Q: What kind of pesticide chili pepper: Anthracnose is one of the most frequently occurring diseases on hot (sweet) pepper. Can cause pepper leaves, rotten fruit, seedling death. General harm is not serious, but in rainy years, the incidence of severe. According to its symptoms can be divided into 3 kinds of black anthracnose, black spot anthrax and red anthrax

Q: General charcoal and activated carbon what is the difference?: But to microporous activated carbon dominant pore diameter is divided into three categories: macroporous (more than 50nm), accounting for about 10 to 30% of the total pore volume, micropore (less than 2nm) accounted for about 60 to 90% of the total pore volume, pore and transition pore (2nm = phi = 50nm), ca. the total pore volume of 5 ~ 7%, the average pore diameter is about 1.5nm. molecular diameter of the harmful gas (formaldehyde, benzene, ammonia, 0.44nm 0.48nm 0.414nm, 0.58nm 0.60nm, toluene and xylene 0.324nm methane etc.) thus, bamboo charcoal for these harmful gases has no adsorption purification function, and it is the diameter of the activated carbon molecular fusion with these harmful gases, the adsorption of harmful gases and the confinement properties are better! 3, the specific surface area of different surface area refers to the unit mass occupied surface area size

Q: What is lean coal, lean coal classification: (2) lean coal (PM). Coal is a high degree of coalification coal, non caking or slight adhesion. No coking coking furnace. In the laminar flame, burning resistance.(3) lean coal (PS). Lean coal is a kind of high rank and low volatile bituminous coal and weakly caking. Typical coal coking, coking, coke powder are generated.(4) (SM). Coal coal is low volatile medium caking coking coal. Can produce a certain amount of colloid in coking. Separate coking, can get large blocks, crack less, shatter resistant better coke, but poor wear resistance of coke.

Q: On behalf of the company to study the coal test, which can help me to explain the online test of coal each indicator of the process, thank you: (1) free water and combined water in coalThere are two types of water in coal according to their different forms. Free water is based on the physical adsorption state in coal particles and coal particles attached to the capillary inner surface of the water; combined water is also called crystal water is combined with mineral water in the coal chemical way. Crystalline water, such as calcium sulfate (NaSO4.2H2O) and aged soil (AL2O3.2SiO2.2H2O). Free water in 105 ~ 110C temperature after 1 to 2 hours can be evaporated, and the crystallization of water is usually more than 200C in order to decompose precipitation.In the industrial analysis of coal, only the free water is measured.

Q: Bamboo charcoal package is valid: The 2 part of the harmful gases such as formaldehyde, ammonia and other dissolved in water, so the water contains some of the harmful water soluble bamboo. After drying, this part of the harmful substances will evaporate into the atmosphere with water. Of course, to the outdoor drying.3 bamboo charcoal will absorb a lot of microorganisms, they will be attached to the surface of bamboo charcoal or blocked in the hole crossing, affecting the absorption of bamboo charcoal on other harmful substances. After drying in the sun, the role of ultraviolet light, some of the microbes will be killed, roadblocks were cleared.

Q: The development history of activated carbon: 157 years, Claudius medical papers mentioned in the vegetable and animal sources prepared charcoal, for the treatment of various diseases.Chinese Li Shizhen of the Ming Dynasty (A.D. 1518-1593) edited by Compendium of Materia Medica mentioned in charcoal for treatment of diseases.In 1773, Scheler through a large number of experiments found charcoal adsorption capacity and adsorption of various gases.In 1777, the effect of charcoal heating and gas adsorption was reported, which led to the "condensation adsorption theory".In 1785, Scheler studied charcoal adsorption gas, the adsorption capacity of steam from the steam to a series of organic chemicals and a variety of aqueous solutions using charcoal decolorization, especially the production of tartaric acid commercial applications. This seems to be the first systematic consideration of the adsorption of charcoal on the liquid phase.

Q: I would like to ask you, the total energy consumption (tons of coal) mean?: Does not refer to the actual coal, the actual coal, oil, natural gas calorific value are converted to standard coal

Q: What is long carbon powder: 1, carnivorous barbecue, because "charcoal" stable combustion, high calorific value, ignition temperature is 600 DEG C, the combustion temperature of >800 DEG C, smokeless combustion, flameless, barbecue the food color aroma and taste is good, is the most elegant barbecue fuel.2, cooking will be prepared long carbon into the meal in addition to odor and other harmful substances.3, the production of cosmetics in the process of adding the right amount of ultra-fine "long carbon" Wei powder can absorb harmful chemicals, reduce the damage of cosmetics on the skin4, can be prepared after the long carbon particles into non-woven packaging and then made into pillows and mattresses, on the human body from the health care role.

Q: Tell me the trouble which the coal index English code in this format please tell me - - water - ash volatile sulfur - fixed carbon - coke slag characteristics of heat - Requirements: the last edition of the new national standard GB and best can mark up compared with the old standard, the new national standard is different, in the measurement and as a way of testing, please inform. .: Now we often report the moisture index:1, all water (Mt), is the sum of all the internal moisture and external moisture in coal, also commonly used Mar. Usually below 8%.2, air dry base moisture (Mad), refers to the coal in the air dry state containing water. Can also be considered to be internal moisture, the old national standard has called the "analysis of water base".

Q: What is the name of the coal Juban and Hang Hau price?: At present, the price of the pit is the seller and the buyer in the mouth of the transaction price, the price is bare price, including the basic of sustainable development of coal
