本文回顾了国内外生产与应用聚氟乙烯涂料的情况,探讨了该涂料配方中各组份的作用和成膜过程机理。研究了施工质量对聚氟乙烯涂层性能的影响,和涂层在各类农药中的耐蚀能力,拟定了合理的施工工艺和以聚氟乙烯为防腐涂层的喷雾器生产流程,并进行了批量为1200具的生产性试验。经人工加速试验及田间使用试验结果表明:此种啧雾器寿命可达三年以上,较现在的寿命提高1倍以上,每年可以节约薄板钢材两万多吨。本课题已通过全国性技术鉴定,正在推广应用中。
This paper reviewed the production and application of polyvinyl fluoride paint at home and abroad, and discussed the role of each component in the coating formulation and the mechanism of film forming process. The effect of construction quality on the properties of poly (vinyl fluoride) (PVDF) coatings and the corrosion resistance of coatings in various pesticides were studied, and a reasonable construction process and sprayer production process with polyvinyl fluoride as anti-corrosion coating were developed. Batch of 1200 with the production test. The results of artificial accelerated test and field use test show that the life span of this kind of Mogger can reach more than three years, more than double the current life span and save more than 20,000 tons of sheet steel annually. The subject has passed the national technical appraisal, is being promoted.
