改革开放以来,我国三聚氰胺的生产量和消费量均获得了较大增长。90年代初,我国采用国内技术建成了一批1000～6000t/a的生产装置,生产技术达到了较高水平,产品质量也与国外相差无几。到90年代中期,我国三聚氰胺生产能力已达到4万t/a左右,国内消费和出口各占50%左右。1997年以来,三聚氰胺一度货紧价扬,国内许多企业看好该产品并纷纷投资建设,我国三聚氰胺生产企业由原先的不足20家猛增至了50多家,生产能力由96年的4.5万t/a增加到了目前的15.6万t/a,还有部分装置正在建设。由于引进了国外的高压法技术,现我国几种工艺技术均已具备。2000年底,我国将成为世界上最大的三聚氰胺生产国。
Since the reform and opening up, China’s production and consumption of melamine have seen a large increase. In the early 1990s, China used domestic technology to build a batch of 1000-6000t/a production facilities, and the production technology reached a high level, and the quality of products was also similar to that of foreign countries. By the mid-1990s, China’s melamine production capacity had reached about 40,000 t/a, and domestic consumption and exports accounted for about 50% each. Since 1997, melamine has been tightly priced, many domestic companies are optimistic about the product and have invested in construction. The melamine production enterprises in China have increased from less than 20 to more than 50, and the production capacity has been 45,000 t/year in 1996. a increased to the current 156,000 t/a, and some of the devices are under construction. Due to the introduction of foreign high-pressure method technology, several kinds of process technologies are now available in China. By the end of 2000, China will become the world’s largest melamine producer.
