The use of hydrophobic material: Inert powder: the first is the use of anti-caking agents [41]. The powder used primarily inert substances that do not dissolve in water and fertilizers nor chemical effects, such as clay, talc, zeolite, etc., there are very fine particles, low density, strong adhesion characteristics. Mechanical isolation and absorption of the particle surface moisture, prevents the formation of grain junction points. This method is low cost, high temperature anti-caking agent of products, but the amount of large, poor performance if used alone, it is easy to decompose fertilizers (eg ammonium nitrate) are generally ineffective, causing an increase in fertilizer dust content, high temperature anti-caking agent , fertilizer effectively decreased fertilizer caking is caused by many factors, in the manufacture of fertilizer should try to weaken the influence of these factors, a lot of work for this research scholars, high temperature anti-caking agent manufacturers , broadly grouped into two ways [5]: First, through optimizing production operation process to weaken the agglomeration of fertilizers, such as the use of modern production technology and the introduction of new granulation and drying equipment, better storage environment conditions to improve packaging conditions and packaging methods, the use of moisture-proof packaging materials; Another way is to use fertilizer anti-caking agent, in order to reduce the moisture content of products, improve product strength, uniformity and loose and so on. High-temperature anti-caking agent credibility _ Weifang Fuyuan (certified) _ High-temperature anti-caking agents provided by the Environmental Protection Technology Co., Ltd. Weifang Fuyuan.
