Non-surfactant or a hydrophobic substance class anti-caking agent. Agent class of anti-caking agent mechanism fertilizer granules in the surface of the non-water-repellent film surface, in order to prevent or inhibit moisture fertilizer powder. Adding fertilizer to promote the formation of some inorganic salt soluble fertilizer complex in internal anti-caking agent, can improve moisture absorption [40]. Such as 30 ℃, pure ammonium nitrate hygroscopic point of 59.4%, but sales of water-soluble fertilizer anti-caking agent after adding ammonium sulfate to form NH4NO3? (NH4) 2SO4 complex salt, moisture absorption point increase 62.3% [41]. You can also add a small amount of water-soluble iron salts substance. Application of wet process phosphoric acid manufacture imitate ammonium-based fertilizers fat soluble anti-caking agent, phosphoric acid itself contains iron, aluminum phosphate impurities to form a water-insoluble crystalline mesh structure of these crystals soluble fertilizer factory anti-caking agent, as amorphous gel, the product sclerosis, inhibition of fertilizer between [5.40].
