Embodiment 1
[0017] Example 1 Using solid paraffin as a coating agent to wrap fertilizer powder
[0018] Test tube wrapping method: Add 10g of powder and measured paraffin into the test tube, keep it at a constant temperature of 90°C until all the paraffin is vaporized and evenly wrapped the powder, during which the paraffin must not be leaked. After cooling, samples were taken to measure the contact angle.
[0019] In the measurement of the contact angle of the Washburn dynamic method, the water is set to completely wet the surface of the uncoated powder, and the contact angle θ=0 0 , see Table 1 for the contact angles of the fertilizer product powders wrapped in liquid paraffin.
[0020] Table 1
[0021]
[0022] Under the conditions of enhanced caking test temperature of 24°C and relative humidity of 80%, the sample powder withstands about 710kg / m 2 Take out the sample after 24 hours; use a needle-shaped glass rod with a diameter of 2.16mm to measure the mass of the weight require...
Embodiment 2
[0026] Example 2 Using Cetyl Alcohol as a Coating Agent to Coat Fertilizer Powder
[0027] The hot nitrogen gas brings out steam through the boiling cetyl alcohol, so that it evenly wraps the preheated sample powder. After cooling, samples are taken to measure the contact angle, and the amount of cetyl alcohol on the surface of the powder is determined by oxidation. The results are shown in Table 3.
[0028] table 3
[0029]
[0030] In the caking test, the results of the mass of the weight required to insert the sample block are shown in Table 4.
[0031] Table 4
[0032]
[0033] The test results show that the mass of weights required after wrapping is greatly reduced, indicating that the possibility of monoammonium phosphate powder agglomeration is greatly reduced.
Embodiment 3
[0034] Embodiment 3 adopts incomplete burning of turpentine, so that it produces carbon black soot and wraps heavy superphosphate product powder, and its contact angle~90 0 .
