普通过磷酸钙（ssp）

【产品名称】普通过磷酸钙（ssp）

【产品简介】普通过磷酸钙（ssp）是一种水溶性速效磷肥，其有效磷含量在16％以上。该产品可作基肥、追肥、种肥和生产复混肥的原料；广泛适用于水稻、小麦、玉米、高梁、棉花、瓜果、蔬菜等各种粮食作物和经济作物；广泛适用于红壤、黄壤、棕壤、黄潮土、黑土、褐土、紫色土、白浆土等各种土质；尤其适合于我国华北、东北、西北等缺磷地区施用。

【brief introduction】

sspisa water soluble phosphate fertilizer which can take speedy effect, containing more than 16% available phosphorus. this product can be used as basal fertilizer, top dressing, seed fertilizer and raw materials of producing compound fertilizers; it is very helpful to the growth of rice, wheat, corn, sorghum, cotton, fruits, vegetables and other food crops and economic crops; it can be widely used in soils with different , like red soil, yellow soil, brown soil, fluvo-aquic soil, black soil, cinnamon soil, purple soil, albic soil; especiallysoilin the north, the northeast, the northwest of china and other areas where soil is lack of phosphorus.

【生产工艺流程描述】企业采用传统的化成法工艺进行生产。硫酸与磷矿粉进行混合（化成）反应，反应物料：（1）经过堆置熟化得到粉状产品；（2）经过造粒、干燥、筛分、冷却等工序制得粒状产品。

【production process】

we adopt the traditional chemical method (den) to conduct the production process. after mixing the sulfuric acid and the phosphate rock powder, reaction materials are made: (1) stack up for ripening and get the powder product; (2) granulate, dry, sieve, cool the powder product, and get the granular product.
