Coating standard: the national standard revision project of acetone for industrial use has passed the review of the National Standards Committee

Core tip: at the annual meeting of organic chemical branch of national chemical standardization committee held this year, the national standard revision project of acetone for industrial use undertaken by quality supervision and inspection center of Yanshan Petrochemical Company passed the review of Technical Committee Acetone is an important organic raw material, which has a wide range of uses It is mainly used as a solvent for the production of cellulose acetate film plastics and coatings It is also a raw material for the preparation of methyl methacrylate (MMA), epoxy resin and polycarbonate intermediate bisphenol A The main production methods of acetone are cumene method and fermentation method At present, the industrial production of acetone in the world Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings news: at the annual meeting of organic chemical branch of national chemical standardization committee held this year, the national standard revision project of acetone for industrial use undertaken by quality supervision and inspection center of Yanshan Petrochemical Company passed the review of Technical Committee Acetone is an important organic raw material, which has a wide range of uses It is mainly used as a solvent for the production of cellulose acetate film plastics and coatings It is also a raw material for the preparation of methyl methacrylate (MMA), epoxy resin and polycarbonate intermediate bisphenol A The main production methods of acetone are cumene method and fermentation method At present, the industrial production of acetone in the world is mainly by cumene method Most of acetone is the by-product of phenol preparation and one of the products after cumene oxidation The current national standard GB / t6026 "industrial acetone" was issued in 1998 and has been more than ten years With the development of economy, the production of acetone in China has been greatly improved, and the requirements of downstream users have changed a lot The contents of the original standard can no longer adapt to the domestic production and use According to the understanding of users, the pharmaceutical industry has special requirements for benzene content in acetone, but the current national standard has no provisions for this project In order to continuously meet the production needs of downstream units, the National Standardization Committee issued the task of standard revision in 2011, and the task undertaking unit is Yanshan Petrochemical Company After receiving the task, the quality inspection center investigated the production and processing of acetone at home and abroad, held a standard revision meeting attended by domestic acetone production enterprises and processing enterprises, and established the technical route of this standard revision In addition to the improvement of the original index, benzene content index and experimental method are added in the revision of the national standard, which meets the requirements of downstream processing enterprises The national standard revision project of acetone for industrial use passed the review, marking that all the four national standards development and revision work undertaken by Yanshan Petrochemical in 2012 were completed on time and passed the review Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
