The hottest nano inorganic modified polyvinyl alco
2022-10-14- Detail
Successful development of nano inorganic modified polyvinyl alcohol aqueous solution technology recently came out in Gaoyang County, Hebei Province, reaching the world's advanced level. According to reports, nano non-ferrous materials increased by 18.72% year-on-year; The net profit is 38.6594 million yuan. The organic modified polyvinyl alcohol aqueous solution adopts the composite coating process. The high barrier film produced has excellent transparency, gloss, fragrance retention, polarity, oil resistance and organic solvent resistance, and is non-toxic and pollution-free. It is an environmental protection product. The production process of this solution is simple, the comprehensive cost is low, and the application field is wide. It can be applied to all kinds of packaging such as clothing, leather, documents and archives, chemical raw materials, machinery, food and so on. According to the inspection of the inspection room of China Packaging Research and testing center, compared with PVA before modification, the oxygen permeability of this new product is reduced by 3 times and the water vapor permeability is reduced by 1 time, which is far lower than the relevant indicators of similar foreign products and reaches the world advanced level. However, the cost is only 1/7 of EVOH. It is understood that at present, only a few developed countries in the world can produce similar products, and the oxygen permeability is high, and the cost is high. Regardless of the performance and price, the nano inorganic modified polyethanol aqueous solution technology developed by Gaoyang County has great advantages. The concentration of vanadium electrolyte used by most vanadium battery manufacturers is 1.5 ⑴ 7 mol/l strong competitive strength and broad development prospects
