锦天化针对尿素粒度方面所存在的问题,组织开展了质量攻关。通过采用在高温多雨季节向尿素中加入甲醛的方法来提高尿素颗粒的强度;通过探究造粒喷头转速和造粒塔体内通风及空气湿度对尿素颗粒强度的影响,确定了保证尿素颗粒强度高的合理工艺参数;通过改进尿素的贮运系统,降低了尿素颗粒在贮运过程中遭受破损的几率、减少了粉尘的产生。历经几年的改进,锦天化提高了尿素粒度的质量,其尿素产品广受农民欢迎。
Kam days for the urea particle size problems that exist, the organization launched a quality research. Through the use of high temperature and rainy season, the method of adding formaldehyde to urea was used to improve the strength of urea granules. By investigating the influence of granulation nozzle rotating speed, the ventilation inside the granulation tower and the air humidity on the strength of urea granules, the urea granules with high strength Reasonable process parameters; by improving the urea storage and transportation system, reducing the probability of urea particles being damaged during storage and transportation, reducing the generation of dust. After several years of improvement, Kam Tianhua improve the quality of urea particle size, urea products widely welcomed by farmers.
