Moisture is an invalid component of activated carbon, the lower the better.
Drying method is generally used, that is, the carbon sample into a pre-dried and constant weight with a lid weighing bottle, accurately weighed 3 to 5 grams of activated carbon samples, and then placed in an electric oven, at (150 ± 5) ℃ temperature drying at constant temperature above 2h to constant weight, and then placed in a desiccator, cooled to room temperature and weighed. The moisture content is expressed as a percentage of the mass of the lost sample.
Ash refers to the residue of inorganic salts or oxides remaining after burning at a high temperature, the lower the better.
After a certain mass of activated carbon sample which has been dried in an oven at (150 ± 5) ° C for 2h is burned at (800 ± 25) ° C for 1h, the percentage of the residue obtained from the sample is the ash content of the activated carbon .
3, wear strength strength is the ability of anti-damage activated carbon, the higher the better. GB using the ball mill method, take 50ml dried, a good selection of samples, placed in a drum with five balls, according to a certain speed operation 5min, remove the sample sieved 5min, with the retained in the strength test sieve The percentage by mass of active carbon sample taken by the particles is taken as the strength of the activated carbon.
4, particle size (distribution) Activated carbon particle size of activated carbon bed pressure drop and adsorption speed.
Measurement, according to the technical requirements of the product, select a corresponding set of standard sieve, according to the size of the sieve from the top down and placed on the sieve shaker, weighed 100g of activated carbon sample sieve sieve placed in the upper sieve, Start the vibration sieve machine vibration for 10 minutes, and then in turn remove the layers of sieve, collect and weigh the samples on each sieve layer, calculate the sample retained in the sieve layer on the quality of the sample mass percentage, get activated carbon particle size distributed.
5, packing density
Also known as pile weight, affect the size of the device design and floating rate.
The dried activated carbon sample by the vibration feeder at a speed of 0.75 ~ 1.0ml / s free fall into the measuring cylinder, take the volume of filling and weighing the quality of the known activated carbon, the ratio of the packing density.
6, the fire point
Since the adsorption of activated carbon for gas phase adsorption is exothermic, the carbon layer may ignite if sufficient thermal conductivity of the carbon layer is not considered. Therefore, the detection of activated carbon ignition point is necessary. In the air flow at a constant heating rate of heating the sample, with the temperature rise, the carbon-like temperature will suddenly exceed the temperature of the air into the charcoal layer, the temperature at this point is the ignition point of activated carbon.
7, floating rate
Flotation rate is a measure of activated carbon in water or floating in the liquid phase of a performance, the lower the better.
The dried and cooled 20g sample placed in 500ml beaker, add 200ml of distilled water at room temperature and stirred 2 times, allowed to stand for 10min, the sample floating on the water removed after drying and weighed to calculate the floating rate.
8, pH value
pH is an indicator of acid-base activity of activated carbon and needs to be tested for different uses.
First determine the moisture of activated carbon, calculate the equivalent of 10g dry carbon weight of wet carbon quality and weighed into the conical flask. Take boiled distilled water 100mL, add the flask and charcoal shake. On the heating plate on the heating boil the water, keep boiling 15min, remove the flask, the flask was filtered and the filtrate was cooled to 50 ℃, make up to 100mL, with a calibrated pH meter test.Looking for ideal Activated Carbon Odor Manufacturer & supplier ?
