最近,从有关部门了解到,鉴于农用硝酸铵引发的重特大事故有增多势头,国务院办公厅发出紧急通知,要求各地民爆器材行政主管部门组织对相关企业生产及进口的农用硝酸铵以及硝酸铵含量超过50%的复混肥进行强制检测,凡抗爆性能达不到指标的,一律不准销售和进口。这无疑是2002年9月国务院对农用硝酸铵政策性停产后,再一次加大了对农用硝酸铵的监管力度。检测采取企业送检及行政主管部门抽样的方式进行,经检测达到标准规定的抗爆性能指标的,由指定检测单位国家民用爆破器材质量监督检测中心(南京)出具抗爆性能检测合格证书。自2007年1月1日起,凡未取得抗爆性能检测合格证书的产品,一律不得作为农用生产资料生产、销售、购买、使用。与此同时,以后农用硝酸铵以及硝酸铵含量超过50%的硝酸铵复混肥将3年统检一次,由国家民用爆破器材质量监督检测中心(南京)统一负责,国防科工委、公安部适时组织抽检并公布结果。在农用硝酸铵政策性停产后,原硝酸铵生产厂家转产硝酸铵钙,具有生产原料易得、产品成本低、原装置利用率高、市场竞争力强等优势,是一条硝酸铵改性转产的有效途径。硝酸铵钙在降低氮含量的同时增添了作物生长所需的钙元素,以减少其能量物质,使之失去燃爆性,并使肥料的总养分和肥效与硝酸铵相当或有所提高,是一种值得推广应用的肥料。
Recently, from relevant departments, in view of the aggravating momentum caused by agricultural ammonium nitrate-induced major accidents, the State Council General Office issued an urgent circular calling for the explosion-proof materials around the administrative departments in charge of production and import of agricultural enterprises related to ammonium nitrate and ammonium nitrate More than 50% of the content of compost compulsory testing, where the antiknock performance of less than indicators, are not allowed to sell and import. This is undoubtedly the state council in September 2002 for the agricultural production of ammonium nitrate discontinued, once again stepped up the supervision of agricultural ammonium nitrate. The test shall be conducted by means of sampling by the enterprise and by the competent administrative department. After being tested to meet the antiknock performance requirements of the standard, the certificate of antiknock performance test shall be issued by the National Testing Center for Civil Explosives (Nanjing) of the designated testing unit. From January 1, 2007 onwards, those who have not obtained antiknock performance testing certificate shall not be used as agricultural means of production, sale, purchase, use. At the same time, after the agricultural ammonium nitrate and ammonium nitrate content of more than 50% of the ammonium nitrate compound fertilizer will be three years once again by the National Civil Engineering Quality Supervision and Inspection Center (Nanjing) unified charge of the National Defense Science and Industry Commission, Ministry of Public Security Timely organize sampling and publish the results. In the agricultural production of ammonium nitrate after the discontinuation of the policy, the original manufacturer of ammonium nitrate ammonium nitrate conversion of calcium, raw materials with easy availability, low product cost, high utilization of the original device, the market competitiveness and other advantages, is a modified ammonium nitrate conversion Effective Ways. Calcium ammonium nitrate reduces the nitrogen content while adding the calcium needed for crop growth, to reduce its energy substances, so that the loss of explosive nature, and make the total nutrient and fertilizer efficiency and ammonium nitrate equivalent or increased, is A worth promoting the use of fertilizer.
