Look into Market Tendency of Shot Blasting Treatment

May 11th, 2012 at 07:14 am

Shot blasting, as a method of steel surface treatment method, has been developed for nearly a century. Since the first shot blasting machine appeared in America a hundred years ago, shot blasting has been undergoing great improvement and innovation. The very first movable shot blasting machine appeared in the late 1970s, but it had to be pulled by hands. Then, blasting machines driven by motor, hydraulic device and diesel engine came to the fore one after another.

Wheel blast machine is just a perfect example of such innovation. This advance in the machine construction greatly boosts the efficiency of operations. At the same time, the material and size of the shot also gradually varied to cater to the surface treatment of steel items of different width. This also greatly widens the scope of the applications of shot blasting machine. Now, its applications have been expanded into a wide array of industries including auto industry, mechanical equipment manufacturing, and foodstuff processing etc.

Besides these innovations, shot blasting machine also enjoys certain positive factors compared to other steel surface treatment methods. Sandblasting machines is device which blasts metal shots onto the steel surface at a speed as high as 70 meters per second. The powerful blasting force will then remove the impurities attached on the surface of steel item to be treated. Under the influence of negative pressure imposed by dust extraction equipment, the metal shots, together with the impurities will be drawn back into the split system for recycled use. So shot blasting is a comparatively low-cost means for steel surface treatment.

Besides, shot blasting machine produces no substances bad for the environment. The used metal shots are drawn back into the machine for recycled use. The impurities removed are also collected by the machine for further disposal. In contrast, highly corrosive materials like nitric acid had once been used to remove the impurities over the steel surface. But this treatment method was gradually abandoned as a consequence of its potential threat to human health as well as the environment. So as the world, especially developed nations, gradually drafts stricter laws and regulations on protection of environment, more funding will head over to the research and advancement of more advanced shot blasting machines.

In all, the market potential of shot blasting treatment is self-evident as its application has expanded from heavy industry into wider sectors. And it could be predicted that more sophisticated shot blasting equipment will appear in future as the treatment method continues to develop.

May 11th, 2012 at 07:07 am

Glass strengthened plastic pipe is also named as reinforced plastic mortar pipe (RPM pipe). It mostly takes glass fiber and its items as reinforced supplies, unsaturated polyester and epoxy resin of substantial polymer materials as base components, and inorganic nonmetallic components like quartz sand and calcium carbonate as principal raw components.

Reinforced plastic, which normally takes glass fiber and its item as bolstered resources, is termed glass fiber strengthened components or FRP Cable Trays (fiber bolstered plastics). For the different kinds of resins utilized, you'll find polyester FRP, epoxy FRP and phenolic FRP.

Glass is brittle, but is of fantastic transparency and attributes of high temperature resistance and corrosion resistance. Steel is tough and not very easy to break, and it's also proof against high temperature. As a result, folks start to think what a beneficial substance it will be if it could have the hardness, substantial temperature resistance and corrosion resistance of glass and hardness and toughness of steel with the exact same time. After a large number of researches and experiences, this sort of a compound materials is eventually produced. That is glass reinforced plastic pipe, which is as tough as steel.

There are primarily 3 kinds of generation technologies of glass strengthened plastic pipe that are reciprocating filament winding technological innovation, continuous filament winding technology and centrifugal casting technological innovation.

Reciprocating filament winding engineering: Within this technology, the impregnating saturator tends to make a reciprocating motion with the revolving core type. Lengthy glass fibers will probably be extra for the core shaft in specific bevel angle. The explement (wrap angle) is controlled with the ratio among the movement velocity with the impregnating saturator and the revolving speed from the core design. The reciprocating motion of the impregnating saturator is electromechanically managed with the personal computer. The number of filament winding layers steadily will increase right up until it comes to the intended wall thickness. Right after filament winding is finished, the resin in the merchandise has to be solidified. After the solidification, the core design can be separated through the bellow forming machine.

Continuous filament winding technological innovation: On this engineering, the rebar splicing coupler preimpregnates the roving from the resources feeder with the mixture of chopped glass fiber and resin grit. The pipes are getting made in the course of the steady motion of core product.

Centrifugal casting technologies: In this particular technologies, chopped bolstered supplies of glass fiber and grit are fed in to the steel design fastened to the shaft and unsaturated resin with catalyst is injected at one end with the steel type to impregnate the strengthened components. With the centrifugal influence, the resin replaces the fiber and air during the feed and non-porous compacted compound resources are made. For that centrifugal impact, there'll be an interior layer, which can be smooth, brilliant and prosperous of resin, formed around the interior wall of the pipe. The pipe will be solidified in large temperature. Pipes which might be manufactured by this engineering can also be known as FRPM.

At existing times, amount of producers who implement reciprocating filament winding technologies is much more substantial than variety of companies who use another two systems. One of many primary underlying factors is the fact that glass strengthened plastic pipes manufactured by reciprocating filament winding technology have a much more common use and much better suitability.

Vertical tank has the benefit of small area occupation. But people may feel afraid of the thick and high tank, sometimes may also use the horizontal tank.

Stainless Steel Storage Tank & Common Carbon Steel Tank When choosing the air stress tank, materials also play a purpose as important function as volume and condition. Different industries and environments require various materials. Food, pharmacy, cosmetics, these industries must decide on the stainless steel storage tank. The inner skin with the common carbon steel storage tank is only coated with a layer of anti-corrosion coating, which layer will probably be corroded out by the water and oil in the compressed air in the long time use. This will affect the quality from the food and medicine. Therefore we had better pick stainless steel storage tank in these industries.

Stainless steel tank is specially appropriate for the regions of such extreme climates as high temperature and extreme low temperature. If the annual average temperature of your region is 45 degrees below zero or even lower, you must never use the common carbon steel storage tank. Because common carbon steel storage tank will frost crack in such low temperature. This really is very dangerous. Only stainless steel storage tanks are safe in this condition.

In order to lower the cost, some people insist on using common carbon steel storage tank regardless with the temperature limitations. But this will leave potential safety problems. Pressure vessel fabrication concerns enterprise security, we must carefully select.
