在“以农业为基础、工业为主导”的发展国民经济总方针的指引下,在地县各级领导的大力支持下,我们立足本厂资源,面向农业生产,从1975年元月开始,试制和生产了腐植酸铵农肥。到10月底生产了1,200余吨,供应我区安康、汉阴、石泉等县广大农村,受到贫下中农的欢迎。现就我们试制生产中的一些情况简要介绍如下: 一、原料情况及生产原理: 腐植酸广泛存在于土壤、褐煤、泥炭、堆肥、厩肥等物之中。栲胶废渣经堆腐后其腐败物中含有同褐煤、泥炭中所含腐植酸类似物质,事实上附近部分社队早已用我厂腐烂废渣做肥料。我厂生产的腐植酸铵肥就是用经堆呕、腐烂后的橡椀栲胶废渣与氨作用而制成的。二、工艺流程及设备: 生产过程可分为以下几个工序: 1.原料干燥: Under the guideline of “based on agriculture and industry oriented”, guided by the general guideline for the development of the national economy and with the strong support from leaders at all levels and counties, we have set foot on our resources and oriented to agricultural production. Since January 1975, And the production of humic acid ammonium fertilizer. By the end of October, more than 1,200 tons were produced and supplied to vast rural areas such as Ankang, Hanyin and Shiquan in our district, which were welcomed by poor middle peasants. Now we try to produce some of the brief introduction is as follows: First, the raw materials and production principles: Humic acid widespread in the soil, lignite, peat, composting, manure and other things. The plastic waste residue after heap rot is contained in the same brown coal and humic acid contained in peat. In fact, some of the communes and neighborhood teams have long used the decay residue in our factory as fertilizer. I plant humic acid ammonium fertilizer is used by the reactor vomit, decay after the bowl of rubber waste rubber and ammonia made of the role. Second, the process and equipment: The production process can be divided into the following processes: 1. Raw material drying:
