China Chemical Information Network on April 30 News: April 19, Shijiazhuang City, Jin Date kinds of paint, Ltd. announced that the company after nearly five years of research, has finally successfully developed China's first for the methanol tank wall static conductive anti-corrosion coatings, troubled methanol and downstream industry for many years of corrosion problem since solved. The paint has been recently in Xinjiang Kuqa new Chemical Co., Ltd.
150,000 tons of dimethyl ether project methanol tank wall corrosion engineering successful application of coating is to achieve the desired effect. At present, the new product has entered the expert demonstration program. Domestic methanol industry safety accident-prone, mostly with the methanol storage tank corrosion caused by leaks. Jin Date kinds of paint company for this situation, the development of successful new anti-corrosion coating. The company General Manager Liu further Kangjie Shao, this coating production process is the first in the heat, add the catalyst under the conditions of resin with prepared low viscosity, corrosion performance, flexibility, good film forming resin, reloading and shallow color composite pigments coated metal oxide conductive medium, functional additives, by the synergistic technology preparation of highly active curing agent, prepared crosslinking density of the membrane material. The paint curing speed, high hardness, antistatic, the ability of different concentrations of methanol and water erosion can greatly extend the methanol storage tank service life and reduce maintenance times. It is understood that alcohol molecular weight of a small, strong liquidity, easily in the low areas accumulate, and can easily absorb water, causing tank corrosion.
At present foreign markets for methanol storage tank materials are mostly austenitic stainless steel. The material costs are relatively high, the domestic market is difficult to bear. Domestic methanol storage most of the ordinary carbon steel storage tanks, usually do seven layers of epoxy glass, steel wall protection, but most of the protective layer of 5 years within a total swelling off. Furthermore, this protective layer is not static conductive, prone to static accumulation, causing an explosion. In addition, the domestic methanol storage tanks are also useful for inorganic zinc-rich primer to the corrosion. The material initially be excessive zinc powder leakage, pollution fine methanol, and by pollution of methanol with one of the zinc chemical reaction, the destruction of their corrosion resistance. There's storage tanks of stainless steel spray corrosion, but the cost is very high and difficult to construct, it is difficult in large scale. In recent years, with the methanol accidents gradually increased, the resistance to methanol derivative Anticorrosion Paint demand more urgent.
To this end, the company in 2005 began the development of new anti-corrosion coating. The authority of the department, product antistatic, wear resistance, corrosion resistance and acid and alkali keypoint meet the relevant standards, the company's product standards as the domestic first resistant to methanol derivative Anticorrosion Paint enterprise standards. The product has applied for national invention patent, into the large-scale expansion stage.
