FAQ

Activated carbon shelf life
Activated carbon has a shelf life, activated carbon after adsorption saturation.
The standard Meizhi is what mean?
The standard Meizhi is calorific value per kilogram of 29 million 300 thousand coke coal
What is the use of activated carbon
Activated carbon is a kind of purification material, adsorbent, catalyst
How to identify true and false activated carbon
Traditional quality identification methodFirst, the activated carbon placed in the water to see if it will produce bubblesThe activated carbon placed in the water, if it produces a series of small bubbles, and there is a bubble sound, it shows that the activated carbon adsorption capacity, quality is particularly good
Activated carbon in water purification equipment harmful to human body?
Activated carbon does not dissolve in water, even if some small particles floating in the water, drinking will not harm the body. Please don't worry.
Coal chemical production technology is to learn what ah
Coal chemical production technology mainly for the production of coal chemical industry and other coal deep-processing enterprises, cultivating high skilled talents engaged in technology management, coal chemical production system operation and maintenance, inspection and analysis of the quality of coal products, coal chemical project construction management and design work.
The difference between graphite particles and activated carbon particles
Belong to the six party system, with a complete layer of cleavage, cleavage surface with molecular bonds, the molecular attraction is weak, so its natural floatability is very goodActivated carbon and activated carbon black. Black amorphous carbon powder or granular activated carbon. The main components other than carbon and oxygen, hydrogen and other elements. The activated carbon in the structure due to crystallite carbon is irregular, the cross connection between pore,
Types of coal and how
It should be noted that the G value is greater than 100 of the coal, especially coal mine average G or several samples were above 100, generally can not measure Y value determined for coal or gas coal class.Also stipulated in China's coal classification standard, the G value is greater than 85 of the coal, if not measured Y, also available Oaxaca expansion degree B value (%) to determine the boundaries of coal and gas and other types of coal, namely Vdaf<28% coal, tentative b value of >150% for coal to Vdaf>28%; coal, provisional b value of >220% for coal (when the value of Vdaf <37% (Vdaf) or gas when the value of >37%). When there is a contradiction between the classification of coal according to the b value and the type of coal classified according to the Y value, the coal class determined by the Y value shall prevail. Thus in determining the new classification of strong caking coal brand, can only measure the Y value and temporarily B value.
