The same 1800 tons / year of small melamine plant, Hebei, a company producing 1 ton of melamine raw material consumption is 3.6 tons of urea, a company in Shandong is 3.3 tons, urea consumption is a difference of 0.3 tons per ton. Calculating the price of urea at 1,500 yuan/ton, the benefits of the two companies will differ by nearly one million yuan a year. This is just an example that reporters learned in interviews. Industry sources pointed out that if the control is good, urea consumption can be between 2.9 to 3.0 tons. However, it is understood that at present domestic small melamine plants have a problem of high urea consumption, generally about 3.5 tons, and the highest is as high as 3.8 tons. So where are those devices' high cost of weakness?
Since the beginning of the 1990s, melamine has been swiftly pushed up due to the suspension of production of major equipment in the world and the financial crisis in Southeast Asia. At that time, the product was still a “short, flat, fast†project, and many domestic investments were aimed at. As a result, small devices ranging from 1,000 tons/year to 5,000 tons/year were launched in large numbers. From 2001 to 2003, China’s actual production of melamine rapidly expanded from 130,000 tons to 230,000 tons, with a growth rate of 33%. In 2004 and the first half of this year, the production scale will grow at a higher rate. The actual output this year is expected to be between 350,000 and 400,000 tons. However, 90% of the production is from small devices. These devices are two-step production, with a total urea consumption of around 3.5 tons.
According to industry experts, temperature, medium flow, and dryers are three important factors that reduce the consumption of urea by melamine. The main problem of high consumption of urea in these small devices is that the design and actual production capacity are not matched, which is reflected in the mismatch between the heating furnace and the reaction bed. Not only is the design unreasonable, but the specific operation is still based on the old method of the original device, resulting in high consumption and production failure. For a 1800 ton/year installation with a 2.4-meter fluidized bed, the heating medium flow rate is generally 60m3/hour, while in Shanxi, Hebei, and Shandong there are 25m3/hour, and the reaction bed warm-up area is normal. Double the bed. The annual output of such devices is less than 1,500 tons/year.
The reason that the phenomenon of high consumption of small melamine is widespread is due to the fact that the engineering design of the small melamine project was often copied and even 'a drawing was made all over the country'. Some enterprises also arrange pipelines and equipment according to their own imagination. There are serious problems in the matching of production line design and equipment.
If the scale is small and the cost is high, 1,000 ton/year to 5,000 tons/year equipment is a congenital flaw, then the design is not matched will become the high cost of these companies. In the current situation where the prices of raw materials have risen sharply and market prices are almost equal to the cost, these companies should carry out technical renovations to these cruxes, improve production operations, and lower urea consumption. Otherwise, the inherent deficiency is likely to be 'increased disease because of the high consumption of the day after tomorrow, and even make the company premature.
Disperse dye Printing Thickener as the main additive in the chemical printing industry, because of its excellent thickening, has already appeared in people's field of vision early, its true face is a rheological additive, can be no exaggeration It is said that it only needs to add a small amount of thickener to make it play a big role. Is its advantage only reflected in this amount? No, let me introduce you to the specific advantages of disperse dye printing thickeners.
1. After the consistency of the raw liquid product is increased, the raw liquid is better penetrated into the textile and uniformly sizing.
2. Provide good rheological properties for dyes or pigments, so that they are evenly distributed during printing without splashing and sagging.
3. Better penetration of the dye into the textile, combined with the fibers to form a well-defined, well-defined textile print.
4. The consistency is increased, so that the dye in the printing is fixed, and the reaction product and the residue are more conveniently and easily washed away.
Disperse dye printing thickeners are widely used in the thickening of textile printing and dyeing, coatings, printing and dyeing, sanding cloth, cotton cloth, chemical fiber cloth and other systems.
Hot reports: Where are the soft ribs of small melamine?
In the domestic melamine industry, an annual output of 1,000 tons to 5,000 tons of equipment is regarded as a 'minority'. However, there are also big troubles for the 'small-class generation', such as raw material consumption.
