufacturing operations. To improve the characteristics of products rolled using heat treatment, tin, alloying and coating protective layer. In today's world of metal all the more important are the processes of pressing – cold heading, forging, extrusion, which allow to make the most complex piece forms, even from metals that are poorly exposed to the strain. A distinctive feature of the metal pressure is relatively low energy consumption and low metal loss. To increase production, reduce the cost and improve product quality of metal implement special stamps, improve mechanisms for automatic transport and forging operation that applies technology induction and contact electric heating billets are shops for the manufacture of universal and specialized components that allows you to create automated and in-line conveyor belt. The scientific approach to plastic metal processing allows to calculate the cost-effectiveness, to determine the most rational conditions for obtaining high-quality products, as well as select the optimal modes of technological processes, as well as necessary equipment.

Natural Rubber – A Product Of The Future

The technology of production and processing of natural rubber invented before plastics were developed. Previously, natural rubber is obtained only in the countries of South America. Natural rubber production started in industrial scale by the mid 19 th century. Processing of natural rubber in the material used for technical purposes, was made possible in 1839 when an American scientist Goodyear laid the foundations for the process of vulcanization. Earlier, in 1827 British scientist Hitchcock found that natural rubber with proper machining loses a high viscosity and low processability. Softening process in the processing of rubber on rollers it is called mastication.

In the early 19 th century was opened Ebonite. The rapid development of technology led to extensive use of rubber in such fields as electrical engineering, as a great insulation. Developing automotive industry experienced a need for a rubber pneumatic tires. Constantly growing demand for automobile tires were subsequently transferred to the tires for airplanes. A special method of manufacture rubber compounds is to use a large percentage of natural rubber, kremnezita that delivers remarkable quality and level of consumer properties of the products. Formed in the late 20 century, the possibility of rubber production by synthesis, restricted the use of natural rubber. Synthetic rubber is a product of polymerization.

Used in the manufacture of tires as a substitute natural rubber or a mixture of them. In the following years the development of industrial and technological processes, thus making the synthesis of rubber on an industrial scale. Now expand resource base and further improvement of the most important feedstock for rubber production is one of the most important tasks. For many of the characteristics of synthetic rubber is not inferior to natural and even partially superior to him. It is produced in much larger quantities than natural.
