Determination of apparent density of 3
3.1 Instruments and materials
It should include at least the following equipment and materials.
a) balance. the largest weighing 500g, the measurement accuracy 0.01g. With a special sealing glass (see Figure 1).
b) melting wax pot. pot volume size can make samples were completely immersed in liquid wax.
c) beaker. a standard volume of 250mL glass beaker.
d) basket. sieve making, basket mouth diameter of 50mm.
e) hanging silk. silk or nylon cord.
f) Drinking water. in line with GB 5749.
g) Paraffin. comply with GB 7189.
3.2 Determination of step
3.2.1 Method of sealing wax with mineral and medicinal products calcined sample waterproofing.
3.2.1.1 Sampling. from fossil shellfish herbs or herbs, samples taken while about 10mm ~ 30mm approximate cube 3, Shuhei edge
Angle, the sample surface is easy to remove ash falling debris, weighing in the balance.
3.2.1.2 Wax. tied with a hanging wire sample, placed in the melting temperature of the liquid wax 65 ℃ ~ 75 ℃ in 1s ~ 2s, removed, dried and weighed.
3.2.2 Determination of apparent density and calcined mineral medicinal products with drainage method.
3.2.2.1 school scale. capacity will be filled with drinking water in a beaker half put in the balance, and the balance at the top take a crossbar, crossbar hanging basket, hanging
Basket immersed in drinking water, the balance is adjusted to display 0.00g, shown in Figure 1.
3.2.2.2 Weigh-in. The sample has a sealing wax placed in the basket, shown in Figure 2, and to ensure the basket with sample is completely under water, do not touch
Beaker wall, weighing quality of water discharge samples. We have to take the sample after immersion in water bubble phenomenon as observed when weighing sealing wax, and the balance is constantly changing depending on the number of
Small, samples should be removed from the water, wipe the surface of the water, again called on the mass balance, this time to check the quality and whether there is poor quality before
