将化肥、农药设法悬置于溶剂上部(简称上悬法),可以加快溶解速度,改善溶液质量。原理:溶质在溶液中存在着溶液和结晶两个相反的过程。上悬法由于容质置溶剂上部,溶解的粒子在重力的作用下,可以摆脱结晶作用。上悬法有较快的溶解速度,加上上悬法溶质的装载体可把不溶杂质滤除,而常规法则无此功能。所以上悬法可以改善溶液质量。本法适用于水施的一切化肥和水溶性农药原理的溶解。方法是根据化肥或农药的颗粒大小,选择既透水又
The fertilizer, pesticides try to suspend the solvent in the upper part (referred to as hanging method), can speed up the dissolution rate, improve the quality of the solution. Principle: Solute in solution there are two opposite process of solution and crystallization. On the suspended method due to the content of solvent upper part of the dissolved particles under the action of gravity, you can get rid of crystallization. On the suspension method has a faster dissolution rate, coupled with the suspension method of solute loading insoluble impurities can be removed, while the normal rule of no such function. So hanging on the law can improve the quality of solution. This Law applies to the dissolution of all fertilizers and water-soluble pesticides in water facilities. The method is based on the particle size of fertilizers or pesticides, the choice of both permeate and
