During the 119th Canton Fair, the picture of a Shenzhen trading company became an overnight hit in ceramics export groups on wechat because a banner read “USD 1.99/sq.m UP”, which was the extremely low price in the export sector, was shown on the photo. Mr. CTW has been this fair. But before seeing this banner, Mr. CTW found one other banner that said USD 2.99/sq.m in another stand. Though the stand size only covered a small area of 9 sq.m, there were many visitors checking the products inside. It was more lively there than in some big stands with customized decoration. Low prices, like “USD 2.99/sq.m”and “USD 4.20/sq.m”,are the stunt to draw ... Read More →

As one of the most influential Chinese inventions ,paper has benefited peple all around the world. It was introduced to the west. Gradually people all over the world knew paper was so helpful that many famous works and paintings appeared. No matter in China or the west,in the walks of art ,education and so on, paper plays an important part in peple 's hearts. Specialty paper is for some particular uses with a small production. there are various kinds of specialty papers, and all kinds of papers for special purposes and art papers are collectively referred to as specialty paper. In order to save the confusion of names caused by the variety of g ... Read More →

How to distinguish the LED lamp and LED tube light? Many people believe that the LED lamp and LED tube light is used for household lighting should belong to the same kind of product, actually otherwise. We can often from both the position and application effect.     A, from product performance to distinguish above:   LED tube light is a light shot inside the embedded in the ceiling lighting lamps and lanterns. Belong to the directional lighting lamps and lanterns, can only by the light of the opposite, its advantage lies in the more concentrated than general lighting lamps and lanterns of lamps and lanterns, usually used for general lighti ...

PSA Nitrogen Generator making device is according to the pressure swing adsorption (PSA) technology, using high quality carbon molecular sieve as adsorbent separation oxygen nitrogen directly from the compressed air. After dry compressed air purification, under the effect of pressure, the use of oxygen diffusion in PSA Nitrogen Generator carbon molecular sieve pores adsorption rate greater than the diffusion of nitrogen in carbon molecular sieve pores adsorption rate, this feature in adsorption equilibrium has not been achieved, the enrichment of nitrogen in the gas phase was up and form a finished product nitrogen. Then via vacuum to atmosphe ... Read More →

A horn antenna serves the same function for electromagnetic waves that an acoustical horn does for sound waves in a musical instrument such as a trumpet. It provides a gradual transition structure to match the impedance of a tube to the impedance of free space, enabling the waves from the tube to radiate efficiently into space.   If a simple open-ended waveguide is used as an antenna, without the horn antenna, the sudden end of the conductive walls causes an abrupt impedance change at the aperture, from the wave impedance in the waveguide to the impedance of free space, (about 377 ohms). When radio waves travelling through the waveguide hit ... Read More →

COB LED ceiling light is in the LED chip directly attached on the high reflecting rate on a metal mirror substrate high efficiency integrated surface light source technology. This technology has eliminated the conceptual scaffolds, electroless plating, no reflow soldering, SMT process, therefore the working procedure is reduced nearly a third of, also saves the cost of one third. COB LED ceiling light can be simply understood as high power integrated light source, which can be designed according to the product configuration design of the light source of the light area and size. The product features of COB LED ceiling light: Electrical stabi ... Read More →
