    Product Detail
  <span id="result_box" class=""><span>Physical properties of activated carbon testing project introduces 8
items: moisture, ash, particle size, strength, packing density, ignition
point, floating rate, pH value.<br />
</span><span>1, moisture<br />
</span><span>Moisture is an invalid component of activated carbon, the lower the better.<br />
</span></span>
<p>
<span id="result_box" class=""><span>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 </span><span>(150
± 5) ℃ temperature drying at constant temperature above 2h to constant
weight, and then placed in a desiccator, cooled to room temperature and
weighed. </span><span>The moisture content is expressed as a percentage of the mass of the lost sample.</span></span>

</p>
<span id="result_box" class=""><span>2, ash<br />
</span><span>Ash refers to the residue of inorganic salts or oxides remaining after burning at a high temperature, the lower the better.<br />
</span><span>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 </span><span>.<br />
</span><span>3, wear strength strength is the ability of anti-damage activated carbon, the higher the better. </span><span>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 </span><span>The percentage by mass of active carbon sample taken by the particles is taken as the strength of the activated carbon.<br />
</span><span>4, particle size (distribution) Activated carbon particle size of activated carbon bed pressure drop and adsorption speed.<br />
</span></span>
<p>
<span id="result_box" class=""><span>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, </span><span>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 </span><span>distributed.</span></span>

<p>
<span id="result_box" class=""><span></span></span>
</p>
<span id="result_box" class=""><span>5, packing density<br />
</span><span>Also known as pile weight, affect the size of the device design and floating rate.<br />
</span><span>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.<br />
</span><span>6, the fire point<br />
</span></span>
<p>
<span id="result_box" class=""><span>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. </span><span>Therefore, the detection of activated carbon ignition point is necessary. </span><span>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.</span></span>

</p>
<span id="result_box" class=""><span>7, floating rate<br />
</span><span>Flotation rate is a measure of activated carbon in water or floating in the liquid phase of a performance, the lower the better.<br />
</span></span>
<p>
<span id="result_box" class=""><span>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.</span></span>

<span id="result_box" class=""><span>8, pH value<br />
</span><span>pH is an indicator of acid-base activity of activated carbon and needs to be tested for different uses.<br />
</span><span>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. </span><span>Take boiled distilled water 100mL, add the flask and charcoal shake. </span><span>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.</span></span>ifagoup.com
