In recent years, the problem of pollution development in marble has been increasingly exposed. Many of the original green mountains have been dug up, and the pollutants such as waste gas, waste liquid and waste residue generated during the mining process have also caused serious damage to the ecological environment. In recent years, the problem of pollution development in marble has been increasingly exposed. Many of the original green mountains have been dug up, and the pollutants such as waste gas, waste liquid and waste residue generated during the mining process have also caused serious damage to the ecological environment. To make matters worse, over-exploitation has caused many natural stones to be on the verge of extinction. How do we save the ever-disappearing marble?
No damage without buying and selling! Without buying marble, we can also buy a marble alternative – marble tiles. This tile has the realistic effect of marble and the superior performance of the tile, noble and elegant, hard and durable, environmentally friendly and pollution-free, suitable for multiple indoor spaces such as living room, bedroom and kitchen.
Nowadays, marble tiles are all red in the terminal home decoration design market, and the red and white building materials "target=_blank> building materials circle is favored by more and more consumers. Then, as a smart and fashionable consumer, how to choose high What are the marble tiles of good value and good quality?
Trick 1: Fidelity
Fidelity is the life of marble tiles, paying attention to maximizing the original stone features on the tiles. Its stone grain reduction degree of 99.9% is the quality of marble tiles.
Simple discriminating method: Comparing tiles with natural marble, it is better to remove impurities without impurities.
Trick 2: Repeatability
In the home space, the rich texture of the tiles will make the space look smooth and natural, bringing a comfortable and visual enjoyment, while the texture will make the space look stiff and stiff, and the stone texture is not repeated. ≧5 square meters is good. The essential qualities of marble tiles.
Simple discriminating method: extract a box of tiles and tiling on the ground to see if the pattern is repeated. The lower the repeatability, the better the decorative effect.
Trick 3: Fine India
Grid problems have always been an important factor influencing the high-definition of marble tile patterns. Processes like the world's leading 5D Symphony inkjet can minimize this, making bricks more vivid and HD. The surface texture of a good marble tile should be a high-precision printing with a precision of 360 DPI.
Simple discriminating method: See if the pattern is clear, the quality of the tile should not appear blurred texture, the problem of mechanical printing traces obvious, the distance from the tile 10CM can not see the grid is the top.
Trick 4: Vitrification
Water absorption rate has always been one of the criteria for measuring the quality of ceramic tiles. Tiles with low water absorption rate are not easy to absorb dirt, and it is more convenient to take care of. Marble tiles that meet the 7-star standard should have a water absorption of less than or equal to 0.05%.
Simple discriminating method: If the water droplets are on the back of the tile, if the water is wet or not, the higher the density of the tile, the better the quality.
Trick 5: Hardness
The higher the Mohs hardness, the more durable the tile. If the hardness of the tile is insufficient, the tile will be easily damaged. The 7-star standard tile should have a brick Mohs hardness greater than 6 levels.
Simple discriminating method: use a hard iron such as a blade to swipe the surface of the tile, and the scratch-free one is the top grade.
Trick 6: Self-cleaning
The self-cleaning degree of the tile is derived from the denseness of the tile glaze. The higher the density, the harder it is to penetrate the tile. The anti-fouling coefficient should be greater than or equal to 5 to meet the requirements of the 7-star standard tile.
Simple discriminating method: Drop ink, soy sauce, vinegar, etc. on the surface of the tile, wait for a while and wipe clean, no residue is the top grade.
Trick 7: Quality of Examination
Different brands, the same size of the tile, the higher the weight, the thicker the tile, the more the material, the higher the density. Products that do not meet the standards and cut corners will affect the durability of the products. The density of marble tiles should be ≧25Kg per square meter of tile weight.

In short VFD, is an energy saving device by converting fixed frequency to adjustable frequency to control AC induction motor in variable speed base on the load's changes.
VFD also know as variable speed drive, frequency inverter and adjustable frequency drives. VFD also works as a phase converter to convert single phase input to three phase output in small ratings.
Frequency (or hertz) is directly related to the motor`s speed (RPMs). In other words, the faster the frequency, the faster the RPMs go. If an application does not require an electric motor to run at full speed, the VFD can be used to ramp down the frequency and voltage to meet the requirements of the electric motor`s load. As the application`s motor speed requirements change, the VFD can simply turn up or down the motor speed to meet the speed requirement.
HUAFEI company is expert VFD manufacturer in China, its VFD is mainly used for the machine in coal mine, such as the hoist, belt conveyor, ventilator, water pump etc. Explosion proof type is used under ground with combustible gas and dust. Medium Voltage VFD is mainly used for hoist ventilator or other motor with medium voltage input.
