Air purification carbon bag useful?
- Can only be activated carbon surface area of toxic and harmful gases to be adsorbed. If the spread of small range, the number of small, placed the time is short, for the whole room, its purification effect is extremely weak, basically negligible. In addition, not all activated carbon can remove formaldehyde and activated carbon in addition to formaldehyde is the primary modification technology is better, also like the allerair purifier is not simply the use of activated carbon technology, the gas canister added a certain proportion of special adsorption agent and stabilizer, in order to have a good purifying effect.s
Coal quality test, Mt, Mad, Aad, Vad each represents what mean
- 1, all water (Mt), is the sum of all the internal moisture and external moisture in coal, also commonly used Mar said. Usually under 8%2, air dry base moisture (Mad), refers to the coal in the air dry state contained in the water can also be considered to be the internal moisture, the old national standard has called "analysis of base water"s
There are several categories of coal sampling machine
- There are three kinds of coal, lignite, bituminous coal and anthracite. The composition and quality of coal are different, and the calorific value is different. The unit mass of fuel combustion when the heat is called calorific value, which can produce 29.27MJ low calorific value of energy can be converted to 1 kg of coal equivalent (standard coal), and the standard conversion of coal consumption.s
Coal is used to do?
- Lean coal can also be used for power generation, power plant boilers and civilian fuel etc.. The typical lean coal produced in Shanxi Province, Xishan Coal and electricity company. Lean: volatile and moderate adhesion, mainly used for coking. In the coking process may produce some of the glial, glial layer thickness of 6 - 10mm. Produced by coal coking coke, high mechanical strength and abrasion resistance is relatively poor. In addition to the part of high ash and high sulfur coal, coal and other coal blending coking often. Coking coal: strong coking process, medium volatile (16% - 28%), is mainly used for domestic coking coal coking coals
What is engineering coal
- Coking. In the coal carbonization furnace, air heating, organic matter in coal with the increase of temperature is gradually decomposed, the volatile substances in gaseous or vapor state to escape, as coke oven gas and coal tar, non volatile solid residues for coke. Coke oven gas is a kind of fuel and an important chemical raw material. Coal tar can be used in the production of chemical fertilizers, pesticides, synthetic fiber, synthetic rubber, paints, dyes, pharmaceuticals, explosives, etc.. Coke is mainly used in blast furnace ironmaking and casting, but also can be used to produce nitrogen fertilizer, calcium carbide. Calcium carbide is plastic, synthetic fiber, synthetic rubber and other synthetic chemical products.s

What is the effect of bamboo charcoal package
- The first is the choice of carbon package appearance, we choose to look at the time not only depends on the brand, but also pay attention to the appearance of the packaging materials used, and now the market any kind of activated carbon texture is hard, but there will still be a small amount of debris generated. In the selection, attention should be paid to the carbon bag outside the non-woven fabric is damaged or ventilation cloth with bamboo charcoal leakage phenomenon. Avoid the use of the process, to avoid a large number of bamboo charcoal overflow, causing pollution.s
