Application of starch adhesive in organic compound fertilizer granulation
淀粉粘结剂在有机复混肥造粒中的应用

Although mineral binder bonds are widely used in organic compound fertilizers,their inevitable shortcomings limit their application in the organic compound fertilizers.Direct application of crude cornstarch(CK2) adhesive is unfit for granulation of organic compound fertilizers.But the use of liquid adhesive A and dry powder adhesive B(both obtained by the modification of cornstarch)as granulation adhesive in organic compound fertilizer granulation produces granules with quality exceeding Chinese and International Standards.Both two adhesives have granulation percentage greater than 93%,return products less than attapulgites',and used level under 1%.The granules resist crushing forces greater than 10N,and maintain a 100% integrity after immersed in deionized water for 24 hours.Modified cornstarch adhesives practically substitute inorganic binders.Adhesive A and B can be used as granulation adhesive for high nutrient-rich organic compound fertilizers.
